The paper sheds light from philosophical and methodological points of view on limitations, imposed on the building of the ontological basis of the theory of quantum gravitation by the quantum field theory: 1. this basis necessarily has to be a constantly fluctuating global dynamic field; 2. the field has to be locally excited and of quantum character, i.e, with local excitations subordinated to the principle of indeterminacy and the principle of canonical relationship between commutativeness and noncommutativeness; 3. sufficient theoretical grounds are needed so that quantum theory of gravitation could justify the basic concepts of the structure of the quantum field theory. The analysis of these limitations should show which fundamental concepts and categories of the quantum field theory could in their transformed forms become a part of the ontological basis of the theory of quantum gravitation.

For the time being the quantum gravity theory is a hypothetical theory having its objective the unification of general theory of relativity (GTR) and the field quantum theory (FQT) into one system with a single language describing and explaining the structures, properties, relations, development and laws of the universe. The ontological basis of the future quantum gravity theory should take into account the limitations imposed on it by GTR and FQT and at the same time be able to explain and predict phenomena explained and predicted by the two theories. The paper discusses the philosophical and methodological aspects which determine the creation of such a conceptual system.

In the introductory part of the paper, we outline the position of the philosophy of physics in the context of naturalistic theoretical philosophy. The main message here is an appeal for understanding philosophy as an integral part of the scientific investigation of the world. In the following sections, we identify three central aspects of contemporary fundamental physics, knowledge of which is essential for philosophical reflection on physics. This is followed by an explanation of one of these aspects, which is the gauge principle. Based on classical electrodynamics, we explain with the help of a relatively modest mathematical apparatus the key idea of gauge symmetry, as it appears in the core theories of the standard model of elementary particles. In the final part, we point out the philosophical relevance of the gauge principle, especially within the current debates between substance- and structure-oriented philosophies of physics.

The question of ultimate constituents of the physical universe was one of the first questions at the dawn of the Western tradition of philosophy. At present, the most successful answers to this question are offered by the fundamental theories of elementary particle physics, which are formulated within the broader conceptual and mathematical apparatus of quantum field theory. The aim of this paper is to explain in an accessible manner the fundamental changes brought about by the transition from particle to field understanding of the universe in contemporary physics. The brief account of Newton’s ontological view of the world serves both as an introduction and as a background to what follows. The paper also intends to address and encourage philosophers interested in ontological problems to study the latest physical theories despite their mathematical complexity and apparent inaccessibility.
