“I saw that the writers on vegetarianism had examined the question very minutely, attacking it in its religious, scientific, practical and medical aspects. Ethically they had arrived at the conclusion that man's supremacy over the lower animals meant not that the former should prey upon the latter, but that the higher should protect the lower, and that there should be mutual aid between the two as between man and man.”

“In the slow accretion of self-images that is the mortar between periods in the history of our civilization, a third character ideal emerged, in part from the failure of the previous two [political man and religious man]: economic man, one who would cultivate rationally his very own garden, meanwhile solacing himself with the assumption that by thus attending to his own lower needs a general satisfaction of the higher needs would occur. A moral revolution was the result: what had been lower in the established hierarchy of human interests was asserted to be higher.”

“As if to demonstrate, by a striking example, the impossibility of erecting any cerebral barrier between man and the apes, Nature has provided us, in the latter animals, with an almost complete series of gradations from brains little higher than that of a Rodent, to brains little lower than that of Man.”

“While there are two ways of contending, one by discussion, the other by force, the former belonging properly to man, the latter to beasts, recourse must be had to the latter if there be no opportunity for employing the former.”
Nam cum sint duo genera decertandi, unum per disceptationem, alterum per vim, cumque illud proprium sit hominis, hoc beluarum, confugiendum est ad posterius, si uti non licet superiore.

“I think that gay marriage is something that should be between a man and a woman.”

“A man who wants the truth becomes a scientist; a man who wants to give free play to his subjectivity may become a writer; but what should a man do who wants something in between?”

“Why should there be any more the old dividing line between man and his brother-man? why should the fires of prejudice flare up anew between us? why should we not maintain this common ground which we have found at last, and hedge it round, and protect it — the stronghold of freedom and of all the humanities for the long years to come?”

“Vegetarians should have that moral basis—that a man was not born a carnivorous animal, but born to live on the fruits and herbs that the earth grows.”

“One thing that is important is that, if you have a choice between a lower valuation with someone you really like, or higher valuation with someone you have a question mark about, take the lower valuation.”

“The higher man is distinguished from the lower by his fearlessness and his readiness to challenge misfortune.”
