I have come across an interesting talk by Caroline Williams which would be of interest and relevance to those following the topic of subjectivity, and political subjectivity in specific.
Professor Williams teaches at the School of Politics and International Relations at Queen Mary, University of London, and her main focus is on political theory, and as you will hear in this talk, the notion of political subjectivity.
If you find this talk interesting, then I would also suggest a recent related paper by her, titled, ‘Affective processes without a subject: Rethinking the relation between subjectivity and affect with Spinoza.’ This paper appears in the journal Subjectivity (Vol. 3, pp. 245-262).
I should also add that this talk was given at a conference titled “Spinoza and Bodies,” held in September 2009 at the University of Dundee. This and other presentations from that conference have been podcast online, you can find them here.
