As might be expected from the immense exuberance of their intellectual life, we find every kind of scepticism represented among the Greeks; and, as with their other philosophical tendencies, there is evidence of its existence previous to or independent of scientific speculation. Their very religion, though burdened with an enormous mass of fictitious legends, shows a certain unwillingness to transgress the more obvious laws of nature, not noticeable in the traditions of kindred or neighbouring races. Its tendency is rather to imagine supernatural causes for natural events, or to read a divine meaning into accidental occurrences, than to introduce impossibilities into the ordinary course of history. And some of its most marvellous stories are told in such a manner that the incredulous satire with which they were originally received is, by a beautiful play of irony, worked into the very texture of the narrative itself. For example, the Greeks were especially disinclined to believe that one of the lower animals could speak with a human voice, or that a dead man could be brought back to life—contradicted as both suppositions were by the facts of universal experience. So when the horse Xanthus replies to his master’s reproaches, Homer adds that his voice was arrested by the Erinyes—that is to say, by the laws of nature; and we may suspect that nothing more is intended by his speech than the interpretation which Achilles would spontaneously put on the mute and pathetic gaze of the faithful steed. And when, to illustrate the wondrous medical skill of Asclêpius, it is related that at last he succeeded in restoring a dead man to life, the story adds that for this impious deed both the healer and his patient were immediately transfixed by a thunderbolt from heaven.[215] Another impossibility is to predict with any certainty the future fate of individuals, and here also—as has been already observed in a different connexion[216]—the Greeks showed their extreme scepticism with regard to any alleged contravention of a natural law, under the transparent disguise of stories about persons whom ambiguous predictions had lured to their fall.
