Zeller[256] sums up his statements on this point thus: "From all that has been said it appears that the Stoics did not think of God and the world as different beings. Their system was therefore strictly pantheistic. The sum of all real existence is originally contained in God, who is at once universal matter and the creative force which fashions matter into the particular materials of which things are made. We can, therefore, think of nothing which is not either God or a manifestation of God. In point of being, God and the world are the same, the two conceptions being declared by the Stoics to be absolutely identical." The Stoic philosophy was materialism as regards the nature of things, and necessity as regards the nature of the human will. The Stoics denied the everlasting existence of souls as individuals, believing that at the end of a certain cycle they would be resolved into the Divine Being. Nevertheless, till that period arrives, they conceived the soul as existing in a future state higher and better than this. Seneca calls the day of death the birthday into this better world. In that world there would be a judgment on the conduct and character of each one; there friends would recognize each other, and renew their friendship and society. While the Epicureans considered religion in all its usual forms to be a curse to mankind, while they believed it impious to accept the popular opinions concerning the gods, while they denied any Divine Providence or care for man, while they rejected prayer, prophecy, divination, and regarded fear as the foundation of religion, they yet believed, as their master Epicurus had believed, in the existence of the immortal gods. These beings he regarded as possessing all human attributes, except those of weakness and pain. They are immortal and perfectly happy; exempt from disease and change, living in celestial dwellings, clothed with bodies of a higher kind than ours, they converse together in a sweet society of peace and content. Such were the principal theological views of the Greek philosophers. With the exception of the last, and that of the Sceptics, they were either monotheistic or consistent with monotheism. They were, on the whole, far higher than the legends of the poets or the visions of the artists. They were, as the Christian Fathers were fond of saying, a preparation for Christianity. No doubt one cause of the success of this monotheistic religion among the Greek-speaking nations was that Greek philosophy had undermined faith in Greek polytheism. This we shall consider in another section. § 7. The Worship of Greece. The public worship of Greece, as of other ancient nations, consisted of sacrifices, prayers, and public festivals. The sacrifices were for victories over their enemies, for plentiful harvests, to avert the anger of some offended deity, for success in any enterprise, and those specially commanded by the oracles.
