Three hundred years after the Enlightenment, the idea of a science of human nature is still new to some people. But in those days, it was practically all anybody ever talked about. If there were underlying laws that explained physical phenomena, what laws explained human behavior? Time after time, attempts to agree on the foundations of such a science have collapsed under heated debates about terminology, or this camp’s refusal to accept that camp’s discoveries, or — homophobia.
When Paul said that psychology’s biggest hurdle was homophobia, he didn’t mean that scientists didn’t like gay people. He meant that they were unable to fully investigate their own psyches for fear of the homosexuality they might find. For a science of man (the species) must start with the scientist’s examination of himself before he can ever be objective about other people.
