30 ideas
| 23825 | We seek truth only because it is good [Weil] |
| Full Idea: Truth is sought not because it is truth but because it is good. | |
| From: Simone Weil (Gravity and Grace (9 extracts) [1943], p.233) | |
| A reaction: A perfect instance of modern platonism. A few weird people seem to enjoy lying. Personally I cannot find enough content in the word 'good' in such claims. |
| 16477 | Asserting not-p is saying p is false [Russell] |
| Full Idea: When you do what a logician would call 'asserting not-p', you are saying 'p is false'. | |
| From: Bertrand Russell (An Inquiry into Meaning and Truth [1940], 5) | |
| A reaction: This is presumably classical logic. If we could label p as 'undetermined' (a third truth value), then 'not-p' might equally mean 'undetermined'. |
| 16484 | There are four experiences that lead us to talk of 'some' things [Russell] |
| Full Idea: Propositions about 'some' arise, in practice, in four ways: as generalisations of disjunctions; when an instance suggests compatibility of terms we thought incompatible; as steps to a generalisation; and in cases of imperfect memory. | |
| From: Bertrand Russell (An Inquiry into Meaning and Truth [1940], 5) | |
| A reaction: Modern logicians seem to have no interest in the question Russell is investigating here, but I love his attempt, however vague the result, to connect logic to real experience and thought. |
| 16486 | The physical world doesn't need logic, but the mental world does [Russell] |
| Full Idea: The non-mental world can be completely described without the use of any logical word, …but when it comes to the mental world, there are facts which cannot be mentioned without the use of logical words. | |
| From: Bertrand Russell (An Inquiry into Meaning and Truth [1940], 5) | |
| A reaction: He adds that logical words are not needed for physics, but are needed for psychology. I love Russell's interest in the psychology of logic (in defiance of the anti-psychologism of Frege). See also the ideas of Robert Hanna. |
| 2947 | Questions wouldn't lead anywhere without the law of excluded middle [Russell] |
| Full Idea: Without the law of excluded middle, we could not ask the questions that give rise to discoveries. | |
| From: Bertrand Russell (An Inquiry into Meaning and Truth [1940], c.p.88) |
| 16480 | A disjunction expresses indecision [Russell] |
| Full Idea: A disjunction is the verbal expression of indecision, or, if a question, of the desire to reach a decision. | |
| From: Bertrand Russell (An Inquiry into Meaning and Truth [1940], 5) | |
| A reaction: Russell is fishing here for Grice's conversational implicature. If you want to assert a simple proposition, you don't introduce it into an irrelevant disjunction, because that would have a particular expressive purpose. |
| 16479 | 'Or' expresses hesitation, in a dog at a crossroads, or birds risking grabbing crumbs [Russell] |
| Full Idea: Psychologically, 'or' corresponds to a state of hesitation. A dog waits at a fork in the road, to see which way you are going. For crumbs on a windowsill, birds behave in a manner we would express by 'shall I be brave, or go hungry?'. | |
| From: Bertrand Russell (An Inquiry into Meaning and Truth [1940], 5) | |
| A reaction: I love two facts here - first, that Russell wants to link the connective to the psychology of experience, and second, that a great logician wants to connect his logic to the minds of animals. |
| 16481 | 'Or' expresses a mental state, not something about the world [Russell] |
| Full Idea: When we assert 'p or q' we are in a state which is derivative from two previous states, and we express this state, not something about the world. | |
| From: Bertrand Russell (An Inquiry into Meaning and Truth [1940], 5) | |
| A reaction: His example: at a junction this road or that road goes to Oxford, but the world only contains the roads, not some state of 'this or that road'. He doesn't deny that in one sense 'p or q' tells you something about the world. |
| 16487 | Maybe the 'or' used to describe mental states is not the 'or' of logic [Russell] |
| Full Idea: It might be contended that, in describing what happens when a man believes 'p or q', the 'or' that we must use is not the same as the 'or' of logic. | |
| From: Bertrand Russell (An Inquiry into Meaning and Truth [1940], 5) | |
| A reaction: This seems to be the general verdict on Russell's enquiries in this chapter, but I love any attempt, however lacking in rigour etc., to connect formal logic to how we think, and thence to the world. |
| 16483 | Disjunction may also arise in practice if there is imperfect memory. [Russell] |
| Full Idea: Another situation in which a disjunction may arise is practice is imperfect memory. 'Either Brown or Jones told me that'. | |
| From: Bertrand Russell (An Inquiry into Meaning and Truth [1940], 5) |
| 16475 | A 'heterological' predicate can't be predicated of itself; so is 'heterological' heterological? Yes=no! [Russell] |
| Full Idea: A predicate is 'heterological' when it cannot be predicated of itself; thus 'long' is heterological because it is not a long word, but 'short' is homological. So is 'heterological' heterological? Either answer leads to a contradiction. | |
| From: Bertrand Russell (An Inquiry into Meaning and Truth [1940], 5) | |
| A reaction: [Grelling's Paradox] Yes: 'heterological' is heterological because it isn't heterological; No: it isn't, because it is. Russell says we therefore need a hierarchy of languages (types), and the word 'word' is outside the system. |
| 5044 | Reality must be made of basic unities, which will be animated, substantial points [Leibniz] |
| Full Idea: A multiplicity can only be made up of true unities, ..so I had recourse to the idea of a real and animated point, or an atom of substance which must embrace some element of form or of activity in order to make a complete being. | |
| From: Gottfried Leibniz (New System and Explanation of New System [1696], p.116) | |
| A reaction: This seems to be a combination of logical atomism and panpsychism. It has a certain charm, but looks like another example of these rationalist speculators overreaching themselves. |
| 16482 | All our knowledge (if verbal) is general, because all sentences contain general words [Russell] |
| Full Idea: All our knowledge about the world, in so far as it is expressed in words, is more or less general, because every sentence contains at least one word that is not a proper name, and all such words are general. | |
| From: Bertrand Russell (An Inquiry into Meaning and Truth [1940], 5) | |
| A reaction: I really like this, especially because it addresses the excessive reliance of some essentialists on sortals, categories and natural kinds, instead of focusing on the actual physical essences of individual objects. |
| 4758 | Naïve realism leads to physics, but physics then shows that naïve realism is false [Russell] |
| Full Idea: Naïve realism leads to physics, and physics, if true, shows that naïve realism is false. Therefore naïve realism, if true, is false, therefore it is false. | |
| From: Bertrand Russell (An Inquiry into Meaning and Truth [1940], p.13) | |
| A reaction: I'm inclined to agree with this, though once you have gone off and explored representation and sense data you may be driven back to naïve realism again. |
| 16476 | For simple words, a single experience can show that they are true [Russell] |
| Full Idea: So long as a man avoids words which are condensed inductions (such as 'dog'), and confines himself to words that can describe a single experience, it is possible for a single experience to show that his words are true. | |
| From: Bertrand Russell (An Inquiry into Meaning and Truth [1940], 5) | |
| A reaction: One might question whether a line can be drawn between the inductive and the non-inductive in this way. I'm inclined just to say that the simpler the proposition the less room there is for error in confirming it. |
| 16485 | Perception can't prove universal generalisations, so abandon them, or abandon empiricism? [Russell] |
| Full Idea: Propositions about 'some' may be proved empirically, but propositions about 'all' are difficult to know, and can't be proved unless such propositions are in the premisses. These aren't in perception, so forgo general propositions, or abandon empiricism? | |
| From: Bertrand Russell (An Inquiry into Meaning and Truth [1940], 5) | |
| A reaction: This is obviously related to the difficulty empiricists have with induction. You could hardly persuade logicians to give up the universal quantifier, because it is needed in mathematics. Do we actually know any universal empirical truths? |
| 5045 | No machine or mere organised matter could have a unified self [Leibniz] |
| Full Idea: By means of the soul or form, there is a true unity which is called the 'I' in us; a thing which could not occur in artificial machines, nor in the simple mass of matter, however organised it may be. | |
| From: Gottfried Leibniz (New System and Explanation of New System [1696], p.120) | |
| A reaction: I think the unity of consciousness and the unified Self are different phenomena. A wonderful remark about artificial intelligence for 1696! Note the idea of functionalism contained in 'organised'. Personally I see the brain as a 'mass of matter'. |
| 5046 | The soul does know bodies, although they do not influence one another [Leibniz] |
| Full Idea: I do not admit that the soul does not know bodies, although this knowledge arises without their influencing one another. | |
| From: Gottfried Leibniz (New System and Explanation of New System [1696], Reply 11) | |
| A reaction: He couldn't very well admit this without moving into pure idealism. Presumably it is like "I know her - she'll be in Harrods this morning". I wonder if Satan could steal my body, but my mind continue to believe it was still there? |
| 16478 | A mother cat is paralysed if equidistant between two needy kittens [Russell] |
| Full Idea: I once, to test the story of Buridan's Ass, put a cat exactly half-way between her two kittens, both too young to move: for a time she found the disjunction paralysing. | |
| From: Bertrand Russell (An Inquiry into Meaning and Truth [1940], 5) | |
| A reaction: Buridan's Ass is said to have starved between two equal piles of hay. Reason can't be the tie-breaker; reason obviously says 'choose one!', but intellectualism demands a reason for the one you choose. |
| 23826 | Beauty, goodness and truth are only achieved by applying full attention [Weil] |
| Full Idea: The authentic and pure values - truth, beauty and goodness - in the activity of a human being are the result of one and same act, a certain application of the full attention to the object. Teaching should only aim to train the attention for such an act. | |
| From: Simone Weil (Gravity and Grace (9 extracts) [1943], p.234) | |
| A reaction: A distinctive Weil idea, that absorbed 'attention' produces almost mystical results. I am not convinced that a great still life painter (than which there is no higher criterion of attention) achieves contact with goodness thereby. But attention is good! |
| 23833 | The good is a nothingness, and yet real [Weil] |
| Full Idea: The good seems to us a nothingness, since there is no thing that is good. But this nothingness is not unreal. | |
| From: Simone Weil (Gravity and Grace (9 extracts) [1943], p.278) | |
| A reaction: A neat move in the notoriously difficult platonic problem of specifying the actual nature of the good. |
| 23808 | There are two goods - the absolute good we want, and the reachable opposite of evil [Weil] |
| Full Idea: There are two goods - one which is the opposite of evil, and one which is the absolute. …That which we want is the absolute good. That which is within our reach is the good which is correlated with evil. | |
| From: Simone Weil (Gravity and Grace (9 extracts) [1943], p.142) | |
| A reaction: Elsewhere she seems in tune with the thought of Nietzsche (whom she despised) that good and evil are false social constructs which are quite different from healthy values. Weil, of course, sees the absolute as transcendent. |
| 23831 | The essence of power is illusory prestige [Weil] |
| Full Idea: Prestige, which is an illusion, is the very essence of power. | |
| From: Simone Weil (Gravity and Grace (9 extracts) [1943], p.255) | |
| A reaction: It is hard to maintain illusory prestige if there is no actual power behind it. |
| 23830 | A group is only dangerous if it endorses an abstract entity [Weil] |
| Full Idea: Any group which has not secreted an abstract entity will probably not be dangerous. | |
| From: Simone Weil (Gravity and Grace (9 extracts) [1943], p.255) | |
| A reaction: Written in the 1930s, the era of many political -isms. No group can be united if it lacks a clear label, and a few simple slogans. |
| 23809 | Our only social duty is to try to limit evil [Weil] |
| Full Idea: Our only duty with regard to the social is to try to limit the evil of it. | |
| From: Simone Weil (Gravity and Grace (9 extracts) [1943], p.143) | |
| A reaction: This is one of Weil's occasional remarks that have an anarchist flavour. I increasingly sympathise with this less idealistic view as I get older. |
| 23807 | The collective is the one and only object of false idolatry [Weil] |
| Full Idea: The Great Beast is the great object of idolatry, the only ersatz of God. …Only one thing can be taken as an end, for in relation to the human person it possesses a kind of transcendence: this is the collective. | |
| From: Simone Weil (Gravity and Grace (9 extracts) [1943], p.140) | |
| A reaction: [Society as the Great Beast is in Republic Bk 6] She is referring to both fascist and communist states. Weil seems to be a left-wing liberal, with a tendency towards anarchism, because her priority is the individual, not the group. |
| 23810 | Charity is the only love, and you can feel that for a country (a place with traditions), but not a nation [Weil] |
| Full Idea: We must not have any other love than charity. A nation cannot be an object of charity. But a country can be one - as an environment bearing traditions which are eternal. Every country can be that. | |
| From: Simone Weil (Gravity and Grace (9 extracts) [1943], p.146) | |
| A reaction: This definitely strikes a chord with me. I am English and British to the core, but don't feel any love at all for the current central institutions of the state. But I love my island, and its history, and its culture, and its style. |
| 23811 | If effort is from necessity rather than for a good, it is slavery [Weil] |
| Full Idea: To strive from necessity and not for some good - ...that is always slavery. | |
| From: Simone Weil (Gravity and Grace (9 extracts) [1943], p.180) | |
| A reaction: It is usual to see the possibility of anarchism as the starting point for political thinking, but I think for Weil the state of slavery has that role. |
| 5043 | To regard animals as mere machines may be possible, but seems improbable [Leibniz] |
| Full Idea: It seems to me that the opinion of those who transform or degrade the lower animals into mere machines, although it seems possible, is improbable, and even against the order of things. | |
| From: Gottfried Leibniz (New System and Explanation of New System [1696], p.116) | |
| A reaction: His target is Descartes. 'Against the order of things' seems to beg the question. What IS the order of things? Only a thorough-going dualist would worry about this question, and that isn't me. |
| 23765 | The soul is the intrinsic value of a human [Weil] |
| Full Idea: The soul is the human being considered as having a value in itself. | |
| From: Simone Weil (Gravity and Grace (9 extracts) [1943], p.294) | |
| A reaction: [from 'Gravity and Grace'] A rather modern view, treating the soul as an abstraction, rather than as an entity. |
