John Lewis (1 February 1889 – 12 February 1976) was a British Unitarian minister and Marxist philosopher and author of many works on philosophy, anthropology, and religion.
Lewis's father, a successful builder and architect, came from a Welsh farming family, and was a very devout Methodist.
Young Lewis's social and political views clashed with those of his father.
Their quarrels eventually led to his father disinheriting him.
