Even now, I believe that to know how is useless if we do not know why. And there are too many who forbid us to ask.
There are no things man was not meant to know. There are, perhaps, things man is too dumb to figure out, but that's a different problem.
Because all books are forbidden when a country turns to terror. The scaffolds on the corners, the list of things you may not read. These things always go together.
