He found an excerpt on The Oil Drum:

One of the authors, Sharon Astyk, offers a longer excerpt on the Hen and Harvest:

I've begun to read Astyk's excerpt. She's tackling some weighty issues. For example, to what extent do those with means have an obligation to provide for those without means? What if it involves sacrifice?
I may post more in a bit. I'm curious what others think.
Update: Sharon Astyk has a blog: Casaubon’s Book: Sharon Astyk’s Ruminations on an Ambiguous Future. Sharon Astyk likes to write.
