This article examines Bishop Berkeley's view and treatment of skepticism based on the content of his books Principles of Human Knowledge and Three Dialogues between Hylas and Philonous. It explains that the Principles of Human Knowledge was not well received when it was published in 1710 because readers and reviewers understood his denial of the existence of material substance as supporting skepticism. In his second book, Berkeley showed how he was opposed to skepticism. He also showed that there were some common principles of philosophers, and that these principles, either individually or jointly, lead to skepticism of some form.
