It is the want of something like this in the acquisition of truth by books, which renders that kind of knowledge in general of so little practical benefit. The truths and facts learned while attending school, are too often received as mere abstractions, without reference to their uses, or to the personal application of those uses to the circumstances of the child or his companions. Events daily occur in which the pupil's knowledge might be of important service;--but the benefits to be derived from it not having been taught, and the method of applying the facts which he has acquired by reading not having been explained,--the knowledge and its uses are seldom seen together, and the practical benefit of the teaching is accordingly lost. This at once accounts for the very remarkable circumstance, that children, and not unfrequently adults also, derive far more benefit from the scanty knowledge which they have gleaned by observation and experience, than from the many thousands of highly useful facts which have again and again been pressed upon their notice by reading and study. In almost every case Nature prompts us, as we have seen, to turn to our own benefit the knowledge which she has imparted; but as the mode of teaching reading, which is the _artificial_ method of acquiring information, often overlooks the use we are to make of it, we remain satisfied with the knowledge itself, and do not think of its application. To illustrate this fact in some measure, let us suppose a basket of filberts set down for the use of a company of boys, and that one of them tries to crack the shells with his front teeth. He fails. But he sees his companions put the nuts farther back in the mouth, and succeed. Does he lose his share, by continuing to misapply the lever-power provided for him by Nature?--No indeed. He, by a single observation, at once draws and applies the lesson;--he immediately cracks his nuts as readily as his companions, and he continues to do so all his lifetime after. But the same boy may have, that very forenoon, been reading a treatise on the power of the lever, and might read it again and again without considering himself at all interested in the matter, or thinking it probable that he ever would. His reading, without the application we are here recommending, would never have led him to perceive the slightest similarity between the fulcrum of the lever, and the insertion of his jaw; or any connection between the lesson of the school, and the employment of the parlour:--But that would.
