Injustice, poverty, slavery, ignorance - these may be cured by reform or revolution. But men do not live only by fighting evils. They live by positive goals, individual and collective, a vast variety of them, seldom predictable, at times incompatible.

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

When a man speaks of the need for realism one may be sure that this is always the prelude to some bloody deed.

Both liberty and equality are among the primary goals pursued by human beings throughout many centuries; but total liberty for wolves is death to the lambs, total liberty of the powerful, the gifted, is not compatible with the rights to a decent existence of the weak and the less gifted.

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.

Liberty for wolves is death to the lambs.

Philosophers are adults who persist in asking childish questions.
