An analogy for “sharing common understanding of morality”. In the sound example, even though the arguers talk about different situations in a confusingly ambiguous way, they share a common understanding of what facts hold in reality. If they were additionally ignorant about reality in different ways (even though there would still be the same truth about reality, they just wouldn’t have reliable access to it), that would bring the situation closer to what we have with morality.

Can you elaborate this a bit more? I don’t follow.
