From whence it is obvious to conclude that, since our Faculties are not fitted to penetrate into the internal Fabrick and real Essences of Bodies; but yet plainly discover to us the Being of a GOD, and the Knowledge of our selves, enough to lead us into a full and clear discovery of our Duty, and great Concernment, it will become us, as rational Creatures, to imploy those Faculties we have about what they are most adapted to, and follow the direction of Nature, where it seems to point us out the way.
John LockeLong discourses, and philosophical readings, at best, amaze and confound, but do not instruct children. When I say, therefore, that they must be treated as rational creatures, I mean that you must make them sensible, by the mildness of your carriage, and in the composure even in the correction of them, that what you do is reasonable in you, and useful and necessary for them; and that it is not out of caprichio, passion or fancy, that you command or forbid them any thing.
John LockeTill a man can judge whether they be truths or not, his understanding is but little improved, and thus men of much reading, though greatly learned, but may be little knowing.
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 LockeAny single man must judge for himself whether circumstances warrant obedience or resistance to the commands of the civil magistrate; we are all qualified, entitled, and morally obliged to evaluate the conduct of our rulers. This political judgment, moreover, is not simply or primarily a right, but like self-preservation, a duty to God. As such it is a judgment that men cannot part with according to the God of Nature. It is the first and foremost of our inalienable rights without which we can preserve no other.
