 As a consequence, reduction is taken to have the “structural features of identity”, such as reflexivity and symmetry, as Trogdon maintains (Trogdon 2013, similarly: Audi 2012), but also intensionality. Then, it is not clear how reduction could possibly exhibit the structural features of ground – irreflexivity, asymmetry, and hyper-intensionality. (This observation seems to parallel the tension between supervenience and dependence noted above.) Philosophers have reacted in different ways. Some take these observations at face value and conclude that reduction is distinct from ground (Audi 2012, Trogdon 2013). Others have argued that it would be short-sighted to construe reduction in this way. From Identity Reduction, it simply does not follow that reduction has the structural features of identity. Recall the puzzle of reduction discussed above: Although reduction requires identity, identity is not sufficient for reduction. In fact, if a reduces to b, it follows, by the asymmetry of reduction, that b does not reduce to a. For this and similary reasons, it has been suggested that reduction generates hyper-intensional contexts, and that reduction statements are sensitive to the modes of presentation expressed by the terms flanking the reduction predicate (Jenkins 2011, van Riel 2013, 2014). On this view, reduction may turn out to be a variant of ground.
