"Out of... average boys, if they are well brought up, come some of the most useful men to society, and sometimes great men; for the apparent dulness or slowness of some boys is only apparent: they do not apprehend quickly, because they see difficulties which sharper boys do not see, but when they emerge from the hide-bound state, they go on at a great rate, soberly and steadily. These boys become the men whom we trust... with weighty matters."
