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.
