"The sociological imagination, I remind you, in considerable part consists of the capacity to shift from one perspective to another, and in the process to build up an adequate view of a total society and of its components. It is this imagination, of course, that sets off the social scientist from the mere technician. Adequate technicians can be trained in a few years. The sociological imagination can also be cultivated; certainly it seldom occurs without a great deal of often routine work. Yet there is an unexpected quality about it, perhaps because its essence is the combination of ideas that no one expected were combinable--say, a mess of ideas from German philosophy and British economics. There is a playfulness of mind back of such combining as well as a truly fierce drive to make sense of the world, which the technician as such usually lacks."
