Regarding these artificial and fanciful systems, Kay says: "All such systems for the improvement of the memory belong to what we have considered the first or lowest form of it. They are for the most part based on light or foolish associations which have little foundation in nature, and are hence of little practical utility; and they do not tend to improve or strengthen the memory as a whole." Bacon says that these systems are "barren and useless," adding: "For immediately to repeat a multitude of names or words once repeated before, I esteem no more than rope-dancing, antic postures, and feats of activity; and, indeed, they are nearly the same things, the one being the abuse of the bodily as the other of the mental powers; and though they may cause admiration, they cannot be highly esteemed." And as another authority has said: "The systems of mnemonics as taught, are no better than crutches, useful to those who cannot walk, but impediments and hindrances to those who have the use of their limbs, and who only require to exercise them properly in order to have the full use of them." In this work, there shall be no attempt to teach any of these "trick systems" that the student may perform for the amusement of his friends. Instead, there is only the desire to aid in developing the power to receive impressions, to register them upon the memory, and readily to reproduce them at will, naturally and easily. The lines of natural mental action will be followed throughout. The idea of this work is not to teach how one may perform "feats" of memory; but, instead, to instruct in the intelligent and practical use of the memory in the affairs of every-day life and work. CHAPTER V. THE SUBCONSCIOUS RECORD-FILE. The old writers on the subject were wont to consider the memory as a separate faculty of the mind, but this idea disappeared before the advancing tide of knowledge which resulted in the acceptance of the conception now known as The New Psychology. This new conception recognizes the existence of a vast "out of consciousness" region of the mind, one phase of which is known as the subconscious mind, or the subconscious field of mental activities. In this field of mentation the activities of memory have their seat. A careful consideration of the subject brings the certainty that the entire work of the memory is performed in this subconscious region of the mind. Only when the subconscious record is represented to the conscious field, and recollection or remembrance results, does the memorized idea or impression emerge from the subconscious region. An understanding of this fact simplifies the entire subject of the memory, and enables us to perfect plans and methods whereby the memory may be developed, improved and trained, by means of the direction of the subconscious activities by the use of the conscious faculties and the will.
