(1) Chance events for the sake of their originally expected result.
Philosopher Porphyry (c.234 – c.305 AD) indirectly proposes that chance events are for the sake of their originally expected result by suggesting that what the chance events are for the sake of is not what results. There is textual support, at least indirectly, in Phys. II, iv-vi for the interpretation that chance events are for the sake of their originally expected results. In Phys. II, vi, Aristotle says: “chance events do not come to pass for the sake of what actually results.” He then follows up with an example “A is for the sake of B, does not result in B.”
In Aristotle’s limited sense of chance concerning human actions, he has a well-known example of a man going to the market for a purpose other than collecting a debt, but then accidentally recovering the debt from the debtor who is also at the market. In this example, the chance event is the man going to the market, for the sake of a purpose other than collecting the debt. The man’s original intended result is for a purpose other than collecting the debt. What ultimately results is the man collecting the debt. By saying that chance events are for the sake of their originally expected result, it illustrates the man’s reason for being at the market, which is an incidental cause of what he ultimately achieves, i.e. collecting the debt. In fact, what matters in this example is that the man’s ultimate result was unexpected, whether the man’s originally intended result is achieved is not relevant. The man may have finished watching the show he intended to watch or may have successfully completed his business before he runs into his debtor. Along these lines, Lennox
We now apply the interpretation that chance events are for the sake of their originally expected result in Aristotle’s broader sense of chance in the natural realm, i.e. spontaneity in nature or the case of “monsters” where offspring do not resemble their parents De Gen. An. IV, iii-iv (767b 5-6), animal lacking parts (770 b 8-9) or with extra parts or irregular formation (772 b 13-773 a 29). Aristotle has the following definition for spontaneity in Phys. II, vi.
Hence it is clear that events which are among those things which come to be without qualification for the sake of something. When they do not come to be for the sake of the result, and which have an external cause, are due to the spontaneous. (197b14-20)
In addition to suggesting spontaneous events are not for the sake of what results, Aristotle says: “for a stone falls not for the sake of hitting someone, but it falls automatically because it might have been made to fall by someone and for the sake of hitting. (197b30-32)” What would be the originally expected result of a stone falling naturally which ends up hitting someone? Because the ultimate result is that the stone ends up hitting someone, for the ultimate result to be unexpected or accidental, it may be reasonable to say that the originally expected result is for the stone to fall without hitting anyone. However, saying that the stone falls for the sake of not hitting anyone ascribes something to nature that nature does not have, because the stone simply falls without regard as to whether it hits someone or not. Alternatively, if the originally expected result is for the stone to simply fall without regard to whether it hits anyone, it fails to state a purpose. If stone falling were the originally expected result, we would be making the circular statement that stone falls for the sake for stone falling. Therefore, the interpretation that chance events are for the sake of their originally expected results does not work well with Aristotle’s broader sense of chance in the natural realm with external natural causes.
We further examine a case of spontaneity similar to Aristotle’s case of “monsters” where offspring do not resemble their parents. Suppose several seeds are planted according to the conditions needed for the seeds to sprout. While most of the seeds sprout as expected, a couple of seeds fail to sprout for no reason at all. Aristotle attributes the cause of being contrary to nature such as failing to spout as internal in Phys, II, vi:
The difference between spontaneity and what results by chance is greatest in things that come to be by nature; for when anything comes to be contrary to nature, we do not say that it came to be by chance, but by spontaneity. Yet strictly this too is different from the spontaneous proper; for the cause of the latter is external, that of the former internal. (198a33-36)
Here Aristotle suggests that spontaneity in nature with an internal reason is not “chance.” That’s because Aristotle is only talking about chance in the limited sense concerning human actions. Scholars have since characterized spontaneity and monsters as part of Aristotle’s broader sense of chance in the natural realm.
Further, the interpretation that chance events are for the sake of their originally expected result does not seem to express Aristotle’s recognition under his teleology that an event must be recognized as being meaningful for it to be a chance event.
Overall, the interpretation that chance events are for the sake of their originally expected result does not work well. Therefore, I side with Simplicius and Lennox in rejecting this interpretation.
We assume that when we say chance is for the sake of something, chance has a purpose because “for the sake of” implies having a purpose. However, contrary to what he implies in Physics, Aristotle asserts in Posterior Analytics that chance does not occur for a purpose or for the sake of something.
(2) Chance events for the sake of their ultimately achieved result.
Philosopher Simplicius (c.490 – c.560 AD) proposes that chance events are for the sake of their ultimately achieved result. Simplicius suggests that chance events have the appearance of being goal directed because they are, i.e. they are what might have been done for the ultimately achieved result. Lennox adopts this interpretation, following Simplicius’ line of reasoning that the end result is what the chance event would have aimed for if there were foresight. Lennox argues that chance events are for the sake of their ultimately achieved result by accident, without causing the ultimately achieved result.
Thus, the man would have come for the sake of recovering the money when his debtor was collecting contributions, if he had known; in fact, he did not come for the sake of recovering the money, but he happened to come and to do this for the sake of collecting the money (196b34-36).
Perhaps Simplicius and Lennox are correct that chance events in the Aristotelian limited sense of chance in the human realm concerning human actions are for the sake of their ultimately achieved results because the ultimately achieved result is what an agent capable of choices would have wanted, with foresight or retrospective. However, this interpretation can run into practical difficulties in terms of ordinary logical reasoning. With this interpretation, we would say: “the falling apple is for the sake of inspiring the discovery of the laws of gravity upon being observed by Newton.” or “Alexander Fleming’s carelessness in handling the lab sample is for the sake of discovering penicillin.” or “My going about my business as usual with no expectation of running into anyone is for the sake of running into my old friend.” Even if we add “by accident” at the end of each of these sentences as Lennox would have suggested, there is an apparent lack of logic to these statements under our ordinary reasoning.
This interpretation runs into particular difficulty when chance events have chain reactions. The difficulty is illustrated by the well-known story from ancient China.
Near China's northern borders lived a man well versed in the practices of Taoism. His horse, for no reason at all, got into the territory of the northern tribes. Everyone commiserated with him. “Perhaps this will soon turn out to be a blessing,” said the man. After a few months, his animal came back, leading a fine horse from the north. Everyone congratulated him. “Perhaps this will soon turn out to be a cause of misfortune,” said the man. His son became fond of riding the fine horse and eventually broke his thigh bone from falling while riding. Everyone commiserated with him. “Perhaps this will soon turn out to be a blessing,” said the man. One year later, the northern tribes started a big invasion of the border regions. All able-bodied young men took up arms and fought against the invaders, and as a result, around the border nine out of ten young men died. This man's son did not join in the fighting because he was crippled and so the son survived to look after the man in his old age.
The chance event of the man losing his horse belongs to Aristotle’s broader sense of chance in the natural realm with an external cause. Under the current interpretation that chance events are for the sake of their ultimately achieved result, as the above story develops, would we be saying “the man’s loss of his horse is for the sake of bringing back a fine horse,” then “the man’s loss of his horse is for the sake of breaking his son’s thigh bone,” and then “the man’s loss of his horse is for the sake of preserving his son’s life”? The requirement of foresight and retrospective for this interpretation bring about the unwanted burden of having to change the statement as events develop.
Overall, although the interpretation that chance events are for the sake of their ultimately achieved result connects chance events to their ultimately fulfilled result rending chance events meaningful in Aristotle’s teleological framework, it contains a logical defect under ordinary reasoning as something unplanned turns into an aim. It also does not work well for scenarios where there are chain reactions.
(3) Chance events for the sake of what’s meaningful for human happiness.
The interpretation that chance events are for the sake of what’s meaningful for human happiness maintains chance within Aristotle’s teleological context and avoids the logical defect in the preceding interpretation. When interpreting chance events to be for the sake of what’s meaningful for human happiness, we recognize that there are unlimited events that are meaningless and that whenever there is a chance event that is meaningful in terms of man’s aims, i.e. meaningful in terms of human happiness, the chance event is recognized. This interpretation allows chance to fit well in Aristotle’s teleological context because it shows that chance events contribute to the purpose of human happiness. In Aristotelian broader sense of chance in the natural realm, this interpretation distinguishes chance events from other meaningless events by highlighting the fact that chance events have a purpose and are meaningful. In this interpretation, the falling apple that Newton saw, the lab sample that Alexander Fleming carelessly put aside, which would have otherwise be meaningless and would not have been noticed, became meaningful and turned into chance events because of their significance to men’s aims. What is meaningful to human happiness includes both good fortunate and bad fortune.
Applying the interpretation to the case of the man accidentally recovering a debt at the market place, we would be saying that the man goes to the market for the sake of what’s meaningful for his happiness. This is a logical statement as recovering a debt is relevant to the man’s happiness. In the case of the man losing his horse in the story from ancient China, all subsequent events are meaningful for the man’s happiness, from the lost horse bringing back a fine horse, to his son breaking his bone riding the fine horse, to his son’s preservation for not having to join the armed conflict. Therefore, saying that the man’s losing his horse is for the sake of what’s meaningful to his happiness is logical.
It seems that Aristotle makes a broad categorization between what is meaningful and what is not when he says in Phys, II, v: “of things that come to be, some come to be for the sake of something, others not.” Based on that, one may attempt to argue that it is justified to simply categorize chance events as what’s meaningful. However, “for the sake of what’s meaningful for human happiness” may be too general a statement as it makes all chance events indistinguishable. In addition, why would Aristotle use the term something if what he means is the unchangeable what’s meaningful for human happiness? Furthermore, for the sake of something is what he uses for the final cause of physics and the something is meant to be different for different things. Turning something into the constant what’s meaningful for human happiness for chance events would make a glaring exception to how he addresses the final cause of physics.
Therefore, although the interpretation that chance events are for the sake of what’s meaningful for human happiness seems logical and works well in terms of maintaining chance within Aristotle’s teleological framework, it is so general a statement that it make all chance events indistinguishable. It also creates conflict with how Aristotle analyzes the final cause.
(4) Chance events for the sake of what’s meaningful for their ultimately achieved result.
Finally, the interpretation that chance events are for the sake of what’s meaningful for their ultimately achieved results not only puts chance events in Aristotle’s teleological context, it avoids the logical defect of connecting chance events and their ultimately achieved result directly, and it avoids making too general a statement to make all chance events indistinguishable. This interpretation would seem to be our best alternative. Textual support for “chance events are fore the sake of their ultimately achieved result” can support “chance events are fore the sake of what’s meaningful for their ultimately achieved result”, as latter is a refinement of the former. The difference between “ultimately achieved result” and “what’s meaningful for the ultimately achieved result” is the wider array of things that can be relevant to the ultimately achieved result.
Applying the current interpretation to the case of the man accidently collecting his debt at the market, the man’s going to the market is for the sake of what’s meaningful for his recovering his debt. In the case of the man losing his horse in the story from ancient China, the man’s losing his horse is for the sake of what’s meaningful for his lost horse bringing back a fine horse, or for his son’s fond of riding the fine horse, or for his son breaking his bone riding the fine horse, or for his son’s preservation for not having to join the armed conflict. It may seem that this interpretation also requires a shifting description of what the chance event is for the sake of in case of chain events. However, what is underlying the meaningful for all subsequent chain events can be the same. For instance, the man’s lost horse bringing back a fine horse is meaningful for the man’s son becoming fond of riding the fine horse, is meaningful for his son’s breaking a bone, is meaningful for the son’s preservation not having to fight in the armed conflict. In other words, with the current interpretation, what chance events are for the sake of can stay the same while description changes as events develop.
The interpretation that chance events are for the sake of what’s meaningful for their ultimately achieved result is our best alternative and it is a refinement of the view of Simplicius and Lennox.
