Either we limit our studies to the kind of thing a single man can readily do, and work within the bounds of traditional disciplines, or we boldly try to understand society, and to that end use all the materials and techniques available. Before long those who choose the latter alternative—which, under the press of events, seems to be chosen for them . . . will use each other’s materials and they will do what human limitations made necessary: work together on large projects, using their professional skills in common and educating each other. —Ralph Gilbert Ross (1952:28)
