In this paper, the author considers five basic understandings of metaphysics as a philosophical discipline that 1) studies the most general characteristics of everything that is, 2) investigates beings as beings, 3) considers what goes beyond the framework of experience, 4) analyses the most general terms and 5) provides an explanatory theory. In addition, the author considers a number of relevant ideas and distinctions, the distinction between reality and appearance, the distinction between the apparent and scientific picture of the world (Wilfrid Sellars), the idea that philosophy is the queen of science (Moritz Schlick), the distinction between descriptive and revisionist metaphysics (Peter Frederick Strawson), the synoptic view, the idea of naturalised metaphysics, etc. The author accepts the first point of view, the one according to which metaphysics is understood as a philosophical discipline that studies the most general characteristics of everything that is, and accordingly believes that categorical ontology best fits into that picture. After that, the author briefly presents the most famous criticisms of metaphysics (David Hume, Immanuel Kant, and logical positivists), as well as the positions that led to the formation of modern metametaphysics (Rudolf Carnap and Willard Van Orman Quine). Finally, the author considers verbalism and trivialism and tries to determine whether these two positions can represent a basis for the elimination of metaphysics. The author tries to show that these positions do not eliminate metaphysics, but rather set the framework for contemporary metaphysical discussions.
