geometry

To exhibit the nature of defection or falling away, on the part of those who conduct themselves carelessly, it will not appear out of place to employ a similitude by way of illustration. Suppose, then, the case of one who had become gradually acquainted with the art or science, say of geometry or medicine, until he had reached perfection, having trained himself for a lengthened time in its principles and practice, so as to attain a complete mastery over the art: to such an one it could never happen, that, when he lay down to sleep in the possession of his skill, he should awake in a state of ignorance. It is not our purpose to adduce or to notice here those accidents which are occasioned by any injury or weakness, for they do not apply to our present illustration. According to our point of view, then, so long as that geometer or physician continues to exercise himself in the study of his art and in the practice of its principles, the knowledge of his profession abides with him; but if he withdraw from its practice, and lay aside his habits of industry, then, by his neglect, at first a few things will gradually escape him, then by and by more and more, until in course of time everything will be forgotten, and be completely effaced from the memory. It is possible, indeed, that when he has first begun to fall away, and to yield to the corrupting influence of a negligence which is small as yet, he may, if he be aroused and return speedily to his senses, repair those losses which up to that time are only recent, and recover that knowledge which hitherto had been only slightly obliterated from his mind. Let us apply this now to the case of those who have devoted themselves to the knowledge and wisdom of God, whose learning and diligence incomparably surpass all other training; and let us contemplate, according to the form of the similitude employed, what is the acquisition of knowledge, or what is its disappearance, especially when we hear from the apostle what is said of those who are perfect, that they shall behold face to face the glory of the Lord in the revelation of His mysteries.

But now, since we are treating of the manner in which the opposing powers stir up those contests, by means of which false knowledge is introduced into the minds of men, and human souls led astray, while they imagine that they have discovered wisdom, I think it necessary to name and distinguish the wisdom of this world, and of the princes of this world, that by so doing we may discover who are the fathers of this wisdom, nay, even of these kinds of wisdom. I am of opinion, therefore, as I have stated above, that there is another wisdom of this world besides those [different kinds of] wisdom which belong to the princes of this world, by which wisdom those things seem to be understood and comprehended which belong to this world. This wisdom, however, possesses in itself no fitness for forming any opinion either respecting divine things, or the plan of the world’s government, or any other subjects of importance, or regarding the training for a good or happy life; but is such as deals wholly with the art of poetry, e.g., or that of grammar, or rhetoric, or geometry, or music, with which also, perhaps, medicine should be classed. In all these subjects we are to suppose that the wisdom of this world is included. The wisdom of the princes of this world, on the other hand, we understand to be such as the secret and occult philosophy, as they call it, of the Egyptians, and the astrology of the Chaldeans and Indians, who make profession of the knowledge of high things, and also that manifold variety of opinion which prevails among the Greeks regarding divine things. Accordingly, in the holy Scriptures we find that there are princes over individual nations; as in Daniel we read that there was a prince of the kingdom of Persia, and another prince of the kingdom of Græcia, who are clearly shown, by the nature of the passage, to be not human beings, but certain powers. In the prophecies of Ezekiel, also, the prince of Tyre is unmistakeably shown to be a kind of spiritual power. When these, then, and others of the same kind, possessing each his own wisdom, and building up his own opinions and sentiments, beheld our Lord and Saviour professing and declaring that He had for this purpose come into the world, that all the opinions of science, falsely so called, might be destroyed, not knowing what was concealed within Him, they forthwith laid a snare for Him: for “the kings of the earth set themselves, and the rulers assembled together, against the Lord and His Christ.” But their snares being discovered, and the plans which they had attempted to carry out being made manifest when they crucified the Lord of glory, therefore the apostle says, “We speak wisdom among them that are perfect, but not the wisdom of this world, nor of the princes of this world, who are brought to nought, which none of the princes of this world knew: for had they known it, they would not have crucified the Lord of glory.”

We must, indeed, endeavour to ascertain whether that wisdom of the princes of this world, with which they endeavour to imbue men, is introduced into their minds by the opposing powers, with the purpose of ensnaring and injuring them, or only for the purpose of deceiving them, i.e. not with the object of doing any hurt to man; but, as these princes of this world esteem such opinions to be true, they desire to impart to others what they themselves believe to be the truth: and this is the view which I am inclined to adopt. For as, to take an illustration, certain Greek authors, or the leaders of some heretical sect, after having imbibed an error in doctrine instead of the truth, and having come to the conclusion in their own minds that such is the truth, proceed, in the next place, to endeavour to persuade others of the correctness of their opinions; so, in like manner, are we to suppose is the procedure of the princes of this world, in which to certain spiritual powers has been assigned the rule over certain nations, and who are termed on that account the princes of this world. There are besides, in addition to these princes, certain special energies of this world, i.e. spiritual powers, which bring about certain effects, which they have themselves, in virtue of their freedom of will, chosen to produce, and to these belong those princes who practise the wisdom of this world: there being, for example, a peculiar energy and power, which is the inspirer of poetry; another, of geometry; and so a separate power, to remind us of each of the arts and professions of this kind. Lastly, many Greek writers have been of opinion that the art of poetry cannot exist without madness; whence also it is several times related in their histories, that those whom they call poets were suddenly filled with a kind of spirit of madness. And what are we to say also of those whom they call diviners, from whom, by the working of those demons who have the mastery over them, answers are given in carefully constructed verses? Those persons, too, whom they term Magi or Malevolent, frequently, by invoking demons over boys of tender years, have made them repeat poetical compositions which were the admiration and amazement of all. Now these effects we are to suppose are brought about in the following manner: As holy and immaculate souls, after devoting themselves to God with all affection and purity, and after preserving themselves free from all contagion of evil spirits, and after being purified by lengthened abstinence, and imbued with holy and religious training, assume by this means a portion of divinity, and earn the grace of prophecy, and other divine gifts; so also are we to suppose that those who place themselves in the way of the opposing powers, i.e. who purposely admire and adopt their manner of life and habits, receive their inspiration, and become partakers of their wisdom and doctrine. And the result of this is, that they are filled with the working of those spirits to whose service they have subjected themselves. 4, With respect to those, indeed, who teach differently regarding Christ from what the rule of Scripture allows, it is no idle task to ascertain whether it is from a treacherous purpose that these opposing powers, in their struggles to prevent a belief in Christ, have devised certain fabulous and impious doctrines; or whether, on hearing the word of Christ, and not being able to cast it forth from the secrecy of their conscience, nor yet to retain it pure and holy, they have, by means of vessels that were convenient to their use, and, so to speak, through their prophets, introduced various errors contrary to the rule of Christian truth. Now we are to suppose rather that apostate and refugee powers, which have departed from God out of the very wickedness of their mind and will, or from envy of those for whom there is prepared (on their becoming acquainted with the truth) an ascent to the same rank, whence they themselves had fallen, did, in order to prevent any progress of that kind, invent these errors and delusions of false doctrine. It is then clearly established, by many proofs, that while the soul of man exists in this body, it may admit different energies, i.e. operations, from a diversity of good and evil spirits. Now, of wicked spirits there is a twofold mode of operation: i.e. when they either take complete and entire possession of the mind, so as to allow their captives the power neither of understanding nor feeling; as, for instance, is the case with those commonly called possessed, whom we see to be deprived of reason, and insane (such as those were who are related in the Gospel to have been cured by the Saviour); or when by their wicked suggestions they deprave a sentient and intelligent soul with thoughts of various kinds, persuading it to evil, of which Judas is an illustration, who was induced at the suggestion of the devil to commit the crime of treason, according to the declaration of Scripture, that “the devil had already put it into the heart of Judas Iscariot to betray Him.” But a man receives the energy, i.e. the working, of a good spirit, when he is stirred and incited to good, and is inspired to heavenly or divine things; as the holy angels and God Himself wrought in the prophets, arousing and exhorting them by their holy suggestions to a better course of life, yet so, indeed, that it remained within the will and judgment of the individual, either to be willing or unwilling to follow the call to divine and heavenly things. And from this manifest distinction, it is seen how the soul is moved by the presence of a better spirit, i.e. if it encounter no perturbation or alienation of mind whatever from the impending inspiration, nor lose the free control of its will; as, for instance, is the case with all, whether prophets or apostles, who ministered to the divine responses without any perturbation of mind. Now, that by the suggestions of a good spirit the memory of man is aroused to the recollection of better things, we have already shown by previous instances, when we mentioned the cases of Mordecai and Artaxerxes.

Greeting in God, my most excellent sir, and venerable son Gregory, from Origen. A natural readiness of comprehension, as you well know, may, if practice be added, contribute somewhat to the contingent end, if I may so call it, of that which any one wishes to practise. Thus, your natural good parts might make of you a finished Roman lawyer or a Greek philosopher, so to speak, of one of the schools in high reputation. But I am anxious that you should devote all the strength of your natural good parts to Christianity for your end; and in order to this, I wish to ask you to extract from the philosophy of the Greeks what may serve as a course of study or a preparation for Christianity, and from geometry and astronomy what will serve to explain the sacred Scriptures, in order that all that the sons of the philosophers are wont to say about geometry and music, grammar, rhetoric, and astronomy, as fellow-helpers to philosophy, we may say about philosophy itself, in relation to Christianity.
