You can soon become indifferent to the seductions of song or dance or athletic displays if you resolve the melody into its several notes, and ask yourself of each one in turn, 'Is it this that I cannot resist?' You will flinch from admitting it. Do the same for each movement or attitude of the dancers, and similarly with the athletics. In short, save in the case of virtue and its implications, always remember to go straight for the parts themselves, and by dissecting these achieve your disenchantment. And now, transfer this method to life as a whole.
