Bergson's "Matter and Memory," a ladder between perception and sensation

Bergson's "Matter and Memory," a ladder between perception and sensation
Before Bergson enters the big question of "memory," he carefully proceeds to the arrangement of outer perception and inner sensation. Perception is an image that is on the side of the world and has a spatial extent, while sensation is an intensity-only phenomenon that occurs inside the body and has no extent. If this distinction is blurred, it is easy to fall into a circular argument that regards memory as an image in the brain, so it was first necessary to clarify the position of the two. However, the mere juxtaposition of outer perception and inner sensation does not establish the meaning of experience. Education" or "training," as Bergson suggests, refers to the process of weaving through experience the connection between visual patterns and internal bodily responses. Whether a scene is perceived as dangerous or nostalgic is determined by the accumulation of bodily sensations and past experiences, and this connection is the function of memory. Memory is conceived not as a
projection chamber in the brain, but as a history of relationships formed by the repetition of modalities linking perception and sensation. Thus, the rigorous depiction of the arrangement of perception and sensation is not a prelude to memory, but the very foundation of mnemonic theory, and Bergson is attempting to redefine memory by inspecting the ladder between the world and the body.
