A few years ago I got into a ‘discussion’ with a Catholic priest who had said on his blog that there is no purpose in life without God (meaning of course his own particular brand of that particular fantasy.) I argued the opposite: that while some people found purpose wasting their lives worshipping and serving an imaginary being, others found purpose in a wide range of far more worthwhile concerns and activities.
Purpose need not be cosmic in scale nor equate with big, ambitious projects, like saving the world or other people’s souls. A purpose can be modest and parochial; it has only to be meaningful to you. I pointed out to my deluded correspondent that he, like everyone else, frequently had purposes other than a delusional pursuit of God: short term purposes like visiting the store, supporting a sports team, cultivating a garden, writing a blog…
Several scientific studies in recent years have come to the conclusion that having a purpose in life increases one’s chances of living longer. There is a clear correlation between the two. This doesn’t mean adopting a random, makeshift purpose is going to increase your chances of living longer; the purpose needs to be worked out for its own sake, and to be genuine and heartfelt. The potential to live longer is a bonus (good genes and a healthy lifestyle play their part too, of course.)
As for me, as you weren’t asking, my purpose is to enjoy life and to help others, as far as I’m able, to enjoy theirs; to enjoy my relationship with Dennis (having taken so long to be my true self!); to care for my children and grandchildren; to be with friends; and simply to be, here and now. Whether these will help me live to a ripe old age or not, I really don’t care. They give my life meaning and make it feel worthwhile, and that’s all that matters. No God necessary.
