The Problem of Good questions a materialist age which reduces reality to that studied by the physical sciences. According to materialism, all reality, including thought, consists of impersonal forces that have no purpose and are neither good nor bad. This book attempts to show the reasonableness of rejecting materialism, and to affirm that thought and purpose are real. Importantly, we can hope and work for that which constitutes the good. If there is a problem of evil leading some to reject the notion of God, there is likewise the problem of good, which can lead to an acceptance of the idea of God and purpose in the universe. This work is readable even without formal training in philosophy. It invites the reader to a vision of the world which embraces purpose, the good, and motivation to work a better world.
