19693 | There is practical wisdom (for action), and theoretical wisdom (for deep understanding) [Aristotle, by Whitcomb] |
Full Idea: Aristotle takes wisdom to come in two forms, the practical and the theoretical, the former of which is good judgement about how to act, and the latter of which is deep knowledge or understanding. | |
From: report of Aristotle (works [c.330 BCE]) by Dennis Whitcomb - Wisdom Intro | |
A reaction: The interesting question is then whether the two are connected. One might be thoroughly 'sensible' about action, without counting as 'wise', which seems to require a broader view of what is being done. Whitcomb endorses Aristotle on this idea. |
15447 | We shouldn't always follow where the argument leads! [Lewis on Plato] |
Full Idea: There comes a time not to go on following where the argument leads! | |
From: comment on Plato (The Laws [c.348 BCE], 667b) by David Lewis - Against Structural Universals 'Variant' | |
A reaction: Lewis is a fine one to talk, since he follows argument that take him past innumerable incredulous stares of onlookers. |
9198 | It is no longer possible to be a sage, but we can practice the exercise of wisdom [Hadot] |
Full Idea: Personally I firmly believe, perhaps naively, that it is possible for modern man to live, not as a sage (sophos) - most of the ancients did not hold this to be possible - but as a practitioner of the ever-fragile exercise of wisdom. | |
From: Pierre Hadot (Philosophy as a way of life [1987], 7) | |
A reaction: It seems to me quite plausible that the philosophical life might yet become a widespread ideal, even though philosophers seem to still be sheltering from storms two thousand years after Plato gave us that image. |
243 | It is foolish to quarrel with the mind's own reasoning processes [Plato] |
Full Idea: When the soul quarrels with knowledge or opinion or reason, its natural ruling principles, you have there what I call 'folly'. | |
From: Plato (The Laws [c.348 BCE], 689b) |
9197 | The logos represents a demand for universal rationality [Hadot] |
Full Idea: The logos represents a demand for universal rationality. | |
From: Pierre Hadot (Philosophy as a way of life [1987], 3.3) | |
A reaction: That is at one end of the spectrum. At the other, in parts of 'Theaetetus', it is just a polite request to be given a few reasons, instead of a splattering of hopes and prejudices. |
1575 | For Aristotle logos is essentially the ability to talk rationally about questions of value [Roochnik on Aristotle] |
Full Idea: For Aristotle logos is the ability to speak rationally about, with the hope of attaining knowledge, questions of value. | |
From: comment on Aristotle (works [c.330 BCE]) by David Roochnik - The Tragedy of Reason p.26 |
1589 | Aristotle is the supreme optimist about the ability of logos to explain nature [Roochnik on Aristotle] |
Full Idea: Aristotle is the great theoretician who articulates a vision of a world in which natural and stable structures can be rationally discovered. His is the most optimistic and richest view of the possibilities of logos | |
From: comment on Aristotle (works [c.330 BCE]) by David Roochnik - The Tragedy of Reason p.95 |
241 | We ought to follow where the argument leads us [Plato] |
Full Idea: We ought to follow where the argument leads us. | |
From: Plato (The Laws [c.348 BCE], 667a) |
21264 | Mortals are incapable of being fully rational [Plato] |
Full Idea: We mustn't assume that mortal eyes will ever be able to look upon reason and get to know it adequately. | |
From: Plato (The Laws [c.348 BCE], 897d) | |
A reaction: This is in the context of the rational control of the whole Cosmos. I presume Plato would be flabbergasted by the findings of recent physics and cosmology. Did Kant believe that he was being completely rational about ethics? |
8200 | Aristotelian definitions aim to give the essential properties of the thing defined [Aristotle, by Quine] |
Full Idea: A real definition, according to the Aristotelian tradition, gives the essence of the kind of thing defined. Man is defined as a rational animal, and thus rationality and animality are of the essence of each of us. | |
From: report of Aristotle (works [c.330 BCE]) by Willard Quine - Vagaries of Definition p.51 | |
A reaction: Compare Idea 4385. Personally I prefer the Aristotelian approach, but we may have to say 'We cannot identify the essence of x, and so x cannot be defined'. Compare 'his mood was hard to define' with 'his mood was hostile'. |
4385 | Aristotelian definition involves first stating the genus, then the differentia of the thing [Aristotle, by Urmson] |
Full Idea: For Aristotle, to give a definition one must first state the genus and then the differentia of the kind of thing to be defined. | |
From: report of Aristotle (works [c.330 BCE]) by J.O. Urmson - Aristotle's Doctrine of the Mean p.157 | |
A reaction: Presumably a modern definition would just be a list of properties, but Aristotle seeks the substance. How does he define a genus? - by placing it in a further genus? |
251 | Truth has the supreme value, for both gods and men [Plato] |
Full Idea: Truth heads the list of all things good, for gods and men alike. | |
From: Plato (The Laws [c.348 BCE], 730c) |
13282 | Aristotle relativises the notion of wholeness to different measures [Aristotle, by Koslicki] |
Full Idea: Aristotle proposes to relativise unity and plurality, so that a single object can be both one (indivisible) and many (divisible) simultaneously, without contradiction, relative to different measures. Wholeness has degrees, with the strength of the unity. | |
From: report of Aristotle (works [c.330 BCE]) by Kathrin Koslicki - The Structure of Objects 7.2.12 | |
A reaction: [see Koslicki's account of Aristotle for details] As always, the Aristotelian approach looks by far the most promising. Simplistic mechanical accounts of how parts make wholes aren't going to work. We must include the conventional and conceptual bit. |
4730 | For Aristotle, the subject-predicate structure of Greek reflected a substance-accident structure of reality [Aristotle, by O'Grady] |
Full Idea: Aristotle apparently believed that the subject-predicate structure of Greek reflected the substance-accident nature of reality. | |
From: report of Aristotle (works [c.330 BCE]) by Paul O'Grady - Relativism Ch.4 | |
A reaction: We need not assume that Aristotle is wrong. It is a chicken-and-egg. There is something obvious about subject-predicate language, if one assumes that unified objects are part of nature, and not just conventional. |
13276 | The unmoved mover and the soul show Aristotelian form as the ultimate mereological atom [Aristotle, by Koslicki] |
Full Idea: Aristotle's discussion of the unmoved mover and of the soul confirms the suspicion that form, when it is not thought of as the object represented in a definition, plays the role of the ultimate mereological atom within his system. | |
From: report of Aristotle (works [c.330 BCE]) by Kathrin Koslicki - The Structure of Objects 6.6 | |
A reaction: Aristotle is concerned with which things are 'divisible', and he cites these two examples as indivisible, but they may be too unusual to offer an actual theory of how Aristotle builds up wholes from atoms. He denies atoms in matter. |
13277 | The 'form' is the recipe for building wholes of a particular kind [Aristotle, by Koslicki] |
Full Idea: Thus in Aristotle we may think of an object's formal components as a sort of recipe for how to build wholes of that particular kind. | |
From: report of Aristotle (works [c.330 BCE]) by Kathrin Koslicki - The Structure of Objects 7.2.5 | |
A reaction: In the elusive business of pinning down what Aristotle means by the crucial idea of 'form', this analogy strikes me as being quite illuminating. It would fit DNA in living things, and the design of an artifact. |
21259 | To grasp a thing we need its name, its definition, and what it really is [Plato] |
Full Idea: There are three elements in any given thing: the first is what the object actually is, the second is the definition of this, and the third is the name. | |
From: Plato (The Laws [c.348 BCE], 895d) | |
A reaction: I take the importance of this to be its distinction between what it is, and the definition of what it is. Aristotle maintains this distinction, but some modern Aristotelians seem to get the confused. Plato worried a lot more about names than we do. |
5991 | For Aristotle, knowledge is of causes, and is theoretical, practical or productive [Aristotle, by Code] |
Full Idea: Aristotle thinks that in general we have knowledge or understanding when we grasp causes, and he distinguishes three fundamental types of knowledge - theoretical, practical and productive. | |
From: report of Aristotle (works [c.330 BCE]) by Alan D. Code - Aristotle | |
A reaction: Productive knowledge we tend to label as 'knowing how'. The centrality of causes for knowledge would get Aristotle nowadays labelled as a 'naturalist'. It is hard to disagree with his three types, though they may overlap. |
11239 | The notion of a priori truth is absent in Aristotle [Aristotle, by Politis] |
Full Idea: The notion of a priori truth is conspicuously absent in Aristotle. | |
From: report of Aristotle (works [c.330 BCE]) by Vassilis Politis - Aristotle and the Metaphysics 1.5 | |
A reaction: Cf. Idea 11240. |
23312 | Aristotle is a rationalist, but reason is slowly acquired through perception and experience [Aristotle, by Frede,M] |
Full Idea: Aristotle is a rationalist …but reason for him is a disposition which we only acquire over time. Its acquisition is made possible primarily by perception and experience. | |
From: report of Aristotle (works [c.330 BCE]) by Michael Frede - Aristotle's Rationalism p.173 | |
A reaction: I would describe this process as the gradual acquisition of the skill of objectivity, which needs the right knowledge and concepts to evaluate new experiences. |
16111 | Aristotle wants to fit common intuitions, and therefore uses language as a guide [Aristotle, by Gill,ML] |
Full Idea: Since Aristotle generally prefers a metaphysical theory that accords with common intuitions, he frequently relies on facts about language to guide his metaphysical claims. | |
From: report of Aristotle (works [c.330 BCE]) by Mary Louise Gill - Aristotle on Substance Ch.5 | |
A reaction: I approve of his procedure. I take intuition to be largely rational justifications too complex for us to enunciate fully, and language embodies folk intuitions in its concepts (especially if the concepts occur in many languages). |
16971 | Plato says sciences are unified around Forms; Aristotle says they're unified around substance [Aristotle, by Moravcsik] |
Full Idea: Plato's unity of science principle states that all - legitimate - sciences are ultimately about the Forms. Aristotle's principle states that all sciences must be, ultimately, about substances, or aspects of substances. | |
From: report of Aristotle (works [c.330 BCE], 1) by Julius Moravcsik - Aristotle on Adequate Explanations 1 |
11243 | Aristotelian explanations are facts, while modern explanations depend on human conceptions [Aristotle, by Politis] |
Full Idea: For Aristotle things which explain (the explanantia) are facts, which should not be associated with the modern view that says explanations are dependent on how we conceive and describe the world (where causes are independent of us). | |
From: report of Aristotle (works [c.330 BCE]) by Vassilis Politis - Aristotle and the Metaphysics 2.1 | |
A reaction: There must be some room in modern thought for the Aristotelian view, if some sort of robust scientific realism is being maintained against the highly linguistic view of philosophy found in the twentieth century. |
3320 | Aristotle's standard analysis of species and genus involves specifying things in terms of something more general [Aristotle, by Benardete,JA] |
Full Idea: The standard Aristotelian doctrine of species and genus in the theory of anything whatever involves specifying what the thing is in terms of something more general. | |
From: report of Aristotle (works [c.330 BCE]) by José A. Benardete - Metaphysics: the logical approach Ch.10 |
12000 | Aristotle regularly says that essential properties explain other significant properties [Aristotle, by Kung] |
Full Idea: The view that essential properties are those in virtue of which other significant properties of the subjects under investigation can be explained is encountered repeatedly in Aristotle's work. | |
From: report of Aristotle (works [c.330 BCE]) by Joan Kung - Aristotle on Essence and Explanation IV | |
A reaction: What does 'significant' mean here? I take it that the significant properties are the ones which explain the role, function and powers of the object. |
21260 | Soul is what is defined by 'self-generating motion' [Plato] |
Full Idea: The entity which we call 'soul' is precisely that which is defined by the expression 'self-generating motion'. | |
From: Plato (The Laws [c.348 BCE], 896a) | |
A reaction: We may suspect that he defines soul in this way for a particular context, aimed at proving the existence of a First Mover. He must think there is more to soul than the generation of movement. |
276 | My individuality is my soul, which carries my body around [Plato] |
Full Idea: While I am alive I have nothing to thank for my individuality except my soul, whereas my body is just the likeness that I carry around with me. | |
From: Plato (The Laws [c.348 BCE], 959a) |
23300 | Aristotle and the Stoics denied rationality to animals, while Platonists affirmed it [Aristotle, by Sorabji] |
Full Idea: Aristotle, and also the Stoics, denied rationality to animals. …The Platonists, the Pythagoreans, and some more independent Aristotelians, did grant reason and intellect to animals. | |
From: report of Aristotle (works [c.330 BCE]) by Richard Sorabji - Rationality 'Denial' | |
A reaction: This is not the same as affirming or denying their consciousness. The debate depends on how rationality is conceived. |
11240 | The notion of analytic truth is absent in Aristotle [Aristotle, by Politis] |
Full Idea: The notion of analytic truth is conspicuously absent in Aristotle. | |
From: report of Aristotle (works [c.330 BCE]) by Vassilis Politis - Aristotle and the Metaphysics 1.5 | |
A reaction: Cf. Idea 11239. |
249 | People who value beauty above virtue insult the soul by placing the body above it [Plato] |
Full Idea: When a man values beauty above virtue, the disrespect he shows his soul is total and fundamental, because he argues that the body is more to be honoured than the soul. | |
From: Plato (The Laws [c.348 BCE], 727e) |
6559 | Aristotle never actually says that man is a rational animal [Aristotle, by Fogelin] |
Full Idea: To the best of my knowledge (and somewhat to my surprise), Aristotle never actually says that man is a rational animal; however, he all but says it. | |
From: report of Aristotle (works [c.330 BCE]) by Robert Fogelin - Walking the Tightrope of Reason Ch.1 | |
A reaction: When I read this I thought that this database would prove Fogelin wrong, but it actually supports him, as I can't find it in Aristotle either. Descartes refers to it in Med.Two. In Idea 5133 Aristotle does say that man is a 'social being'. But 22586! |
265 | An action is only just if it is performed by someone with a just character and outlook [Plato] |
Full Idea: The description 'just' is applicable only to the benefit conferred or injury inflicted by someone with a just character and outlook. | |
From: Plato (The Laws [c.348 BCE], 862b) | |
A reaction: How should we describe the occasional administering of good justice by a generally wicked judge. Greeks focus on character, but moderns focus on actions. |
269 | Attempted murder is like real murder, but we should respect the luck which avoided total ruin [Plato] |
Full Idea: An attempted murder should be treated like a successful one, but with respect shown for the luck which saved him from total ruin. | |
From: Plato (The Laws [c.348 BCE], 877a) | |
A reaction: The earliest reference to moral luck, I think. 'Repect' sounds vague, but it is asking judges to 'take it into consideration', which is quite practical. Attempted murderers are just as dangerous. |
9196 | The pleasure of existing is the only genuine pleasure [Hadot] |
Full Idea: For epicureans, the only genuine pleasure there is is the pleasure of existing. | |
From: Pierre Hadot (Philosophy as a way of life [1987], 3.1) | |
A reaction: I don't know Hadot's source for this claim, but it is a nice idea, which I shall endeavour to incorporate into my own attitude to daily living. I'm not quite clear, though, why the pleasure of music is not a 'genuine' one. |
240 | It would be strange if the gods rewarded those who experienced the most pleasure in life [Plato] |
Full Idea: It would be strange if the gods gave the greatest rewards in heaven to those who led the most pleasant life, rather than the most just. | |
From: Plato (The Laws [c.348 BCE], 662c) | |
A reaction: All of philosophy is just footnotes to Plato.... See Idea 1454. |
264 | The conquest of pleasure is the noblest victory of all [Plato] |
Full Idea: The conquest of pleasure is the noblest victory of all. | |
From: Plato (The Laws [c.348 BCE], 840c) | |
A reaction: Plato's puritanical streak. Even Aristotle doesn't agree with this. Self-control does not imply conquest of pleasure. Has a good professional wine taster conquered pleasure? |
4332 | Virtue is a concord of reason and emotion, with pleasure and pain trained to correct ends [Plato] |
Full Idea: Virtue is the general concord of reason and emotion, but there is one key element, which is the correct formation of our feelings of pleasure and pain, which makes us hate what we ought to hate, and love what we ought to love. | |
From: Plato (The Laws [c.348 BCE], 653c) | |
A reaction: An important truth, taken up by Aristotle. To see another person humiliated gives some people pleasure and other people pain. |
248 | A serious desire for moral excellence is very rare indeed [Plato] |
Full Idea: People who are anxious to attain moral excellence with all possible speed are pretty thin on the ground. | |
From: Plato (The Laws [c.348 BCE], 718e) |
253 | Every crime is the result of excessive self-love [Plato] |
Full Idea: The cause of each and every crime we commit is precisely this excessive love of ourselves. | |
From: Plato (The Laws [c.348 BCE], 731e) |
263 | The only worthwhile life is one devoted to physical and moral perfection [Plato] |
Full Idea: A life devoted to every physical perfection and every moral virtue is the only life worth the name. | |
From: Plato (The Laws [c.348 BCE], 807c) |
235 | Virtue is the aim of all laws [Plato] |
Full Idea: Virtue is the aim of the laws the legislator lays down. | |
From: Plato (The Laws [c.348 BCE], 631a) |
277 | The Guardians must aim to discover the common element in the four cardinal virtues [Plato] |
Full Idea: The guardians of the state should aim to get an exact idea of the common element in all the four virtues. | |
From: Plato (The Laws [c.348 BCE], 965d) |
254 | Excessive laughter and tears must be avoided [Plato] |
Full Idea: Excessive laughter and tears must be avoided. | |
From: Plato (The Laws [c.348 BCE], 732c) |
266 | Injustice is the mastery of the soul by bad feelings, even if they do not lead to harm [Plato] |
Full Idea: My general description of injustice is this: the mastery of the soul by anger, fear, pleasure, pain, envy and desires, whether they lead to actual damage or not. | |
From: Plato (The Laws [c.348 BCE], 863e) |
242 | The best people are produced where there is no excess of wealth or poverty [Plato] |
Full Idea: The community in which neither wealth nor poverty exists will produce the finest characters. | |
From: Plato (The Laws [c.348 BCE], 679b) |
256 | Virtue and great wealth are incompatible [Plato] |
Full Idea: Virtue and great wealth are quite incompatible. | |
From: Plato (The Laws [c.348 BCE], 742e) |
245 | Totalitarian states destroy friendships and community spirit [Plato] |
Full Idea: Excessively authoritarian government destroys all friendship and community of spirit in the state. | |
From: Plato (The Laws [c.348 BCE], 697d) |
239 | Education in virtue produces citizens who are active but obedient [Plato] |
Full Idea: Education in virtue produces a keen desire to become a perfect citizen who knows how to rule and be ruled as justice demands. | |
From: Plato (The Laws [c.348 BCE], 643e) |
1402 | Friendship is impossible between master and slave, even if they are made equal [Plato] |
Full Idea: Even if you proclaim that a master and a slave shall have equal status, friendship between them is inherently impossible. | |
From: Plato (The Laws [c.348 BCE], 757a) |
262 | Men and women should qualify equally for honours on merit [Plato] |
Full Idea: Men and women who have shown conspicuous merit should qualify for all honours without distinction of sex. | |
From: Plato (The Laws [c.348 BCE], 802a) |
236 | Sound laws achieve the happiness of those who observe them [Plato] |
Full Idea: Sound laws achieve the happiness of those who observe them. | |
From: Plato (The Laws [c.348 BCE], 631b) |
259 | Justice is granting the equality which unequals deserve [Plato] |
Full Idea: Justice consists of granting the 'equality' which unequals deserve to get. | |
From: Plato (The Laws [c.348 BCE], 757d) | |
A reaction: Beautifully simple, and hard to improve on. It shows the close link between equality and justice, but shows why they are not the same. The main debate about justice concerns the criteria for 'deserving'. |
11150 | It is the mark of an educated mind to be able to entertain an idea without accepting it [Aristotle] |
Full Idea: It is the mark of an educated mind to be able to entertain an idea without accepting it. | |
From: Aristotle (works [c.330 BCE]) | |
A reaction: The epigraph on a David Chalmers website. A wonderful remark, and it should be on the wall of every beginners' philosophy class. However, while it is in the spirit of Aristotle, it appears to be a misattribution with no ancient provenance. |
238 | Children's games should channel their pleasures into adult activity [Plato] |
Full Idea: We should use children's games to channel their pleasures and desires towards activities in which they will have to engage when they are adult. | |
From: Plato (The Laws [c.348 BCE], 643c) |
260 | Control of education is the key office of state, and should go to the best citizen [Plato] |
Full Idea: The Minister of Education is by far the most important of all the supreme offices of the state; the best all-round citizen in the state should be appointed. | |
From: Plato (The Laws [c.348 BCE], 765e) |
3037 | Aristotle said the educated were superior to the uneducated as the living are to the dead [Aristotle, by Diog. Laertius] |
Full Idea: Aristotle was asked how much educated men were superior to those uneducated; "As much," he said, "as the living are to the dead." | |
From: report of Aristotle (works [c.330 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 05.1.11 |
257 | Mathematics has the widest application of any subject on the curriculum [Plato] |
Full Idea: For domestic and public purposes, and all professional skills, no branch of a child's education has as big a range of applications as mathematics. | |
From: Plato (The Laws [c.348 BCE], 747a) |
4331 | Education is channelling a child's feelings into the right course before it understands why [Plato] |
Full Idea: I call 'education' the initial acquisition of virtue by the child, when the feelings of pleasure and affection, pain and hatred, are channelled in the right courses before he can understand the reason why. | |
From: Plato (The Laws [c.348 BCE], 653b) | |
A reaction: A precursor of Aristotle's view (Ethics 1104b11). A profound, simple and important insight. |
250 | The best way to educate the young is not to rebuke them, but to set a good example [Plato] |
Full Idea: The best way to educate the younger generation (as well as yourself) is not to rebuke them but patently to practise all your life what you preach to others. | |
From: Plato (The Laws [c.348 BCE], 729c) |
275 | Creation is not for you; you exist for the sake of creation [Plato] |
Full Idea: Creation is not for your benefit; you exist for the sake of the universe. | |
From: Plato (The Laws [c.348 BCE], 903c) |
8660 | There are potential infinities (never running out), but actual infinity is incoherent [Aristotle, by Friend] |
Full Idea: Aristotle developed his own distinction between potential infinity (never running out) and actual infinity (there being a collection of an actual infinite number of things, such as places, times, objects). He decided that actual infinity was incoherent. | |
From: report of Aristotle (works [c.330 BCE]) by Michèle Friend - Introducing the Philosophy of Mathematics 1.3 | |
A reaction: Friend argues, plausibly, that this won't do, since potential infinity doesn't make much sense if there is not an actual infinity of things to supply the demand. It seems to just illustrate how boggling and uncongenial infinity was to Aristotle. |
12058 | Aristotle's matter can become any other kind of matter [Aristotle, by Wiggins] |
Full Idea: Aristotle's conception of matter permits any kind of matter to become any other kind of matter. | |
From: report of Aristotle (works [c.330 BCE]) by David Wiggins - Substance 4.11.2 | |
A reaction: This is obviously crucial background information when we read Aristotle on matter. Our 92+ elements, and fixed fundamental particles, gives a quite different picture. Aristotle would discuss form and matter quite differently now. |
273 | Movement is transmitted through everything, and it must have started with self-generated motion [Plato] |
Full Idea: Motion is transmitted to innumerable things, and this must spring from some initial principle, which must be the change effected by self-generated motion. | |
From: Plato (The Laws [c.348 BCE], 895a) |
8004 | In 'The Laws', to obey the law is to be obey god [Plato, by MacIntyre] |
Full Idea: The divine is important in 'The Laws' because it is identified with law; to be obedient before the law is to be obedient before god. | |
From: report of Plato (The Laws [c.348 BCE]) by Alasdair MacIntyre - A Short History of Ethics Ch.6 | |
A reaction: Christian conservativism in a nutshell. Plato is rejecting his view in Euthyphro that piety (etc.) must precede the will of the gods. The obvious problem is bad laws, made by corrupt rulers. |
21261 | Self-moving soul has to be the oldest thing there is [Plato] |
Full Idea: Soul, being the source of motion, is the most ancient thing there is. | |
From: Plato (The Laws [c.348 BCE], 896b) | |
A reaction: Plato seems to assume that the First Mover must still exist, which doesn't follow from anything in the argument. The First Pusher could be dead before the last domino falls. Why can't activity be the default state of everything? |
21258 | The only possible beginning for the endless motions of reality is something self-generated [Plato] |
Full Idea: When the motion in reality is transmitted to thousands of things one after another, the entire sequence of their movements must surely spring from some initial principle, which can hardly be anything except the change effected by self-generated motion. | |
From: Plato (The Laws [c.348 BCE], 895a) | |
A reaction: This gives a domino picture of reality, with all of reality responding inertly to a first kick. Much better is to see self-generated motion in the active qualities of all matter, as seen in the sea of virtual subatomic particles at the smallest level. |
21257 | Self-generating motion is clearly superior to all other kinds of motion [Plato] |
Full Idea: We can't resist the conclusion that the motion which can generate itself is infinitely superior, and all the others are inferior to it. | |
From: Plato (The Laws [c.348 BCE], 894d) | |
A reaction: Who said you can't get values from facts! Not that the argument depends on superiority. There could be an inferior First Mover, as a bus driver is subservient to the passengers, or (my favourite) a head teacher is inferior to the pupils. |
274 | Soul must be the cause of all the opposites, such as good and evil or beauty and ugliness [Plato] |
Full Idea: Soul must be cause of good and evil, beauty and ugliness, justice and injustice, and all the opposites. | |
From: Plato (The Laws [c.348 BCE], 896d) |
21263 | If all the motions of nature reflect calculations of reason, then the best kind of soul must direct it [Plato] |
Full Idea: If the movement of the heavens and all that is in them reflects the motion and revolution and calculation of reason ...then clearly we have to admit that it is the best kind of soul that cares for the entire universe and directs it along the best path. | |
From: Plato (The Laws [c.348 BCE], 897c) | |
A reaction: Most of this passage reflects the cosmological argument - that without some initiating source natural events could not occur - but this slides into the design argument. So who designed mud (which is too inferior to have a Form)? |
278 | If astronomical movements are seen as necessary instead of by divine will, this leads to atheism [Plato] |
Full Idea: If a man studying astronomy sees events apparently happening by necessity rather than being directed by the intention of a benevolent will, he will turn into an atheist. | |
From: Plato (The Laws [c.348 BCE], 967a) |
21265 | The heavens must be full of gods, controlling nature either externally or from within [Plato] |
Full Idea: A soul or souls have been shown to be cause of all the phenomena, and whether it is by their living presence in matter that they direct all the heavens, or by some other means, we insist that these souls are gods. So 'everything is full of gods'. | |
From: Plato (The Laws [c.348 BCE], 899b) | |
A reaction: This seems to have little to do with the pagan gods on Olympus. It is also notably not monotheistic. It is somewhere between animism and panpsychism. Does he think the rivers and woods contain gods? Probably not. Just the orderly heavens. |
22729 | The concepts of gods arose from observing the soul, and the cosmos [Aristotle, by Sext.Empiricus] |
Full Idea: Aristotle said that the conception of gods arose among mankind from two originating causes, namely from events which concern the soul and from celestial phenomena. | |
From: report of Aristotle (works [c.330 BCE], Frag 10) by Sextus Empiricus - Against the Physicists (two books) I.20 | |
A reaction: The cosmos suggests order, and possible creation. What do events of the soul suggest? It doesn't seem to be its non-physical nature, because Aristotle is more of a functionalist. Puzzling. (It says later that gods are like the soul). |
21262 | There must be at least two souls controlling the cosmos, one doing good, the other the opposite [Plato] |
Full Idea: There must be more than one soul (not fewer than two) controlling movement and the heavens: that which does good, and that which has the opposite capacity. | |
From: Plato (The Laws [c.348 BCE], 896e) | |
A reaction: [Wording compressed - as often with the dialogues] This idea of controlling opposites is found in Empedocles. Presumably this good soul defers to the Form of the Good, as implied by the Euthyphro Question. |
