According to a prominent view of organism persistence, organisms cease to exist at death. According to a rival view, organisms can continue to exist as dead organisms. Most of the arguments in favor of the latter view rely on linguistic and common sense intuitions. I propose a new argument for somaticism by appealing to two other sources that have thus far not figured in the debate: the concept of naturalness, and biological descriptions of organisms, in particular in ethology and ecology. (...) I show that if we hone in on the relevant notion of naturalness, we can show that organisms can continue to instantiate the natural property being an organism after death. (shrink)
