 There are two paths leading from reduction to ground. First, reductive interpretations of paradigmatic dependence claims may inspire a reconstruction of reduction in terms of ground. Reductionists about the mental argue that mental states, like pain, reduce to certain physiological states and are, hence, identical to the latter. Eliminativists argue that mental states or properties just do not exist. Anti-reductionists maintain that pains exist and are different from corresponding physiological states. Some naturalists employ various notions of dependence to capture the priority of the natural while acknowledging a plurality of layers of reality. The debate thus centered on questions of existence and, often, various dependence relations, ranging from emergence to ruthless reduction. It appears, then, that the reductionist about the mental maintains that the mental reductively depends on the physiological.
