"The heresy of heresies was common sense." —George Orwell, 1984. This book is a defense of common-sense realism, which is the greatest heresy of our time. Following common-sense philosophers like Thomas Aquinas, G. K. Chesterton, C. S. Lewis, Dallas Willard, and J. P. Moreland, this book defends a common-sense vision of reality within the Christian tradition. Mosteller shows how common-sense realism is more reasonable than the materialist, idealist, pragmatist, existentialist, and relativist spirits of our age. It maintains that we can know the nature of reality through common-sense experience and that this knowledge has profound implication for living the good life and being a good person.
