Discussions regarding unity in the Platonic tripartite soul generally surround the issue of achieving virtue. However, there must exist some type of fundamental, unearned unity between the parts of the soul prior to achieving virtue which affords the agent meaningful interactions between the three soul-parts and the unity of consciousness. In this paper, I argue that the possession of the rational soul warrants unification of the pre-virtuous soul since the function of reason is precisely to be responsible for the organization and intelligibility of parts. In view of this, I suggest that the rational soul itself is the basis for the unearned unity of the soul. My view is developed against the standing view by Eric Brown in which unearned unification is achieved by the causal relationship between the three soul-parts, which makes the soul-parts tend toward agreement.
