Abstract
The thesis of Delius's book is that statements of self-awareness such as "I am aware that I see a cat" possess what he calls 'Cartesian characteristics' of indubitability or absolute self-evidence. He argues that this is the case in virtue of the fact that such statements are not about anything independent of themselves. The book is described as a 'semantical inquiry', but it is not by any means a contribution to the philosophy of language of the predictable sort. Statements of self-awareness express what Delius calls 'egological experiences', and the subject of the book is most accurately described as consisting in the relations between egological statements and egological experiences, in a sense made clear in the course of the book.
