It is not knowledge we lack

I've been in the grip of Sven Lindqvist's book on European barbarism. It's called 'Exterminate All The Brutes' and is a terrible, wrenching account of imperialism and racism through the centuries. He ends the book with this paragraph that I think is broadly applicable to life.

"You already know enough. So do I. It is not knowledge we lack. What is missing is the courage to understand what we know and draw conclusions."
