We have abundant proof that, there being substantially but two professions in the Roman republic, the military men were generally identified with the party of movement, but the lawyers were universally at the head of the party of resistance. The alliance of the lawyers with the Stoic philosophers lasted through many centuries. Some of the earliest names in the series of renowned jurisconsults are associated with Stoicism, and ultimately we have the golden age of Roman jurisprudence fixed by general consent at the era of the Antonine Caesars, the most famous disciples to whom that philosophy has given a rule of life. The long diffusion of these doctrines among the members of a particular profession was sure to affect the art which they practised and influenced. Several positions which we find in the remains of the Roman jurisconsults are scarcely intelligible, unless we use the Stoic tenets as our key; but at the same time it is a serious, though a very common, error to measure the influence of Stoicism on Roman law by counting up the number of legal rules which can be confidently affiliated on Stoical dogmas. It has often been observed that the strength of Stoicism resided not in its canons of conduct, which were often repulsive or ridiculous, but in the great though vague principle which it inculcated of resistance to passion. Just in the same way the influence on jurisprudence of the Greek theories, which had their most distinct expression in Stoicism, consisted not in the number of specific positions which they contributed to Roman law, but in the single fundamental assumption which they lent to it. After nature had become a household word in the mouths of the Romans, the belief gradually prevailed among the Roman lawyers that the old Jus Gentium was in fact the lost code of Nature, and that the Praetor in framing an Edictal jurisprudence on the principles of the Jus Gentium was gradually restoring a type from which law had only departed to deteriorate. The inference from this belief was immediate, that it was the Praetor's duty to supersede the Civil Law as much as possible by the Edict, to revive as far as might be the institutions by which Nature had governed man in the primitive state. Of course, there were many impediments to the amelioration of law by this agency. There may have been prejudices to overcome even in the legal profession itself, and Roman habits were far too tenacious to give way at once to mere philosophical theory. The indirect methods by which the Edict combated certain technical anomalies, show the caution which its authors were compelled to observe, and down to the very days of Justinian there was some part of the old law which had obstinately resisted its influence. But, on the whole, the progress of the Romans in legal improvement was astonishingly rapid as soon as stimulus was applied to it by the theory of Natural Law. The ideas of simplification and generalisation had always been associated with the
