Abstract

The last pair of nonevidential tests for explanation sets that I shall consider come under the headings of simplicity and economy, the latter being, I suppose, what Quine and Ullian call “modesty”, that is, the test that “other things being equal, the less story the better”.1 One translation of this slogan is that if everything is equal, the more economical a system is in its ontology, the better it is. Unfortunately, However, economy and specially simplicity cover a bewilderingly large variety of proposed test, unlike the sorts of test previously considered. Furthermore, because of this superabundance of competitors, a comprehensive and detailed examination of the available alternatives coupled with a well-reasoned defense of one or more tests is beyond the scope of this chapter. I shall try, however, to describe the leading candidates of each sort briefly, indicate quickly my reasons for rejecting or accepting them, and propose, with a modicum of defense, a new test of each sort which avoids the problems of its predecessors.
