ONE:
TWO:Thus the final effect of its communion with the Roman mind was not so much to develope Greek philosophy any further, or to reconcile its warring sects with one another, as to aid in their decomposition by throwing them back on the184 earlier forms whence they had sprung. Accordingly we find that the philosophic activity of Hellas immediately before and after the Christian eraso far as there was any at allconsisted in a revival of the Pythagorean and Cynic schools, accompanied by a corresponding resuscitation of primitive Scepticism. This last takes the shape of a very distinct protest against the fashionable naturalism of the age, just as the scepticism of Protagoras and Gorgiasif our view be correcthad once been called forth by the naturalism of Prodicus and Hippias. The principal representative, if not the founder, of Neo-Scepticism was Aenesidmus, who taught in Alexandria, when we are not informed, but probably after the middle of the first century A.D.291 An avowed disciple of Pyrrho, his object was to reassert the sceptical principle in its original purity, especially as against the Academicians, whom he charged with having first perverted and then completely abandoned it.292 Aenesidmus would hear nothing of probabilities nor of moral certainties. He also claimed to distinguish himself from the Academicians by refusing to assert even so much as that nothing can be asserted; but it appears that, in this point, he had been fully anticipated by Arcesilaus and Carneades.293 For the rest, his own Scepticism recalls the method of Gorgias and Protagoras much more distinctly than the method of the New Academya fresh illustration of the archaic and revivalist tendencies displayed by philosophy at185 this period. In other words, it is not against the reasoning processes that his criticisms are directed, but against the theory of causation on the objective side, and against the credibility of our immediate perceptions on the subjective side.294 But, in both directions, he has worked out the difficulties of the old Sophists with a minuteness and a precision unknown to them; and some of his points have been found worth repeating in a different connexion by modern critics. Thus, in analysing the theory of causation, he draws attention to the plurality of causes as an obstacle to connecting any given consequent with one antecedent more than with another; to the illegitimate assumption that the laws inferred from experience hold good under unknown conditions; to the arbitrary assumption of hypothetical causes not evinced by experience; and to the absurdity of introducing a new difficulty for the purpose of explaining an old one.295 With regard to causation itself, Aenesidmus seems to have resolved it into action and reaction, thus eliminating the condition of186 antecedence and consequence, without which it becomes unintelligible.296Another science which has only been cultivated on a large scale within comparatively recent years has confirmed the views suggested by jurisprudence. An enormous mass of inscriptions has been brought to light, deciphered, collated, and made available by transcription for the purposes of sedentary scholars. With the help of these records, fragmentary though they be, we have obtained an insight into the sentiments, beliefs, and social institutions of Pagan antiquity as it was just before the conversion of the Roman world to Christianity, such as literature alone could not supply. Literature and history, too, have told a somewhat different story when read over again in the light of these new discoveries. Finally, the whole mine of materials, new and old, has been worked by a class of enquirers who bring to their task qualities nearly unknown among the scholars of a former generation. These men are familiar with an immense range of studies lying outside their special subject, but often capable of affording it unexpected illustrations; they are free from theological prejudices; they are sometimes versed in the practical conduct of state affairs; and habits of wide social intercourse have emancipated them from the narrowing associations incident to a learned profession.
