In Wittgenstinian spirit the purpose of the article is therapeutic but I shall attempt to
prevent a common consequence of Wittgenstinian therapy, relapse. In a final section I shall
make three suggestions, which, taken together, might be the basis for a social science which
has no need of the dispositional account of tacit knowledge. I shall also suggest that if social
science requires a theoretical account of tacit processes of perception, learning, memory
and inference, the right approach is to use the sciences of memory, perception, and inference
– in other words, to integrate social science and cognitive psychology.
