“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.”

“Man is a Religious Animal. He is the only Religious Animal. He is the only animal that has the True Religion--several of them. He is the only animal that loves his neighbor as himself and cuts his throat if his theology isn't straight. He has made a graveyard of the globe in trying his honest best to smooth his brother's path to happiness and heaven....The higher animals have no religion. And we are told that they are going to be left out in the Hereafter. I wonder why? It seems questionable taste.”

“I have been studying the traits and dispositions of the "lower animals" (so called) and contrasting them with the traits and dispositions of man. I find the result humiliating to me.”

“I believe our Heavenly Father invented man because he was disappointed in the monkey. I believe that whenever a human being, of even the highest intelligence and culture, delivers an opinion upon a matter apart from his particular and especial line of interest, training and experience, it will always be an opinion of so foolish and so valueless a sort that it can be depended upon to suggest our Heavenly Father that the human being is another disappointment and that he is no considerable improvement upon the monkey.”

“We had a little slave boy whom we had hired from some one, there in Hannibal. He was from the Eastern Shore of Maryland, and had been brought away from his family and his friends, half way across the American continent, and sold. He was a cheery spirit, innocent and gentle, and the noisiest creature that ever was, perhaps. All day long he was singing, whistling, yelling, whooping, laughing - it was maddening, devastating, unendurable. At last, one day, I lost all my temper, and went raging to my mother, and said Sandy had been singing for an hour without a single break, and I couldn't stand it, and wouldn't she please shut him up.The tears came into her eyes, and her lip trembled, and she said something like this - 'Poor thing, when he sings, it shows that he is not remembering, and that comforts me; but when he is still, I am afraid he is thinking, and I cannot bear it. He will never see his mother again; if he can sing, I must not hinder it, but be thankful for it. If you were older, you would understand me; then that friendless child's noise would make you glad.' It was a simple speech, and made up of small words, but it went home, and Sandy's noise was not a trouble to me any more.”

“I'd always thought I would feel like an animal released from its cage when my student days were finished, I felt more like a bird that had been pushed from its nest and told it must fly.”

“Mother, recently I have discovered the one way in which human beings differ completely from other animals. Man has, I know, language, knowledge, principles, and social order, but don't all the other animals have them too, granted the difference of degree? Perhaps the animals even have religions. Man boasts of being the lord of all creation, but it would seem as if essentially he does not differ in the least from other animals. But, Mother, there was one way I thought of. Perhaps you won't understand. It's a faculty absolutely unique to man - having secrets. Can you see what I mean?”
