Abstract.A new set of metaphysical arguments in favour of fundamental reality is proposed in the article. For this purpose the notion of the state of the world is introduced. The standard concept of grounding underlying metaphysical foundationalism is taken into account. The correspondence of the new notion and the initial principles of metaphysical fundamentalism are confirmed. The proof of fundamental reality existence is represented based on formulated principles and empirical data.

The article deals with the problem concerning the principles of the metaphysics explanatory basis, which provide the achievement of the goals in this most general, most abstract, and, at the same time, the most debatable field of knowledge. Different kinds of explanatory basis in metaphysics are analyzed-cosmic mereological monism, structural cosmic monism, cosmic modal monism, natural substance monism, transcendent substance monism, existential monism, abstract monism as well as the similar kinds of metaphysical pluralism including atomism and space-time pluralism. The implausibility of pluralism and its inefficiency for solving the problems of metaphysics is argued, while for metaphysical monism the need for its clarification as a grounding force is stated. The conception of super-monism is proposed. It is based on the logic of fundamental reality which differs from generally accepted formal logic in that it lacks logical laws, primarily the law of contradiction. The fundamental reality is defined as pure being which is identical with a difference, identity, existence, and the existing. By the identification of the various, this reality is defined as one. By identity with distinction, this reality is defined as the ground of all world diversity. Being which is expressed in terms of difference and identity is reflected in the metaphysical formula, which is proposed as the only tool for describing everything that exists at the extremely abstract level.

The article deals with the problem concerning the possibility of qualitative physics paradigm development and its close connection with metaphysics. The idea of qualitative physics is based on the principles of Aristotelian physics and is opposed to quantitative modern physics (classical and non-classical). It is stated that the essential difference between the two physical paradigms lies in the ways of describing physical objects. Qualitative physics presuppose the qualitative description of physical objects independent of their quantitative description. In normal nowadays physics, on the contrary, physical objects are regarded to be fully determined through quantitative (numerical and structural-analytical) relationships with other objects. The statements of modern physics are considered reasonable if they can be self-consistently expressed by the apparatus of mathematics. The article shows that this way of describing and explaining physical reality is incomplete. There is ground to assert that the quantitative relations of physical objects do not encompass everything that exists in the relations of physical objects. It is argued that there are qualitative aspects of physical reality that are not defined quantitatively and may become the content of special qualitative physics. The conclusion is made that such qualitative physics in its principles and language must be close to traditional metaphysics and can appear to be an application of metaphysics to the field of physical reality.

Abstract. The article presents an unconventional although not absolutely unprecedented view on abstract objects defending the position of metaphysical realism. It is argued that abstract objects taken in purely ontological sense are the forms of objects. The forms possess some common characteristics of abstract objects, they can exist not in physical space and time and play a grounding role in their relation to concrete objects. It is stated that commonly discussed abstract objects -properties, kinds, mathematical objects -are forms.

The article deals with the problem concerning the language of metaphysics. Metaphysics is understood as knowledge about the world as a whole. It is argued that such a perspective needs specific language tools for the description of metaphysical reality. The principal characteristic of the terms of the language aimed at describing the world metaphysically is their ultimate abstractness. It is stated that this abstractness not just corresponds but coincides with the ultimate simplicity of metaphysical reality, that is to say, the reality of the world as a whole. The analysis of the ultimate reality or the absolute leads to the conclusion that both such reality and its depiction is ruled by a special logic different from what is conventionally considered to be logical. Elements of this logic are the ultimate abstractions. As it turned out, logical laws do not apply to extremely abstract objects, first of all, the law of contradiction. In the logic of the absolute, mutually exclusive statements point both to the same and not the same reality. The analysis shows that this is not the dialectical logic of contradiction and denial, it is the logic of the consistent unity and coexistence of identity and difference. The use of identities and differences in their ultimate sense allows us to determine the basic concepts of a metaphysical description-being, existence, the existing, difference, identity. Basic concepts serve as a necessary and sufficient basis for a complete metaphysical description of the entire existing, that is, the world as a whole. Going beyond the basic concepts, we, however, move from the logic of ultimate reality to the usual logic of empirical (physical and mental) reality.
