Well, we're living in a material world, and I'm a material girl... or boy.
Through a long and painful process, I've learned that happiness is an inside job - not based on anything or anyone in the outer material world. I've become a different and better person - not perfect, but still a work in progress.
I would say I was still a Marxist - which is not to be confused with being a Communist. Despite its flaws, Marxism still seems to explain the material world better than anything else.
I can't see any great evidence that humans have any ability to access anything other than the material world. Beyond that, who knows, but there's no good evidence that would take me to any particular belief.
Modern scientific knowledge appeared piecemeal. Historians wrote about human history; physicists tackled the material world; and biologists studied the world of living organisms. But there were few links between these disciplines, as researchers focused on getting the details right.

Subject the material world to the higher ends by understanding it in all its relations to daily life and action.
It does not appear to me to be open to question that there is in the soul of man a nature and an order obtaining in it as permanent and universal as in the material world.
We should seek to love our lives and live fully, but not to extend them indefinitely. We should love our children exuberantly, but not cling to them or curtail their freedoms. We should treasure the material world without seeking to own and control it.
