Nothing is so insufferable to man as to be completely at rest, without passions, without business, without diversion, without study.

There will immediately arise from the depth of his heart weariness, gloom, sadness, fretfulness, vexation, despair.

It is dangerous to explain too clearly to man how like he is to the animals without pointing out his greatness. It is also dangerous to make too much of his greatness without his vileness.

Man must not be allowed to believe that he is equal either to animals or to angels, nor to be unaware of either, but he must know both.

We must keep our thought secret, and judge everything by it, while talking like the people.

Vanity is illustrated in the cause and effect of love, as in the case of Cleopatra.
