So my question is: What philosophical works and authors have you found especially valuable, for whatever reason?
You might find it more helpful to come at the matter from a topic-centric direction, instead of an author-centric direction. Are there topics that interest you, but which seem to be discussed mostly by philosophers? If so, which community of philosophers looks like it is exploring (or has explored) the most productive avenues for understanding that topic?
This thread is for the discussion of Less Wrong topics that have not appeared in recent posts. If a discussion gets unwieldy, celebrate by turning it into a top-level post.
