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.”[674] 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.”[675] 3. We must, indeed, endeavour to ascertain whether that wisdom[676] 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[677] 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;[678] whence also it is several times related in their histories, that those whom they call poets[679] were suddenly filled with a kind of spirit of madness. And what are we to say also of those whom they call diviners,[680] 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
