Roberts first defends Berkeley's claim that in fact, his philosophy does square with commonsense (the beliefs of what he and Berkeley call "the mob"). He then defends Berkeley's positive metaphysics, which was that reality consists of spiritual substances, not material ones. Lastly, Roberts emphasizes the importance of the distinction between the active and passive in Berkeley's system, and connects Berkeley's views on language and meaning to future figures like Austin and Wittgenstein.

""The book will, I believe, become a central work in Berkeley scholarship and in the area of early modern philosophy. It is a pleasure to read. It is written in a clear, non-stuffy, often elegant, and sometimes even witty style. It shows an extraordinary grasp of both the primary and secondary literature of early modern philosophy."—Robert J. Fogelin, Dartmouth College"
