These books have been mentioned on the list before, but I'm recommending them again because a lot of new members have joined since we last talked about them. To motivate you to read these books, I've given some questions that each book helps answer or provide the necessary background knowledge to

I have to say that I sympathize with Caesar, but my position is slightly different. I think there is a possibility that that objective morality does exist, but we're simply too stupid to realize what it is. Therefore we should try to improve our intelligence, through intelligence amplication, or

There are statements of fact, statements of logic (also called analytic or a priori), and statements of value. Statements of fact are verified or falsified empirically. Statements of logic include mathematical theorems and are verified or falsified by following the rules of logic or

Can you explain briefly why the choice of measure is subjective? I haven't read any of the books you mentioned (will try to get to them) but am familiar with computability theory and decision theory. In my favourite interpretation of the multiverse, as a very long (possibly lengthening)

Morality, ethics, virtue, etc. imply a struggle for control -- at least within oneself, but often more widely. If morality had a set of obvious axioms, such as to lead to firm reliable answers to all moral questions in practice, it would be know-how, not morality. For everything there is a
