“Thou shalt not commit adultry is a command which makes no distinction between the following persons. They are all required to obey it: children at birth. Children in the cradle. School children. Youths and maidens. Fresh adults. Older ones. Men and women of 40. Of 50. Of 60. Of 70. Of 80. Of 100. The command does not distribute its burden equally, and cannot. It is not hard upon the three sets of children.”

“Now there you have a sample of man’s “reasoning powers,” as he calls them. He observes certain facts. For instance, that in all his life he never sees the day that he can satisfy one woman; also, that no woman ever sees the day that she can’t overwork, and defeat, and put out of commission any ten masculine plants that can be put to bed to her. He puts those strikingly suggestive and luminous facts together, and from them draws this astonishing conclusion: The Creator intended the woman to be restricted to one man.”

“Now what I contend is that my body is my own, at least I have always so regarded it. If I do harm through my experimenting with it, it is I who suffer, not the state.”

“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.”
