G.E. Moore
G. E. Moore made philosophy put its hands where its mouth was: if skepticism says you do not know the world is real, Moore replies by raising his hand, then asking which is more certain—the hand, or the argument that denies it.

Timeline
Birth of G. E. Moore
**1873-04-04** — George Edward Moore is born in London, entering the Victorian world that would later supply both the intellectual background and the targets of his philosophical revolt. His eventual role in Cambridge philosophy begins in a culture still shaped by idealism and moral seriousness.
Matriculation at Trinity College, Cambridge
**1892** — Moore enters Trinity College and encounters the philosophical environment that will shape his anti-Idealist turn. Cambridge becomes the setting in which his insistence on clarity and common sense begins to take form.
Publication of Principia Ethica
**1903** — Moore publishes his landmark ethical work, introducing the open question argument and the naturalistic fallacy. The book becomes one of the foundations of twentieth-century analytic ethics and a major challenge to moral reductionism.
Encounters with Bertrand Russell in the anti-Idealist revolt
**1903** — Around this period, Moore and Russell jointly help shift Cambridge away from British Idealism toward analysis and logical clarity. Their exchange becomes one of the engines of early analytic philosophy.
Essay on 'The Nature of Judgment' and the rise of analytical method
**1905** — Moore’s work contributes to a broader reorientation in philosophy toward careful analysis of propositions and concepts. His approach helps establish the style that later becomes characteristic of analytic philosophy.
Proof of an External World
**1939** — Moore presents his famous anti-skeptical paper, arguing that he can prove the existence of external things by holding up his hands. The paper becomes a canonical text in debates over skepticism and common sense.
War-time philosophical influence and the Cambridge generation
**1941** — Moore’s influence continues through students and interlocutors who develop ordinary-language and epistemological approaches in response to his work. His methods help shape the intellectual style of mid-century analytic philosophy.
Publication of Wittgenstein's On Certainty after Moore's challenge
**1951** — Wittgenstein’s late reflections on certainty, developed in dialogue with Moore’s skepticism arguments, reframe the issue of common sense and hinge propositions. Moore becomes a central foil for later philosophy of knowledge and language.
Death of G. E. Moore
**1958-10-24** — Moore dies, leaving behind a compact but transformative body of work in epistemology, ethics, and the methodology of analysis. His reputation quickly settles into that of a foundational, if not always decisive, analytic philosopher.
Postwar revival of Moorean epistemology
**1969** — Later analytic philosophers revisit Moore’s common-sense arguments as debates over skepticism, justification, and ordinary knowledge intensify. His approach remains a live option in epistemology, even where his specific proofs are rejected.
Ordinary-language and hinge epistemology debates expand
**1970** — The reception of Wittgenstein’s On Certainty deepens discussion of Moore’s place in twentieth-century philosophy. The question shifts from whether Moore refuted skepticism to what his gesture reveals about certainty, practice, and language.
Moore's ethics and realism re-enter contemporary debate
**2000** — Contemporary moral realism and non-naturalism renew interest in Moore’s arguments against reductionism and in the open question argument. His work continues to function as a benchmark for both defenders and critics of irreducible value.
