Another month, another rationality quotes thread. The rules are:
Provide sufficient information (URL, title, date, page number, etc.) to enable a reader to find the place where you read the quote, or its original source if available. Do not quote with only a name.
Post all quotes separately, so that they can be upvoted or downvoted separately. (If they are strongly related, reply to your own comments. If strongly ordered, then go ahead and post them together.)
Do not quote yourself.
Do not quote from Less Wrong itself, HPMoR, Eliezer Yudkowsky, or Robin Hanson. If you'd like to revive an old quote from one of those sources, please do so here.
No more than 5 quotes per person per monthly thread, please.
The doctrine of transubstantiation was off-and-on in Christianity from the third or fourth century but wasn't actually adopted by the Catholic Church until the 4th Lateran Council in 1215 AD. It wasn't formalized until the Council of Trent (1545-63 AD). So, to a 12th Century monk, transubstantiation may have been a "knotty theological question" but of no concern where salvation was concerned. I was kind of impressed how well Follet did his homework for that book.
