A study of the Bergsonian notion of <sensibility> in his early years : focusing on his three lectures on psychology given at the end of 19th century

In another paper I already pointed out that Henri Bergson (1859-1941), a French philosopher, in his later years argues on <sensibility> from his particular point of view. In this paper I aim to examine his notion of <sensibility> in his early years, focusing on three lectures on Psychology given at the end of 19th century. Except for The Two Sources of Morality and Religion (1932), Bergson scarcely refers to <sensibility> in the works published in his lifetime. And furthermore, based on Bergson's will, it has been forbidden for a long time to publish the reports of his lectures given at several lycées, École Normale Supérieure and Collège de France. Therefore, it has been extremely difficult to guess when, how and under what circumstances Bergson elaborates his own idea of <sensibility>. Since the end of 20th century, however, the reports of Bergson's lectures are published one after another. These new documents will enable us to get over the difficulty mentioned above. This paper forms a part of such an investigation.
