Children should not be suffer'd to lose the consideration of human nature in the shufflings of outward conditions. The more they have, the better hum… - John Locke

The toleration of those that differ from others in matters of religion is so agreeable to the Gospel of Jesus Christ, and to the genuine reason of mankind, that it seems monstrous for men to be so blind as not to perceive the necessity and advantage of it in so clear a light. I will not here tax the pride and ambition of some, the passion and uncharitable zeal of others. These are faults from which human affairs can perhaps scarce ever be perfectly freed; but yet such as nobody will bear the plain imputation of, without covering them with some specious colour; and so pretend to commendation, whilst they are carried away by their own irregular passions. But, however, that some may not colour their spirit of persecution and unchristian cruelty with a pretence of care of the public weal and observation of the laws; and that others, under pretence of religion, may not seek impunity for their libertinism and licentiousness; in a word, that none may impose either upon himself or others, by the pretences of loyalty and obedience to the prince, or of tenderness and sincerity in the worship of God; I esteem it above all things necessary to distinguish exactly the business of civil government from that of religion and to settle the just bounds that lie between the one and the other. If this be not done, there can be no end put to the controversies that will be always arising between those that have, or at least pretend to have, on the one side, a concernment for the interest of men's souls, and, on the other side, a care of the commonwealth.

The old question will be asked in this matter of prerogative, But who shall be judge when this power is made a right use of ? 1 answer: between an executive power in being, with such a prerogative, and a legislative that depends upon his will for their convening, there can be no judge on earth; as there can be none between the legislative and the people, should either the executive, or the legislative, when they have got the power in their hands, design, or go about to enslave or destroy them. The people have no other remedy in this, as in all other cases where they have no judge on earth, but to appeal to heaven: for the rulers, in such attempts, exercising a power the people never put into their hands, (who can never be supposed to consent that any body should rule over them for their harm) do that which they have not a right to do. And where the body of the people, or any single man, is deprived of their right, or is under the exercise of a power without right, and have no appeal on earth, then they have a liberty to appeal to heaven, whenever they judge the cause of sufficient moment. And therefore, though the people cannot be judge, so as to have, by the constitution of that society, any superior power, to determine and give effective sentence in the case; yet they have, by a law antecedent and paramount to all positive laws of men, reserved that ultimate determination to themselves which belongs to all mankind, where there lies no appeal on earth, viz. to judge, whether they have just cause to make their appeal to heaven. And this judgment they cannot part with, it being out of a man's power so to submit himself to another, as to give him a liberty to destroy him; God and nature never allowing a man so to abandon himself, as to neglect his own preservation: and since he cannot take away his own life, neither can he give another power to take it. Nor let any one think, this lays a perpetual foundation for disorder; for this operates not, till the inconveniency is so great, that the majority feel it, and are weary of it, and find a necessity to have it amended. But this the executive power, or wise princes, never need come in the danger of: and it is the thing, of all others, they have most need to avoid, as of all others the most perilous.

For where is the man that has incontestable evidence of the truth of all that he holds, or of the falsehood of all he condemns; or can say that he has examined to the bottom all his own, or other men's opinions? The necessity of believing without knowledge, nay often upon very slight grounds, in this fleeting state of action and blindness we are in, should make us more busy and careful to inform ourselves than constrain others.
