I now conclude my series of comments on Martin Hägglund’s stimulating and fascinating This Life. My final point of disagreement with Hägglund has to do with a theoretical possibility: eternal life. Against traditional Christians, neither Hägglund nor I believe that eternal life is possible. But I think Hägglund is right to highlight the question of whether it is desirable.
On his answer, however, I think Hägglund is quite wrong; this is the point where his argument is at its worst. When he rejects the aspiration to eternal life, the rejection appears to rest on surprisingly bad argument. I would agree with rejecting such an aspiration on Stoic or Epicurean grounds – that it is futile to aspire to what we know we can never have. It is wisdom to know that we cannot change the finitude of our life, and so we should seek the serenity to accept that sad fact, as no amount of courage will change it. (There is a hugely significant difference between a 25-year life and a 100-year life, but both remain entirely finite.)
Hägglund, however, rejects the aspiration to eternal life on entirely different grounds:
An eternal life is not only unattainable but also undesirable, since it would eliminate the care and passion that animate my life…. there is nothing to be concerned about in heaven. Concern presupposes that something can go wrong or can be lost; otherwise we would not care…. Far from making my life meaningful, eternity would make it meaningless, since my actions would have no purpose. What I do and what I love can matter to me only because I understand myself as mortal…. (4-5)
I do not think any of this is true.
