Are the Kurds a nation without history or the forgotten nation of the history?Are the Kurds Iranian or non- Iranian?Who are the Kurds? What do they want?Why did the beginning of history become the end of the Kurd and why the end of history is the beginning of Kurd?Why were the Kurds labeled as Jin (fiend), Satan and sometimes irrationals in religions and myths?Why do the researchers consider the Kurds as part of the history of Islam and Iran?Why do Iranians, Arabs and Turks, that have always been bloodthirsty hostile to each other, become intimate friends in contrast to the Kurds?What are the secret behind all these hatreds towards the Kurds which we saw its current example in flagrant violence of ISIS towards the Kurds?This book, not only, provides suitable answers for these questions, but also, utilizing reliable and valid resources and data, it proves that the Kurds are not Iranian and the Iranian Political Rationality, with all its components (myths, religions, and ideologies), has been developed and has continued in contrast to the Kurdish Identity. Furthermore, this book shows that the pivotal or axial period with the advent of philosophy and religion has been developed in contrast to the Kurdish Identity. The relationship between Iran and Kurd is the relationship of suppression and confiscation. Along with the historical severe suppression of the Kurds, the Kurdish-Mithraism symbols and concepts have been confiscated and their meanings have been transformed by the metaphysical religions (Jewish, Christianity and Islam) and by philosophers (Plato and sophists). If, based on Hegel and Nietzsche, history and metaphysics were developed with Iran and Zoroaster, we will find out in the current book that the Kurds were "the other" of the history and metaphysics since Zoroastrian and Iran were not developed except through the suppression and confiscation of the Mithra and Mede.
