23025 | Philosophers should be more inductive, and test results by their conclusions, not their self-evidence [Russell] |
Full Idea: The progress of philosophy seems to demand that, like science, it should learn to practise induction, to test its premisses by the conclusions to which they lead, and not merely by their apparent self-evidence. | |
From: Bertrand Russell (Explanations in reply to Mr Bradley [1899], nr end) | |
A reaction: [from Twitter] Love this. It is 'one person's modus ponens is another person's modus tollens'. I think all philosophical conclusions, without exception, should be reached by evaluating the final result fully, and not just following a line of argument. |
16634 | I can't be unaware of anything which is in me [Descartes] |
Full Idea: Nothing can be in me of which I am entirely unaware. | |
From: René Descartes (Reply to First Objections [1641]), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 08.4 | |
A reaction: This I take to be a place where Descartes is utterly and catastrophically wrong. Until you grasp the utter falseness of this thought, the possibility of you (dear reader) understanding human beings is zero. Here 'I' obviously means his mind. |
468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice. | |
From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where? |
3635 | Essence must be known before we discuss existence [Descartes] |
Full Idea: According to the laws of true logic, we must never ask about the existence of anything until we first understand its essence. | |
From: René Descartes (Reply to First Objections [1641], 108) |
3634 | We can't prove a first cause from our inability to grasp infinity [Descartes] |
Full Idea: My inability to grasp an infinite chain of successive causes without a first cause does not entail that there must be a first cause, just as my inability to grasp infinite divisibility of finite things does not make that impossible. | |
From: René Descartes (Reply to First Objections [1641], 106) |
