7550 | We could probably, in principle, infer minds from brains, and brains from minds [Russell] |
Full Idea: It seems not improbable that if we had sufficient knowledge we could infer the state of a man's mind from the state of his brain, or the state of his brain from the state of his mind. | |
From: Bertrand Russell (The Ultimate Constituents of Matter [1915], p.131) | |
A reaction: This strikes me as being a very good summary of the claim that mind is reducible to brain, which is the essence of physicalism. Had he been born a little later, Russell would have taken a harder line with physicalism. |
