"The Spanish war and other events in 1936-7 turned the scale and thereafter I knew where I stood. Every line of serious work that I have written since 1936 has been written, directly or indirectly, against totalitarianism and for democratic Socialism, as I understand it. It seems to me nonsense, in a period like our own, to think that one can avoid writing of such subjects."
