Today's post, Ethical Injunctions was originally published on 20 October 2008. A summary (taken from the LW wiki):

A look at the peculiar properties of decision theories that include rules about not doing certain things, even when they seem like the right thing to do.

Discuss the post here (rather than in the comments to the original post).

This post is part of the Rerunning the Sequences series, where we'll be going through Eliezer Yudkowsky's old posts in order so that people who are interested can (re-)read and discuss them. The previous post was Ethical Inhibitions, and you can use the sequence_reruns tag or rss feed to follow the rest of the series.

Sequence reruns are a community-driven effort. You can participate by re-reading the sequence post, discussing it here, posting the next day's sequence reruns post, or summarizing forthcoming articles on the wiki.
