The more I think about value monism, I get confused about why some people really want to cling to it, even though our own experience seems to tell us every day that we are in fact not value monists. We care about many different values and also care about what values other people hold. When we ask people who are dying most of them will talk of friendship, love, and regrets. Does all of this just count instrumentally toward one "super value" such as welfare or are there some values we hold dear as ends in themselves?
I came up with a short experiment that can maybe act as an intuition pump in this regard. I would be interested in your thoughts!
Thought experiment: What do we care about at the end of time?
We are close to the end of time. Humanity gained sophisticated technologies we can only imagine. Still, only two very old humans remain alive: Alice and Bob. However, there also remain machines that can predict the effects of medicines and states of consciousness and lived experience.
It seems like the last day for both Alice and Bob has come. Alice is terminally ill and in severe pain, Bob is simply old but also feels he is about to die a peaceful death soon. They have used up almost all of the medicine which was still around, only one dose of morphine remains.
The medical machines tell them that if Alice takes the morphine her pain would be soothed but the effect would not be as strong as normally due to her specific physiology which dampens the effect of morphine. Bob on the other hand would have a really great time if he took the morphine. His specific physiology is super receptive to morphine. He would experience unimaginable heights and states of bliss. The medical machines are entirely sure that net happiness would be several times higher if Bob would take the morphine. If Alice would take it, they would simply have one last conversation and both die peacefully.
How should Alice and Bob decide? What values are important in their decision?
I take the strongest argument for value monism to be something like this: if you have more than one value, you need to trade them off at some point. Given this, how do you decide the exchange rate? Either there is no principled exchange rate, in which case you can’t decide any principled way to trade them off and there is no principled reason to invoke any more than one value when making a decision anyway, which defeats the original intuition for why one would want to recognize more values, or there is some commonality between these values that can determine the exchange, in which case, as it turns out, that is the true intrinsic value, not either of the ones being exchanged against one another. This dilemma always applies when trading off more than one value, so the principled solution will always tend to be finding one common value. There are of course various counterarguments, but hopefully this helps understand why people are drawn to it.
Hey Devin,
first of all, thanks for engaging and the offer in the end. If you want to continue the discussion feel free to reach out via PM.
I think there is some confusion about my and also Spencer Greenberg's position. Afaik, we are both moral anti-realists and not suggesting that moral realism is a tenable position. Without presuming to know much about Spencer, I have taken his stance in the post to be that he did not want to "argue" with realists in that post because even though he rejects their position, it requires a different type of argum...
