This is the term used to describe science which rejects the materialist paradigm. Many scientists now subscribe to various post-materialist theories, and indeed Quantum Physics could be regarded as post-materialist science. (Please note that Wikipedia’s entry on post-materialism is nothing to do with post-materialist science, that subject is omitted intentionally due to the materialist paradigm which governs Wikipedia’s editors.)
This does not mean that post-materialism necessarily involves a belief in ‘God’. I don’t even know what that term means with a capital letter. I know there are many ‘gods’ with a small ‘g’ and this word is used to described anything or person which is worshiped, including a deity. But what is a ‘deity’ or the ‘Deity’ come to that? Does it exist at all?
I used to describe myself as an atheist, but that sounds far too negative for someone like me who accepts the evidence that consciousness is the fundamental reality, and therefore we all survive death. Post-materialism suggests Mind and Brain are separate, and that the brain is a receiver/transmitter rather than the actual seat of consciousness.
Rationalist is a word I prefer to atheist, because I subscribe to no faith or religion. I also call myself an agnostic Spiritualist meaning I don’t know about ‘God’ because I don’t understand what the term means, but I do receive communications from spirits who are no longer on our Earthly dimension.
Fewer people today believe in a father figure in the sky who judges us. Those who have had Near Death Experiences sometimes talk of encountering a ‘Being of Light’ which some interpret as God, that doesn’t really explain the nature of what they actually encountered. A higher Spiritual Being presumably, but is that necessarily ‘God’?
As an agnostic I admit I don’t know whether God exists or not, but if it does it’s had a very bad publicist and I would want nothing to do with the ‘God’ of the Old Testament, for example. If we are referring to the sum total of Consciousness in the multiverse, I would not use the term ‘God’. Nor would I use that term to describe the most highly evolved part of that Consciousness. ‘God’, in the traditional sense of the word, does not evolve but is unchanging. ‘God’ is also described as the Creator, but this is problematic too as it implies a beginning and Time is only the 4th dimension of our physical world, it does not exist in other realms. Everything is eternal, everything is ‘now’ if you like, there is no beginning and no end.
Many refer to Source, and that sits better with me as it suggests a pool of Consciousness which we all emanate from and return to, and which is constantly evolving. Scientist-engineer the late Ronald Pearson suggested an all-pervading Matrix he called the ‘intelligent ether’ or ‘i-ther’.
Whatever term is used, a Consciousness which is constantly evolving, even though it exists outside the physical brains of living things, is not accurately described as ‘God’ in my view, and it encompasses all of us.
A scientist once said that it appears everything is basically a Thought, and Quantum Physics would also suggest this since sub-atomic particles collapse to wave function (‘waves of probability’ or thought?) when not being measured or observed. This strongly suggests that all matter, none of which is really solid, is a product of Mind or Consciousness.
Yes, post-materialism and Quantum Physics seem weird. For those who want a simple model of the Universe it is uncomfortable. Einstein never liked Quantum Physics, and after he turned 70 is said to have doubted his theories would stand the test of time since some of them were incompatible with Quantum Physics. Such as sub-atomic particles which can be in two places at once, and which can react with each other instantaneously when thousands of miles apart, thus far exceeding the speed of Light, for instance.
The 21st Century will prove to be when post-materialism becomes the accepted paradigm. We will need to accept we are living in one virtual reality among many created by Consciousness, and that we are all connected. The idea of a personal ‘God’ creating itself and then the Universe is as outdated and unsatisfactory as an explanation as that a Big Bang created the Universe out of nothing. Consciousness is energy which cannot be destroyed, it can only change form. That is the underlying basis of all post-materialist theories.
