It is hardly necessary to say that I do not advise all this reading in connection with the first three chapters of this book. But, as those chapters are concerned with the accepted content of morals as recognized by individuals and communities, I have a good excuse for bringing the list in here. Many other good books, not in the list, are referred to later in the volume, in other chapters. It is very convenient to have within one's reach some such book as Sidgwick's _History of Ethics_. The only fault to find with Sidgwick is that he has made his book too short, and has not given enough references. But he is admirably fair and sympathetic, as well as clear and interesting. He, who would dip more deeply into the Greek moralists, can read the accounts of the ancient egoists, Aristippus and Epicurus, in the _Lives of the Philosophers_ by that entertaining old gossip, Diogenes Laertius. The translation in Bohn's edition will serve the purpose. As for the greatest of the Greeks--a keen pleasure, intellectual and aesthetic, awaits the man who turns to Plato's _Republic_ and his _Laws_. Jowett's great translation is in every public library. And we must read Aristotle's _Nichomachean Ethics_ and his _Politics_. Here little attention is given to artistic form; but the preternatural acuteness of the man is overpowering. If we would understand some of the reasons which induced Plato and Aristotle to write of the state as they did, we can turn to chapter xiv of Grote's _Aristotle_. With certain later classical moralists most of us are more or less familiar. Seneca, in his work _On Benefits_, gives a good picture of the moral emotions and judgments of an enlightened man of his time. He was a great favorite with Christian writers later. Cicero's work, _De Officiis--On Duties_--it is best known under the Latin title, is very clear and very clever. It is, in its last half, full of "cases of conscience." I venture to suggest to the teacher of undergraduates who find ethics a dry subject, that he give them a handful of Cicero's "cases" to quarrel over. Doing just this has brought about something resembling civil war in certain classes of my undergraduates. It has done them good, and it has vastly entertained me. But each teacher must follow his own methods. We can none of us dictate. How many of us have drawn inspiration from the noble reflections contained in the _Thoughts_ of Marcus Aurelius and in the _Discourses_ of Epictetus, those great Stoics! The unadorned translations of George Long will serve to introduce us to these.
