Abstract

The present paper intends to study Avicenna’s and Nietzsche’s approaches to the relationship between philosophy and medicine by examining their understanding of the multiple analogous meanings of “sickness” and “health” with regard to human existence. Avicenna considers philosophy itself as a form of “medicine” insofar as it can cure the soul from the sceptical doubt concerning the possibility of knowing the truth and thus create a perfect harmony between body, soul, and spirit. But in a second step, he claims that earthly life itself is an “illness” that keeps us from the perfect contemplation of God as supreme intelligible object and, therefore, has to be “cured” by death. Nietzsche shares with Avicenna not only the particular interest in dietetics but also the conviction that philosophy has a deeply therapeutic dimension. However, he replaces the vertical movement of metaphysical ascension towards absolute, divine truth with the horizontal journey of philosophical transformation that allows each human being to find their own inalienable concept of “sickness” and “health” and in doing so, become their own healer.
