For 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 LockeWhoever uses force without Right ... puts himself into a state of War with those, against whom he uses it, and in that state all former Ties are canceled, all other Rights cease, and every one has a Right to defend himself, and to resist the Aggressor.
John LockeA father would do well, as his son grows up, and is capable of it, to talk familiarly with him; nay, ask his advice, and consult with him about those things wherein he has any knowledge or understanding. By this, the father will gain two things, both of great moment. The sooner you treat him as a man, the sooner he will begin to be one; and if you admit him into serious discourses sometimes with you, you will insensibly raise his mind above the usual amusements of youth, and those trifling occupations which it is commonly wasted in.
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.

John LockeEvery Man being conscious to himself, That he thinks, and that which his Mind is employ'd about whilst thinking, being the Ideas, that are there, 'tis past doubt, that Men have in their Minds several Ideas, such as are those expressed by the words, Whiteness, Hardness, Sweetness, Thinking, Motion, Man, Elephant, Army, Drunkenness, and others: It is in the first place then to be inquired, How he comes by them? I know it is a received Doctrine, That Men have native Ideas, and original Characters stamped upon their Minds, in their very first Being.
