Scientists are supposed to live in ivory towers. Their darkrooms and their vibration-proof benches are supposed to isolate their activities from the disturbances of common life. What they tell us is supposed to be for the ages, not for the next election. But the reality may be otherwise.

One reason why I recommend the abandonment of religious beliefs is because I think those beliefs are wrong. There is no evidence that our world was created by divine intention, that a god intercedes in human affairs, or that there is life after death. Religion is a hangover from humankind's timorous infancy; it's time for us to walk upright and unafraid, and to take charge of our own lives.

Although homosexual behavior is very common in the animal world, it seems to be very uncommon that individual animals have a long-lasting predisposition to engage in such behavior to the exclusion of heterosexual activities. Thus, a homosexual orientation, if one can speak of such thing in animals, seems to be a rarity.

It's important to stress what I didn't find. I did not prove that homosexuality is genetic, or find a genetic cause for being gay. I didn't show that gay men are born that way, the most common mistake people make in interpreting my work. Nor did I locate a gay center in the brain.

I felt if I didn't find anything, I would give up a scientific career altogether.
