Hope is a state of mind, not of the world. Hope, in this deep and powerful sense, is not the same as joy that things are going well, or willingness to invest in enterprises that are obviously heading for success, but rather an ability to work for something because it is good.

This quote is saying that hope isn’t always based on empirical evidence or the idea that something will turn out a certain way. It is more of a feeling that drives us to work towards something we believe is right. It is an optimistic attitude, but not necessarily grounded in reasons why we expect something positive to come out of the work we are doing. Hope is something we can have in our minds, but it is not necessarily the overall sentiment of the world.
