Paul Seaton called our attention to a bunch of essays sponsored by the Cato Institute on the quest for indefinite longevity. Only Daniel Callahan is tough enough to recommend that we actually pass laws against those who would invent our way of nature’s deadly, species-centric intention for each of us. Ronald Bailey is the extremist in the other direction, looking forward to the time when free individuals (especially Ronald Bailey) live forever in a world unburdened by children. Diana Schaub beautifully explains the negative consequences of pushing back thanatos will have on eros, but her thought experiment doesn’t really imply any public policy recommendations. The truth, I think, that if we have the capacity to achieve indefinite longevity, we will. There won’t be any effective "pro-death" opposition to it, especially as the voters gets older and older. So the big thought experiment is really to think about how to live virtuously--with responsibility and in love in light of what we really know--under the new circumstances. People will be more anxious and disoriented and so in some ways more unhappy than ever, and it’ll be more important to be good if you really want to feel good. The book to read on this, in MY opinion, is MY STUCK WITH VIRTUE. I do applaud the Cato people for at least beginning to reflect on some downsides of the modern project of reconstructing all of being with free individual in mind. And even Ronald Bailey is to be praised for showing us what an extremely modern man looks like and thinks about. Once again, we can’t forget Darwinian Larry, who reminds us that nature will win no matter what we do. Then, of course, there’s St. Augustine and Pascal, who say that even living a thousand years is nothing in light of eternity--and no modern man really promises IMMORTALITY, just INDEFINITE LONGEVITY.
