Every moral theory developed in the Western tradition purports to tell us what a good life is.
Statements
conditional (every = suff. indicator, put on LEFT)
Moral theory developed → Purports to tell us in Western tradition what a good life is
pivot (but, yet, however, nevertheless)
Most people would judge someone perfectly embodying what these theories explain to be a good life as not living a good life (not want they would want for themselves or their kids).
Evaluate
This paragraph gives us two claims, joined by a Pivot word, so normally that means the correct answer will Reconcile the Pivot; it will find some safely worded way of combining what came before pivot with what came after.
The overlapping idea in both claims is "good life". Every moral theory from the West tries to tell us what a good life is. But most people would disagree (for themselves / for their kids) that any of these definitions qualify as "good life".
So we could synthesize into something like, Most people do not agree with Western moral theories, when it comes to what makes a good life.
Goal
Let's look for something safely worded, probably that reinforces the disconnect between what Western moral theories consider a good life and what most people consider a good life.
