Jose,
You make a brave and well founded "..attempt to formalize a concept of 'Fundamentalism'." which I think was well presented and largely successful. I'm glad I got to it and find most agreeable, certainly that; "theoretical model-building based on fundamentals can lead us to the truth." (but) "..the search for truth based on fundamentalism gets derailed due to errors."
As another down to earth realist I also very much liked and support;
"if the fundamental entities have a beginning, they will just pop out in space, remain confined in a finite region of space and will just disappear within a finite time."
"Mathematics has no role in deciding the properties of the fundamental entities. However, mathematics decides the emergent structures"
"for complete predictability, we have to measure or quantify all causal factors"
"space and time factors connected with matter are quantized and finite, and are parts of systems."
I really couldn't find much to argue with, and am interested in your bio comment; "motion (at speed 'c') is a property of matter,"[/c] I found a whole thesis partly on that, but more specifically electron (fermion) spin at c and as the modulator of local local speed c. The de-paradoxing of SR that can bring is extended in mine this year to remove non-causal weirdness from QM. It won't pass the gatekeepers of doctrine but I think you'll like it! Do comment there.
Nicely done. I'm sure you've been 1 bombed as I have so my score will help compensate.
