Hi Graham,

the difference between indefinite and infinite lifespan I want to grab mathematically is this, conceptually framing it: if one is treated with what I call Open Healthspan Technology, all of the known internal ageing related caused of death is prevented, but this does not mean that there won’t be unknown ones emerging that might kill people off, and it certainly does not mean any external causes of death (all of your wipe-our scenarios and much more) will be eliminated, so this means indefinite lifespan with a daily non-zero mortality rate.

As opposed to this scenario, infinite lifespan is what I call immortality means a zero mortality rate on a daily basis, so practical invincibility that applies to all known ways to death (internal and external) that now can be avoided. And here we can include all of your wipe-our scenarios too. Continue reading “Correspondence with Graham Oppy on mathematical difference between infinite & indefinitely long lifespans; part 3”

Hi Graham,
thanks, I’m blown away by the breadth of this argument, and the finite list assumption on strong upper bound ‘wipe-out’ events of humanity’s existence make sense. I need to think a bit more on exactly what kind of mathematical argument is this, seems familiar from analysis, some middle value kind of argument maintaining existence but not showing unicity of an opportunity, but am running ahead of myself.
However, my question is really framed with an individual human being in mind, and assumes a technology that eliminates all internal aging-related (very distal and not proxy) causes of death and assumes only non-zero chance of dying every day (every minute, every second,…) from external causes.

Dear Professor Oppy,
Attila Csordas here, aging/longevity biologist and philosopher, based in Cambridge, UK. My philosophical work concentrates on the philosophy of indefinite longevity, the upper limit, still possible scenario of biomedical life extension technologies, with a non-zero mortality rate. ‘Indefinite’ here capture the possibility of technology providing indefinitely long lives but also capture (epistemologically) our current scientific understanding (or better the lack of) of being genuinely uncertain about how far we are able to push human lifespan with technology. Just because we know no bounds here, it does not mean this that there are no bounds. This formulation is new and am working on a book on it, called Open Lifespan However still majority of people are stuck with the term immortality and its connotations when thinking about this, both pro and contra, so am looking for ways and examples to phrase indefinity and indefiniteness helping me clearly to distantiate it from infinity.

50 GBP reward for the best mathematical analogy of indefinitely long, open lifespan!

Hey mathematicians or just all-around math-savvy people, I have an offer for you: I pay 50 GBP for the best suggestion that is using a mathematical concept that captures indefinitely long Open Lifespan in a way that gives me an a-ha moment so I can incorporate it into my philosophical treatment of the topic.

You have until 17th of December, 2018 to come up with suggestions that can be rewarded. Continue reading “50 GBP reward for the best mathematical analogy of indefinitely long, open lifespan!”
