I have made a large Index to this book; and any per~ son, who has the necessary industry, may find in it almost every passage in the Discourses in which the Opinions of the philosopher are stated; and thus he may acquire a general notion of the philosophical system of Epictetus. But few readers will have the time and the inclination for this labor, and therefore I shall attempt to do the work for them. I have found two expositions of the system of Epic tetus. One is by Dr. Heinrich Ritter in his Geschichte der Philosophie alter Zeit, Vierter Theil, 1839. The other is by Professor Christian A. Brandis.' Both of these expositions are useful; and I have used them. I do not think that either of them is complete, nor will mine be. I shall not make my exposition exactly in the same form as either of them; nor shall I begin it in the same way.
