Phillip Sidney Horky is Lecturer in Classics at Durham University.

"Plato and Pythagoreanism is a fascinating, intelligent, and effective book... Horky provides a learned new account of mathematical Pythagoreanism and detects some of its traces in Platonic passages without succumbing to circularity. By applying novel approaches to an old question, Horky has provided scholarship with a very remarkable contribution." --Journal of the History of Philosophy

"This is an inspiring book, widening the view on the Pythagoreans and their concept of number. The material is perfectly organized." -Volker Peckhaus, Zentralblatt MATH

"This impressive work is crucial reading for students of early Pythagoreanism... Essential." --Choice

"Plato and Pythagoreanism is a most interesting study, from which I learned a good deal and derived much pleasure. Horky sets out here to investigate the nature and extent of the influence on Plato and the Academy of that tradition within early Pythagoreanism which may be termed 'mathematical.' Despite the sketchy nature of the evidence, Horky proves his argument sufficiently to make this an important contribution to scholarship."--John Dillon, Trinity College Dublin

"Horky's wide-ranging and meticulously researched Plato and Pythagoreanism provides an important contribution to our understanding of the doxographical traditions and the ongoing dialectic between the Greek philosophers of the fifth and fourth century BCE by engaging with some of the lesser known -- but no less interesting -- 'mathematical Pythagoreans' and systematically presenting their transformative influence on Plato's philosophy. This book deserves close attention from any student in ancient philosophy."--Mariska Leunissen, University of North Carolina at Chapel Hill

"Philip S. Horky's Plato and Pythagoreanism is both deeply insightful and actually pleasant to read ... it is a great success." -- Archai Journal: On the Origins of Western Thought
