AFTER ARGUING THAT LAUDAN’S ACCOUNT OF THE ROLE OF CONCEPTUAL CONSIDERATIONS IN THEORY APPRAISAL IS INADEQUATE AND UNSATISFYING IN A NUMBER OF RESPECTS, I SUGGEST SOME OF THE WAYS IN WHICH WE MIGHT MOVE TO DEVELOP AN ALTERNATIVE ACCOUNT. THIS ALTERNATIVE PRESUPPOSES A PROBLEM-SOLVING METHODOLOGY AND, UNLIKE THE LAUDANIAN APPROACH, AWARDS A CRUCIAL ROLE TO EMPIRICAL RESEARCH IN THE RESOLUTION OF THE CONCEPTUAL PROBLEMS TROUBLING A THEORY. THREE WAYS IN WHICH A THEORY MAY ENHANCE THE CONCEPTUAL RESOURCES WHICH IT SUPPLIES (...) FOR EMPIRICAL PROBLEM SOLVING ARE CONSIDERED: THE FINE-TUNING OF THEORETICAL CONCEPTS; THE APPROPRIATION OF THE CONCEPTUAL RESOURCES OF THEORIES IN OTHER DOMAINS; AND THE ACHIEVEMENT OF GREATER CONSILIENCE. REFERENCE IS MADE TO SEVERAL HISTORICAL CASES IN WHICH SUCH ENHANCEMENT ACTUALLY OCCURRED. (shrink)

In this paper I shall venture into an area with which I am not very familiar and in which I feel far from confident; namely into phenomenology. My main motive is not to get away from standard, boring, methodological questions like those of induction and demarcation; but the conviction that a phenomenological account of the empirical basis forms a necessary complement to Popper's falsificationism. According to the latter, a scientific theory is a synthetic and universal, hence unverifiable proposition. In fact, (...) in order to be technologically useful, a scientific hypothesis must refer to future states-of-affairs; it ought therefore to remain unverified. But in order to be empirical, a theory must bear some kind of relation to factual statements. According to Popper, such a relation can only be one of potential conflict. Thus a theory T will be termed scientific if and only if T is logically incompatible with a so-called basic statement b, where b is both empirically verifiable and empirically falsifiable. In other words: T is scientific if it entails ¬b; where b, hence also ¬b, is an empirically decidable proposition. (shrink)

This paper considers papers on conceptual analysis by Laudan (1981) and Whitt (1989) and relates them to three biochemical episodes: (1) the modern 'biochemical explanation' of acupuncture; (2) the chemio-osmotic hypothesis of oxidative phosphorylation; (3) the theory of the complete digestion of proteins in the gut. The advantages of including philosophical debate in chemical/biochemical undergraduate courses is then discussed.
