"This book is must for anyone who cares about social inequality, matters of mind, and the future. It, very comprehensively, juxtaposes scientific and social theories and practices with particular application to matters of gender, ethnicity, and sexual orientation. We learn of the different scientific theories and positions that scientists have taken in the past and present, and their translation into social practice. With a good deal of authority and erudition: the authors have managed to steer the readers easily through the minefields of ideology in a very readable and easy manner in order to clarify the argument that much of what we know about gender and sexual orientation has been in the service of prevailing ideologies."--Jacket.
