Newtonian physics and quantum mechanics are partners in a double irony. Newtonian physics is based upon the idea of laws which govern phenomena and the power inherent in understanding them, but it leads to impotence in the face of a Great Machine which is the universe. Quantum mechanics is based upon the idea of minimal knowledge of future phenomena (we are limited to knowing probabilities) but it leads to the possibility that our reality is what we choose to make it.(Don't worry much if this is not very clear to you... this one is explained over several pages in the book and it will be very clear if you are reading it in the book.)
In another place it quotes a book of Carl Jung on psychology, and the idea resembles what I saw in The Secret:
The psychological rule says that when an inner situation is not made conscious, it happens outside, as fate. That is to say, when the individual remains undivided and does not become conscious of his inner contradictions, the world must perforce act out the conflict and be torn into opposite halves.It's a very good read if you like science in general.
