This article deals with the question of existence by considering the way in which phenomenology has faced this issue. To provide an argument against the ontological certainties typical of idealism and realism, I try to show the possibility of a subjective reduction of the question of existence and to highlight the way in which the concept of existence may be “undermined” by this reduction. A prominent place is given to the concept of infinity for radically reassessing the content and scope of the concept of existence. I try to integrate some of the main themes of Husserlian phenomenology without being restrictively committed to it. I include some discussion of foundational mathematics and of quantum physics.
