“And even couldst thou have broken through that formidable web, with thy gnat’s wings, thou believest that thou couldst have reached the light? Alas! that pane of glass which is further on, that transparent obstacle, that wall of crystal, harder than brass, which separates all philosophies from the truth, how wouldst thou have overcome it? Oh, vanity of science! how many wise men come flying from afar, to dash their heads against thee! How many systems vainly fling themselves buzzing against that eternal pane!”
