There is, indeed, nothing more nobly characteristic of the Hellenic spirit, especially as organised by Socrates, than its capacity not only for communicating, but for awakening ideas; thus enabling all the nations among which it spread to realise the whole potential treasure of theoretical and practical energy with which they were endowed. And, from this point of view, we may say that what seems most distinctively proper to Rome—the triumphant consciousness of herself as a world-conquering and world-ruling power—came to her from Greece, and under the form of a Greek idea, the idea of providential destiny. It was to make his countrymen understand the fateful character and inevitable march of her empire that Polybius composed his great history; it was also by a Greek that the most successful of her early national epics was sung; and when at last her language was wrought into an adequate instrument of literary expression—thanks also to Greek rhetorical teaching,—and the culture of her children had advanced so far that they could venture to compete with the Greeks on their own ground, it was still only under forms suggested by Stoicism that Virgil could rewrite the story of his country’s dedication to her predestined task. That Virgil was acquainted with this philosophy and had accepted some of its principal conclusions is evident from a famous passage in the Sixth _Aeneid_,[282] setting forth the theory of a universal and all-penetrating soul composed of fiery matter, whence the particular souls of men and animals are derived, by a process likened to the scattering and germination of seeds; from another equally famous passage in the Fourth _Eclogue_,[283] describing the periodical recurrence of events in the same order as before; and also, although to a less extent, from his acceptance of the Stoic astronomy in the _Georgics_;[284] a circumstance which, by the way, renders it most unlikely that he looked up to Lucretius as an authority in physical science.[285] But even apart from this collateral evidence, one can see that the _Aeneid_ is a Stoic poem. It is filled with the ideas of mutation and vicissitude overruled by a divinely appointed order; of the prophetic intimations by which that order is revealed; of the obedience to reason by which passion is subdued; and of the faith in divine goodness by which suffering is made easy to be borne. And there are also gleams of that universal humanity familiar to Stoicism, which read to some like an anticipation of the Christian or the modern spirit, but which really resemble them only as earlier manifestations of the same great philosophical movement.
