It is a truism that life is short. But this truism is in tension with the very plausible claim that life-long commitments are hard. So which should go?
Or can it be, perhaps, that life-long commitments are hard—for those who have not existentially appropriated the shortness of life? If so, then we would have the following prediction: In societies where individuals are socially isolated from the fact of death, well-kept life-long commitments are more rare (either because life-long commitments are more rare, or because they are kept less well). I suppose this is one of those predictions that it would be really hard to make sufficiently precise to check.
