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 SchopenhauerEvery man takes the limits of his own field of vision for the limits of the world.
Arthur SchopenhauerEvery human perfection is allied to a defect into which it threatens to pass, but it is also true that every defect is allied to a perfection.
Arthur Schopenhauer
