Among these perhaps Mr. Reid's Lælius (_M. Tullii Ciceronis Lælius de Amicitia_, by James S. Reid, M.L.: Cambridge University Press, 1879) is the most notable, an edition based mainly on Seyffert's elaborate edition, yet evidently strengthened by seasonable comparison with the best German editions. Mr. Reid disowns acquaintance with any English edition of the Lælius, having only heard of that of Mr. Arthur Sidgwick, when his own was far advanced through the press. The object and purpose of the edition is twofold, viz. (1) elucidation of the subject-matter and comparison of the editor's own conclusions touching it with those of other editing scholars; and (2) a thorough elucidation of the Latinity of the dialogue, a task to which all who are cognizant of his edition of Cicero's speeches for Archias and for Balbus will admit his eminent fitness. A fourfold introduction summarises the salient points of Cicero, as a writer of philosophy; the scope of this treatise on "Friendship:" the structure, personages, and other circumstances of the dialogue, and a quasi-dramatic analysis of the same. It will be found that Cicero, whilst having no sympathy with the Epicurean philosophy of his day, sided mainly with the Peripatetics, though inclining in a few points of detail to the Stoics. An instructive disquisition on the sources of the dialogue opens out various clues to inquiring students, and suggests particularly minuter testing of the question how far Cicero directly imitated Plato's Lysis, which is perhaps more probable than that he used for it the Nicomachean Ethics, although, in form, beyond a doubt the Lælius is more Aristotelian than Platonic. The "mitis sapientia Læli" in the dialogue stands out in contrast with the genial learning of Mucius Scævola and the severer cultivation of Gaius Fannius. An interesting passage in the dialogue is that in which Lælius states a question relating to friendship, in which he was to some extent at issue with Scipio, viz., the difficulty of friendship enduring a whole lifetime. Scipio held the negative view, and Lælius demurred to it, and in c. x., xi., &c., the occurrences which tend to break off friendship are enumerated. In the tenth chapter are to be found two or three very apt elucidations of the text, such as that on the construction of "contentione condicionis," and the sense of condicio (not "conditio") in § 34, but one note (16) on "optimis quibusque" stands out as a sample of exhaustive criticism. The argument of Lælius is that there is no greater curse in friendships than, in the run of men, the desire of money; in the best, the desire of honour and glory: "in optimis quibusque honoris certamen et gloria." Let us see how Mr. Reid examines this last clause, which he compares with the sentiment, "optimus quisque gloria maxime ducitur," in the oration for Archias. The best authors, it is shown, use only the _neuter_ plural of _quisque_, and that with a superlative; Cic. Fam. vii.
