A couple of quotes on hope.

“Well, it’s important to have hope that something can be done at some level to protect what’s of value in the world, and I think something can be done, But such hope must be informed by a realistic understanding of human beings as they are.

There’s a type of hope now which I think is very harmful, which is essentially a form of blocking out reality because it’s too difficult to contemplate. Now, I think , that’s a much more hopeless view.” – John Gray

“Hope is only where despair is. Something truly new-beginning happens only when you are in such deep shit that, within the existing coordinates you can find no way out, and then, in order to survive you have to invent something new. The magic is to turn a desperate situation into something new.” – Slavoj Zizek
