George Berkeley
George Berkeley made a daring philosophical wager: if we strip away the comforting fiction of material substance, the world does not disappear but becomes more intimate, more disciplined, and far more difficult to explain than common sense had imagined.

Timeline
Berkeley is born in County Kilkenny
**1685-03-12** — George Berkeley is born into the Anglo-Irish world that will shape both his clerical career and his philosophical horizons. The political and religious tensions of Ireland form part of the background to his lifelong concern with order, authority, and certainty.
Berkeley enters Trinity College Dublin
**1700** — At Trinity College, Berkeley receives the education that will anchor his work in logic, theology, and the new philosophy. The college environment places him in direct contact with the intellectual materials that he will later transform.
An Essay towards a New Theory of Vision appears
**1709** — Berkeley publishes his early analysis of visual perception, arguing that distance is not directly seen but learned through association. The work announces the perceptual and anti-abstraction themes that will later govern his metaphysics.
The Principles of Human Knowledge is published
**1710** — Berkeley states his immaterialist thesis with maximum force, rejecting material substance and advancing the claim that the sensible world consists in ideas perceived by minds. This book becomes the central text for all later debates about Berkeley.
Three Dialogues between Hylas and Philonous is published
**1713** — Berkeley presents his views in dramatic dialogue, turning abstract metaphysics into a contest between a materialist and an immaterialist. The work refines his position and makes it more accessible while preserving its rigor.
Berkeley travels in Europe and enters wider intellectual circles
**1713-01-01** — During his travels on the Continent, Berkeley encounters intellectual and cultural worlds beyond Ireland and England. These experiences broaden the context in which his philosophy will later be read and discussed.
Berkeley is ordained in the Church of Ireland
**1714** — Ordination confirms the theological framework that underwrites his philosophy. His immaterialism is not a retreat from religion but an attempt to make the world more intelligible within it.

Berkeley dies in Oxford
**1753-01-14** — Berkeley dies after decades of philosophical, clerical, and educational work. His arguments against matter continue to provoke both ridicule and admiration, ensuring that his thought remains active in later philosophy.
