Conformities are called for much more eagerly today than yesterday... skeptics, liberals, individuals with a taste for private life and their own inner standards of behavior, are objects of fear and derision and targets of persecution for either side... in the great ideological wars of our time.

The case against the notion of historical objectivity is like the case against international law, or international morality; that it does not exist.

When one is engaged in a desperate defense of one's world and its values, nothing can be given away, any breach in the walls might be fatal, every point must be defended to the death.

If, as I believe, the ends of men are many, and not all of them are in principle compatible with each other, then the possibility of conflict - and of tragedy - can never wholly be eliminated from human life, either personal or social. The necessity of choosing between absolute claims is then an inescapable characteristic of the human condition. This gives its value to freedom as Acton conceived of it - as an end in itself, and not as a temporary need, arising out of our confused notions and irrational and disordered lives, a predicament which a panacea could one day put right.

The first people totalitarians destroy or silence are men of ideas and free minds.

One belief, more than any other, is responsible for the slaughter of individuals on the alter of the great historical ideas - justice or progress or happiness of future generations... or emancipation of a nation or race or class... this is the belief that somewhere... there is a final solution.

We are doomed to choose and every choice may entail irreparable loss.
