"We have to learn to accept it and see both sides of it and try to make it better. I am worried about our tendency to adopt a fatalistic, pessimistic perception of history.

... I know that you can't say when leaders raise this kind of pessimism that it is all just invented. It is not all invented, and you would be stupid if you did not look ((at it)) with open eyes. But it is a major risk that you will not notice that you become enslaved by this pessimism in a way that will paralyze you from understanding that you can shape it.
The world is full of risks, but that doesn't mean that you don't have a responsibility to do something about it — within your limits and the limits of realism — and avoid self-fulfilling prophecies that are extremely dangerous here."
