Christopher Hill said this quote

Historians are interested in ideas not only because they influence societies, but because they reveal the societies that give rise to them.

~ Christopher Hill

The radicals assumed that acting was more important than speaking. Talking and writing books, Winstanley insisted, is 'all nothing and must die; for action is the life of all, and if thou dost not act, thou dost nothing.' It is a thought worth pondering by those who read books about the seventeenth-century radicals, no less than by those who write them. Were you doers or talkers only? Bunyan asked his generation. What canst thou say?
