Manifestation of the Ethical Practical Reason in Ethical Deed

We can call practical reason, ethical practical reason because it understands ethical practical proposition. Reason independently understands goodness and badness of some deeds and on this base, creates some ethical practical propositions. For example: ‘justice is good’ and ‘injustice is bad’ are two propositions of ethical practical reason and are the fundamental laws of ethics. Another way to understand the goodness and badness of deeds is to get help from the Divine law; yet this help is not in conflict with the rationality of goodness and badness. Allameh Tabataba’i believes that for the formation of any optional action, there are some intermediate understanding and thoughts between human’s nature on the one hand and it's natural and genetical properties and effects on the other hand; these thoughts are first made by nature and then nature displays its effects and properties in the world by their aid. This article will try to present a solution to transfer us from (understanding) ethical propositions of practical reason to ethical deeds.
