Problems of Metaphysics and Psychology

People still want to know the answers to the questions addressed in Problems of Metaphysics and Psychology.
Of course, they want to know the answers to a great many more questions than are dealt with here, but a limit has to be drawn somewhere. The ones included here are: What is Psychology? What is Behaviorism? What is Science? What is Behavior? What is a Stimulus? What is Learning? What is Reinforcement? What is Motivation? What is Emotion? What is Instinct? and, What is Human Nature? No one of them was answered for all time earlier, and they are not likely to be answered now but reissuing the book at this time may remind those who are interested of what has gone before.
