Bergson identifies multiple forms of memory throughout his work. In Matter and Memory, Bergson considers memory from the perspectives of both psychology and metaphysics, and he describes what we might refer to as contraction memory, perception memory, habit memory, recollection memory, and pure memory. Further, in subsequent works, Bergson discusses at least two additional forms of memory – namely, a memory of the present and a non-intellectual memory of the will. However, it is often not clear how these different forms (...) of memory relate to one another. With the aim of providing an overview of Bergson's philosophy of memory that can also serve as a point of entry to his philosophy as a whole, this article explores the different senses and forms of memory that Bergson describes, paying special attention to how they are distinct from one another and how they are unified. It is my intention to show that, although these various senses and forms of memory are different from one another , they are also continuous and unified insofar as they are equivalent to different tones of one's mental life and to different tensions of one duration.
