If metaphysical naturalism is true then your thoughts and feelings have no real significance or meaning. Its just a chemically induced fantasy in your head, no different from a person having a delusional belief in God.
I’m going out for dinner tonight.
If you like I will do my best not to enjoy the company of some very good friends. I will try not to feel proud of my daughter when she arrives and how she is raising her son. I’ll dismiss the tightness in my throat when my grandson hugs me.
I will overlook the feelings I have for my wife of many decades. I will ignore the fact that I am missing my son and his partner and they’ve only been overseas a few days. I will treat the sheer unadulterated pleasure of my recently arrived brother’s company as a mere frippery.
I will promise not to enjoy that bottle of red I was planning to take with me or the excellent food we’ll be having. I certainly will do my best to ignore the great weather and the beachfront location and the fact that I don’t have to go to work tomorrow but will enjoy a great day at the cricket with my son in law.
If it will confirm your beliefs, I will not be amused by anything anyone says or be interested in any topic they bring up. I will refuse to smile, let alone laugh out loud. After all, none of it has any significance.
And if I should find myself sitting alone on the deck tonight with a glass of good whisky, looking at the stars and listening to the surf in the distance, I won’t contemplate how lucky I have been and how lucky I still am.
But sometimes, and it may sneak up on me tonight, because I am in such a good mood, it will come to me what I have and I will realise that I can’t have it forever. And if Caz comes out looking for me and says maybe it’s time for bed, I’ll have to pretend to have something in my eye.
I don’t fear death at all but gee, you don’t half miss a lot of things when you’re gone.
