William Walker Atkinson,
Memory: How to Develop, Train, and Use It
(1919)
“ As we have said, this great subconscious region of the mind—this Memory region—may be thought of as a great record file, with an intricate system of indexes, and office boys whose business it is to file away the records; to index them; and to find them when needed. The records record only what we have impressed upon them by the attention, the degree of depth and clearness depending entirely upon the degree of attention which we bestowed upon the original impression. We can never expect to have the office boys of the memory bring up anything that they have not been given to file away. ”
