We give advice, we do not inspire conduct.

There are some bad qualities which make great talents.

There is no better proof of a man's being truly good than his desiring to be constantly under the observation of good men.

Perfect behavior is born of complete indifference.

Constancy in love is a perpetual inconstancy which fixes our hearts successively to all the qualities of the person loved--sometimes admiring one and sometimes another above all the rest--so that this constancy roves as far as it can, and is no better than inconstancy, confined within the compass of one person.

Happy people rarely correct their faults; they consider themselves vindicated, since fortune endorses their evil ways.

The violence we do to ourselves in order to remain faithful to the one we love is hardly better than an act of infidelity.
