It’s not that I don’t think you’re sincere. It’s that I think you misunderstand. And, you ignore most of my comments on your insults, which leads me to believe that you intended to be insulting. And, I acknowledged the arbitrariness of meaning several posts back and apparently you didn’t read it. So, now I feel frustrated, ignored, and insulted. Still, I will try to add to the discussion. Maybe someone else will read it.
Adding to discussion now.
Humanity’s existence is entirely arbitrary. But, now that we are here, we can decide to give life meaning. We can base that decision on experience – the experiences of continuing and improving the quality of our lives (or failing in these endeavors). If you choose to call that decision arbitrary based on the arbitrariness of existence, I think I can accept that definition. But, for me, life has meaning, I don’t care if it’s an arbitrary meaning. It’s a meaning I chose. It’s a meaning that I care about.
Now, if you add determinism into the picture then my choice was predetermined and my accepting is predetermined and so forth. This depends, I think, on whether there can be randomness and on whether a randomly created consciousness could then make non random, non predetermined choices. This is where I think there is a lot of room for discussion and disagreement even amongst materialists.
