3067 | A philosopher should have principles ready for understanding, like a surgeon with instruments [Aurelius] |
Full Idea: As physicians have always their instruments and knives ready for cases which suddenly require their skill, so should you have principles ready for the understanding of things divine and human. | |
From: Marcus Aurelius (The Meditations (To Himself) [c.170], 3.13) | |
A reaction: Nice. Philosophy is the training ground where wisdom and good living are made possible, but it cannot be a substitute for living. |
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. |
3072 | Everything is changing, including yourself and the whole universe [Aurelius] |
Full Idea: All things are changing; and you yourself are in continuous mutation and in a manner in continuous destruction, and the whole universe too. | |
From: Marcus Aurelius (The Meditations (To Himself) [c.170], 9.19) |
8824 | No one has defended translational phenomenalism since Ayer in 1940 [Ayer, by Kim] |
Full Idea: I know of no serious defence of 'translational phenomenalism' since Ayer's in 1940. | |
From: report of A.J. Ayer (The Foundations of Empirical Knowledge [1940]) by Jaegwon Kim - What is 'naturalized epistemology'? 303-4+n | |
A reaction: We can think of Ayer as a hero who explored how far extreme empiricism would go. We still have anti-realists who are singing from a revised version of the song-sheet. Personally I am with Russell, that we must embrace the best explanation. |
3066 | Nothing is evil which is according to nature [Aurelius] |
Full Idea: Nothing is evil which is according to nature. | |
From: Marcus Aurelius (The Meditations (To Himself) [c.170], 2.17) | |
A reaction: A bit hopeful. Sounds tautological. I.e. anything which is agreed to be evil is probably immediately labelled as 'unnatural'. What would he agree was evil? |
3071 | Justice has no virtue opposed to it, but pleasure has temperance opposed to it [Aurelius] |
Full Idea: In the constitution of the rational animal I see no virtue which is opposed to justice; but I see a virtue which is opposed to pleasure, and that is temperance. | |
From: Marcus Aurelius (The Meditations (To Himself) [c.170], 8.39) | |
A reaction: There are plenty of hideous things opposed to justice, but presumably that immediately disqualifies them from being virtues. |
3069 | The art of life is more like the wrestler's than the dancer's [Aurelius] |
Full Idea: The art of life is more like the wrestler's than the dancer's. | |
From: Marcus Aurelius (The Meditations (To Himself) [c.170], 7.61) |
3065 | Humans are naturally made for co-operation [Aurelius] |
Full Idea: We are made for cooperation, like feet, like hands, like eyelids, like the rows of upper and lower teeth. To act against one another, then, is contrary to nature. | |
From: Marcus Aurelius (The Meditations (To Himself) [c.170], 2.1) |
15251 | The attribution of necessity to causation is either primitive animism, or confusion with logical necessity [Ayer] |
Full Idea: How are we to explain the word 'must' [about causation]? The answer is, I think, that it is either a relic of animism, or else reveals an inclination to treat causal connexion as if it were a form of logical necessity. | |
From: A.J. Ayer (The Foundations of Empirical Knowledge [1940], IV.18) | |
A reaction: The animism proposal just about makes sense (as a primitive feature of minds), but why would anyone, if they had the time and understanding, dream of treating a regular connection as a 'logical' necessity? |
