The Being Which This Science Investigates

  Chapter 2: 1026a 33-1027a 28

             543. Being in an unqualified sense has various meanings, of which one is the accidental, and another the true (and non-being may signify the false); and besides these there are the categorical figures, for example, the what, of what sort, how much, where, when, and anything else which signifies in this way; and besides all of these there is the potential and the actual.

             544. Since being is used in many senses, then, we must speak first of the accidental, because there is no speculation about it. And this is indicated by the fact that there is no science, either practical or speculative, that investigates it. For one who builds a house does not simultaneously cause all traits that are accidental to the completed house, since these are infinite in number. For nothing prevents the completed house from being pleasant to some, harmful to others, useful to others, and different, as I may say, from all other things, none of which the art of building produces. And similarly neither does the geometrician speculate about things which are accidents of figures in this way, nor whether a triangle differs from a triangle having two right angles.

             545. And this is understandable, because the accidental is in a sense being only in name.

             546. Hence in a way Plato was not wrong when he said that sophistry deals with non-being. For the arguments of the sophists, as I may say, are concerned chiefly with the accidental; [for example, they ask] whether the musical and the grammatical are the same or different; and whether musical Coriscus and Coriscus are the same; and whether everything which is but has not always been has come to be, so that if one who is musical has become grammatical, then one who is grammatical has become musical; and all other such arguments. For the accidental seems to be close to non-being.

             547. Now this is also clear from these arguments: there is generation and corruption of those things which are in another way, but not of those things which are by accident.

             548. Yet concerning the accidental it is necessary to state further, so far as it is possible, what its nature is and by what cause it exists; and perhaps at the same time it will also become evident why there is no science of it.

             549. Therefore, since there are some beings which always are in the same way and of necessity (not necessity in the sense of compulsion, but in the sense of that which cannot be otherwise), and others which are neither of necessity nor always, but for the most part, this is the principle and this the cause of the accidental.

             550. For that which is neither always nor for the most part, we call the accidental. For example, if there should be cold and wintry weather during the dog days, we say that this is accidental; but not if the weather is sultry and hot, because the latter occurs either always or for the most part, whereas the former does not. And it is accidental for a man to be white, for this is so neither always nor for the most part; but it is not accidental for him to be an animal. And it is accidental if a builder produces health, because it is not a builder but a physician who is naturally fitted to do this; but it is accidental for a builder to be a physician. Again, a confectioner, aiming to prepare something palatable, may produce something health-giving; but not according to the confectioner's art. Hence we say that it was accidental. And while there is a sense in which he produces it, he does not produce it in a primary and proper sense. For there are other powers which sometimes are productive of other things, but there is no art or determinate power which is productive of the accidental; for the cause of things which are or come to be by accident is also accidental.

             551. Hence, since not all things are or come to be of necessity and always, but most things occur for the most part, the accidental must exist; for example, a white man is neither always nor for the most part musical. But since this occurs only occasionally, it must be accidental; otherwise everything would be of necessity. Hence matter is the contingent cause of the accidental, which happens otherwise than usually occurs. And we must take as our starting point this question: Is there nothing that is neither always nor for the most part, or is this impossible? There is, then, besides these something which is contingent and accidental. But then there is the question: Does that which occurs for the most part and that which occurs always, have no existence, or are there some beings which are eternal? These questions must be investigated later (1055).

             552. However, it is evident that there is no science of the accidental, for all scientific knowledge is of that which is always or for the most part; otherwise how could one be taught or teach anyone else? For a thing must be defined either as being so always or for the most part; for example, honey-water is beneficial in most cases to those with a fever. But with regard to what happens in the other cases, it will be impossible to state when they occur, for example, at the new moon; for whatever happens at the new moon also happens either always or for the most part; but the accidental is contrary to this. We have explained, then, what the accidental is, and by what cause it exists, and that there is no science of it.

COMMENTARY

             1171. Here Aristotle indicates with what beings this science chiefly intends to deal; and in regard to this he does three things. First (543:C 1171), he recalls the ways in which things are said to be; second (544:C 1172), he establishes the nature of the two kinds of being with which he is not chiefly concerned ("Since being"); and third (559:C 1241), he shows that it is not his chief aim to consider these two kinds of being ("But since combination").

             Accordingly he says, first (543), that being in an unqualified sense, i.e., in a universal sense, is predicated of many things, as has been stated in Book V (435:C 885). In one sense being means what is accidental; and in another sense it means the same thing as the truth of a proposition (and non-being the same as the falseness of a proposition); and in a third sense being is predicated of the things contained under the categorical figures; for example, the what, of what sort, how much, and so on; and in a fourth sense, in addition to all of the above, being applies to what is divided by potentiality and actuality.

             1172. Since being (544).

             Here he deals with the senses of being which he intends to exclude from this science. First (544:C 1172), he deals with accidental being; and second (556:C 1223), with being which is identical with the true ("Again, being in the sense of the true").

             In regard to the first he does two things. First, he shows that there can be no science of the accidental. Second (548:C 1180), he establishes the things that must be considered about accidental being ("Yet concerning the accidental").

             He says, first (544), that since being is used in many senses, as has been stated (543:C 1171), it is necessary first of all to speak of accidental being, so that anything which has the character of being in a lesser degree may first be excluded from the study of this science. And with regard to this kind of being it must be said that no speculation of any science can be concerned with it; and he proves this in two ways.

             1173. He does this first by giving a concrete indication. He says that the impossibility of there being any speculation about accidental being is indicated by the fact that no science, howsoever "investigative" it may be, or "thoughtful" as another translation says, i.e., no matter how carefully it investigates the objects which come within its scope, is found to deal with accidental being. No practical science (and this is divided into the science of action and productive science, as was said above [534:C 1152]) is concerned with it, nor even any speculative science.

             1174. He makes this evident, first, in the case of the practical sciences; for one who builds a house, granted that he builds it, is only an accidental cause of those things which are accidental to the completed house, since these are infinite in number and thus cannot come within the scope of art. For nothing prevents the completed house from being "pleasant," or delightful, to those who dwell there happily; "harmful" to those who suffer some misfortune occasioned by it; "useful" to those who acquire some profit from it; and also "different" from and unlike all other things. But the art of building does not produce any of the things which are accidental to a house, but only produces a house and the things which are essential to it.

             1175. Then he shows that the same thing is true in the case of the speculative sciences, because similarly neither does geometry speculate about those things which are accidents "of figures in this way," i.e., accidentally, but only about those attributes which belong essentially to figures. For it speculates about a triangle being a figure having "two right angles," i.e., having its three angles equal to two right angles; but it does not speculate whether a triangle is anything else, such as wood or something of the sort, because these things pertain to a triangle accidentally.

             1176. And this is understandable (545).

             Second, he proves the same thing by means of an argument. He says it is reasonable that no science should speculate about accidental being, because a science studies those things which are beings in a real sense, but accidental being is in a sense being only in name, inasmuch as one thing is predicated of another. For each thing is a being insofar as it is one. But from any two things which are accidentally related to each other there comes to be something that is one only in name, i.e., inasmuch as one is predicated of the other, for example, when the musical is said to be white, or the converse. But this does not happen in such a way that some one thing is constituted from whiteness and the musical.

             1177. Hence in a way (546).

             He proves in two ways that accidental being is in a sense being only in name. He does this, first, on the authority of Plato; and second (547:C 1179), by an argument ("Now this is").

             He says that since accidental being is in a sense being only in name, Plato in a way was not wrong when, in allotting different sciences to different kinds of substance, he assigned sophistical science to the realm of non-being. For the arguments of the sophists are concerned chiefly with the accidental, since hidden paralogisms have the fallacy of accident as their principal basis.

             1178. Therefore in the first book of the Sophistical Refutations it is said that in arguing against wise men the sophists construct syllogisms that are based on the accidental. This is evident, for example, in these paralogisms in which the question is raised whether the musical and the grammatical are the same or different. Let us construct such a paralogism. The musical differs from the grammatical; but the musical is the grammatical; hence the musical differs from itself. For the musical differs from the grammatical essentially speaking, but the musical is the grammatical by accident. Little wonder then that an absurd conclusion follows, for what is accidental is not distinguished from what is essential. And it would be similar if we were to speak thus: Coriscus differs from musical Coriscus; but Coriscus is musical Coriscus; therefore Coriscus differs from himself. Here too no distinction is drawn between what is accidental and what is essential. And it would be the same if we were to say: everything which is and has not always been, has come to be; but the musical is grammatical and has not always been so; therefore it follows that the musical has become grammatical and that the grammatical has become musical. But this is false, because no process of generation terminates in the grammatical being musical, but one process of generation terminates in a man being grammatical and another in a man being musical. It is also evident that in this argument the first statement is true of something that has being essentially, whereas in the second something is assumed that has being only by accident. And it is similar in all such argument based on the fallacy of accident. For accidental being seems to be close to non-being; and therefore sophistics, which is concerned with the apparent and nonexistent, deals chiefly with the accidental.

             1179. Now this is also clear (547).

             Second, he proves the same thing by an argument. He says that it is also evident, from these arguments which the sophists use, that the accidental is close to non-being; for there is generation and corruption of those things which are beings in a different way than the accidental is, but there is neither generation nor corruption of the accidental. For the musical comes to be by one process of generation and the grammatical by another, but there is not one process of generation of the grammatical musical as there is of two-footed animal or of risible man. Hence it is evident that accidental being is not called being in any true sense.

             1180. Yet concerning the accidental (548).

             He now establishes the truth about accidental being insofar as it is possible to do so. For even though those things which are properly accidental do not come within the scope of any science, still the nature of the accidental can be considered by some science. This is also what happens in the case of the infinite; for even though the infinite as infinite remains unknown, still some science treats of the infinite as infinite.

             In regard to this he does two things. First (548), he settles the issue regarding those points which should be investigated about accidental being. Second (553:C 1191), he rejects an opinion that would abolish accidental being ("Now it is evident").

             1181. In regard to the first he does two things. First (548), he says that there are three points which must be discussed about accidental being, insofar as it is possible to treat of it, namely, what its nature is, and what causes it; and from this the third will become evident, why there can be no science of it.

             1182. Therefore, since there are (549).

             He discusses these three points. First, he shows what the cause of the accidental is. He says that there are some beings which always are in the same way and of necessity (not in the sense in which necessity is taken to mean compulsion, but in the sense of that which cannot be otherwise than it is, as "Man is an animal"); and there are other beings which are neither always nor of necessity, but for the most part, i.e., in the majority of cases, and "this," i.e., what occurs in the majority of cases, is the principle and the cause of the accidental. For in the case of those things which always are there can be nothing accidental, because only that which exists of itself can be necessary and eternal, as is also stated in Book V (422:C 839). Hence it followsthat accidental being can be found only in the realm of contingent things.

             1183. But that which is contingent, or open to opposites, cannot as such be the cause of anything. For insofar as it is open to opposites it has the character of matter, which is in potency to two opposites; for nothing acts insofar as it is in potency. Hence a cause which is open to opposites in the way that the will is, in order that it may act, must be inclined more to one side than to the other by being moved by the appetible object, and thus be a cause in the majority of cases. But that which takes place in only a few instances is the accidental, and it is this whose cause we seek. Hence it follows that the cause of the accidental is what occurs in the majority of cases, because this fails to occur in only a few instances. And this is what is accidental.

             1184. For that which (550).

             Second, he exposes the nature of accidental being; and he speaks thus: that which exists for the most part is the cause of the accidental, because we call that accidental which is neither always nor for the most part. And this is the absence of what occurs for the most part; so that "if there should be wintry weather," i.e., a period of rain and cold, "during the dog days," i.e., in the days of the dog star, we say that this is accidental. But we do not say this "if the weather is sultry" during that time, i.e., if there is a period of drought and heat; for the latter occurs always or almost always, but the former does not. Similarly we say that it is accidental for a man to be white, because this is so neither always nor for the most part. But we say that man is an animal essentially, not accidentally, because this is so always. And similarly a builder causes health accidentally, because a builder inasmuch as he is a builder is not naturally fitted to cause health, but only a physician can do this. However, a builder may cause health inasmuch as he happens to be a physician. Similarly a confectioner, or cook, "aiming," i.e., intending, to prepare "something palatable," or delightful in the line of food, may make something health-giving when he prepares a tasty dish. For food which is good and delightful sometimes promotes health. But it is not according to the "confectioner's art," i.e., the culinary art, that he produces something health-giving, but something delightful. And for this reason we say that this is accidental.

             1185. And it should be noted that in the first example the accidental came about insofar as two things happen to occur at the same time; in the second, insofar as two things happen to be present in the same subject, as white and man; in the third, insofar as the same efficient cause happens to be a twofold agent, as a builder and a physician; and in the fourth, insofar as the effect happens to be twofold, as health and pleasure in the case of food; for while a cook prepares a pleasing dish, nevertheless this happens to be health-giving by accident. In fact a cook prepares something health-giving only in a secondary sense but not in a primary and proper sense, because an art operates through knowledge. Hence whatever lies outside the knowledge of an art is not produced primarily and properly by that art. Therefore the accidental, which lies outside the knowledge of an art, is not produced by art. For there are certain determinate powers which sometimes are productive of other beings which have being in the proper sense of the term, but there is no art or determinate power which is productive of beings in an accidental sense. Now the cause of those things which are or come to be by accident must be an accidental cause and not a proper cause. For effect and cause are proportionate to each other; and therefore whatever is an accidental effect has only an accidental cause, just as an effect in the proper sense has a cause in the proper sense.

             1186. And since he had said above (549:C 1182) that the cause of the accidental is what occurs for the most part, therefore when he says "Hence, since not all (551)," he shows how the accidental exists as a result of what occurs for the most part. He says that, since not all things are or come to be always and of necessity, "but most things happen for the most part," i.e., in the majority of cases, therefore the accidental must exist; and this is what does not occur always or for the most part, as when I say "The white man is musical." Yet because this sometimes happens, although not always or in the majority of cases, it follows that this comes about by accident. For if that which occurs only occasionally were never to occur, then that which occurs in the majority of cases would never fail to occur but would be always and of necessity. Thus all things would be eternal and necessary. But this is false. And since that which occurs in the majority of cases fails to occur because of matter (which is not completely subject to the active power of the agent, as happens in the majority of cases), then matter is the cause of that which happens to be otherwise "than usually occurs," i.e., of what happens only occasionally. This cause, I say, is not a necessary cause but a contingent one.

             1187. Granted that not all things are necessary but that there is something which is neither always nor for the most part, then we must take as our starting-point the question whether there is nothing that is neither always nor for the most part. But obviously this is impossible; for since that which occurs for the most part is the cause of the accidental, then both that which always is and that which is for the most part must exist. Hence anything besides the things just mentioned is an accidental being.

             1188. However, the question whether that which occurs for the most part is found in some being, and whether that which occurs always is not found in any being, or whether there are some things which are eternal, must be dealt with later in Book XII (1055:C 2488), where he will show that there are some substances which are eternal. Hence in the first question he asks whether all things are accidental; and in the second, whether all things are contingent and nothing is eternal.

             1189. However, it is evident (552).

             Here he establishes the third point, namely, that there is no science of the accidental. He says that this is evident from the fact that every science is concerned with what is either always or for the most part. Therefore, since the accidental occurs neither always nor for the most part, there will be no science of it. He proves the first thus: one cannot be taught by another or teach another about something which does not occur either always or for the most part; for anything that may be taught must be defined on the grounds that it is so either always or for the most part; for example, that "honey-water" (a mixture of honey and water) is beneficial to those with a fever, is defined as something that occurs for the most part.

             1190. But with regard to "what happens in the other cases (552)," i.e., in the case of things which are neither always nor for the most part, it cannot be said when they will occur, for example, at the time of the new moon; for whatever is destined to happen at that time also happens either always or for the most part. Or his statement about the new moon can be another example of something that is defined as occurring always; and he adds the phrase "or for the most part" because of the way in which the accidental differs, because it does not occur in either of these ways. Hence he adds that "the accidental is contrary to this," i.e., contrary to what occurs always or for the most part. And this is the minor premise of the principal argument used above. In bringing his discussion to a close he mentions the points which have been explained, namely, what the accidental is, and what its cause is, and that there can be no science of it.
