Samuel C. Wheeler III

This essay shows that Derrida's discussion of "Differance," is remarkably parallel to Plato's discussion of Difference in the Parmenides. Plato's presentation of "Parmenides'" discussion of generation from a One which Is is a version of Derrida's preconceptual spacing. Derrida's implicit reference to Plato both interprets Plato and explains the obscure features of "Differance." Derrida's paradoxical remarks about Differance are very like what Plato implies about Difference. Derrida's Differance addresses the puzzle that concepts are required to construct the beings in a plurality of objects, but concepts cannot differentiate unless there is already a plurality of objects. Plato's version of the same problem is a notational variant of Derrida's Husserlian dilemma. Derrida, following Davidson, is not only skeptical about the project of founding metaphysics on simple entities, but also holds that necessity has no foundation in the "world." Plato, on the other hand, retains the idea that necessity has an objective basis in the self-evident truths of mereology.

Much contemporary metaphysics, moved by an apparent necessity to take reality to consist of given beings and properties, presents us with what appear to be deep problems requiring radical changes in the common sense conception of persons and the world. Contemporary meta-ethics ignores questions about logical form and formulates questions in ways that make the possibility of correct value judgments mysterious. In this book, Wheeler argues that given a Davidsonian understanding of truth, predication, and interpretation, and given a relativised version of Aristotelian essentialism compatible with Davidson’s basic thinking, many metaphysical problems are not very deep. Likewise, many philosophers' claims that common sense needs to be modified are unfounded. He argues further that a proper consideration of questions of logical form clarifies and illuminates meta-ethical questions. Although the analyses and arguments he gives are often at odds with those at which Davidson arrived, they apply the central Davidsonian insights about semantics, understanding, and interpretation
