During the intense philosophical and theological renaissance of the Russian Silver Age, the German Cardinal Nicholas of Cusa (1401–1464) received a unique appraisal in the work of Semyon Liudwigovich Frank (1877–1950), hailed by some as ‘the greatest Russian philosopher’. This paper will show that five of Frank's central philosophical arguments can be traced directly to Cusa's writings. Once these key arguments are taken together with Frank's own comments about Cusa, it can be concluded that Frank saw himself as Cusa's modern successor, presenting his ideas in a different intellectual context. In this sense, we can speak of Frank as the ‘Russian Cusanus’. The arguments in question include Cusa's docta ignorantia, our knowledge of being, the recognition of absolute being as ‘non‐other’, the identity of possibility and actuality in the absolute, and finally the coincidentia oppositorum.
