Thanks Mr.Alex for replying. I appreciate it.

One of the results of the illness was that he completely lost confidence in his beliefs. At some point afterwards, he decided to reverse any spontaneous response of his. The moment he feels a desire to say something, he will now say the opposite.

Ok. If that's what really happened, how would we know about it? I don't think that person would go and tell other people what he thinks he's doing, because he wants to lie and he doesn't want other people to know that he is.

Am I right??
