The republication of David Bloor's Knowledge and Social Imagery is evidence of the continuing interest and importance of the work but also provides the clearest evidence of the shortcomings of the enterprise. The new Afterword of Bloor's second edition addresses criticisms of the Strong Programme, but the theses which Bloor now defends are substantially weaker claims than the iconoclastic tenets of the original manifesto. Moreover, in a related strategy, Bloor asserts that criticisms made since 1975 have given him no reason (...) to modify the original text, but there are judicious alterations which are revealing. These unacknowledged alterations are documented here. Bloor's Strong Programme was founded on the diametrical opposition between his causal sociological approach and the allegedly a?causal rationalist, psychologist or ?teleological? approach. However, once it was shown that the teleological position is not the straw?man he represented it to be, Bloor's diametrical opposition left him no retreat. Just as Bloor weakens the original claims of the Strong Programme to make them appear compatible with cognitive science, so he eradicates the suggestion that the opposing teleological position was ever as absurd as he had portrayed it. The common rationale of these independent tactics leaves little question about their purpose ? and their futility. (shrink)

This article considers the `Strong Programme' account of scientific knowledge from a fresh perspective. It argues that insufficient attention has been paid to the Strong Programme's monistic intent, that is, its aim to unify considerations of instrumental adequacy and social interests in explanations of the development of scientific knowledge. Although sharing the judgment of many critics that the Strong Programme approach is flawed, the article diverges from standard criticisms by suggesting that the best alternative is not a dualistic framework but (...) a more adequate monistic approach. Key Words: Strong Programme • interests • monism • finitism • classification. (shrink)
