God makes nothing without order, and everything that forms itself develops imperceptibly out of small parts.

Nothing is accomplished all at once, and it is one of my great maxims, and one of the most completely verified, that Nature makes no leaps: a maxim which I have called the law of continuity.

There never is absolute birth nor complete death, in the strict sense, consisting in the separation of the soul from the body. What we call births are developments and growths, while what we call deaths are envelopments and diminutions.

He who hasn't tasted bitter things hasn't earned sweet things.

Every substance is as a world apart, independent of everything else except God.
