Grounding Concepts: An Empirical Basis for Arithmetical Knowledge

Anyone with the slightest interest in the nature of mathematics should give [Jenkins] serious study. (James Robert Brown and James Davies. Philosophical Quarterly)

offers and original treatment of arithmetic that is clearly articulated and carefully argued... It is a book that should be read by anyone with an interest in these topics, and will repay careful study. (Albert Casullo, Mind)

I think highly of this book. Grounding Concepts adds a genuinely new option to the philosophical landscape. The central idea - that sense experience may be relevant to the epistemic status of concepts and thus play a non-evidential role in explaining knowledge - is both sensible and clever. The book is sophisticated and accessible, both extremely careful and extremely clear... Grounding Concepts is an excellent book. It provides a sophisticated and clear discussion of a difficult nest of issues in the philosophy of mathematics, epistemology, philosophy of mind, and metaphysics. By developing a new theoretical option, it makes a significant contribution to the literature on the epistemology of the a priori. Anyone interested in the epistemology of arithmetic or the nature of a priori knowledge would profit from reading it. (Joshua Schechter, Notre Dame Philosophical Reviews)
