Immortality: A Beginner’s Guide (Again!), Part 3
A viral rationalist essay argues aging is a solvable disease, not a cosmic law, citing immortal jellyfish.
A provocative essay titled 'Immortality: A Beginner’s Guide (Again!), Part 3' by user MarkelKori has gone viral on the rationalist community forum LessWrong. The post is the third in a series tackling philosophical and practical objections to radical life extension. This installment directly confronts two major critiques: the sustainability of human relationships over centuries and the argument that death is 'natural' and therefore good.
The author dismantles the 'appeal to nature' fallacy, a common cognitive bias where something natural is deemed inherently good. They argue that diseases like AIDS, cancer, and smallpox are perfectly natural yet universally fought against. The essay equates aging to these diseases, stating the only difference is we lack effective treatments for it. Crucially, it points to the existence of biologically immortal species in nature, like the 'immortal jellyfish,' as proof that non-aging life is not a violation of cosmic law but an evolved biological possibility. The conclusion is that death from aging is an evolutionary artifact, not an insurmountable rule, making it a legitimate target for scientific intervention.
- Challenges the 'appeal to nature' fallacy, arguing that fighting aging is morally equivalent to treating diseases like AIDS or cancer.
- Cites the existence of biologically immortal species (e.g., the immortal jellyfish) as evidence that non-aging life is possible within natural law.
- Posits that death from aging is an evolved trait, not a fundamental law of the universe, and is therefore a solvable problem.
