  While this interpretation has the virtue of cohering with Spinoza’s claim that he “always preserve[s] the natural right in its entirety” (Epistle 50), since one’s right, or potentia, always remains intact, it leaves unexplained how potestas, which Barbone and Rice describe as a “super-added” capacity, fits into the natural order. What can it mean to possess, transfer, or renounce one’s potestas? And how can transferring or revoking it result in an obligation, given Spinoza’s utility-based account of obligation?
