Homo sum; nihil humani a me alienum puto , said the Latin playwright. And I would rather say, Nullum hominem a me alienum puto : I am a man; no other man do I deem a stranger. For to me the adjective humanus is no less suspect than its abstract substantive humanitas , humanity. Neither "the human" nor "humanity," neither the simple adjective nor the substantivized adjective, but the concrete substantive-man. The man of flesh and bone; the man who is born, suffers, and dies-above all, who dies; the man who eats and drinks and plays and sleeps and thinks and wills; the man who is seen and heard; the brother, the real brother.

For there is another thing which is also called man, and he is the subject of not a few lucubrations, more or less scientific. He is the legendary featherless biped, the social contractor of Rousseau, the homo economicus of the Manchester school, the homo sapiens of Linnaeus, or, if you like, the vertical mammal. A man neither of here nor there, neither of this age nor of another, who has neither sex nor country, who is, in brief, merely an idea. That is to say, a no-man.

The man we have to do with is the man of flesh and bone-I, you, reader of mine, the other man yonder, all of us who walk solidly on the earth.
