"Richmond's Reader's Guide is the perfect companion for those students approaching Berkeley's Principles of Human Knowledge for the first time. In a clear, unpretentious and often unobtrusively witty style, Richmond takes the reader through the work paragraph by paragraph, explaining its meaning, often by appeal to Berkeley's notebooks and other works. He asks the reader stimulating questions to help them engage with the text, and usefully sketches Berkeley's intellectual background and the fortunes of the work's reception. This is a book truly written with students in mind, and all the better for that." - Dr Peter Kail, University of Oxford, UK
