My desire for knowledge is intermittent; but my desire to commune with the spirit of the universe, to be intoxicated with the fumes, call it, of that divine nectar, to bear my head through atmospheres and over heights unknown to my feet, is perennial and constant.
Henry David ThoreauWhen one man has reduced a fact of the imagination to be a fact to his understanding, I foresee that all men will at length establish their lives on that basis.
Henry David Thoreau
