"Does philosophy not result in conceptual truths – and is that not a cognitive achievement? That would be misleading … these conceptual truths are not statements of fact. They are descriptions of normative connections within the web of concepts that constitute our form of representation. They are said to be true. Indeed, they are often said to be necessary truths. That, of course, is correct –- but misleading. Their truth is akin to that of the proposition that the king in chess moves one square at a time. What we realize when a philosophical insight dawns on us is a feature of our form of representation. We attain an understanding of the way in which our familiar modes of description of things hang together."
