Wittgenstein argues that when philosophers ask what is time or what is number they are making linguistic mistakes, not philosophical ones, turning nonexistence into an object of inquiry via the bewitchment of philosophy. Philosophical Grammar spends more time on logic and mathematics, and their connections with signs, systems, and propositions, than any other book in the oeuvre of Wittgenstein's philosophical mission. That's Part II. Part I consists of those headfirst Wittgensteinian meditations, like what distinguishes signs from random marks or noises, and whether we have or need a general sense of language or statements at all. 
  
"Thought strikes us as mysterious. But not while we think. And we don't mean that it's psychologically remarkable. It isn't only that we see it as an extraordinary way of producing pictures and signs, we actually feel as if by means of it we had caught reality in our net."
