Interesting review of life-extension technologies in the WSJ. A few small quibbles, though. The author, Sonia Arrison, writes:
Arguments against life extension are often simply an appeal to the status quo. If humans were to live longer, we are told, the world, in some way, would not be right: It would no longer be noble, beautiful or exciting.
But what is noble, beautiful and exciting about deterioration and decline? What is morally suspect about ameliorating human suffering?
The answer is nothing. Everything that we have, socially and as individuals, is based on the richness of life. There can be no more basic obligation than to help ourselves and future generations to enjoy longer, healthier spans on the Earth that we share.
I’m not sure if anyone’s arguing that deterioration or decline are noble, exactly. What can be noble, however, is accepting the inevitably of death and living life in a way that reflects that awareness.
As to the final paragraph, I agree that helping people live longer, healthier lives is a worthy goal. But I’m concerned with access: at least in the near-term, I can imagine that life-extension technologies will disproportionately benefit the wealthy and privileged (even if they do eventually make their way to poorer populations).
And it’s that meantime that’s interesting: alleviating the suffering of the destitute strikes me as more urgent and more ethically compelling than extending the lives of the already healthy and well-to-do. To the extent that we can do both, great. But to the extent that resource constraints require a choice, I’d want to foreground the avoidable suffering that’s all around us.
