The most important book I have ever read is the Holy Bible.

This is the second most important book I have ever read. It changed my life in that it taught me that to fail to stand up for the truth is unthinkable, because if we fail to stand up for the truth, the unthinkable will happen.

The Holocaust: A History of the Jews of Europe During the Second World War

The unthinkable is happening right now. Stand up.
