Context

“Shall we exclude the negroes like the Americans, or the Hindoos like some Englishmen, or the Jews like some others? If we include all men without exception, why should we not include also the higher animals, many of whom are superior to the lowest specimens of the human race. We know nothing of humanity as an eternal object, and we know nothing of its limits. Humanity is a fiction, and it is impossible to love it. It would, doubtless, be very advantageous if men could love humanity just as they love their family. It would be very advantageous, as Communists advocate, to replace the competitive, individualistic organization of men's activity by a social universal organization, so that each would be for all and all for each.” source
