The concept of “tacit knowledge” as the means by which individuals interpret the “rules” of social interaction occupies a central role in all the major contemporary theories of action and social structure. The major reference point for social theorists is Wittgenstein's celebrated discussion of rule-following in the Philosophical Investigations. Focusing on Giddens' incorporation of tacit knowledge and rules into his “theory of structuration”, I argue that Wittgenstein's later work is steadfastly set against the “latent cognitivism” inherent in the idea of (...) tacit knowledge and tacit rules. I also argue that the idea of tacit knowledge and tacit rules is either incoherent or explanatorily vacuous. (shrink)

In general, in our ordinary life, we manage to make the difference between “strange” behavior and error or extravagant beliefs. The question is here to know how we do so, and against what background. There are also specialized contexts for evaluating whether certain types of behavior or discourse are normal or abnormal: courts of law and psychiatric hospitals are two examples. In these contexts, judgments are formed against a background of technical or scientific knowledge, but they also result from epistemic (...) means of evaluation that are similar to habitual ones. The paper seeks to highlight this similarity with respect to recognizing mental disturbance. Starting from Wittgenstein’s On Certainty, it attempts at extending it by drawing on notions of reciprocal perspectives and of judgments of incongruity. It documents its investigation by analyzing sequences from Malek Bensmail’s documentary, Aliénations, which examines the treatment of mental suffering in contemporary Algeria. (shrink)
