  In the second part of the Star, Rosenzweig suggests that we can grasp through speech the relations into which God, world, and the self enter, first and foremost, because speech in fact accompanies the whole of the course that leads from creation to redemption. As that which makes us human, Rosenzweig claims, the power of speech is implicit in every human being since creation; and yet the complete fulfillment of speech in a universal language that would be equally each person’s own and at once common to all, can only be imagined as part of the redemptive future of humankind. In between creation and redemption, language both unites and divides people from one another: we all share speech, but speech is different in every mouth. Within the course of the systematic relations between God, world, and self that stretches from creation to redemption, Rosenzweig thus understands language as a tool of unification that does not reduce different individuals to that which is the same: speech only unites those who recognize or understand each other.
