"The element of truth behind all this, which people are so ready to disavow, is that men are not gentle creatures who want to be loved, and who at the most can defend themselves if they are attacked; they are, on the contrary, creatures among whose instinctual endowments is to be reckoned a powerful share of aggressiveness. As a result, their neighbour is for them not only a potential helper or sexual object, but also someone who tempts them to satisfy their aggressiveness on him, to exploit his capacity for work without compensation, to use him sexually without his consent, to seize his possessions, to humiliate him, to cause him pain, to torture him and to kill him. Homo homini lupus."
"That the education of young people at the present day conceals from them the part which sexuality will play in their lives is not the only reproach which we are obliged to make against it. Its other sin is that it does not prepare them for the aggressiveness of which they are destined to become the objects. In sending the young out into life with such a false psychological orientation, education is behaving as though one were to equip people on a Polar expedition with summer clothing and maps of the Italian Lakes. In this it becomes evident that a certain misuse is being made of ethical demands. The strictness of those demands would not do so much harm if education were to say: 'This is how men ought to be, in order to be happy and to make others happy; but you have to reckon on their not being like that.' Instead of this the young are made to believe that everyone else fulfills those ethical demands -- that is, that everyone else is virtuous. It is on this that the demand is based that the young, too, shall become virtuous."
