| 5364 | It is hard not to believe that speaking humans are expressing thoughts, just as we do ourselves [Russell] |
| Full Idea: When human beings speak, it is very difficult to suppose that what we hear is not the expression of a thought, as we know it would be if we emitted the same sounds. | |
| From: Bertrand Russell (Problems of Philosophy [1912], Ch. 2) | |
| A reaction: This is partly the 'argument from analogy', which seems a bit suspect (induction from a single instance), but it is also the rather undeniable Humean idea that we have a 'natural belief' in other minds, which we could never disbelieve. |
| 5379 | If we didn't know our own minds by introspection, we couldn't know that other people have minds [Russell] |
| Full Idea: But for our acquaintance with the contents of our own minds, we should be unable to imagine the minds of others, and therefore we could never arrive at the knowledge that they have minds. | |
| From: Bertrand Russell (Problems of Philosophy [1912], Ch. 5) | |
| A reaction: Not only does this depend on the notorious 'argument from analogy', but it actually strikes me as false. If a robot observed a human to be writhing in pain, it would be mystified, until it inferred that we have minds in which we actually 'feel' damage. |
| 5410 | I learn the universal 'resemblance' by seeing two shades of green, and their contrast with red [Russell] |
| Full Idea: If I see simultaneously two shades of green, I can see that they resemble each other, and I see that they resemble each other more than they resemble a shade of red; in this way I become acquainted with the universal 'resemblance'. | |
| From: Bertrand Russell (Problems of Philosophy [1912], Ch.10) | |
| A reaction: This is strikingly different from the account of Hume, who seemed to regard resemblance as a fairly mechanical, computer-like activity of the brain, whereas Russell (an empiricist) responds by inclining towards Platonism. Hume sounds better here. |
