"The past is a country we can never return to, but whose borders we are always crossing."

The first step in liquidating a people is to erase its memory. Destroy its books, its culture, its history. Then have somebody write new books, manufacture a new culture, invent a new history. Before long the nation will begin to forget what it is and what it was. The world around it will forget even faster.

The pursuit of mathematical truth is a never-ending adventure.
