Existence and Ethics from the Viewpoints of Allameh Tabatabaee and Dr. Mehdi Haeri Yazdi

One of the issues which has been raised recently in the Muslim community and has led to the emergence of different theories is the relationship between ‘delineation and obligation’ or ‘science and value’. With regard to this، proposing hypothetical perceptions، Allameh Tabatabaee draws a distinction between ethical propositions and existential or true propositions. Therefore، he believes ‘what explicitly exists’ can influence the authenticity of ethical propositions. However، he doesn’t clarify how such propositions can be deduced. Mehdi Haeri Yazdi، on the other hand، holds that ethical propositions and true propositions are from the same ilk. He believes ‘does and don’ts’ of ethical propositions are a manifestation of necessity in which there is nothing but existence and emphasis. In addition to explicating the views of these two thinkers، the present article evaluates their thoughts and discloses their strengths and weaknesses.
