The work of George Berkeley is marked by its diversity and range. His writings take in such topics as mathematics, psychology, politics, health, economics, deism and education, as well as that with which he is most associated - philosophy. Among the most notable of the British Empiricists, he took his starting point from Locke's 'new way of ideas', but he rejected abstract ideas and the possibility of real existence outside perception. A.C. Fraser's collection includes a series of what were previously unpublished notes by Berkeley on all the main topics of his philosophy. This, the 1901 edition, was the first complete edition of his works.
