Abstract: Hope is ubiquitous: family members express hope that we find love and happiness, politicians call for hope in response to tragedies, and optimists urge people to keep their hopes up. We also tell ourselves to maintain hope, to find it, or in darker moments, to give it up. We hope for frivolous things, too. But what is hope? Can hope be rational or irrational? Is hope valuable? Is it ever dangerous? This essay reviews recent important answers to these questions with the goal of better understanding hope.
Comment: An introduction to the epistemology and ethics of hope.
