I just wanted to counter the review of the first writer on this book - this companion to Locke's thought is pitched extremely well between the needs of the new reader and a Locke scholar. Each of the articles are accessible, providing an interesting take on each of the subjects tackled. They are certainly not a simple read, however, and the reader is required to make an effort to understand the different strands of argument being discussed. The difficulties of understanding are far from insurmountable and the reader is provided with a sense of achievement in reaching a useful understanding of each subject under discussion. The articles cover all the major areas of Locke's philosophical work (with perhaps an emphasis on his epistemology and metaphysics) and there is an excellent biographical sketch. There is also a fine bibliography of Locke's works and related scholarly material. This book is a useful and informative introduction to Locke's thought. It does require an effort of understanding, but this effort is well-rewarded.
