My way of looking at self-delusion is accepting the defence mechanisms where they belong, and that may be different for different people.
But the wear for all should be as well concern for understanding one's own purpose for the discussions in the long run.
How does knowledge itself get better for the conscience, ethical tension for the needs we are after, common sense of pride (good point; a fantasy may come out of PRIDE and then a self-delusion takes over) can be be made evident by the specific site's demand like this one, and the personally real
one's you were brought into the interest for what you containing in an idea.
I believe this is for a rigorous person at this point. Most of us are on the religious debate site. But the other part of fantasy is of great value too.
Maybe someone else can explain that. A reflection on a good book, something one saw, and the fantasizing concerning very externality. There exists I believe a free release onto the World beyond one's own confines. The political left find imagination for how and who they've associated with; the political right find values for what they intently really do understand about the individuals in community.
Self-delusion may be a failure to catch one's fantasies concerning the World at large and stick to Them. :help:
