Man is a thinking animal, a talking animal, a toolmaking animal, a building animal, a political animal, a fantasizing animal. But, in the twilight of a civilization he is chiefly a taxpaying animal.

Hugh MacLennan

Man is a rational animal—so at least I have been told. … Aristotle, so far as I know, was the first man to proclaim explicitly that man is a rational animal. His reason for this view was … that some people can do sums. … It is in virtue of the intellect that man is a rational animal. The intellect is shown in various ways, but most emphatically by mastery of arithmetic. The Greek system of numerals was very bad, so that the multiplication table was quite difficult, and complicated calculations could only be made by very clever people.

Bertrand Russell

I fear animals regard man as a creature of their own kind which has in a highly dangerous fashion lost its healthy animal reason - as the mad animal, as the laughing animal, as the weeping animal, as the unhappy animal.

Friedrich Nietzsche

The importance of insomnia is so colossal that I am tempted to define man as the animal who cannot sleep. Why call him a rational animal when other animals are equally reasonable? But there is not another animal in the entire creation that wants to sleep yet cannot.

Emile M. Cioran

When a man confines an animal in a cage, he assumes ownership of that animal. But an animal is an individual; it cannot be owned. When a man tries to own an individual, whether that individual be another man, an animal or even a tree, he suffers the psychic consequences of an unnatural act.

Tom Robbins

He said that man’s heart was the only bad heart in the animal kingdom; that man was the only animal capable of feeling malice, envy, vindictiveness, revengefulness, hatred, selfishness, the only animal that loves drunkenness, almost the only animal that could endure personal uncleanliness and a filthy habitation, the sole animal in whom was fully developed the base instinct called patriotism, the sole animal that robs, persecutes, oppresses and kills members of his own tribe, the sole animal that steals and enslaves the members of any tribe.

Mark Twain

I wonder who it was defined man as a rational animal. It was the most premature definition ever given. Man is many things, but he is not rational.

Oscar Wilde

Man is always something worse or something better than an animal; and a mere argument from animal perfection never touches him at all. Thus, in sex no animal is either chivalrous or obscene. And thus no animal invented anything so bad as drunkeness - or so good as drink.

Gilbert K. Chesterton

Animal liberationists do not separate out the human animal, so there is no rational basis for saying that a human being has special rights. A rat is a pig is a dog is a boy. They're all mammals.

Ingrid Newkirk

Not only are the philosophies of animal rights and animal welfare separated by irreconcilable differences... the enactment of animal welfare measures actually impedes the achievement of animal rights... Welfare reforms, by their very nature, can only serve to retard the pace at which animal rights goals are achieved.

Gary L. Francione

During its development the animal passes through all stages of the animal kingdom. The foetus is a representation of all animal classes in time.

Lorenz Oken

If you turn your back on these people, you yourself are an animal. You may be a well-dressed animal, but you are nevertheless an animal.

Ed Koch

Instinct guides the animal better than the man. In the animal it is pure, in man it is led astray by his reason and intelligence.

Denis Diderot

The Seven Commandments: Whatever goes upon two legs is an enemy. Whatever goes upon four legs, or has wings, is a friend. No animal shall wear clothes. No animal shall sleep in a bed. No animal shall drink alcohol. No animal shall kill any other animal. All animals are equal.
