Jealousy is bred in doubts. When those doubts change into certainties, then the passion either ceases or turns absolute madness.

Taste may change, but inclination never.

Heat of blood makes young people change their inclinations often, and habit makes old ones keep to theirs a great while.

Perfect courage is to do without witnesses what one would be capable of doing with the world looking on.

On neither the sun, nor death, can a man look fixedly.
