"A nation should always be healthily rebellious; but the king or prime minister has yet to be found who will make trouble by cultivating that side of the national spirit. A child should begin to assert itself early, and shift for itself more and more not only in washing and dressing itself, but in opinions and conduct; yet as nothing is so exasperating and so unlovable as an uppish child, it is useless to expect parents and schoolmasters to inculcate this uppishness. Such unamiable precepts as Always contradict an authoritative statement, Always return a blow, Never lose a chance of a good fight, When you are scolded for a mistake ask the person who scolds you whether he or she supposes you did it on purpose, and follow the question with a blow or an insult or some other unmistakable expression of resentment, Remember that the progress of the world depends on your knowing better than your elders, are just as important as those of The Sermon on the Mount; but no one has yet seen them written up in letters of gold in a schoolroom or nursery."
