Many years ago, C.B. Martin drew our attention to the possibility of ‘finkish’ dispositions: dispositions which, if put to the test would not be manifested, but rather would disappear. Thus if x if finkishly disposed to give response r to stimulus s, it is not so that if x were subjected to stimulus r, x would give response z; so finkish dispositions afford a counter‐example to the simplest conditional analysis of dispositions. Martin went on to suggest that finkish dispositions required (...) a theory of primitive causal powers; there, I think, he was mistaken. All that they require is an improved conditional analysis, and this improved analysis can be built upon whatever treatments of properties and of laws we may favour on other grounds. (shrink)

Originally published in 1982, the aim of this book is a controversial one - to refute, by the most rigorous philosophical methods, physical realism and to develop and defend in its place a version of phenomenalism. Physical realism here refers to the thesis that the physical world is an ingredient of ultimate reality, where ultimate reality is the totality of those entities and facts which are not logically sustained by anything else. Thus, in arguing against physical realism, the author sets (...) out to establish that ultimate reality is wholly non-physical. The crucial elements in this argument are the topic-neutrality of physical description and the relationship between physical geometry and natural law. The version of phenomenalism advanced by John Foster develops out of this refutation of physical realism. Its central claim is that the physical world is the logical creation of the natural constraints on human sense-experience. This phenomenalist perspective assumes that there is some form of time in which human experience occurs but which is logically prior to the physical world, and Foster explores in detail the nature of this pre-physical time and its relation to time as a framework for physical events. This book was a major contribution to contemporary philosophical thinking at the time. (shrink)
