"That there may be in inborn propensity toward sodomy doesn't signify anything: I have little doubt I have in inborn propensity toward sloth, wrath and pride, while others doubtless have inborn propensities toward avarice, gluttony, heterosexual fornication, envy, . . ."

Hell, I doubt every bit of that.

I'm no doctor, so what do I know?
I believe (just as every qualifier in the article believes), genes dictate physical properties.
The rest is the result of thought patterns ... taught and learned ... (because one believes a particular way or view is correct, one follows the paths that way or view directs.)

Oh, a tabula rasa type.

Sorry, too much research on biological basis for behavior suggests we do indeed have inborn propensities. Identical twins reared apart go into the same or similar lines of work far more often than do adoptive siblings raised together from birth. In case you hadn't notice, the brain is physical.

We all know that gross deformities of the brain (Downs syndrome, for example) have a genetic basis. Why are you fighting the obvious? Do you really buy the argument that inborn = morally right?
