Abstract

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
