(23) Two fundamental forms of ignorance were recognized by the Platonists: simple ignorance and complex ignorance. Simple ignorance is merely lack of knowledge and is common to all creatures existing posterior to the First Cause, which alone has perfection of knowledge. Simple ignorance is an ever-active agent, urging the soul onward to the acquisition of knowledge. From this virginal state of unawareness grows the desire to become aware with its resultant improvement in the mental condition. The human intellect is ever surrounded by forms of existence beyond the estimation of its partly developed faculties. In this realm of objects not understood is a never-failing source of mental stimuli. Thus wisdom eventually results from the effort to cope rationally with the problem of the unknown.

(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.

(4) you knowledge, you depart in ignorance of God, this ignorance also is an essential attribute, and will abide as darkness of soul and the seed of misery. Therefore the Koran says, "He who is blind in this life will be blind in the next life, and astray from the path."

(44) It is the manner of life which shows up those who know the commandments; for as a man's word is, so is his life. The tree is known by its fruit, not by its blossom and leaves. Knowledge, then, comes from the fruit and from behaviour, not from talk and from blossom. We say that knowledge is not mere talk, but a certain divine knowledge, that light which is kindled in the soul as a result of obedience to the commandments, and which reveals all that is in a state of becoming, enables man to know himself and teaches him to become possessed of God. What the eye is in the body, knowledge is in the mind. Let them not call bondage to pleasure freedom, as if bitterness were sweet. We have learnt to recognize as freedom that which the Lord alone confers on us when he liberates us from lusts and desires and the other passions. "He who says, I know the Lord, and does not keep his commandments, is a liar and the truth is not in him," says John.

(5) The darkness of ignorance is: holding that which is unenduring, impure, full of pain, not the Soul, to be eternal, pure, full of joy, the Soul.

(4) The knowledge of ignorance is, then, the first lesson in walking according to the Word. An ignorant man has sought, and having sought, he finds the teacher; and finding has believed, and believing has hoped; and henceforward having loved, is assimilated to what was loved - en-deavouring to be what he first loved. Such is the method Socrates shows Alcibiades, who thus questions: "Do you not think that I shall know about what is right otherwise?" "Yes, if you have found out." "But you don't think I have found out?" "Certainly, if you have sought."

(1) DARKNESS becomes invisible by light, and specially by much light. Varied knowledge (αἰ γνώσεις), and especially much varied knowledge, makes the Agnosia to vanish. Take this in a superlative, but not in a defective sense, and reply with superlative truth, that the Agnosia, respecting God, escapes those who possess existing light, and knowledge of things being; and His pre-eminent darkness is both concealed by every light, and is hidden from every knowledge. And, if any one, having seen God, understood what he saw, he did not see Him, but some of His creatures that are existing and known. But He Himself, highly established above mind, and above essence, by the very fact of His being wholly unknown, and not being, both is super-essentially, and is known above mind. And the all-perfect Agnosia, in its superior sense, is a knowledge of Him, Who is above all known things.

(30) Philosophy reveals to man his kinship with the All. It shows him that he is a brother to the suns which dot the firmament; it lifts him from a taxpayer on a whirling atom to a citizen of Cosmos. It teaches him that while physically bound to earth (of which his blood and bones are part), there is nevertheless within him a spiritual power, a diviner Self, through which he is one with the symphony of the Whole. Ignorance of ignorance, then, is that self-satisfied state of unawareness in which man, knowing nothing outside the limited area of his physical senses, bumptiously declares there is nothing more to know! He who knows no life save the physical is merely ignorant; but he who declares physical life to be all-important and elevates it to the position of supreme reality--such a one is ignorant of his own ignorance.

(11) They who imagine truth in untruth, and see untruth in truth, never arrive at truth, but follow vain desires.

(26) In addition to the simple ignorance which is the most potent factor in mental growth there exists another, which is of a far more dangerous and subtle type. This second form, called twofold or complex ignorance, may be briefly defined as ignorance of ignorance. Worshiping the sun, moon, and stars, and offering sacrifices to the winds, the primitive savage sought with crude fetishes to propitiate his unknown gods. He dwelt in a world filled with wonders which he did not understand. Now great cities stand where once roamed the Crookboned men. Humanity no longer regards itself as primitive or aboriginal. The spirit of wonder and awe has been succeeded by one of sophistication. Today man worships his own accomplishments, and either relegates the immensities of time and space to the background of his consciousness or disregards them entirely.

(13) Constancy in Self-knowledge, perception of the end of the knowledge of truth. This is declared to be knowledge, and what is opposed to it is ignorance.

(1) For he who hopes, as he who believes, sees intellectual objects and future things with the mind. If, then, we affirm that aught is just, and affirm it to be good, and we also say that truth is something, yet we have never seen any of such objects with our eyes, but with our mind alone. Now the Word of God says, "I am the truth." The Word is then to be contemplated by the mind. "Do you aver," it was said, "that there are any true philosophers?" "Yes," said I, "those who love to contemplate the truth." In the Phaedrus also, Plato, speaking of the truth, shows it as an idea. Now an idea is a conception of God; and this the barbarians have termed the Word of God. The words are as follow: "For one must then dare to speak the truth, especially in speaking of the truth. For the essence of the soul, being colourless, formless, and intangible, is visible only to God, its guide." Now the Word issuing forth was the cause of creation; then also he generated himself, "when the Word had become flesh," that He might be seen. The righteous man will seek the discovery that flows from love, to which if he haste he prospers. For it is said, "To him that knocketh, it shall be opened: ask, and it shall be given to you." "For the violent that storm the kingdom " are not so in disputations speeches; but by continuance in a right life and unceasing prayers, are said "to take it by force," wiping away the blots left by their previous sins.

(12) They who know truth in truth, and untruth in untruth, arrive at truth, and follow true desires.

(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."

(7) As, then, the virtues follow one another, why need I say what has been demonstrated already, that faith hopes through repentance, and fear through faith; and patience and practice in these along with learning terminate in love, which is perfected by knowledge? But that is necessarily to be noticed, that the Divine alone is to be regarded as naturally wise. Therefore also wisdom, which has taught the truth, is the power of God; and in it the perfection of knowledge is embraced. The philosopher loves and likes the truth, being now considered as a friend, on account of his love, from his being a true servant. The beginning of knowledge is wondering at objects, as Plato says is in his Theoetetus; and Matthew exhorting in the Traditions, says, "Wonder at what is before you;" laying this down first as the foundation of further knowledge. So also in the Gospel to the Hebrews it is written, "He that wonders shall reign, and he that has reigned shall rest. It is impossible, therefore, for an ignorant man, while he remains ignorant, to philosophize, not having apprehended the idea of wisdom; since philosophy is an effort to grasp that which truly is, and the studies that conduce thereto. And it is not the rendering of one accomplished in good habits of conduct, but the knowing how we are to use and act and labour, according as one is assimilated to God. I mean God the Saviour, by serving the God of the universe through the High Priest, the Word, by whom what is in truth good and right is beheld. Piety is conduct suitable and corresponding to God.
