(12) These three, of course, are not the only marks which differentiate them from common people, but the only ones that come within our cognizance. Just as no one knows the real nature of God but God Himself, so no one knows the real nature of a prophet but a prophet. Nor is this to be wondered at, as in everyday matters we see that it is impossible to explain the charm of poetry to one whose ear is insusceptible of cadence and rhythm, or the glories of colour to one who is stone-blind. Besides mere incapacity, there are other hindrances to the attainment of spiritual truth. One of these is externally acquired knowledge. To use a figure, the heart may be represented as a well, and the five senses as five streams which are continually conveying water to it. In order to find out the real contents of the heart these streams must be stopped for a time, at any rate, and the refuse they have brought with them must be cleared out of the well. In other words, if we are to arrive at pure spiritual truth, we must put away, for the time knowledge which has been acquired by external processes and which too often hardens into dogmatic prejudice.

(2) But if any one think well to accept the sacred compositions as of things simple and unknown in their own nature, and beyond our contemplation, but thinks the imagery of the holy minds in the Oracles is incongruous, and that all this is, so to speak, a rude scenic representation of the angelic names; and further says that the theologians ought, when they have come to the bodily representation of creatures altogether without body, to represent and display them by appropriate and, as far as possible, cognate figures, taken, at any rate, from our most honoured and immaterial and exalted beings, and ought not to clothe the heavenly and Godlike simple essences with the many forms of the lowest creatures to be found on the earth (for the one would perhaps be more adapted to our instruction, and would not degrade the celestial explanations to incongruous dissimilitudes; but the other both does violence without authority to the Divine powers, and likewise leads astray our minds, through dwelling upon these irreverent descriptions); and perhaps he will also think that the super-heavenly places are filled with certain herds of lions, and troops of horses, and bellowing songs of praise, and flocks of birds, and other living creatures, and material and less honourable things, and whatever else the similitudes of the Oracles, in every respect dissimilar, describe, for a so-called explanation, but which verge towards the absurd, and pernicious, and impassioned; now, in my opinion, the investigation of the truth demonstrates the most sacred wisdom of the Oracles, in the descriptions of the Heavenly Minds, taking forethought, as that wisdom does, wholly for each, so as neither, as one may say, to do violence to the Divine Powers, nor at the same time to enthral us in the grovelling passions of the debased imagery. For any one might say that the cause why forms are naturally attributed to the formless, and shapes to the shapeless, is not alone our capacity which is unable immediately to elevate itself to the intelligible contemplations, and that it needs appropriate and cognate instructions which present images, suitable to us, of the formless and supernatural objects of contemplation; but further, that it is most agreeable to the revealing Oracles to conceal, through mystical and sacred enigmas, and to keep the holy and secret truth respecting the supermundane minds inaccessible to the multitude. For it is not every one that is holy, nor, as the Oracles affirm, does knowledge belong to all.

(75) This is the burden of your parables and presages, This the purport of your awe-inspiring stories." The prophets replied, "Our evil presages Suppose you are sleeping in a place of danger, And serpents are drawing near to bite your heads, A kind friend will inform you of your danger, Saying, 'Jump up, lest the serpent devour you.' You reply, 'Why do you utter evil presages?' He answers, 'What presage? Up, and see for yourself! By means of this evil presage I rouse you,

(3) If, also, the power of the Gods proceeds in premanifestation as far as to things inanimate, such as pebble stones, rods, pieces of wood, stones, corn, or wheat, this very thing is most admirable in the presignification of divine prophesy; because it imparts soul to things inanimate, motion to things immoveable, and makes all things to be clear and known, to partake of reason, and to be defined by the measures of intellection, though possessing no portion of reason from themselves. Another divine miracle also divinity appears to me to exhibit through signs in these things. For, as he sometimes makes some stupid man to speak wisely, through which it becomes manifest to every one, that this is not a certain human but a divine work; thus, also, he reveals through things which are deprived of knowledge, conceptions which precede all knowledge. And, at the same time, he declares to men that the signs which are exhibited are worthy of belief, and that they are superior to nature, from which he is exempt. Thus he makes things to be known which are naturally unknown, and things which are without knowledge gnostic.
