This course explores theory and theorisation - what they are, what they contribute to our understanding of the world, how they are deployed within anthropology and sociology - both historically and in the present - and what their limitations can be. The broad aim of the course is to foster critical thinking about the way theories are constructed and used, drawing on a range of both 'canonical' and 'non-canonical' examples - including in particular from the so-called 'Global South' - in order to provide a more decentred and global perspective.
