The subset-of-causal-relations account as stated is compatible with a determinate species being conjunctively analyzable into a genus and differentia, each associated with a proper subset of the powers of the species
A distinguishing feature (such as an internal organ or a capacity like inhaling/exhaling air) that characterizes groups of animals.
genus(Aristotle's metaphysical classification scheme in the Metaphysics)
A kind that must be differentiated by some differentia that falls outside that genus.
powers(Distinguished from sensible qualities to argue that causal necessity is never directly perceived.)
The underlying causal capacities of bodies by which they produce effects, held to be entirely unknown and unobservable.
subset-of-causal-relations account(Philosophy of properties and metaphysics of determination)
An account of the generic/determinable universal relation on which a generic or determinable type is associated with a proper subset of the causal relations associated with each of its specific or determinate types
A subset-of-causal-relations account of generic/determinable universals promisingly accommodates many features of determination, for reasons similar to those attaching to powers-based accounts, below. It also ensures the metaphysical irreducibility of a generic/determinable type to any specific/determinate type, by the principle of the indiscernibility of identicals (if \(G\) has only a proper subset of causal relations of \(S\), \(G\) cannot be identified with \(S\)); and if this proper subset
