When people fear death, they fear an eternity of non-being. And yet, when you think of it, the alternative — immortality — may be just as scary. To live to 100 would be to have a long, rich life, and perhaps living to 200, 300, even a thousand would allow us to explore all the avenues of experience we’ve ever dreamt of exploring. But forever? At some point, I imagine everlasting life might feel as confining as everlasting non-being.
Perhaps what we are truly afraid of is the infinite. There is a freedom that comes from the finitude of life, and a beauty to its brevity and its mystery.
