In the age of Cato and Cicero the character of the ideal was wholly Roman, although the philosophical expression of that character was derived from the Greek Stoics. It exhibited all the force, the grandeur, the hardness, the practical tendency which Roman circumstances had early created, combined with that catholicity of spirit which resulted from very recent political and intellectual changes. In the course of time, the Greek element, which represented the gentler and more humane spirit of antiquity, gained an ascendancy. It did so by simple propagandism, aided by the long peace of the Antonines, by the effeminate habits produced by the increasing luxury, by the attractions of the metropolis, which had drawn multitudes of Greeks to Rome, by the patronage of the Emperors, and also by the increasing realisation of the doctrine of universal brotherhood, which Panætius and Cicero had asserted, but of which the full consequences were only perceived by their successors. The change in the type of virtue was shown in the influence of eclectic, and for the most part Platonic, moralists, whose special assaults were directed against the Stoical condemnation of the emotions, and in the gradual softening of the Stoical type. In Seneca the hardness of the sect, though very apparent, is broken by precepts of a real and extensive benevolence, though that benevolence springs rather from a sense of duty than from tenderness of feeling. In Dion Chrysostom the practical benevolence is not less prominent, but there is less both of pride and of callousness. Epictetus embodied the sternest Stoicism in his Manual, but his dissertations exhibit a deep religious feeling and a wide range of sympathies. In Marcus Aurelius the emotional elements had greatly increased, and the amiable qualities began to predominate over the heroic ones. We find at the same time a new stress laid upon purity of thought and imagination, a growing feeling of reverence, and an earnest desire to reform the popular religion.
