“Man is the Reasoning Animal. Such is the claim. I think it is open to dispute. Indeed, my experiments have proven to me that he is the Unreasoning Animal... In truth, man is incurably foolish. Simple things which other animals easily learn, he is incapable of learning. Among my experiments was this. In an hour I taught a cat and a dog to be friends. I put them in a cage. In another hour I taught them to be friends with a rabbit. In the course of two days I was able to add a fox, a goose, a squirrel and some doves. Finally a monkey. They lived together in peace; even affectionately.

Next, in another cage I confined an Irish Catholic from Tipperary, and as soon as he seemed tame I added a Scotch Presbyterian from Aberdeen. Next a Turk from Constantinople; a Greek Christian from Crete; an Armenian; a Methodist from the wilds of Arkansas; a Buddhist from China; a Brahman from Benares. Finally, a Salvation Army Colonel from Wapping. Then I stayed away for two whole days. When I came back to note results, the cage of Higher Animals was all right, but in the other there was but a chaos of gory odds and ends of turbans and fezzes and plaids and bones and flesh--not a specimen left alive. These Reasoning Animals had disagreed on a theological detail and carried the matter to a Higher Court.”

“I think I could turn and live with animals, they are so placid and self-contain’d, I stand and look at them long and long.

They do not sweat and whine about their condition, They do not lie awake in the dark and weep for their sins, They do not make me sick discussing their duty to God, Not one is dissatisfied, not one is demented with the mania of owning things, Not one kneels to another, nor to his kind that lived thousands of years ago, Not one is respectable or unhappy over the whole earth.”

“Beware that, when fighting monsters, you yourself do not become a monster... for when you gaze long into the abyss. The abyss gazes also into you.”
