291 | Don't assume that wisdom is the automatic consequence of old age [Plato] |
Full Idea: Don't assume that wisdom is the automatic consequence of old age. | |
From: Plato (Laches [c.381 BCE], 188b) | |
A reaction: I have taught teenagers who seemed to me wiser than nearly all the adults I have ever met. |
18948 | There is an object for every set of properties (some of which exist, and others don't) [Parsons,T, by Sawyer] |
Full Idea: According to Terence Parsons, there is an object corresponding to every set of properties. To some of those sets of properties there corresponds an object that exists, and to others there corresponds an object that does not exist (a nonexistent object). | |
From: report of Terence Parsons (Nonexistent Objects [1980]) by Sarah Sawyer - Empty Names 5 | |
A reaction: This I take to be the main source of the modern revival of Meinong's notorious view of objects (attacked by Russell). I always find the thought 'a round square is square' to be true, and in need of a truthmaker. But must a round square be non-triangular? |
579 | Cratylus said you couldn't even step into the same river once [Cratylus, by Aristotle] |
Full Idea: Cratylus was appalled that Heraclitus said you could not step twice into the same river, because it was already going too far to admit stepping into the same river once. | |
From: report of Cratylus (fragments/reports [c.425 BCE]) by Aristotle - Metaphysics 1010a | |
A reaction: Compare Idea 427. |
578 | Cratylus decided speech was hopeless, and his only expression was the movement of a finger [Cratylus, by Aristotle] |
Full Idea: Cratylus thought speech of any kind was radically inappropriate and that expression should be restricted exclusively to the movement of the finger. | |
From: report of Cratylus (fragments/reports [c.425 BCE]) by Aristotle - Metaphysics 1010a |
293 | Being unafraid (perhaps through ignorance) and being brave are two different things [Plato] |
Full Idea: To be unafraid (like a small child who doesn't understand the danger) and to be brave are two quite different things. | |
From: Plato (Laches [c.381 BCE], 197b) |
