"Today, more than ever, it is important for people not to close their eyes to the danger of evil that lurks within them. And because unfortunately this evil is very real, psychology must insist on its reality and reject any characterization that considers it insignificant or non-existent. Psychology is an empirical science that deals with realities. As a psychologist, I have neither the inclination nor the authority to get involved with the metaphysical. The only thing I have to do is to fight when the metaphysical appropriates the experience and interprets it in a way that is not empirically justified."
