A book about slaughterhouses raises questions about eating meat:

On the matter of animals and meat I am, as amateur psychologists would put it, conflicted, veering between the ruthless and the sentimental. In my heart, I believe that I ought to be a vegetarian, though I continue to enjoy eating meat. A couple of months ago, for example, I had the best veal chop of my life, furnished by our excellent and amiable butcher. But even while enjoying it, I knew that my enjoyment was bought at the cost of avoidable suffering.
