Rosenzweig in prospettiva. Il nuovo pensiero tra vecchia filosofia e filosofia della differenza

Rosenzweig's "new thinking" can be seen, among other things, as the vanishing point of two gazes: one addressed to the "old philosophy" of the past, the other to the postmodernity of the present. The goal of the present essay is therefore twofold: on the one hand, to go back retrospectively to the relationship between critical idealism and the theoretical proposal represented by "Der Stern der Erlösung"; on the other hand, to evaluate, in a perspectival way, what the latter has to say in relation to the philosophy of difference. It is thus possible to investigate the meaning of philosophizing in general and to assess the relevance of Rosenzweig's thought in particular. New thinking is all the more fruitful because it exists in a close dialectic relationship with modern rationality, grasping its "up-to-here-and-no-further" boundary; at the same time, it presents analogies with the postmodern philosophy of difference, without, however, reaching the same antirational conclusions. As for the meaning of philosophizing, Rosenzweig famously thought that the religious experience of revelation could offer a space-time orientation, which is why it was the keystone of his new thinking. However, if one wants to prescind from the "belief" element and find a meaning and orientation in the alogical and purposeless context of postmodernity, one has to yearn for a form that is present in absence: this tension finds its foundation in the up-to-here-and-no-further of critical idealism and is continually reconfigured in relation to difference, both thought-of and experienced.
