Yet there would be no need to put "me" and/or "you" into the picture if it was all seemless and part of the environment would there? Why do we have a sense of identity and the need to differentiate between anything then?
Or, let me ask you this. Are you capable of discerning between the cup you are drinking out of and the water you are drinking out of the cup? Obviously the two are related (i.e., the process of drinking) but, they're not one and the same.
I feel like I am jumping in with poor timing but, regardless...
Iacchus, there is much experimental evidence through the investigations into quantum mechanics to suggest an underlying oneness, at least at a fundamental level. The problem with this knowledge is that people like RAMTHA/jz knight take this information and twist it to mean something spirtual, or to explain philosphies of dharma..etc...
The best that can be said, is that there is an underlying randomness of probabilities, and some claim that it is the act of cognition or decision making that chooses the reality you experience out of the many potential alternate realities.
An explanatory analogy might go something like this:
There is a computer. The screen represents the continuous reality. The hardrive, is the quantum mess. It contains all the probablities scattered across it's surface in the form of electrically manipulated magnetized particles. The hard disk spins, and the computer searches the surface of the disk for the information it needs to create the continuous reality visible on the screen, the ram compiles it and the cpu processes it ultimately revealing the reality as seen.
The brain is the cpu and ram, and existence in it's entirety is the hardrive.
There is no way to prove the many worlds interpretation so your guess is as good as mine.
Perhaps you should read David Deutsch's book The Fabric of Reality. He is a well respected Quantum Computational theorist, and author, despite being an adamant proponent of many worlds.
Some of the more metaphysical quantum theorists claim that it is the electrical bonds between all particles that is the force behind existence, or god in other words, and that the self is irrellevant. To them there is no I, just matter, and the electrical bonds that hold it together.
In this model, the brain is essentially just a tool for concentrating electricity into thoughts, and this is supported by our knowledge of brain biochemistry, and how it is all regulated by EM radiation that translates possibly through magnetite to the rest of the body, ultimately triggering the bioelectric reactions that dictate the firing of neurotransmitters to create the sensations and feelings we have.
