There is nothing more difficult to take in hand, more perilous to conduct, or more uncertain in its success, than to take the lead in the introduction of a new order of things.
It is the free alone which never changes, and the unchangeable alone which is free; for change is produced by something exterior to a thing, or within itself, which is more powerful than the surroundings.
And if joy were not on the earth,
There were an end of change and birth,
And Earth and Heaven and Hell would die,
And in some gloomy barrow lie
Folded like a frozen fly.
