If one puts forward an idea to a true Englishman—always a rash thing to do—he never dreams of considering whether the idea is right or wrong. The only thing he considers of any importance is whether one believes it oneself. Now, the value of an idea has nothing whatsoever to do with the sincerity of the man who expresses it.

Context

“Lord Henry stroked his pointed brown beard and tapped the toe of his patent-leather boot with a tasselled ebony cane. "How English you are Basil! That is the second time you have made that observation. If one puts forward an idea to a true Englishman—always a rash thing to do—he never dreams of considering whether the idea is right or wrong. The only thing he considers of any importance is whether one believes it oneself. Now, the value of an idea has nothing whatsoever to do with the sincerity of the man who expresses it. Indeed, the probabilities are that the more insincere the man is, the more purely intellectual will the idea be, as in that case it will not be coloured by either his wants, his desires, or his prejudices.” source
