Martin and Pfeifer claim ‘that the most typical characterizations of intentionality’ proposed by philosophers are satisfied by physical dispositions. If that is correct, we must conclude either, as they do and as Mumford (this volume) does, that the philosophers are wrong and intentionality is something else or, as I do, that intentionality is what the philosophers say it is, in which case it is the mark, not of the mental, but of the dispositional; the intentionality of a disposition consists in (...) its being directed towards its future manifestations. Mumford objects that the notion of directedness is obscure and cannot in the light of Martin’s electro‐fink argument be elucidated by reference to what would happen if the conditions for its manifestation are satisfied. But Martin‘s argument rests on the mistaken assumption that causal conditionals, of which dispositional ascriptions are an instance, are of the form ‘If p then q’. (shrink)

A wide-ranging study of the central concepts in epistemology - belief, truth and knowledge. Professor Armstrong offers a dispositional account of general beliefs and of knowledge of general propositions. Belief about particular matters of fact are described as structures in the mind of the believer which represent or 'map' reality, while general beliefs are dispositions to extend the 'map' or introduce casual relations between portions of the map according to general rules. 'Knowledge' denotes the reliability of such beliefs as representations (...) of reality. Within this framework Professor Armstrong offers a distinctive account of many of the main questions in general epistemology - the relations between beliefs and language, the notions of proposition, concept and idea, the analysis of truth, the varieties of knowledge, and the way in which beleifs and knowledge are supported by reasons. The book as a whole if offered as a contribution to a naturalistic account of man. (shrink)

1. Causal knowledge is an indispensable element in science. Causal assertions are embedded in both the results and the procedures of scientific investigation. 2. It is therefore worthwhile to investigate the meaning of causal statements and the ways in which we can arrive at causal knowledge.
