Idealism
Idealism begins as a scandalous claim: what we call reality is not a brute mass of stuff, but is somehow inseparable from mind, spirit, or the forms in which consciousness makes a world intelligible.

Timeline
Birth of George Berkeley
**1685** — Berkeley is born in Ireland, later becoming the philosopher who will turn empiricism against matter itself. His early life belongs to the intellectual world that made idealism possible: Protestant theology, British empiricism, and the pressure to explain how experience can ground knowledge.
Publication of Berkeley's "A Treatise Concerning the Principles of Human Knowledge"
**1710** — Berkeley announces the anti-materialist idealism for which he became famous. The work argues that what we call physical objects are inseparable from perception and that the concept of matter does no explanatory work.
Publication of "Three Dialogues between Hylas and Philonous"
**1713** — Berkeley presents his arguments in dramatic form, using dialogue to expose the weaknesses of materialist assumptions. The text became one of the classic statements of subjective and immaterial idealism.
First edition of Kant's "Critique of Pure Reason"
**1781** — Kant publishes the work that redefines idealism as a critical inquiry into the conditions of possible experience. The book does not simply deny reality to the world; it relocates objectivity within the forms of human cognition.
Second edition of the "Critique of Pure Reason"
**1787** — Kant revises and clarifies the first Critique, strengthening the framework that will dominate later debates about transcendental idealism. The revised edition becomes the standard point of reference for subsequent German idealists.
Fichte develops the Wissenschaftslehre
**1794** — Fichte formulates his theory of the self-positing I, pushing idealism toward a more activist account of subjectivity. His work shifts the center of gravity from knowledge alone to agency, freedom, and practical vocation.
Schelling's early philosophy of nature and identity
**1800** — Schelling begins articulating a view of nature as dynamic, living, and continuous with spirit. His attempt to reconcile nature and consciousness becomes one of the most influential and controversial strands of German Idealism.
Publication of Hegel's "Phenomenology of Spirit"
**1807** — Hegel presents consciousness as a historical drama of conflict, recognition, and self-transformation. The book becomes a foundational text for later idealism, historical thought, and theories of social recognition.
Birth of F. H. Bradley
**1846** — Bradley is born into the Victorian intellectual world in which idealism will become the dominant philosophical idiom in Britain. He will later offer the most celebrated British defense of the absolute against atomistic empiricism.
Publication of Moore's "The Refutation of Idealism"
**1893** — Moore launches a decisive critique of British idealism by arguing that awareness and its object cannot be collapsed into one mental item. The essay helps inaugurate the analytic reaction against idealist metaphysics.
Publication of Moore's "Principia Ethica"
**1903** — Although chiefly an ethical work, it marks the consolidation of analytic clarity that displaces British idealism. Its style and method exemplify the broader philosophical shift away from monistic systems.
Revival of interest in German Idealism and British Idealism
**20th century** — Later philosophers and historians revisit idealism as a serious tradition rather than a mere prelude to analytic philosophy. New work on Hegel, Kant, and British idealists restores many of the questions idealism had posed about mind, history, and objectivity.
