Neander divides Israel at the date of Christ into three sections:—
1. Pharisaism, the "dead theology of the letter."
2. Sadduceeism, "debasing of the spiritual life into worldliness."
3. Essenism, Israel mystical—a "co-mingling of Judaism with the old Oriental theosophy."
Concerning this latter section, Philo wrote a letter to a man named Hephæstion, of which the following is a portion:—
"I am sorry to find you saying that you are not likely to visit Alexandria again. This restless, wicked city can present but few attractions, I grant, to a lover of philosophic quiet. But I cannot commend the extreme to which I see so many hastening. A passion for ascetic seclusion is becoming daily more prevalent among the devout and the thoughtful, whether Jew or Gentile. Yet surely the attempt to combine contemplation and action should not be so soon abandoned. A man ought at least to have evinced some competency for the discharge of the social duties before he abandons them for the divine. First the less, then the greater.
"I have tried the life of the recluse. Solitude brings no escape from spiritual danger. If it closes some avenues of temptation, there are few in whose case it does not open more. Yet the Therapeutæ, a sect similar to the Essenes, with whom you are acquainted, number many among them whose lives are truly exemplary. Their cells are scattered about the region bordering on the farther shore of the Lake Mareotis. The members of either sex live a single and ascetic life, spending their time in fasting and contemplation, in prayer or reading. They believe themselves favoured with divine illumination—an inner light. They assemble on the Sabbath for worship, and listen to mystical discourses on the traditionary lore which they say has been handed down in secret among themselves. They also celebrate solemn dances and processions of a mystic significance by moonlight on the shore of the great mere. Sometimes, on an occasion of public rejoicing, the margin of the lake on our side will be lit with a fiery chain of illuminations, and galleys, hung with lights, row to and fro with strains of music sounding over the broad water. Then the Therapeutæ are all hidden in their little hermitages, and these sights and sounds of the world they have abandoned make them withdraw into themselves and pray.
"Their principle at least is true. The soul which is occupied with things above, and is initiated into the mysteries of the Lord, cannot but account the body evil, and even hostile. The soul of man is divine, and his highest wisdom is to become as much as possible a stranger to the body with its embarrassing appetites. God has breathed into man from heaven a portion of His own divinity. That which is divine is invisible. It may be extended, but it is incapable of separation. Consider how vast is the range of our thought over the past and the future, the heavens and the earth. This alliance with an upper world, of which we are conscious, would be impossible, were not the soul of man an indivisible portion of that divine and blessed spirit. Contemplation of the divine essence is the noblest exercise of man; it is the only means of attaining to the highest truth and virtue, and therein to behold God is the consummation of our happiness here."
Here we have the higher Buddhism, which seeks to reach the plane of spirit, an "alliance with the upper world" by the aid of solitary reverie. That Philo knew where this religion had come from is, I think, proved by another passage.
"Among the Persians there is the order of Magi who deeply investigate the works of nature for the discovery of truth, and in leisure's quiet are initiated into and expound in clearest significance the divine virtues.
"In India, too, there is the sect of the Gymnosophists, who, in addition to speculative philosophy, diligently cultivate the ethical also, and have made their life an absolute ensample of virtue.
"Palestine, moreover, and Syria are not without their harvest of virtuous excellence, which region is inhabited by no small portion of the very populous nation of the Jews. There are counted amongst them certain ones, by name Essenes, in number about four thousand, who derive their name, in my opinion, by an inaccurate trace from the term in the Greek language for holiness (Essen or Essaios—Hosios, holy), inasmuch as they have shown themselves pre-eminent by devotion to the service of God; not in the sacrifice of living animals, but rather in the determination to make their own minds fit for a holy offering." (Philo, "Every virtuous man is free.")
