Miguel de Unamuno on Mortal ManTragic Sense of Life, trans. J.E. Crawford Flitch (Dover: 1954), orig. 1921, p. 1.
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.
