Exploring the development of the modern multiple personality movement, Hacking found its roots in the sciences of memory that emerged in the late 19th century. The focus of his arguments is on process in which multiple personalities, the new kind of people, emerged through "looping effect", that is, interaction between sciences of memory and people. Through following his arguments on this looping effect, this paper is to consider the way to describe the relation between human experiences and human sciences.
