Disclosure of the Monstrous Tenets of the Manichæans
43 What then remains, but that you should cease saying that you have in your eyes, nose, and palate sufficient means of testing the presence of the divine part in material objects? And, without these means, how can you tell not only that there is a greater part of God in plants than in flesh, but that there is any part in plants at all? Are you led to think this by their beauty— not the beauty of agreeable color, but that of agreement of parts? An excellent reason, in my opinion. For you will never be so bold as to compare twisted pieces of wood with the bodies of animals, which are formed of members answering to one another. But if you choose the testimony of the senses, as those must do who cannot see with their mind the full force of existence, how do you prove that the substance of good escapes from bodies in course of time, and by some kind of attrition, but because God has gone out of it, according to your view, and has left one place for another? The whole is absurd. But, as far as I can judge, there are no marks or appearances to give rise to this opinion. For many things plucked from trees, or pulled out of the ground, are the better of some interval of time before we use them for food, as leeks and endive, lettuce, grapes, apples, figs, and some pears; and there are many other things which get a better color when they are not used immediately after being plucked, besides being more wholesome for the body, and having a finer flavor to the palate. But these things should not possess all these excellent and agreeable qualities, if, as you say, they become more destitute of good the longer they are kept after separation from their mother earth. Animal food itself is better and more fit for use the day after the animal is killed; but this should not be, if, as you hold, it possessed more good immediately after the slaughter than next day, when more of the divine substance had escaped.
44. Who does not know that wine becomes purer and better by age? Nor is it, as you think, more tempting to the destruction of the senses, but more useful for invigorating the body—only let there be moderation, which ought to control everything. The senses are sooner destroyed by new wine. When the must has been only a short time in the vat, and has begun to ferment, it makes those who look down into it fall headlong, affecting their brain, so that without assistance they would perish. And as regards health, every one knows that bodies are swollen up and injuriously distended by new wine? Has it these bad properties because there is more good in it? Are they not found in wine when old because a good deal of the divine substance has gone? An absurd thing to say, especially for you, who prove the divine presence by the pleasing effect produced on your eyes, nose, and palate! And what a contradiction it is to make wine the poison of the princes of darkness, and yet to eat grapes! Has it more of the poison when in the cup than when in the cluster? Or if the evil remains unmixed after the good is gone, and that by the process of time, how is it that the same grapes, when hung up for awhile, become milder, sweeter, and more wholesome? Or how does the wine itself, as already mentioned, become purer and brighter when the light has gone, and more wholesome by the loss of the beneficial substance?
45. What are we to say of wood and leaves, which in course of time become dry, but cannot be the worse on that account in your estimation? For while they lose that which produces smoke, they retain that from which a bright flame arises; and, to judge by the clearness, which you think so much of, there is more good in the dry than in the green. Hence you must either deny that there is more of God in the pure light than in the smoky one, which will upset all your evidences; or you must allow it to be possible that, when plants are plucked up, or branches plucked off, and kept for a time, more of the nature of evil may escape from them than of the nature of good. And, on the strength of this, we shall hold that more evil may go off from plucked fruits; and so more good may remain in animal food. So much on the subject of time.
46. As for motion, and tossing, and rubbing, if these give the divine nature the opportunity of escaping from these substances, many things of the same kind are against you, which are improved by motion. In some grains the juice resembles wine, and is excellent when moved about. Indeed, as must not be overlooked, this kind of drink produces intoxication rapidly; and yet you never called the juice of grain the poison of the princes of darkness. There is a preparation of water, thickened with a little meal, which is the better of being shaken, and, strange to say, is lighter in color when the light is gone. The pastry cook stirs honey for a long time to give it this light color, and to make its sweetness milder and less unwholesome: you must explain how this can come from the loss of good. Again, if you prefer to test the presence of God by the agreeable effects on the hearing, and not sight, or smell, or taste, harps get their strings and pipes their bones from animals; and these become musical by being dried, and rubbed, and twisted. So the pleasures of music, which you hold to have come from the divine kingdom, are obtained from the refuse of dead animals, and that, too, when they are dried by time, and lessened by rubbing, and stretched by twisting. Such rough treatment, according to you, drives the divine substance from living objects; even cooking them, you say, does this. Why then are boiled thistles not unwholesome? Is it because God, or part of God, leaves them when they are cooked?
47. Why mention all the particulars, when it is difficult to enumerate them? Nor is it necessary; for every one knows how many things are sweeter and more wholesome when cooked. This ought not to be, if, as you suppose, things lose the good by being thus moved about. I do not suppose that you will find any proof from your bodily senses that flesh is unclean, and defiles the souls of those who eat it, because fruits, when plucked and shaken about in various ways, become flesh; especially as you hold that vinegar, in its age and fermentation, is cleaner than wine, and the mead you drink is nothing else than cooked wine, which ought to be more impure than wine, if material things lose the divine members by being moved about and cooked. But if not, you have no reason to think that fruits, when plucked, kept, handled, cooked, and digested, are forsaken by the good, and therefore supply most unclean matter for the formation of bodies.
48. But if it is not from their color and appearance, and smell and taste, that you think the good to be in these things, what else can you bring forward? Do you prove it from the strength and vigor which those things seem to lose when they are separated from the earth and put to use? If this is your reason (though its erroneousness is seen at once, from the fact that the strength of some things is increased after their separation from the earth, as in the case already mentioned of wine, which becomes stronger from age)—if the strength, then, is your reason, it would follow that the part of God is to be found in no food more abundantly than in flesh. For athletes, who especially require vigor and energy, are not in the habit of feeding on cabbage and fruit without animal food.
