 There are three prominent arguments for an extreme soul-based perspective. One argument, made famous by Leo Tolstoy, is the suggestion that for life to be meaningful something must be worth doing, that something is worth doing only if it will make a permanent difference to the world, and that making a permanent difference requires being immortal (see also Hanfling 1987, 22–24; Morris 1992, 26; Craig 1994). Critics most often appeal to counterexamples, suggesting for instance that it is surely worth your time and effort to help prevent people from suffering, even if you and they are mortal. Indeed, some have gone on the offensive and argued that helping people is worth the sacrifice only if and because they are mortal, for otherwise they could invariably be compensated in an afterlife (e.g., Wielenberg 2005, 91–94). Another recent and interesting criticism is that the major motivations for the claim that nothing matters now if one day it will end are incoherent (Greene 2021).
