To me this question is embodied by the saying “it is better to have loved and lost, than to have never loved at all”.
Personally I think that’s debatable. Love and loss are flip sides of the same coin. You can’t have one without the other, except perhaps in the rare special case where you precede a lifelong partner in death, and then you have the knowledge that you’re inflicting that loss on THEM.
This may partly explain the popularity of pets. They let us experience a simplified form of love at a lower amplitude along with the inevitable loss. It’s a form of practice for the bigger attachments and tearings-away.
What I have found is that even when you properly integrate various losses into your “new normal” such that it doesn’t totally define you, each unit of suffering still diminishes you a little, and the effect is cumulative.
This then leads us to the question of “whether to suffer the slings and arrows of outrageous fortune”. I don’t think there’s a universal answer to that one. I have managed to land in a place where I am enjoying the present moment (even hugely at times) and am able to largely protect my peace as I enter the final glide path, but I’m not sure it has been worth the grief / sorrow / pain / dissapointment along the way. I never know whether to laugh or cry when I think about the totality of it. I just blow it off as a sunk cost and concentrate on the present.
Apparently this is what most people do in some form or other or most wouldn’t survive into old age. There is also the instinctive fear of death / will to live and the phenomenon of “hope springs eternal” to “triumph over experience”.
And of course there’s the concept of “no pain, no gain” which is a little different but suggests one must be ever out of their comfort zone to experience growth / progress. This involves risk, which involves pain sometimes.
An optimist would likely say, “embrace all of life, the good, bad & ugly, and forward into the breach”. A pessimist would say, “fuck this shit”. The two have always battled it out inside me.
I have noticed one aspect of psychological trauma that I’ve observed in both my wife and myself, which is that sometimes the brain just disconnects from pain as a coping mechanism. I can’t access detailed memories of the living hell that was my first marriage anymore, and am content to leave it that way. My wife found herself overall emotionally numb for years after a massive betrayal by her father. So sometimes the decision about whether it’s better to feel pain or not, is made for you and you almost have to claw your way back to being capable of the full range of feeling states, or even to possess your own memories. Assuming you choose to. But here’s the kicker: it seem you can’t choose to be impervious to negative feelings without also to a significant degree, damping your positive feelings. The volume control on feelings isn’t selective. So ultimately if you want to be / feel fully human you have to let the feelings – all of them – back in. And from this perspective, it IS better to feel pain rather than be numb. To accept all of what life brings is to fully be yourself – despite any pain.
