If you are not already familiar with Oxford’s series of Very Short Introductions, I recommend having a look. I’ve read about two dozen of them to this point and have found them to be consistently excellent.
I’ve just finished reading the volume on Quantum Theory, written by John Polkinghorne. I especially liked his concluding two paragraphs, where in the space of a few sentences he says all that is important in dealing with the woo-meisters who use the subject for their own New Agey ends:
It seems appropriate to close this chapter with an intellectual health warning. Quantum theory is certainly strange and surprising, but it is not so odd that according to it `anything goes.’ Of course, no one would actually argue with such crudity, but there is a kind of discourse that can come perilously close to adopting that caricature attitude. One might call it `quantum hype.’ I want to suggest that sobriety is in order when making an appeal to quantum insight.
We have seen that the EPR effect does not offer an explanation of telepathy, for its degree of mutual entanglement is not one that could facilitate the transfer of information. Quantum processes in the brain may possibly have some connection with the existence of the human conscious mind, but random subatomic uncertainty is very different indeed from the exercise of the free will of an agent. Wave/particle duality is a highly surprising and instructive phenomenon, whose seemingly paradoxical character has been resolved for us by the insights of quantum field theory. It does not, however, afford us a license to indulge in embracing any pair of apparently contradictory notions that take our fancy. Like a powerful drug, quantum theory is wonderful when applied correctly, disastrous when abused and misapplied.
