The article aims to substantiate the genesis of consciousness and self-consciousness through metaphysical thinking. Metaphysical thinking is explicated as a transcendence that a priori determines every possible object of consciousness. In this sense, metaphysical thinking determines a priori the unity of existence. Existence is explicated as a unity of the interpretive models of consciousness. Thus, metaphysical thinking is seen as a function of the transcendent unity that is the a priori truth of the consciousness’ genesis. The logical relation between metaphysical (...) thinking and consciousness is expressed by asymmetric implication. In this way, existence in the language of consciousness is phenomenologized. Thus arises the ontological understanding of existence. In this sense, metaphysical thinking determines the transcendental form of consciousness and the ontological form of existence. (shrink)
