His intention of the word argument is the a priori argument, also known as absolute argumentation. In the article at hand, firstly the various types of arguments and their epistemological values are discussed and then, Avicenna’s stance toward the irrefutability of God’s existence and his reasons are examined. This analysis reveals that not only Avicenna’s proof of the righteous is an a priori argument, but also the creature-oriented arguments, in which the created is used to argue for the creator, are a priori arguments based on the accepted principles of logic. Since these arguments do not directly prove the existence of God, they are essential a priori arguments with regard to their own outcome, and are accidental causal arguments with regard to the existence of God. %U https://jpht.ut.ac.ir/article_69988_654263055b0a556936201a14d79eb657.pdf
