Immortality [Internet Encyclopedia of Philosophy]
Immortality is the indefinite continuation of a person’s existence, even after death. In common parlance, immortality is virtually indistinguishable from afterlife, but philosophically speaking, they are not identical. Afterlife is the continuation of existence after death, regardless of whether or not that continuation is indefinite. Immortality implies a never-ending existence, regardless of whether or not the body dies (as a matter of fact, some hypothetical medical technologies offer the prospect of a bodily immortality, but not an afterlife).
