Writing about pragmatism, the (irr-) rationality of practice, scepticism and the self, in a word: about the relation of theory (thinking) and practice. Interested therefore in topics such as a non-scientisti naturalism, the role of history, performativity, power and individualization. Some important authors are Dewey, Cavell, Wittgenstein, Foucault, Kant. See also my personal website www.joergvolbers.de.
