Our own distrust gives a fair pretence for the knavery of other people.

If there be a love pure and free from the admixture of our other passions, it is that which lies hidden in the bottom of our heart, and which we know not ourselves.

Men's happiness and misery depends altogether as much upon their own humor as it does upon fortune.

Happiness does not consist in things themselves but in the relish we have of them; and a man has attained it when he enjoys what he loves and desires himself, and not what other people think lovely and desirable.

Love, like fire, cannot subsist without constant impulse; it ceases to live from the moment it ceases to hope or to fear.
