This article is the lecture of my research of H.Wallon which was taken at the Hokkaido University on the 30 in september 1999. There are tow ideas in my study of H.Wallon, that is, 1) the idea of distinction between emotion and feeling 2) the idea of continuity between education and formation , and of possibility about the establishment of new educational science in the period of social crisis. Now my research is going on to Wallon's "L'Enfant turbulent",especially to "the stage of emotion" in it. However in his discovery of this stage, there were many psychiatrists' efforts from 18th Century to the begining of 20th Century, for example, these of Charcot, Bernheim, Ribot, Fere, Binet, and Janet, which were these of finding "unconsience" or "subconscience" by other way than that of G.Freud. I hope that my reseach of H. Wallon is toward the combination of his action in life, his tought, and his personality. And also I hope to make clear not only the fact of Wallons' accomplished works, and his unaccoplished works even if wishing to reach his purpose, but also the fact of the unthinkable themes by himelf. I think there are many themes which include the dissolvable in H.Wallon's reseach for example, critical study of the proseses of "semiotisation" especially in regard to the "theory of mind",and new aspect of psychanalystic study on langege and mind, so on. But we should not research H.Wallon's thought in its fragments and by only pragmatic utility in the situation of today, because it makes his thought ineffectual for developping his essential and fundamental truth. On the contrary we should discover the basis of his historical thought and establish the truely historical psychology and pedagogy of H.Wallon in every respect.
