25 ideas
1922 | Spiritual qualities only become advantageous with the growth of wisdom [Plato] |
Full Idea: If virtue is a beneficial attribute of spirit, it must be wisdom; for spiritual qualities are not in themselves advantageous, but become so with wisdom…..Hence men cannot be good by nature. | |
From: Plato (Meno [c.385 BCE], 88c) | |
A reaction: Personally I haven't got any 'spiritual qualities', so I don't really understand this. |
11259 | How can you seek knowledge of something if you don't know it? [Plato] |
Full Idea: How will you aim to search for something you do not know at all? If you should meet with it, how will you know that this is the thing that you did not know? | |
From: Plato (Meno [c.385 BCE], 80d05) | |
A reaction: Vasilis Politis cites this as a nice example of the 'aporiai' (puzzles) which Aristotle said were the foundation of enquiry. Nowadays the problem is called the 'paradox of enquiry'. |
20219 | True opinions only become really valuable when they are tied down by reasons [Plato] |
Full Idea: True opinions are a fine thing and all they do is good, …but they escape from a man's mind, so they are not worth much until one ties them down by (giving) an account of the reason why. | |
From: Plato (Meno [c.385 BCE], 98a3) | |
A reaction: This gives justification the role of guarantee, stabilising and securing true beliefs (rather than triggering some new thing called 'knowledge'). |
5985 | Seeking and learning are just recollection [Plato] |
Full Idea: Seeking and learning are in fact nothing but recollection. | |
From: Plato (Meno [c.385 BCE], 81d) | |
A reaction: This is a prelude to the famous conversation with the slave boy about geometry. You don't have to follow Plato into the doctrine of reincarnation; this remark is a key slogan for all rationalists. As pupils in maths lessons, we pull knowledge from within. |
5986 | The slave boy learns geometry from questioning, not teaching, so it is recollection [Plato] |
Full Idea: The slave boy's knowledge of geometry will not come from teaching but from questioning; he will recover it for himself, and the spontaneous recovery of knowledge that is in him is recollection. | |
From: Plato (Meno [c.385 BCE], 85d) | |
A reaction: Of course, if maths and geometry are huge tautological axiom systems, we would expect to be able to derive them (with hints from a teacher) entirely from their axioms. It is not clear why we might be able to derive the truths of all nature a priori. |
1923 | As a guide to action, true opinion is as good as knowledge [Plato] |
Full Idea: True opinion is as good a guide as knowledge for the purpose of acting rightly. | |
From: Plato (Meno [c.385 BCE], 97b) | |
A reaction: This is the germ of Peirce's epistemology - that knowledge is an interesting theoretical concept, but opinion/belief is what matters, and most needs explanation. |
604 | Knowledge is mind and knowing 'cohabiting' [Lycophron, by Aristotle] |
Full Idea: Lycophron has it that knowledge is the 'cohabitation' (rather than participation or synthesis) of knowing and the soul. | |
From: report of Lycophron (fragments/reports [c.375 BCE]) by Aristotle - Metaphysics 1045b | |
A reaction: This sounds like a rather passive and inert relationship. Presumably knowing something implies the possibility of acting on it. |
1919 | You don't need to learn what you know, and how do you seek for what you don't know? [Plato] |
Full Idea: You could argue that a man cannot discover what he does know or what he doesn't. The first needs no discovery, and how do you begin looking for the second? | |
From: Plato (Meno [c.385 BCE], 80e) |
7352 | Jesus said learning was unnecessary, and only the spirit of the Law was needed [Jesus, by Johnson,P] |
Full Idea: Jesus was a learned Jew who said that learning was not necessary, who took the spirit and not the letter as the essence of the Law. | |
From: report of Jesus (reports [c.32]) by Paul Johnson - The History of the Jews Pt II | |
A reaction: This seems to me the perfect opposite of Socrates's intellectualism, offering the essence of morality as 'purity of heart', rather than careful thought about virtue or principles. On the whole I am with Socrates, but the idea is interesting. |
6289 | Love your enemies [Jesus] |
Full Idea: Love your enemies. | |
From: Jesus (reports [c.32]), quoted by St Matthew - 01: Gospel of St Matthew 05.44 | |
A reaction: The germ of this idea had been around for several hundred years, but this very forceful statement is perhaps Jesus' most distinctive contribution to moral thought. It has the same clarion call as the Stoic demand for pure virtue. What about deserving? |
6292 | Love thy neighbour as thyself [Jesus] |
Full Idea: Love thy neighbour as thyself. | |
From: Jesus (reports [c.32]), quoted by St Matthew - 01: Gospel of St Matthew 19.19 | |
A reaction: It would be stronger and better to say 'Love your neighbour, even if you don't love yourself'. Self-loathing and vicious hatred often go together. For once Jesus does not attach an instant heavenly reward to obedience of the command. |
5356 | Treat others as you would have them treat you [Jesus] |
Full Idea: All things whatsoever ye would that men should do to you, so ye even so to them: for this is the law and the prophets. | |
From: Jesus (reports [c.32]), quoted by St Matthew - 01: Gospel of St Matthew 07.12 | |
A reaction: A problem which probably didn't occur to Jesus and the prophets is that of masochists. Personally I like buying philosophy books, but most people have no such desire. The Rule needs restricting to the basics of pleasure and pain. |
6286 | Blessed are the merciful: for they shall obtain mercy [Jesus] |
Full Idea: Blessed are the merciful: for they shall obtain mercy. | |
From: Jesus (reports [c.32]), quoted by St Matthew - 01: Gospel of St Matthew 05.07 | |
A reaction: This appears to be a straightforward application of social contract morality, with God playing the role of Hobbes' absolute monarch. It highlights the uncomfortable fact at the heart of Christian morality, that the motivation for altruism is selfish. |
6290 | Except ye become as little children, ye shall not enter heaven [Jesus] |
Full Idea: Except ye be converted, and become as little children, ye shall not enter into the kingdom of heaven. | |
From: Jesus (reports [c.32]), quoted by St Matthew - 01: Gospel of St Matthew 18.03 | |
A reaction: The appeal of such purity of heart is undeniable, but essentially I dislike this remark. It is the opponent of education, reason, autonomy, responsibility, democracy and maturity. It confirms the view that religion is the opium of the people. |
1913 | Is virtue taught, or achieved by practice, or a natural aptitude, or what? [Plato] |
Full Idea: Is virtue something that can be taught, or does it come by practice, or is it a natural aptitude, or something else? | |
From: Plato (Meno [c.385 BCE], 70a) |
1921 | If virtue is a type of knowledge then it ought to be taught [Plato] |
Full Idea: If virtue is some sort of knowledge, then clearly it could be taught. | |
From: Plato (Meno [c.385 BCE], 87c) |
1927 | It seems that virtue is neither natural nor taught, but is a divine gift [Plato] |
Full Idea: If our discussion is right, virtue is acquired neither by nature nor by teaching. Whoever has it gets it by divine dispensation, without taking thought. | |
From: Plato (Meno [c.385 BCE], 99e) |
6287 | If you lust after a woman, you have committed adultery [Jesus] |
Full Idea: Whosoever look on a woman to lust after her hath committed adultery with her already in his heart. | |
From: Jesus (reports [c.32]), quoted by St Matthew - 01: Gospel of St Matthew 05.28 | |
A reaction: Compare Democritus, Idea 503. Literally this idea seems absurd, but it is also at the heart of Greek virtue theory. Aristotle (Idea 34) defines virtue as an activity 'of the soul', not an action in the world. Excellence has become purity of soul. |
1916 | Even if virtues are many and various, they must have something in common to make them virtues [Plato] |
Full Idea: Even if virtues are many and various, at least they all have some common character which makes them all virtues. | |
From: Plato (Meno [c.385 BCE], 72c) |
1918 | How can you know part of virtue without knowing the whole? [Plato] |
Full Idea: Does anyone know what a part of virtue is without knowing the whole? | |
From: Plato (Meno [c.385 BCE], 79c) |
6285 | Blessed are the meek; for they shall inherit the earth [Jesus] |
Full Idea: Blessed are the meek; for they shall inherit the earth. | |
From: Jesus (reports [c.32]), quoted by St Matthew - 01: Gospel of St Matthew 05.05 | |
A reaction: If they are truly meek, why would they want to inherit the earth? This is the classic statement of Nietzsche's 'inversion of values', where the qualities of a good slave are elevated above those of the greatest human beings. |
6288 | Don't resist evil, but turn the other cheek [Jesus] |
Full Idea: Ye have heard it said, An eye for an eye, and a tooth for a tooth; But I say unto you, That ye resist not evil, but whosoever shall smite thee on thy right cheek, turn to him the other also. | |
From: Jesus (reports [c.32]), quoted by St Matthew - 01: Gospel of St Matthew 05.38-9 | |
A reaction: Compare Socrates, Idea 346. The viciousness of many Hollywood movies is that they set up a character as thoroughly evil so that we can have the pleasure of watching him pulverised. On the whole, Jesus gives bad advice. 'Doormats' in game theory. |
6293 | It is almost impossible for the rich to go to heaven [Jesus] |
Full Idea: It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God. | |
From: Jesus (reports [c.32]), quoted by St Matthew - 01: Gospel of St Matthew 19.24 | |
A reaction: Aristotle and others (Margaret Thatcher) have observed that you cannot practise charity if you are poor. Jesus implies that the human race should remain in poverty. No wonder autocratic medieval rulers taught Christianity to peasants. Cf. Matt 25.30. |
6291 | No one is good except God [Jesus] |
Full Idea: Why callest thou me good? There is none good but one, that is, God. | |
From: Jesus (reports [c.32]), quoted by St Matthew - 01: Gospel of St Matthew 19.17 | |
A reaction: This remark raises the problem that if God is good, there must be some separate moral standard by which he can be judged good. What is that standard? It is related to the problem of whether Plato's Form of the Beautiful is itself beautiful. |
7351 | Jesus turned the ideas of Hillel into a theology reduced to its moral elements [Jesus, by Johnson,P] |
Full Idea: Jesus was a member of the school of Hillel the Elder, and may have sat under him. He repeated some of the sayings of Hillel, ...and turned his ideas into a moral theology, stripping the law of all but its moral and ethical elements. | |
From: report of Jesus (reports [c.32]) by Paul Johnson - The History of the Jews Pt II | |
A reaction: The crucial move, it seems to me, is to strip Judaism of its complexity, and reduce it to very simple moral maxims, which means that ordinary illiterate people no longer need priests to understand and follow it. Jesus was, above all, a great teacher. |
