A classification of the forms of memory into portative, analytical, and assimilative, given in Latham’s book on the “Action of Examinations,” is helpful in determining the relation of memory to thinking.
The portative memory simply conveys matter. “Its only aim, like that of a carrier, is to deliver the parcel as it was received.” It is the form of memory that enables some people to carry the contents of entire volumes in their minds, sometimes in the very words, oftener in ideas only. The rhapsodists in ancient Greece who could repeat entire books of Homer are examples in point. Some men of superior talent have possessed this power in an eminent degree. Macaulay, on a voyage across the Irish Channel, rehearsed from memory an entire book of Virgil’s “Æneid.” It is the kind of memory that shines at examinations and excites the envy of persons less gifted with powers of retention. It may easily be degraded into a slave, doing work which should be performed by higher mental powers. Hence it has been appropriately styled the Cinderella faculty of the mind. Like the girl in the story, it may be abused dreadfully by having all sorts of useless drudgery heaped upon it. To require a child to learn the five thousand isolated facts formerly scattered through treatises on geography was an exercise as useless as the picking of the lentils which were poured into the ashes to give Cinderella something to do, and, unfortunately, there is no bird from fairyland to assist in the accomplishment of the task.
Much as we may admire the power of Thomas Fuller, who could repeat five hundred unrelated words in foreign languages after hearing them twice, it is an accomplishment not worth acquiring. As an accomplishment it recalls the king to whom a man exhibited his skill in throwing a pea so that it would stick on the end of a pin,—a feat acquired after years of patient practice. The man hoped to get a valuable present for his exhibition of skill. The king ordered a bag of pease to be given him, saying that it was all his accomplishment was worth.
There is no end of warnings as to the possible evil effects of a good memory upon the power to think,—warnings that a teacher may take to heart with advantage to himself and others.
