reason as the source of thinking about the duality of reason and natural justice in the foundation of validity of the legal rule

highlighting the driving cause and its strict relationship with the formal cause and especially the final cause in the intrinsic elements of natural justice has caused the duality of reason and natural justice in the thinking of the proponents of the reason as the source. since the same emphasis makes the full understanding of the mechanisms of natural justice and its content for the human wisdom impossible. for this reason, one cannot speak of monism of reason and natural justice. duality refers to god-based monism, at the foundation of the legal rule, as well as the inability to present a criterion for assessing the validity of the content of the legal system. thus, the reason decreases to the reason as the source; a reason which is limited to the incomplete understanding of the natural rule and cannot create the rule of behavior.
