text: I have a few favorites, but one in the same vein as yours:\n\n"It is better to keep your mouth closed and be thought a fool than to open it and remove all doubt."\n--Attributed to Samuel Lonhorn Clements (Mark Twain), althoug perhaps in error.\n\nAlbert Einstein is another person with some great quotes:\n\n"Reality is merely an illusion, albeit a very persistent one."\n\n"Great spirits have always encountered violent opposition from mediocre minds."\n\n\nI got some other good answers when I asked the same question a few days ago.
