As soon as an opinion becomes common it is sufficient reason for men to abandon it and to uphold the opposite opinion until that in its turn grows old, and they require to distinguish themselves by other things.

It is a great sign of mediocrity to praise always moderately.

Every thought is new when an author expresses it in a manner peculiar to himself.
