3 ideas
| 9138 | An infinite series of sentences asserting falsehood produces the paradox without self-reference [Yablo, by Sorensen] |
| Full Idea: Banning self-reference is too narrow to avoid the liar paradox. With 1) all the subsequent sentences are false, 2) all the subsequent sentences are false, 3) all the subsequent... the paradox still arises. Self-reference is a special case of this. | |
| From: report of Stephen Yablo (Paradox without Self-Reference [1993]) by Roy Sorensen - Vagueness and Contradiction 11.1 | |
| A reaction: [Idea 9137 pointed out that the ban was too narrow. Sorensen p.168 explains why this one is paradoxical] This is a nice example of progress in philosophy, since the Greeks would have been thrilled with this idea (unless they knew it, but it was lost). |
| 3583 | External objects are permanent possibilities of sensation [Mill] |
| Full Idea: External objects are permanent possibilities of sensation. | |
| From: John Stuart Mill (Examination of Sir Wm Hamilton's Philosophy [1865]), quoted by Michael Williams - Problems of Knowledge Ch.9 |
| 3537 | I judge others' feeling by analogy with my body and behaviour [Mill] |
| Full Idea: I conclude other humans have feelings like me because they have bodies like mine (which I know in my case to be antecedent to feelings), and because they exhibit acts and outwards signs which I know in my own case to be caused by feelings. | |
| From: John Stuart Mill (Examination of Sir Wm Hamilton's Philosophy [1865], p.243), quoted by Keith T. Maslin - Introduction to the Philosophy of Mind 8.2 | |
| A reaction: It is hard to see anything further that can be added to the 'other minds' question. Behaviour is highly relevant (imagine meeting a human who talked like a robot), but so are bodies (imagine a tin box that talked like Marilyn Monroe). |
