"Assimilative Memory; or, How to Attend and Never Forget" by A. Loisette is a guide on memory enhancement techniques written in the late 19th century. The book introduces a systematic approach to memory training, positing that memory is not a separate faculty but is deeply integrated into every mental action. This work emphasizes learning through active thought rather than rote memorization, detailing methods to develop habits of attention and thinking to aid remembrance. At the start of the book, Prof. A. Loisette lays out his foundational concepts of memory and learning. He identifies the two crucial stages of memory: first impressions and their revival, explaining how each memory is a product of concrete experiences and their later recollection. Loisette further explains his “three laws of thinking” pertaining to inclusion, exclusion, and concurrence, which are essential tools for improving memory. These concepts aim to help the reader understand how to methodically link ideas, enhance observation, and ultimately improve one's ability to recall information.
