Philosophers and social scientists have focussed a great deal of attention on our human capacity to trust, but relatively little on the capacity to hope. This is a significant oversight, as hope and trust are importantly interconnected. This paper argues that, even though trust can and does feed our hopes, it is our empowering capacity to hope that significantly underwrites—and makes rational—our capacity to trust.

How do we encourage patients to be hopeful without exploiting their hope? A medical researcher or a pharmaceutical company can take unfair advantage of someone's hope by much subtler means than simply giving misinformation. Hope shapes deliberation, and therefore can make deliberation better or worse, by the deliberator's own standards of deliberation.
