In the range that it demanded of itself, [Caudwell's] oeuvre was indeed ingenious. But as the achievement of two short, crowded years it is remarkable. The Marxist criticism of culture is not so far advanced or so self-sufficient that it can afford to ignore it.

Helena Sheehan, Marxism and the Philosophy of Science: A Critical History

Caudwell's style is fluent, cogent and assertive
