10931 | We can't say 'necessarily if x is in water then x dissolves' if we can't quantify modally [Quine] |
Full Idea: To say an object is soluble in water is to say that it would dissolve if it were in water,..which implies that 'necessarily if x is in water then x dissolves'. Yet we do not know if there is a suitable sense of 'necessarily' into which we can so quantify. | |
From: Willard Quine (Reference and Modality [1953], §4) | |
A reaction: This is why there has been a huge revival of scientific essentialism - because Krike seems to offer exacty the account which Quine said was missing. So can you have modal logic without rigid designation? |
