I’ve seen this attributed both to Frank Herbert and David Brin but I originally heard it from Herbert so that’s who gets my credit. He followed the quote by advising that you keep an eye on any who seek power. Do good people go into positions of power and come out as bad people or were they bad all along? I dunno, I just change the letters.
I don’t have a semicolon, by the way; that there is an upside-down period laid upon a comma. Booyah. Also I think that this might be the limit to how many characters I can get on this sign so I apologize to people trying to read it while driving.
