Abstract This paper deals with two fundamental assumptions of the Strong programme in the sociology of knowledge and the theoretical (im) possibility of their co?existence with the general relativist tendency of this programme. The first assumption is the realist thesis introduced into the Strong programme through the materialist presupposition that sense experience is reliable and humans are able to learn about the regularities of the non?social world in order to survive. The second assumption is the causal principle. Arguments developed in (...) this paper lead to the conclusion that neither realism nor causalism can be reconciled with relativism. In both cases inconsistency is brought about by a tension between scientific perspective and relativism, between an external approach aiming at objective, universal, and causal explanation of what is studied, on the one hand, and the internal, relativist and reflexive, hermeneutical understanding of the human, on the other hand. The belief that the sociology of knowledge can be at the same time scientific, like the natural sciences, and relativist, like certain philosophies but not the natural sciences, is not sufficiently justified in the Strong programme.

Both the sociology of knowledge and the philosophy of science are centrally concerned with the succession of scientific beliefs. In case studies of scientific debates, however, the emphasis tends to be placed on the outcome of disputes. This paper proposes that attention should instead be focused on the process of debate: that is, on scientific argumentation. It is shown how such a focus circumvents many traditional epistemological problems concerning the truth-status of scientific knowledge. By reference to the consensus conception of (...) truth, it is claimed that scientific arguments can be studied naturalistically whilst still honouring the orientation towards truth exhibited by scientists. Finally, the paper offers a brief résumé of recent studies indicating how this naturalistic study of scientific argumentation can be developed through the sociology of language. (shrink)
