13310 | Wisdom does not lie in books, and unread people can also become wise [Seneca] |
Full Idea: What grounds could I possibly have for supposing that a person who has no acquaintance with books will never be a wise man? For wisdom does not lie in books. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 088) | |
A reaction: A useful warning to the likes of me, who may have retreated from the hurly-burly of the agora (see Callicles in Plato's 'Gorgias'), under the illusion that detachment is needed for wisdom. Maybe involvement is needed for wisdom. |
13295 | Wise people escape necessity by willing it [Seneca] |
Full Idea: There is nothing a wise man does reluctantly; he escapes necessity because he wills what necessity is going to force on him. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 054) | |
A reaction: He is discussing death in this letter. The difficulty here is sliding into fatalism. For instance, if you are informed that you have cancer, it is tempting to become 'wise' and will your own death, but lots of people fight it, and win. |
23367 | Even pointing a finger should only be done for a reason [Epictetus] |
Full Idea: Philosophy says it is not right even to stretch out a finger without some reason. | |
From: Epictetus (fragments/reports [c.57], 15) | |
A reaction: The key point here is that philosophy concerns action, an idea on which Epictetus is very keen. He rather despise theory. This idea perfectly sums up the concept of the wholly rational life (which no rational person would actually want to live!). |
13317 | Philosophy aims at happiness [Seneca] |
Full Idea: Philosophy takes as her aim the state of happiness. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 090) | |
A reaction: A startlingly forthright view. It seems to neglect what I take to be the main aim of philosophy, which is to achieve understanding. I presume true happiness would follow from that. Seneca must now explain why soporific pleasure is wrong. |
13293 | What philosophy offers humanity is guidance [Seneca] |
Full Idea: Shall I tell you what philosophy holds out for humanity? Counsel. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 048) | |
A reaction: See Quine for a flat modern denial of this claim (Idea 9764). There is a modern tendency to see ethics and political thought operating at a meta- or metameta- level. I take the main ethical theories to be very illuminating of real life. |
13309 | That something is a necessary condition of something else doesn't mean it caused it [Seneca] |
Full Idea: There's no reason for you to assume that, X being something without which Y could never have come about, Y came about as a result of the assistance of X. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 088) | |
A reaction: This thought originates with Carneades, reported by Cicero. This is a clear message to the likes of Mackie, who are in danger of thinking that giving the preconditions of something is sufficient to give its causes. |
13313 | Even philosophers have got bogged down in analysing tiny bits of language [Seneca] |
Full Idea: Even the philosophers have descended to the level of drawing distinctions between the uses of different syllables and discussing the proper meanings of prepositions and conjunctions. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 088) | |
A reaction: How wonderfully prescient! The vast industry of modern philosophy of language exactly fits Seneca's description. I don't quite share his contempt, of course, and I think Seneca would have a bit of sympathy with modern analysis (just a bit!). |
9570 | In Field's Platonist view, set theory is false because it asserts existence for non-existent things [Field,H, by Chihara] |
Full Idea: Field commits himself to a Platonic view of mathematics. The theorems of set theory are held to imply or presuppose the existence of things that don't in fact exist. That is why he believes that these theorems are false. | |
From: report of Hartry Field (Science without Numbers [1980]) by Charles Chihara - A Structural Account of Mathematics 11.1 | |
A reaction: I am sympathetic to Field, but this sounds wrong. A response that looks appealing is that maths is hypothetical ('if-thenism') - the truth is in the logical consequences, not in the ontological presuppositions. |
10260 | Logical consequence is defined by the impossibility of P and ¬q [Field,H, by Shapiro] |
Full Idea: Field defines logical consequence by taking the notion of 'logical possibility' as primitive. Hence q is a consequence of P if the conjunction of the items in P with the negation of q is not possible. | |
From: report of Hartry Field (Science without Numbers [1980]) by Stewart Shapiro - Philosophy of Mathematics 7.2 | |
A reaction: The question would then be whether it is plausible to take logical possibility as primitive. Presumably only intuition could support it. But then intuition will equally support natural and metaphysical possibilities. |
8958 | In Field's version of science, space-time points replace real numbers [Field,H, by Szabó] |
Full Idea: Field's nominalist version of science develops a version of Newtonian gravitational theory, where no quantifiers range over mathematical entities, and space-time points and regions play the role of surrogates for real numbers. | |
From: report of Hartry Field (Science without Numbers [1980]) by Zoltán Gendler Szabó - Nominalism 5.1 | |
A reaction: This seems to be a very artificial contrivance, but Field has launched a programme for rewriting science so that numbers can be omitted. All of this is Field's rebellion against the Indispensability Argument for mathematics. I sympathise. |
18221 | 'Metric' axioms uses functions, points and numbers; 'synthetic' axioms give facts about space [Field,H] |
Full Idea: There are two approaches to axiomatising geometry. The 'metric' approach uses a function which maps a pair of points into the real numbers. The 'synthetic' approach is that of Euclid and Hilbert, which does without real numbers and functions. | |
From: Hartry Field (Science without Numbers [1980], 5) |
8757 | The Indispensability Argument is the only serious ground for the existence of mathematical entities [Field,H] |
Full Idea: There is one and only one serious argument for the existence of mathematical entities, and that is the Indispensability Argument of Putnam and Quine. | |
From: Hartry Field (Science without Numbers [1980], p.5), quoted by Stewart Shapiro - Thinking About Mathematics 9.1 | |
A reaction: Personally I don't believe (and nor does Field) that this gives a good enough reason to believe in such things. Quine (who likes 'desert landscapes' in ontology) ends up believing that sets are real because of his argument. Not for me. |
18212 | Nominalists try to only refer to physical objects, or language, or mental constructions [Field,H] |
Full Idea: The most popular approach of nominalistically inclined philosophers is to try to reinterpret mathematics, so that its terms and quantifiers only make reference to, say, physical objects, or linguistic expressions, or mental constructions. | |
From: Hartry Field (Science without Numbers [1980], Prelim) | |
A reaction: I am keen on naturalism and empiricism, but only referring to physical objects is a non-starter. I think I favour constructions, derived from the experience of patterns, and abstracted, idealised and generalised. Field says application is the problem. |
10261 | The application of mathematics only needs its possibility, not its truth [Field,H, by Shapiro] |
Full Idea: Field argues that to account for the applicability of mathematics, we need to assume little more than the possibility of the mathematics, not its truth. | |
From: report of Hartry Field (Science without Numbers [1980]) by Stewart Shapiro - Philosophy of Mathematics 7.2 | |
A reaction: Very persuasive. We can apply chess to real military situations, provided that chess isn't self-contradictory (or even naturally impossible?). |
18218 | Hilbert explains geometry, by non-numerical facts about space [Field,H] |
Full Idea: Facts about geometric laws receive satisfying explanations, by the intrinsic facts about physical space, i.e. those laid down without reference to numbers in Hilbert's axioms. | |
From: Hartry Field (Science without Numbers [1980], 3) | |
A reaction: Hilbert's axioms mention points, betweenness, segment-congruence and angle-congruence (Field 25-26). Field cites arithmetic and geometry (as well as Newtonian mechanics) as not being dependent on number. |
9623 | Field needs a semantical notion of second-order consequence, and that needs sets [Brown,JR on Field,H] |
Full Idea: Field needs the notion of logical consequence in second-order logic, but (since this is not recursively axiomatizable) this is a semantical notion, which involves the idea of 'true in all models', a set-theoretic idea if there ever was one. | |
From: comment on Hartry Field (Science without Numbers [1980], Ch.4) by James Robert Brown - Philosophy of Mathematics | |
A reaction: Brown here summarises a group of critics. Field was arguing for modern nominalism, that actual numbers could (in principle) be written out of the story, as useful fictions. Popper's attempt to dump induction seemed to need induction. |
18215 | It seems impossible to explain the idea that the conclusion is contained in the premises [Field,H] |
Full Idea: No clear explanation of the idea that the conclusion was 'implicitly contained in' the premises was ever given, and I do not believe that any clear explanation is possible. | |
From: Hartry Field (Science without Numbers [1980], 1) |
18216 | Abstractions can form useful counterparts to concrete statements [Field,H] |
Full Idea: Abstract entities are useful because we can use them to formulate abstract counterparts of concrete statements. | |
From: Hartry Field (Science without Numbers [1980], 3) | |
A reaction: He defends the abstract statements as short cuts. If the concrete statements were 'true', then it seems likely that the abstract counterparts will also be true, which is not what fictionalism claims. |
18214 | Mathematics is only empirical as regards which theory is useful [Field,H] |
Full Idea: Mathematics is in a sense empirical, but only in the rather Pickwickian sense that is an empirical question as to which mathematical theory is useful. | |
From: Hartry Field (Science without Numbers [1980], 1) | |
A reaction: Field wants mathematics to be fictions, and not to be truths. But can he give an account of 'useful' that does not imply truth? Only in a rather dubiously pragmatist way. A novel is not useful. |
18210 | Why regard standard mathematics as truths, rather than as interesting fictions? [Field,H] |
Full Idea: Why regard the axioms of standard mathematics as truths, rather than as fictions that for a variety of reasons mathematicians have become interested in? | |
From: Hartry Field (Science without Numbers [1980], p.viii) |
18211 | You can reduce ontological commitment by expanding the logic [Field,H] |
Full Idea: One can often reduce one's ontological commitments by expanding one's logic. | |
From: Hartry Field (Science without Numbers [1980], p.ix) | |
A reaction: I don't actually understand this idea, but that's never stopped me before. Clearly, this sounds like an extremely interesting thought, and hence I should aspire to understand it. So I do aspire to understand it. First, how do you 'expand' a logic? |
8959 | Field presumes properties can be eliminated from science [Field,H, by Szabó] |
Full Idea: Field regards the eliminability of apparent reference to properties from the language of science as a foregone result. | |
From: report of Hartry Field (Science without Numbers [1980]) by Zoltán Gendler Szabó - Nominalism 5.1 n50 | |
A reaction: Field is a nominalist who also denies the existence of mathematics as part of science. He has a taste for ontological 'desert landscapes'. I have no idea what a property really is, so I think he is on to something. |
18213 | Abstract objects are only applicable to the world if they are impure, and connect to the physical [Field,H] |
Full Idea: To be able to apply any postulated abstract entities to the physical world, we need impure abstact entities, e.g. functions that map physical objects into pure abstract objects. | |
From: Hartry Field (Science without Numbers [1980], 1) | |
A reaction: I am a fan of 'impure metaphysics', and this pinpoints my reason very nicely. |
18222 | Beneath every extrinsic explanation there is an intrinsic explanation [Field,H] |
Full Idea: A plausible methodological principle is that underlying every good extrinsic explanation there is an intrinsic explanation. | |
From: Hartry Field (Science without Numbers [1980], 5) | |
A reaction: I'm thinking that Hartry Field is an Aristotelian essentialist, though I bet he would never admit it. |
13297 | To the four causes Plato adds a fifth, the idea which guided the event [Seneca] |
Full Idea: To the four Aristotelian causes Plato adds a fifth in the model - what he himself calls the 'idea' - this being what the sculptor had constantly before his eyes as he executed the intended work. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 065) | |
A reaction: A very interesting interpretation. I take the four 'causes' to be primarily the four 'explanations', and it exactly fits how we should understand Plato, as offer a crucial underlying explanation. The statue is Aristotle's example. |
13307 | If everything can be measured, try measuring the size of a man's soul [Seneca] |
Full Idea: Nothing's outside your scope when it comes to measurement. Well, if you're such an expert, measure a man's soul; tell me how large or how small that is. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 088) | |
A reaction: This is Descartes's non-spatial argument, which I take to be one of the four main props to his mind-body dualism. As always, it is expressed with beautiful concision by Seneca. |
9917 | 'Abstract' is unclear, but numbers, functions and sets are clearly abstract [Field,H] |
Full Idea: The term 'abstract entities' may not be entirely clear, but one thing that does seem clear is that such alleged entities as numbers, functions and sets are abstract. | |
From: Hartry Field (Science without Numbers [1980], p.1), quoted by JP Burgess / G Rosen - A Subject with No Object I.A.1.a | |
A reaction: Field firmly denies the existence of such things. Sets don't seem a great problem, if the set is a herd of elephants, but the null and singleton sets show up the difficulties. |
21399 | Referring to a person, and speaking about him, are very different [Seneca] |
Full Idea: It makes a very great difference whether you refer to the person directly, or speak about him. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 117.13), quoted by A.A. Long - Hellenistic Philosophy 4.3.2 | |
A reaction: We seem to think that the distinctiveness of reference was first spotted by Frege. Not so. |
13325 | Trouble in life comes from copying other people, which is following convention instead of reason [Seneca] |
Full Idea: One of the causes of the troubles that beset us is the way our lives are guided by the example of others; instead of being set to rights by reason we're seduced by convention. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 123) | |
A reaction: An interesting practical spin and critique of the standard metaethical idea that morality is just convention. If you think morality is convention, presumably your moral duty is to imitate your neighbours. Nice deconstruction. |
22239 | Humans acquired the concept of virtue from an analogy with bodily health and strength [Seneca, by Allen] |
Full Idea: Seneca held that human beings owe the original acquisition of the concept of virtue to an analogy with bodily health and strength | |
From: report of Seneca the Younger (Letters from a Stoic [c.60], 120.5) by James Allen - Soul's Virtue and the Health of the Body p.76 | |
A reaction: This is an unusual view, even for a stoic, but shows how close the concepts of health and virtue were. Notice that it is strength as well as health. Plato just emphasises mental and physical harmony. |
13294 | We know death, which is like before birth; ceasing to be and never beginning are the same [Seneca] |
Full Idea: I already know what death is like - it will be the same after me as it was before me. ..Only an utter idiot would think a lamp was worse off when it was put out than before it was lit. ..What does it matter whether you cease to be or never begin? | |
From: Seneca the Younger (Letters from a Stoic [c.60], 054) | |
A reaction: These sentiments are, interestingly, derived from the epicureans, rather than from the stoic tradition, but to us they probably look close together, where they looked like opponents at the time. |
13299 | Living is nothing wonderful; what matters is to die well [Seneca] |
Full Idea: There's nothing so very great about living - all your slaves and all the animals do it. What is, however, a great thing is to die in a manner which is honourable, enlightened and courageous. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 077) | |
A reaction: You get the feeling that Seneca actually thought suicide was better than a natural death. Did he actually seek his own death? It is an odd interpretation of his own stoic injunction to 'live according to nature'. |
13300 | It is as silly to lament ceasing to be as to lament not having lived in the remote past [Seneca] |
Full Idea: Wouldn't you think a man a prize fool if he burst into tears because he didn't live a thousand years ago? A man is such a fool for shedding tears because he isn't going to be alive a thousand years from now. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 077) | |
A reaction: These thoughts are traditional, dating back to Epicurus, but Seneca is exceptionally going at finding new variations and examples to reinforce the basic thought. |
13321 | Is anything sweeter than valuing yourself more when you find you are loved? [Seneca] |
Full Idea: Can anything be sweeter than to find that you are so dear to your wife that this makes you dearer to yourself? | |
From: Seneca the Younger (Letters from a Stoic [c.60], 104) | |
A reaction: Another lovely penetrating remark from Seneca. I suppose a symptom of low self-esteem might be 'why does she love someone as worthless as me?', but that would be unusual. |
13292 | Selfishness does not produce happiness; to live for yourself, live for others [Seneca] |
Full Idea: No one can lead a happy life if he thinks only of himself and turns everything to his own purposes. You should live for the other person if you wish to live for yourself. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 048) | |
A reaction: It is important to see this as a key aspect of the ancient aspiration to virtue. The end result is not far from Christianity. It is simplistic to see the quest for virtue as a crass self-obsessed quest for self-improvement. We are social. |
13303 | A man is as unhappy as he has convinced himself he is [Seneca] |
Full Idea: A man is as unhappy as he has convinced himself he is. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 078) | |
A reaction: Seneca is a very penetrating thinker about ordinary life - an aspect of philosophy which is nowadays totally neglected by the most eminent philosophers. |
13302 | Life is like a play - it is the quality that matters, not the length [Seneca] |
Full Idea: As it is with a play, so it is with life - what matters is not how long the acting lasts, but how good it is. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 077) | |
A reaction: A very nice epigram, culminating the wonderful Letter 77 on the subject of death. A play needs to be a decent length if it is to exhibit its qualities. It would be heartbreaking if all of Shakespeare's plays were just 20-minute sketches. |
13301 | We are scared of death - except when we are immersed in pleasure! [Seneca] |
Full Idea: You are scared of death - but how heedless of it you are while you are dealing with a dish of choice mushrooms! | |
From: Seneca the Younger (Letters from a Stoic [c.60], 077) | |
A reaction: A beautifully simple observation, from the greatest philosopher of death. Maybe hospices should concentrate on sex, drugs and rock and roll. |
13323 | The whole point of pleasure-seeking is novelty, and abandoning established ways [Seneca] |
Full Idea: The whole object of luxurious living is the delight it takes in irregular ways and in not merely departing from the correct course but going to the farthest point away from it, and in eventually even taking a stand diametrically opposed to it. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 122) | |
A reaction: A rather conservative and puritanical remark, but worthy of contemplation even for committed hedonists. It is just a sad facts that most pleasures diminish with familiarity. Small children make delightful remarks. Imagine if they repeated them. |
13318 | Nature doesn't give us virtue; we must unremittingly pursue it, as a training and an art [Seneca] |
Full Idea: Nature does not give a man virtue; the process of becoming a good man is an art. ...Virtue only comes to a character which has been thoroughly schooled and trained and brought to a pitch of perfection by unremitting practice. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 090) | |
A reaction: This is an important gloss from a leading stoic on the slogan of 'live according to nature'. One might say that the natural life must be 'tracked' (as Philip Larkin says we track happiness). The natural life is, above all, the rational life, for stoics. |
13324 | Living contrary to nature is like rowing against the stream [Seneca] |
Full Idea: For those who follow nature everything is easy and straightforward, whereas for those who fight against her life is just like rowing against the stream. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 102) | |
A reaction: A classic statement of the well-known stoic slogan, but expressed with Seneca's characteristic elegance. There is always a slight hidden of dubious fatalism in the slogan. 'Rage, rage, against the dying of the light!' - Dylan Thomas. |
13305 | Character is ruined by not looking back over our pasts, since the future rests on the past [Seneca] |
Full Idea: What really ruins our characters is the fact that none of us looks back over his life. We think a little about what we are going to do, and fail to think about what we have done, yet plans for the future depend on the past. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 083) | |
A reaction: One always assumes that writings about the wisdom of daily life will be one mass of clichés, but Seneca proves otherwise. With a pang I realise that I may be too guilty of not thinking about the past. I've even been proud of it. |
13308 | It's no good winning lots of fights, if you are then conquered by your own temper [Seneca] |
Full Idea: What's the use of overcoming opponent after opponent in the wrestling or boxing rings if you can be overcome by your temper? | |
From: Seneca the Younger (Letters from a Stoic [c.60], 088) | |
A reaction: He has such a nice way of presenting what might be traditional and commonplace ideas. If you see life as a battle, then you should think very carefully about who the opponents are - because they may be hiding within. |
13312 | Excessive curiosity is a form of intemperance [Seneca] |
Full Idea: To want to know more than is sufficient is a form of intemperance. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 088) | |
A reaction: This comes as a bit of a surprise, given the high value that philosophers place on knowledge. I'm reminded of Auberon Waugh's criticism of the Scots as a 'wildly over-educated people'. I think the problem is what you could have been doing instead. |
13315 | To govern used to mean to serve, not to rule; rulers did not test their powers over those who bestowed it [Seneca] |
Full Idea: In the Golden Age, to govern was to serve, not to rule. No one used to try out the extent of his power over those to whom he owed that power in the first place. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 090) | |
A reaction: I spent my professional career trying to persuade people that management should be a subjection to the managed. Wake up! The second half of this idea is the interesting bit - the temptation to just 'try out' your powers gets to them all. |
13322 | Both teachers and pupils should aim at one thing - the improvement of the pupil [Seneca] |
Full Idea: A person teaching and a person learning should have the same end in view: the improvement of the latter. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 108) | |
A reaction: [He cites a philospher called Attalus for this remark] This is worthy to be up in the hall of every educational institution in the world, and especially in the staff rooms. |
13290 | One joy of learning is making teaching possible [Seneca] |
Full Idea: Part of my joy in learning is that it puts me in a position to teach. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 006) | |
A reaction: This doesn't quite distinguish between bad learning and good learning, but I take a commitment to wanting to teach what you know as an essential part of wanting to know. |
13298 | Suicide may be appropriate even when it is not urgent, if there are few reasons against it [Seneca] |
Full Idea: There are many occasions on which a man should leave life not only bravely but for reasons which are not as pressing as they might be - the reasons which restrain us being not so pressing either. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 077) | |
A reaction: This is an interesting and startling claim from the great champion of suicide, who nobly and memorably committed suicide himself. But we all dread a loved one miscalculating Seneca's dialectic, and dying when living would have been better. |
13319 | If we control our own death, no one has power over us [Seneca] |
Full Idea: No one has power over us when death is in our own power. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 091) | |
A reaction: A classic slogan for the stoic view of suicide, an idea that crops up in Shakespeare's 'Julius Caesar'. He doesn't seem to have understood that they can take away your shoelaces. |
13320 | Sometimes we have a duty not to commit suicide, for those we love [Seneca] |
Full Idea: There are times when, however pressing one's reasons to the contrary, one's dying breath must be held back as it is passing one's lips, even if this is torture, simply out of consideration for one's dear ones. | |
From: Seneca the Younger (Letters from a Stoic [c.60], 104) | |
A reaction: This is, of course, a highly significant counterbalance to his normal acceptance of suicide. I wish anyone who is planning suicide would heed it. They have no idea how much suffering will usually result from their action. |
18223 | In theories of fields, space-time points or regions are causal agents [Field,H] |
Full Idea: According to theories that take the notion of a field seriously, space-time points or regions are fully-fledge causal agents. | |
From: Hartry Field (Science without Numbers [1980], n 23) |
18220 | Both philosophy and physics now make substantivalism more attractive [Field,H] |
Full Idea: In general, it seems to me that recent developments in both philosophy and physics have made substantivalism a much more attractive position than it once was. | |
From: Hartry Field (Science without Numbers [1980], 4) | |
A reaction: I'm intrigued as to what philosophical developments are involved in this. The arrival of fields is the development in physics. |
18219 | Relational space is problematic if you take the idea of a field seriously [Field,H] |
Full Idea: The problem of the relational view of space is especially acute in the context of physical theories that take the notion of a field seriously, e.g. classical electromagnetic theory. | |
From: Hartry Field (Science without Numbers [1980], 4) | |
A reaction: In the Leibniz-Clarke debate I sided with the Newtonian Clarke (defending absolute space), and it looks like modern science agrees with me. Nothing exists purely as relations. |
13311 | Does time exist on its own? Did anything precede it? Did it pre-exist the cosmos? [Seneca] |
Full Idea: Look how many questions there are on time. Does it have an existence of its own? Does anything exist prior to time, independently of it? Did it begin with the universe, or did it exist even before then? | |
From: Seneca the Younger (Letters from a Stoic [c.60], 088) | |
A reaction: I'm not sure that the questions have shifted or become any clearer after two thousand years, despite Einstein and co. Note that discussions of time were not initiated by Augustine. |
