36. On the other hand, it would be wrong to suppose that Orphicism or the Mysteries suggested any definite doctrines to philosophers, at least during the period which we are about to consider. We have admitted that they really implied a new view of the soul, and we might therefore have expected to find that they profoundly modified men’s theory of the world and their relation to it. The striking thing is that this did not happen. Even those philosophers who were most closely in touch with the religious movement, like Empedokles and the Pythagoreans, held views about the soul which really contradicted the theory implied by their religious practices.[182] There is no room for an immortal soul in any philosophy of this period. Up to Plato’s time immortality was never treated in a scientific way, but merely assumed in the Orphic rites, to which Plato half seriously turns for confirmation of his own teaching.[183] Footnote 182: For Empedokles, see § 119; for the Pythagoreans, see § 149. Footnote 183: Cf. _Phd._ 69 c 2, καὶ κινδυνεύουσι καὶ οἱ τὰς τελετὰς ἡμῖν οὗτοι καταστήσαντες οὐ φαῦλοί τινες εἶναι, ἀλλὰ τῷ ὄντι πάλαι αἰνίττεσθαι κ.τ.λ. The gentle irony of this and similar passages ought to be unmistakable. All this is easily accounted for. With us a religious revival generally means the vivid realisation of a new or forgotten doctrine, while ancient religion has properly no doctrine at all. “The initiated,” Aristotle said, “were not expected to learn anything, but merely to be affected in a certain way and put into a certain frame of mind.”[184] Nothing was required but that the ritual should be correctly performed, and the worshipper was free to give any explanation of it he pleased. It might be as exalted as that of Pindar and Sophokles, or as material as that of the itinerant mystery-mongers described by Plato in the _Republic_. The essential thing was that he should duly sacrifice his pig. Footnote 184: Arist. fr. 45, 1483 a 19, τοὺς τελουμένους οὐ μαθεῖν τι δεῖν, ἀλλὰ παθεῖν καὶ διατεθῆναι. I.
