Inuring children gently to suffer some degrees of pain without shrinking, is a way to gain firmness to their minds, and lay a foundation for courage and resolution in the future part of their lives.

It is evident the mind knows not things immediately, but only by the intervention of the ideas it has of them.

This makes it Lawful for a Man to Kill a Thief, who has not in the least hurt him, nor declared any design upon his life, any farther then by the use of Force, so to get him in his Power, as to take away his Money, or what he pleases from him.: because using force, where he has no Right, to get me into his Power, let his pretense be what it will, I have no reason to purpose that he, who would take away my Liberty, would not when he had me in his Power, take away every thing else. And therefore it is Lawful for me to treat him, as one who has put himself into a State of War with me, I.e. kill him if I can; for to that hazard does he justly expose himself, whoever introduces a State of War, and is Aggressor in it.
