"The world may be explained in sociological terms. David Riesman describes three basic social personalities in The Lonely Crowd. 'Other-directed' people pattern their behavior on what their peers expect of them. Suburban America's men in gray-flannel suits are other-directed. 'Inner-directed' people are guided by what they have been trained to expect of themselves. [General Douglas] MacArthur was inner-directed. The third type, the 'tradition-directed,' has not been seen in the West since the Middle Ages. Tradition-directed people hardly think of themselves as individuals; their conduct is determined by folk rituals handed down from the past."
