Dear Sydney,
As well as you, I stand for extremely clear concepts and a unified picture of the world for physicists, mathematicians, engineers (I myself am an electrical engineer), poets, composers, for the picture of the world of the "LifeWorld" (Husserl). This is the seventh time I am participating in the FQXi's contests and bring this idea in discussions with the contestants. Today, taking into account the deepening crisis of understanding and mutual understanding, the common task of physicists, mathematicians, professional philosophers and amateur philosophers (like me) to understand the structure of the Universum at the deepest ontological level. Like many, I can not agree with the picture of the world, at the beginning of which there is a "big bang".
In my essay, I mentioned an article by theoretical physicist Carlo Rovelli Physics Needs Philosophy/Philosophy Needs Physics. Carlo Rovelli outlined a list of topics currently discussed in theoretical physics. First two of them: What is space? What is time? These are ontological questions ...
What does it mean to "understand"? To understand is to "grasp the structure" (G.Gutner "Ontology of mathematical discourse"). So in my essay I give my understanding of the structure of space as an ideal entity - an ontological structure. This means the ultimate structure, common to Nature and knowledge. The physics of modern times has semantically impoverished the concept of "space".
R. Guardini in his research "The End of New Time" shown the perception of the world by antique and medieval person as follows: "... both have no common for us view of the infinite space-time continuum. For both the world is a limited entity, having outlines and form - figuratively speaking world is a sphere."
The mechanist paradigm of New Time, "paradigm of piece", is a revolution in basic idealities of the worldview: the gnoseological space - "cube" ("Cartesian box") - forces out gnoseological space - "sphere".
Nowadays different ideas of gnoseological spaces without ontological justification (basification) are represented in physics: "curve", "slanting", "fluctuating", "extending" and "toroidal" spaces. The mathematics is responsible for this "gnoseological bacchanalia" in fundamental knowledge. ["Space, time, and number in the everyday life, physics and mathematics" by Zlokazov V.B., Doctor of Physics and Mathematics, Leading Researcher, Laboratory of Neutron Physics, Joint Institute for Nuclear Research]. The centenary problem of an ontological basification of mathematics and knowledge in general, has become extremely sharp. It is connected mainly with understanding of ontological structure of basic ideality - space. The methodology of "grasping" primordial structure of space was traced by E. Husserl in "Origin of Geometry": "... at idealization to consider the general maintenance of the existential sphere, invariant in all imaginable variations."
In your essay and articles, I will also elicit ideas on the main ontological issues for modern science, primarily physics, cosmology, mathematics as the "language of Nature."
Here is your article "On curved spacetime", you note as one of the fundamental ontological problems (questions) for science - the nature of space and time:
聽"So it is not surprisingly that the question about the" true nature "of spacetime becomes very intrigue."
And later: "So how is it possible that the theory of General Relativity and Quantum field theory cannot be put together? Does spacetime exist in the concept of quantum field theory?禄
All these are ontological questions (problems).
My ontological conclusion: "curved spacetime" is a phenomenology. Therefore, it is necessary to "dig" deeper - into the ontology of the absolute forms of the existence of matter (absolute states). The fundamental (ontological) structure of matter, its absolute (unconditional) states, is rigidly connected with an ideal entity - space and its structure is based.
The two main theories of fundamental physics, Quantum mechanics and General Relativity are parametric (phenomenological, operationalistic) theories without an ontological basification. Combining them is pointless - let each work on their own "field" (gnoseological level). How the Ptolemy theory worked for a long time. Therefore, it is so important for physicists to remember the philosophical testaments of A. Einstein:
聽"Often turn over the truths that are settled in physics and mathematics."
"Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world."
聽"At the present time, a physicists has to deal with philosophic problems to a much greater degree than physicists of the previous generations. Physicists forced to that the difficulties of their own science."
聽In order to move from Phenomenological physics to Ontological physics with a more reliable philosophical basis, it is impossible to "turn over" the phenomenological "loads" of theoretical physicists without "crazy" ontological ideas. And the first of the ontological problems is the ontological structure of space and the ontological status of time, that is, the nature of space and time as the basic ideal entities of cognition.
Dear Sidney! Since the discussion with you is very important to me, I have not yet put a rating on your essay, your ideas. But I looked, some "partisan" put a low rating ...
I continue to read works on your blog.
With best regards, Vladimir
