"There's no other place where we so quickly divide humans into two categories as sex. When I started doing research on the biology of sex development, one of the things that I realized is that the process is controlled by a series of enzymes and the reaction may be more or less complete. It's not just two poles where that whole process can end up. In between what we call the ideal biological male or ideal biological female, there's a whole range of other possibilities that don't differ from our basic preconceptions to the extent that we have names for them or call them a disorder. Just like with every other human trait, there are an infinite number of possibilities." -- Gerald N. Callahan, author of Between XX and XY, interviewed by Thomas Rogers in Salon (published 2009-07-07)
