Abstract
Beginning with the relation between the question of Nature and the status of philosophy, this essay interprets the theme of the mirror through the chiasm between multiplicity and thought. This relation is not substantial dualism’s relation of the subject with the object, but rather, following the image used by Merleau-Ponty, it is like the relation between two mirrors facing each other, thus suggesting that the “subject” herself is a multiplicity. From thence, drawing inspiration from this quote in Eye and Mind, “the Cartesian does not see himself in the mirror”, I formulate both the problem of the body and the question of intersubjectivity as a field of individuation for all possible forms of subjectivity. Following this theme, the essay retraces the use of the mirror in the Note on Machiavelli. Finally, given that the theme of subjectivity as a multiplicity is related to the theme of corporeality, the essay ends with an analysis of the idea of the body-mirror which, from an intersubjective point of view, becomes an expressive relation in which each body is mirror and expression of the whole universe, thus unlocking an existential monadology.
