Harry Burrows Acton (2 June 1908 – 16 June 1974) was an English academic in the field of political philosophy, known for books defending the morality of capitalism, and attacking Marxism-Leninism. He in particular produced arguments on the incoherence of Marxism, which he described as a 'farrago' (in philosophical terms). His book The Illusion of the Epoch, in which this appears, is a standard point of reference. Other interests were the Marquis de Condorcet, Hegel, John Stuart Mill, Herbert Spencer, F. H. Bradley, Bernard Bosanquet and Sidney Webb. Acton also endorsed a version of negative utilitarianism, according to which the reduction of suffering has unique moral importance.
