Pride works _from within_; it is the direct appreciation of oneself. Vanity is the desire to arrive at this appreciation indirectly, from without.
Arthur SchopenhauerThe happiness which we receive from ourselves is greater than that which we obtain from our surroundings. . . . The world in which a person lives shapes itself chiefly by the way in which he or she looks at it.
Arthur SchopenhauerMan is never happy, but spends his whole life in striving after something which he thinks will make him so.
Arthur SchopenhauerA man never is happy, but spends his whole life in striving after something which he thinks will make him so; he seldom attains his goal, and when he does, it is only to be disappointed; he is mostly shipwrecked in the end, and comes into harbor with mast and rigging gone. And then, it is all one whether he has been happy or miserable; for his life was never anything more than a present moment always vanishing; and now it is over.
Arthur SchopenhauerNo one knows what capacities for doing and suffering he has in himself, until something comes to rouse them to activity: just as in a pond of still water, lying there like a mirror, there is no sign of the roar and thunder with which it can leap from the precipice, and yet remain what it is; or again, rise high in the air as a fountain. When water is as cold as ice, you can have no idea of the latent warmth contained in it.
