A Treatise Concerning The Principles Of Human Knowledge is a philosophical work written by George Berkeley. The book is an exploration of the nature of human perception and knowledge, and argues that all knowledge is ultimately derived from sensory experience. Berkeley's central thesis is that the material world does not exist independently of human perception, but rather is created by the mind through perception. He argues that our perceptions are the only things that we can truly know, and that the material world is simply a collection of ideas and perceptions that exist within our minds. The book is divided into three parts, with the first part outlining Berkeley's theory of perception, the second part exploring the implications of his theory for the nature of reality, and the third part addressing objections to his theory. A Treatise Concerning The Principles Of Human Knowledge is considered one of the most important works in the history of philosophy, and has had a significant impact on subsequent philosophical thought.Philosophy being nothing else but the study of wisdom and truth, it may with reason be expected that those who have spent most time and pains in it should enjoy a greater calm and serenity of mind, a greater clearness and evidence of knowledge, and be less disturbed with doubts and difficulties than other men.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
