The mind, like all other things, will become impaired, the sciences are its food,--they nourish, but at the same time they consume it.

Love and friendship exclude each other.

Piety with some people, but especially with women, is either a passion, or an infirmity of age, or a fashion which must be followed.

An inconstant woman is one who is no longer in love; a false woman is one who is already in love with another person; a fickle woman is she who neither knows whom she loves nor whether she loves or not; and the indifferent woman, one who does not love at all.

At the beginning and at the end of love, the two lovers are embarrassed to find themselves alone.

A man may have intelligence enough to excel in a particular thing and lecture on it, and yet not have sense enough to know he ought to be silent on some other subject of which he has but a slight knowledge; if such an illustrious man ventures beyond the bounds of his capacity, he loses his way and talks like a fool.

Let us not complain against men because otheir rudeness, their ingratitude, their injustice, their arrogance, their love oself, their forgetfulness oothers. They are so made. Such is their nature.
