The historical version of the myths came far too rudely into collision with the popular faith, when it declared the gods directly to be men; Carneades called even their existence in question, and Epicurus denied to them at least any influence on the destinies of men. Between these systems and the Roman religion no alliance was possible; they were proscribed and remained so.

Even in the writings of Cicero it is declared the duty of a citizen to resist Euhemerism as prejudicial to religious worship; and if the Academic and the Epicurean appear in his dialogues, the former has to plead the excuse that, while as a philosopher he is a disciple of Carneades, as a citizen and pontifex he is an orthodox confessor of the Capitoline Jupiter, and the Epicurean has even ultimately to surrender and be converted. No one of these three systems became in any proper sense popular. The plain intelligible character of Euhemerism exerted doubtless a certain power of attraction over the Romans, and in particular produced only too deep an effect on the conventional history of Rome with its at once childish and senile conversion of fable into history; but it remained without material influence on the Roman religion, because the latter from the first dealt only in allegory and not in fable, and it was not possible in Rome as in Hellas to write biographies of Zeus the first, second, and third. The modern sophistry could only succeed where, as in Athens, clever volubility was indigenous, and where, moreover, the long series of philosophical systems that had come and gone had accumulated huge piles of intellectual rubbish. Against the Epicurean quietism, in fine, everything revolted that was sound and honest in the Roman character so thoroughly addressing itself to action. Yet it found more partisans than Euhemerism and the sophistic school, and this was probably the reason why the police continued to wage war against it longest and most seriously. But this Roman Epicureanism was not so much a philosophic system as a sort of philosophic mask, under which - very much against the design of its strictly moral founder - thoughtless sensual enjoyment disguised itself for good society; one of the earliest adherents of this sect, for instance, Titus Albucius, figures in the poems of Lucilius as the prototype of a Roman Hellenizing to bad purpose.

Far different were the position and influence of the Stoic philosophy in Italy. In direct contrast to these schools it attached itself to the religion of the land as closely as science can at all accommodate itself to faith. To the popular faith with its gods and oracles the Stoic adhered on principle, in so far as he recognized in it an instinctive knowledge, to which scientific knowledge was bound to have regard and even in doubtful cases to subordinate itself. He believed in a different way from the people rather than in different objects; the essentially true and supreme God was in his view doubtless the world-soul, but every manifestation of the primitive God was in its turn divine, the stars above all, but also the earth, the vine, the soul of the illustrious mortal whom the people honoured as a hero, and in fact every departed spirit of a former man. This philosophy was really better adapted for Rome than for the land where it first arose.

The objection of the pious believer, that the god of the Stoic had neither sex nor age nor corporeality and was converted from a person into a conception, had a meaning in Greece, but not in Rome. The coarse allegorizing and moral purification, which were characteristic of the Stoical doctrine of the gods, destroyed the very marrow of the Hellenic mythology; but the plastic power of the Romans, scanty even in their epoch of simplicity, had produced no more than a light veil enveloping the original intuition or the original conception, out of which the divinity had arisen - a veil that might be stripped off without special damage. Pallas Athene might be indignant, when she found herself suddenly transmuted into the conception of memory: Minerva had hitherto been in reality not much more. The supernatural Stoic, and the allegoric Roman, theology coincided on the whole in their result. But, even if the philosopher was obliged to designate individual propositions of the priestly lore as doubtful or as erroneous - as when the Stoics, for example, rejecting the doctrine of apotheosis, saw in Hercules, Castor, and Pollux nothing but the spirits of distinguished men, or as when they could not allow the images of the gods to be regarded as representations of divinity - it was at least not the habit of the adherents of Zeno to make war on these erroneous doctrines and to overthrow the false gods; on the contrary, they everywhere evinced respect and reverence for the religion of the land even in its weaknesses. The inclination also of the Stoa towards a casuistic morality and towards a systematic treatment of the professional sciences was quite to the mind of the Romans, especially of the Romans of this period, who no longer like their fathers practised in unsophisticated fashion self-government and good morals, but resolved the simple morality of their ancestors into a catechism of allowable and non-allowable actions; whose grammar and jurisprudence, moreover, urgently demanded a methodical treatment, without possessing the ability to develop such a treatment of themselves.

So this philosophy thoroughly incorporated itself, as a plant borrowed no doubt from abroad but acclimatized on Italian soil, with the Roman national economy, and we meet its traces in the most diversified spheres of action. Its earliest appearance beyond doubt goes further back; but the Stoa was first raised to full influence in the higher ranks of Roman society by means of the group which gathered round Scipio Aemilianus. Panaetius of Rhodes, the instructor of Scipio and of all Scipio's intimate friends in the Stoic philosophy, who was constantly in his train and usually attended him even on journeys, knew how to adapt the system to clever men of the world, to keep its speculative side in the background, and to modify in some measure the dryness of the terminology and the insipidity of its moral catechism, more particularly by calling in the aid of the earlier philosophers, among whom Scipio himself had an especial predilection for the Socrates of Xenophon. Thenceforth the most noted statesmen and scholars professed the Stoic philosophy - among others Stilo and Quintus Scaevola, the founders of scientific philology and of scientific jurisprudence. The scholastic formality of system, which thenceforth prevails at least externally in these professional sciences and is especially associated with a fanciful, charade-like, insipid method of etymologizing, descends from the Stoa. But infinitely more important was the new state-philosophy and state-religion, which emanated from the blending of the Stoic philosophy and the Roman religion. The speculative element, from the first impressed with but little energy on the system of Zeno, and still further weakened when that system found admission to Rome - after the Greek schoolmasters had already for a century been busied in driving this philosophy into boys' heads and thereby driving the spirit out of it - fell completely into the shade in Rome, where nobody speculated but the money-changers; little more was said as to the ideal development of the God ruling in the soul of man, or of the divine world-law. The Stoic philosophers showed themselves not insensible to the very lucrative distinction of seeing their system raised into the semi-official Roman state-philosophy, and proved altogether more pliant than from their rigorous principles we should have expected. Their doctrine as to the gods and the state soon exhibited a singular family resemblance to the actual institutions of those who gave them bread; instead of illustrating the cosmopolitan state of the philosopher, they made their meditations turn on the wise arrangement of the Roman magistracies; and while the more refined Stoics such as Panaetius had left the question of divine revelation by wonders and signs open as a thing conceivable but uncertain, and had decidedly rejected astrology, his immediate successors contended for that doctrine of revelation or, in other words, for the Roman augural discipline as rigidly and firmly as for any other maxim of the school, and made extremely unphilosophical concessions even to astrology. The leading feature of the system came more and more to be its casuistic doctrine of duties. It suited itself to the hollow pride of virtue, in which the Romans of this period sought their compensation amidst the various humbling circumstances of their contact with the Greeks; and it put into formal shape a befitting dogmatism of morality, which, like every well-bred system of morals, combined with the most rigid precision as a whole the most complaisant indulgence in the details[9]. Its practical results can hardly be estimated as much more than that, as we have said, two or three families of rank ate poor fare to please the Stoa.
