“I guess some of the most beautiful sights I’ve ever seen in my life have been microscopic views of hideous malignancies.”

“It’s the peculiar magnificence of the human spirit that’s required to provide the potential for such corruption.”

“After all, blood is the life force.  It reaches into the deepest recesses of both the heart and the brain.  It is the familiar of our complete being.  To surrender even one drop of it is to suggest a partial surrender of one’s utmost self.”
