A set of properties P realize a set of properties M just in case the instantiation of the properties in P is sufficient for the instantiation of of the properties in M. See also physicalism, token identity theory, supervenience, and functionalism

In the philosophy of mind, the notion of realization is typically employed to express the theses of physicalism (all properties are realized by physical properties) and multiple realizability (disparate sets of physical properties can realize the same mental properties).
