Metaphysical thinking can be regarded as a rational transcendent language which determines the form of the classical and neoclassical logic languages through which we talk about existence of the objects in thinking of consciousness. The form of the logical subjectivity and its possible interpretations determine the object nature of consciousness. According to the structure of the logical language, the object nature of thinking in consciousness could be made relative or absolute. The relative form of consciousness is determined by the metaphysical language rationality as a necessary apriori logical condition in constructing the objects of the transcendental consciousness, while the absolute form of consciousness has nonlogical condition (it could be mathematical, physical, natural language, existential, ethical, aesthetical, theological, etc.). Metaphysical thinking constitutes the ontology of existence and eliminates non-logical condition of consciousness.
