But the too great dependence upon physical facts led to a growth of materialism and a decadence of spirituality and faith. At the time of Aristotle, this was the prevailing tendency of thought. And though the Delphic commandment was not as yet completely eliminated from Grecian thought; and some philosophers still held that “in order to know what man _is_, we ought to know what man _was_”— still materialism had already begun to gnaw at the root of faith. The Mysteries themselves had degenerated in a very great degree into mere priestly speculations and religious fraud. Few were the true adepts and initiates, the heirs and descendants of those who had been dispersed by the conquering swords of various invaders of Old Egypt. The time predicted by the great Hermes in his dialogue with Æsculapius {16} had indeed come; the time when impious foreigners would accuse Egypt of adoring monsters, and naught but the letters engraved in stone upon her monuments would survive—enigmas incredible to posterity. Their sacred scribes and hierophants were wanderers upon the face of the earth. Obliged from fear of a profanation of the sacred mysteries to seek refuge among the Hermetic fraternities—known later as the _Essenes_—their esoteric knowledge was buried deeper than ever. The triumphant brand of Aristotle’s pupil swept away from his path of conquest every vestige of a once pure religion, and Aristotle himself, the type and child of his epoch, though instructed in the secret science of the Egyptians, knew but little of this crowning result of millenniums of esoteric studies. As well as those who lived in the days of the Psammetics, our present-day philosophers “lift the Veil of Isis”—for Isis is but the symbol of nature. But, they see only her physical forms. The soul within escapes their view; and the Divine Mother has no answer for them. There are anatomists, who, uncovering to sight no indwelling spirit under the layers of muscles, the net-work of nerves, or the cineritious matter, which they lift with the point of the scalpel, assert that man has no soul. Such are as purblind in sophistry as the student, who, confining his research to the cold letter of the Kabala, dares say it has no vivifying spirit. To see the true man who once inhabited the subject which lies before him, on the dissecting table, the surgeon must use other eyes than those of his body. So, the glorious truth covered up in the hieratic writings of the ancient papyri can be revealed only to him who possesses the faculty of intuition—which, if we call reason the eye of the mind, may be defined as the eye of the soul.
