WHO WILL FILL THE VOID LEFT BY CHRISTOPHER HITCHENS?

Christopher Hitchens died in december 2011. I hope one would agree that like him or hate him, he provoked conversation and thought on many profound subjectsfacing our society. I do not see anyone filling that void. There are so many subjects that without review will neither improve or evolve. We can chose to ignore issues, never discuss them, but they don’t go away.
The Greeks, 18th century man, seemed to have been moments in history where discussion was considered a sign of a cultured man.
