Having now defined, or rather described, what we mean by _a good memory_, we may consider how the memory should be cultivated. In children, as well as in men, the strength of that habit, or perhaps of that power of the mind which associates ideas together, varies considerably. It is probable, that this difference may depend sometimes upon organization. A child who is born with any defect in his eyes, cannot possibly have the same pleasure in objects of sight, which those enjoy who have strong eyes: ideas associated with these external objects, are, therefore, not associated with pleasure, and, consequently, they are not recollected with any sensations of pleasure. An ingenious writer[51] supposes, that all the difference of capacity amongst men ultimately depends on their original power of feeling pleasure or pain, and their consequent different habits of attention.
When there is any defect in a child's organization, we must have recourse to physics, and not to metaphysics; but even among children, who are apparently in the full possession of all their senses, we see very different degrees of vivacity: those who have most vivacity, seldom take delight in repeating their ideas; they are more pleased with novelty than prone to habit. Those children who are deficient in vivacity, are much disposed to the easy indolent pleasure of repetition; it costs them less exertion to say or do the same thing over again, than to attempt any thing new; they are uniformly good subjects to habit, because novelty has no charms to seduce their attention.
The education of the memory in these two classes of children, ought not to be the same. Those who are disposed to repetition, should not be indulged in it, because it will increase their indolence; they should be excited by praise, by example, by sympathy, and by all the strongest motives that we can employ. Their interest in every thing around them must by all means be increased: when they show eagerness about any thing, no matter what it is, we may then exercise their memory upon that subject with some hopes of success. It is of importance that they should succeed in their first trials, otherwise they will be discouraged from repeating their attempts, and they will distrust their own memory in future. The fear of not remembering, will occupy, and agitate, and weaken their minds; they should, therefore, be animated by hope. If they fail, at all events let them not be reproached; the mortification they naturally feel, is sufficient: nor should they be left to dwell upon their disappointment; they should have a fresh and easier trial given to them, that they may recover their own self-complacency as expeditiously as possible. It may be said, that there are children of such a sluggish temperament, that they feel no pleasure in success, and no mortification in perceiving their own mental deficiencies. There are few children of this description; scarcely any, perhaps, whose defects have not been increased by education. Exertion has been made so painful to them, that at length they have sunk into apathy, or submitted in despair to the eternal punishment of shame.
