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!). |
3299 | In logic identity involves reflexivity (x=x), symmetry (if x=y, then y=x) and transitivity (if x=y and y=z, then x=z) [Baillie] |
Full Idea: In logic identity is an equivalence relation, which involves reflexivity (x=x), symmetry (if x=y, then y=x), and transitivity (if x=y and y=z, then x=z). | |
From: James Baillie (Problems in Personal Identity [1993], Intr p.4) |
22518 | The actual must be possible, because it occurred [Aristotle] |
Full Idea: Actual events are evidently possible, otherwise they would not have occurred. | |
From: Aristotle (The Poetics [c.347 BCE], 1451b18) | |
A reaction: [quoted online by Peter Adamson] Seems like common sense, but it's important to have Aristotle assert it. |
16566 | Poetry is more philosophic than history, as it concerns universals, not particulars [Aristotle] |
Full Idea: Poetry is something more philosophic and of graver import than history, since its statements are rather of universals, whereas those of history are singulars. | |
From: Aristotle (The Poetics [c.347 BCE], 1451b05) | |
A reaction: Hm. Characters in great novels achieve universality by being representated very particularly. Great depth of mind seems required to be a poet, but less so for a historian (though there is, I presume, no upward limit on the possible level of thought). |
