 Objections have been raised against the idea that the standard definition provides sufficient conditions for hope. There are two main lines of objections: the “despair objection” and the “substantial hope objection” (Milona 2020a: 103). According to the “despair objection”, two people can have identical desires and beliefs about the possibility of an outcome, and yet one of them may hope for the outcome while the other despairs of it (Meirav 2009). The “substantial hope objection” holds that even though the standard definition might capture a minimal sense of hope, it fails to explain the special value of more “substantial” kinds of hope. In particular, it fails to explain how hope can have special motivating force in difficult circumstances, especially when the probability of the desired outcome is low (Pettit 2004; Calhoun 2018). These objections either lead to the claim that the standard definition must be revised or motivate the proposal that hope is entirely different from desire and belief, and hence irreducible to them.
