“I’d rather reject the terms optimistic and pessimistic. They suggest a calculation of how things are going to evolve, and if it’s going to evolve in the way you want, you’re optimistic. That has very little to do with despair and hope. Hope is not a form of guarantee, it’s a form of energy, and very frequently that energy is strongest in circumstances that are very dark.”
