Hume’s thesis

In one of his most famous passages, Hume writes:

This remark admits of various interpretations: metaphysical and phenomenal, strong and weak. Here I want to defend a strong phenomenal version of Hume’s view. I want to argue that there is no phenomenal quality corresponding to the subject of experience – no phenomenal I.

This topic has been much discussed by philosophers, and, like Hume, most tend to rely on intuitions, introspective reports, and contestable transcendental arguments. My review will begin with Descartes, but I will be more interested in assessing lines of research that treat the phenomenal I as a topic for empirical inquiry. There have been a number of recent attempts to identify a subject of experience using the techniques of contemporary brain science. I will consider some of the more promising proposals and argue that they come up short in important ways.
