Let's see, do you mean something like "Avoid death" as opposed to "Donate to worthy causes: help old people: say your prayers and use Purel"?

What is the law? Do as thou wilt but do no harm.

Hmmm
I am trying to think of when i ever asked myself that. How should we live? I never gave it much thought i guess, i just live my day treating others how i want to be treated. And that includes all 4 reactions expressed. So i guess i do not get a non cognitive spiritual situation, it doesnt make sense to me.

We need to determine the desired end to come up with a means. To me, the desired end is a peaceful society with little fear. This, I believe, is a cognitive approach. How should we live? We should treat each other decently.

The non-cognitive spiritual reply to, "how should we live?" I have been told to please God. I asked; "how do you please God?" The answer was the ten commandment. I do not think that this is a terribly cognitive answer. It is too easy as an answer but not so easy as a practice. But I suppose the desired end is to save your soul's hynie. We still have people being horrendous to each other.

Not in vain our struggle if that makes anysense

There is a variant that might be closer to what you are asking. How should one live? The original question could be interpreted to mean the social contract because of the plural we. In the singular, it is about each of us and what we seek to understand.

“If atheists were to argue that slavery cannot be soul-destroying because souls don’t exist, then I would say that there’s a meaning here that’s lost on them by being overly literal.”

Amen!

Keep asking ourselves what is good, what is truth, what is wisdom, and what is beauty.

My go to saying for this answer that I have posted here many times ...
You do you, I do me and let's strive to do or cause no harm.

My grand father recently asked me this question after the passing of his wife. In his case (he's 90) I asked him what he likes to do most. His answer was that he liked to fish. My response was obvious, go fishing. When my step daughter passed 7 years ago the answer was less obvious. I decided to try to live a my life for a higher purpose (helping others) while my ex-chose to do what she loved most, which was travel. Somehow, I think both answers were correct. For most people, I think the answer is probably that a balanced approach would be ideal.
