Gregory Gillette is a member of the Mathematics Department at the Pennsylvania State University’s Greater Allegheny campus. He holds a Ph.D. in Fluid and Solid Mechanics from the Catholic University of America, School of Engineering. Dr. Gillette’s scholarly interests include studies of traditional perspectives on the mathematical sciences and on the pursuit of mathematics as a liberal discipline. He is a member of the American Mathematical Society and the Association for Symbolic Logic, and is the author of the book *Isaac Newton’s Philosophy of Sacred Space and Sacred Time: An Essay on the History of an Idea*, also published by the Edwin Mellen Press.

This book provides an analysis of the concepts of space and time in the thought and writings of Sir Isaac Newton, attempting to illustrate his portrayal of both of these as sacred, not merely material entities. This book offers an interesting contribution to current debates concerning the relationship between science and religion, and will appeal to those who study the philosophy of religion, theology, and the history of science.

Isaac Barrow largely responsible for that preservation and promulgation of the Euclidean tradition which, on the one hand, invigorated the physical science and mathematics of Newton and others, and on the other hand, allowed for an ongoing engagement with classical Greek mathematics, which continues down to the present day. Barrow’s philosophy of mathematics remains relevant to many key issues still at the forefront of modern philosophies of mathematics.
