The term "human nature" should, according to the symposium organizer, imply both its positive side or humanitarian love, and negative side or aggression-destructive tendency, cruelty, and jealousy, etc. By recognizing human nature as such, we shall be able to have deeper insight and better understanding both on ourselves and other people. In the twentieth century, after the two World Wars, human nature has been discussed from the viewpoint of "war and peace", but it should be discussed now in relation to the great development of technology as well as the social systems and its structures. The first speaker, M. Tatara mentioned from the point of view of psychoanalysis the malformation and recovery of human nature. He mainly stressed on Erikson's point of view, but pointed out the fact that the recovery also depended on social situations to some extents. The second speaker M. Murayama, a Rogerian introduced the characteristics of C. Rogers' point of view on human nature. The third speaker H. Kawai, a Jungian, grasped hmnan nature with two opposite poles-logos and pathos-and at present he thinks that human nature should be broadly considered in relation to the highly developed technology. He believes that to understand human nature as a whole it should be based not only on organized logical approach, but also on phenomenological one faithful to facts.
