Is it repugnant?

Derek Parfit‘s ‘Repugnant Conclusion‘ is that for any world of extremely happy and fulfilled people, there is a better world which contains a much larger number of people whose lives are only just worth living. This is a hard to avoid consequence of ethical theories where more of whatever makes life worth living is better. It’s more complicated than that, but population ethicists have had a hard time finding a theory that avoids the repugnant conclusion without implying other crazy seeming things.

Parfit originally pointed out that people whose lives are barely worth living could be living lives of constant very low value, or their lives could have huge highs and lows. He asked us to focus on the first. I’m curious whether normal intuitions differ if we focus on a different form of ‘barely worth living’.

Consider an enormous and very rich civilization. Its members appreciate every detail of their lives very sensitively, and their lives are dramatic. They each regularly experience soaring elation, deep contentment and overpowering sensory pleasure. They are keenly ambitious, and almost always achieve their dreams. Everyone is successful and appreciated, and they are all extremely pleased about that. But these people are also subject to deep depressions, and are easily overcome by fear, rage or jealousy. Sometimes they lie awake at night anguished about their insignificance in the universe and their impending deaths. If they don’t achieve what they hoped they can become overwhelmed by guilt, insecurity, and hurt pride. They soon bounce back, but live is slight fear of those emotions. They also have excruciating migraine headaches when they work too hard. All up, the positives in each person’s action packed life just outweigh the negatives.

Now suppose there is a choice to have a small world of people who only appreciate the pleasures, or a much much larger world like that described above. Perhaps it turns out that the overly pleasured people are unable to be made productive for instance, so we can choose a short future with a large number of people enjoying idle bliss with our saved up resources, or an indefinitely long future with an incredibly much larger number of productive people each enjoying small net positives. How crazy does it seem to prefer the latter at some level of extreme size?

 

I give my interpretation of the results here.
