Buridan’s ass: Another dilemma?


When I was writing about dilemmas, I had to think of Buridan’s ass. Maybe you remember that I wrote about this animal before. If not, you can find it here, but for your convenience I’ll repeat the essence of the case: A rational hungry donkey is placed between two equidistant and identical haystacks. The surrounding environments on both sides are also identical. The donkey cannot choose between the two haystacks and so dies of hunger, which is simply irrational.
The case is usually referred to as Buridan’s ass, after the French philosopher Jean Buridan (1295-1363), but actually, it’s not correct, for philosophers before him – including Aristotle – had already examined it, although often in another version. Also after Buridan, the case has been discussed again and again, for instance by Leibniz. Usually, it is seen as a paradox, which it is, but is it also a dilemma?
Let’s see when we call a case a dilemma (cf. my blog last week). In the first place the agent must face a situation in which he or she has to choose and, indeed, Buridan’s ass (donkey) must choose between two possible actions: eating the left haystack or eating the right haystack. However, the need to make a choice doesn’t as such place the agent in a dilemma. A choice is only a dilemma, if by making a choice you break a moral rule, say rule MR1. It is possible to avoid breaking MR1 by making another choice, but only by breaking another moral rule MR2. In other words, any choice leads to breaking a moral rule, so that, whatever you do, you’ll do something wrong. However, for Buridan’s ass, any choice is good, unless, for instance, by eating from these haystacks, the animal steals hay from the owner of the stacks. In that case, the ass is in the dilemma to steal or to eat. (When by eating only from one haystack, the ass steals hay, which one to eat is obvious, of course)
This brings me to Montaigne. In his very short essay “How our mind hinders ourself” (Essays, Book II-14), Montaigne tells us:
“’T is a pleasant imagination to fancy a mind exactly balanced betwixt two equal desires: for, doubtless, it can never pitch upon either, forasmuch as the choice and application would manifest an inequality of esteem; and were we set betwixt the bottle and the ham, with an equal appetite to drink and eat, there would doubtless be no remedy but we must die of thirst and hunger.” This is the situation Buridan’s ass faces: The ass cannot choose, since the animal has no criterion to choose and so the ass will die. However, according to Montaigne, such a situation is unreal and it cannot happen: “Nothing presents itself to us wherein there is not some difference, how little soever; and that, either by the sight or touch, there is always some choice that, though it be imperceptibly, tempts and attracts us.” Applied to the case of Buridan’s ass: How equal the two haystacks may seem to be, they always are a little bit different, which makes that the ass prefers either the left one or the right one.
What must the ass do in case the animal would steal when eating from the haystacks? Also then the solution of the problem is easy, I think: It's better to steal than to die.
According to Markus Gabriel, there are no dilemmas: When one must choose, there is always a better choice and a less good choice. If not, then we are in a tragedy, he says. However, as I showed last week, even in a tragedy we can face a dilemma. It’s not Gabriel but Montaigne who has explained why, actually, there are no dilemmas: In a dilemma there is always one lemma that is to be preferred. The problem then is to determine which one it is. If Montaigne is right, there may not be dilemmas, but there still are difficult choices.

The ass, according to this old dilemma, has no free will---no ability to choose between two clear and present options. This is presented as fact(?) in the story. I wonder, though. Suppose one were to do an empirical experiment with, say, a dozen hungry donkeys, offering each the same choice as in the original experiment? How would we view the outcome if half of the animals chose a haystack, rather than starving? Donkeys ARE obstinate. But, they are not dumb. If there are no dilemmas, then it seems to follow there are no paradoxes either. Except maybe in quantum mechanics. Free will is another old argument. It is reasonably certain, other things being equal, that a hungry human, offered two meals under similar experimental conditions, will choose one plate or the other. And then eat both, if she is hungry enough. That looks like free will to me. No lemmas at all. Or paradoxes. This is or is not a thought experiment.

The ass has free will, to my mind, but it is so rational that it cannot choose. And that’s just the paradox. But real asses have also emotions and that’s why real asses will simply eat from one of the haystacks, or from both. As so often in thought experiments, the result is dependent on its suppositions. However, I wanted to investigate whether the paradox is also a dilemma, and following Montaigne, I concluded that it is not. But following Montaigne, also a completely rational ass will start to eat from one of the haystacks, for according Montaigne it cannot be that the haystacks are completely the same. Also the circumstances cannot make that there is not even a little preference for one haystack. So, rational or not, an ass will always start to eat. And so do humans when they are hungry and thirsty will do, so Montaigne. And I fully agree with him. So, the paradox doesn’t work (unless you start from irreal suppositions) and it’s not a dilemma.
