When we can drain the Ocean into mill-ponds, and bottle up the Force of Gravity, to be sold by retail, in gas jars; then may we hope to comprehend the infinitudes of man's soul under formulas of Profit and Loss; and rule over this too, as over a patent engine, by checks, and valves, and balances.
Thomas CarlyleThe Great Man's sincerity is of the kind he cannot speak of, is not conscious of: nay, I suppose, he is conscious rather of insincerity; for what man can walk accurately by the law of truth for one day? No, the Great Man does not boast himself sincere, far from that; perhaps does not ask himself if he is so: I would say rather, his sincerity does not depend on himself; he cannot help being sincere!
Thomas Carlyle
