Do we have a moral duty to demolish the delusions of others? I suspect not. I know many people who, in my opinion, are deluded in their religious and political beliefs, but I steer clear of trying to persuade them to drop these beliefs. If at some point these delusions fail them and leave them in tears, it's not my fault. These are self-inflicted woes, right? I respect the right of others to fool themselves. Now, on a personal level, a girl has decided, without any encouragement on my part, that she would like me for a husband. Unasked, she showers me with gifts but reckons, I feel, that she will be getting them all back, anyway, once we are married. She is pleasant company. I enjoy the gifts. I don't lead her on with false promises. She is self-deluded. One of these days it is all going to end in tears. But I have no more responsibilty for those tears than I do if an acquaintance discovers that his religious sect is a load of bunkum and feels a miserable clown as a result,do I? Well, do I?
