This course aims to take seriously Ludwig Wittgenstein's claim that his chief contribution was methodological, by seeking to elucidate - and to give practical facility with - his most important later tools, moves, and methods for clarifying our concepts and disentangling our confusions. To do this we must study a range of Wittgenstein's later works, and get to grips with such widely used (and misused) Wittgensteinian terms of art as 'language game', 'form of life', and 'surface/depth grammar'. Most importantly, the course involves practice in actually applying these tools and methods to our own research problems (philosophical or otherwise).
