 Nicholas of Cusa thus combines the metaphors of assimilatio and mensuratio in his account of what provides the cognitive norms or criteria for human knowing. We cannot resolve the tension between the two that we find in what he says, but must hold onto it. The reason is that, as God’s images, we do not create but must recognize what God has created as independent of human knowledge. We may fashion the interpretative measures whereby we know created things, but we do this while acknowledging that the full intelligibility of each determinate reality is ultimately identical with God’s unknowable Oneness. We may aspire to full intelligibility but can reach it only in mathematics. That is why our best knowledge, even of the mind itself, remains conjectural, sharing God’s truth but limited to human ways of knowing.
