"This is not to say that Marx's propositions were wrong, although they were sometimes expressed so over-confidently that they licensed wrong conclusions. It was important to learn that neurosis was not caused by Satanic possession, and important to learn that human affairs did not express the mind of divine providence, or of great men, or of unfolding Ideas, or of a benevolent class-neutered market. Marx took knowledge across a threshold, pointed her towards the world, and told her to go and find out. And in that outer world, beyond the secure 'base' of the mode of production, many of the most cherished of human concerns are sited."
— E.P. Thompson, The Poverty of Theory, 161
