Can anyone help me track down a remark from Hume?
When I first read Hume, I remember either the book or a section ending with a sceptical critique of our notion of self and concluded in effect that it was impossible to make this track with any reliability. After observing this, Hume remarked (or so I recall) that he did not know what kind of philosophy was possible in the light of this conclusion.
However, I simply cannot find this remark anywhere. I have scoured the Enquiries and searched the Treatise; the discussion concerning doubt of the self can be found in the section entitled Personal Identity in the Treatise, and echoed again in the Appendix. But not the remark about what kind of philosophy was possible in the light of doubt of the self.
If anyone knows where this remark originates, and can help me track it to its source, I would be most grateful.
