Objective morality in one (admiitedly rather long) sentence: For any moral dilemma, there is some particular decision you would make after a thousand years of collecting information, thinking, upgrading your intelligence, and reaching reflective equilibrium with all other possible moral dilemmas; this decision is the same for all humans, and is what we refer to when we say that an action is 'correct'.
I assume the same but instead of "all humans" the weaker "the people participating in this conversation".
This is a thread where people can ask questions that they would ordinarily feel embarrassed for not knowing the answer to. The previous thread is at close to 500 comments.
