After reading two thirds of this work, I have come to the conclusion that I do not have a problem with 'Difference', the 'Problem of Difference' does not exist for me. I do have a problem though with the few names here which supposedly tackled this problem. Chief among them Husserl, possibly the most overrated thinker of 20th century after his lunatic protege. The man is a ball of confusion, going round and round positing layers and fluxes and intending forms which are supposed to clarify problems whose source are the very chimerical schema he is constantly revising to avoid an infinite regress or many. Bell, as another review here mentions, makes clever connections between concerns of phenomenologists and those of analytical thinkers like Kripke and Frege which highlight just how little they added to resolving those in comparison. Phenomenology has always been parasitic on findings in psychology (particularly Gestalt psychology) and neuroscience nowadays, and as much as they bracket things they make no discovery which was not made without abandoning the 'natural attitude'.
I skipped the brief Deleuze bits in the end of the book. They seemed skimpy which is best when considering the work of an imposture
