“It is surprising how much discipline is imposed upon theory by requiring that it ‘make a difference’ and provide guidance or useful illumination. I learned long ago from students in professional schools that questions of ‘so what’ or ‘what relevance does this have’ do not signify impatience with theory per se, much less anti-intellectualism, but only impatience with the obvious, general, remote, and vague statements that often parade as social science theory. One test of good theory is that it have practical implications.”
