The world always needs heretics to challenge the prevailing orthodoxies. We are lucky that we can be heretics today without any danger of being burned at the stake. But unfortunately i am an old heretic. Old heretics do not cut much ice. When you hear an old heretic talking, you can always say, “too bad he has lost his marbles”, and pass on. What the world needs is young heretics. I am hoping that one or two of you people in the audience may fill that role.
