If you direct your whole thought to work itself, none of the things which invade eyes or ears will reach the mind.
QuintilianMinds that are stupid and incapable of science are in the order of nature to be regarded as monsters and other extraordinary phenomena; minds of this sort are rare. Hence I conclude that there are great resources to be found in children, which are suffered to vanish with their years. It is evident, therefore, that it is not of nature, but of our own negligence, we ought to complain.
Quintilian
