Sincerity is an opening of the heart; we find it in very few persons; and that which we see ordinarily is only a cunning deceit to attract the confidence of others.

Weak people cannot be sincere.

People are more slanderous from vanity than from malice.

Men would not live in society long if they were not each others dupes.

It is never more difficult to speak well than when we are ashamed of keeping silent.

We talk little when vanity does not make us.

Tastes in young people are changed by natural impetuosity, and in the aged are preserved by habit.

The tranquility or agitation of our temper does not depend so much on the big things which happen to us in life, as on the pleasant or unpleasant arrangements of the little things which happen daily.

The happiness and unhappiness of men depend as much on their turn of mind as on fortune.

Sobriety is love of health, or inability to eat much.
