Buridan's internet

Buridan’s ass would doubtless have hated the internet. The same old blues, he’d think, multiplied infinitely. Or perhaps, and this is the bet every Internet marketer and Google stockholder makes, he would have loved it, as craving becomes an addiction to choice. We begin by looking for the cheapest price, and we end by spending hours looking at Airbnb pictures and commenting on how they could possibly thought that photographing a corner of the bathroom was of any interest to the curious renter.

This is, at least, my experience. I become more asslike as I realize that possible worlds are unfolding before me in cosmic vistas, that one of my childhood dreams – invisibly entering a house – is being realized on a frightening scale, and I have merely to put the cursor on another link to send another shot to whatever part of my brain that is dedicated to invidious comparisons. However, there’s a point, a sad point, in which the whole expedition upon which I have embarked – to find, say, a cheap Airbnb in X – begins to lose its purpose, in which the best price, or the best looking rental, or the best location, or the best references, loses its practical side, because nothing, it turns out, is exactly, every jot and tittle, what I want, even if, before I began the expedition, my desires were of a vagueness… It becomes, instead, an indicator of more – of the “there must be more” that so often besets the poor commoditized consumer, in fatal foreplay with his own want-y self.

John Buridan, like any medieval worth his tomes, left behind a considerable amount of text. However, there is no textual anchor in that corpus for the ass story, although there are plenty other paradoxes. The story goes like this: an ass is driven to stand between two exactly similar bales of hay. If we suppose that the ass simply acts on a calculation that serves to maximize his desire, he would find no reason to prefer one to the other. Thus, he would continually stand there, calculating, until he starved to death.

Buridan apparently used this parable orally, when teaching his students, and it was passed down after he died so that it was known to Spinoza, who is one of the first to mention the story.

Crucially, the ass is between two parity products. Two bales of hay that are composed of just the kind of saliva inducing stuff that donkey’s crave. The donkey has found a strange spot in the human universe, an equilibrium spot, where there is no more reason to chose bale “a” then to chose “b”. Being a mule calculator, an asinus economicus, the mule has obviously read up on ranked preferences and is way ahead of Kenneth Arrow on the impossibility of the three candidate rank ordering, at least if we are to satisfy certain classical criteria, such as Pareto optimality.

Buridan’s ass has spawned, as such things do, a whole subliterature in philosophy. Many return to Spinoza’s analysis in Ethics II, 49:

“I am quite ready to admit, that a man placed in the equilibrium described (namely, as perceiving nothing but hunger and thirst, a certain food and a certain drink, each equally distant from him) would die of hunger and thirst. If I am asked, whether such an one should not rather be considered an ass than a man; I answer, that I do not know, neither do I know how a man should be considered, who hangs himself, or how we should consider children, fools, madmen, etc.”

Spinoza’s suggestion that the equilibrium state is kin to such extra-rational states as childhood or madness could be seen as a throwing up of his hands – a narrowing of the anthropological interest, of the human all too human. But I take it as something other than a philosophical defeat; to me, this signals a moment in the history of philosophy:  a transformation of what used to the whole goal and morality of the sage’s exercise in refusing to want, in ascesis.
