Abundant Properties
On an abundant conception of properties, properties serve as semantic values for most predicates and property names. Abundance is central to Dispositional Pluralism. Dispositional Pluralism is compatible with different theories of the metaphysics of properties. According to universalism (realism) properties are universals that are wholly present wherever they are instantiated. According to extensionalism (class nominalism) properties are sets of objects. According to trope theory, properties are sets of particular property instances, or tropes. In any case, properties correspond to sets of objects. Abundance is preferable to sparsity—the view that only an elite minority of sets of particulars correspond to properties. On most sparse views, the “real” properties are largely unknown. Consequently, sparse properties are unfit for the roles properties are posited to play: They rarely serve as the semantic values of predicates; they do not explain familiar causal powers; and it is not clear how they explain apparent similarities.
