It is in virtue of his own desires and curiosities that any man continues to exist with even patience, that he is charmed by the look of things and people, and that he wakens every morning with a renewed appetite for work and pleasure. Desire and curiosity are the two eyes through which he sees the world in the most enchanted colours...and the man may squander his estate and come to beggary, but if he keeps these two amulets he is still rich in the possibilities of pleasure.
