Here is a diverse selection of five ethics-related posts from cyberspace for your weekend reading pleasure:

• Christopher Hitchens analyzes, critiques and updates the Ten Commandments—and does an excellent job of all three, here.

• Over at the American Medical Association’s ethics shop, there is a discussion of the ethical issues in setting and reporting hours for residents.

• The ethical framework used by Jesus in the Sermon on the Mount is the topic of a thorough analysis in the essay, “Ethical Dualism in the Sermon on the Mount.”

• Spiked has a useful essay on the ethical pitfalls, especially bias, in peer reviewed research, a key element of the climate change debate (though one side insists that there is no debate, and is pretty nasty about it, too.)

• Finally, a former Bush Justice Department official takes aim at the Republican attacks on the so-called “Al Qaeda Seven,” a despicable moniker apparently invented by Mary Cheney. There really is no debate here: the suggestion that attorneys who previously represented accused terrorists cannot be trusted to work in Justice is legally, ethically and logically ignorant. Still, it is good to have a Republican lawyer say so.
