12268 | Contradiction is impossible [Antisthenes (I), by Aristotle] |
Full Idea: Antisthenes said that contradiction is impossible. | |
From: report of Antisthenes (Ath) (fragments/reports [c.405 BCE]) by Aristotle - Topics 104b21 | |
A reaction: Aristotle is giving an example of a 'thesis'. It should be taken seriously if a philosopher proposes it, but dismissed as rubbish if anyone else proposes it! No context is given for the remark. |
602 | Some fools think you cannot define anything, but only say what it is like [Antisthenes (I), by Aristotle] |
Full Idea: There is an application of that old chestnut of the cynic Antisthenes' followers (and other buffoons of that kind). Their claim was that a definition of what something is is impossible. You cannot define silver, though you can say it is like tin. | |
From: report of Antisthenes (Ath) (fragments/reports [c.405 BCE]) by Aristotle - Metaphysics 1043b |
13007 | Archimedes defined a straight line as the shortest distance between two points [Archimedes, by Leibniz] |
Full Idea: Archimedes gave a sort of definition of 'straight line' when he said it is the shortest line between two points. | |
From: report of Archimedes (fragments/reports [c.240 BCE]) by Gottfried Leibniz - New Essays on Human Understanding 4.13 | |
A reaction: Commentators observe that this reduces the purity of the original Euclidean axioms, because it involves distance and measurement, which are absent from the purest geometry. |
3157 | T.H.Huxley gave the earliest clear statement of epiphenomenalism [Huxley, by Rey] |
Full Idea: T.H.Huxley gave the earliest clear statement of epiphenomenalism. | |
From: report of T.H. Huxley (Method and Results [1893]) by Georges Rey - Contemporary Philosophy of Mind 3.1.1 | |
A reaction: This is, of course, impossible, because there can't be a clear statement of epiphenomenalism. |
3154 | Brain causes mind, but it doesn't seem that mind causes actions [Huxley] |
Full Idea: All states of consciousness are caused by molecular changes of brain substance. It seems to me there is no proof that any state of consciousness is the cause of change in the motion of the matter of the organism. | |
From: T.H. Huxley (Method and Results [1893], p.244), quoted by Georges Rey - Contemporary Philosophy of Mind 3.1.1 | |
A reaction: This sounds odd. Most people would say there is nothing more obvious than mental events causing actions. It certainly seems undeniable that actions are cause by the contents of thoughts, so a molecular account of intentional states is needed. |
1664 | I would rather go mad than experience pleasure [Antisthenes (I)] |
Full Idea: I would rather go mad than experience pleasure. | |
From: Antisthenes (Ath) (fragments/reports [c.405 BCE]), quoted by Diogenes Laertius - Lives of Eminent Philosophers 06.3 | |
A reaction: Did he actually prefer pain? If both experiences would drive him mad, it seems like a desire for death. I cannot understand why anyone is opposed to harmless pleasures. |
21385 | Antisthenes said virtue is teachable and permanent, is life's goal, and is like universal wealth [Antisthenes (I), by Long] |
Full Idea: The moral propositions of Antisthenes foreshadowed the Stoics: virtue can be taught and once acquired cannot be lost (fr.69,71); virtue is the goal of life (22); the sage is self-sufficient, since he has (by being wise) the wealth of all men (8o). | |
From: report of Antisthenes (Ath) (fragments/reports [c.405 BCE]) by A.A. Long - Hellenistic Philosophy 1 | |
A reaction: [He cites Caizzi for the fragments] The distinctive idea here is (I think) that once acquired virtue can never be lost. It sounds plausible, but I'm wondering why it should be true. Is it like riding a bicycle, or like learning to speak Russian? |
2631 | Antisthenes says there is only one god, which is nature [Antisthenes (I), by Cicero] |
Full Idea: Antisthenes says there is only one god, which is nature. | |
From: report of Antisthenes (Ath) (fragments/reports [c.405 BCE]) by M. Tullius Cicero - On the Nature of the Gods ('De natura deorum') I.32 |
