A study of moral and legal obligations in the thought of the late Mehdi Haeri Yazdi

In this article, moral and legal requirements in terms of semantics, ontology, epistemology, logical issues, and the relationship between them from the perspective of the late Haeri are examined. Many scholars have examined Haeri's view of the moral must, but his views on the legal must and the relationship must be moral and legal have not been examined. From a semantic point of view, he considers morality requirements as a means of non-essential necessity, and he considers a legal requirement as a means of credit necessity; From an ontological point of view, he considers morality requirements as the real relation between doer of moral action and action, but he considers law requirements as a credit derived from the construction of reason to achieve social order and justice. Epistemologically, he considers moral and legal statements to be predictive, but the preceptor for conformity with reality is considered to be the moral requirements of human wisdom and the legal requirements of common sense, which are formed on the basis of collective will in order to achieve social order and justice. In logical discussions, by delivering sentences that contain moral requirements and legal requirements to predicative sentences, he transforms the subject of should and existence into a relationship of existence and existence and considers this relationship in argumentative ethics. It seems that the lack of separation of semantic issues from ontology in the late Haeri's point of view has caused a mistake in the semantics of requirements, and the lack of a complete way of explaining ontology requirements and the way of revelation recognizing in the epistemology of law requirements is deficiencies of his point of view, Paying attention to them will be useful for the relative impact of ethics on rights.
