  Most of the articles over the subsequent 28 years of the JPL belong to the first of these four categories. But the description with which this list begins is not particularly illuminating: why should these particular topics be of interest to philosophers? Their most important shared feature is a sense that despite successes in formalizing areas of mathematical logic, the scope of logic remained severely limited. There are unsolved problems in formalizing the nonmathematical sciences that seem to require thinking through new and different logical issues (quantum logic and the logic of induction, for instance). The remaining topics cover a part, at least, of the even more pressing problems involved in extending logical theory to nonscientific reasoning. The dominant goal, then, of philosophical logic is the extension of logical methods to nonmathematical reasoning domains. This goal has a theoretical dimension if (as many philosophical logicians seem to feel) it requires reworking and extending logical formalisms.
