Was Sir Isaac Newton gay?

But of course, if ever a man were, Sir Isaac Newton was gay. No gay man reading any of the many fine biographies of Newton has the least doubt that he was.  Straight ("normally heterosexual") people are not so sure. Why is that?  Well, in the first place, straight people--and, until very recently, most gay people (including Newton)--have not understood, and mostly still do not understand, that sexual preference/orientation is not a choice that anyone, gay or straight, deliberately makes; so straight people don't understand that being gay, typically, has driven gay men like Newton, who are scrupulous examiners of their own minds and consciences, mad, to think that they must somehow, have chosen to be gay (although they do not, and never can, remember just how or when that choice was made)--in the very way that we know Sir Isaac to have been demented, at various times throughout his life: with  depression, fulminating rages, hysteria, and "mental break-downs." Because--intelligent man that he was--still, as much as any man, Newton shared the Popular Wisdom, or Received Unwisdom, of his day, and could not bring himself to doubt (or let it be known that he doubted; which comes to the same thing) such preposterous absurdities as the Protestant Christianity, Faculty Psychology, or the half-instinctual, unexamined, moralistic Natural Philosophy which then prevailed as unquestioned, self-evident, sempiternal Truth. And still, of course, does.
