[Sidenote: Did Herakleitos teach a general conflagration?] 78. Most modern writers, however, ascribe to Herakleitos the doctrine of a periodical conflagration or ἐκπύρωσις, to use the Stoic term.[403] That this is inconsistent with the theory, as we have interpreted it, is obvious, and is indeed admitted by Zeller. To his paraphrase of the statement of Plato quoted above (p. 159) he adds the words: “Herakleitos did not intend to retract this principle in the doctrine of a periodic change in the constitution of the world; if the two doctrines are not compatible, it is a contradiction which he has not observed.” Now, it is in itself quite likely that there were contradictions in the discourse of Herakleitos, but it is very unlikely that there was this particular one. In the first place, it is a contradiction of the central idea of his system, the thought that possessed his whole mind (§ 67), and we can only admit the possibility of that, if the evidence for it should prove irresistible. In the second place, such an interpretation destroys the whole point of Plato’s contrast between Herakleitos and Empedokles (§ 68), which is just that, while Herakleitos said the One was always many, and the Many always one, Empedokles said the All was many and one by turns. Zeller’s interpretation obliges us, then, to suppose that Herakleitos flatly contradicted his own discovery without noticing it, and that Plato, in discussing this very discovery, was also blind to the contradiction.[404] Footnote 403: Schleiermacher and Lassalle are notable exceptions. Zeller, Diels, and Gomperz are all positive that Herakleitos believed in the ἐκπύρωσις. Footnote 404: In his fifth edition (p. 699) Zeller seems to feel this last difficulty; for he now says: “It is a contradiction which he, _and which probably Plato too_ (_und den wahrscheinlich auch Plato_) has not observed.” This seems to me still less arguable. Plato may or may not be mistaken; but he makes the perfectly definite statement that Herakleitos says ἀεί, while Empedokles says ἐν μέρει. The Ionian Muses are called συντονώτεραι and the Sicilian μαλακώτεραι just because the latter “lowered the pitch” (ἐχάλασαν) of the doctrine that this is always so (τὸ ἀεὶ ταῦτα οὕτως ἔχειν). Nor is there anything in Aristotle to set against Plato’s emphatic statement. We have seen that the passage in which he speaks of him along with Empedokles as holding that the heavens were alternately in one condition and in another refers not to the world in general, but to fire, which Aristotle identified with the substance of his own “first heaven.”[405] It is also quite consistent with our interpretation when he says that all things at one time or another become fire. This does not necessarily mean that they all become fire at the same time, but is merely a statement of the undoubted Herakleitean doctrine of the upward and downward path.[406] Footnote 405: See above, p. 177, _n._ 401.
