Nature is an infinite sphere of which the center is everywhere and the circumference nowhere.

Two things control men's nature, instinct and experience.

Man's true nature being lost, everything becomes his nature as, his true good being lost, everything becomes his good.

Our nature consists in motion complete rest is death.

Habit is a second nature that destroys the first. But what is nature? Why is habit not natural? I am very much afraid that nature itself is only a first habit, just as habit is a second nature.
