Optimism is a matter optics, of seeing what you want to see and not seeing what you don't want to see. Hope, on the other hand, is a Christian virtue. It is the unblinking acknowledgment of all that militates against hope, and the unrelenting refusal to despair. We have not the right to despair, and, finally, we have not the reason to despair
