These devices of the mind have a history as old as humanity. From inscrutable beginnings, in time they become recognized as makeshifts; yet they remain prone to enter new stages of confusion. The mind seeking to express the transcendental, avails itself of symbols. All religions have teemed with them, in their primitive phases scarcely distinguishing between symbol and fact; then a difference becomes evident to clearer-minded men, while perhaps at the same time others are elaborately maintaining that the symbol magically is, or brings to pass, that which it represents. Such obscuring mysticism existed not merely in confused Egypt and Brahminical India, but everywhere—in antique Greece and Rome, and then afterwards through the times of the Christian Church Fathers and the entire Middle Ages. Fact and symbol are seen constantly closing together and becoming each other like the serpent-souls in the twenty-fifth canto of Dante's Inferno.
Allegory properly speaking, which involves a conscious and sustained effort to invest concrete or material statements with more general or spiritual meaning, played an interesting rôle in epochs antecedent to the patristic and mediaeval periods. Even before Plato's time the personal myths of the gods shocked the Greek ethical intellect, which thereupon proceeded to convert them into allegories. Greek allegorical interpretation of ancient myth was apologetic to both the critical mind and the moral sense.
With Philo, the Hellenizing Jew of Alexandria, whose philosophy revolted from the literal text of Genesis, the motive for allegorical interpretation was similar. But the document before him was most unlike the Iliad and Odyssey. Genesis contained no palpably immoral stories of Jehovah to be explained away. Its account of divine creation and human beginnings merely needed to be invested with further ethical meaning. So Philo made cardinal virtues of the four rivers of Eden, and through like allegorical conceits transformed the Book of Genesis into a system of Hellenistic
exist with the new one. In a vast number of languages, such words as straight, oblique, crooked, seem always to have had both a direct and a metaphorical meaning. Moral and intellectual conceptions necessarily are expressed in phrases primarily applicable to physical phenomena.
