The mob that hails the man on horseback, the Caesars and conquering heroes, does not retain its freedoms for long.

Good breeding consists in concealing how much we think of ourselves and how little we think of the other person.

Psychologism is, I believe, correct only in so far as it insists upon what may be called 'methodological individualism' as opposed to 'methodological collectivism'; it rightly insists that the 'behaviour' and the 'actions' of collectives, such as states or social groups, must be reduced to the behaviour and to the actions of human individuals. But the belief that the choice of such an individualist method implies the choice of a psychological method is mistaken.
