102 ideas
| 18330 | Judging by the positive forces, the Renaissance was the last great age [Nietzsche] |
| Full Idea: Ages are to be assessed by their positive forces - and by this assessment the age of the Renaissance, so prodigal and so fateful, appears as the last great age. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.37) | |
| A reaction: I suspect that Nietzsche places art very high among the positive forces. Science and technology showed barely a glimmer during the Renaissance. Mathematics moved very little, Copernicus was ignored, and logic was static. |
| 2900 | I revere Heraclitus [Nietzsche] |
| Full Idea: I set apart with high reverence the name of Heraclitus. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.2) |
| 2913 | Thucydides was the perfect anti-platonist sophist [Nietzsche] |
| Full Idea: My recreation, my preference, my cure from all Platonism has always been Thucydides. …Sophist culture, by which I mean realist culture, attains in him its perfect expression. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 9.2) |
| 2909 | Thinking has to be learned in the way dancing has to be learned [Nietzsche] |
| Full Idea: Thinking has to be learned in the way dancing has to be learned. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 7.7) | |
| A reaction: Nice. At its deepest level thinking isn't a rational process? |
| 2892 | Wanting a system in philosophy is a lack of integrity [Nietzsche] |
| Full Idea: I mistrust all systematizers and avoid them. The will to system is a lack of integrity. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], Maxim 26) |
| 2896 | I want to understand the Socratic idea that 'reason equals virtue equals happiness' [Nietzsche] |
| Full Idea: I seek to understand out of what idiosyncrasy that Socratic equation 'reason equals virtue equals happiness' derives. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.04) |
| 2897 | With dialectics the rabble gets on top [Nietzsche] |
| Full Idea: With dialectics the rabble gets on top. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.05) |
| 2898 | Anything which must first be proved is of little value [Nietzsche] |
| Full Idea: What has first to have itself proved is of little value. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.05) |
| 8625 | What physical facts could underlie 0 or 1, or very large numbers? [Frege on Mill] |
| Full Idea: What in the world can be the observed fact, or the physical fact, which is asserted in the definition of the number 777864? ...What a pity that Mill did not also illustrate the physical facts underlying the numbers 0 and 1! | |
| From: comment on John Stuart Mill (System of Logic [1843]) by Gottlob Frege - Grundlagen der Arithmetik (Foundations) §7 | |
| A reaction: I still think patterns could be an empirical foundation for arithmetic, though you still have to grasp the abstract concept of the pattern. An innate capacity to spot resemblance gets you a long way. |
| 17895 | Combining two distinct assertions does not necessarily lead to a single 'complex proposition' [Mill] |
| Full Idea: In 'Caesar is dead, and Brutus is alive' ...there are here two distinct assertions; and we might as well call a street a complex house, as these two propositions a complex proposition. | |
| From: John Stuart Mill (System of Logic [1843], 1.04.3) | |
| A reaction: Arthur Prior, in his article on 'tonk', cites this to claim that the mere account of the and-introduction rule does not guarantee the existence of any conjunctive proposition that can result from it. Mill says you are adding a third proposition. |
| 10427 | All names are names of something, real or imaginary [Mill] |
| Full Idea: All names are names of something, real or imaginary. | |
| From: John Stuart Mill (System of Logic [1843], p.32), quoted by Mark Sainsbury - The Essence of Reference 18.2 | |
| A reaction: Mill's example of of being like a chalk mark on a door, but Sainsbury points out that names can be detached from bearers in a way that chalk marks can't. |
| 4944 | Mill says names have denotation but not connotation [Mill, by Kripke] |
| Full Idea: It is a well known doctrine of Mill that names have denotation but not connotation. | |
| From: report of John Stuart Mill (System of Logic [1843]) by Saul A. Kripke - Naming and Necessity lectures Lecture 1 | |
| A reaction: A nice starting point for any discussion of the topic. The obvious response is that a name like 'Attila the Hun' seems to have a very vague denotation for most of us, but a rather powerful connotation. |
| 7762 | Proper names are just labels for persons or objects, and the meaning is the object [Mill, by Lycan] |
| Full Idea: Mill seemed to defend the view that proper names are merely labels for individual persons or objects, and contribute no more than those individuals themselves to the meanings of sentences in which they occur. | |
| From: report of John Stuart Mill (System of Logic [1843]) by William Lycan - Philosophy of Language | |
| A reaction: Identity statements can become trivial on this view ('Twain is Clemens'). Modern views have become more sympathetic to Mill, since externalism places meanings outside the head of the speaker. |
| 9801 | Numbers must be assumed to have identical units, as horses are equalised in 'horse-power' [Mill] |
| Full Idea: There is one hypothetical element in the basis of arithmetic, without which none of it would be true: all the numbers are numbers of the same or of equal units. When we talk of forty horse-power, we assume all horses are of equal strength. | |
| From: John Stuart Mill (System of Logic [1843], 2.6.3) | |
| A reaction: Of course, horses are not all of equal strength, so there is a problem here for your hard-line empiricist. Mill needs processes of idealisation and abstraction before his empirical arithmetic can get off the ground. |
| 8742 | The only axioms needed are for equality, addition, and successive numbers [Mill, by Shapiro] |
| Full Idea: Mill says arithmetic has two axioms, that 'things which are equal to the same thing are equal to each other', and 'equals added to equals make equal sums', plus a definition for each numeral as 'formed by the addition of a unit to the previous number'. | |
| From: report of John Stuart Mill (System of Logic [1843], p.610?) by Stewart Shapiro - Thinking About Mathematics 4.3 | |
| A reaction: The difficulty here seems to be the definition of 1, and (even worse for an empiricist), of 0. Then he may have a little trouble when he reaches infinity. |
| 9800 | Arithmetic is based on definitions, and Sums of equals are equal, and Differences of equals are equal [Mill] |
| Full Idea: The inductions of arithmetic are based on so-called definitions (such as '2 and 1 are three'), and on two axioms: The sums of equals are equal, The differences of equals are equal. | |
| From: John Stuart Mill (System of Logic [1843], 2.6.3) | |
| A reaction: These are axioms for arithmetical operations, rather than for numbers themselves (which, for Mill, do not require axioms as they are empirically derived). |
| 5201 | Mill says logic and maths is induction based on a very large number of instances [Mill, by Ayer] |
| Full Idea: Mill maintained that the truths of logic and mathematics are not necessary or certain, by saying these propositions are inductive generalisations based on an extremely large number of instances. | |
| From: report of John Stuart Mill (System of Logic [1843]) by A.J. Ayer - Language,Truth and Logic Ch.4 | |
| A reaction: Ayer asserts that they are necessary (but only because they are tautological). I like the idea that maths is the 'science of patterns', but that might lead from an empirical start to a rationalist belief in a priori synthetic truths. |
| 9360 | If two black and two white objects in practice produced five, what colour is the fifth one? [Lewis,CI on Mill] |
| Full Idea: If Mill has a demon who, every time two things are brought together with two other things, always introduces a fifth, then if two black marbles and two white ones are put in an urn, the demon could choose his color, but there would be more of one colour. | |
| From: comment on John Stuart Mill (System of Logic [1843]) by C.I. Lewis - A Pragmatic Conception of the A Priori p.367 | |
| A reaction: Nice to see philosophers fighting back against demons. This is a lovely argument against the absurdity of thinking that experience could ever controvert a priori knowledge (though Lewis is no great fan of the latter). |
| 9888 | Mill mistakes particular applications as integral to arithmetic, instead of general patterns [Dummett on Mill] |
| Full Idea: Mill's mistake is taking particular applications as integral to the sense of arithmetical propositions. But what is integral to arithmetic is the general principle that explains its applicability, and determines the pattern of particular applications. | |
| From: comment on John Stuart Mill (System of Logic [1843], 2.6) by Michael Dummett - Frege philosophy of mathematics Ch.20 | |
| A reaction: [Dummett is summarising Frege's view] Sounds like a tidy objection, but you still have to connect the general principles and patterns to the physical world. 'Structure' could be the magic word to achieve this. |
| 9794 | There are no such things as numbers in the abstract [Mill] |
| Full Idea: There are no such things as numbers in the abstract. | |
| From: John Stuart Mill (System of Logic [1843], 2.6.2) | |
| A reaction: Depends. Would we want to say that 'horses don't exist' (although each individual horse does exist)? It sounds odd to say of an idea that it doesn't exist, when you are currently thinking about it. I am, however, sympathetic to Mill. |
| 9796 | Things possess the properties of numbers, as quantity, and as countable parts [Mill] |
| Full Idea: All things possess quantity; consist of parts which can be numbered; and in that character possess all the properties which are called properties of numbers. | |
| From: John Stuart Mill (System of Logic [1843], 2.6.2) | |
| A reaction: Here Mill is skating on the very thinnest of ice, and I find myself reluctantly siding with Frege. It is a very optimistic empiricist who hopes to find the numbers actually occurring as properties of experienced objects. A pack of cards, for example. |
| 9795 | Numbers have generalised application to entities (such as bodies or sounds) [Mill] |
| Full Idea: 'Ten' must mean ten bodies, or ten sounds, or ten beatings of the pulse. But though numbers must be numbers of something, they may be numbers of anything. | |
| From: John Stuart Mill (System of Logic [1843], 2.6.2) | |
| A reaction: Mill always prefers things in close proximity, in space or time. 'I've had ten headaches in the last year'. 'There are ten reasons for doubting p'. His second point puts him very close to Aristotle in his view. |
| 9798 | Different parcels made from three pebbles produce different actual sensations [Mill] |
| Full Idea: Three pebbles make different sense impressions in one parcel or in two. That the same pebbles by an alteration of place and arrangement may be made to produce either sensation is not the identical proposition. | |
| From: John Stuart Mill (System of Logic [1843], 2.6.2) | |
| A reaction: [compressed] Not quite clear, but Mill seems to be adamant that we really must experience the separation, and not just think what 'may' happen, so Frege is right that Mill is lucky that everything is not 'nailed down'. |
| 9797 | '2 pebbles and 1 pebble' and '3 pebbles' name the same aggregation, but different facts [Mill] |
| Full Idea: The expressions '2 pebbles and 1 pebble' and '3 pebbles' stand for the same aggregation of objects, but do not stand for the same physical fact. They name the same objects in different states, 'denoting' the same things, with different 'connotations'. | |
| From: John Stuart Mill (System of Logic [1843], 2.6.2) | |
| A reaction: Nothing in this would convert me from the analytic view to the empirical view of simple arithmetic, if I were that way inclined. Personally I think of three pebbles as 4 minus 1, because I am haunted by the thought of a missing stone. |
| 9799 | 3=2+1 presupposes collections of objects ('Threes'), which may be divided thus [Mill] |
| Full Idea: 'Three is two and one' presupposes that collections of objects exist, which while they impress the senses thus, ¶¶¶, may be separated into two parts, thus, ¶¶ ¶. This being granted, we term all such parcels Threes. | |
| From: John Stuart Mill (System of Logic [1843], 2.6.2) | |
| A reaction: Mill is clearly in trouble here because he sticks to simple arithmetic. He must deal with parcels too big for humans to count, and parcels so big that they could not naturally exist, and that is before you even reach infinite parcels. |
| 9802 | Numbers denote physical properties of physical phenomena [Mill] |
| Full Idea: The fact asserted in the definition of a number is a physical fact. Each of the numbers two, three, four denotes physical phenomena, and connotes a physical property of those phenomena. Two denotes all pairs of things, and twelve all dozens. | |
| From: John Stuart Mill (System of Logic [1843], 3.24.5) | |
| A reaction: The least plausible part of Mill's thesis. Is the fact that a pair of things is fewer than five things also a property? You see two boots, or you see a pair of boots, depending partly on you. Is pure two a visible property? Courage and an onion? |
| 9803 | We can't easily distinguish 102 horses from 103, but we could arrange them to make it obvious [Mill] |
| Full Idea: 102 horses are not as easily distinguished from 103 as two are from three, yet the horses may be so placed that a difference will be perceptible. | |
| From: John Stuart Mill (System of Logic [1843], 3.24.5) | |
| A reaction: More trouble for Mill. We are now moving from the claim that we actually perceive numbers to the claim that we could if we arranged things right. But we would still only see which group of horses was bigger by one, not how many horses there were. |
| 9804 | Arithmetical results give a mode of formation of a given number [Mill] |
| Full Idea: Every statement of the result of an arithmetical operation is a statement of one of the modes of formation of a given number. | |
| From: John Stuart Mill (System of Logic [1843], 3.24.5) | |
| A reaction: Although Mill sticks cautiously to very simple arithmetic, inviting empirical accounts of much higher mathematics, I think the phrase 'modes of formation' of numbers is very helpful. It could take us either into structuralism, or into constructivism. |
| 9805 | 12 is the cube of 1728 means pebbles can be aggregated a certain way [Mill] |
| Full Idea: When we say 12 is the cube of 1728, we affirm that if we had sufficient pebbles, we put them into parcels or aggregates called twelves, and put those twelves into similar collections, and make twelve of these largests parcels, we have the aggregate 1728. | |
| From: John Stuart Mill (System of Logic [1843], 3.24.5) | |
| A reaction: There is always hidden modal thinking in Mill's proposals, despite his longing to stick to actual experience. Imagination actually plays a much bigger role in his theory than sense experience does. |
| 8741 | Numbers must be of something; they don't exist as abstractions [Mill] |
| Full Idea: All numbers must be numbers of something: there are no such things as numbers in the abstract. | |
| From: John Stuart Mill (System of Logic [1843], p.245?), quoted by Stewart Shapiro - Thinking About Mathematics 4.3 | |
| A reaction: This shows why the concept of 'abstraction' is such a deep problem. Numbers can't be properties of objects, because two boots can become one boot without changing the surviving boot. But why should abstractions have to 'exist'? |
| 12411 | Mill is too imprecise, and is restricted to simple arithmetic [Kitcher on Mill] |
| Full Idea: The problem with Mill is that many of his formulations are imprecise, and he only considers the most rudimentary parts of arithmetic. | |
| From: comment on John Stuart Mill (System of Logic [1843]) by Philip Kitcher - The Nature of Mathematical Knowledge Intro | |
| A reaction: This is from a fan of Mill, trying to restore his approach in the face of the authoritative and crushing criticisms offered by Frege. I too am a fan of Mill's approach. Patterns can be discerned in arrangements of pebbles. Infinities are a problem. |
| 5656 | Empirical theories of arithmetic ignore zero, limit our maths, and need probability to get started [Frege on Mill] |
| Full Idea: Mill does not give us a clue as to how to understand the number zero, he limits our mathematical knowledge to the limits of our experience, ..and induction can only give you probability, but that presupposes arithmetical laws. | |
| From: comment on John Stuart Mill (System of Logic [1843]) by Gottlob Frege - Grundlagen der Arithmetik (Foundations) | |
| A reaction: This summarises Frege's criticisms of Mill's empirical account of maths. I like 'maths is the science of patterns', in which case zero is just a late-introduced trick (it is hardly a Platonic Form!), and induction is the wrong account to give. |
| 9624 | Numbers are a very general property of objects [Mill, by Brown,JR] |
| Full Idea: Mill held that numbers are a kind of very general property that objects possess. | |
| From: report of John Stuart Mill (System of Logic [1843], Ch.4) by James Robert Brown - Philosophy of Mathematics | |
| A reaction: Intuitively this sounds hopeless, because if you place one apple next to another you introduce 'two', but which apple has changed its property? Both? It seems to be a Cambridge change. It isn't a change that would bother the apples. Kitcher pursues this. |
| 18317 | The 'real being' of things is a nothingness constructed from contradictions in the actual world [Nietzsche] |
| Full Idea: The characteristics which have been assigned to the 'real being' of things are the characteristics of non-being, of nothingness - the 'real world has been constructed out of the contradiction of the actual world. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.6) | |
| A reaction: I take this to be a critique of Hegel, in particular. Could we describe the metaphysics of Nietzsche as 'constructivist'? I certainly think he is underrated as a metaphysician, because the ideas are so fragmentary. |
| 18315 | We get the concept of 'being' from the concept of the 'ego' [Nietzsche] |
| Full Idea: Being is everywhere thought in, foisted on, as cause; it is only from the conception 'ego' that there follows, derivatively, the concept 'being'. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.5) | |
| A reaction: 'Being' is such a remote abstraction that I doubt whether we can say anything at all meaningful about where it 'comes from'. |
| 18316 | The grounds for an assertion that the world is only apparent actually establish its reality [Nietzsche] |
| Full Idea: The grounds upon which 'this' world has been designated as apparent establish rather its reality - another kind of reality is absolutely undemonstrable. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.6) |
| 18314 | In language we treat 'ego' as a substance, and it is thus that we create the concept 'thing' [Nietzsche] |
| Full Idea: It is the metaphysics of language (that is, of reason) ....which believes in the 'ego', in the ego as being, in the ego as substance, and which projects its belief in the ego-substance on to all things - only thus does it create the concept 'thing'. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.5) |
| 9806 | Whatever is made up of parts is made up of parts of those parts [Mill] |
| Full Idea: Whatever is made up of parts is made up of parts of those parts. | |
| From: John Stuart Mill (System of Logic [1843], 3.24.5) | |
| A reaction: Mill considers this principle to be fundamental to the possibilities of arithmetic. Presumably he thought of it as an inductive inference from our dealings with physical objects. |
| 11156 | The essence is that without which a thing can neither be, nor be conceived to be [Mill] |
| Full Idea: The essence of a thing was said to be that without which the thing could neither be, nor be conceived to be. | |
| From: John Stuart Mill (System of Logic [1843], 1.6.2) | |
| A reaction: Fine cites this as the 'modal' account of essence, as opposed to the 'definitional' account. |
| 12190 | Necessity is what will be, despite any alternative suppositions whatever [Mill] |
| Full Idea: That which is necessary, that which must be, means that which will be, whatever suppositions we may make in regard to all other things. | |
| From: John Stuart Mill (System of Logic [1843], 3.06.6) | |
| A reaction: [Mill discusses causal necessity] This is quoted by McFetridge. This slightly firms up the definition as 'what has to be true', though it makes it dependent on our 'suppositions'. Presumably nothing beyond our powers of supposition could matter either. |
| 22623 | Necessity can only mean what must be, without conditions of any kind [Mill] |
| Full Idea: If there be any meaning which confessedly belongs to the term necessity, it is unconditionalness. That which is necessary, that which must be, means that which will be whatever supposition we make with regard to other things. | |
| From: John Stuart Mill (System of Logic [1843], p.339 [1974 ed]), quoted by R.D. Ingthorsson - A Powerful Particulars View of Causation 5.3 | |
| A reaction: 'It is necessary to leave now, if you want to catch the train' is a genuine type of necessity. Mill's type is probably Absolute necessity, to which nothing could make any difference. Or Metaphysical necessity, determined by all things. |
| 18309 | The evidence of the senses is falsified by reason [Nietzsche] |
| Full Idea: 'Reason' is the cause of our falsification of the evidence of the senses. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.1) | |
| A reaction: One for McDowell. |
| 16859 | Most perception is one-tenth observation and nine-tenths inference [Mill] |
| Full Idea: In almost every act of our perceiving faculties, observation and inference are intimately blended. What we are said to observe is usually a compound result, of which one-tenth may be observation, and the remaining nine-tenths inference. | |
| From: John Stuart Mill (System of Logic [1843], 4.1.2), quoted by Peter Lipton - Inference to the Best Explanation (2nd) 11 'The scientific' | |
| A reaction: We seem to think that his kind of observation is a great realisation of twentieth century thought, but thoughtful empiricists spotted it much earlier. |
| 9082 | Clear concepts result from good observation, extensive experience, and accurate memory [Mill] |
| Full Idea: The principle requisites of clear conceptions, are habits of attentive observation, an extensive experience, and a memory which receives and retains an exact image of what is observed. | |
| From: John Stuart Mill (System of Logic [1843], 4.2.5) | |
| A reaction: Empiricists are always crying out for people to 'attend to the evidence', and this is the deeper reason why. Not only will one know the world better in a direct way, but one will actually think more clearly. Darwin is the perfect model for this. |
| 16860 | Inductive generalisation is more reliable than one of its instances; they can't all be wrong [Mill] |
| Full Idea: A general proposition collected from particulars is often more certainly true than any one of the particular propositions from which, by an act of induction, it was inferred. It might be erroneous in any instance, but cannot be erroneous in all of them. | |
| From: John Stuart Mill (System of Logic [1843], 4.1.2), quoted by Peter Lipton - Inference to the Best Explanation (2nd) 11 'The scientific' | |
| A reaction: One anomaly can be ignored, but several can't, especially if the anomalies agree. |
| 16845 | The whole theory of induction rests on causes [Mill] |
| Full Idea: The notion of cause is the root of the whole theory of induction. | |
| From: John Stuart Mill (System of Logic [1843], 3.05.2), quoted by Peter Lipton - Inference to the Best Explanation (2nd) 08 'From cause' | |
| A reaction: This sounds much better to me than the Humean view that it rests on the psychology of regularity and habit. However, maybe Hume describes induction, and Mill is adding abduction (inference to the best explanation). |
| 16843 | Mill's methods (Difference,Agreement,Residues,Concomitance,Hypothesis) don't nail induction [Mill, by Lipton] |
| Full Idea: The Method of Difference, and even the full four 'experimental methods' (Difference, Agreement, Residues and Concomitant Variations) are agreed on all sides to be incomplete accounts of inductive inference. Mill himself added the Method of Hypothesis. | |
| From: report of John Stuart Mill (System of Logic [1843], 3.14.4-5) by Peter Lipton - Inference to the Best Explanation (2nd) 08 'Improved' | |
| A reaction: If induction is just 'learning from experience' (my preferred definition) then there is unlikely to be a precise account of its methods. Mill seems to have done a lovely job. |
| 17086 | Surprisingly, empiricists before Mill ignore explanation, which seems to transcend experience [Mill, by Ruben] |
| Full Idea: It is surprising that no empiricist philosopher before Mill turned in an explicit way to the scrutiny of the concept of explanation, which had …every appearance of being experience-transcendent. | |
| From: report of John Stuart Mill (System of Logic [1843]) by David-Hillel Ruben - Explaining Explanation Ch 4 | |
| A reaction: Yes indeed! This is why explanation is absolutely basic, to philosophy and to human understanding. The whole of philosophy is a quest for explanations, so to be strictly empirical about it strikes me as crazy. |
| 17091 | Explanation is fitting of facts into ever more general patterns of regularity [Mill, by Ruben] |
| Full Idea: For Mill, explanation was always the fitting of facts into ever more general patterns of regularity. | |
| From: report of John Stuart Mill (System of Logic [1843]) by David-Hillel Ruben - Explaining Explanation Ch 6 | |
| A reaction: This seems to nicely capture the standard empirical approach to explanation. If you say that this fitting in doesn't explain much, the answer (I think) is that this is the best we can do. |
| 16805 | Causal inference is by spotting either Agreements or Differences [Mill, by Lipton] |
| Full Idea: The best known account of causal inference is Mill's Method of Agreement (only one antecedent is shared by the effects), and the Method of Difference (there is only one difference prior to the effect occurring or not occurring). | |
| From: report of John Stuart Mill (System of Logic [1843], 3.07) by Peter Lipton - Inference to the Best Explanation (2nd) 01 'Descr' | |
| A reaction: [my summary of Lipton's summary of Mill] |
| 16835 | The Methods of Difference and of Agreement are forms of inference to the best explanation [Mill, by Lipton] |
| Full Idea: Like Mill's Method of Difference, applications of the Method of Agreement are naturally construed as inferences to the best explanation. | |
| From: report of John Stuart Mill (System of Logic [1843], 3.07/8) by Peter Lipton - Inference to the Best Explanation (2nd) 06 'The Method' | |
| A reaction: This sort of thoroughly sensible approach to understanding modes of investigation has been absurdly sidelined by the desire to 'deduce' observations from 'laws'. Scientific investigation is no different from enquiry in daily life. Where are my glasses? |
| 18323 | Any explanation will be accepted as true if it gives pleasure and a feeling of power [Nietzsche] |
| Full Idea: To trace something unknown back to something known is alleviating, soothing, gratifying and gives moreover a feeling of power. ...First principle: any explanation is better than none. ...Proof by pleasure ('by potency') as criterion of truth. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 5.5) | |
| A reaction: By 'proof by pleasure' he means that we find an explanation so satisfying that we cling to it. I assume it is a criterion of rationality (an epistemic virtue) to reject the principle 'any explanation is better than none'. Negative capability. |
| 9079 | We can focus our minds on what is common to a whole class, neglecting other aspects [Mill] |
| Full Idea: The voluntary power which the mind has, of attending to one part of what is present at any moment, and neglecting another part, enables us to be unaffected by anything in the idea which is not really common to the whole class. | |
| From: John Stuart Mill (System of Logic [1843], 4.2.1) | |
| A reaction: There is a question for empiricists of whether abstraction is a 'voluntary' power or a mechanical one. Associationism presents it as more mechanical. I would say, with Mill, that it is a least partly voluntary, and even rational. |
| 18310 | The 'highest' concepts are the most general and empty concepts [Nietzsche] |
| Full Idea: The 'highest concepts' ...are the most general, the emptiest concepts, the last fumes of evaporating reality. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.4) | |
| A reaction: This could be seen as an attack on the aspirations of all of philosophy, which seeks general truths out of the chaos of experience. Should we shut up, then, and just be and do? |
| 9081 | We don't recognise comparisons by something in our minds; the concepts result from the comparisons [Mill] |
| Full Idea: It is not a law of our intellect that in comparing things and noting their agreements we recognise as realized in the outward world something we already had in our minds. The conception found its way to us as the result of such a comparison. | |
| From: John Stuart Mill (System of Logic [1843], 4.2.2) | |
| A reaction: He recognises, of course, that this gradually becomes a two-way process. In the physicalist view of things, it is not really of great importance which concepts are hard-wired, and which constructed culturally or through perception. |
| 3238 | 'Dead person' isn't a contradiction, so 'person' is somewhat vague [Williams,B] |
| Full Idea: If we say (in opposition to a physical view of identity) that when Jones dies 'Jones ceases to exist' but 'Jones' body does not cease to exist', this shouldn't be pressed too hard, because it would make 'dead person' a contradiction. | |
| From: Bernard Williams (Are Persons Bodies? [1970], p.74) | |
| A reaction: A good point, which nicely challenges the distinction between a 'human' and a 'person', but the problem case is much more the one where Jones gets advanced Alzheimer's, rather than dies. A dead body ceases as a mechanism, as well as as a personality. |
| 3239 | You can only really love a person as a token, not as a type [Williams,B] |
| Full Idea: If you love a person as a type instead of as a token (i.e. a "person", instead of a physical body) you might prefer a run-down copy of them to no person at all, but at this point our idea of loving a person begins to crack. | |
| From: Bernard Williams (Are Persons Bodies? [1970], p.81) | |
| A reaction: Very persuasive. If you love a person you can cope with them getting old. If you own an original watercolour, you can accept that it fades, but you would replace a reproduction of it if that faded. But what, then, is it that you love? |
| 20368 | There are no 'individual' persons; we are each the sum of humanity up to this moment [Nietzsche] |
| Full Idea: The 'individual' ...is an error: he does not constitute a separate entity, an atom, a 'link in the chain', something merely inherited from the past - he constitutes the entire single line 'man' up to and including himself. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.33) | |
| A reaction: I'm not sure I understand this, but you can sort of imagine yourself as a culmination of something, rather than as an isolated entity. I'm not sure how that is supposed to affect my behaviour. |
| 2899 | The fanatical rationality of Greek philosophy shows that they were in a state of emergency [Nietzsche] |
| Full Idea: The fanaticism with which the whole of Greek thought throws itself at rationality betrays itself as a state of emergency: one was in peril, one had only one choice: either to perish or- be absurdly rational. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.10) |
| 9080 | General conceptions are a necessary preliminary to Induction [Mill] |
| Full Idea: Forming general conceptions is a necessary preliminary to Induction. | |
| From: John Stuart Mill (System of Logic [1843], 4.2.1) | |
| A reaction: A key link in the framework of empirical philosophies, which gets us from experience to science. Induction is the very process of generalisation. We can't bring a concept like 'evolution' to preliminary observations, so it must be formulated inductively. |
| 9078 | The study of the nature of Abstract Ideas does not belong to logic, but to a different science [Mill] |
| Full Idea: The metaphysical inquiry into the nature and composition of what have been called Abstract Ideas, or in other words, of the notions which answer in the mind to classes and to general names, belongs not to Logic, but to a different science. | |
| From: John Stuart Mill (System of Logic [1843], 4.2.1) | |
| A reaction: He doesn't name the science, but the point here seems to be precisely what Frege so vigorously disagreed with. I would say that the state of being 'abstract' has logical aspects, and can be partly described by logic, but that Mill is basically right. |
| 18313 | The big error is to think the will is a faculty producing effects; in fact, it is just a word [Nietzsche] |
| Full Idea: At the beginning stands the great fateful error that the will is something which produces an effect - that will is a faculty.... Today we know it is merely a word. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.5) | |
| A reaction: This is despite Nietzsche's insistence that 'will to power' is the central fact of active existence. The misreading of Nietzsche is to think that this refers to the conscious exercising of a mental faculty. |
| 20133 | The 'motive' is superficial, and may even hide the antecedents of a deed [Nietzsche] |
| Full Idea: The so-called 'motive' is another error. Merely a surface phenomenon of consciousness - something alongside the deed which is more likely to cover up the antecedents of the deed than to represent them. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 6.3) | |
| A reaction: [Leiter gives 'VI.3', but I can't find it] As far as you can get from intellectualism about action, and is more in accord with the picture found in modern neuro-science. No one knows why they are 'interested' in something, and that's the start of it. |
| 18326 | The beautiful never stands alone; it derives from man's pleasure in man [Nietzsche] |
| Full Idea: Anyone who tried to divorce the beautiful from man's pleasure in man would at once feel the ground give way beneath him. The 'beautiful in itself' is not even a concept, merely a phrase. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.19) | |
| A reaction: I love the insult 'not even a concept'! It's like Pauli's 'not even wrong'! |
| 20101 | Without music life would be a mistake [Nietzsche] |
| Full Idea: Without music life would be a mistake. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], Maxim 33) | |
| A reaction: Cf Schopenhauer in Idea 21469. If you, dear reader, don't love music, then I sincerely hope that there is something in your life which can match it. |
| 2902 | Healthy morality is dominated by an instinct for life [Nietzsche] |
| Full Idea: All naturalism in morality, that is all healthy morality, is dominated by an instinct for life. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.4) | |
| A reaction: Sounds right. There is no reasoning against a moral nihilist, because they seem to have no instinct in favour of life. It is the given of morality. |
| 18311 | Philosophers hate values having an origin, and want values to be self-sufficient [Nietzsche] |
| Full Idea: For philosophers, the higher must not be allowed to grow out of the lower, must not be allowed to have grown at all ...Moral: everything of the first rank must be causa sui. Origin in something else counts as an objection, as casting a doubt on value. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.4) | |
| A reaction: This is so deep and central that I wrote a paper on it, advocating that the theory of values should focus of value-makers. |
| 18324 | There are no moral facts, and moralists believe in realities which do not exist [Nietzsche] |
| Full Idea: An insight formulated by me: that there are no moral facts whatever. Moral judgement has this in common with religious judgement that it believes in realities which do not exist. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 6.1) | |
| A reaction: Not only a slogan for non-cognitivism, but also a clear statement of the error theory about morality, a century before John Mackie. |
| 2904 | The doctrine of free will has been invented essentially in order to blame and punish people [Nietzsche] |
| Full Idea: The doctrine of will has been invented essentially for the purpose of punishment, that is of finding guilty. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 5.7) | |
| A reaction: Michael Frede says free will was invented to feel wholly in charge of our own actions. I doubt whether punishment was the first motive. The will just gives a simple explanation of actions. |
| 2895 | The value of life cannot be estimated [Nietzsche] |
| Full Idea: The value of life cannot be estimated. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.02) | |
| A reaction: Military leaders apparently judge that the death of one of their own soldiers is worth between 12 and 20 enemy deaths (so history suggests). How about ransom money? |
| 18322 | When we establish values, that is life itself establishing them, through us [Nietzsche] |
| Full Idea: When we speak of values we do so under the inspiration and from the perspective of life: life itself evaluates through us when we establish values | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.5) | |
| A reaction: I love Nietzsche's ideas about the source of values, and his remarks about the value of life. Other thinkers sound so simplistic in comparison. |
| 2893 | In every age the wisest people have judged life to be worthless [Nietzsche] |
| Full Idea: In every age the wisest have passed the identical judgement on life: it is worthless. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.01) | |
| A reaction: I guess he was having a bad day. Since the whole universe is clearly 'worthless', this judgement must in some sense be correct. But I love my books. |
| 18308 | A philosopher fails in wisdom if he thinks the value of life is a problem [Nietzsche] |
| Full Idea: For a philosopher to see a problem in the value of life thus even constitutes an objection to him, a question-mark as to his wisdom, a piece of unwisdom. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.02) | |
| A reaction: I take his point to be neither that life is unquestionably valuable nor that it is valueless, but that the very question is ridiculous. If we live, we value living. Sounds right. |
| 2894 | Value judgements about life can never be true [Nietzsche] |
| Full Idea: Judgements, value judgements concerning life, for or against it, can in the last resort never be true. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 1.02) | |
| A reaction: I suppose this is in the same spirit as judging whether celery tastes nice. Are you for or against the Moon? |
| 18321 | To evaluate life one must know it, but also be situated outside of it [Nietzsche] |
| Full Idea: One would have to be situated outside life ....[and yet know it thoroughly] ....to be permitted to touch on the problem of the value of life at all. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.5) | |
| A reaction: Can practising artists question the value of their art? The whole point of objectivity is that we can mentally step 'outside' of something, without actually withdrawing from it. |
| 18319 | Love is the spiritualisation of sensuality [Nietzsche] |
| Full Idea: The spiritualization of sensuality is called 'love': it is a great triumph over Christianity. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.3) | |
| A reaction: I'm not quite clear what 'spiritualization' means, particularly when it comes from Nietzsche. |
| 2903 | A good human will be virtuous because they are happy [Nietzsche] |
| Full Idea: A well-constituted human being, a 'happy one', must perform certain actions and shrink from other actions. In a formula: his virtue is the consequence of his happiness. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 5.2) | |
| A reaction: A nice reversal of basic Aristotle, though Aristotle does say that the truly virtuous person is happy in their actions. Treat unhappy people with caution! |
| 2891 | Only the English actually strive after happiness [Nietzsche] |
| Full Idea: Man does not strive after happiness; only the Englishman does that. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], Maxim 12) | |
| A reaction: The Danes keeping being voted the happiest nation, so presumably that results from some sort of effort on their part. The easiest is happiness is to achieve security, then do nothing. |
| 18327 | A wholly altruistic morality, with no egoism, is a thoroughly bad thing [Nietzsche] |
| Full Idea: An 'altruistic' morality, a morality under which egoism languishes - is under all circumstances a bad sign. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.35) |
| 15606 | Military idea: what does not kill me makes me stronger [Nietzsche] |
| Full Idea: From the military school of life. - What does not kill me makes me stronger. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], Maxim 08) | |
| A reaction: The published version! Perhaps the most famous remark in all of Nietzsche, and no one realises it is ironic! It is a sarcastic remark about the battering ram mentality of the Prussian militarist! He had served in the army. |
| 18328 | Invalids are parasites [Nietzsche] |
| Full Idea: The invalid is a parasite on society. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.36) | |
| A reaction: I'll skip the rest, but you get the idea. The point (with which I sympathise) is that life is primarily about what healthy people do. Something has gone wrong if all we do is worry about the sick and the suffering. |
| 18331 | Democracy is organisational power in decline [Nietzsche] |
| Full Idea: Democracy has always been the declining form of the power to organise. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.39) | |
| A reaction: Even when Nietzsche is wrong (and who knows, here?) he always challenges you to think! |
| 18332 | The creation of institutions needs a determination which is necessarily anti-liberal [Nietzsche] |
| Full Idea: For institutions to exist there must exist the kind of will, instinct, imperative which is anti-liberal to the point of malice: the will to tradition, to authority, to centuries-long responsibility, to solidarity between succeeding generations. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.39) | |
| A reaction: This sounds like a lovely challenge to Popper, who seems to have been a liberal who pinned his faith on institutions. |
| 2911 | True justice is equality for equals and inequality for unequals [Nietzsche] |
| Full Idea: 'Equality for equals, inequality for unequals' - that would be the true voice of justice. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.48) |
| 18320 | To renounce war is to renounce the grand life [Nietzsche] |
| Full Idea: One has renounced grand life when one renounces war. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.3) | |
| A reaction: Nietzsche was a medical orderly in the 1870 Franco-Prussian war, so he had seen it at first hand. I think the machine gun and the heavy bomber would have changed his attitude to warfare. He sounds a bit silly now. Nostalgia for the Iliad. |
| 2908 | There is a need for educators who are themselves educated [Nietzsche] |
| Full Idea: There is a need for educators who are themselves educated. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 7.5) |
| 18329 | Sometimes it is an error to have been born - but we can rectify it [Nietzsche] |
| Full Idea: We have no power to prevent ourselves being born: but we can rectify this error - for sometimes it is an error. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.36) |
| 2905 | 'Purpose' is just a human fiction [Nietzsche] |
| Full Idea: We invented the concept 'purpose': in reality purpose is lacking. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 5.8) |
| 8345 | A cause is the total of all the conditions which inevitably produce the result [Mill] |
| Full Idea: A cause is the sum total of the conditions positive and negative taken together ...which being realized, the consequent invariably follows. | |
| From: John Stuart Mill (System of Logic [1843]), quoted by Donald Davidson - Causal Relations §1 | |
| A reaction: This has obvious problems. The absence of Napoleon was a cause of the English Civil War. The Big Bang was a cause of, well, every event. As Davidson notes, some narrowing down is needed. |
| 10391 | Causes and conditions are not distinct, because we select capriciously from among them [Mill] |
| Full Idea: Nothing can better show the absence of any scientific ground for the distinction between the cause of a phenomena and its conditions, than the capricious manner in which we select from among the conditions that which we choose to denominate the cause. | |
| From: John Stuart Mill (System of Logic [1843]), quoted by Jonathan Schaffer - The Metaphysics of Causation 2.2 | |
| A reaction: [ref Mill p.196, 1846 edn] Schaffer gives this as the main argument for the 'no-basis' view of the selection of what causes an event. The usual thought is that it is entirely our immediate interests which make us select THE cause. Not convinced. |
| 14547 | The strict cause is the total positive and negative conditions which ensure the consequent [Mill] |
| Full Idea: The cause, philosophically speaking, is the sum total of the conditions, positive and negative taken together; the whole of the contigencies of every description, which being realized, the consequent invariably follows. | |
| From: John Stuart Mill (System of Logic [1843], 3.05.3) | |
| A reaction: This somewhat notorious remark is not going to be much help in a law court or a laboratory. It is that view which says that the Big Bang must be included in every causal list ever compiled. Well, yes... |
| 8377 | Causation is just invariability of succession between every natural fact and a preceding fact [Mill] |
| Full Idea: The Law of Causation, the recognition of which is the main pillar of inductive science, is but the familiar truth, that invariability of succession is found by observation between every fact in nature and some other fact which has preceded it. | |
| From: John Stuart Mill (System of Logic [1843], 3.5.2), quoted by Bertrand Russell - On the Notion of Cause p.178 | |
| A reaction: Note that Mill rests causation on 'facts'. In the empiricist Mill endorsing the views of Hume. Russell attacks the bogus claim that science rests on causation. Personally I think Mill's view is incorrect. |
| 14545 | A cause is an antecedent which invariably and unconditionally leads to a phenomenon [Mill] |
| Full Idea: We may define the cause of a phenomenon to be the antecedent, or the concurrence of the antecedents, on which it is invariably and unconditionally consequent. | |
| From: John Stuart Mill (System of Logic [1843], 3.05.6) | |
| A reaction: This ignores the possibility of the world ending just before the effect occurs, the 'ceteris paribus' clause. If it only counts as a cause if the effect has actually occurred, we begin to suspect tautology. |
| 4773 | Mill's regularity theory of causation is based on an effect preceded by a conjunction of causes [Mill, by Psillos] |
| Full Idea: Millian causation is a version of the Regularity Theory, but with the addition that when claiming that an effect invariably follows from the cause, the cause is not a single factor, but a whole conjunction of necessary and sufficient conditions. | |
| From: report of John Stuart Mill (System of Logic [1843], p.217) by Stathis Psillos - Causation and Explanation §2.2 | |
| A reaction: Psillos endorses this as an improvement on Hume. But while we may replicate one event preceding another to get regularity, groups of events are hardly ever identical, so no precise pattern will ever be seen. |
| 4775 | In Mill's 'Method of Agreement' cause is the common factor in a range of different cases [Mill, by Psillos] |
| Full Idea: In Mill's 'Method of Agreement' the cause is the common factor in a number of otherwise different cases in which the effect occurs. | |
| From: report of John Stuart Mill (System of Logic [1843], p.255) by Stathis Psillos - Causation and Explanation §2.3 | |
| A reaction: This looks more likely to be good evidence for the cause of an event, rather than a definition of what a cause actually is. Suppose a footballer only scores if and only if I go to watch him? |
| 4776 | In Mill's 'Method of Difference' the cause is what stops the effect when it is removed [Mill, by Psillos] |
| Full Idea: In Mill's 'Method of Difference' the cause is the factor which is different in two cases which are similar, except that in one the effect occurs, and in the other it doesn't. | |
| From: report of John Stuart Mill (System of Logic [1843], p.256) by Stathis Psillos - Causation and Explanation §2.3 | |
| A reaction: Like the Method of Agreement, this is a good test, but is unlikely to be a conclusive hallmark of causation. A footballer may never score unless I go to watch him. I become his lucky mascot… |
| 9417 | What are the fewest propositions from which all natural uniformities could be inferred? [Mill] |
| Full Idea: What are the fewest general propositions from which all the uniformities which exist in the universe might be deductively inferred? | |
| From: John Stuart Mill (System of Logic [1843], 3.4.1) | |
| A reaction: This is the germ of the Mill-Ramsey-Lewis view. |
| 18312 | The supreme general but empty concepts must be compatible, and hence we get 'God' [Nietzsche] |
| Full Idea: The supreme concepts of philosophers cannot be incommensurate with one another, be incompatible with one another... Thus they acquired their stupendous concept 'God'.... The last, thinnest, emptiest is placed as the first, as cause in itself. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.4) |
| 2906 | By denying God we deny human accountability, and thus we redeem the world [Nietzsche] |
| Full Idea: We deny God; in denying God we deny accountability; only by doing that do we redeem the world. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 5.8) |
| 2901 | How could the Church intelligently fight against passion if it preferred poorness of spirit to intelligence? [Nietzsche] |
| Full Idea: The primitive church fought against the 'intelligent' in favour of the 'poor in spirit': how could one expect from it an intelligent war against passion? | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 4.1) |
| 18325 | Christians believe that only God can know what is good for man [Nietzsche] |
| Full Idea: Christianity presupposes that man does not know, cannot know what is good for him and what evil: he believes in God, who alone knows. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 8.05) |
| 18318 | People who disparage actual life avenge themselves by imagining a better one [Nietzsche] |
| Full Idea: If there is a strong instinct for slandering, disparaging and accusing life within us, then we revenge ourselves on life by means of the phantasmagoria of 'another', a 'better' life. | |
| From: Friedrich Nietzsche (Twilight of the Idols [1889], 2.6) |
