Weber, though personally a cautious man, is an unexpected source of ideas on how to change things. He tells us how power works now and reminds us that ideas may be far more important than tools or money in changing nations. It is a hugely significant thesis. We learn that so much that we associate with vast impersonal external forces (and that hence feels entirely beyond our control) is, in fact, dependent upon something utterly intimate and perhaps more malleable: the thoughts in our own heads.
