Hope is a state of mind, not of the world . . . Either we have hope or we don’t; it is a dimension of the soul, and it’s not essentially dependent on some particular observation of the world or estimate of the situation.
Hope is not prognostication. It is an orientation of the spirit, and orientation of the heart; it transcends the world that is immediately experienced, and is anchored somewhere beyond its horizons . . .
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 and ability to work for something because it is good, not just because it stands a chance to succeed. The more propitious the situation in which we demonstrate hope, the deeper the hope is.
Hope is definitely not the same thing as optimism. It is not the conviction that something will turn out well, but the certainty that something makes sense, regardless of how it turns out.
