Re-reading of the Rule of Al-Wahid inHesiod's Theogony

In the present article, one of the most famous rules of Islamic philosophy in Theogony written by Hesiodis considered. We assume that there is a historical connection between mythical and philosophical thoughts, and mythical concepts have been developed in passage of time. Then and after a cursory examination of the rule of Al-Wahid (exuno non fit nisi unum, only one can come from one), we examine Theogony based on the mentioned rule. In that book with regards to genealogy of gods and the relationship of parents and children,a primary understanding of the principle of “same cause, same effect” and “reduction of plurality to unity”can be recognized. Also, simplicity and undeterminateness of the first cause can be re-examined and re-recognizedin Hesiod’s book.
