| 23948 | Wisdom needs both thought and passion, with each reflecting on the other [Solomon] |
| Full Idea: Wisdom is a matter of living both thoughtfully and passionately, bringing understanding to bear on every passion and forcing every passion into the light of reflection. | |
| From: Robert C. Solomon (The Passions [1976], 3.4) | |
| A reaction: His main point is that passion is a key part of wisdom, and the idea that wisdom is cold and detached is quite false. Good point. At the very least, wise people must relate sympathetically to others. |
| 18730 | The history of philosophy only matters if the subject is a choice between rival theories [Wittgenstein] |
| Full Idea: If philosophy were a matter of choice between rival theories, then it would be sound to teach it historically. But if it is not, then it is a fault to teach it historically, because it is quite unnecessary; we can tackle the subject direct. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], C V A) | |
| A reaction: Wittgenstein was a bit notorious for not knowing the history of the subject terribly well, and this explains why. Presumably our tackling the subject direct will not have the dreadful consequence of producing yet another theory. |
| 18704 | Philosophy tries to be rid of certain intellectual puzzles, irrelevant to daily life [Wittgenstein] |
| Full Idea: Philosophy is the attempt to be rid of a particular kind of puzzlement. This 'philosophical' puzzlement is one of the intellect and not of instinct. Philosophical puzzles are irrelevant to our every-day life. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], A I.1) | |
| A reaction: All enquiry begins with puzzles, and they are cured by explanations, which result in understanding. In that sense he is right. I entirely disagree that the puzzles are irrelevant to daily life. |
| 18710 | Philosophers express puzzlement, but don't clearly state the puzzle [Wittgenstein] |
| Full Idea: Philosophers as 'Why?' and 'What?' without knowing clearly what their questions are. They are expressing a feeling of mental uneasiness. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B I.1) | |
| A reaction: He suggests it is childish to express puzzlement, instead of asking for precise information. How odd. All enquiries start with vague puzzlement, which gradually comes into focus, or else is abandoned. |
| 23942 | Philosophy is creating an intellectual conceptual structure for life [Solomon] |
| Full Idea: Philosophy is conceptual sculpture, the shaping and developing of the intellectual structures within which we live our lives. | |
| From: Robert C. Solomon (The Passions [1976], Intro.1) | |
| A reaction: Nice. I tend to see philosophy as conceptual analysis (though creating new concepts doesn't quite fit that), but the vision of creating a huge conceptual sculpture sounds good. I would call it a system. (See my book, 'Natural Ideas'!). |
| 18732 | We don't need a theory of truth, because we use the word perfectly well [Wittgenstein] |
| Full Idea: It is nonsense to try to find a theory of truth, because we can see that in everyday life we use the word quite clearly and definitely in various different senses. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], C V B) | |
| A reaction: This was a year before Tarski published his famous theory of truth for formal languages. Prior to that, most philosophers were giving up on truth. Would he say the same about 'gravity' or 'inflation'? |
| 22270 | Frege changed philosophy by extending logic's ability to check the grounds of thinking [Potter on Frege] |
| Full Idea: Frege's 1879 logic transformed philosophy because it greatly expanded logic's reach - what thought can achieve unaided - and hence compelled a re-examination of everything previously said about the grounds of thought when logic gives out. | |
| From: comment on Gottlob Frege (Begriffsschrift [1879]) by Michael Potter - The Rise of Analytic Philosophy 1879-1930 Intro | |
| A reaction: I loved the gloss on logic as 'what thought can achieve unaided'. I largely see logic in terms of what is mechanically computable. |
| 18714 | We already know what we want to know, and analysis gives us no new facts [Wittgenstein] |
| Full Idea: In philosophy we know already all that we want to know; philosophical analysis does not give us any new facts. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B V.1) |
| 23945 | Reason is actually passions, guided by perspicacious reflection [Solomon] |
| Full Idea: What is called 'reason' is the passions enlightened, 'illuminated' by reflection and supported by a perspicacious deliberation that the emotions in their urgency normally excluded. | |
| From: Robert C. Solomon (The Passions [1976], Intro.4) | |
| A reaction: To suggest that reason more or less is emotions strikes me as missing the point of 'perspicacious', which takes in facts outside our emotional world. We excitedly climb a cliff, then stop when we see the rocks are crumbling. |
| 8939 | We should not describe human laws of thought, but how to correctly track truth [Frege, by Fisher] |
| Full Idea: Frege disagree that logic should merely describe the laws of thought - how people actually did reason. Logic is essentially normative, not descriptive. We want the one logic which successfully tracks the truth. | |
| From: report of Gottlob Frege (Begriffsschrift [1879]) by Jennifer Fisher - On the Philosophy of Logic 1.III | |
| A reaction: This explains Frege's sustained attack on psychologism, and it also explains we he ended up as a platonist about logic - because he wanted its laws to be valid independently of human thinking. A step too far, perhaps. Brains are truth machines. |
| 18706 | Words of the same kind can be substituted in a proposition without producing nonsense [Wittgenstein] |
| Full Idea: 'Blue' and 'brown' are of the same kind, for the substitution of one for the other, though it may falsify the proposition, does not make nonsense of it. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], A I.4) | |
| A reaction: He chooses an easy example, because they are determinates of the determinable 'coloured'. What if I say 'the sky is blue', and then substitute 'frightening' for 'blue'? |
| 18735 | Talking nonsense is not following the rules [Wittgenstein] |
| Full Idea: Talking nonsense is not following the rules. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], C X) | |
| A reaction: He doesn't seem to distinguish between syntax and semantics, and makes it sound as if all nonsense is syntactic, which it isn't. |
| 18719 | Grammar says that saying 'sound is red' is not false, but nonsense [Wittgenstein] |
| Full Idea: If grammar says that you cannot say that a sound is red, it means not that it is false to say so but that it is nonsense - i.e. not a language at all. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B IX.6) | |
| A reaction: I am baffled as to why he thinks 'grammar' is what prohibits such a statement. Surely the world, the nature of sound and colour, is what makes the application of the predicate wrong. Sounds aren't coloured, so they can't be red. False, not nonsense. |
| 18731 | There is no theory of truth, because it isn't a concept [Wittgenstein] |
| Full Idea: It is wrong to say that there is any one theory of truth, for truth is not a concept. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], C V B) | |
| A reaction: This makes you wonder how he understood the word 'concept'. In most modern discussions truth seems to be a concept, and in Frege it can be an unsaturated predicate which is satisfied by sentences or thoughts. |
| 18707 | All thought has the logical form of reality [Wittgenstein] |
| Full Idea: Thought must have the logical form of reality if it is to be thought at all. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], A V.1) | |
| A reaction: This links nicely the idea that true thoughts somehow share the structure of what they refer to, with the idea of logical form in logic. But maybe logical form is a fiction we offer in order to obtain a spurious map of reality. |
| 4971 | I don't use 'subject' and 'predicate' in my way of representing a judgement [Frege] |
| Full Idea: A distinction of subject and predicate finds no place in my way of representing a judgement. | |
| From: Gottlob Frege (Begriffsschrift [1879], §03) | |
| A reaction: Perhaps this sentence could be taken as the beginning of modern analytical philosophy. The old view doesn't seem to me entirely redundant - merely replaced by a much more detailed analysis of what makes a 'subject' and what makes a 'predicate'. |
| 17745 | For Frege, 'All A's are B's' means that the concept A implies the concept B [Frege, by Walicki] |
| Full Idea: 'All A's are B's' meant for Frege that the concept A implies the concept B, or that to be A implies also to be B. Moreover this applies to arbitrary x which happens to be A. | |
| From: report of Gottlob Frege (Begriffsschrift [1879]) by Michal Walicki - Introduction to Mathematical Logic History D.2 | |
| A reaction: This seems to hit the renate/cordate problem. If all creatures with hearts also have kidneys, does that mean that being enhearted logically implies being kidneyfied? If all chimps are hairy, is that a logical requirement? Is inclusion implication? |
| 7728 | Frege has a judgement stroke (vertical, asserting or judging) and a content stroke (horizontal, expressing) [Frege, by Weiner] |
| Full Idea: Frege distinguished between asserting a proposition and expressing it, and he introduced the judgement stroke (a small vertical line, assertion) and the content stroke (a long horizontal line, expression) to represent them. | |
| From: report of Gottlob Frege (Begriffsschrift [1879]) by Joan Weiner - Frege Ch.3 | |
| A reaction: There are also strokes for conditional and denial. |
| 18724 | In logic nothing is hidden [Wittgenstein] |
| Full Idea: In logic nothing is hidden. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B XII.3) | |
| A reaction: If so, then the essence of logic must be there for all to see. The rules of natural deduction are a good shot at showing this. |
| 16881 | The laws of logic are boundless, so we want the few whose power contains the others [Frege] |
| Full Idea: Since in view of the boundless multitude of laws that can be enunciated we cannot list them all, we cannot achieve completeness except by searching out those that, by their power, contain all of them. | |
| From: Gottlob Frege (Begriffsschrift [1879], §13) | |
| A reaction: He refers to these laws in the previous sentence as the 'core'. His talk of 'power' is music to my ears, since it implies a direction of explanation. Burge says the power is that of defining other concepts. |
| 7622 | In 1879 Frege developed second order logic [Frege, by Putnam] |
| Full Idea: By 1879 Frege had discovered an algorithm, a mechanical proof procedure, that embraces what is today standard 'second order logic'. | |
| From: report of Gottlob Frege (Begriffsschrift [1879]) by Hilary Putnam - Reason, Truth and History Ch.5 | |
| A reaction: Note that Frege did more than introduce quantifiers, and the logic of predicates. |
| 18709 | Laws of logic are like laws of chess - if you change them, it's just a different game [Wittgenstein] |
| Full Idea: I might as well question the laws of logic as the laws of chess. If I change the rules it is a different game and there is an end of it. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], A XI.3) | |
| A reaction: No, that isn't the end of it, because there are meta-criteria for preferring one game to another. Why don't we just give up classical logic? It would be such fun to have a wild wacky logic. We can start with 'tonk'. |
| 18736 | Contradiction is between two rules, not between rule and reality [Wittgenstein] |
| Full Idea: Contradiction is between one rule and another, not between rule and reality. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], C XIII) | |
| A reaction: If I say 'he is sitting' and 'he is standing', it seems to be reality which produces the contradiction. What 'rule' could possibly do it? The rule which says sitting and standing are incompatible? But what makes that so? |
| 7729 | Frege replaced Aristotle's subject/predicate form with function/argument form [Frege, by Weiner] |
| Full Idea: Frege's regimentation is based on the view of the simplest sort of statement as having, not subject/predicate form (as in Aristotle), but function/argument form. | |
| From: report of Gottlob Frege (Begriffsschrift [1879]) by Joan Weiner - Frege | |
| A reaction: This looks like being a crucial move into the modern world, where one piece of information is taken in and dealt with, as in computer procedures. Have educated people reorganised their minds along Fregean lines? |
| 18723 | We may correctly use 'not' without making the rule explicit [Wittgenstein] |
| Full Idea: Correct use does not imply the ability to make the rules explicit. Understanding 'not' is like understanding a move in chess. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B XII.1) |
| 18718 | Saying 'and' has meaning is just saying it works in a sentence [Wittgenstein] |
| Full Idea: When we say that the word 'and' has meaning what we mean is that it works in a sentence and is not just a flourish. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B VIII.2) |
| 18727 | A person's name doesn't mean their body; bodies don't sit down, and their existence can be denied [Wittgenstein] |
| Full Idea: The meaning of the words 'Professor Moore' is not a certain human body, because we do not say that the meaning sits on the sofa, and the words occur in the proposition 'Professor Moore does not exist'. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B Easter) | |
| A reaction: Brilliant. Love it. Kripke ending up denying the existence of 'meanings'. |
| 9950 | A quantifier is a second-level predicate (which explains how it contributes to truth-conditions) [Frege, by George/Velleman] |
| Full Idea: The contribution of the quantifier to the truth conditions of sentences of which it is a part cannot be adequately explained if it is treated as other than a second-level predicate (for instance, if it is viewed as name). | |
| From: report of Gottlob Frege (Begriffsschrift [1879]) by A.George / D.J.Velleman - Philosophies of Mathematics Ch.2 | |
| A reaction: They suggest that this makes it something like a 'property of properties'. With this account it becomes plausible to think of numbers as quantifiers (since they do, after all, specify quantities). |
| 9991 | For Frege the variable ranges over all objects [Frege, by Tait] |
| Full Idea: For Frege the variable ranges over all objects. | |
| From: report of Gottlob Frege (Begriffsschrift [1879]) by William W. Tait - Frege versus Cantor and Dedekind XII | |
| A reaction: The point is that Frege had not yet seen the necessity to define the domain of quantification, and this leads him into various difficulties. |
| 10536 | Frege's domain for variables is all objects, but modern interpretations first fix the domain [Dummett on Frege] |
| Full Idea: For Frege there is no need to specify the domain of the individual variables, which is taken as the totality of all objects. This contrasts with the standard notion of an interpretation, which demands that we first fix the domain. | |
| From: comment on Gottlob Frege (Begriffsschrift [1879]) by Michael Dummett - Frege Philosophy of Language (2nd ed) Ch.14 | |
| A reaction: What intrigues me is how domains of quantification shift according to context in ordinary usage, even in mid-sentence. I ought to go through every idea in this database, specifying its domain of quantification. Any volunteers? |
| 7730 | Frege introduced quantifiers for generality [Frege, by Weiner] |
| Full Idea: In order to express generality, Frege introduced quantifier notation. | |
| From: report of Gottlob Frege (Begriffsschrift [1879]) by Joan Weiner - Frege | |
| A reaction: This is the birth of predicate logic, beloved of analytical philosophers (but of no apparent interest to phenomenalists, deconstructionists, existentialists?). Generality is what you get from induction (which is, of course, problematic). |
| 7742 | Frege reduced most quantifiers to 'everything' combined with 'not' [Frege, by McCullogh] |
| Full Idea: Frege treated 'everything' as basic, and suggested ways of recasting propositions containing other quantifiers so that this was the only one remaining. He recast 'something' as 'at least one thing', and defined this in terms of 'everything' and 'not'. | |
| From: report of Gottlob Frege (Begriffsschrift [1879]) by Gregory McCullogh - The Game of the Name 1.6 | |
| A reaction: Extreme parsimony seems highly desirable in logic as well as ontology, but it can lead to frustrations, especially over the crucial question of the existence of things quantified over. See Idea 6068. |
| 13824 | Proof theory began with Frege's definition of derivability [Frege, by Prawitz] |
| Full Idea: Frege's formal definition of derivability is perhaps the first investigation in general proof theory. | |
| From: report of Gottlob Frege (Begriffsschrift [1879]) by Dag Prawitz - Gentzen's Analysis of First-Order Proofs 2 n2 | |
| A reaction: In 'On General Proof Theory §1' Prawitz says "proof theory originated with Hilbert" in 1900. Presumably Frege offered a theory, and then Hilbert saw it as a general project. |
| 13609 | Frege produced axioms for logic, though that does not now seem the natural basis for logic [Frege, by Kaplan] |
| Full Idea: Frege's work supplied a set of axioms for logic itself, at least partly because it was a well-known way of presenting the foundations in other disciplines, especially mathematics, but it does not nowadays strike us as natural for logic. | |
| From: report of Gottlob Frege (Begriffsschrift [1879]) by David Kaplan - Dthat 5.1 | |
| A reaction: What Bostock has in mind is the so-called 'natural' deduction systems, which base logic on rules of entailment, rather than on a set of truths. The axiomatic approach uses a set of truths, plus the idea of possible contradictions. |
| 18738 | We don't get 'nearer' to something by adding decimals to 1.1412... (root-2) [Wittgenstein] |
| Full Idea: We say we get nearer to root-2 by adding further figures after the decimal point: 1.1412.... This suggests there is something we can get nearer to, but the analogy is a false one. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], Notes) |
| 18708 | Infinity is not a number, so doesn't say how many; it is the property of a law [Wittgenstein] |
| Full Idea: 'Infinite' is not an answer to the question 'How many?', since the infinite is not a number. ...Infinity is the property of a law, not of an extension. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], A VII.2) |
| 17855 | It may be possible to define induction in terms of the ancestral relation [Frege, by Wright,C] |
| Full Idea: Frege's account of the ancestral has made it possible, in effect, to define the natural numbers as entities for which induction holds. | |
| From: report of Gottlob Frege (Begriffsschrift [1879]) by Crispin Wright - Frege's Concept of Numbers as Objects 4.xix | |
| A reaction: This is the opposite of the approach in the Peano Axioms, where induction is used to define the natural numbers. |
| 10607 | Frege's logic has a hierarchy of object, property, property-of-property etc. [Frege, by Smith,P] |
| Full Idea: Frege's general logical system involves a type hierarchy, distinguishing objects from properties from properties-of-properties etc., with every item belonging to a determinate level. | |
| From: report of Gottlob Frege (Begriffsschrift [1879]) by Peter Smith - Intro to Gödel's Theorems 14.1 | |
| A reaction: The Theory of Types went on to apply this hierarchy to classes, where Frege's disastrous Basic Law V flattens the hierarchy of classes, putting them on the same level (Smith p.119) |
| 11008 | Existence is not a first-order property, but the instantiation of a property [Frege, by Read] |
| Full Idea: When Kant said that existence was not a property, what he meant was, according to Frege, that existence is not a first-order property - it is not a property of individuals but a property of properties, that the property has an instance. | |
| From: report of Gottlob Frege (Begriffsschrift [1879]) by Stephen Read - Thinking About Logic Ch.5 |
| 18737 | There are no positive or negative facts; these are just the forms of propositions [Wittgenstein] |
| Full Idea: There are no positive or negative facts. 'Positive' and 'negative' refer to the form of propositions, and not to the facts which verify or falsify them. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], C XIII) | |
| A reaction: Personally I think if we are going to allow the world to be full of 'facts', then there are negative, conjunctive, disjunctive and hypothetical facts. |
| 18715 | Using 'green' is a commitment to future usage of 'green' [Wittgenstein] |
| Full Idea: If I say this is green, I must say that other things are green too. I am committed to a future usage. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B VI.2) | |
| A reaction: This seems to suggest that the eternal verity of a universal concept is just a convention of stability in a language. |
| 18726 | For each necessity in the world there is an arbitrary rule of language [Wittgenstein] |
| Full Idea: To a necessity in the world there corresponds an arbitrary rule in language. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B XIV.2) | |
| A reaction: This seems to be hardcore logical positivism, making all necessities arbitrary. Compare Quine on the number of planets. |
| 18712 | Understanding is translation, into action or into other symbols [Wittgenstein] |
| Full Idea: Understanding is really translation, whether into other symbols or into action. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B I.5) | |
| A reaction: The second part of this sounds like pure pragmatism. To do is to understand? I doubt it. Do animals understand anything? |
| 18280 | We live in sense-data, but talk about physical objects [Wittgenstein] |
| Full Idea: The world we live in is the world of sense-data, but the world we talk about is the world of physical objects. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], p.82), quoted by J. Alberto Coffa - The Semantic Tradition from Kant to Carnap 13 'Verif' | |
| A reaction: I really like that one. Even animals, I surmise, think of objects quite differently from the way they immediately experience them. |
| 18729 | Part of what we mean by stating the facts is the way we tend to experience them [Wittgenstein] |
| Full Idea: There is no need of a theory to reconcile what we know about sense data and what we believe about physical objects, because part of what we mean by saying that a penny is round is that we see it as elliptical in such and such conditions. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], C III) | |
| A reaction: This is an interesting and cunning move to bridge the gap between our representations and reallity. We may surmise how a thing really is, but then be surprised by the sense-data we get from it. |
| 23957 | We often trust our intuitions as rational, despite their lack of reflection [Solomon] |
| Full Idea: We trust certain rational 'intuitions' in ourselves which dispense with reflection but seem to follow an indisputable logic. (note: it is thought ineffable because reflection is the paradigm of rationality. It is no less rational than reflection). | |
| From: Robert C. Solomon (The Passions [1976], 6.4) | |
| A reaction: [compressed] Solomon uses the example to support that emotion is part of rationality. Since this view of intuition is more or less mine (that intuition can be knowledge, when the justification is obscure), it seems to support his claim. |
| 18734 | If you remember wrongly, then there must be some other criterion than your remembering [Wittgenstein] |
| Full Idea: If you remember wrongly, then there must be some other criterion than your remembering. If you admit another test, then your memory itself is not the test. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], C VII) | |
| A reaction: If I fear that I am remembering some private solitary event wrongly, there is no other criterion to turn to, so I'm stuck. Sometimes dubious memories are all we have. |
| 18721 | Explanation and understanding are the same [Wittgenstein] |
| Full Idea: For us explanation and understanding are the same, understanding being the correlate of explanation. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B XI.2) | |
| A reaction: I'm not convinced that they are 'the same', but they are almost interdependent ideas. Strevens has a nice paper on this. |
| 18720 | Explanation gives understanding by revealing the full multiplicity of the thing [Wittgenstein] |
| Full Idea: An explanation gives understanding, ...but it cannot teach you understanding, it cannot create understanding. It makes further distinctions i.e. it increases multiplicity. When multiplicity is complete, then there is no further misunderstanding. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B X.3) | |
| A reaction: The thought seems to resemble Aristotle's idea of definition as gradual division of the subject. To understand is the dismantle the parts and lay them out before us. Wittgenstein was very interested in explanation at this time. |
| 18716 | A machine strikes us as being a rule of movement [Wittgenstein] |
| Full Idea: We are accustomed to look on a machine as the expression of a rule of movement. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B VII.2) | |
| A reaction: What a beautiful definition of a machine! I like this because it connects the two halves of my view of the 'essence' of a thing, as derived from Aristotle, as both a causal mechanism and an underlying principle. Cf Turing machines. |
| 18713 | If an explanation is good, the symbol is used properly in the future [Wittgenstein] |
| Full Idea: The criterion of an explanation is whether the symbol explained is used properly in the future. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B II.4) | |
| A reaction: This appears to be a pragmatic criterion for the best explanation. It presumably rests on his doctrine that meaning is use, so good explanation is understanding meanings. |
| 23943 | Distinguishing reason from passion is based on an archaic 'faculty' theory [Solomon] |
| Full Idea: The distinction between reason and passion is based on an archaic 'faculty' psychology of the human soul. | |
| From: Robert C. Solomon (The Passions [1976], Intro.2) | |
| A reaction: I like faculties, for philosophical purposes, as explanatory tools to account for our metaphysical and conceptual framework, but this point is well made. The danger is that we impose sharp divisions, where reality is more complex. |
| 18717 | Thought is an activity which we perform by the expression of it [Wittgenstein] |
| Full Idea: Thought is an activity which we perform by the expression of it, and lasts as long as the expression. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B VIII) | |
| A reaction: I take this to be an outmoded view of thought, which modern cognitive science has undermined, by showing how little of our thinking is actually conscious. |
| 23952 | I say bodily chemistry and its sensations have nothing to do with emotions [Solomon] |
| Full Idea: I shall be making the claim (sujectively) that the chemistry of the body and the sensations caused by that chemistry have nothing to do with the emotions. | |
| From: Robert C. Solomon (The Passions [1976], 4.1) | |
| A reaction: Surely an unexpected stabbing pain causes fear? Isn't pain supposed to trigger appropriate emotions? That is not to say that emotions are a feature of body chemistry. |
| 23954 | Emotions are judgements about ourselves, and our place in the world [Solomon] |
| Full Idea: An emotion is a basic judgement about our Selves and our place in the world, the projection of the values and ideals, structures and mythologies | |
| From: Robert C. Solomon (The Passions [1976], 5.3) | |
| A reaction: Solomon's main theory. What about the Frege-Geach problem - that I feel emotions (and judgements) about fictions and remote events, in which my personal concerns and involvement are zero? Presumably these emotions are parasitic on his primary type? |
| 23960 | Emotions are defined by their objects [Solomon] |
| Full Idea: Direction, scope and focus set the stage, but the specific object is what defines the emotion. | |
| From: Robert C. Solomon (The Passions [1976], 7.3) | |
| A reaction: This is presumably the main distinction between an emotion and a mood. He emphasises that the objects are subjective, rather than factual. |
| 23961 | The heart of an emotion is its judgement of values and morality [Solomon] |
| Full Idea: The heart of every emotion is its value judgements, its appraisals of gain and loss, its indictment of offences and its praise of virtue, its often Manichean judgement of 'good' and 'evil'. | |
| From: Robert C. Solomon (The Passions [1976], 7.6) | |
| A reaction: He adds blame and excuse. Some of our strongest emotions can just be identifications, rather than judgements, as when we learn of someone else's triumph or disaster. On the whole I agree, though. This is important for Aristotelian virtue theory. |
| 23965 | Emotions can be analysed under fifteen headings [Solomon] |
| Full Idea: Emotions can be analysed by direction, scope/focus, object, criteria, status, evaluations, responsibility, intersubjectivity, distance, mythology, desire, power, strategy. | |
| From: Robert C. Solomon (The Passions [1976], 8) | |
| A reaction: These are the headings Solomon actually applies in his breakdown of most of the main emotions. See his book for explanations of each of them. If people say philosophy makes no progress, I'd at least point to helpful thinking of this kind. |
| 23959 | Some emotions are externally directed, others internally [Solomon] |
| Full Idea: 'Outer-directed' emotions (such as fear) are about particular situations, objects, or other people. …The 'inner-directed' emotions (such as vanity or regret) take one's Self as their focal point. | |
| From: Robert C. Solomon (The Passions [1976], 7.1) | |
| A reaction: This is Solomon's own distinction. Some of the emotions he cites, such as vanity, seem to me more like long term virtues or vices, rather than emotions. He did say, though, that you can have emotions without feeling, such as long-term hate. |
| 23936 | It is only our passions which give our lives meaning [Solomon] |
| Full Idea: It is our passions, and our passions alone, which provide our lives with meaning. | |
| From: Robert C. Solomon (The Passions [1976], Pref) | |
| A reaction: This presumably entails that the lives of plants have no meaning. It also seems to be rather egotistical, since it is not clear why anyone else's life should have meaning for me, if I don't directly experience their passions. Interesting, though. |
| 23963 | Which emotions we feel depends on our sense of our own powers [Solomon] |
| Full Idea: An emotion depends on an estimation of our own power. If a lover is jealous they welcome confrontation, but if they are just envious they assume impotence from the start. | |
| From: Robert C. Solomon (The Passions [1976], 7.12) | |
| A reaction: This seems particularly true of politics, where the possibility (or not) of influencing events makes a huge difference. We can picture a huge variety of emotions when a fight breaks out in public. |
| 23946 | The passions are subjective, concerning what is important to me, rather than facts [Solomon] |
| Full Idea: The passions are uniquely subjective, although they sometimes pretend to have a certain objective status. They are not concerned with the world, but with my world. They are not concerned with 'the facts', but with what is important. | |
| From: Robert C. Solomon (The Passions [1976], Intro.5) | |
| A reaction: Values pick out what is 'important'. This idea sums up Solomon's rather solipsistic view of emotions. I accept that emotions are responses, rather than objective judgements, but there is objectivity in their social dimension. Why care about politics? |
| 23940 | Emotions are strategies for maximising our sense of dignity and self-esteem [Solomon] |
| Full Idea: Every emotion is a strategy, a purposive attempt to structure our world in such a way as to maximise our sense of personal dignity and self-esteem. | |
| From: Robert C. Solomon (The Passions [1976], Pref) | |
| A reaction: This is the main thesis of Solomon's book. There doesn't seem to be much to admire in what he takes to be our chief motivation. I would put a much more social spin on it - that our underlying urge is not self-promotion, but to fit into a community. |
| 23949 | Passions exist as emotions, moods and desires, which all generate meaning [Solomon] |
| Full Idea: There are three fundamental species passions - emotions, moods, and desires. …What all passions have in common is their ability to bestow meaning to the circumstances of our lives. | |
| From: Robert C. Solomon (The Passions [1976], 3.2) | |
| A reaction: Moods are said to be 'generalised emotions', where emotions are about something, and desires add objectives. Solomon criticises rigid divisions between mental faculties and states, but it is hard to disagree with this distinction. |
| 23956 | The Myth of the Passions says they are irrational, uncontrolled and damaging [Solomon] |
| Full Idea: The Myth of the Passions says emotions are irrational forces beyond our control, disruptive and stupid, unthinking and counterproductive, against our 'better interests', and often ridiculous. | |
| From: Robert C. Solomon (The Passions [1976], 6.4) | |
| A reaction: The Myth is very unlikely to be correct, for evolutionary reasons. How could there be a selection for a mental feature which distorts truths and leads to dangerous misjudgements? Most emotions motivate us to act successfully. So why do some run wild? |
| 23953 | Feeling is a superficial aspect of emotion, and may be indeterminate, or even absent [Solomon] |
| Full Idea: Feeling is the ornamentation of emotion, not its essence. ...For example, what is the difference in feeling between embarrassment and shame? …We may also experience an emotion like subdued anger or envy with no feeling. | |
| From: Robert C. Solomon (The Passions [1976], 4.2) | |
| A reaction: This is very persuasive, and supports the idea that what matters in an emotion is its content, rather than its phenomenology. He adds later that we are often mistaken about our own emotions. |
| 23964 | There are no 'basic' emotions, only socially prevalent ones [Solomon] |
| Full Idea: There are no 'basic' emotions, only those emotions which are prevalent in a particular society. This reduction to a small set makes it impossible to appreciate the richness of our emotional lives. | |
| From: Robert C. Solomon (The Passions [1976], 8) | |
| A reaction: He cites Descartes as a culprit, and John Watson's famous list of fear, dependency and rage. I think Solomon is probably right. He suggests that the lists are usually individualistic and negative. Individuals may have their private basics! |
| 23937 | It is reason which needs the anchorage of passions, rather than vice versa [Solomon] |
| Full Idea: It is not the passions who require the controls and rationalisations of reason. Rather, it is reason that requires the anchorage and earthy wisdom of the passions. | |
| From: Robert C. Solomon (The Passions [1976], Pref) | |
| A reaction: I like the second half of this. We don't just follow the winds of arguments; we decide into which of the many conflicting winds we should steer the rational arguments, and that needs passions. Only a fool doesn't rationally control their passions. |
| 23947 | Dividing ourselves into confrontational reason and passion destroys our harmonious whole [Solomon] |
| Full Idea: To divide the soul into reason and passion …divides us against ourselves, forcing us each to be defensively half a person, instead of a harmonious whole. | |
| From: Robert C. Solomon (The Passions [1976], 2.3) | |
| A reaction: This is the best aspect of Solomon's book. I'm not sure, though, how this works in practice. Should I allow the winds of emotion to alter the course of my reasoning, or stunt my feelings by always insisting that reason plays a part? That's too dualist! |
| 23958 | The supposed irrationality of our emotions is often tactless or faulty expression of them [Solomon] |
| Full Idea: What is often called the 'irrationality' of our emotions is rather the faulty timing or inept choice of their expressions. | |
| From: Robert C. Solomon (The Passions [1976], 6.4) | |
| A reaction: The irrationality can be pretty obvious when having a tantrum over trivia, or resenting some tiny slight, or falling in love with a dead film star. That said, his point is well made. |
| 18725 | A proposition draws a line around the facts which agree with it [Wittgenstein] |
| Full Idea: A proposition gives reality a degree of freedom; it draws a line round the facts which agree with it, and distinguishes them from those which do not. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B XIII.2) | |
| A reaction: This seems to be the idea of meaning as the range of truth conditions. Propositions as sets of possible worlds extends this into possible facts which agree with the proposition. Most facts neither agree nor disagree with some proposition. |
| 18728 | The meaning of a proposition is the mode of its verification [Wittgenstein] |
| Full Idea: The meaning of a proposition is the mode of its verification (and two propositions cannot have the same verification). | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], C I) | |
| A reaction: Does this mean that if two sentences have the same mode of verification, then they must be expressing the same proposition? I guess so. |
| 18705 | Words function only in propositions, like levers in a machine [Wittgenstein] |
| Full Idea: Words function only in propositions, like the levers in a machine. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], A I.4) | |
| A reaction: Hm. Consider the word 'tree'. Did you manage to do it? Was it just a noise? |
| 22280 | Frege's account was top-down and decompositional, not bottom-up and compositional [Frege, by Potter] |
| Full Idea: Frege's account was top-down, not bottom-up: he aimed to decompose and discern function-argument structure in already existing sentences, not to explain how those sentences acquired their meanings in the first place. | |
| From: report of Gottlob Frege (Begriffsschrift [1879]) by Michael Potter - The Rise of Analytic Philosophy 1879-1930 03 'Func' | |
| A reaction: This goes with the holistic account of meaning, which leads to Quine's gavagai and Kuhn's obfuscation of science. I recommend compositionality for everthing. |
| 18711 | A proposition is any expression which can be significantly negated [Wittgenstein] |
| Full Idea: Any affirmation can be negated: if it has sense to say p it also has sense to say ¬p. ...A proposition therefore is any expression which can be significantly negated. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], B I.2) | |
| A reaction: I'm not sure about 'therefore'. I'm thinking you would have to already grasp the proposition in order to apply his negation test. |
| 23944 | Emotions are our life force, and the source of most of our values [Solomon] |
| Full Idea: Emotions are the life force of the soul, the source of most of our values (not all: there is always hunger, thirst, and fatigue). | |
| From: Robert C. Solomon (The Passions [1976], Intro.4) | |
| A reaction: I am beginning to worry that Solomon's account is too individual and subjective. My personal values may derive from my emotions, but I think human and social values are based much more on objective observations and facts. We are social, not solipsists. |
| 23962 | Lovers adopt the interests of their beloved, rather than just valuing them [Solomon] |
| Full Idea: It is often said that love takes the interests of the lover as being more important than one's own; but here again we would rather say that love takes the lovers interests as its own. | |
| From: Robert C. Solomon (The Passions [1976], 7.9) | |
| A reaction: This is because he sees emotions as almost entirely self-centred, and almost never altruistic. To me the evolutionary picture suggest a more social view. Many people want the lives of their ex- to go well, without knowing their new interests. |
| 23941 | 'Absurdity' is just the result of our wrong choices in life [Solomon] |
| Full Idea: The 'absurdity of life' is nothing than our own unsatisfactory choices, typically of defensiveness and resentment, competition, and 'meaningless' routines. | |
| From: Robert C. Solomon (The Passions [1976], Pref) | |
| A reaction: He seems to have Camus particularly in mind. He sees love and co-operation as the cure. I sort of agree, but somewhere in all of our minds there lurks an abyss, with the good life looking like a distraction from it. |
| 23955 | Ideologies are mythologies which guide our actions [Solomon] |
| Full Idea: Mythologies become ideologies when we play a role in them, live in them, take action and take sides. | |
| From: Robert C. Solomon (The Passions [1976], 6.1) | |
| A reaction: This may well be a sceptical American attitude to ideology, since 'mythology' implies a fiction. But I think for most of us there exists the possibility of a good ideology, which correctly points us towards a better life. Dangerous things, though! |
| 18733 | Laws of nature are an aspect of the phenomena, and are just our mode of description [Wittgenstein] |
| Full Idea: The laws of nature are not outside phenomena. They are part of language and of our way of describing things; you cannot discuss them apart from their physical manifestation. | |
| From: Ludwig Wittgenstein (Lectures 1930-32 (student notes) [1931], C V C) | |
| A reaction: I suppose this amounts to a Humean regularity theory - that the descriptions pick out patterns in the manifestations. I like the initial claim that they are not external to phenomena. |
| 7741 | The predicate 'exists' is actually a natural language expression for a quantifier [Frege, by Weiner] |
| Full Idea: On Frege's logical analysis, the predicate 'exists' is actually a natural language expression for a quantifier. | |
| From: report of Gottlob Frege (Begriffsschrift [1879]) by Joan Weiner - Frege Ch.8 | |
| A reaction: However see Idea 6067, for McGinn's alternative view of quantifiers. In the normal conventions of predicate logic it may be that existence is treated as a quantifier, but that is not the same as saying that existence just IS a quantifier. |
