So the chapters in this book are: the Distinctiveness of Philosophical Reasoning, the Infinite Regress, the Two-Worlds Argument, Self-Refutation, the Verifiability Argument, Excluded Opposites and Paradigm Cases and Allocation to Categories. Don't ask me to elaborate on any of these because the author writes about them in such a convoluted way that I can't honestly say that I absorbed anything from this book. Maybe this book is just targeted specifically for academic philosophers, I don't know. Would not recommend.
