Materialism and Atheism

Penrose is a physicist that has worked on the great mysteries like cosmology and consciousness. For Penrose, he reluctantly calls himself a materialist because he admits he doesn't know what matter really is even tho he ostensibly is a materialist in practice.

What do you make of this?

In light of the recent "religion" decree on lemmy, how does Penrose's reluctance interact with notions of religon? If there is a non-physical world that interacts with the physical world, then is the non-physical world somehow immaterial? Or could it be material? Can the material be subdivided into "alternative materials" with seperate functions, similar to how structural forces give rise to attitudes, and attitudes give direction to maintain or change structures? Sometimes ideas become so entrenched that they become structural and affect matter beyond what happens in the brain. Similarly, material forces that are not present still affect us (and then those affects re affect us as we contextualize things), for example the actions of our ancestors or the past itself. Furthermore, with any amount of predictive ability, the looming, foreseen future affects the present even though it has not materialized.

Oftentimes we may be off put by a seperation between material and spiritual or non physical, but what if they are still basically the same thing and the distinction is a red herring.

Have a meme for a good start.

Anyway, i would like some opinions on few basic things for this community: what to write in a sidebar, some rules, maybe some reading list, also if someone have idea on a banner and everything else needed to be said and done, since i'm not a philosopher and i never made any instance or mod job anywhere.
