I pointed out in the comments box that there is a further ingredient in Ockham's nominalism, namely the thesis that by ignorance of logic we are led astray into certain false and fantastical beliefs. This is not a million miles from Wittgenstein.
[Philosophical problems] are, of course, not empirical problems; they are solved, rather, by looking into the workings of our language, and that in such a way as to make us recognise those workings: in despite of an urge to misunderstand them. The problems are solved, not by giving new information, but by arranging what we have always known. Philosophy is a battle against the bewitchment of our intelligence by means of language.
