The peril of every fine faculty is the delight of playing with it for pride. Talent is commonly developed at the expense of character, and the greater it grows, the more is the mischief. Talent is mistaken for genius, a dogma or system for truth, ambition for greatness, ingenuity for poetry, sensuality for art.
Ralph Waldo EmersonEvery fact is related on one side to sensation, and, on the other, to morals. The game of thought is, on the appearance of one of these two sides, to find the other: given the upper, to find the under side.
