How to reconcile the religious and ethical point of view regarding character with the scientific point of view is the problem to which Dr. Pierce addresses himself in this book. It is an attempt to give a provisional, but intelligible, account of how ideals act in the world, preserving both the ethical value of the notions of God, freedom, and immortality, and the validity of scientific laws, so that a scientific psychology of character as the expression of purpose may be eventually developed.
