Can you elaborate on the second part of your question? It’s been a while since I took philosophy classes, and the words that you use are kind of hard for me.

I don’t know if relates to the second part of your comment, but its important to notice that it’s Dialectical MATERIALISM. We relate to the things that can manifest themselves in the material world. The question of whether a tree that falls in a forest makes any noise if there is no one to hear it has no meaning to us Marxist. Life and death manifest themselves in the real life, in the material world.

Ill answer you in a couple of days.
