Hope
Hope as an approach or an attitude that humans need to proceed. Questionable, of course...

One can also contrast the understanding of hope as a personal delusion that leads to inaction to the hope as a worldly and action-based mode of behaviour.
Hope is about possibilities and probabilities. These possibilities are communal and shared. The action of hope is about enabling, cf. "provisioning".
"responsible hope is a kind of care for the future, then that care must simultaneously be a process of interrogating the many other futures that are rendered impossible or unlivable through our particular practices of hoping."
What is the target of hope? Who hopes? Who is allowed or acknowledged to hope? How the hoping of some is enabled by the losses of others?

Definitions
Hope is a future-oriented attitude of engagement with the uncertain world.
Not just an emotion.
It is a "mode of worlding", a way to form the world by acting in it in accordance with one's capacity, with various others, in pursuit of some futures in preference to others.
Hope is an effort to care for a possibility in committed, practical, and situated ways.
