You never see animals going through the absurd and often horrible fooleries of magic and religion. . . . Dogs do not ritually urinate in the hope of persuading heaven to do the same and send down rain. Asses do not bray a liturgy to cloudless skies. Nor do cats attempt, by abstinence from cat's meat, to wheedle the feline spirits into benevolence. Only man behaves with such gratuitous folly. It is the price he has to pay for being intelligent but not, as yet, quite intelligent enough.

Man is so intelligent that he feels impelled to invent theories to account for what happens in the world. Unfortunately, he is not quite intelligent enough, in most cases, to find correct explanations. So that when he acts on his theories, he behaves very often like a lunatic.

Man is a clever animal who behaves like an imbecile.

Man only is endowed with wisdom so as to understand religion, and this is the principal if not the only difference betwixt him and dumb animals; for other things that seem peculiar to him, though they are not the same in them, yet they appear to be alike … What is there more peculiar to man than reason, and foresight? Yet there are animals which make several different ways of retiring from their dens; that when in danger they may escape; which without understanding and forethought they could not do. Others make provision for the future.

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.

They say that animals are incapable of feelings and reasoning. This is false. No living thing on earth is void of either. They also say that man is the most intelligent — and the most superior — species on earth. This is also false. It is very arrogant to assume that we are the most intelligent species when we keep repeating the same mistakes over and over again. It has been shown that both rats and monkeys learn from making errors, yet we have not. Our history proves this. All creatures on earth have the capacity to love and grieve the same way we do. No life on the planet is more deserving than another. Those who think so, are the true savages.

“Man is not a rational animal; he is a rationalizing animal.
“For explanations of a universe that confuses him he seizes onto numerology, astrology, hysterical religions, and other fancy ways to go crazy. Having accepted such glorified nonsense, facts make no impression on him, even if at the cost of his own life. Joe, one of the hardest things to believe is the abysmal depth of human stupidity.”

To animals not only human virtues but even human vices are forbidden: their whole constitution, mental and bodily, is unlike that of human beings...they possess intellect, the greatest attribute of all, but in a rough and inexact condition. It is, consequently, able to grasp those visions and semblances which rouse it to action, but only in a cloudy and indistinct fashion. Their impulses and outbreaks are violent, and that they do not feel fear, anxieties, grief, or anger, but some semblances of these feelings: wherefore they quickly drop them and adopt the converse of them: they graze after showing the most vehement rage and terror, and after frantic bellowing and plunging they straightaway sink into quiet sleep.

Animals only follow their natural instincts; but man, unless he has experienced the influence of learning and philosophy, is at the mercy of impulses that are worse than those of a wild beast. There is no beast more savage and dangerous than a human being who is swept along by the passions of ambition, greed, anger, envy, extravagance, and sensuality.

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.

It has been generally, but not always, the custom of naturalists to degrade the powers of dumb animals into mere instinct, and not to allow them reason; and on the other hand to elevate the qualities of man, by entirely disavowing the power of instinct in man, giving him the use of reason alone. It appears to me, that there is such a quality as instinct; by which I understand a desire to do any thing without knowing why, or without having the object in view which it is to reach. I am of opinion that both reason and instinct act in man and also in brutes; and I will even grant that the proportion of reason to instinct is greater in man than in other animals; but that the latter possess a great portion of reason would it seems be absurd to dispute.

Men are reasoning rather than reasonable animals.

The creature known as man is of course highly intelligent, he's capable of manufacturing almost anything from rumours to test-tube babies and yet he destroys two to three species every day. This is the absurdity of man.
