There are more values available for response in human life than anyone can possibly be responsible to.
I think of this as the Not World Enough and Time Problem: we are all missing out on things that are objectively such as not to be missed. That is the human predicament.
I am strongly tempted to think that a lure to relativism, and to psychologizing the values of others, is our desire to deny the Problem: we are never missing out; we just made different decisions, believed or desired different things, than so-and-so did. We aren’t missing out and neither is he, neither is she. But we know–and we do know–that in many cases we are missing out and that we will have to miss out. It may not be our fault, but it is always our loss.
