Below you will find the text of the lecture "Expertise or Experience" by psychiatrist C. van der Kroef, which was delivered in 1983. In my opinion he says some important things about the use of psychiatric drugs and their harmful effects, the dubious role played by the manufactures of these drugs, and also about patients' own expertise and the right which in his opinion they should have to be heard regarding their worries and the effects and side-effects of the psychiatric drugs which are administered to them. Although this lecture is from 1983, I have included it here because I believe it to still be quite contemporary. You will find the lecture here.
Very recommendable too is the site of The Association for Medical and Therapeutic Self-determination (based in the Netherlands). Http://www.metzelf.nl/
