Stanley Milgram

It is not so much the kind of person a man is as the kind of situation in which he finds himself that determines how he will act.

Ordinary people, simply doing their jobs, and without any particular hostility on their part, can become agents in a terrible destructive process. Moreover, even when the destructive effects of their work become patently clear, and they are asked to carry out actions incompatible with fundamental standards of morality, relatively few people have the resources needed to resist authority.

The disappearance of a sense of responsibility is the most far-reaching consequence of submission to authority.

Each individual possesses a conscience which to a greater or lesser degree serves to restrain the unimpeded flow of impulses destructive to others. But when he merges his person into an organizational structure, a new creature replaces autonomous man, unhindered by the limitations of individual morality, freed of humane inhibition, mindful only of the sanctions of authority.

But the culture has failed, almost entirely, in inculcating internal controls on actions that have their origin in authority. For this reason, the latter constitutes a far greater danger to human survival.

Control the manner in which a man interprets his world, and you have gone a long way toward controlling his behavior. That is why ideology, an attempt to interpret the condition of man, is always a prominent feature of revolutions, wars, and other circumstances in which individuals are called upon to perform extraordinary action.
