Philosophy dwells aloft in the Temple of Science, the divinity of its inmost shrine; her dictates descend among men, but she herself descends not : whoso would behold her must climb with long and laborious effort, nay, still linger in the forecourt, till manifold trial have proved him worthy of admission into the interior solemnities.
Thomas CarlyleUniversal history, the history of what man has accomplished in this world, is at bottom the History of the Great Men who have worked here.
Thomas Carlyle
