The Graeco-Roman world was as settled and peaceful, as conscious of its imperial responsibilities, as susceptible to boredom, as greedy of amusement, could show as numerous a leisured class, and believed as firmly in money, as our own. What is more important for our purpose, it was questioning the truth of its religion as we are to-day questioning the truth of ours. Lucian was the most vehement of the questioners. Of what played the part then that the Christian religion plays now, the pagan religion was only one half; the other half was philosophy. The gods of Olympus had long lost their hold upon the educated, but not perhaps upon the masses; the educated, ill content to be without any guide through the maze of life, had taken to philosophy instead. Stoicism was the prevalent creed, and how noble a form this could take in a cultivated and virtuous mind is to be seen in the _Thoughts_ of M. Aurelius. The test of a religion, however, is not what form it takes in a virtuous mind, but what effects it produces on those of another sort. Lucian applies the test of results alike to the religion usually so called, and to its philosophic substitute. He finds both wanting; the test is not a satisfactory one, but it is being applied by all sorts and conditions of men to Christianity in our own time; so is the second test, that of inherent probability, which he uses as well as the other upon the pagan theology; and it is this that gives his writings, even apart from their wit and fancy, a special interest for our own time. Our attention seems to be concentrated more and more on the ethical, as opposed to the speculative or dogmatic aspect of religion; just such was Lucian's attitude towards philosophy.
