There are two main kinds of books about quantum mechanics. There are those in which we learn about abstract concepts such as Hilbert spaces, state vectors and density matrixes, but where the author never addresses-or only pays lip-service to-the question of what quantum mechanics actually means. This is the approach often taken in textbooks. The other, quite opposite, approach focuses on the interpretative question - drawing all kinds of conclusions and analogies, talking about telepathy and other mysteries, and perhaps even claiming that quantum mechanics transcends Western philosophy.
