(15) And Wisdom being manifold, pervading the whole world, and all human affairs, varies its appellation in each case. When it applies itself to first causes, it is called Understanding (nohsis). When, however, it confirms this by demonstrative reasoning, it is termed Knowledge, and Wisdom, and Science. When it is occupied in what pertains to piety, and receives without speculation the primal Word in consequence of the maintenance of the operation in it, it is called Faith. In the sphere of things of sense, establishing that which appears as being truest, it is Right Opinion. In operations, again, performed by skill of hand, it is Art But when, on the other hand, without the study of primary causes, by the observation of similarities, and by transposition, it makes any attempt or combination, it is called Experiment. But belonging to it, and supreme and essential, is the Holy Spirit, which above all he who, in consequence of [divine] guidance, has believed, receives after strong faith.

(7) Now we know that neither things which are clear are made subjects of investigation, such as if it is day, while it is day; nor things unknown, and never destined to become clear, as whether the stars are even or odd in number; nor things convertible; and those are so which can be said equally by those who take the opposite side, as if what is in the womb is a living creature or not. A fourth mode is, when, from either side of those, there is advanced an unanswerable and irrefragable argument. If, then, the ground of inquiry, according to all of these modes, is removed, faith is established. For we advance to them the unanswerable consideration, that it is God who speaks and comes to our help in writing, respecting each one of the points regarding which I investigate. Who, then, is so impious as to disbelieve God, and to demand proofs from God as from men? Again, some questions demand the evidence of the senses, as if one were to ask whether the fire be warm, or the snow white; and some admonition and rebuke, as the question if you ought to honour your parents.

(7) But this much is enough, since it is impossible for anyone to dispute the nature of the words I have just spoken about the blessed, imperishable, true God. Now, if anyone wants to believe the words set down (here), let him go from what is hidden to the end of what is visible, and this Thought will instruct him how faith in those things that are not visible was found in what is visible. This is a principle of knowledge.

(21) But if thou lockest up thy soul within thy body, and dost debase it, saying: I nothing know; I nothing can; I fear the sea; I cannot scale the sky; I know not who I was, who I shall be - what is there [then] between [thy] God and thee? For thou canst know naught of things beautiful and good so long as thou dost love thy body and art bad. The greatest bad there is, is not to know God's Good; but to be able to know [Good], and will, and hope, is a Straight Way, the Good's own [Path], both leading there and easy. If thou but settest thy foot thereon, 'twill meet thee everywhere, 'twill everywhere be seen, both where and when thou dost expect it not - waking, sleeping, sailing, journeying, by night, by day, speaking, [and] saying naught. For there is naught that is not image of the Good.

(2) Wherefore it alone conducts to the true wisdom, which is the divine power which deals with the knowledge of entities as entities, which grasps what is perfect, and is freed from all passion; not without the Saviour, who withdraws, by the divine word, the gloom of ignorance arising from evil training, which had overspread the eye of the soul, and bestows the best of gifts,- "That we might well know or God or man."

(4) And again, "According to thy faith let it be to thee." And one is cured, receiving healing by faith; and the dead is raised up in consequence of the power of one believing that he would be raised. The demonstration, however, which rests on opinion is human, and is the result of rhetorical arguments or dialectic syllogisms. For the highest demonstration, to which we have alluded, produces intelligent faith by the adducing and opening up of the Scrip tures to the souls of those who desire to learn; the result of which is knowledge (gnosis). For if what is adduced in order to prove the point at issue is assumed to be true, as being divine and prophetic, manifestly the conclusion arrived at by inference from it will consequently he inferred truly; and the legitimate result of the demonstration will be knowledge. When, then, the memorial of the celestial and divine food was commanded to be consecrated in the golden pot, it was said, "The omer was the tenth of the three measures." For in ourselves, by the three measures are indicated three criteria; sensation of objects of sense, speech, - of spoken names and words, and the mind, - of intellectual objects.

(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.

(533) the soul, which is literally buried in an outlandish slough, is by her gentle aid lifted upwards; and she uses as handmaids and helpers in the work of conversion, the sciences which we have been discussing. Custom terms them sciences, but they ought to have some other name, implying greater clearness than opinion and less clearness than science: and this, in our previous sketch, was called understanding. But why should we dispute about names when we have realities of such importance to consider? Why indeed, he said, when any name will do which expresses the thought of the mind with clearness? At any rate, we are satisfied, as before, to have four divisions; two for intellect and two for opinion, and to call the first division science, the second understanding, the third belief, and the fourth perception of shadows, opinion being concerned with becoming, and intellect with being; and so to make a proportion:— As being is to becoming, so is pure intellect to opinion. And as intellect is to opinion, so is science to belief, and understanding to the perception of shadows. But let us defer the further correlation and subdivision of the subjects of opinion and of intellect, for it will be a long enquiry, many times longer than this has been.

(6) 'That which cannot be seen, nor seized, which has no family and no caste, no eyes nor ears, no hands nor feet, the eternal, the omnipresent (all-pervading), infinitesimal, that which is imperishable, that it is which the wise regard as the source of all beings.'

(9) ’Tis mind that all things sees and hears;

What else exists is deaf and blind.

But the precept which is next to this in efficacy is that which exhorts to be beyond measure studious of purifying the intellect, and by various methods adapting it through mathematical orgies to receive something divinely beneficial, so as neither to fear a separation from body, nor, when led to incorporeal natures, to be forced to turn away the eyes, through their most refulgent splendor, nor to be converted to those passions which nail and fasten the soul to the body. And, in short, which urges the soul to be untamed by all those passions which are the progeny of the realms of generation, and which draw it to an inferior condition of being. For the exercise and ascent through all these, is the study of the most perfect fortitude. And such are the instances adduced by us of the fortitude of Pythagoras, and the Pythagoreans.

(9) But God is not, as some suppose, beyond the reach of sense-and-thought. It is through superstition men thus impiously speak. For all the things that are, Asclepius, all are in God, are brought by God to be, and do depend on Him - both things that act through bodies, and things that through soul-substance make [other things] to move, and things that make things live by means of spirit, and things that take unto themselves the things that are worn out. And rightly so; nay, I would rather say, He doth not have these things; but I speak forth the truth, He is them all Himself. He doth not get them from without, but gives them out [from Him]. This is God's sense-and-thought, ever to move all things. And never time shall be when e'en a whit of things that are shall cease; and when I say "a whit of things that are", I mean a whit of God. For thigs that are, God hath; nor aught [is there] without Him, nor [is] He without aught.

(4) Whence life is full of tribunals and councils; and, in fine, of selection in what is said to be good and bad; which are the signs of a mind in doubt, and halting through feebleness on account of conflicting matters. And there are libraries full of books,' and compilations and treatises of those who differ in dogmas, and are confident that they themselves know the truth that there is in things.

(1) But since they will believe neither in what is good justly nor in knowledge unto salvation, we ourselves reckoning what they claim as belonging to us, because all things are God's; and especially since what is good proceeded from us to the Greeks, let us handle those things as they are capable of hearing. For intelligence or rectitude this great crowd estimates not by truth, but by what they are delighted with. And they will be pleased not more with other things than with what is like themselves. For he who is still blind and dumb, not having understanding, or the undazzled and keen vision of the contemplative soul, which the Saviour confers, like the uninitiated at the mysteries, or the unmusical at dances, not being yet pure and worthy of the pure truth, but still discordant and disordered and material, must stand outside of the divine choir.

(21) But, as appears, we incline to ideas founded on opinion, though they be contrary, rather than to the truth. For it is austere and grave. Now, since there are three states of the soul - ignorance, opinion, knowledge - those who are in ignorance are the Gentiles, those in knowledge, the true Church, and those in opinion, the Heretics. Nothing, then, can be more clearly seen than those, who know, making affirmations about what they know, and the others respecting what they hold on the strength of opinion, as far as respects affirmation without proof.

(6) This is, O Tat, the Gnosis of the Mind, Vision of things Divine; God-knowledge is it, for the Cup is God's. T: Father, I, too, would be baptized. H: Unless thou first shall hate thy Body, son, thou canst not love thy Self. But if thou lov'st thy Self thou shalt have Mind, and having Mind thou shalt share in the Gnosis. T: Father, what dost thou mean? H: It is not possible, my son, to give thyself to both - I mean to things that perish and to things divine. For seeing that existing things are twain, Body and Bodiless, in which the perishing and the divine are understood, the man who hath the will to choose is left the choice of one or the other; for it can never be the twain should meet. And in those souls to whom the choice is left, the waning of the one causes the other's growth to show itself.

(4) On this same manner ghostly it fareth within our ghostly wits, when we travail about the knowing of God Himself. For have a man never so much ghostly understanding in knowing of all made ghostly things, yet may he never by the work of his understanding come to the knowing of an unmade ghostly thing: the which is nought but God. But by the failing it may: for why, that thing that it faileth in is nothing else but only God. And therefore it was that Saint Denis said, the most goodly knowing of God is that, the which is known by unknowing. And truly, whoso will look in Denis’ books, he shall find that his words will clearly affirm all that I have said or shall say, from the beginning of this treatise to the end. On otherwise than thus, list me not cite him, nor none other doctor, for me at this time. For sometime, men thought it meekness to say nought of their own heads, unless they affirmed it by Scripture and doctors’ words: and now it is turned into curiosity, and shewing of cunning. To thee it needeth not, and therefore I do it not. For whoso hath ears, let him hear, and whoso is stirred for to trow, let him trow: for else, shall they not.

(511) they start from hypotheses and do not ascend to a principle, those who contemplate them appear to you not to exercise the higher reason upon them, although when a first principle is added to them they are cognizable by the higher reason. And the habit which is concerned with geometry and the cognate sciences I suppose that you would term understanding and not reason, as being intermediate between opinion and reason. You have quite conceived my meaning, I said; and now, corresponding to these four divisions, let there be four faculties in the soul—reason answering to the highest, understanding to the second, faith (or conviction) to the third, and perception of shadows to the last—and let there be a scale of them, and let us suppose that the several faculties have clearness in the same degree that their objects have truth. I understand, he replied, and give my assent, and accept your arrangement.

(5) But there is that species of knowledge which is characteristic of the herald, and that which is, as it were, characteristic of a messenger, and it is serviceable in whatever way it operates, both by the hand and tongue. "For he that soweth to the Spirit, shall of the Spirit reap life everlasting. And let us not be weary in well-doing." On him who by Divine Providence meets in with it, it confers the very highest advantages, - the beginning of faith, readiness for adopting a right mode of life, the impulse towards the truth, a movement of inquiry, a trace of knowledge; in a word, it gives the means of salvation. And those who have been rightly reared in the words of truth, and received provision for eternal life, wing their way to heaven. Most admirably, therefore, the apostle says, "In everything approving ourselves as the servants of God; as poor, and yet making many rich; as having nothing, yet possessing all things.

(1) AND therefore the sharp stirring of thine understanding, that will always press upon thee when thou settest thee to this work, behoveth always be borne down; and but thou bear him down, he will bear thee down. Insomuch, that when thou weenest best to abide in this darkness, and that nought is in thy mind but only God; an thou look truly thou shalt find thy mind not occupied in this darkness, but in a clear beholding of some thing beneath God. And if it thus be, surely then is that thing above thee for the time, and betwixt thee and thy God. And therefore purpose thee to put down such clear beholdings, be they never so holy nor so likely. For one thing I tell thee, it is more profitable to the health of thy soul, more worthy in itself, and more pleasing to God and to all the saints and angels in heaven—yea, and more helpful to all thy friends, bodily and ghostly, quick and dead—such a blind stirring of love unto God for Himself, and such a privy pressing upon this cloud of unknowing, and better thee were for to have it and for to feel it in thine affection ghostly, than it is for to have the eyes of thy soul opened in contemplation or beholding of all the angels or saints in heaven, or in hearing of all the mirth and the melody that is amongst them in bliss.

(69) Reason knows nothing at all of God; and if it be not possible to attain further from the Gift of God, do not descend down into the Deep, but in Singleness of Heart stay on the Article; it will not endanger thy Happiness. God looks only upon the Will of the Heart. Thou must not search so deep into every Thing, if it be not given thee, as it is to this Pen; this Pen writes in the Council of God (that which the Hand knows not, and scarce understands the least Spark of it) and yet very deeply, as thou seest, that the Things to come are shown in a very difficult Depth, which God alone will discover in due Time, which is unknown to us.
