That is the title of a very good book by Wendell Berry, which in turn takes its title from a 3-page essay which he wrote in 1985. Worthy of several posts, but I'm not ready to tackle that yet.
(Get the book, of course, and read it and lend it out. You'll be glad you did, I promise.)
I think that it is fair to say that in some ways he leaves the question unanswered -- though he has some specific observations and suggestions. But it is the right question, and it is a question that I haven't heard any of us addressing, really. Not beyond a certain level. Not capitalists, not socialists, not Christians, not atheists.
Would you please take about seven minutes of your time and read this recent essay by Fred Reed? Yes, it is very raw, I think.
And get back with me in the comments section, if you will.
What are people for?
