It is in rugged crises, in unbearable endurance, and in aims which put sympathy out of the question, that the angel is shown.
Ralph Waldo EmersonYet things are knowable! They are knowable, because, being from one, things correspond. There is a scale: and the correspondence of heaven to earth, of matter to mind, of the part to the whole, is our guide. As there is a science of stars, called astronomy; and science of quantities, called mathematics; a science of qualities, called chemistry; so there is a science of sciences,--I call it Dialectic,--which is the Intellect discriminating the false and the true.
Ralph Waldo Emerson
