Whether he sleeps or wakes,--whether he runs or walks,--whether he uses a microscope or a telescope, or his naked eye,--a man never discovers anything, never overtakes anything, or leaves anything behind, but himself. Whatever he says or does, he merely reports himself. If he is in love, he loves; if he is in heaven, he enjoys; if he is in hell, he suffers. It is his condition that determines his locality.
Henry David ThoreauHow can we remember our ignorance, which our growth requires, when we are using our knowledge all the time?
Henry David Thoreau
