"Mr. Tugan repeats the old trick of the reactionaries: first to misinterpret socialism by making it out to be an absurdity, and then to triumphantly refute the absurdity! When we say that experience and reason prove that men are not equal, we mean by equality, equality in abilities or similarity in physical strength and mental ability.It goes without saying that in this respect men are not equal. No sensible person and no socialist forgets this. But this kind of equality has nothing whatever to do with socialism. If Mr. Tugan is quite unable to think, he is at least able to read; were he to take the well-known work of one of the founders of scientific socialism, Frederick Engels, directed against Dühring, he would find there a special section explaining the absurdity of imagining that economic equality means anything else than the abolition of classes. But when professors set out to refute socialism, one never knows what to wonder at most—their stupidity, their ignorance, or their unscrupulousness."
