ABSTRACT
The materialist doctrine that men are products of circumstances and upbringing, and that, therefore, changed men are products of other circumstances and changed upbringing, forgets, that it is men that change circumstances and that the educator himself needs educating. Hence, this doctrine necessarily arrives at dividing society into two parts, of which one is superior to society… . The coincidence of the changing of circumstances and of human activity can be conceived and rationally understood only as revolutionising practice.
