" Moralizing, I observed, then, that “all that glitters is not gold.” Mr. Ballou said I could go further than that, and lay it up among my treasures of knowledge, that nothing that glitters is gold. So I learned then, once for all, that gold in its native state is but dull, unornamental stuff, and that only low-born metals excite the admiration of the ignorant with an ostentatious glitter. However, like the rest of the world, I still go on underrating men of gold and glorifying men of mica. Commonplace human nature cannot rise above that. "
