  Many commentators hold that consciousness of self is central to the Critical philosophy. There is reason to question this: unified consciousness is central, but consciousness of self? That is not so clear. Whatever, the topic is intrinsically interesting and Kant achieved some remarkable insights into it. Strangely, none of his immediate successors took them up after his death and they next appeared at the earliest in Wittgenstein (1934–5) and perhaps not until Shoemaker (1968). Kant never discussed consciousness of self in its own right, only in the context of pursuing other objectives, and his remarks on the topic are extremely scattered. When we pull his various remarks together, we can see that Kant advanced at least seven major theses about consciousness of and  knowledge of self.  We will consider them one-by-one.
