NATURALISM AND THE PARADOX OF REVISABILITY

Abstract:  This paper examines the paradox of revisability. This paradox was proposed by Jerrold Katz as a problem for Quinean naturalised epistemology. Katz employs diagonalisation to demonstrate what he takes to be an inconsistency in the constitutive principles of Quine's epistemology. Specifically, the problem seems to rest with the principle of universal revisability which states that no statement is immune to revision. In this paper it is argued that although there is something odd about employing universal revisability to revise itself, there is nothing paradoxical about this. At least, there is no paradox along the lines suggested by Katz.     

THE PARADOX OF INQUIRY IN AUGUSTINE'S CONFESSIONS

Abstract: The Confessions recounts Augustine's successful search for God. But Augustine worries that one cannot search for God if one does not already know God. That version of the paradox of inquiry dominates and structures Confessions 1–10. I draw connections between the dramatic opening lines of book 1 and the climactic discussion in book 10.26–38 and argue that the latter discussion contains Augustine's resolution of the paradox of inquiry as it applies to the special case of searching for God. I claim that he develops a model, relying on the universal human experience of joy and truth, that identifies a starting point that (1) is common to all human beings, (2) is sufficient for guiding a successful search for God, and (3) avoids commitment to recollection of experiences prior to birth. The model is crucial to Augustine's rejection of traditional Platonist views about recollection.     

A PARADOX IN THE PERCEPTION OF LUMINANCE GRADIENTS. II

The first paper in this series was a study on a brightness paradox in the perception of luminance gradients in space. This study tests the hypothesis that an inducing field of higher or lower luminance having a luminance acceleration in space is a necessary condition for the paradox to appear. A magnitude estimation and a constant-sum method were used. The main result was a falsification of the hypothesis. A luminance acceleration across the inducing field was not necessary but it enhanced the paradox. The results are discussed in relation to theories on neural inhibition.
