"Be not the slave of your own past - plunge into the sublime seas, dive deep, and swim far, so you shall come back with new self-respect, with new power, and with an advanced experience that shall explain and overlook the old."
Ralph Waldo Emerson (1803 - 1882)

Beware when the great God lets loose a thinker on this planet. Then all things are at risk. It is as when a conflagration has broken out in a great city, and no man knows what is safe, or where it will end. There is not a piece of science, but its flank may be turned to-morrow; there is not any literary reputation, not the so-called eternal names of fame, that may not be revised and condemned. The very hopes of man, the thoughts of his heart, the religion of nations, the manners and morals of mankind, are all at the mercy of a new generalization. Generalization is always a new influx of the divinity into the mind. Hence the thrill that attends it.
There is a principle which is the basis of things, which all speech aims to say, and all action to evolve, a simple, quiet, undescribed, undescribable presence, dwelling very peacefully in us, our rightful lord: we are not to do, but to let do; not to work, but to be worked upon.
"Finish each day and be done with it. You have done what you could. Some blunders and absurdities no doubt crept in; forget them as soon as you can. Tomorrow is a new day; begin it well and serenely and with too high a spirit to be cumbered with your old nonsense."
