Today's post, The Magnitude of His Own Folly was originally published on 30 September 2008. A summary (taken from the LW wiki):

Eliezer considers his training as a rationalist to have started the day he realized just how awfully he had screwed up.

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 Above-Average AI Scientists, 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.
