Now, I think principles themselves can be debated. Principles always begin with something that is asserted to be self-evident, but as you know even those things which are supposedly self evident can be debated (hence why there are so many philosophies in the world). But for me, my "mish mash" of philosophies seem to agree on many basic principles. Here are some of them (it might take me a while to determine what all of them are)...
Here are my most basic principles, which I feel are self evident, and not in contradiction with christianity or objectivism or other philosophies I have explored:
1) We absolutely cannot KNOW whether there is a God. (Christianity asks us to believe, not to know...Ayn Rand realises we cannot KNOW but then goes further and says it is irrational to believe)
2) Regardless of whether we have free will or not from an external perspective (as viewed by God, in a thought experiment), we perceive that we have free will. Therefore, it does not make sense to assume that we do not have free will and act accordingly. To deny that we perceive that we make choices is to deny being alive.
3) We cannot truly know the final and most basic "what" about the universe. What is an electron? We find that when we bounce other sub atomic particles off of sub atomic particles, we get more sub atomic particles. Or perhaps energy. But...these are all just labels. We will not answer the question: "What." We may describe behavior of all these things from an internal perspective, but we will never answer the external "what," "why," or "how." This is where I find plenty of room for God.
now for the right brained side of my philosophy:
Believing in God, for me, is incredibly inspiring. I feel like I'm serving a great and just King. To speak to him in human language and pray to him inspires me. I know I am not a perfect person, but with the Christian characterization of God that doesn't matter, he loves me anyway.
I feel it is part of human nature to believe in something greater than oneself. Whether that is God, or a mystical sense of wonder about the universe or the ideas of Truth, Beauty and Love, or a political movement, or Beethoven, or whoever or whatever else, all of us believe in something greater than ourselves. Rand believed in Reason with a capital R. Or believed in this capitalist utopia in which producers lived out perfect selfish lives in Atlantis. We all have a religion of some kind.
My belief in God is rooted in the realisation that we don't know anything about the universe. Internally, we can describe some of its behavior with symbols, and predict its behavior in many situations based on that system of symbols. But we will never get outside and really understand it. Only the idea of God makes room for the idea that we might someday understand and view the universe "from the outside," perhaps after death, who knows? I don't know. But I believe in it because it inspires me.
Is that deeper enough for you? haha. Idon't really think of myself as deep. I haven't read all that voraciously in my life, I don't know all that much about history or great philosophers. I just always question everything, constantly...almost neurotically and I never stop. When I realize that I hold an idea that is not well rooted in something I try to go to more and more basic principles until I can't find any more. If there isn't enough there to form an idea, then I assume it probably can't be known and there's no point in going further (this is where belief comes in, if it suits you).
