The self is a relation which relates itself to its own self, or it is that in the relation that the relation relates itself to its own self; the self is not the relation but that the relation relates itself to its own self. Man is a synthesis of the infinite and the finite, of the temporal and the eternal, of freedom and necessity, in short it is a synthesis. A synthesis is a relation between two factors. So regarded, man is not yet a self. In the relation between two, the relation is the third term as a negative unity, and the two relate themselves to the relation, and in the relation to the relation; such a relation is that between soul and body, when man is regarded as soul. If on the contrary the relation relates itself to its own self, the relation is then the positive third term, and this is the self.
Such a relation which relates itself to its own self (that is to say, a self) must either have constituted itself or have been constituted by another. If this relation which relates itself to its own self is constituted by another, the relation doubtless is the third term, but this relation (the third term) is in turn a relation relating itself to that which constituted the whole relation.
Such a derived, constituted, relation is the human self, a relation which relates itself to its own self, and in relating itself to its own self relates itself to another.
