 Note that while the traditional approach to divine simplicity is in terms of identity, this approach is open to what Dolezal (2011, 136–144) calls the “harmonist challenge” according to which, on one variation, that of Immink (1987), the divine attributes are not identical but necessarily equivalent. Dolezal also counts Swinburne (1994) among the harmonists. Harmonism will not be discussed further in this entry. See Dolezal (2011) for competent critique of harmonism and for an overall excellent defense of DDS.
