“What is that? Is that Slender Man?”

Letter to Major-General John Sullivan (15 December 1779), published in The Writings of George Washington (1890) by Worthington Chauncey Ford, Vol. 8, p. 139
1770s
Context: A slender acquaintance with the world must convince every man, that actions, not words, are the true criterion of the attachment of his friends, and that the most liberal professions of good will are very far from being the surest marks of it. I should be happy that my own experience had afforded fewer examples of the little dependence to be placed upon them.

Context: For the recognition of private property has really harmed Individualism, and obscured it, by confusing a man with what he possesses. It has led Individualism entirely astray. It has made gain not growth its aim. So that man thought that the important thing was to have, and did not know that the important thing is to be. The true perfection of man lies, not in what man has, but in what man is. Private property has crushed true Individualism, and set up an Individualism that is false. It has debarred one part of the community from being individual by starving them. It has debarred the other part of the community from being individual by putting them on the wrong road and encumbering them.

Variant: Experience is not what happens to you; it's what you do with what happens to you.

Context: The poet is, etymologically, the maker. Like all makers, he requires a stock of raw materials — in his case, experience. Now experience is not a matter of having actually swum the Hellespont, or danced with the dervishes, or slept in a doss-house. It is a matter of sensibility and intuition, of seeing and hearing the significant things, of paying attention at the right moments, of understanding and co-ordinating. Experience is not what happens to a man; it is what a man does with what happens to him. It is a gift for dealing with the accidents of existence, not the accidents themselves. By a happy dispensation of nature, the poet generally possesses the gift of experience in conjunction with that of expression.

Context: Go — take the mother's soul, and learn three truths: Learn What dwells in man, What is not given to man, and What men live by. When thou hast learnt these things, thou shalt return to heaven.
