“For the first time in history—because of technology and mass production and distribution, and for other reasons—large numbers of people are able to have a significant measure of choice and therefore of personal control over their lives. Not the least of these choices concerns our own habits of thinking. By and large, people have welcomed that control. We belong to a society that grants to its individual members powers they have never had before, a society that takes individuals’ pleasures and pains very seriously, that exalts the self and deems personal fulfillment a legitimate goal, an almost sacred right.”
