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.

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

Man is many things, but he is not rational.

— A man for whom accident discovers sense, is not a rational being. A man only is so who understands, who distinguishes, who tests it.

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 is a rational animal. So at least we have been told. Throughout a long life I have searched diligently for evidence in favor of this statement. So far, I have not had the good fortune to come across it.

Pues el hombre es un animal no sólo vil y despreciable, sino también (y no lo diría si la experiencia no me lo hubiera mostrado, y siguiera mostrando, tan claramente) perjudicial, variable, desleal, poco confiable, feroz y cruel.

the current situation being a toss-up as to what you want to believe. Man is not a rational animal, he is a rationalizing animal. Hence you will find that often what you believe is what you want to believe, rather than being the result of careful thinking.

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

Men are reasoning rather than reasonable animals.

My definition of man is a cooking animal. The beasts have memory, judgement, and the faculties and passions of our minds in a certain degree; but no beast is a cook.

Men are rather reasoning than reasonable animals, for the most part governed by the impulse of passion.

Man is an unoriginal animal. Unoriginal within the law in his daily respectable life, equally unoriginal outside the law. If a man commits a crime, any other crime he commits will resemble it closely.

The proper definition of a man is an animal that writes letters.
