Abstract
Singer's study of the technical problems of Santayana's systematic thought will not satisfy his friends nor his detractors. Her reduction of Santayana's Lucretian materialism to epiphenomenalism will seem inadequate to the former. The latter may see Santayana as merely technically inept. While Singer does not claim to offer a comprehensive study of Santayana's thought, her theses " that Santayana was a naturalist and a materialist in the same sense and on the same grounds throughout; that despite even radical changes in terminology his 'later' ontology is a development of, and not inconsistent with, his 'earlier' philosophy; and that, nevertheless, from the start his materialism was touched with ambiguity", do need a comprehensive understanding of Santayana's materialism. The "ambiguities" of his materialism and his social theory in Dominations and Powers derive from the ontological complexities of his realms of Being. Santayana plays with the perspectives possible from each realm and Singer sometimes misses his viewpoint. Santayana's challenge to the liberalism of democracy is indeed based on his a-teleological materialism. Singer's study does draw attention to the analogy of the individual to the state implicit in Santayana's philosophy; she offers refutations of M. K. Munitz's theory of "early and "late" Santayana and W. K. Dennes' interpretation of Santayana's materialism.--A. T.
