The 17th century was a time of epistemological revolutions. Beginning with Francis Bacon in the English tradition and Descartes in the European tradition, almost all of the philosophers of this era were concerned specifically with the matter of understanding.

Berkeley revolutionized this area of philosophy by criticizing the whole idea of understanding especially by giving a new definition of perception. Firstly I will define what idealism is and what makes an idealist from George Berkeley.
By his early 20s young George Berkeley had read Locke's Essay Concerning Human Understanding and had found it to be eminently sensible and persuasive. As regards those last two questions that Locke had posed, however, Berkeley was unconvinced that Locke's answers had been adequately thought out. Berkeley was not convinced that Locke's answers to these two questions were precisely accurate.

The two books in which he articulates his examination of these questions are The Principles of Human Knowledge , written in when Berkeley was 25 years old; and Three Dialogues Between Hylas and Philonous , written three years later when he was

This theory denies the existence of material substance and instead contends that familiar objects like tables and chairs are only ideas in the minds of perceivers and, as a result, cannot exist without being perceived.

In , 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. In this book, Berkeley's views were represented by Philonous Greek: "lover of mind" , while Hylas Greek: "matter" embodies the Irish thinker's opponents, in particular John Locke. Berkeley argued against Isaac Newton 's doctrine of absolute space , time and motion in De Motu  On Motion , published His arguments were a precursor to the views of Mach and Einstein.
