The Refutation of All Heresies

Since, therefore, in the six books preceding this, we have explained previous (heretical opinions), it now seems proper not to be silent respecting the (doctrines) of Basilides, which are the tenets of Aristotle the Stagyrite, not (those) of Christ. But even though on a former occasion the opinions propounded by Aristotle have been elucidated, we shall not even now scruple to set them down beforehand in a sort of synopsis, for the purpose of enabling my readers, by means of a nearer comparison of the two systems, to perceive with facility that the doctrines advanced by Basilides are (in reality) the clever quibbles of Aristotle.
