ἐν τῷ σοὶ παύω πιστὸν λόγον ἠδὲ νόημα
ἀμφὶς ἀληθείης· δόξας δ’ ἀπὸ τοῦδε βροτείας
μάνθανε, κόσμον ἐμῶν ἐπέων ἀπατηλὸν ἀκούων.

[72] Aristotle (Metaphys. A. 5, p. 987, a. 1) represents Parmenides as assimilating one of his phenomenal principles (Heat) to Ens. and the other (Cold) to Non-Ens. There is nothing in the fragments of Parmenides to justify this supposed analogy. Heat as well as Cold belongs to Non-Ens, not to Ens, in the Parmenidean doctrine. Moreover Cold or Dense is just as much a positive principle as Hot or Rare, in the view of Parmenides; it is the female to the male (Parm. Fragm. v. 129; comp. Karsten, p. 270). Aristotle conceives Ontology as a substratum for Phenomenology; and his criticisms on Parmenides imply (erroneously in my judgment) that Parmenides did the same. The remarks which Brucker makes both on Aristotle’s criticism and on the Eleatic doctrine are in the main just, though the language is not very suitable.

Brucker, Hist. Philosoph., part ii. lib. ii. ch. xi. tom. 1, p. 1152-3, about Xenophanes:—“Ex iis enim quæ apud Aristotelem ex ejus mente contra motum disputantur, patet Xenophanem motûs notionem aliam quam quæ in physicis obtinet, sibi concepisse; et ad verum motum progressum a nonente ad ens ejusque existentiam requisivisse. Quo sensu notionis hujus semel admisso, sequebatur (cum illud impossibile sit, ut ex nihilo fiat aliquid) universum esse immobile, adeoque et partes ejus non ita moveri, ut ex statu nihili procederent ad statum existentiæ. Quibus admissis, de rerum tamen mutationibus disserere poterat, quas non alterationes, generationes, et extinctiones, rerum naturalium, sed modificationes, esse putabat: hoc nomine indignas, eo quod rerum universi natura semper maneret immutabilis, soliusque materiæ æternum fluentis particulæ varie inter se modificarentur. Hâc ratione si Eleaticos priores explicemus de motu disserentes, rationem facile dabimus, quî de rebus physicis disserere et phenomena naturalia explicare, salvâ istâ hypothesi, potuerint. Quod tamen de iis negat Aristoteles, conceptum motûs metaphysicum ad physicum transferens: ut, more suo, Eleatico systemate corrupto, eò vehementius illud premeret.”

[73] Parmenides, ap. Simplik. ad Aristot. Physic. fol. 9 a.

ἐν δὲ μέσῳ τούτων Δαιμων, ἣ πάντα κυβερνᾷ, &c.

Plutarch, Amator, 13.

[74] See especially the remarkable passage from Stobæus, Eclog. Phys. i. 23, p. 482, cited in Karsten, Frag. Parm. p. 241, and Cicero, De Natur. Deor, i. 11, s. 28, with the Commentary of Krische, Forschungen auf dem Gebiete der alten Philosophie, viii. p. 98, seqq.

It is impossible to make out with any clearness the Kosmos and its generation as conceived by Parmenides. We cannot attain more than a general approximation to it.

[75] Diogen. Laert. ix. 21, viii. 48; Strabo, ii. p. 93 (on the authority of Poseidonius). Plutarch (Placit. Philos. iii. 11) and others ascribe to Parmenides the recognition not of five zones, but only of two. If it be true that Parmenides held this opinion about the figure of the earth, the fact is honourable to his acuteness; for Leukippus, Anaxagoras, Archelaus, Diogenes the Apolloniate, and Demokritus, all thought the earth to be a flat, round surface, like a dish or a drum: Plato speaks about it in so confused a manner that his opinion cannot be made out: and Aristotle was the first who both affirmed and proved it to be spherical. The opinion had been propounded by some philosophers earlier than Anaxagoras, who controverted it. See the dissertation of L. Oettinger. Die Vorstellungen der Griechen über die Erde als Himmelskörper, Freiburg, 1850, p. 42-46.
