More can always be said on the matter, so if anyone would like to present their own views on Aslan, don't let this post stop you! Especially since both threads I'm linking are pretty old, and there may be more opinions about him and his work.

For the meantime, these two threads both take on Aslan and his work:

• A short summary by u/kieslowskifan;
• and the thread in the FAQ about Aslan, with contributions from u/koine_lingua and u/yodatsracist.
