Uglow's book reveals how simplistic our view of groups really is. We divide them into cults and clubs, and dismiss the former for their insularity and the latter for their banality. The cult is the place where, cut off from your peers, you become crazy. The club is the place where, surrounded by your peers, you become boring. Yet if you can combine the best of those two states—the right kind of insularity with the right kind of homogeneity—you create an environment both safe enough and stimulating enough to make great thoughts possible. You get Fichte, Schelling, and Hegel, and a revolution in Western philosophy. You get Darwin, Watt, Wedgwood, and Priestley, and the beginnings of the Industrial Revolution. And sometimes, on a more modest level, you get a bunch of people goofing around and bringing a new kind of comedy to network television.
