4. From the nature of this great fundamental principle in mental cultivation, as consisting in the reiteration of ideas, and not of words, we have a key by which we can satisfactorily explain the remarkable, and hitherto unaccountable fact, that many persons who, in youth and at school, have been ranked among the dullest scholars, have afterwards become the greatest men. An active mind, in exact proportion to its vigour, will powerfully struggle against the unnatural thraldom of mere mechanical verbal exercises. The mind in a healthful state will not be satisfied with words, which are but the medium of ideas, because ideas alone are the natural food of the mind. Till the powers of the mind, therefore, are sufficiently enfeebled by time and perseverance, it will struggle with its fetters, and it will be repressed only by coercion. Minds naturally weak, or gradually subdued, may and do submit to this artificial bondage,--this unnatural drudgery; but the vigorous and powerful mind, under favourable circumstances, spurns the trammels, and continues to struggle on. It may be a protracted warfare,--but it must at last come to a close; and it is not till the pupil has emerged from this mental dungeon, and has had these galling fetters fairly knocked off, that the natural elasticity and strength of his mind find themselves at freedom, with sufficient room and liberty to act. The impetus then received, and the delight in the mental independence then felt, have frequently led to the brightest results. Hence it is, that the reputed dunce of the school, has not unfrequently become the ornament of the senate. Lastly, we would remark, that from the facts here enumerated, we derive a good test by which to try every new exercise proposed for training the young, and for cultivating the powers of the mind. If the exercise recommended compels the child to active thought,--to the voluntary exercise of his own mind upon useful ideas,--that exercise, whatever be its form, will, to that extent at least, be beneficial. And if, at the same time, it can be associated with the acquisition of knowledge, with the application of knowledge, or with the ready communication of knowledge,--all of which, as we have seen, are concomitants in Nature's process,--it will, in an equal degree, be valuable and worthy of adoption. But if, on the contrary, the exercise may be performed without the necessity of voluntary thought, or the reiteration of ideas by the mind, however plausible or imposing it may appear, it is next to certain, that although such an exercise may be sufficiently burdensome to the child, and cause much labour and anxiety to the teacher, it will most assuredly be at least useless, if not injurious.
