Pleas for pluralism

A few times during the exchange over the last few days I murmered that reflection on science casts doubt on a certain kind of single best language with monotonic (is that a word?) "interpretation" that appears to be taken for granted in doing metaphysics by many post-Lewisians. In part this doubt is due to a draft paper by Erik Curiel (against rigidity) I have been reading. For example, I first learned from Erik Curiel (now at LSE--he should not be implicated in my views) that according to the Standard Model, "the phenomena it treats can always be described in any of a competing number of ways, as there is a many-to-one relation between groups of particular particles and their fundamental interactions on the one hand and irreducible representations of symmetry groups on the other."
