Can I submit a rebuttal to an essay that The Examined Life has published?
Yes, and this is encouraged. The dialectic is one of the most crucial tools used in philosophy, and the only way that this can be accomplished is by one or more philosophers interacting with their ideas. Rebuttals, however, still must meet the criteria for publication, and they must not be personal attacks (ad hominems). If you would rather address the issues that you have with a published piece at the discussion forum, you are free to do so. You may also do this in addition to submitting a rebuttal for publication.
