 The point here is an important one in the context of the condition question. Earlier we said that the condition question was perfectly legitimate because it is legitimate to ask what the condition of being physical is that, according to physicalism, everything has. But this legitimate question should not be interpreted as the demand for a reductive analysis of the notion of the physical. Consider Thales again: it is right to ask Thales what he means by ‘water’ — and in so doing demand an understanding of the notion of water — but it is wrong to demand of him a conceptual analysis of water.
