The Reason Series is a 5-Part comprehensive, age-appropriate program designed to provide high-school and college age students the evidence they need to know that God and science are not at odds with each other. This easy-to-use workbook for the Reason Series includes summaries of units and some additional information for further student inquiry. It also includes a password for students to log onto an online forum (for discussions and Q&A).

Based on the award winning book, New Proofs for the Existence of God: Contributions of Contemporary Physics and Philosophy, by Fr. Robert J. Spitzer, S.J., Ph.D., The Reason Series follows college freshman Joe as he learns to defend his faith from his atheistic roommate Tyler with the help of physics and philosophy grad students Dan and Alana.
