Show Summary Details


The remaining chapters are devoted to various philosophical applications of ranking theory. The first goal is to understand natural modalities as covertly epistemological modalities by a kind of projectivistic strategy on the basis of ranking theory, which has already proved how well it accounts for epistemological modalities. The first of those natural modalities, lawlikeness, is treated in this chapter. A review of the difficulties with that notion concludes that laws are best understood via their inductive behavior. The study of that behavior arrives, after thorough argument, at the notion of a subjective (deterministic) law that is simply the ranking-theoretic analogue of the notion of a Bernoulli measure or statistical law. It turns out then that de Finetti’s philosophy of probability, incarnated in his representation theorem, can be fully carried over to the deterministic side. Thus, the confirmation of deterministic laws works in essentially the same way as that of statistical laws. The chapter concludes with some observations about the apriority of the belief in lawfulness, i.e., in the uniformity of nature.
