In the syndicated aldaily stream, I thought this entry was interesting. To be specific, I thought the blurb describing the article Moral economy of guilt† was more than helpful in understanding the thoughtful and compassionate process of humanity. Although wordy, and at times cause for snoozing at work, Wilfred M. McClay describes the guilt trip perfectly, with supporting references no less.
