Evolution & ethics: T.H. Huxley's "Evolution and ethics" with new essays on its Victorian and sociobiological context

It strikes me that men who are accustomed to contemplate the active or passive extirpation of the weak, the unfortunate, and the superfluous; who justify that conduct on the ground that it has the sanction of the cosmic process, and is the only way of ensuring the progress of the race; who, if they are consistent, must rank medicine among the black arts and count the physician a mischievous preserver of the unfit; on whose matrimonial undertakings the principles of the stud have the chief influence; whose whole lives, therefore are an education in the noble art of suppressing natural affection and sympathy, are not likely to have any large stock of those commodities left.
