Book of Eternal Wisdom (Ketāb al-Hekma al-ḵāleda) is a text composed of different texts. Ketāb al-Hekma al-ḵāleda as an Arabic translation of the Persian work Jāvidān ḵerad comprised various Hikmats from different cultures and so many social horizons. Plural voices of Book of Eternal Wisdom, with the ethics-based Reason in core, in truth, formulated a kind of multiple practical philosophy. Ibn Miskawayh designated an image of a universal and eternal wisdom, and draw a humanistic schema beyond the cultural borders, collecting Iranian, Roman, Indian, pre-Islam Arabic and Islamic Arab heritage. Book of Eternal Wisdom as a polyphonic text is a realm of discovering the Other, promoting political tolerance and learning from the Other. Presence of the Other is an evident matter throughout the book; the Arab other, the Greek other, the Muslim other, and the non-Muslim other. Approval of the Other based upon a humanistic ethics, empties the realistic reason of politics from violence and then drives a concrete border between rationality of practical wisdom of the eternal and the rationality that we find in Realpolitik tradition. Ibn Miskawayh`s practical wisdom has so many potentialities for reconstructing the contemporary political thought on the Old tradition. It is possible to “express” or “re-write” these potentialities upon the contemporary situations.
