Note (return) — Chapter IX

Proceeding on these principles, he rejects the dualistic system of the universe, and boldly declared that all essences are fundamentally one--that, in fact, there is no real plurality, and that all the diversity which "appears" is merely presented under a peculiar aesthetic or sensible law. The senses, it is true, teach us that there are "many things," but reason affirms that, at bottom, there exists only "the one." Whatever, therefore, manifests itself in the field of sense is merely illusory--the mental representation of a phenomenal world, which to experience seems diversified, but which reason can not possibly admit to be other than "immovable" and "one." There is but one Being in the universe, eternal, immovable, absolute; and of this unconditioned being all phenomenal existences, whether material or mental, are but the attributes and modes. Hence the two great maxims of the Eleatic school, derived from Parmenides--τὰ πάντα ἕν, "The All is One" and τὸ αὐτὸ νοεῖν τε καὶ εἶναι (Idem est cogitare atque esse), "Thought and Being are identical." The last remarkable dictum is the fundamental principle of the modern pantheistic doctrine of "absolute identity" as taught by Schelling and Hegel. 451
