41. But, coming to the next point, we are not to reckon among human institutions those things which men have handed down to us, not as arrangements of their own, but as the result of investigation into the occurrences of the past, and into the arrangements of God's providence. And of these, some pertain to the bodily senses, some to the intellect. Those which are reached by the bodily senses we either believe on testimony, or perceive when they are pointed out to us, or infer from experience.
CHAP. 28. — TO WHAT EXTENT HISTORY IS AN AID.
42. Anything, then, that we learn from history about the chronology of past times assists us very much in understanding the Scriptures, even if it be learnt without the pale of the Church as a matter of childish instruction. For we frequently seek information about a variety of matters by use of the Olympiads, and the names of the consuls; and ignorance of the consulship in which our Lord was born, and that in which He suffered, has led some into the error of supposing that He was forty-six years of age when He suffered, that being the number of years He was told by the Jews the temple (which He took as a symbol of His body) was in building.1 Now we know on the authority of the evangelist that He was about thirty years of age when He was baptized;2 but the number of years He lived afterwards, although by putting His actions together we can make it out, yet that no shadow of doubt might arise from another source, can be ascertained more clearly and more certainly from a comparison -of profane history with the gospel. It will still be evident, however, that it was not without a purpose it was said that the temple was forty and six years in building; so that, as this cannot be referred to our Lord's age, it may be referred to the more secret formation of the body which, for our sakes, the onlybegotten Son of God, by whom all things were made, condescended to put on.3 43. As to the utility of history, moreover, passing over the Greeks, what a great question our own Ambrose has set at rest! For, when the readers and admirers of Plato dared calumniously to assert that our Lord Jesus Christ learnt all those sayings of His, which they are compelled to admire and praise, 1 John ii. 19.
3 See above, chap. xvi.
2 Luke iii. 23.
from the books of Plato — because (they urged) it cannot be denied that Plato lived long before the coming of our Lord! — did not the illustrious bishop, when by his investigations into profane history he had discovered that Plato made a journey into Egypt at the time when Jeremiah the prophet was there,4 show that it is much more likely that Plato was through Jeremiah's means initiated into our literature, so as to be able to teach and write those views of his which are so justly praised? For not even Pythagoras himself, from whose successors these men assert Plato learnt theology, lived at a date prior to the books of that Hebrew race, among whom the worship of one God sprang up, and of whom as concerning the flesh our Lord came. And thus, when we reflect upon the dates, it becomes much more probable that those philosophers learnt whatever they said that was good and true from our literature, than that the Lord Jesus Christ learnt from the writings of Plato, — a thing which it is the height of folly to believe.
44. And even when in the course of an historical narrative former institutions of men are described, the history itself is not to be reckoned among human institutions; because things that are past and gone and cannot be undone are to be reckoned as belonging to the course of time, of which God is the author and governor. For it is one thing to tell what has been done, another to show what ought to be done. History narrates what has been done, faithfully and with advantage; but the books of the haruspices, and all writings of the same kind, aim at teaching what ought to be done or observed, using the boldness of an adviser, not the fidelity of a narrator.
CHAP. 29. TO WHAT EXTENT NATURAL SCIENCE IS AN EXEGETICAL AID.
45. There is also a species of narrative resembling description, in which not a past but an existing state of things is made known to those who are ignorant of it. To this species belongs all that has been written about the situation of places, and the nature of animals, trees, herbs, stones, and other bodies. And of this species I have treated above, and have shown that this kind of knowledge is serviceable in solving the difficulties of Scripture, not that these objects are to be used conformably to certain signs as nostrums or the instruments of superstition; for that kind of knowledge I have already set aside as distinct from the lawful and free kind now spoken of. For it is one thing to say: If you bruise down 4 Augustin himself corrected this mistake. Retractations, ii. 4.
55o [Book II.
this herb and drink it, it will remove the pam from your stomach; and another to say: If you hang this herb round your neck, it will remove the pain from your stomach. In the former case the wholesome mixture is approved of, in the latter the superstitious charm is condemned; although indeed, where incantations and invocations and marks are not used, it is frequently doubtful whether the thing that is tied or fixed in any way to the body to cure it, acts by a natural virtue, in which case it may be freely used; or acts by a sort of charm, in which case it becomes the Christian to avoid it the more carefully, the more efficacious it may seem to be. But when the reason why a thing is of virtue does not appear, the intention with which it is used is of great importance, at least in healing or in tempering bodies, whether in medicine or in agriculture.
46. The knowledge of the stars, again, is not a matter of narration, but of description. Very few of these, however, are mentioned in Scripture. And as the course of the moon, which is regularly employed in reference to celebrating the anniversary of our Lord's passion, is known to most people; so the rising and setting and other movements of the rest of the heavenly bodies are thoroughly known to very few. And this knowledge, although in itself it involves no superstition, renders very little, indeed almost no assistance, in the interpretation of Holy Scripture, and by engaging the attention unprofitably is a hindrance rather; and as it is closely related to the very pernicious error of the diviners of the fates, it is more convenient and becoming to neglect it. It involves, moreover, in addition to a description of the present state of things, something like a narrative of the past also; because one may go back from the present position and motion of the stars, and trace by rule their past movements. It involves also regular anticipations of the future, not in the way of forebodings and omens, but by way of sure calculation; not with the design of drawing any information from them as to our own acts and fates, in the absurd fashion of the getiethliaci, but only as to the motions of the heavenly bodies themselves. For, as the man who computes the moon's age can tell, when he has found out her age to-day, what her age was any number of years ago, or what will be her age any number of years hence, in just the same way men who are skilled in such computations are accustomed to answer like questions about every one of the heavenly bodies. And I have stated what my views are about all this knowledge, so far as regards its utility.
CHAP. 30. WHAT THE MECHANICAL ARTS CON- TRIBUTE TO EXEGETICS.
47. Further, as to the remaining arts, whether those by which something is made which, when the effort of the workman is over, remains as a result of his work, as, for example, a house, a bench, a dish, and other things of that kind; or those which, so to speak, assist God in His operations, as medicine, and agriculture, and navigation: or those whose sole result is an action, as dancing, and racing, and wrestling; — in all these arts experience teaches us to infer the future from the past. For no man who is skilled in any of these arts moves his limbs in any operation without connecting the memory of the past with the expectation of the future. Now of these arts a very superficial and cursory knowledge is to be acquired, not with a view to practising them (unless some duty compel us, a matter on which I do not touch at present), but with a view to forming a judgment about them, that we may not be wholly ignorant of what Scripture means to convey when it employs figures of speech derived from these arts.
CHAP. 31. — USE OF DIALECTICS. OF FALLACIES.
48. There remain those branches of knowledge which pertain not to the bodily senses, but to the intellect, among which the science of reasoning and that of number are the chief. The science of reasoning is of very great service in searching into and unravelling all sorts of questions that come up in Scripture, only in the use of it we must guard against the love of wrangling, and the childish vanity of entrapping an adversary. For there are many of what are called sophisms, inferences in reasoning that are false, and yet so close an imitation of the true, as to deceive not only dull people, but clever men too, when they are not on their guard. For example, one man lays before another with whom he is talking, the proposition, "What I am, you are not." The other assents, for the proposition is in part true, the one man being cunning and the other simple. Then the first speaker adds: "lama man; " and when the other has given his assent to this also, the first draws his conclusion: "Then you are not a man." Now of this sort of ensnaring arguments, Scripture, as I judge, expresses detestation in that place where it is said, " There is one that showeth wisdom in words, and is hated;"1 although, indeed, a style of speech which is not intended to entrap, but 1 Qui sophistice loquitur, odibilis est. Ecclus. xx.wii. 20.
Chap. XXXIII.]
55r only aims at verbal ornamentation more than is consistent with seriousness of purpose, is also called sophistical.
49. There are also valid processes of reasoning which lead to false conclusions, by following out to its logical consequences the error of the man with whom one is arguing; and these conclusions are sometimes drawn by a good and learned man, with the object of making the person from whose error these consequences result, feel ashamed of them, and of thus leading him to give up his error, when he finds that if he wishes to retain his old opinion, he must of necessity also hold other opinions which he condemns. For example, the apostle did not draw true conclusions when he said, " Then is Christ not risen," and again, "Then is our preaching vain, and your faith is also vain;"1 and further on drew other inferences which are all utterly false; for Christ has risen, the preaching of those who declared this fact was not in vain, nor was their faith in vain who had believed it. But all these false inferences followed legitimately from the opinion of those who said that there is no resurrection of the dead. These inferences, then, being repudiated as false, it follows that since they would be true if the dead rise not, there will be a resurrection of the dead. As, then, valid conclusions may be drawn not only from true but from false propositions, the laws of valid reasoning may easily be learnt in the schools, outside the pale of the Church. But the truth of propositions must be inquired into in the sacred books of the Church.
CHAP. 32. VALID LOGICAL SEQUENCE IS NOT DEVISED BUT ONLY OBSERVED BY MAN.
50. And yet the validity of logical sequences is not a thing devised by men, but is observed and noted by them that they may be able to learn and teach it; for it exists eternally in the reason of things, and has its origin with God. For as the man who narrates the order of events does not himself create that order; and as he who describes the situations of places, or the natures of animals, or roots, or minerals, does not describe arrangements of man; and as he who points out the stars and their movements does not point out anything that he himself or any other man has ordained; — in the same way, he who says, " When the consequent is false, the antecedent must also be false," says what is most true; but he does not himself make it so, he only points out that it is so. And it is upon this rule that the reasoning I have quoted from the Apostle Paul proceeds. For the antecedent is, "There is no resurrection of the dead," — the position taken up by those whose error the apostle wished to overthrow. Next, from this antecedent, the assertion, viz., that there is no resurrection of the dead, the necessary consequence is, "Then Christ is not risen." But this consequence is false, for Christ has risen; therefore the antecedent is also false. But the antecedent is, that there is no resurrection of the dead. We conclude, therefore, that there is a resurrection of the dead. Now all this is briefly expressed thus: If there is no resurrection of the dead, then is Christ not risen; but Christ is risen, therefore there is a resurrection of the dead. This rule, then, that when the consequent is removed, the antecedent must also be removed, is not made by man, but only pointed out by him. And this rule has reference to the validity of the reasoning, not to the truth of the statements.
CHAP. 33. FALSE INFERENCES MAY BE DRAWN FROM VALID REASONINGS, AND VICE VERSA.
51. In this passage, however, where the argument is about the resurrection, both the law of the inference is valid, and the conclusion arrived at is true. But in the case of false conclusions, too, there is a validity of inference in some such way as the following. Let us suppose some man to have admitted: If a snail is an animal, it has a voice. This being admitted, then, when it has been proved that the snail has no voice, it follows (since when the consequent is proved false, the antecedent is also false) that the snail is not an animal. Now this conclusion is false, but it is a true and valid inference from the false admission. Thus, the truth of a statement stands on its own merits; the validity of an inference depends on the statement or the admission of the man with whom one is arguing. And thus, as I said above, a false inference may be drawn by a valid process of reasoning, in order that he whose error we wish to correct may be sorry that he has admitted the antecedent, when he sees that its logical consequences are utterly untenable. And hence it is easy to understand that as the inferences may be valid where the opinions are false, so the inferences may be unsound where the opinions are true. For example, suppose that a man propounds the statement, "If this man is just, he is good," and we admit its truth. Then he adds, " But he is not just;" and when we admit this too, he draws the conclusion, " Therefore he is not good." Now although every one of these statements may be true, still the principle of the inference is unsound. For it is not true that, as when the consequent is proved false the antecedent is also false, so when the antecedent is proved false the consequent is false. For the statement is true, " If he is an orator, he is a man." But if we add, " He is not an orator," the consequence does not follow, " He is not a man."
CHAP. 34. IT IS ONE THING TO KNOW THE LAWS OF INFERENCE, ANOTHER TO KNOW THE TRUTH OF OPINIONS.
52. Therefore it is one thing to know the *aws of inference, and another to know the truth of opinions. In the former case we learn what is consequent, what is inconsequent, and what is incompatible. An example of a consequent is, " If he is an orator, he is a man; " of an inconsequent, " If he is a man, he is an orator; " of an incompatible, "If he is a man, he is a quadruped." In these instances we judge of the connection. In regard to the truth of opinions, however, we must consider propositions as they stand by themselves, and not in their connection with one another; but when propositions that we are not sure about are joined by a valid inference to propositions that are true and certain, they themselves, too, necessarily become certain. Now some, when they have ascertained the validity of the inference, plume themselves as if this involved also the truth of the propositions. Many, again, who hold the true opinions have an unfounded contempt for themselves, because they are ignorant of the laws of inference; whereas the man who knows that there is a resurrection of the dead is assuredly better than the man who only knows that it follows that if there is no resurrection of the dead, then is Christ not risen.
CHAP. 35. THE SCIENCE OF DEFINITION IS NOT FALSE, THOUGH IT MAY BE APPLIED TO FAL- SITIES.
53. Again, the science of definition, of division, and of partition, although it is frequently applied to falsities, is not itself false, nor framed by man's device, but is evolved from the reason of things. For although poets have applied it to their fictions, and false philosophers, or even heretics — that is, false Christians — to their erroneous doctrines, that is no reason why it should be false, for example, that neither in definition, nor in division, nor in partition, is anything to be included that does not pertain to the matter in hand, nor anything to be omitted that does.
This is true, even though the things to be defined or divided are not true. For even falsehood itself is defined when we say that falsehood is the declaration of a state of things which is not as we declare it to be; and this definition is true, although falsehood itself cannot be true. We can also divide it, saying that there are two kinds of falsehood, one in regard to things that cannot be true at all, the other in regard to things that are not, though it is possible they might be, true. For example, the man who says that seven and three are eleven, says what cannot be true under any circumstances; but he who says that it rained on the kalends of January, although perhaps the fact is not so, says what posssibly might have been. The definition and division, therefore, of what is false maybe perfectly true, although what is false cannot, of course, itself be true.
CHAP. 36. THE RULES OF ELOQUENCE ARE TRUE, THOUGH SOMETIMES USED TO PER- SUADE MEN OF WHAT IS FALSE.
54. There are also certain rules for a more copious kind of argument, which is called eloquence, and these rules are not the less true that they can be used for persuading men of what is false; but as they can be used to enforce the truth as well, it is not the faculty itself that is to be blamed, but the perversity of those who put it to a bad use. Nor is it owing to an arrangement among men that the expression of affection conciliates the hearer, or that a narrative, when it is short and clear, is effective, and that variety arrests men's attention without wearying them. And it is the same with other directions of the same kind, which, whether the cause in which they are used be true or false, are themselves true just in so far as they are effective in producing knowledge or belief, or in moving men's minds to desire and aversion. And men rather found out that these things are so, than arranged that they should be so.
CHAP. 37. USE OF RHETORIC AND DIALECTIC.
55. This art, however, when it is learnt, is not to be used so much for ascertaining the meaning as for setting forth the meaning when it is ascertained. But the art previously spoken of, which deals with inferences, and definitions, and divisions, is of the greatest assistance in the discovery of the meaning, provided only that men do not fall into the error of supposing that when they have learnt these things they have learnt the true secret of a happy life. Still, it sometimes happens that men find less difficulty in attaining the ob- Chap. XXXIX.]
55.
ject for the sake of which these sciences are learnt, than in going through the very intricate and thorny discipline of such rules. It is just as if a man wishing to give rules for walking should warn you not to lift the hinder foot before you set down the front one, and then should describe minutely the way you ought to move the hinges of the joints and knees. For what he says is true, and one cannot walk in any other way; but men find it easier to walk by executing these movements than to attend to them while they are going through them, or to understand when they are told about them. Those, on the other hand, who cannot walk, care still less about such directions, as they cannot prove them by making trial of them. And in the same way a clever man often sees that an inference is unsound more quickly than he apprehends the rules for it. A dull man, on the other hand, does not see the unsoundness, but much less does he grasp the rules. And in regard to all these laws, we derive more pleasure from them as exhibitions of truth, than assistance in arguing or forming opinions, except perhaps that they put the intellect in better training. We must take care, however, that they do not at the same time make it more inclined to mischief or vanity, — that is to say, that they do not give those who have learnt them an inclination to lead people astray by plausible speech and catching questions, or make them think that they have attained some great thing that gives them an advantage over the good and innocent.
CHAP. 38. — THE SCIENCE OF NUMBERS NOT CREATED, BUT ONLY DISCOVERED, BY MAN.
56. Coming now to the science of number, it is clear to the dullest apprehension that this was not created by man, but was discovered by investigation. For, though Virgil could at his own pleasure make the first syllable of Italia long, while the ancients pronounced it short, it is not in any man's power to determine at his pleasure that three times three are not nine, or do not make a square, or are not the triple of three, nor one and a half times the number six, or that it is not true that they are not the double of any number because odd numbers1 have no half. Whether, then, numbers are considered in themselves, or as applied to the laws of figures, or of sounds, or of other motions, they have fixed laws which were not made by man, but which the acuteness of ingenious men brought to light.
57. The man, however, who puts so high a value on these things as to be inclined to boast himself one of the learned, and who does not rather inquire after the source from which those things which he perceives to be true derive their truth, and from which those others which he perceives to be unchangeable also derive their truth and unchangeableness, and who, mounting up from bodily appearances to the mind of man, and finding that it too is changeable (for it is sometimes instructed, at other times uninstructed), although it holds a middle place between the unchangeable truth above it and the changeable things beneath it, does not strive to make all things redound to the praise and love of the one God from whom he knows that all things have their being; — the man, I say, who acts in this way may seem to be learned, but wise he cannot in any sense be deemed.
CHAP. 39. TO WHICH OF THE ABOVE-MEN- TIONED STUDIES ATTENTION SHOULD BE GIVEN, AND IN WHAT SPIRIT.
58. Accordingly, I think that it is well to warn studious and able young men, who fear God and are seeking for happiness of life, not to venture heedlessly upon the pursuit of the branches of learning that are in vogue beyond the pale of the Church of Christ, as if these could secure for them the happiness they seek; but soberly and carefully to discriminate among them. And if they find any of those which have been instituted by men varying by reason of the varying pleasure of their founders, and unknown by reason of erroneous conjectures, especially if they involve entering into fellowship with devils by means of leagues and covenants about signs, let these be utterly rejected and held in detestation.
Let the young men also withdraw their attention from such institutions of men as are unnecessary and luxurious. But for the sake of the necessities of this life we must not neglect the arrangements of men that enable us to carry on intercourse with those around us. I think, however, there is nothing useful in the other branches of learning that are found among the heathen, except information about objects, either past or present, that relate to the bodily senses, in which are included also the experiments and conclusions of the useful mechanical arts, except also the sciences of reasoning and of number. And in regard to all these we must hold by the maxim, " Not too much of anything; " especially in the case of those which, pertaining as they do to the senses, are subject to the relations of space and time.2 2 Ne quid nitm's. — Terence, A tidria, act i. scene 1.
[Book II- 59. What, then, some men have done in regard to all words and names found in Scripture, in the Hebrew, and Syriac, and Egyptian, and other tongues, taking up and interpreting separately such as were left in Scripture without interpretation; and what Eusebius has done in regard to the history of the past with a view to the questions arising in Scripture that require a knowledge of history for their solution; — what, I say, these men have done in regard to matters of this kind, making it unnecessary for the Christian to spend his strength on many subjects for the sake of a few items of knowledge, the same, I think, might be done in regard to other matters, if any competent man were willing in a spirit of benevolence to undertake the labor for the advantage of his brethren. In this way he might arrange in their several classes, and give an account of the unknown places, and animals, and plants, and trees, and stones, and metals, and other species of things that are mentioned in Scripture, taking up these only, and committing his account to writing. This might also be done in relation to numbers, so that the theory of those numbers, and those only, which are mentioned in Holy Scripture, might be explained and written down. And it may happen that some or all of these things have been done already (as I have found that many things I had no notion of have been worked out and committed to writing by good and learned Christians), but are either lost amid the crowds of the careless, or are kept out of sight by the envious. And I am not sure whether the same thing can be done in regard to the theory of reasoning; but it seems to me it cannot, because this runs like a system of nerves through the whole structure of Scripture, and on that account is of more service to the reader in disentangling and explaining ambiguous passages, of which I shall speak hereafter, than in ascertaining the meaning of unknown signs, the topic I am now discussing.
CHAP. 40. WHATEVER HAS BEEN RIGHTLY SAID BY THE HEATHEN, WE MUST APPROPRIATE TO OUR USES.
60. Moreover, if those who are called philosophers, and especially the Platonists, have said aught that is true and in harmony with our faith, we are not only not to shrink from it, but to claim it for our own use from those who have unlawful possession of it. For, as the Egyptians had not only the idols and heavy burdens which the people of Israel hated and fled from, but also vessels and ornaments of gold and silver, and garments, which the
