(1) SOME there be, that although they be not deceived with this error as it is set here, yet for pride and curiosity of natural wit and letterly cunning leave the common doctrine and the counsel of Holy Church. And these with all their favourers lean over much to their own knowing: and for they were never grounded in meek blind feeling and virtuous living, therefore they merit to have a false feeling, feigned and wrought by the ghostly enemy. Insomuch, that at the last they burst up and blaspheme all the saints, sacraments, statutes, and ordinances of Holy Church. Fleshly living men of the world, the which think the statutes of Holy Church over hard to be amended by, they lean to these heretics full soon and full lightly, and stalwartly maintain them, and all because them think that they lead them a softer way than is ordained of Holy Church.

(2) But if any one should say that we introduce in so doing a confusion, in disparagement of the distinction which befits God, we do not think that such a statement as this is itself sufficient to convince that it is true. For, if there is any one who has placed himself entirely in opposition to the Oracles, he will be also entirely apart from our. philosophy; and, if he has no care for the divine Wisdom of the Oracles, how shall we care for his guidance to the theological science? But, if he regards the truth of the Oracles, we also, using this canon and illumination, will advance unwaveringly to the answer, as best we can, by affirming that theology transmits some things as common, but others as distinctive; and neither is it meet to divide the common, nor to confuse the distinctive; but that following It according to our ability, we ought to rise to the Divine splendours; for, by taking thence the Divine revelations, as a most excellent canon of truth, we strive to guard the things lying there, in their native simplicity and integrity and identity--being ourselves guarded in our guard of the Oracles, and from these receiving strength to guard those who guard them.

(2) In the first place, therefore, we shall divide the genera of the proposed problems, in order that we may know the quantity and quality of them. And, in the next place, we shall show from what theologies the doubts are assumed, and according to what sciences they are investigated. For some things that are badly confused, require a certain distinction; others are conversant with the cause through which they subsist, and are apprehended; others, which we propose according to a certain contrariety, draw our decision on both sides; and some things require from us the whole development of mystic doctrines. Such, therefore, being the nature of the subjects of discussion, they are assumed from many places, and from different sciences. For some things introduce animadversions from what the wise men of the Chaldeans have delivered; others produce objections from what the prophets of the Egyptians teach; and there are some that, adhering to the theory of philosophers, make inquiries conformably to them. There are now likewise some, that from other opinions, which do not deserve to be mentioned, elicite a certain dubitation; and others originate from the common conceptions of mankind. These things, therefore, are of themselves variously disposed, and are multiformly connected with each other. Hence, through all these causes, a certain discussion is requisite for the management of them in a becoming manner.

(1) We shall, therefore, deliver to you the peculiar dogmas of the Assyrians; and also clearly develop to you our own opinions; collecting some things from the infinite writings of the ancients, but others from those particulars which were comprehended by the ancients in one treatise, and pertain to the whole knowledge of divine natures. If also you should propose any philosophic inquiry, we shall discuss it for you, according to the ancient pillars of Hermes, which Plato and Pythagoras knew before, and from thence constituted their philosophy. But such things as exhibit foreign inquiries, or which are contradictory and contentious, we shall assist mildly and aptly, or we shall demonstrate their absurdity. Such, likewise, as proceed conformably to common conceptions, we shall endeavour to discuss in a way perfectly known and clear. And things, indeed, which require the experience of divine operations to an accurate knowledge of them, we shall explain, as far as this is possible to be effected by words alone; but such as are full of intellectual theory, we shall develop with a view to the purification of the soul.
