(17) The first species, then, of the different kinds of questions, which are three, has been exhibited - I mean that, in which the essence being known, some one of its powers or properties is unknown. The second variety of propositions was that in which we all know the powers and properties, but do not know the essence; as, for example, in what part of the body is the principal faculty of the soul.

(1) For every question is solved from pre-existing knowledge. And the knowledge pre-existing of each object of investigation is sometimes merely of the essence, while its functions are unknown (as of stones, and plants, and animals, of whose operations we are ignorant), or [the knowledge] of the properties, or powers, or (so to speak) of the qualities inherent in the objects. And sometimes we may know some one or more of those powers or properties, - as, for example, the desires and affections of the soul, - and be ignorant of the essence, and make it the object of investigation. But in many instances, our understanding having assumed all these, the question is, in which of the essences do they thus inhere; for it is after forming conceptions of both - that is, both of essence and operation - in our mind, that we proceed to the question. And there are also some objects, whose operations, along with their essences, we know, but are ignorant of their modifications.

(3) Of things stated, some are stated without connection; as, for example, "man" and "runs," and whatever does not complete a sentence, which is either true or false. And of things stated in connection, some point out "essence," some "quality," some "quantity," some "relation,'' some "where," some "when," some "position," some "possession," some "action," some "suffering," which we call the elements of material things after the first principles. For these are capable of being contemplated by reason.

(3) "And that mystery of the Ineffable is moreover also a one and only word, which existeth in the speech of the Ineffable, and it is the economy of the solution of all the words which I have spoken unto you. "And he who will receive the one and only word of that mystery which I shall now say unto you, and all its types and all its figures, and the manner of accomplishing its mystery,--for ye are perfect and all-perfect and ye will accomplish the whole gnosis of that mystery with its whole economy, for unto you all mysteries are entrusted,--hearken, therefore, now, that I may tell you that mystery, which is [ . . .?].

(2) Now, not only demonstration and belief and knowledge, but foreknowledge also, are used in a twofold manner. There is that which is scientific and certain, and that which is merely based on hope.

(18) In all questions, then, there is something which is previously known, - that which being self-evident is believed without demonstration; which must be made the starting point in their investigation, and the criterion of apparent results.

(44) I am not known, but I am one who knoweth thee

(1) As, then, Knowledge (episthmh) is an intellectual state, from which results the act of knowing, and becomes apprehension irrefragable by reason; so also ignorance is a receding impression, which can be dislodged by reason. And that which is overthrown as well as that which is elaborated by reason, is in our power. Akin to Knowledge is experience, cognition (eidhsis), Comprehension (sunesis), perception, and Science. Cognition (eidhsis) is the knowledge of universals by species; and Experience is comprehensive knowledge, which investigates the nature of each thing. Perception (nohsis) is the knowledge of intellectual objects; and Comprehension (sunesis) is the knolwedge of what is compared, or a comparison that cannot be annulled, or the faculty of comparing the objects with which Judgment and Knowledge are occupied, both of one and each and all that goes to make up one reason. And Science (gnwsis) is the knowledge of the thing in itself, or the knowledge which harmonizes with what takes place. Truth is the knowledge of the true; and the mental habit of truth is the knowledge of the things which are true. Now knowledge is constituted by the reason, and cannot be overthrown by another reason. What we do not, we do not either from not being able, or not being willing - or both. Accordingly we don't fly, since we neither can nor wish; we do not swim at present, for example, since we can indeed, but do not choose; and we are not as the Lord, since we wish, but cannot be: "for no disciple is above his master, and it is sufficient if we be as the master:" not m essence (for it is impossible for that, which is by adoption, to be equal in substance to that, which is by nature); but [we are as Him] only in our having been made immortal, and our being conversant with the contemplation of realities, and beholding the Father through what belongs to Him.

(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.

(23) One, therefore, will give the definition of whatever he possesses the knowledge of; as one can by no means be acquainted with that which he cannot embrace and define in speech. And in consequence of ignorance of the definition, the result is, that many disputes and deceptions arise. For if he that knows the thing has the knowledge of it in his mind, and can explain by words what he conceives; and if the explanation of the thought is definition; then he that knows the thing must of necessity be able also to give the definition.

(5) And if this position is true, that we do not know what is true, then absolutely nothing is allowed to be true by it. But if he will say that even this is questionable, whether we know what is true; by this very statement he grants that truth is knowable, in the very act of appearing to establish the doubt respecting it.

(3) 'That by which we know form, taste, smell, sounds, and loving touches, by that also we know what exists besides. This is that (which thou hast asked for).'

(3) Then it is to be inquired whether the proposition belongs to those points, which are considered in relation to others, or is taken by itself. Further, If it is, what it is, what happens to it; or thus, also, if it is, what it is, why it is. And to the consideration of these points, the knowledge of Particulars and Universals, and the Antecedents and the Differences, and their divisions, contribute.

(3) Now we assert that knowledge (gnosis) differs from the wisdom (sofia), which is the result of teaching. For as far as anything is knowledge, so far is it certainly wisdom; but in as far as aught is wisdom, it is not certainly knowledge. For the term wisdom appears only in the knowledge of the uttered word.

(2) The names are reduced by grammar into the twenty-four general elements; for the elements must be determined. For of Particulars there is no scientific knowledge, seeing they are infinite. But it is the property of science to rest on general and defined principles. Whence also Particulars are resolved into Universals. And philosophic research is occupied with Conceptions and Real subjects. But since of these the Particulars are infinite, some elements have been found, under which every subject of investigation is brought; and if it be shown to enter into any one or more of the elements, we prove it to exist; but if it escape them all, that it does not exist.

(4) 2. “Man was generated by far the wisest of all [terrestrial] animals. For he is able to contemplate the things which exist, and to obtain from all things science and wisdom. To which also it may be added, that divinity has engraved and exhibited in him the system of universal reason, in which all the forms of things in existence are distributed, and the significations of nouns and verbs. For a place is assigned for the sounds of the voice, viz. the pharynx, the mouth, and the nostrils. But as man was generated the instrument of the sounds, through which nouns and verbs are signified, so likewise of the conceptions which are beheld in the things that have an existence. And this appears to me to be the work of wisdom, for the accomplishment of which man was generated and constituted, and received organs and powers from divinity.

(13) Thus briefly have been set forth the Field and also knowledge and the object of knowledge. My devotee who understands this becomes worthy of My state.

(3) 1. The knowledge of self. 2. The knowledge of God. 3. The knowledge of this world as it really is. 4. The knowledge of the next world as it really is. We shall now proceed to expound these four constituents in order.

(7) If this one, who is unknowable in his nature, to whom pertain all the greatnesses which I already mentioned - if, out of the abundance of his sweetness, he wishes to grant knowledge, so that he might be known, he has the ability to do so. He has his Power, which is his will. Now, however, in silence he himself holds back, he who is the great one, who is the cause of bringing the Totalities into their eternal being.

(13) If, then, the love of knowledge produces immortality, and leads the kingly man near to God the King, knowledge ought to be sought till it is found. Now seeking is an effort at grasping, and finds the subject by means of certain signs. And discovery is the end and cessation of inquiry, which has now its object in its gasp. And this is knowledge. And this discovery, properly so called, is knowledge, which is the apprehension of the object of search. And they say that a proof is either the antecedent, or the coincident, or the consequent. The discovery, then, of what is sought respecting God, is the teaching through the Son; and the proof of our Saviour being the very Son of God is the prophecies which preceded His coming, announcing Him; and the testimonies regarding Him which attended His birth in the world; in addition, His powers proclaimed and openly shown after His ascension.
