On the Trinity

25. Wherefore it now remains to consider, in what manner we ought not to follow these, who profess that they will lead by reason. For how we may without fault follow those who bid us to believe, hath been already said: but unto these who make promises of reason certain think that they come, not only without blame, but also with some praise: but it is not so. For there are two (classes of) persons, praiseworthy in religion; one of those who have already found, whom also we must needs judge most blessed; another of those who are seeking with all earnestness and in the right way. The first, therefore, are already in very possession, the other on the way, yet on that way whereby they are most sure to arrive. There are three other kinds of men altogether to be disapproved of and detested. One is of those who hold an opinion, that is, of those who think that they know what they know not. Another is of those who are indeed aware that they know not, but do not so seek as to be able to find. A third is of those who neither think that they know, nor wish to seek. There are also three things, as it were bordering upon one another, in the minds of men well worth distinguishing; understanding, belief, opinion. And, if these be considered by themselves, the first is always without fault, the second sometimes with fault, the third never without fault. For the understanding of matters great, and honorable, and even divine, is most blessed. But the understanding of things unnecessary is no injury; but perhaps the learning was an injury, in that it took up the time of necessary matters. But on the matters themselves that are injurious, it is not the understanding, but the doing or suffering them, that is wretched. For not, in case any understand how an enemy may be slain without danger to himself, is he guilty from the mere understanding, not the wish; and, if the wish be absent, what can be called more innocent? But belief is then worthy of blame, when either any thing is believed of God which is unworthy of Him, or any thing is over easily believed of man. But in all other matters if any believe aught, provided he understand that he knows it not, there is no fault. For I believe that very wicked conspirators were formerly put to death by the virtue of Cicero; but this I not only know not, but also I know for certain that I can by no means know. But opinion is on two accounts very base; in that both he who hath persuaded himself that he already knows, cannot learn; provided only it may be learnt; and in itself rashness is a sign of a mind not well disposed. For even if any suppose that he know what I said of Cicero, (although it be no hindrance to him from learning, in that the matter itself is incapable of being grasped by any knowledge;) yet, (in that he understands not that there is a great difference, whether any thing be grasped by sure reason of mind, which we call understanding, or whether for practical purposes it be entrusted to common fame or writing, for posterity to believe it,) he assuredly errs, and no error is without what is base. What then we understand, we owe to reason; what we believe, to authority; what we have an opinion on, to error. But every one who understands also believes, and also every one who has an opinion believes; not every one who believes understands, no one who has an opinion understands. Therefore if these three things be referred unto the five kinds of men, which we mentioned a little above; that is, two kinds to be approved, which we set first, and three that remain faulty; we find that the first kind, that of the blessed, believe the truth itself; but the second kind, that of such as are earnest after, and lovers of, the truth, believe authority. In which kinds, of the two, the act of belief is praiseworthy. But in the first of the faulty kinds, that is, of those who have an opinion that they know what they know not, there is an altogether faulty credulity. The other two kinds that are to be disapproved believe nothing, both they who seek the truth despairing of finding it, and they who seek it not at all. And this only in matters which pertain unto any system of teaching. For in the other business of life, I am utterly ignorant by what means a man can believe nothing. Although in the case of those also they who say that in practical matters they follow probabilities, would seem rather to be unable to know than unable to believe. For who believes not what he approves? or how is what they follow probable, if it be not approved? Wherefore there may be two kinds of such as oppose the truth: one of those who assail knowledge alone, not faith; the other of those who condemn both: and yet again, I am ignorant whether these can be found in matters of human life. These things have been said, in order that we might understand, that, in retaining faith, even of those things which as yet we comprehend not, we are set free from the rashness of such as have an opinion. For they, who say that we are to believe nothing but what we know, are on their guard against that one name “opining,” which must be confessed to be base and very wretched, but, if they consider carefully that there is a very great difference, whether one think that he knows, or moved by some authority believe that which he understands that he knows not, surely he will escape the charge of error, and inhumanity, and pride.
