Three Dialogues Between Hylas and Philonous in Opposition to Sceptics and Atheists

George Berkeley (1685-1753) was an Irish philosopher, an anglican bishop and one of the three great British empiricists along with John Locke and David Hume. Ignored and derided in life, he is now widely re-evaluated and considered as a sort of indirect precursor of Ernst Mach, Albert Einstein and Niels Bohr for his thesis on the non-existence of matter and the impossibility of an objectively absolute time and space. His critiques of mathematics and science are among the most controversial, brilliant and revolutionary in the history of philosophy.In 1709 Berkeley published his first major work, An Essay Towards a New Theory of Vision, in which he discussed the limitations of human vision and advanced the theory that the proper objects of sight are not material objects, but light and colour. This foreshadowed his chief philosophical work, A Treatise Concerning the Principles of Human Knowledge, in 1710, which, after its poor reception, he rewrote in dialogue form and published under the title Three Dialogues Between Hylas and Philonous in 1713. In this book, Berkeley’s views were represented by Philonous (Greek: “lover of mind”), while Hylas (“hyle”, Greek: “matter”) embodies the Irish thinker’s opponents, in particular John Locke.In the opinion of most scholars and academics, Three Dialogues Between Hylas and Philonous stands as one of the most brilliant, accessible, and provocative works in the history of Western philosophy. Written in a lively conversational style modeled after Plato, the work serves as a defense and popularization of the radical Berkeley’s philosophy.
