All growth toward perfection is but a returning to original existence.

To the yoke of necessity every one willingly bows the head. Still, wherever an actually complicated aspect of things presents itself, it is more difficult to discover exactly what is necessary; but by the very acknowledgment of the principle, the problem invariably becomes simpler and the solution easier.
