Book excerpt: In Truth Without Paradox, David Johnson purports to solve several of the traditional problems of metaphysics, pertaining to truth, logic, similitude, morality, and God. In the first chapter, he argues (in three independent ways) against the general acceptability of the schema 'if p then it is true that p', claiming thereby to resolve the paradoxes of the liar and of the sorites. In the second chapter, he clarifies what was (and what was not) settled by Quine about "truth by convention." In the third chapter, he attempts to shed light on the obscure notion of "sameness," or "uniformity," especially in its application to inductive extrapolation and to the grue paradox. In the fourth chapter, he purports to solve the "Is/Ought" problem of moral philosophy. The fifth and final chapter, which will be of interest to philosophers of religion, contains what the author calls an historical proof of the existence of God, based on (among other things) a resolution of the lottery paradox.
