Reason, 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.
John LockeFor a man's property is not at all secure, though there be good and equitable laws to set the bounds of it, between him and his fellow subjects, if he who commands those subjects, have power to take from any private man, what part he pleases of his property, and use and dispose of it as he thinks good.
John LockeDefects and weakness in men's understandings, as well as other faculties, come from want of a right use of their own minds; I am apt to think, the fault is generally mislaid upon nature, and there is often a complaint of want of parts, when the fault lies in want of a due improvement of them.
