An interesting Planet Money podcast (link goes to the associated post) about how much a pelican is worth. That is, how much should BP have to pay, per pelican, for wrongfully killing pelicans? How do you estimate dollar damages in cases where there aren’t markets that could give you a reasonable ‘market valuation’ of some degraded environmental condition, and in which laypeople are sort of torn between ‘infinitely valuable’ and ‘I’d pay a dollar’ responses to a survey question? It turns out that the answer is ‘a pelican for a pelican’, at least according to the federal agency responsible for solving this problem. If BP killed 500 pelicans, they have to pay whatever it costs to save 500 other pelicans, or pay for a pelican nursery that will raise 500 pelicans, or something of the sort.
I have a somewhat more than passing interest in the history of lex talionis, so I’m struck by this reversion to what is generally regarded as an intolerably primitive, retributivist formula. An eye for an eye, a pelican for a pelican. Of course, the first thing to note about it is that here it isn’t functioning in a retributivist spirit at all. Quite the contrary, it’s a utilitarian kludge for handling a case in which calculating a util seems too fraught.
Note the oddity of the fact that at no point in the podcast does anyone ask how much a pelican is worth to a pelican [to the pelican that happens to be that pelican]. Suppose someone proposed that it is impossible to value human life in a wrongful death suit, say, because we’ve outlawed slavery (just as we’ve outlawed traffic in migratory birds). That would be a funny sort of argument. But it does show up how our intuitions about environmental value are an odd mix of absolutism (nature is infinitely valuable) and instrumentalism (nature is valuable for us).
Maybe that means we are just monstrously inconsiderate of [better: conflicted about] animal rights in our typical thinking about environmental damage. I actually kinda think so [most days], but I don’t think there’s much chance of a serious paradigm shift that would go deep enough to alter that. So, setting aside that possibility, and moving back down the scale to more practical questions, it seems to me that there might be a way to tweak the ‘pelican for a pelican’ lex talionis principle, to make it more flexible – to make the currency of pelicans more fluidly exchangeable and money-like, in a way that the average American might find intuitive and, if not satisfying, then at least as not-unsatisfying as any formula is likely to be.
