This reaction had begun to make itself felt long before the birth of a philosophical literature in the Latin language. It may be traced to the time when the lecture-halls at Athens were first visited by Roman students, and Greek professors first received on terms of intimate companionship into the houses of Roman nobles. In each instance, but more especially in the latter, not only would the pupil imbibe new ideas from the master, but the master would suit his teaching to the tastes and capacities of the pupil. The result would be an intellectual condition somewhat resembling that which attended the popularisation of philosophy in Athens during the latter half of the fifth century B.C.; and all the more so as speculation had already spontaneously reverted to the Sophistic standpoint. The parallel will be still more complete if we take the word Sophist in its original and comprehensive sense. We may then say that while Carneades, with his entrancing eloquence and his readiness to argue both sides of a question, was the Protagoras of the new movement; Panaetius, the dignified rationalist and honoured friend of Laelius and the younger Scipio, its Prodicus; and Posidonius, the astronomer and encyclopaedic scholar, its Hippias, Phaedrus the Epicurean was its Anaxagoras or Democritus. The Epicurean philosophy was, in fact, the first to gain a footing in Rome; and it thereby acquired a position of comparative equality with the other schools, to which it was not really entitled, but which it has ever since succeeded in maintaining. The new doctrine fell like a spark on a mass of combustible material. The Romans were full of curiosity about Nature and her workings; full of contempt for the degrading Etruscan superstitions which hampered them at every turn, and the falsity of which was proving too much even for the official gravity of their state-appointed interpreters; full of impatience at the Greek mythology which was beginning to substitute itself for the severe abstractions of their own more spiritual faith;[265] full of loathing for the Asiatic orgies which were being introduced into the highest society of their own city. Epicureanism offered them a complete and easily intelligible theory of the world, which at the same time came as a deliverance from supernatural terrors. The consequence was that its different parts were thrown out of perspective, and their relative importance almost reversed. Originally framed as an ethical system with certain physical and theological implications, it was interpreted by Lucretius, and apparently also by his Roman predecessors,[266] as a scientific and anti-religious system, with certain references to conduct neither very prominently brought forward nor very distinctly conceived. And we know from the contents of the papyrus rolls discovered at Herculaneum, that those who studied the system in its original sources paid particular attention to the voluminous physical
