Well when someone can produced a coherent version of dualism (or trism etc.) I'll happily look at that until then I'm sticking with my belief that reality is just made of stuff.
Exactly.
I'm an atheist, yes, however I'm a skeptic first and foremost. Atheism is just one possible conclusion one can arrive at using a skeptical methodology. All atheism means is that I don't believe in any worshiped beings called gods. More specifically in my case, I have my own ideas about what gods, souls, angels, and demons are, which as you might suspect are in complete conflict with the theistic worldview. To put it another way, I reject the theistic definitions of god and the gods.
What does god mean to me? God is creation itself, not the creator. Gods are people. You are god, I am god; we are all gods in the sense that we are each responsible for shaping our world and how we see it. God represents the best and the worst that humanity is capable of. Angels and demons are people as well, representing the sides opposite the line between good and evil drawn down the middle of each of us. Souls are one and the same as our minds, and our minds are simply a subset of the physical workings of our material brains. There is nothing supernatural, because nothing supernatural is necessary.
As a skeptic, I believe only so far as there is evidence to show me. I reject absolute certainty, and I remain open to the possibility that I may be wrong. Being wrong, after all, means learning something new. I wouldn't assert that there isn't something more out there in the universe that is beyond our comprehension. In fact, I would say that there are such things, given that we have only explored an infinitesimal percentage of the universe. If however we were to discover or encounter such an entity one day, I believe the most reasonable thing to do would be to learn as much as we can about it, and possibly from it. Not get on our knees and start sending up worship and prayers.
