Abstract
Few fates seem worse than living without cause for hope. Yet what is it to have a cause for hope? And how is it related to having hope? Although these questions have received relatively little philosophical attention, I argue that Kant advances a rationalist account of hope that addresses them. My central thesis has two parts. First, hope is a rational attitude for Kant; certain rational conditions are needed to differentiate hope from other desiderative attitudes (such as mere wishing or fantasizing). Second, these rational conditions involve causal inferences made by the hoping agent. To hope, an agent must make certain inferences about the cause of her desire and the cause of her belief that the object of her desire is possible. In short, to hope requires an agent to take herself to have a cause for hope.
