I'm in the business of making medicine. Specifically, medicine for brain injuries. We (mk and I, along with a few other colleagues) have invented a medicine that we think may help brain injury victims heal more efficiently (stroke, traumatic injuries, etc). There's a significant problem with this medicine in that we don't really understand how it works (hence my favorite history of science fact about IC engines and the ideal gas law), at least not in any granular detail. This is difficult, because (a) it's hard to get funding to support it, and (b) the FDA has certain requirements that will be hard to meet some we can't explain exactly what e think we're doing. The whole medical system is set up around a reductive approach to biology. However, it has been proven by such geniuses as Wittgenstein and Koestler that reductionism is a fool's errand with regard to biology. There are things that cannot in principle be explained at the molecular level. Descriptivism fell out of favor in psychology long ago, but it still has a long way to fall in molecular biology.
