“There are some who live by every rule and cling tightly to their rectitude because they fear being swept away by a tempest of passion, and there are others who cling to the rules because they fear that there is no passion there at all, and that if they let go they would simply remain where they are, foolish and unmoved; and they could bear that least of all. Living a life of iron control lets them pretend to themselves that only by the mightiest effort of will can they hold great passions at bay.”
