Whether we have hope within us or we don't: it is a dimension of the soul.... Hope in this deep and powerful sense is...an ability to work for something because it is good, not just because it stands a chance to succeed.... It is also this hope, above all, which gives us the strength to live and continually to try things, even in conditions that seem as hopeless as ours do here and now.
