The Indians , whom we call barbarous, observe much more decency and civility in their discourses and conversation, giving one another a fair silent hearing till they have quite done; and then answering them calmly, and without noise or passion. And if it be not so in this civiliz'd part of the world, we must impute it to a neglect in education, which has not yet reform'd this antient piece of barbarity amongst us.

John LockeReason, if consulted with, would advise, that their children's time should be spent in acquiring what might be useful to them when they come to be men, rather than to have their heads stuff'd with a deal of trash, a great part whereof they usually never do ('tis certain they never need to) think on again as long as they live: and so much of it as does stick by them they are only the worse for.
