Abstract The aim of the paper is to argue that there is a mutual relationship between the concept of being as it is conceived of in the classical Aristotelian metaphysics and the plurality of possible metaphysical discourses. That thesis is rooted in the inherent ambiguity of the concept of being and some consequences connected therewith. Three forms of metaphysical thinking are taken into account: the metaphysics of formal interpretation of the concept of being, metaphysics of existential determination of being, and metaphysics of the material content of every conceptual representation of being.
