I would donate any organ I could, always, of course. With time, I am more hesitant.
The power of organ donation seems to be how the donor is able to give someone decades of life with a fairly minimal sacrifice (some risks in surgery, and then some part of the body that will grow back or was redundancy anyway.) The donated organ becomes so much more, and that more-ness seems to me remarkable.
With time, it all depends. Donating time, I couldn’t simply give someone decades of life without making myself a martyr, without forcing them to live the hours of my martyrdom. That doesn’t seem nearly as uplifting, nor does it seem a very meaningful martyrdom.
Where organ donation is about gaining time—donating time cannot be. No time is gained, only exchanged, so the more-ness, the gain, must be elsewhere: qualitative. If all the time meant was that my loved one got more time and I got less, I wouldn’t give them anything—if the time wouldn’t be more meaningful to them than to me—if the time wouldn’t alleviate pain or solve some other qualitative issue—I don’t think they’d want it.
If my loved ones were dying from something painful, would my time “cure” them, or would it only prolong their suffering? If it could cure them, and they were in horrible pain, I would give them time (I’m not sure how much) so they could have their last moments in peace, able to offer final wisdom and farewells—that seems meaningful. But if it cured them, why would they still have to die? . . . Would they experience my final moments (my death) whatever it was, or would they simply drift away? If I could give them a guaranteed peaceful end, that seems worth it.
If I gave my loved one several years of my life and then they were hit by a car with enough force to kill them, what would happen to the years? Would the years I gave them simply expire? Would the person live out the years and then die? (But they were so injured—if this time doesn’t cure them, would those years be in a coma?)
Bill Gates isn’t my loved one—still, I would be sad to hear he was dying. And the potential millions that individuals could make by selling hours of their lives could mean everything to them. But I think I would be disappointed in Bill Gates if he made such an offer, and I think it would set an unpleasant precedent. Our economy is already based on one form of selling time—employees offer their time in work, employers buy worker time—would we really want to offer this second form? It reminds me too much of the JT movie In Time. I doubt hours would ever actually become currency, and the scarcity of these interactions (millions for hours) could be beneficial at the individual level, but imagining it as a part of society makes me uneasy.
Long story short: I wouldn’t sell my time on principle. I would only give my time to loved ones if I could be sure it would make their final moments better—I can’t stop their death; I’d want my donation to be more than postponement, time displacement. Maybe that makes me selfish?
