Carl Linnaeus on Man

“I demand of you, and of the whole world, that you show me a generic character—one that is according to generally accepted principles of classification, by which to distinguish between Man and Ape. I myself most assuredly know of none. ...But, if I had called man an ape, or vice versa, I should have fallen under the ban of all the ecclesiastics. It may be that as a naturalist I ought to have done so.”

“As a natural historian according to the principles of science, up to the present time I have been not been able to discover any character by which man can be distinguished from the ape; for there are somewhere apes which are less hairy than man, erect in position, going just like him on two feet, and recalling the human species by the use they make of their hands and feet, to such an extent, that the less educated travellers have given them out as a kind of man.”

“No one has any right to be angry with me, if I think fit to enumerate man among the quadrapeds. Man is neither a stone nor a plant, but an animal, for such is his way of living and moving; nor is he a worm, for then he would have only one foot; nor an insect, for then he would have antennae; nor a fish, for he has no fins; nor a bird, for he has no wings. Therefore, he is a quadraped, had a mouth like that of other quadrapeds, and finally four feet, on two of which he goes, and uses the other two for prehensive purposes.”
