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.

John LockeIt is one thing to show a man that he is in an error, and another to put him in possession of the truth.
John LockeThere cannot any one moral rule be proposed whereof a man may not justly demand a reason. Every man has a property in his own person. This nobody has any right to but himself. The people cannot delegate to government the power to do anything which would be unlawful for them to do themselves.
