Moore's approach to philosophizing involved focusing on narrow problems and avoiding grand synthesis. His method was to scrutinize the meanings of the key terms in which philosophers expressed themselves while maintaining an implicit commitment to the ideals of clarity, rigor, and argumentation.

It is upon The Gamester that Moore's literary reputation rests; the play was much-produced in England and the United States in the century after Moore's death. The oft-quoted phrase "rich beyond the dreams of avarice" is spoken by Mrs. Beverley in the play's second act.

Edward Forrest Moore (November 23, 1925 in Baltimore, Maryland – June 14, 2003 in Madison, Wisconsin) was an American professor of mathematics and computer science, the inventor of the Moore finite state machine, and an early pioneer of artificial life.

Especially in Principia Ethica, Moore spent much more time defending his other non-naturalist thesis, about the autonomy of ethics, which he expressed by saying the property of goodness is simple and unanalyzable, and in particular unanalyzable in non-moral terms.
