Feyerabend and others have been defending for some time the thesis that even observation sentences depend for their meanings on the thegries in which they play a role. According to the most radical version of this thesis, if two theories contain incompatible theoretical statements, then even if the observation terms and sentences associated with the two theories are the same, these terms and sentencesmeansomething different, according as they are associated with one theory or the other. This claim has made it (...) hard to see how, on this view, any two theories could be said to compete, or be incompatible, or be comparable on the basis of observation.The whole dispute over this claim seems highly suspect to begin with. For look at the philosophical terms in which it is couched. On the one hand there is the notion of the “meaning” of a term or sentence, whose status as a useful tool of philosophical analysis has been in serious question for the past two or three decades.

A critical analysis of Woodger's work on formal logic in biology, especially genetics, reveals that the claim for the value of such methods in genetics is misplaced.

This paper presents an analysis of the structure of contemporary sociological knowledge in terms of a theory of scientific discourse. The concept of 'discourse' is introduced as a theoretical refinement of the concept of 'paradigm' and is applied to the classes of knowledge claims of the natural and social sciences. It is concluded that general modes of scientific discourse are definable in terms of their vertical differentiation from everyday discourse, while particular modes of sociological discourse are additionally definable in terms (...) of their horizontal differentiation. A classification is then proposed which identifies three modes of sociological discourse: natural, technical and formal. (shrink)
