John Yolton seeks to allow readers of Locke to have accessible in one volume sections from a wide range of Locke's books, structured so that some of the interconnections of his thought can be seen and traced. Although Locke did not write from a system of philosophy, he did have in mind an overall division of human knowledge. The readings begin with Locke's essay on Hermeneutics and the portions of his Essay Concerning Human Understanding on how to read a text. The reset of the selections are organized around Locke's division of human knowledge into natural science, ethics, and the theory of signs. Yolton's introduction and commentary explicate Locke's doctrines and provide the reader with the general background knowledge of other seventeenth-century writers and their works necessary to an understanding of Locke and his time.
