The books which help you most are those which make you think the most.
The books that the world calls immoral are the books that show the world its own shame.
Don’t join the book burners. Do not think you are going to conceal thoughts by concealing evidence that they ever existed.
Books won’t stay banned. They won’t burn. Ideas won’t go to jail. In the long run of history, the censor and the inquisitor have always lost.
