If we have any role at all, I think it’s the role of optimism, not blind or stupid optimism, but the kind which is meaningful, one that is rather close to that notion of the world which is not perfect, but which can be improved. In other words, we don’t just sit and hope that things will work out; we have a role to play to make that come about.
