Liberty and equality, spontaneity and security, happiness and knowledge, mercy and justice - all these are ultimate human values, sought for themselves alone; yet when they are incompatible, they cannot all be attained, choices must be made, sometimes tragic losses accepted in the pursuit of some preferred ultimate end.

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.

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.

Life may be seen through many windows, none of them necessarily clear or opaque, less or more distorting than any of the others.

There is no a prior reason for supposing that the truth, when it is discovered, will necessarily prove interesting.

Liberty for wolves is death to the lambs.

The intellectual power, honesty, lucidity, courage, and disinterested love of the truth of the most gifted thinkers of the eighteenth century remain to this day without parallel. Their age is one of the best and most hopeful episodes in the life of mankind.
