By trade I am a "Field Engineer." My job entails interpreting and coordinating all of the various drawings which are used to construct Office buildings, Power Plants, high rise Apartments etc. These would include Architectural, Structural, Mechanical, Electrical, Plumbing, various shop drawings for Elevators, Window and Curtain Wall systems etc...
Part of my job is to find the flaws in the design and make sure that everything will fit where it is intended to fit and look like it is supposed to look. I have to determine what dimensions are true, and which are not true and provide horizontal and vertical controls to make sure the building will be built as true to the design intent as possible.
Hence, all of my investigations seek first to build a foundation.
I was raised Catholic. I believe there is a "Supreme Being" or "Intelligence" underpinning Reality. BUT, from my perspective, since not all People believe as I do, then I must seek to define my beliefs from a physical perspective, founded upon what we can know, or do currently know of the nature of Reality.
So, from a human perspective, what is known, what can be known about Reality and how can humans know these things? I'm deliberately leaving out "intuition" 'revelation" "faith," for now, as ways of knowing as I think that ultimately the nature of reality will reveal the means by which these things are also physically explainable.
So, if the Universe shows a tendency toward greater complexity, culminating in intelligent life and even life that is capable of reflecting upon its self then by definition this is a Universal Physical Principle if the definitions below are true.
I make a distinction between Universal PHYSICAL Principle and Universal Principle.
In all construction, one must first dig down to bedrock or construct a foundation from other material suitable to support the structure to be built. In this context, the Universal PHYSICAL Principle is an idea of how we might support a Structure. Universal Principle is Bedrock. I'm digging for that, but in lieu of finding that bedrock, since it may be too deep to get to initially, with this first construction, I must determine what MIGHT support the structure on material which is less stable than bedrock.
Building a foundation upon material other than bedrock is the more common method, but it does not mean that there is not bedrock below the foundation somewhere. In fact, on my current project, we only ever found clay, and on that clay we poured a 4' thick concrete mat slab to support the 15 story structure to be built.
