It's called "Human Nature: The Categorical Framework" by P.M.S. Hacker. The chapter of direct interest to you is called "The Mind". https://www.amazon.com/Human-Nature-Categorial-Framework-Hac...
Hacker is a philosopher of language and of mind, and he is a very clear writer. He works in a similar method to Wittgenstein and is a scathing critic of the tendency for many (particularly in cognitive neuroscience) to remain in a Cartesian dualist mindset that is, really, 17th-century metaphysics and nonsense. His point on 'the mind' is that it is not an entity. That doesn't mean it is nothing, but that means it is not something. It is a faculty, a conceptual shorthand for our rational powers, or, as Aristotle describes the "psuchē", "the actuality of a body that has life". We alone as persons can do the things that can be attributed to a rational mind.
Reading him is like spring cleaning your mind of nonsense.
(He also has some hilarious criticisms of Chomsky and his treatment of language in the book, and its sequel.)
