Okay, if the manner in which you think about God and religion and objective morality does not bring you some measure of comfort and consolation, it’s not applicable to you.
On the other hand, in order that others might come to understand this relationship as it unfolds for you [for all practical purposes] you will either intertwine it in a description of the life that you do live or you won’t.
I can only base my own speculations here on the many experiences I have had with those for whom God and religion were an important foundation upon which to engender behaviors that then came to revolve around the “real me” in touch with “the right thing to do”.
As, long ago, it once did for me.
Obviously: It will work differently for different people. That’s the whole point behind exploring the existential relationship between “I”, value judgements, context and dasein.
Historically, it was a spectacular failure. But advocates still today can spin you a narrative that explains why that was the case. And why it had nothing to do with the inherent goodness of Communism. And why capitalism will always revolve around the greatest good for the fewest number.
But, as with God and religion, secular political ideologies are tailor made for the objectivist mind. A psychological foundation upon which to embed “I” in the best of all possible worlds.
Again, it’s less what you believe the font is and more that you believe the font exists.
Ever and always your own.
