A pragmatist approach to the problem of knowledge in health psychology

The multiplicity of forms of health-related knowledge, including biomedical knowledge, lay knowledge and critical constructionist knowledge, raises challenges for health researchers. On one hand, there is a demand for a pluralist acceptance of the variety of health-related knowledge. On the other, the need to improve health calls for action, and thus for choices between opposing forms of knowledge. The present article proposes a pragmatist approach to this epistemological problem. According to pragmatism, knowledge is a tool for action and as such it should be evaluated according to whether it serves our desired interests. We identify implications for research methodology and the choice of research goals

A Modal View of the Semantics of Theoretical Sentences

Modal logic has been applied in many different areas, as reasoning about time, knowledge and belief, necessity and possibility, to mention only some examples. In the present paper, an attempt is made to use modal logic to account for the semantics of theoretical sentences in scientific language. Theoretical sentences have been studied extensively since the work of Ramsey and Carnap. The present attempt at a modal analysis is motivated by there being several intended interpretations of the theoretical terms once these terms are introduced through the axioms of a theory
