This essay contains a partial exploration of some key concepts associated with the epistemology of realist philosophies of science. It shows that neither reference nor approximate truth will do the explanatory jobs that realists expect of them. Equally, several widely-held realist theses about the nature of inter-theoretic relations and scientific progress are scrutinized and found wanting. Finally, it is argued that the history of science, far from confirming scientific realism, decisively confutes several extant versions of avowedly 'naturalistic' forms of scientific (...) realism.

1. I shall attempt in this paper to give a rounded, if schematic, account of the concept of probability. My central concern will be to clarify the sense in which law-like statements (including 'statistical' law-like statements) are made probable by observational data which, in a sense equally demanding analysis, 'accord' with them.

The current sociotechnical enterprise known as technology assessment (TA) is examined. Applying Skolimowski's analysis of epistemic possibility, the two foci of TA activities, impact analysis and policy analysis are shown to involve different logical and methodological forms. Impact analysis is shown to follow the logic of applied science while policy analysis involves the logic of technological design. Methodological implications of this distinction are isolated. Areas requiring conceptual clarification internal to TA practice are identified and limitations of the overall approach are (...) articulated. (shrink)
