"Bugger" (in French, _bougre_) is a corruption of "Bulgar," the ancient Bulgarian heretics having been popularly supposed to practise this perversion.

The people of every country have always been eager to associate sexual perversions with some other country than their own.
The terms usually adopted in the present volume are "sexual inversion" and "homosexuality." The first is used more especially to indicate that the sexual impulse is organically and innately turned toward individuals of the same sex.

The second is used more comprehensively of the general phenomena of sexual attraction between persons of the same sex, even if only of a slight and temporary character.

It may be admitted that there is no precise warrant for any distinction of this kind between the two terms.

The distinction in the phenomena is, however, still generally recognized; thus Iwan Bloch applies the term "homosexuality" to the congenital form, and "pseudo-homosexuality" to its spurious or simulated forms.
