But then I came to a realization:  The whole of physics and science in general is observable data.  Data which is observed by the mind.   The mind is like a filter; all the data we are able to observe about the universe is contingent upon the capacity of our brains.  With this realization, the theories and the formulas seemed like a waste of effort to me.  What good is observational data when you dont even understand the mechanism via which you are observing the data?  Without a perfect understanding of the Brain, studying the observable universe is getting a step ahead of yourself.  Its jumping to conclusions.  You have no solid ground to stand upon.

...

And who is the observer?  Though I study nueroscience, I still believe in the existence of an external force upon the mind.  Nature and Nurture are only part of the equation.  The mind is more than just a product of chemistry and life experience.  There is a third force, and is superior to the other two.

That's really interesting.  I went through a similar time when I was trying to figure out what I needed to do with my life.  I used to ask myself, 'What's the most important question we can ask?'.  For a long time I didn't know the answer.  Then one night as I was about to doze off, a loud hypnogogic voice asked 'Who am I?'...and that was it.

I realized that unless I knew who or what is observing the universe, I can't really know anything about the universe at all. 

However, my conclusion was a bit different than yours.  What I felt I needed to know was the observer itself...not the mind which filters what is observed.

You said, 'Data which is observed by the mind'.  I would say that the 'mind' does not observe anything but is (as you also said) a 'filter'.  Therefore, the mind (or brain) itself cannot be fully understood until the observer is understood.

Anyway, kudos on your path!
