Thought provoking but lapses into historiography/straight history at times (fair few examples whereby suggested meta philosophical principles have obtained/been deployed.) Concept of aporeitc reasoning useful to bear in mind (for Rescher a desiderata of future philosophy.) Section on Distinctions useful. Minus points: horrific solecisms abound. Typos galore. Wrongly spelled names, missing punctuation. Some sentences meaningless as consequence. Further, lazy wholesale cut and pasting leads to awful deja vu feeling (and tutting), the feeling that one has somehow turned the page only to go 60 pages back. A breezy read overall, with some interesting points to take away or build upon, but by golly it needed an editor's attention!
