The reason why any one refuses his assent to your opinion, or his aid to your benevolent design, is in you: he refuses to accept you as a bringer of truth, because, though you think you have it, he feels that you have it not. You have not given him the authentic sign.
It is open to every man to choose the direction of his striving; and also every man may draw comfort from Lessing's fine saying, that the search for truth is more precious than its possession.
The very essence of truth is plainness and brightness; the darkness and crookedness is our own. The wisdom of God created understanding, fit and proportionable to truth, the object and end of it, as the eye to the thing visible. If our understanding have a film of ignorance over it, or be blear with gazing on other false glitterings, what is that to truth?
