Men do not know the natural disease of the mind; it does nothing but ferret and inquire, and is eternally wheeling, juggling, and perplexing itself like silkworms, and then suffocates itself in its work; It thinks it discovers at a great distance, I know not what glimpses of light and imaginary truth: but whilst running to it, so many difficulties, hindrances, and new inquisitions cross it, that it loses its way, and is made drunk with the motion.
