Christopher Hitchens has posted a brief note on Vanity Fair's culture blog, and I reproduce this sad news here:
I have been advised by my physician that I must undergo a course of chemotherapy on my esophagus. This advice seems persuasive to me. I regret having had to cancel so many engagements at such short notice.
Get well soon, Hitch. We will not pray for you, of course, because we know how much that would exasperate you, but you will be in our thoughts.
