much good there is in friendship. It is said that a certain philosopher of Agrigentum [Footnote: Empedocles. Only a few fragments of his great poem are extant. His theory seems like a poetical version of Newton's law of universal gravitation. The analogy between physical attraction and the mutual attraction of congenial minds and souls has its record in the French word _aimant_, denoting _loadstone_ or _magnet_.] sang in Greek verse that it is friendship that draws together and discord that parts all things which subsist in harmony, and which have their various movements in nature and in the whole universe. The worth and power of friendship, too, all mortals understand, and attest by their approval in actual instances. Thus, if there comes into conspicuous notice an occasion on which a friend incurs or shares the perils of his friend, who can fail to extol the deed with the highest praise? What shouts filled the whole theatre at the performance of the new play of my guest [Footnote: Or _host_; for the word _hospes_ may have either meaning. It denotes not the fact of giving or receiving hospitality, but the permanent and sacred relation established between host and guest. This relation has lost much of its character in modern civilization, and I doubt whether it has a name in any modern European language.] and friend Marcus Pacuvius, when--the king not knowing which of the two was Orestes--Pylades said that he was Orestes, while Orestes persisted in asserting that he was, as in fact he was, Orestes! [Footnote: Among the many and conflicting legends about Orestes is that which seems to have been the theme of the lost tragedy of Pacuvius. Orestes, after avenging on his mother and her paramour the murder of his father, in order to expiate the guilt of matricide, was directed by the Delphian oracle to go to Tauris, and to steal and transport to Athens an image of Artemis that had fallen from heaven. His friend Pylades accompanied him on this expedition. They were seized by Thoas the king, and Orestes, as the principal offender, was to be sacrificed to Artemis. His sister, Iphigeneia, priestess of Artemis, contrived their escape, and the three arrived safe at Athens with the sacred image.] The whole assembly rose in applause at this mere fictitious representation. What may we suppose that they would have done, had the same thing occurred in real life? In that case Nature herself displayed her power, when men recognized that as rightly done by another, which they would not have had the courage to do themselves. Thus far, to the utmost of my ability as it seems to me, I have given you my sentiments concerning friendship. If there is more to be said, as I think that there is, endeavor to obtain it, if you see fit, of those who are wont to discuss such subjects.
