Man is a rational animal – so at least I have been told. Throughout a long life, I have looked diligently for evidence in favor of this statement, but so far I have not had the good fortune to come across it, though I have searched in many countries spread over three continents.

Man is a rational animal, and if human affairs are hard to regulate, his twofold nature is usually the cause. Reason is something ultimate; it would be the same in another planet, or in another universe, as it is here. Animal nature is something contingent; it might have been different. Our life is a compromise, a blend between the animal and the rational.

It has been said that man is a rational animal. All my life I have been searching for evidence which could support this.

Man is said to be a reasoning animal. I do not know why he has not been defined as an affective or feeling animal. Perhaps that which differentiates him from other animals is feeling rather than reason. More often I have seen a cat reason than laugh or weep. Perhaps it weeps or laughs inwardly — but then perhaps, also inwardly, the crab resolves equations of the second degree.

Man is the Reasoning Animal. Such is the claim. I think it is open to dispute.

Man is not a rational animal; he is a rationalizing animal.

Men are not rational beings, as commonly supposed. A man is a bundle of instincts, feelings, sentiments, which severally seek their gratification, and those which are in power get hold of reason and use it to their own ends, and exclude all other sentiments and feelings from power.

Man has been called the reasoning animal but he could with greater truthfulness be called the creature of suggestion. He is reasonable, but he is to a greater extent suggestible.

Man is a thinking being. His reason enables him to recognize his own potentialities and those of his world. He is thus not at the mercy of the facts that surround him, but is capable of subjecting them to a higher standard, that of reason. P. 6

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, the rational animal, can put up with anything except what seems to him irrational; whatever is rational is tolerable.

A man is rational in proportion as his intelligence informs and controls his desires.

Man is a rationalizing beast, if not a rational one.
