In my dissertation I am dealing with the value analysis of the prenatal and the postmortal nonexistence. The basic hypothesis of the discussion is that when the person dies she ceases to exist. As far as this is true; and even if it is not; the question is why is death bad for the person who died if death results with nonexistence? After basic determination of terminology and assumptions, in my work I present four models which explain the value of death. The first one is the Epicurus’ model, according to whom the death is value neutral for the person who died. The second model is Nagel's model, the so called deprivation explanation, which explicates Aristotle’s idea of death as the ultimate evil. According to Nagel´s model, the evil of death is unexperienced evil which consist of the deprivation of goods of life. The third model is Feldman's model; more sophisticated model of the deprivation explanation; which as a result has the statement that death is in most cases bad for the person who died but sometimes it can be good or neutral for the person who died. The fourth model is the model which explains the evil of death with a theory of unrealized categorical desires. By analyzing mentioned models, I conclude, that if death is a bad for the person who died, than it is best explained with slight modification of Feldman’s model. However, all mentioned models; except the one of Epicurus; have to answer the question is the prenatal deprivation as bad as the postmortal deprivation, or postmortal deprivation is not bad since it is not prenatal, as Lucretius thought. I believe that deprivation explanation can resolve Lucretius' problem, but in the end it meets the problem of value, that is, it meets the impossibility of proving unexperienced evil to “unshakeable” Epicureans. Since it is impossible to prove to “unshakeable” Epicureans that death is bad for the person who died, my conclusion about the value of death for the person who died, ends with the mild „epicurusaisation“ of the deprivation theory. In other words, I conclude that death is a kind of evil which should not worry us too much.
