Civilized society is perpetually menaced with disintegration through this primary hostility of men towards one another. - Sigmund Freud

The commandment, 'Love thy neighbour as thyself', is the strongest defence against human aggressiveness and an excellent example of the unpsychological [expectations] of the cultural super-ego. The commandment is impossible to fulfil; such an enormous inflation of love can only lower its value, not get rid of the difficulty. Civilization pays no attention to all this; it merely admonishes us that the harder it is to obey the precept the more meritorious it is to do so. But anyone who follows such a precept in present-day civilization only puts himself at a disadvantage vis-a-vis the person who disregards it. What a potent obstacle to civilization aggressiveness must be, if the defence against it can cause as much unhappiness as aggressiveness itself! 'Natural' ethics, as it is called, has nothing to offer here except the narcissistic satisfaction of being able to think oneself better than others. At this point the ethics based on religion introduces its promises of a better after-life. But so long as virtue is not rewarded here on earth, ethics will, I fancy, preach in vain. I too think it quite certain that a real change in the relations of human beings to possessions would be of more help in this direction than any ethical commands; but the recognition of this fact among socialists has been obscured and made useless for practical purposes by a fresh idealistic misconception of human nature.

The ego is always alert to the dangers that the unconscious may over-throw it. It may try to intellectualize away unconscious urges, inhibit them, project them onto others, or deny them.

The poor ego has a still harder time of it; it has to serve three harsh masters, and it has to do its best to reconcile the claims and demands of all three... The three tyrants are the external world, the superego, and the id.
