What a man can do and suffer is unknown to himself till some occasion presents itself which draws out the hidden power. Just as one sees not in the water of an unruffled pond the fury and roar with which it can dash down a steep rock without injury to itself, or how high it is capable of rising; or as little as one can suspect the latent heat in ice-cold water.
Arthur SchopenhauerPride is an established conviction of oneโs own paramount worth in some particular respect, while vanity is the desire of rousing such a conviction in others, and it is generally accompanied by the secret hope of ultimately coming to the same conviction oneself. Pride works from within; it is the direct appreciation of oneself. Vanity is the desire to arrive at this appreciation indirectly, from without.
Arthur Schopenhauer
