141 ideas

1. Philosophy / F. Analytic Philosophy / 5. Linguistic Analysis
'Socrates is human' expresses predication, and 'Socrates is a man' expresses identity [Russell]
     Full Idea: The is of 'Socrates is human' expresses the relation of subject and predicate; the is of 'Socrates is a man' expresses identity. It is a disgrace to the human race that it employs the same word 'is' for these entirely different ideas.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XVI)
     A reaction: Does the second one express identity? It sounds more like membership to me. 'Socrates is the guy with the hemlock' is more like identity.
2. Reason / B. Laws of Thought / 2. Sufficient Reason
Both nature and reason require that everything has a cause [Rousseau]
     Full Idea: Under the law of reason nothing takes place without a cause, any more than under the law of nature.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.04)
     A reaction: Is this the influence of Leibniz? Note that the principle is identified in two different areas, so in nature we may say 'everything has a cause', and in rationality we may say 'there is a reason for everything'. But are these the same?
2. Reason / D. Definition / 3. Types of Definition
A definition by 'extension' enumerates items, and one by 'intension' gives a defining property [Russell]
     Full Idea: The definition of a class or collection which enumerates is called a definition by 'extension', and one which mentions a defining property is called a definition by 'intension'.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], II)
     A reaction: In ordinary usage we take intensional definitions for granted, so it is interesting to realise that you might define 'tiger' by just enumerating all the tigers. But all past tigers? All future tigers? All possible tigers which never exist?
2. Reason / F. Fallacies / 8. Category Mistake / a. Category mistakes
The sentence 'procrastination drinks quadruplicity' is meaningless, rather than false [Russell, by Orenstein]
     Full Idea: Russell proposed (in his theory of types) that sentences like 'The number two is fond of cream cheese' or 'Procrastination drinks quadruplicity' should be regarded as not false but meaningless.
     From: report of Bertrand Russell (Introduction to Mathematical Philosophy [1919]) by Alex Orenstein - W.V. Quine Ch.3
     A reaction: This seems to be the origin of the notion of a 'category mistake', which Ryle made famous. The problem is always poetry, where abstractions can be reified, or personified, and meaning can be squeezed out of almost anything.
3. Truth / F. Semantic Truth / 1. Tarski's Truth / b. Satisfaction and truth
An argument 'satisfies' a function φx if φa is true [Russell]
     Full Idea: We say that an argument a 'satisfies' a function φx if φa is true.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XV)
     A reaction: We end up with Tarski defining truth in terms of satisfaction, so we shouldn't get too excited about what he achieved (any more than he got excited).
4. Formal Logic / A. Syllogistic Logic / 2. Syllogistic Logic
The Darapti syllogism is fallacious: All M is S, all M is P, so some S is P' - but if there is no M? [Russell]
     Full Idea: Some moods of the syllogism are fallacious, e.g. 'Darapti': 'All M is S, all M is P, therefore some S is P', which fails if there is no M.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XV)
     A reaction: This critique rests on the fact that the existential quantifier entails some existence, but the universal quantifier does not.
4. Formal Logic / F. Set Theory ST / 3. Types of Set / d. Infinite Sets
We can enumerate finite classes, but an intensional definition is needed for infinite classes [Russell]
     Full Idea: We know a great deal about a class without enumerating its members …so definition by extension is not necessary to knowledge about a class ..but enumeration of infinite classes is impossible for finite beings, so definition must be by intension.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], II)
     A reaction: Presumably mathematical induction (which keeps apply the rule to extend the class) will count as an intension here.
4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / b. Axiom of Extensionality I
Members define a unique class, whereas defining characteristics are numerous [Russell]
     Full Idea: There is only one class having a given set of members, whereas there are always many different characteristics by which a given class may be defined.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], II)
4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / f. Axiom of Infinity V
Infinity says 'for any inductive cardinal, there is a class having that many terms' [Russell]
     Full Idea: The Axiom of Infinity may be enunciated as 'If n be any inductive cardinal number, there is at least one class of individuals having n terms'.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XIII)
     A reaction: So for every possible there exists a set of terms for it. Notice that they are 'terms', not 'objects'. We must decide whether we are allowed terms which don't refer to real objects.
We may assume that there are infinite collections, as there is no logical reason against them [Russell]
     Full Idea: There is no logical reason against infinite collections, and we are therefore justified, in logic, in investigating the hypothesis that there are such collections.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], VIII)
4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / j. Axiom of Choice IX
The British parliament has one representative selected from each constituency [Russell]
     Full Idea: We have a class of representatives, who make up our Parliament, one being selected out of each constituency.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XII)
     A reaction: You can rely on Russell for the clearest illustrations of these abstract ideas. He calls the Axiom of Choice the 'Multiplicative' Axiom.
Choice shows that if any two cardinals are not equal, one must be the greater [Russell]
     Full Idea: The [Axiom of Choice] is also equivalent to the assumption that of any two cardinals which are not equal, one must be the greater.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XII)
     A reaction: It is illuminating for the uninitiated to learn that this result can't be taken for granted (with infinite cardinals).
Choice is equivalent to the proposition that every class is well-ordered [Russell]
     Full Idea: Zermelo has shown that [the Axiom of Choice] is equivalent to the proposition that every class is well-ordered, i.e. can be arranged in a series in which every sub-class has a first term (except, of course, the null class).
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XII)
     A reaction: Russell calls Choice the 'Multiplicative' Axiom.
We can pick all the right or left boots, but socks need Choice to insure the representative class [Russell]
     Full Idea: Among boots we distinguish left and right, so we can choose all the right or left boots; with socks no such principle suggests itself, and we cannot be sure, without the [Axiom of Choice], that there is a class consisting of one sock from each pair.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XII)
     A reaction: A deservedly famous illustration of a rather tricky part of set theory.
4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / p. Axiom of Reducibility
Reducibility: a family of functions is equivalent to a single type of function [Russell]
     Full Idea: The Axiom of Reducibility says 'There is a type of a-functions such that, given any a-function, it is formally equivalent to some function of the type in question'. ..It involves all that is really essential in the theory of classes. But is it true?
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XVII)
     A reaction: I take this to say that in the theory of types, it is possible to reduce each level of type down to one type.
4. Formal Logic / F. Set Theory ST / 5. Conceptions of Set / c. Logical sets
Propositions about classes can be reduced to propositions about their defining functions [Russell]
     Full Idea: It is right (in its main lines) to say that there is a reduction of propositions nominally about classes to propositions about their defining functions.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XVII)
     A reaction: The defining functions will involve the theory of types, in order to avoid the paradoxes of naïve set theory. This is Russell's strategy for rejecting the existence of sets.
4. Formal Logic / F. Set Theory ST / 7. Natural Sets
Russell's proposal was that only meaningful predicates have sets as their extensions [Russell, by Orenstein]
     Full Idea: Russell's solution (in the theory of types) consists of restricting the principle that every predicate has a set as its extension so that only meaningful predicates have sets as their extensions.
     From: report of Bertrand Russell (Introduction to Mathematical Philosophy [1919]) by Alex Orenstein - W.V. Quine Ch.3
     A reaction: There might be a chicken-and-egg problem here. How do you decide the members of a set (apart from ostensively) without deciding the predicate(s) that combine them?
4. Formal Logic / F. Set Theory ST / 8. Critique of Set Theory
Classes are logical fictions, and are not part of the ultimate furniture of the world [Russell]
     Full Idea: The symbols for classes are mere conveniences, not representing objects called 'classes'. Classes are in fact logical fictions; they cannot be regarded as part of the ultimate furniture of the world.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], Ch.18), quoted by Stewart Shapiro - Thinking About Mathematics 5.2
     A reaction: I agree. For 'logical fictions' read 'abstractions'. To equate abstractions with fictions is to underline the fact that they are a human creation. They are either that or platonic objects - there is no middle way.
5. Theory of Logic / A. Overview of Logic / 4. Pure Logic
All the propositions of logic are completely general [Russell]
     Full Idea: It is part of the definition of logic that all its propositions are completely general.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XV)
5. Theory of Logic / A. Overview of Logic / 8. Logic of Mathematics
In modern times, logic has become mathematical, and mathematics has become logical [Russell]
     Full Idea: Logic has become more mathematical, and mathematics has become more logical. The consequence is that it has now become wholly impossible to draw a line between the two; in fact, the two are one.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XVIII)
     A reaction: This appears to be true even if you reject logicism about mathematics. Logicism is sometimes rejected because it always ends up with a sneaky ontological commitment, but maybe mathematics shares exactly the same commitment.
5. Theory of Logic / C. Ontology of Logic / 1. Ontology of Logic
Logic can only assert hypothetical existence [Russell]
     Full Idea: No proposition of logic can assert 'existence' except under a hypothesis.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XVIII)
     A reaction: I am prepared to accept this view fairly dogmatically, though Musgrave shows some of the difficulties of the if-thenist view (depending on which 'order' of logic is being used).
Logic is concerned with the real world just as truly as zoology [Russell]
     Full Idea: Logic is concerned with the real world just as truly as zoology, though with its more abstract and general features.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XVI)
     A reaction: I love this idea and am very sympathetic to it. The rival view seems to be that logic is purely conventional, perhaps defined by truth tables etc. It is hard to see how a connective like 'tonk' could be self-evidently silly if it wasn't 'unnatural'.
Logic can be known a priori, without study of the actual world [Russell]
     Full Idea: Logical propositions are such as can be known a priori, without study of the actual world.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XVIII)
     A reaction: This remark constrasts strikingly with Idea 12444, which connects logic to the actual world. Is it therefore a priori synthetic?
5. Theory of Logic / F. Referring in Logic / 1. Naming / b. Names as descriptive
Asking 'Did Homer exist?' is employing an abbreviated description [Russell]
     Full Idea: When we ask whether Homer existed, we are using the word 'Homer' as an abbreviated description.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XVI)
     A reaction: It is hard to disagree with Russell over this rather unusual example. It doesn't seem so plausible when Ottiline refers to 'Bertie'.
Russell admitted that even names could also be used as descriptions [Russell, by Bach]
     Full Idea: Russell clearly anticipated Donnellan when he said proper names can also be used as descriptions, adding that 'there is nothing in the phraseology to show whether they are being used in this way or as names'.
     From: report of Bertrand Russell (Introduction to Mathematical Philosophy [1919], p.175) by Kent Bach - What Does It Take to Refer? 22.2 L1
     A reaction: This seems also to anticipate Strawson's flexible and pragmatic approach to these things, which I am beginning to think is correct.
Names are really descriptions, except for a few words like 'this' and 'that' [Russell]
     Full Idea: We can even say that, in all such knowledge as can be expressed in words, with the exception of 'this' and 'that' and a few other words of which the meaning varies on different occasions - no names occur, but what seem like names are really descriptions.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XVI)
     A reaction: I like the caveat about what is expressed in words. Russell is very good at keeping non-verbal thought in the picture. This is his famous final reduction of names to simple demonstratives.
5. Theory of Logic / F. Referring in Logic / 1. Naming / f. Names eliminated
The only genuine proper names are 'this' and 'that' [Russell]
     Full Idea: In all knowledge that can be expressed in words - with the exception of "this" and "that", and a few other such words - no genuine proper names occur, but what seem like genuine proper names are really descriptions
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XVI)
     A reaction: This is the terminus of Russell's train of thought about descriptions. Suppose you point to something non-existent, like a ghost in a misty churchyard? You'd be back to the original problem of naming a non-existent!
5. Theory of Logic / F. Referring in Logic / 2. Descriptions / a. Descriptions
'I met a unicorn' is meaningful, and so is 'unicorn', but 'a unicorn' is not [Russell]
     Full Idea: In 'I met a unicorn' the four words together make a significant proposition, and the word 'unicorn' is significant, …but the two words 'a unicorn' do not form a group having a meaning of its own. It is an indefinite description describing nothing.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XVI)
6. Mathematics / A. Nature of Mathematics / 2. Geometry
If straight lines were like ratios they might intersect at a 'gap', and have no point in common [Russell]
     Full Idea: We wish to say that when two straight lines cross each other they have a point in common, but if the series of points on a line were similar to the series of ratios, the two lines might cross in a 'gap' and have no point in common.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], X)
     A reaction: You can make a Dedekind Cut in the line of ratios (the rationals), so there must be gaps. I love this idea. We take for granted intersection at a point, but physical lines may not coincide. That abstract lines might fail also is lovely!
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / b. Types of number
New numbers solve problems: negatives for subtraction, fractions for division, complex for equations [Russell]
     Full Idea: Every generalisation of number has presented itself as needed for some simple problem. Negative numbers are needed to make subtraction always possible; fractions to make division always possible; complex numbers to make solutions of equations possible.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], VII)
     A reaction: Doesn't this rather suggest that we made them up? If new problems turn up, we'll invent another lot. We already have added 'surreal' numbers.
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / c. Priority of numbers
Could a number just be something which occurs in a progression? [Russell, by Hart,WD]
     Full Idea: Russell toyed with the idea that there is nothing to being a natural number beyond occurring in a progression
     From: report of Bertrand Russell (Introduction to Mathematical Philosophy [1919], p.8) by William D. Hart - The Evolution of Logic 5
     A reaction: How could you define a progression, without a prior access to numbers? - Arrange all the objects in the universe in ascending order of mass. Use scales to make the selection. Hence a finite progression, with no numbers!
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / i. Reals from cuts
A series can be 'Cut' in two, where the lower class has no maximum, the upper no minimum [Russell]
     Full Idea: There is no maximum to the ratios whose square is less than 2, and no minimum to those whose square is greater than 2. This division of a series into two classes is called a 'Dedekind Cut'.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], VII)
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / j. Complex numbers
A complex number is simply an ordered couple of real numbers [Russell]
     Full Idea: A complex number may be regarded and defined as simply an ordered couple of real numbers
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], VII)
6. Mathematics / A. Nature of Mathematics / 3. Nature of Numbers / m. One
Discovering that 1 is a number was difficult [Russell]
     Full Idea: The discovery that 1 is a number must have been difficult.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], I)
     A reaction: Interesting that he calls it a 'discovery'. I am tempted to call it a 'decision'.
6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / c. Counting procedure
Numbers are needed for counting, so they need a meaning, and not just formal properties [Russell]
     Full Idea: We want our numbers to be such as can be used for counting common objects, and this requires that our numbers should have a definite meaning, not merely that they should have certain formal properties.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], I)
     A reaction: Why would just having certain formal properties be insufficient for counting? You just need an ordered series of unique items. It isn't just that we 'want' this. If you define something that we can't count with, you haven't defined numbers.
6. Mathematics / A. Nature of Mathematics / 4. Using Numbers / f. Arithmetic
The formal laws of arithmetic are the Commutative, the Associative and the Distributive [Russell]
     Full Idea: The usual formal laws of arithmetic are the Commutative Law [a+b=b+a and axb=bxa], the Associative Law [(a+b)+c=a+(b+c) and (axb)xc=ax(bxc)], and the Distributive Law [a(b+c)=ab+ac)].
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], IX)
6. Mathematics / A. Nature of Mathematics / 5. The Infinite / a. The Infinite
Infinity and continuity used to be philosophy, but are now mathematics [Russell]
     Full Idea: The nature of infinity and continuity belonged in former days to philosophy, but belongs now to mathematics.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], Pref)
     A reaction: It is hard to disagree, since mathematicians since Cantor have revealed so much about infinite numbers (through set theory), but I think it remains an open question whether philosophers have anything distinctive to contribute.
6. Mathematics / B. Foundations for Mathematics / 4. Axioms for Number / a. Axioms for numbers
The definition of order needs a transitive relation, to leap over infinite intermediate terms [Russell]
     Full Idea: Order must be defined by means of a transitive relation, since only such a relation is able to leap over an infinite number of intermediate terms. ...Without it we would not be able to define the order of magnitude among fractions.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], IV)
6. Mathematics / B. Foundations for Mathematics / 4. Axioms for Number / d. Peano arithmetic
Any founded, non-repeating series all reachable in steps will satisfy Peano's axioms [Russell]
     Full Idea: Given any series which is endless, contains no repetitions, has a beginning, and has no terms that cannot be reached from the beginning in a finite number of steps, we have a set of terms verifying Peano's axioms.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], I)
'0', 'number' and 'successor' cannot be defined by Peano's axioms [Russell]
     Full Idea: That '0', 'number' and 'successor' cannot be defined by means of Peano's five axioms, but must be independently understood.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], I)
6. Mathematics / B. Foundations for Mathematics / 5. Definitions of Number / d. Hume's Principle
A number is something which characterises collections of the same size [Russell]
     Full Idea: The number 3 is something which all trios have in common, and which distinguishes them from other collections. A number is something that characterises certain collections, namely, those that have that number.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], II)
     A reaction: This is a verbal summary of the Fregean view of numbers, which marks the arrival of set theory as the way arithmetic will in future be characterised. The question is whether set theory captures all aspects of numbers. Does it give a tool for counting?
6. Mathematics / B. Foundations for Mathematics / 7. Mathematical Structuralism / a. Structuralism
What matters is the logical interrelation of mathematical terms, not their intrinsic nature [Russell]
     Full Idea: What matters in mathematics is not the intrinsic nature of our terms, but the logical nature of their interrelations.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], VI)
     A reaction: If they have an instrinsic nature, that would matter far more, because that would dictate the interrelations. Structuralism seems to require that they don't actually have any intrinsic nature.
6. Mathematics / C. Sources of Mathematics / 5. Numbers as Adjectival
Maybe numbers are adjectives, since 'ten men' grammatically resembles 'white men' [Russell]
     Full Idea: 'Ten men' is grammatically the same form as 'white men', so that 10 might be thought to be an adjective qualifying 'men'.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XVIII)
     A reaction: The immediate problem, as Frege spotted, is that such expressions can be rephrased to remove the adjective (by saying 'the number of men is ten').
6. Mathematics / C. Sources of Mathematics / 6. Logicism / a. Early logicism
For Russell, numbers are sets of equivalent sets [Russell, by Benacerraf]
     Full Idea: Russell's own stand was that numbers are really only sets of equivalent sets.
     From: report of Bertrand Russell (Introduction to Mathematical Philosophy [1919]) by Paul Benacerraf - Logicism, Some Considerations (PhD) p.168
     A reaction: Benacerraf is launching a nice attack on this view, based on our inability to grasp huge numbers on this basis, or to see their natural order.
6. Mathematics / C. Sources of Mathematics / 10. Constructivism / e. Psychologism
There is always something psychological about inference [Russell]
     Full Idea: There is always unavoidably something psychological about inference.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XIV)
     A reaction: Glad to find Russell saying that. Only pure Fregeans dream of a logic that rises totally above the minds that think it. See Robert Hanna on the subject.
7. Existence / A. Nature of Existence / 1. Nature of Existence
Existence can only be asserted of something described, not of something named [Russell]
     Full Idea: Existence can only be asserted of something described, not of something named.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XVIII)
     A reaction: This is the motivation behind Russell's theory of definite descriptions, and epitomises the approach to ontology through language. Sounds wrong to me!
7. Existence / D. Theories of Reality / 7. Fictionalism
Classes are logical fictions, made from defining characteristics [Russell]
     Full Idea: Classes may be regarded as logical fictions, manufactured out of defining characteristics.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], II n1)
     A reaction: I agree with this. The idea that in addition to the members there is a further object, the set containing them, is absurd. Sets are a tool for thinking about the world.
8. Modes of Existence / A. Relations / 4. Formal Relations / a. Types of relation
If a relation is symmetrical and transitive, it has to be reflexive [Russell]
     Full Idea: It is obvious that a relation which is symmetrical and transitive must be reflexive throughout its domain.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], II)
     A reaction: Compare Idea 13543! The relation will return to its originator via its neighbours, rather than being directly reflexive?
'Asymmetry' is incompatible with its converse; a is husband of b, so b can't be husband of a [Russell]
     Full Idea: The relation of 'asymmetry' is incompatible with the converse. …The relation 'husband' is asymmetrical, so that if a is the husband of b, b cannot be the husband of a.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], V)
     A reaction: This is to be contrasted with 'non-symmetrical', where there just happens to be no symmetry.
9. Objects / D. Essence of Objects / 3. Individual Essences
The essence of individuality is beyond description, and hence irrelevant to science [Russell]
     Full Idea: The essence of individuality always eludes words and baffles description, and is for that very reason irrelevant to science.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], VI)
     A reaction: [context needed for a full grasp of this idea] Russell seems to refer to essence as much as to individuality. The modern essentialist view is that essences are not beyond description after all. Fundamental physics is clearer now than in 1919.
10. Modality / B. Possibility / 8. Conditionals / c. Truth-function conditionals
Inferring q from p only needs p to be true, and 'not-p or q' to be true [Russell]
     Full Idea: In order that it be valid to infer q from p, it is only necessary that p should be true and that the proposition 'not-p or q' should be true.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XIV)
     A reaction: Rumfitt points out that this approach to logical consequences is a denial of any modal aspect, such as 'logical necessity'. Russell observes that for a good inference you must know the disjunction as a whole. Could disjunction be modal?...
All forms of implication are expressible as truth-functions [Russell]
     Full Idea: There is no need to admit as a fundamental notion any form of implication not expressible as a truth-function.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XIV)
     A reaction: Note that this is from a book about 'mathematical' philosophy. Nevertheless, it seems to have the form of a universal credo for Russell. He wasn't talking about conditionals here. Maybe conditionals are not implications (in isolation, that is).
10. Modality / E. Possible worlds / 1. Possible Worlds / a. Possible worlds
If something is true in all possible worlds then it is logically necessary [Russell]
     Full Idea: Saying that the axiom of reducibility is logically necessary is what would be meant by saying that it is true in all possible worlds.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XVII)
     A reaction: This striking remark is a nice bridge between Leibniz (about whom Russell wrote a book) and Kripke.
14. Science / B. Scientific Theories / 1. Scientific Theory
Mathematically expressed propositions are true of the world, but how to interpret them? [Russell]
     Full Idea: We know that certain scientific propositions - often expressed in mathematical symbols - are more or less true of the world, but we are very much at sea as to the interpretation to be put upon the terms which occur in these propositions.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], VI)
     A reaction: Enter essentialism, say I! Russell's remark is pretty understandable in 1919, but I don't think the situation has changed much. The problem of interpretation may be of more interest to philosophers than to physicists.
14. Science / C. Induction / 3. Limits of Induction
From the fact that some men die, we cannot infer that they all do [Philodemus]
     Full Idea: There is no necessary inference, from the fact that men familiar to us die when pierced through the heart, that all men do.
     From: Philodemus (On Signs (damaged) [c.50 BCE], 1.3)
     A reaction: This is scepticism about the logic of induction, long before David Hume. This is said to be a Stoic argument against Epicureans - though on the whole Stoics are not keen on scepticism.
19. Language / D. Propositions / 1. Propositions
Propositions are mainly verbal expressions of true or false, and perhaps also symbolic thoughts [Russell]
     Full Idea: We mean by 'proposition' primarily a form of words which expresses what is either true or false. I say 'primarily' because I do not wish to exclude other than verbal symbols, or even mere thoughts if they have a symbolic character.
     From: Bertrand Russell (Introduction to Mathematical Philosophy [1919], XV)
     A reaction: I like the last bit, as I think of propositions as pre-verbal thoughts, and I am sympathetic to Fodor's 'language of thought' thesis, that there is a system of representations within the brain.
22. Metaethics / A. Ethics Foundations / 1. Nature of Ethics / g. Moral responsibility
Without freedom of will actions lack moral significance [Rousseau]
     Full Idea: If you take away all freedom of the will, you strip a man's actions of all moral significance.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.4)
     A reaction: Rousseau is (in the context) guilty of the basic error of confusing freedom of action with freedom of the will. If the will has scope to act, it has freedom of action; if the will is not contrained in its decision by prior causes, it has freedom of will.
24. Political Theory / A. Basis of a State / 1. A People / b. The natural life
Natural mankind is too fragmented for states of peace, or of war and enmity [Rousseau]
     Full Idea: Men are not naturally enemies, for the simple reason that men living in their original state of independence do not have sufficiently constant relationships among themselves to bring about either a state of peace or a state of war.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.4)
     A reaction: He sees people in a state of nature as more or less solitary, and certainly in groups any more organised than a small family. One might then be in a state of permanent feud, rather than war, but without settlements people can move away.
24. Political Theory / A. Basis of a State / 1. A People / c. A unified people
Rousseau assumes that laws need a people united by custom and tradition [Rousseau, by Wolff,J]
     Full Idea: Rousseau assumes that there should already be bonds of custom and tradition uniting a people before it is fit to receive laws.
     From: report of Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762]) by Jonathan Wolff - An Introduction to Political Philosophy (Rev) 3 'Rousseau'
     A reaction: In unusual circumstances, such as the arrival of a large population at a new colony, it might be that the laws would create the missing customs and traditions.
The act of becoming 'a people' is the real foundation of society [Rousseau]
     Full Idea: The act by which people become 'a people' is the real foundation of society.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.5)
     A reaction: The difficulty with many older countries is that it is impossible to identify such an act. Mythologies are created to fictionalise such acts; in Britain we refer back to King Alfred, and to Magna Carta. I suspect 1660 is the key year.
To overcome obstacles, people must unite their forces into a single unified power [Rousseau]
     Full Idea: Men have no other means of maintaining themselves but to form by aggregation a sum of forces that could gain the upper hand over the resistance of obstacles, so that their forces are directed by means of a single moving power and made to act in concert.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.6)
     A reaction: I prefer the Aristotelian view, that men are naturally gregarious and social (like bees and ants), so this act of solidarity in superfluous. A human people is only broken up by violence or disaster, like kicking over an ants' nest.
Human nature changes among a people, into a moral and partial existence [Rousseau]
     Full Idea: The establisher of a people is in a position to change human nature, to transform each individual into a part of a larger whole from which the individual receives his life and being, to substitute a partial and moral existence for natural independence.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.07)
     A reaction: The 'partial' part is obvious, in the compromises of society, but he says we only become moral in a people, and even more so when that people constitute a state. In the state of nature, morality seems to be unneeded, rather than absent.
24. Political Theory / A. Basis of a State / 2. Population / b. State population
A state must be big enough to preserve itself, but small enough to be governable [Rousseau]
     Full Idea: Like a well-formed man, there are limits to the size a state can have, so as not to be too large to be capable of being well governed, nor too small to be capable of preserving itself on its own.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.09)
     A reaction: Geneva was his model, and it is close to the size of a Greek polis. Presumably even Scotland would be thought ungovernable, never mind the United States. Luxembourg might be his ideal nowadays. Thousands of them!
Too much land is a struggle, producing defensive war; too little makes dependence, and offensive war [Rousseau]
     Full Idea: Too much land makes its defence is onerous, its cultivation inadequate, and its yield surplus, which causes defensive wars. If there is not enough land, the state is at the discretion of its neighbours for what it needs as surplus, causing offensive wars.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.10)
     A reaction: This sounds much too simplistic, like the causes of squabbles in a kindergarten. Certainly inequalities between nations (such as the USA and Mexico) produces frictions. Advances in agriculture technology have transformed this problem.
If the state enlarges, the creators of the general will become less individually powerful [Rousseau]
     Full Idea: The ratio of the sovereign to the subject increases in proportion to the number of citizens. The larger the state becomes, the less liberty there is.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.01)
     A reaction: This is because we remain equally subjected to the state whatever its size, but have less power to influence if there are more citizens. In modern states we all feel pathetically powerless, because of the numbers.
If the population is larger, the government needs to be more powerful [Rousseau]
     Full Idea: In order to be good, the government must be relatively stronger in proportion as the populace is more numerous.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.01)
     A reaction: This could either imply a larger government, or more powerful laws for a fairly small government. Rousseau implies an almost mathematical law (of ratios) which determines the size of the government.
24. Political Theory / A. Basis of a State / 3. Natural Values / a. Natural freedom
Man is born free, and he is everywhere in chains [Rousseau]
     Full Idea: Man is born free, and he is everywhere in chains. Those who think themselves the masters of others are indeed greater slaves than they.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.1)
     A reaction: I've always liked the second sentence, though it may be wishful thinking. It is probably rather fun owning slaves. The idea that man is 'born free' strikes me as nonsense. Man is a highly social animal, which only flourishes if enmeshed in a culture.
No man has any natural authority over his fellows [Rousseau]
     Full Idea: No man has any natural authority over his fellows.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.4)
     A reaction: This is, of course, specifically denying that superior strength is the same as a natural right. 'Right' might be a better word than 'authority'. If strength doesn't bestow a natural right, then presumably neither does weakness.
24. Political Theory / B. Nature of a State / 1. Purpose of a State
A state's purpose is liberty and equality - liberty for strength, and equality for liberty [Rousseau]
     Full Idea: The greatest good and purpose of every legislative system boils down to liberty and equality. Liberty because dependence takes force from the body of the state, and equality because liberty cannot subsist without it.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.11)
     A reaction: The idea of 'taking force' seems to cover the modern welfare state. Rousseau likes robustly self-sufficient citizens. To ensure equality, however, it may be necessary to restrict liberty.
The greatest social good comes down to freedom and equality [Rousseau]
     Full Idea: The greatest good of all, which ought to be the goal of every system of law, comes down to two main objects, freedom and equality.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.11)
     A reaction: He goes on the specify the nature of the equality (Idea 7248). A rival pair of goods might be security and opportunity. On balance, I think I prefer my pair to Rousseau's.
The measure of a successful state is increase in its population [Rousseau]
     Full Idea: The government under which, without external means, without naturalisations, without colonies, the citizens become populous and multiply the most, is infallibly the best government.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.09)
     A reaction: I'm not sure if this was true in the eighteenth century. Birth control has entirely changed the picture, since affluent people seem less inclined to breed. Presumably poverty increased famine and infant mortality.
24. Political Theory / B. Nature of a State / 2. State Legitimacy / a. Sovereignty
The sovereignty does not appoint the leaders [Rousseau]
     Full Idea: The election of leaders is a function of government and not of the sovereignty.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], IV.3)
     A reaction: The point is that the general will only establishes the form of government, and not its content. In Britain we accept leaders who are appointed by their own party, and not by the electorate.
Rousseau insists that popular sovereignty needs a means of expressing consent [Rousseau, by Oksala]
     Full Idea: Rousseau's idea of popular sovereignty is a much more radical idea of self-government, because he insists that the consent of the people has to have a real means of expression.
     From: report of Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762]) by Johanna Oksala - Political Philosophy: all that matters Ch.5
     A reaction: Presumably Hobbes's 'contract' is forgotten in the mists of time, and ceases to be of any interest to a ruler (such as Charles I, who thought God must have appointed him). Perhaps Britain needs an annual ceremony reaffirming the monarch.
Sovereignty is the exercise of the general will, which can never be delegated [Rousseau]
     Full Idea: Since sovereignty is merely the exercise of the general will, it can never be alienated, and the sovereign which is only a collective being, cannot be represented by anything but itself. Power can perfectly well be transmitted, but not the will.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.01)
     A reaction: Part of the post-Hobbesian revolution, which sees sovereignty as residing in the will or consensus of the people, rather than in a divine right, or a right of power. In 2016 this isn't going very well. A people choosing to obey is thereby dissolved.
Just as people control their limbs, the general-will state has total control of its members [Rousseau]
     Full Idea: Just as nature gives each man an absolute power over all of his members, the social compact gives the body politic an absolute over all its members, which is the power directed by the general will, and bearing the name sovereignty.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.04)
     A reaction: A highly organic view of the state, and his favourite political metaphor. Does the metaphor include disease and madness? In the 1930s Germany went insane. The man may be happy, but are his limbs happy? If I burn my hand? Etc.
Political laws are fundamental, as they firmly organise the state - but they could still be changed [Rousseau]
     Full Idea: The laws regulating the relationship of the sovereign to the state are political laws, which are also fundamental. There is one way of organising a state, and people should stand by it. ...But a people is always in a position to change its laws.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.12)
     A reaction: Constitutions take on a sacred and inviolable quality, but Rousseau clearly thinks 'the Sabbath is made for man'. I think the USA is crazy not to change its constitution on the subject of bearing arms.
24. Political Theory / B. Nature of a State / 2. State Legitimacy / b. Natural authority
Force can only dominate if it is seen as a right, and obedience as a duty [Rousseau]
     Full Idea: The strongest is never strong enough to be master all the time, unless he transforms force into right and obedience into duty.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.3)
     A reaction: Presumably the people only accept force as a right and obedience as a duty if they appear to be in the people's interests - because the alternative looks worse. In other words, they are terrified.
24. Political Theory / B. Nature of a State / 2. State Legitimacy / c. Social contract
The social order is a sacred right, but based on covenants, not nature [Rousseau]
     Full Idea: The social order is a sacred right which serves as a basis for all other rights; and as it is not a natural right, it must be one founded on covenants.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.1)
     A reaction: I think Rousseau is offering a contradiction here, when he suggests we have a 'sacred' right, which is nevertheless only based on 'covenants'. You can't have it both ways. This is an abuse of the word 'sacred'.
The government is instituted by a law, not by a contract [Rousseau]
     Full Idea: The act that institutes the government is not a contract but a law.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.18)
     A reaction: This is a law which implements the general will. There is nothing for citizens to make a contract with, since the sovereign is an abstraction, whereas a social contract is made between actual people. I like Rousseau's big idea.
24. Political Theory / B. Nature of a State / 2. State Legitimacy / d. General will
The social pact is the total subjection of individuals to the general will [Rousseau]
     Full Idea: The essence of the social pact is that 'each one of us puts into the community his person and all his powers under the supreme direction of the general will; and as a body, we incorporate every member as an indivisible part of the whole'.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.6)
     A reaction: This is alarmingly like totally subjecting yourself to the 'Will of God', where the big problem is a bunch of priests (or worse) insisting that they know better than you do what that Will consists of. I have no idea what the current Will of Britain is.
We need a protective association which unites forces, but retains individual freedom [Rousseau]
     Full Idea: The problem is to find a form of association which protects with all common forces the person and goods of each associate, by means of which each one, while uniting with all, nevertheless obeys only himself and remains as free as before.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.6)
     A reaction: This is the clear purpose of Rousseau's famous concept of the General Will. The idea is that you submit to the general will because you helped formulate it, so you remain free. It is a lovely idea, but notoriously difficult to implement.
To foreign powers a state is seen as a simple individual [Rousseau]
     Full Idea: In relation to a foreign power, the body politic is a simple entity, an individual.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.7)
     A reaction: This is strikingly contrary to the spirit of liberalism, in which I may be appalled by the foreign policy of my own government, and protest strongly against it. Rousseau might be considered as freedom's greatest champion, and greatest enemy!
The act of association commits citizens to the state, and the state to its citizens [Rousseau]
     Full Idea: The act of association is a reciprocal commitment of public and private individuals, and each individual, contracting with himself, is under a twofold commitment, as a member of the sovereign to individuals, and as a member of the state to the sovereign.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.7)
     A reaction: This seems to be expressed in modern terms as a mutual entailment of rights and duties. Where the traditional social contract is just between individuals, this seems to be a contract with a unified abstraction, of state commitment to citizens.
Citizens must ultimately for forced to accept the general will (so freedom is compulsory!) [Rousseau]
     Full Idea: To avoid the general compact being an empty formula, it tacitly entails the commitment that whoever refuses to obey the general will will be forced to do so by the entire body. This means merely that he will be forced to be free.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.7)
     A reaction: Rousseau obviously enjoyed this paradox (which sounds like US foreign policy). Apart from anarchism, any political system will need a bit of force to back it up. Should democratic voting becoming compulsory, if the turnout declines too far?
Individual citizens still retain a private will, which may be contrary to the general will [Rousseau]
     Full Idea: Each individual can, as a man, have a private will contrary to or different from the general will that he has as a citizen. His private interest can speak to him in an entirely different manner than the common interest.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.7)
     A reaction: So why I accept the general will when these two clash (apart from threat of punishment - which may be capital if I am recalcitrant!)? Usually the general will is also for my good - but not always. Idealist love of the people?
The general will is common interest; the will of all is the sum of individual desires [Rousseau]
     Full Idea: The general will studies only common interest, while the will of all studies private interest, and is indeed no more than the sum of individual desires.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.03)
     A reaction: This invites the obvious liberal response (given later by utilitarians: Idea 3778) that there can be no more to any great 'will' than the sum of the individuals (which leads to Margaret Thatcher's famous 'there is no such thing as society').
The general will is always right, but the will of all can err, because it includes private interests [Rousseau]
     Full Idea: The general will is always right. ....There is often a great deal of difference between the will of all and the general will. The latter considers only the general interest, but the former considers private interest and is merely the sum of private wills.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.03)
     A reaction: Hence in order to get an expression of the general will, voters must exclusively focus on the general good. I do that in general elections, only to find that the people around me vote for their own interests. I wish we all did the same thing.
If the state contains associations there are fewer opinions, undermining the general will [Rousseau]
     Full Idea: If there are partial association in the state ...there are no longer as many voters as there are men, but merely as many as there are associations. The differences become less numerous and yield a result that is less general.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.03)
     A reaction: This appears to entirely reject political parties, and similar groups, which he had seen forming in England. It goes with his interesting faith that the more separate views there are, the more the right choice will emerge.
If a large knowledgeable population votes in isolation, their many choices will have good results [Rousseau]
     Full Idea: If, when a sufficiently informed populace deliberates, the citizens were to have no communication among themselves, the general will would always result from a large number of small differences, and the deliberations would always be good.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.03)
     A reaction: An obvious weak point in the electorate being well informed, if someone controls the sources of information. All the optimism of the Enlightenment is in this idea - that rational beings converge of the truth. All pubs closed in the month of an election?
The general will changes its nature when it focuses on particulars [Rousseau]
     Full Idea: Just as a private will cannot represent the general will, the general will, for its part, alters its nature when it has a particular object.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.04)
     A reaction: Is the general will, then, in danger of being much too general, because as soon as it gets close to anything practical it becomes distorted. It can design the constitution, but can it give a view on capital punishment, or is that too personal?
The general will is always good, but sometimes misunderstood [Rousseau]
     Full Idea: By themselves the people always will what is good, but by themselves they do not always discern it.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.06)
     A reaction: This sounds like a can of worms. It invites someone to step in as interpreter - a spin doctor, perhaps, or a newspaper proprietor. The first proposition strikes me as absurdly optimistic. Think of the people of Europe in August 1914.
Laws are authentic acts of the general will [Rousseau]
     Full Idea: The laws are nothing other than the authentic acts of the general will.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.12)
     A reaction: I wonder how you tell whether an act of the general will is 'authentic'? Nevertheless, in a modern democracy there seems a lot of truth in it; when controversial legislation is in the offing, governments have to be very attentive to the people.
Assemblies must always confirm the form of government, and the current administration [Rousseau]
     Full Idea: The opening of assemblies, which solely aim to preserve the social treaty, should always start with two separate propositions: 1) does it please the sovereign to preserve the present form of government?, 2) ...and to preserve the present administration?
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.18)
     A reaction: I would love it if the British people were allowed to discuss our form of government, but it now seems completely ossified. Being a monarchy, with the consequent patronage, almost guarantees this stasis.
The more unanimous the assembly, the stronger the general will becomes [Rousseau]
     Full Idea: The more harmony reigns in the assemblies, that is to say, the closer opinions come to unanimity, the more dominant too is the general will.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], IV.2)
     A reaction: This seems important, because the general will comes in degrees. A decision from the assembly would come with an index number indicating its strength. His dream is obviously to get close to unanimity on all decisions. Maybe! Brexit 52%!
24. Political Theory / B. Nature of a State / 4. Citizenship
Citizens should be independent of each other, and very dependent on the state [Rousseau]
     Full Idea: Each citizen should be perfectly independent of all the others and excessively dependent on the city.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.12)
     A reaction: Unlike many other of his pronouncements, this sounds a bit like a welfare state, though I doubt if he means that. Rousseau's state, founded by the general will, seems to have a quasi-religious quality, like a devotee's love of God.
A citizen is a subject who is also sovereign [Rousseau]
     Full Idea: The words 'subject' and 'sovereign' are identical correlatives, whose meaning is combined in the single word 'citizen'.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.13)
     A reaction: 'Citizen' was the favourite post-revolutionary label, probably based on this remark. I've heard foreigners tease Britons for being 'subjects' of the monarch, where they are pure citizens. But we are all subject to the law, made by others.
24. Political Theory / B. Nature of a State / 5. Culture
The flourishing of arts and letters is too much admired [Rousseau]
     Full Idea: Times in which letters and arts are known to have flourished have been admired too much.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.09 n9)
     A reaction: I assume most marxists would agree with this thought. Eighteenth century France is a good candidate for this judgement. The arts always needed patronage.
24. Political Theory / C. Ruling a State / 2. Leaders / b. Monarchy
Ancient monarchs were kings of peoples; modern monarchs more cleverly rule a land [Rousseau]
     Full Idea: Ancient monarchs called themselves King of the Persians or Scythians, regarding themselve merely as the leaders of men. Today's monarchs more shrewdly call themselves King of France or England. By holding the land, they are sure of the inhabitants.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.9)
     A reaction: This matches the Germans being earlier defined by speaking the language, and now defined by a territory. It is more to do with the rise of the modern state than to do with the shrewdness of the monarchs.
The highest officers under a monarchy are normally useless; the public could choose much better [Rousseau]
     Full Idea: Those who attain the highest positions in monarchies are most often petty bunglers, swindlers and intriguers, whose talents serve only to display their incompetence to the public. The populace is much less often in error in its choice than the prince.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.06)
     A reaction: Many monarchs have had famously good advisers, such as Lord Burleigh. The worst thing about bad leaders, at any level, is the bad appointments they make.
Hereditary monarchy is easier, but can lead to dreadful monarchs [Rousseau]
     Full Idea: Some crowns are hereditary. So by substituting the disadvantage of regencies for elections, an apparent tranquillity has been preferred to a wise election, the risk of having children, monsters or imbeciles for leaders is preferred to choosing good kings.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.06)
     A reaction: Henry VI is the prime English example. The regents feuded, and then when he grew up it became obvious that he was hopeless. How many English monarchs would have been elected? But we would have missed Good Queen Bess.
Attempts to train future kings don't usually work, and the best have been unprepared [Rousseau]
     Full Idea: A great deal of effort is made to teach young princes the art of ruling. It does not appear that this education does them any good. It would be better to teach them the art of obeying. The most celebrated kings were not brought up to reign.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.06)
     A reaction: King Alfred is our prime example of a success, But if only we had had Charles I's late brother Henry, instead the untrained Charles.
24. Political Theory / C. Ruling a State / 2. Leaders / d. Elites
Natural aristocracy is primitive, and hereditary is dreadful, but elective aristocracy is best [Rousseau]
     Full Idea: There are three sorts of aristocracy: natural, elective, and hereditary. The first is suited only to simple people; the third is the worst of any government. The second is the best; it is aristocracy properly so-called.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.05)
     A reaction: This seems like the modern idea of 'meritocracy'. The Chinese civil service exams, introduced into Europe in the nineteenth century.
Natural aristocracy is primitive, hereditary is bad, and elective aristocracy is the best [Rousseau]
     Full Idea: There are three types of aristocracy, natural, elective and hereditary. The first is suited only to primitive peoples; the third is the worst of all governments; the second is the best, and this is aristocracy in the true sense of the word.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.05)
     A reaction: Presumably he means what we call 'meritocracy', and it seems a bit optimistic to hope that democracy will deliver that. I don't think Plato would expect a democracy to elect his Guardians.
Large states need a nobility to fill the gap between a single prince and the people [Rousseau]
     Full Idea: With a large state in the hands of one man there is too great a distance between the prince and the people, and the state lacks cohesiveness. This requires intermediate orders of nobility to fill them. A small state is ruined by all these social levels.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.06)
     A reaction: [compressed] This seems to be a justification for the French ancien regime. Presumably this bit was not quoted much in 1789. Why must the gap be filled by 'nobility'? What about an elected house of lords?
24. Political Theory / C. Ruling a State / 3. Government / a. Government
Law makers and law implementers should be separate [Rousseau]
     Full Idea: It is not good for the one who makes the laws to execute them.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.04)
     A reaction: He doesn't give his reasons here, but this piece of wisdom is widely supported. There is a problem when the executive find themselves trying to enforce bad, discredited laws. Maybe the police know best what the law should say? Or not!
The state has a legislature and an executive, just like the will and physical power in a person [Rousseau]
     Full Idea: Every free action has a moral cause, the will, and a physical cause, the power to act. ...The body politic has the same moving causes, namely the legislative power, and executive power. Nothing should be done without their concurrence.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.01)
     A reaction: [compressed] This terminology is now standard in political philosophy. An absolute monarch like Edward III presumably embodies both branches.
24. Political Theory / C. Ruling a State / 3. Government / c. Executive
I call the executive power the 'government', which is the 'prince' - a single person, or a group [Rousseau]
     Full Idea: I call 'government' or supreme administration the legitimate exercise of executive power; I call 'prince' or magistrate the man or body charged with that administration.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.01)
     A reaction: Whether the prince is one person or many is left up to the legislative body, which is the general will. Rousseau has no view on the matter.
24. Political Theory / C. Ruling a State / 3. Government / d. Size of government
Large populations needs stronger control, which means power should be concentrated [Rousseau]
     Full Idea: The government becomes slack as the magistrates are multiplied, and the more numerous the people the greater should be the increase of repressive force - ...so the number of leaders should decrease in proportion to the increase of the number of people.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.02)
     A reaction: This bit sounds Stalinist! A vast population seems to require a dictator. When his state is Geneva-sized Rousseau seems comfortable, but his plans for bigger states are a bit disturbing.
Democracy for small states, aristocracy for intermediate, monarchy for large [Rousseau]
     Full Idea: Democratic government is suited to small states, aristocratic government to states of intermediate size, and monarchical government to large ones.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.03)
     A reaction: Is he thinking of France for the large state? What would he have made of 1789? Does this progression go on to increase the power of the monarch as the state gets even larger, into dictatorship?
24. Political Theory / C. Ruling a State / 4. Changing the State / c. Revolution
If inhabitants are widely dispersed, organising a revolt is much more difficult [Rousseau]
     Full Idea: The greater the area occupied by the same number of inhabitants, the more difficult it becomes to revolt, since concerted action cannot be taken promptly and secretly.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.09)
     A reaction: Revolutions since then have all occurred in large cities, which have become huge. The dispersal of the rest of the population (as in Russia) doesn't matter.
The state is not bound to leave civil authority to its leaders [Rousseau]
     Full Idea: The state is no more bound to leave civil authority to its leaders than it is to leave military authority to its generals.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.18)
     A reaction: He assumes that a meeting of the citizens can articulate a new expression of the general will, but this idea also endorses revolution, if the prince or magistrates refuse to call this national AGM.
24. Political Theory / D. Ideologies / 5. Democracy / a. Nature of democracy
If the sovereign entrusts government to at least half the citizens, that is 'democracy' [Rousseau]
     Full Idea: The sovereign can entrust the government to the entire people or to the majority of them. This is given the name 'democracy'.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.03)
     A reaction: Note that democracy is here a form for the executive, not for the legislature. I take it that the general will must come close to unanimity, and a mere 51% support for fundamental legislation would never do. Increase the percentage with the importance?
24. Political Theory / D. Ideologies / 5. Democracy / b. Consultation
Democratic elections are dangerous intervals in government [Rousseau]
     Full Idea: Elections leave dangerous intervals and are stormy.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.06)
     A reaction: American presidential elections partially paralyse government for about nine months. In a settled democracy the process of election seems OK. The immediate aftermath can be worse. Losers may refuse to accept the result.
Silence of the people implies their consent [Rousseau]
     Full Idea: The silence of the people permits the assumption that the people consents.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.01)
     A reaction: This seems to me a crucial principle for a democracy, because it says that the democratic way of life is much more than elections. Each citizen has a duty to bravely speak out; the more citizens willing to do this, the less bravery is required.
24. Political Theory / D. Ideologies / 5. Democracy / d. Representative democracy
The English are actually slaves in between elections [Rousseau]
     Full Idea: The English people believes itself to be free; it is gravely mistaken; it is free only during the election of Members of Parliament; as soon as the Members are elected, the people is enslaved.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.15)
     A reaction: Rousseau seems to be hoping for some sort of direct democracy. We could probably set up a direct democracy, by implementing regular voting over the internet, but I doubt if Rousseau would like that either. I certainly wouldn't.
24. Political Theory / D. Ideologies / 5. Democracy / e. Democratic minorities
Minorities only accept majority-voting because of a prior unanimous agreement [Rousseau]
     Full Idea: If there were no earlier agreement, how could there be any obligation on the minority to accept the decision of the majority? The law of majority-voting rests on a covenant, implying at least one previous occasion of unanimity.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.5)
     A reaction: In Britain this points to the Reform Acts of 1832 onwards as crucial. However, whenever democracy is newly introduced into a country (Iraq being a current spectacular case) there is usually a minority opposed to it, who are forcibly overruled.
24. Political Theory / D. Ideologies / 5. Democracy / f. Against democracy
Democracy leads to internal strife, as people struggle to maintain or change ways of ruling [Rousseau]
     Full Idea: No government is so subject to civil wars and internal agitations as a democratic or popular one, since there is none that tends so forcefully and continuously to change its form, or that demands greater vigilance and courage to keep its form.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.05)
     A reaction: We would like to think that a robust democracy, with a free press, can cope with all this strife and still survive. He may be thinking of the English Civil War. Democracies seem to be more conservative about the structure of government.
When ministers change the state changes, because they always reverse policies [Rousseau]
     Full Idea: Each revolution in the ministry produces a revolution in the state, since the maxim common to all ministers and nearly all kings is to do the reverse of their predecessor in everything.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.06)
     A reaction: Most parents bring up their children by trying to correct mistakes their own parents made. British democracy is rife with this desperate need for a new government to make its mark, because they want to win the next election.
24. Political Theory / D. Ideologies / 10. Theocracy
In early theocracies the god was the king, and there were as many gods as nations [Rousseau]
     Full Idea: At first men had no other kings but gods, and no other government than a theocratic one. ....By the mere fact that a god was placed at the head of every political society, it followed that there were as many gods as there were peoples.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], IV.8)
     A reaction: He must be thinking of the Old Testament histories here. (see Spinoza on that!). He says that the modern idea that these were all really the same god is ridiculous.
25. Social Practice / A. Freedoms / 1. Slavery
Sometimes full liberty is only possible at the expense of some complete enslavement [Rousseau]
     Full Idea: There are some unfortunate circumstances where one's liberty can be preserved only at the expense of someone else's, and where the citizen can be perfectly free only if the slave is completely enslaved. Such was the situation in Sparta.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.15)
     A reaction: Rousseau wrote just before the moment when it was seen that slavery in European empires might be abolished, but he was not in the forefront of thought on this one. Greek philosophy would probably never have happened without slavery.
We can never assume that the son of a slave is a slave [Rousseau]
     Full Idea: To decide that the son of a slave is born a slave is to decide that he is not a man.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], IV.2)
     A reaction: Obviously this is because men are 'born free', though I am not clear how that maxim can be reached. I take it for granted that African slaves in the Americas found themselves born into slavery. No justification was required.
25. Social Practice / A. Freedoms / 5. Freedom of lifestyle
Appetite alone is slavery, and self-prescribed laws are freedom [Rousseau]
     Full Idea: To be governed by appetite alone is slavery, while obedience to a law one prescribes to oneself is freedom.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.8)
     A reaction: An interesting formulation, sitting somewhere between Aristotle and Kant. The problem is to find a metaethic which will justify the prescription and nature of the self-imposed law.
25. Social Practice / B. Equalities / 1. Grounds of equality
The social compact imposes conventional equality of rights on people who may start unequally [Rousseau]
     Full Idea: Instead of destroying natural equality, the fundamental compact substitutes a moral and legitimate equality to any natural physical inequality. ...so that men all become equal by convention and by right.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.9)
     A reaction: This does not pretend that equality is a natural right. The imposition of equality is virtually the main point of forming a state. Effectively, the state operates like an insurance company, treating all contributors as equal.
25. Social Practice / B. Equalities / 4. Economic equality
No citizen should be rich enough to buy another, and none so poor as forced to sell himself [Rousseau]
     Full Idea: Where wealth is concerned, no citizen should be rich enough to buy another, and none should be so poor as to be forced to sell himself.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.11)
     A reaction: Rousseau is thinking of slavery, but this also points to prostitution as a key indicator of social equality. In Victorian Britain it seems that extensive prostituion was unavoidable; nowadays it looks more like a voluntary choice (for indigenous Britons).
25. Social Practice / C. Rights / 3. Alienating rights
If we all give up all of our rights together to the community, we will always support one another [Rousseau]
     Full Idea: The social compact reduces to a single clause, namely the total alienation of each associate, together with all of his rights, to the entire community. Since this condition is equal for everyone, no one has an interest in making it burdensome for others.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.6)
     A reaction: He speaks elsewhere of basic natural rights which can never be alienated, such as self-defence. It is what small groups do all the time, if they start off as equals. Difficult to manage with large groups. Factions are the problem.
In society man loses natural liberty, but gains a right to civil liberty and property [Rousseau]
     Full Idea: What man loses by the social contract is his natural liberty and the absolute right to anything that tempts him; what he gains is civil liberty and the legal rights of propery in what he possesses.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.8)
     A reaction: It is an appealing idea that the purpose of society is to increase liberty, not to restrict it. That, on the whole, is my view. American libertarianism opens up the world to gun crime, vigilantes, pornographers and bounty-hunters.
We alienate to society only what society needs - but society judges that, not us [Rousseau]
     Full Idea: Each person alienates, by the social compact, only that portion of his power, his goods, and liberty whose use is of consequence to the community; but we must also grant that only the sovereign is the judge of what is of consequence.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.04)
     A reaction: The weakness here is how society sees its needs. He seems to assume that two societies will arrive at almost identical general wills, but Spartans, Prussians and Serbs may require the lives of your children for the state.
25. Social Practice / C. Rights / 4. Property rights
Private property must always be subordinate to ownership by the whole community [Rousseau]
     Full Idea: Each private individual's right to his very own store is always subordinate to the community's right to all, without which there could be neither solidity in the social fabric nor real force in the exercise of sovereignty.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.9)
     A reaction: This may sound a bit drastic, but every country practices this principle, seen in compulsory purchase orders (e.g. to build a railway line). In liberal democracies you expect good compensation. In communist Roumania you were just moved. Also taxation.
25. Social Practice / D. Justice / 2. The Law / a. Legal system
The state ensures liberty, so civil law separates citizens, and binds them to the state [Rousseau]
     Full Idea: The relationship of members to each other should be as small as possible, and as large as possible to the entire body. ...Only the force of the state brings about the liberty of its members. From this relationship civil laws arise.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.12)
     A reaction: I'm guessing that these laws could be said mainly to prescribe both our rights and our duties. His four types of law are political, civil, criminal, and customary.
25. Social Practice / D. Justice / 2. The Law / c. Natural law
Natural justice, without sanctions, benefits the wicked, who exploit it [Rousseau]
     Full Idea: The laws of natural justice, lacking any natural sanctions, are unavailing among men. In fact, such laws merely benefit the wicked and injure the just, since the just respect them while others do not do so in return.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.06)
     A reaction: This seems a very accurate observation, and points us towards either contracts, or a justification of the use of force by good people.
25. Social Practice / D. Justice / 3. Punishment / a. Right to punish
We accept the death penalty to prevent assassinations, so we must submit to it if necessary [Rousseau]
     Full Idea: Whoever wills the end also wills the means. ...The death penalty inflicted on criminals can be viewed from more or less this point of view. It is in order to avoid being the victim of an assassin that a person consents to die, were he to become one.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.05)
     A reaction: This seems to be roughly the spirit in which Socrates submitted to his death. I doubt whether many criminals agree with harsh punishments dished out to other criminals who get caught.
A trial proves that a criminal has broken the social treaty, and is no longer a member of the state [Rousseau]
     Full Idea: The legal proceeding and judgement are the proofs and the declaration that a criminal has broken the social treaty, and consequently that he is no longer a member of the state.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.05)
     A reaction: This seems to be a plausible rationalisation of capital punishment, but what about lesser crimes. Is the interior of a prison a sort of temporary exile from the state? Hence the significance of whether prisoners are allowed to vote. But 19811.
25. Social Practice / D. Justice / 3. Punishment / c. Deterrence of crime
Only people who are actually dangerous should be executed, even as an example [Rousseau]
     Full Idea: There is no wicked man who could not be made good for something. One has the right to put to death, even as an example, only someone who cannot be preserved without danger.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], II.05)
     A reaction: This formulation implies that we could execute a dangerous person as a deterrent, even though they were not guilty of this particular crime. I suspect that Rousseau was too nice to go through with that.
25. Social Practice / E. Policies / 1. War / b. Justice in war
War gives no right to inflict more destruction than is necessary for victory [Rousseau]
     Full Idea: War gives no right to inflict any more destruction than is necessary for victory.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], I.4)
     A reaction: This is the principle at stake in discussion of the bombing of Germany in 1942-5. We all seem to agree with this principle, and are shocked by breaches of it, but I am not sure why. Destruction must be a fundamentally bad thing - a basic value.
25. Social Practice / E. Policies / 1. War / c. Combatants
Wars are between States, not people, and the individuals are enemies by accident [Rousseau]
     Full Idea: War is something that occurs not between man and man, but between States. The individuals who become involved in it are enemies only by accident. A State can have as its enemies only other States, not men at all.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], p.249), quoted by Jeff McMahan - Killing in War 2.5
     A reaction: This is the classic statement of the collectivist view, which goes on to assert that the morality of warfare is quite different from ordinary morality. McMahan argues against this view, very persuasively.
25. Social Practice / E. Policies / 2. Religion in Society
By separating theological and political systems, Jesus caused divisions in the state [Rousseau]
     Full Idea: In separating the theological system from the political system, Jesus made the state to cease being united and caused internal divisions. Since this new idea of an otherwordly kingdom had never entered the heads of pagans, they saw Christians as rebels.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], IV.8)
     A reaction: This is the sort of stuff that made Rousseau a vast number of enemies, which embittered him. It is the sort of cool assessment which became commonplace in Germany sixty year later.
Civil religion needs one supreme god, an afterlife, justice, and the sanctity of the social contract [Rousseau]
     Full Idea: Dogmas of civil religion should be simple. The existence of a powerful, intelligent, beneficent divinity that foresees and provides; the life to come; the happiness of the just; the punishment of the wicked; the sanctity of the social contract and laws.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], IV.8)
     A reaction: Notice that he gratuitously makes the social contract sacred (even though it can be voluntarily abandoned, and the general will can be changed). Presumably the foundation of any society, such as the ballot box, has to be sacred.
All religions should be tolerated, if they tolerate each other, and support citizenship [Rousseau]
     Full Idea: Tolerance should be shown to all religions which tolerate other religions, so long as their dogmas contain nothing contrary to the duties of a citizen.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], IV.8)
     A reaction: Quite a good guideline for the attitude of western countries to middle eastern religious practices which arrive in their midst. Rousseau says the state has a minimal core religion (Idea 19852), which thus tolerates most other religions.
Every society has a religion as its base [Rousseau]
     Full Idea: No state has ever been founded without religion serving as its base.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], IV.8)
     A reaction: It is not clear to me that the ancient Greek cities had religion as a 'base', though they all had a religion, and expected conformity. Religion doesn't figure much in Thucydides. Communist Russia was the first explicitly atheist state, I think.
25. Social Practice / E. Policies / 4. Taxation
The amount of taxation doesn't matter, if it quickly circulates back to the citizens [Rousseau]
     Full Idea: It is not on the basis of the amount of taxation that the burden is measured, but on the basis of the path they have to travel in order to return to the hands from which they came. If circulation is prompt and regular, the amount one pays is unimportant.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], III.08)
     A reaction: So the problem is when the government wants to build up a surplus, or pay off debts (or is corrupt, or even if it is suspected of corruption).
29. Religion / B. Monotheistic Religion / 4. Christianity / a. Christianity
A tyrant exploits Christians because they don't value this life, and are made to be slaves [Rousseau]
     Full Idea: The Christian spirit is too favourable to tyranny for tyranny not to take advantage of it. True Christians are made to be slaves; they know it and hardly care; this short life has too little value in their eyes.
     From: Jean-Jacques Rousseau (The Social Contract (tr Cress) [1762], IV.8)
     A reaction: This is strikingly close to Nietzsche's verdict on Christianity, that it is the essence of slave morality. It has certainly been my experience that Christians tend to be much more reluctant than other people to stand up to authority.
