He seems to me to keep saying that "pleasure is pleasure", a pathe.
My mind is still open on the issue of the meaning of desire in this context, but I think all of these questions turn on subtle issues of definitions, and in the end all feelings of pleasure have the common denominator of feeling pleasurable, but I do not believe that the feeling is identical except in that strict definitional (conceptual) sense. And that's where I think we have one of these intersections of the limits of conceptual reasoning from totally capturing every aspect of reality.
