from AN ESSAY CONCERNING HUMAN UNDERSTANDING

"In all things, therefore, where we have clear evidence from our ideas, and those principles of knowledge I have above mentioned, reason is the proper judge; and revelation, though it may, in consenting with it, confirm its dictates, yet cannot in such cases invalidate its decrees: nor can we be obliged, where we have the clear and evident sentience of reason, to quit it for the contrary opinion, under a pretence that it is matter of faith: which can have no authority against the plain and clear dictates of reason."

"Revelation in matters where reason cannot judge, or but probably, ought to be hearkened to. First, Whatever proposition is revealed, of whose truth our mind, by its natural faculties and notions, cannot judge, that is purely matter of faith, and above reason."

"Truth, then, seems to me, in the proper import of the word, to signify nothing but the joining or separating of Signs, as the Things signified by them do agree or disagree one with another. The joining or separating of signs here meant, is what by another name we call proposition. So that truth properly belongs only to propositions: whereof there are two sorts, viz. mental and verbal; as there are two sorts of signs commonly made use of, viz. ideas and words."

"Our knowledge of our own existence is intuitive. As for our own existence, we perceive it so plainly and so certainly, that it neither needs nor is capable of any proof... I think, I reason, I feel pleasure and pain: can any of these be more evident to me than my own existence?... For if I know I feel pain, it is evident I have as certain perception of my own existence, as of the existence of the pain I feel: or if I know I doubt, I have as certain perception of the existence of the thing doubting, as of that thought which I call doubt. Experience then convinces us, that we have an intuitive knowledge of our own existence, and an internal infallible perception that we are. In every act of sensation, reasoning, or thinking, we are conscious to ourselves of our own being; and, in this matter, come not short of the highest degree of certainty."

To show, therefore, that we are capable of knowing, i.e. being certain that there is a God, and how we may come by this certainty, I think we need go no further than ourselves, and that undoubted knowledge we have of our own existence... For man knows that he himself exists... If any one pretends to be so sceptical as to deny his own existence, (for really to doubt of it is manifestly impossible,) let him for me enjoy his beloved happiness of being nothing, until hunger or some other pain convince him of the contrary... He knows also that nothing cannot produce a being; therefore something must have existed from eternity... Next, it is evident, that what had its being and beginning from another, must also have all that which is in and belongs to its being from another too. All the powers it has must be owing to and received from the same source. This eternal source, then, of all being must also be the source and original of all power; and so this eternal Being must be also the most powerful... And most knowing. Again, a man finds in himself perception and knowledge. We have then got one step further; and we are certain now that there is not only some being, but some knowing, intelligent being in the world. There was a time, then, when there was no knowing being, and when knowledge began to be; or else there has been also a knowing being from eternity...And therefore God."

"All men are liable to error; and most men are, in many points, by passion or interest, under temptation to it."


from SECOND TREATISE ON GOVERNMENT

"Though I have said above... That all men by Nature are equal, I cannot be supposed to understand all sorts of Equality: Age or Virtue may give Men a just Precedency: Excellency of Parts and Merit may place others above the common level: Birth may subject some, and Alliance or Benefits others, to pay an Observance to those to whom Nature, Gratitude or other Respects may have made it due; and yet all this consists with the Equality which all men are in, in respect of Jurisdiction or Dominion one over another, which was the Equality I there spoke of... being that equal Right that every Man hath, to his natural Freedom, without being subjected to the Will or Authority of any other Man."

"The Legislative cannot transfer the Power of Making Laws to any other hands. For it being but a delegated Power from the People, they who have it, cannot pass it over to others. The People alone can appoint the Form of the Commonwealth, which is by Constituting the Legislative, and appointing in whose hands that shall be."

"...whenever the Legislators endeavour to take away, and destroy the Property of the People, or to reduce them to Slavery under Arbitrary Power, they put themselves into a state of War with the People, who are thereupon absolved from any farther Obedience ... [Power then] devolves to the People, who have a Right to resume their original Liberty, and, by the Establishment of a new Legislative (such as they shall think fit) provide for their own Safety and Security, which is the end for which they are in Society."


from A LETTER CONCERNING TOLERATION

"Now, I appeal to the consciences of those that persecute, torment, destroy, and kill other men upon pretence of religion, whether they do it out of friendship and kindness towards them or no?... I say, if all this be done merely to make men Christians and procure their salvation, why then do they suffer whoredom, fraud, malice and such-like enormities, which (according to the Apostle) manifestly relish of heathenish corruption, to predominate so much and abound amongst their flocks and people?"
