This brief survey of the origin of Greek philosophy will enable us to understand the position of the Eleatics. Regarded collectively, and as a school developing a body of doctrine, they advanced in abstraction beyond any of their predecessors or contemporaries. Whereas other philosophers had sought for the abstract in phenomenal elements, the Eleatics went straight through language to the notion of pure being: even the numbers of Pythagoras were not sufficient for the exigencies of their logic. The unity of being, as the one reality, and the absolute impossibility of not-being, revealed by the consciousness and demonstrated by language in the copula ἐστί, forms the groundwork of their dogmatism. How important was the principle thus introduced into the fabric of European thought, is evident to every student of the history of philosophy. It is enough in this place to point out to what extent it has influenced our language through such words as entity, existence, essence. The Eleatics may claim as their own coinage the title of all metaphysics—Ontology, or the Science of Being.
In order to make the attitude of these earliest Greek thinkers still more clear, we must return for a moment to Heraclitus, who instituted a polemic against the Eleatic doctrine of Being. He asserted that Being is no more than not-Being. Regarded in itself as an abstraction, Being turns out to be identical with nothing. The relation of Being to not-Being in Becoming formed the central point of his metaphysic, and was enunciated in the axiom, All is flowing, πάντα ῥεῖ. Though the Heraclitean polemic was directed against the school at large, it would be in the last degree inaccurate to treat the Eleatic doctrine, as maintained by Xenophanes, Parmenides, Zeno, and Melissus, from the point of view of one consistent system. By so doing not only would the truth of history be violated, but one of the most valuable examples of the growth of thought in Greece would be lost.
Xenophanes, who is regarded as the founder of the school, was a native of Colophon. He left his fatherland, and spent the greater portion of his life in Sicily and Magna Græcia. We hear of him first at Messana, then at Catana; and there is good reason to believe that he visited the Phocæan colony of Elea (afterwards Velia) on the western coast of Calabria, a little to the south of Pæstum. At all events, antiquity spoke of him as the father of philosophy at Elea, and Diogenes Laertius mentions a poem of two thousand hexameters which he composed in joint praise of this city and Colophon. Xenophanes lived to a great age. In a couplet preserved from one of his elegies he speaks of having wandered, absorbed in thought and contemplation, for sixty-seven years through Hellas, and fixes twenty-five years as the age at which he began his travels. He was celebrated, like his fellow-countryman, Mimnermus, for his elegiac poetry, some fragments of which are among the most valuable relics we possess of that species of composition. About 538 B.C. is the date usually assigned to him.
The starting-point of philosophy for Xenophanes was found in theology. "Looking up to universal heaven," says Aristotle, "he proclaimed that unity is God." The largest fragment of his metaphysical poem consists of a polemic against polytheism, both as regards the anthropomorphic conception of deity prevalent in Greece, and also as regards the immorality attributed by Homer and Hesiod to the gods. His own god is a high abstraction of mind, one and indivisible, without motion, without beginning or ending, in no way like to man. To the divine unity he attributed thought and volition; but he does not appear to have attempted to connect God with the universe. Like the other speculators of his age and nation, he theoretically deduced the world from simple elements, choosing earth and water, as we gather from some fragments of his poem, for the primordial constituents. At the same time he held a doctrine which afterwards became the central point of Eleatic science. This was a disbelief in the evidence of the senses, a despair of empirical knowledge, which contrasts singularly with his own vehement dogmatism upon the nature of the Divine Being. Thus the originality of Xenophanes consisted in his pronouncing, without proof, that the universe must be regarded as a unity, and that this unity is the Divine Existence, all human mythology being but dreams and delusions. Of his philosophical poem only inconsiderable portions have been preserved. These, however, are sufficient to make clear the line he took, both in his assertion of monotheism and his polemic against the anthropomorphic theology of the Greeks. Such as they are, I have translated them as follows:[44]
"One god there is, among gods and men the greatest, neither in body like to mortals, nor in mind.
"With the whole of him he sees, with the whole of him he thinks, with the whole of him he hears.
"Without exertion, by energy of mind he sways the universe of things.
"That he abides forever in the same state, without movement, or change from place to place, is evident.
"But mortals fancy that gods come into being like themselves, and have their senses, voice, and body. But, of a truth, if oxen or lions had hands, and could draw with their hands, and make what men make, then horses like unto horses, and oxen like unto oxen, would both paint the images of gods, and shape their bodies also after the similitude of their own limbs.
