Lucretius’ symmetry argument is always understood as a simple addition to Epicurus’ deprivation argument. Both are based on same presuppositions and both are referring to the state of being dead. However, by closer examination, we can see that they are using different perspectives. The symmetry argument adopts a first-person perspective, whereas the deprivation argument adopts a third-person perspective. According to this difference, it can be further inferred that the symmetry argument actually provides a very important supplemental argument for the deprivation argument by trying to bridge the potential gap in the deprivation argument.
