On what grounds do you think so?
gpt
Why on the simple ground that a man _cannot_ change any opinion until he is convinced that it is wrong, and that he inevitably must, and actually does, change his opinion on the instant that he is so convinced; and that in virtue, not of his will, but of the constitution of his mind. Some men's minds are of such a nature--they take such a limited and weak grasp of things--that they cannot be easily convinced. Others are so powerful that they readily seize upon truth when it is presented to them; but in either case, the instant the point of conviction is reached the mind is changed. Pride may indeed prevent the admission of this change, but it takes place, as I have said, inevitably.
