Morrison: No. You wouldn't expect to derive "ought" from the raw structure of the universe, and end up with anything that looks like "save children from a burning orphanage", because we know where the structure of 'save children!' causally originates and it doesn't look anything like raw low-level physics. As previously stated, my metamorality is not going to add up to anything morally abnormal - this tells you I am not going to embark on some grand quest for the One Great Moral Principle That Can Be Derived From The Very Structure Of Reality. That, too, is looking in the wrong place.
