5400 | In any possible world we feel that two and two would be four [Russell] |
Full Idea: In any possible world we feel that two and two would be four. | |
From: Bertrand Russell (Problems of Philosophy [1912], Ch. 7) | |
A reaction: Thinking of necessity in terms of possible worlds is not a new invention, but then Russell was a keen fan of Leibniz. Suppose there were no world at all, and only one truth, namely that two and two make five? (No, I can't make sense of that!) |
18872 | We should reject distinct but indiscernible worlds [Cameron] |
Full Idea: I think we should reject distinct but indiscernible worlds. | |
From: Ross P. Cameron (Truthmakers, Realism and Ontology [2008], 'Max and Nec') | |
A reaction: An interesting passing remark. Presumably there would be unknowable truths about such worlds, which wouldn't bother a full-blooded realist. Indiscernible to whom? Me? Humanity? A divine mind? |
