king had disappeared, but in the second chest were found two rolls of seven books each; one set was in Latin and treated of the pontifical law, the other, in Greek, dealt with Greek philosophy—tradition said it was the philosophy of Pythagoras. After solemn deliberation by the officials it was found that these books tended to destroy religion, and a timid senate ordered them to be publicly burned.[269] Again about 173 B.C., the senate required the Epicurean philosophers, Aldus and Philiscus, to leave the state;[270] and once more in 161 it passed a vote banishing the Greek philosophers and rhetoricians.[271] In 156/5 an embassy from Athens included the Peripatetic philosopher Critolaus, the Academic Carneades, and the Stoic Diogenes, who during their stay at Rome exhibited their skill in disputation and their eloquence in speeches before the people. The populace was charmed, but old fashioned people were horrified at such exhibitions. Cato the Censor was so shocked that he moved in the senate that the Roman youth should not be allowed to listen to such teachings.[272] But it was too late; philosophers might be driven from the state, but philosophy had found a foothold at Rome. The two schools that made the strongest appeal to the Romans at the end of the Republic were Epicureanism and Stoicism. The former had wide influence until the first century of our era, chiefly because its agnosticism, or rather its denial of the existence of any future life, offered a refuge from the uncertainty which prevailed now that the old beliefs were broken up and men, harrassed by political disorders, had not yet found an abiding place in any positive philosophy. The Epicureans did not deny the existence of gods, it is true, but they declared that the gods, if they existed, must dwell in some remote place in the upper ether in eternal sunshine, undisturbed by any care for mortals. They explained the universe by a resort to the atomistic materialism of Democritus, a philosopher of the late fifth century. Their religious aim, if we may so define it, was to free men from the terror which their superstitious beliefs in the gods and in future punishment brought upon them. No writer sets this forth with greater genius or with greater passion than Lucretius, the contemporary of Cicero. His six books are devoted to an explanation of the universe and its phenomena, of the nature of man, and of the impossibility of immortality. This splendid poem furnishes us the best proof that in that day the mass of men still believed in immortality and longed for an assurance that their belief was not in vain.
