Human and animal behavior can be shown to follow the laws of physics. In Psychology in a Physical World, Orzeck observes that humans and animals constantly try to predict their own behavior, following the essence of habit and, therefore, Newton's First Law of Motion. The author reveals that the Second and Third Laws are also part of everyday behavior. These three laws together with the law of non-contradiction and the law of isomorphism are shown to explain a great deal of human behavior.
