is successfully gained, all the previous steps have been homologated and confirmed; whereas, whenever this crowning operation is awanting, all the preceding labour of the pupil becomes useless and vain, his knowledge gradually melts from the memory, and is ultimately lost. The _fourth_, or supplementary process in this educational course as conducted by Nature, we found to consist in the training of her pupils to an ability to communicate with ease and fluency to others the knowledge and experience which they themselves had acquired.--This ability, as we have shewn, is not instinctive, but is in every instance the result of education. It is not always the accompaniment of great mental capacity; nor is it always at the command of those who have acquired extensive knowledge. Persons highly gifted in both respects, are often greatly deficient in readiness of utterance, and freedom of speech. On careful investigation we have seen, that it is attained only by practice, and by one simple exercise of the mental powers, in which the thoughts are engaged with one set of ideas, at the same moment that the voice is giving expression to others. This faculty has been found to be eminently social and benevolent, and intended, not so much for the benefit of the individual himself as for the benefit of society. Nature, accordingly, constrains mankind to do homage to eloquence when it is employed for others, or for the public;--but strongly induces them to look with pity or contempt on the person who is always speaking of or for himself. These facts accordingly have led us to the important conclusion, that learning and the possession of knowledge are not intended merely for the person himself, but for the good of society; and therefore, that education in every community ought to be conducted in such a manner, that the attainments of each individual in it, shall either directly or indirectly benefit the whole.
