During the previous chapter I explored the problematic relationship between substance and attributes as presented in the Ethics and looked at Deleuze's response to the contradictory objectivist and subjectivist interpretations of the relationship. I investigated how the notion of formal distinction might be adapted from medieval philosophy but concluded that Deleuze could not give us a satisfactory answer as to how we might know that the attributes refer to, or are attributed to, the same substance. Because these attributes are in fact the properties of thought and extension there is already a suspicion that the realist or materialist waters are being irretrievably muddied. After assessing his arguments for the identification of God with attributes, I concluded that the account of formal distinction, his "weakened sense of real distinction", fits well into his own project but fails to deliver a proper solution to the ontological problem of the existence of God.
