I viewed my fellow man not as a fallen angel, but as a risen ape.

Monks, nuns, long-term spinsters and bachelors and permanent homosexuals are all, in a reproductive sense, aberrant. Society has bred them, but they have failed to return the compliment.

There is nothing biologically unusual about a homosexual act of pseudocopulation. Many species indulge in this, under a variety of circumstances.

The response of teenagers to their idols is relevant. As an audience, they enjoy themselves, not by screaming with laughter, but screaming with screams.

Looking back now on the whole sexual scene we can see that our species has remained much more loyal to its basic biological urges than we might at first imagine. Its primate sexual system with carnivore modifications has survived all the fantastic technological advances remarkably well.

Aquatic animals suffer from the disadvantage that they cannot scream when in pain, so we find it hard to gauge the degree of their agony. If fish could scream, angling purely for sport would be outlawed without delay.

Biologically speaking, if something bites you it's more likely to be female.
