Chapter XIII.—Mention of the Heretic Colarbasus; Alliance Between Heresy and the Pythagorean Philosophy.
Certain, adhering partly to these, as if having propounded great conclusions, and supposed things worthy of reason, have framed enormous and endless heresies; and one of these is Colarbasus, who attempts to explain religion by measures and numbers. And others there are (who act) in like manner, whose tenets we shall explain when we commence to speak of what concerns those who give heed to Pythagorean calculation as possible; and uttering vain prophecies, hastily assume as secure the philosophy by numbers and elements. Now certain (speculators), appropriating similar reasonings from these, deceive unsophisticated individuals, alleging themselves endued with foresight; sometimes, after uttering many predictions, happening on a single fulfilment, and not abashed by many failures, but making their boast in this one. Neither shall I pass over the witless philosophy of these men; but, after explaining it, I shall prove that those who attempt to form a system of religion out of these (aforesaid elements), are disciples of a school weak and full of knavery.
