We should despair of the human race if these maxims had been made before 1830; but they set forth in so clear a manner the agreements and difficulties which distinguish you, your wife and a lover; they so brilliantly describe what your policy should be, and demonstrate to you so accurately the strength of the enemy, that the teacher has put his amour-propre aside, and if by chance you find here a single new thought, send it to the devil, who suggested this work.

LXV.
To speak of love is to make love.

LXVI.
In a lover the coarsest desire always shows itself as a burst of
honest admiration.

LXVII.
A lover has all the good points and all the bad points which are
lacking in a husband.

LXVIII.
A lover not only gives life to everything, he makes one forget life;
the husband does not give life to anything.

LXIX. All the affected airs of sensibility which a woman puts on invariably deceive a lover; and on occasions when a husband shrugs his shoulders, a lover is in ecstasies.

LXX.
A lover betrays by his manner alone the degree of intimacy in which he
stands to a married woman.

LXXI. A woman does not always know why she is in love. It is rarely that a man falls in love without some selfish purpose. A husband should discover this secret motive of egotism, for it will be to him the lever of Archimedes.

LXXII.
A clever husband never betrays his supposition that his wife has a
lover.

LXXIII. The lover submits to all the caprices of a woman; and as a man is never vile while he lies in the arms of his mistress, he will take the means to please her that a husband would recoil from.
