Cyril attended meetings of the Communist Party while a student at University College London in 1947, but was repelled what he saw as double-talk, lies and sectarianism. He then joined the Revolutionary Communist Party, and was a Trotskyist up until supporting the expulsion of Gerry Healy from the WRP in 1985. Cyril subsequently embarked on a thoroughgoing re-examination of his understanding of Marxism, culminating in “Marx at the Millennium,” published by Pluto Press in 1996. This work sought to strip the layers of interpretation and distortion covering the work of Karl Marx, and highlighted the need for a fresh study of Marx's writing. “Karl Marx and the Future of the Human,” was published by Lexington in 2004. Cyril taught statistics at the London School of Economics for many years until his retirement in the early 1990s and has given talks and written numerous magazine articles on themes relating to science, philosophy, economics and communism.
