The distinction of names and things also in the Scriptures themselves produces great light in men’s souls. For it is necessary to understand expressions which signify several things, and several expressions when they signify one thing. The result of which is accurate answering. But it is necessary to avoid the great futility which occupies itself in irrelevant matters; since the Gnostic avails himself of branches of learning as auxiliary preparatory exercises, in order to the accurate communication of the truth, as far as attainable and with as little distraction as possible, and for defence against reasonings that plot for the extinction of the truth. He will not then be deficient in what contributes to proficiency in the curriculum of studies and the Hellenic philosophy; but not principally, but necessarily, secondarily, and on account of circumstances. For what those labouring in heresies use wickedly, the Gnostic will use rightly.
