A […] parallel is afforded by the closely kindred art of writing, which adds to and enhances all the advantages belonging to the art of speech, and is as indispensable to the highest culture as is speech to the lower; but like speech, it came into being by a process in which the only conscious motive was communication; all its superior uses followed in the train of that, and were unthought of until experience disclosed them; indeed, they are even yet unthought of by the greater part of those who derive advantage from them.
