Bertrand Russell was a very wise man. In this 1959 recording he talks about what truths he would like future generations to understand.
His two key points, if grasped and honored by humanity, would change everything:
1) What are the facts and what is the truth that the facts bear out?
2) Love is wise. Hatred is foolish. In this world, which is getting more and more inter-connected, we have to learn to tolerate each other.
As I say, a very wise man. With an accent and speaking style that makes him utterly convincing.
