 It is not obvious that these critiques are fair to proponents of a geometrical view. One might take their position not to be that a certain piece of geometrical structure (e.g., the Minkowski metric of STR) invariably constrains matter, whenever it is present in a theory, to manifest its symmetries (a claim which seems to be false, in light of the above cases). Instead, one might take their claim to be conditional: if one has matter which couples to this piece of geometrical structure in such-and-such a way, then that geometrical structure can explain why the laws have the such-and-such symmetries. In (Read, 2020a), the (arguably) straw man version of a geometrical view critiqued by Brown and Pooley is dubbed the ‘unqualified geometrical approach’, in contrast with this more nuanced and defensible version of the view, which is dubbed the ‘qualified geometrical approach’. (Brown might still reject the qualified geometrical approach on the grounds that it makes explanatory appeal to objects which violate the ‘action-reaction principle’, which states that every entity physical should both act on, and react to, other physical entities (Brown 2005, p. 140). If so, that this is the real reason for the rejection deserves to be flagged; moreover, it remains open whether the objection succeeds against the non-substantivalist versions of the geometrical view which are discussed below.)
