I am trying really hard to find some point to life - being an unemployed atheist widow whose kid has flown the coop does have a tendency to remove most of the obvious ones - so I turned to a little book which I have quoted from before and found this:
But what makes life worth living? Any short answer will sound trite, but there really is no mystery about it. Ray Bradbury put it pithily in his short story And the moon be still as bright. This tells of Martians rather than humans, but the moral of the story translates.From Atheism - a very short introduction by Julian Baggini
"The Martians realized that they had asked the question 'Why live at all?' at the height of some period of war or despair, when there was no answer. But once the civilization calmed, quieted, and wars ceased, the question became senseless in a new way. Life was now good and needed no argument."
When times are hard and life is going badly, life can seem pointless. But when life is good there is no need to question. As in the example above, if one's work and home life are going well, it is in a way senseless to ask why such a life is worth living. The person living it just knows it is.
I don't think this is a complete answer. In fact, I think both Baggini and Bradbury must have been in happy longterm relationships when they wrote these statements - it shows. But there is a kernel of something simple yet profound there. When you are living a good life, it is worth living. When things are going badly, you wonder what's the point of it all. Simple.
Not that this helps much if you are not happy in your work or home life - in fact, it might make people in my situation even more depressed. But the very fact that there are times in your life - when you are busy and occupied and happy - that you do not feel it necessary to ask the question "What's it all about?", is interesting.
