Three Dialogues Between Hylas and Philonous (in Opposition to Skeptics and Atheists)

George Berkeley, an Anglo-Irish philosopher, introduced the concept of "immaterialism," asserting that knowledge is limited to sensations and ideas rather than abstract notions like "matter." He famously stated, "Esse est percipi," meaning existence relies on perception. His influential works include "A Treatise Concerning the Principles of Human Knowledge" and "Three Dialogues between Hylas and Philonous," where the dialogues illustrate his philosophical debates with contemporary John Locke through the characters he created.
