The narration; it is bad.
Above all I'd ask that the pronunciation throughout the book be consistent. Next, I'd ask that he use the standard pronunciations for the names of philosophers and the technical philosophical terms.
For example, in the first hour and a half Leibniz gets both "Lieb-nis", "Leeeb-nis" and "Lib-nis."
Why wasn't this kind of thing checked?
