APPENDIX.
This is one of the dialogues declared to be spurious by Schleiermacher, Ast, Socher, and Stallbaum, all of them critics of the present century. In my judgment, their grounds for such declaration are altogether inconclusive. They think the dialogue an inferior composition, unworthy of Plato; and they accordingly find reasons, more or less ingenious, for relieving Plato from the discredit of it. I do not think so meanly of the dialogue as they do; but even if I did, I should not pronounce it to be spurious, without some evidence bearing upon that special question. No such evidence, of any value, is produced.
It is indeed contended, on the authority of a passage in Diogenes (ix. 37), that Thrasyllus himself doubted of the authenticity of the Erastæ. The passage is as follows, in his life of Demokritus — εἴπερ οἱ Ἀντερασταὶ Πλάτωνός εἰσι, φησὶ Θράσυλλος, οὗτος ἂν εἴη ὁ παραγενόμενος ἀνώνυμος, τῶν περὶ Οἰνοπίδην καὶ Ἀναξαγόραν ἕτερος, ἐν τῇ πρὸς Σωκράτην ὁμιλίᾳ διαλεγόμενος περὶ φιλοσοφίας· ᾧ, φησίν, ὡς πεντάθλῳ ἔοικεν ὁ φιλόσοφος· καὶ ἦν ὡς ἀληθῶς ἐν φιλοσοφίᾳ πένταθλος (Demokritus).
Now in the first place, Schleiermacher and Stallbaum both declare that Thrasyllus can never have said that which Diogenes here makes him say (Schleierm. p. 510; Stallbaum, Prolegg. ad. Erast. p. 266, and not. p. 273).
Next, it is certain that Thrasyllus did consider it the undoubted work of Plato, for he enrolled it in his classification, as the third dialogue in the fourth tetralogy (Diog. L. iii. 59).
Yxem, who defends the genuineness of the Erastæ (Ueber Platon’s Kleitophon, pp. 6-7, Berlin, 1846), insists very properly on this point; not merely as an important fact in itself, but as determining the sense of the words εἴπερ οἱ Ἀντερασταὶ Πλάτωνός εἰσι, and as showing that the words rather affirm, than deny, the authenticity of the dialogue. “If the Anterastæ are the work of Plato, as they are universally admitted to be.” You must supply the parenthesis in this way, in order to make Thrasyllus consistent with himself. Yxem cites a passage from Galen, in which εἴπερ is used, and in which the parenthesis must be supplied in the way indicated: no doubt at all being meant to be hinted. And I will produce another passage out of Diogenes himself, where εἴπερ is used in the same way; not as intended to convey the smallest doubt, but merely introducing the premiss for a conclusion immediately following. Diogenes says, respecting the Platonic Ideas, εἴπερ ἐστὶ μνήμη, τὰς ἰδέας ἐν τοῖς οὖσιν ὑπάρχειν (iii. 15). He does not intend to suggest any doubt whether there be such a fact as memory. Εἴπερ is sometimes the equivalent of ἐπειδήπερ: as we learn from Hermann ad Viger. VIII. 6, p. 512.
There is therefore no fair ground for supposing that Thrasyllus doubted the genuineness of the Erastæ. And when I read what modern critics say in support of their verdict of condemnation, I feel the more authorised in dissenting from it. I will cite a passage or two from Stallbaum.
Stallbaum begins his Prolegomena as follows, pp. 205-206: “Quanquam hic libellus genus dicendi habet purum, castum, elegans, nihil ut inveniri queat quod à Platonis aut Xenophontis elegantiâ, abhorreat — tamen quin à Boeckhio, Schleiermachero, Astio, Sochero, Knebelio, aliis jure meritoque pro suppositicio habitus sit, haudquaquam dubitamus. Est enim materia operis adeo non ad Platonis mentem rationemque elaborata, ut potius cuivis alii Socraticorum quam huic rectè adscribi posse videatur.”
