I'm looking for two things I think I found on this website.

One is a philosophy paper that argued that deontology was merely the rationalization of unconscious moral heuristics (or something like that...). Meaning that people have unconscious moral instincts that they arrive at unconsciously, then they try to justify them, therefore deontology. I think I remember getting access to it through LessWrong, though I don't remember, nor do I remember who it's by (maybe Joshua Greene)? Anyway it was really interesting and I'd be grateful if someone pointed me to it!

Also, the second thing. There's a LW comment somewhere that I'm trying to find. It was talking about personal identity, and how the concept needs to be dissolved. It was kinda long-ish, it had about forty karma, and I think it was made by someone whose username started with 'k'. I searched for 'personal identity' in the search box and I wasn't able to find it. If someone can help me find either of these, I'll give them love.
