The soul is the perceiver and revealer of truth. We know truth when we see it, let skeptic and scoffer say what they choose. Foolish people ask you, when you have spoken what they do not wish to hear, 'How do you know it is truth, and not an error of your own?' We know truth when we see it, from opinion, as we know when we are awake that we are awake.
Ralph Waldo EmersonSpurious prudence, making the senses final, is the god of sots and cowards, and is the subject of all comedy. It is nature's joke, and therefore literature's. True prudence limits this sensualism by admitting the knowledge of an internal and real world.
Ralph Waldo EmersonWhere do we find ourselves? In a series of which we do not know the extremes, and believe that it has none. We wake and find ourselves on a stair; there are stairs below us, which we seem to have ascended; there are stairs above us, many a one, which go upward and out of sight.
Ralph Waldo Emerson
