This review will consider two recent works on immortality in Greco-Roman philosophy: a 2019 monograph written by Alex G. Long and a 2021 volume edited by him.

In his strong and engaging monograph, Death and Immortality in Ancient Philosophy, Long examines the wide variety of approaches to death and immortality found in ancient Greek and Roman philosophy. Rather than focusing on familiar arguments for and against the possibility of an everlasting postmortem existence, Long offers a revisionary approach that explores the many ways that ancient thinkers thought immortality could be achieved and the different types of consolation philosophers offered in the face of death. Long wisely starts with immortality, arguing that this concept is flexible, with a broader range of uses than many scholars acknowledge. For Homer and other early authors, the epithet 'deathless' is tied to being owned by the gods or acting in ways similar to the gods (28). It can be applied to things that will perish because godlikeness, rather than long or everlasting duration, is what makes something deathless. Long notes the Homeric terms for 'immortal' in a footnote but does not offer detailed discussion of the etymology and meaning of athanatos (literally, "deathless" or "undying") and other key terms in detail anywhere in the work. Given Long's interest in the boundaries of immortality, this is a missed opportunity. Exploring the semantic range of the relevant terms more explicitly would bolster Long's case.

Long rightly points out that in thinking about immortality we need to consider what endures—the human, the soul, some other part, or some connected entity—and how it endures, instead of simply asking whether something is immortal. Long convincingly argues that ancient philosophical schools that do not take humans or souls to be everlasting still have coherent and important notions of immortality. For Epicureans, virtue and other true goods are immortal insofar as they are inalienable from the person, "securely possessed as long as the person is alive" (74). This distinguishes them from wealth or fleeting psychological states. For Chrysippus and other Stoics, all things other than Zeus are subject to destruction at the end of each world cycle. But, Long insists, Stoics can still distinguish mortal things, which are subject to death, from things that cannot die, even though these things will at some point cease to be. Long makes the case for thinking that this allows the Stoics to recognize something as a god, an "immortal living being" (Diogenes Laertius 7.147), even if it will not survive the next cosmic conflagration. On this reading, the sun, moon, and other "intra-cosmic gods," as Long calls them (79), are rightly seen as immortal, even though Zeus alone will persist through the cosmic cycles.

At points, however, Long goes too far in diminishing the importance of duration for immortality. Long maintains that, for Plato, everlastingness is not relevant to immortality because longer duration turns out to make the vicious person's life worse (35–36, discussing Gorgias 481a–b, 512a–b; and Laws 661b–c) and because a short-lived virtuous and knowledgeable person is more immortal than a long-lived and ignorant one (58–59, discussing Timaeus 90b–c). Long notes that Socrates insists that you can only benefit from [End Page 515] immortality if you know how to use it (36, discussing Euthydemus 289a-b). But none of these considerations establish that everlastingness is "evaluatively neutral" (36). In these passages, the length of life is often compared to items such as sight and health. These, too, do not benefit the ignorant or vicious since such people cannot make good use of them. Nevertheless, sight and health are still good for the wise and virtuous, not purely neutral. As Long concedes in interpreting Symposium 207a, Diotima really does claim that we...
