Thomas Aquinas

Introduction: Ethical living is a lifestyle in which all areas of human existence and work are formed and flow around ethics. That is, a person who wants to live morally, in all areas, tries to know the ethical considerations related to that area and follow them in practice and live according to them. The current article is research on the moral system of Thomas Aquinas with a focus on examining the nature of the moral goal of human life and the moral rationality of such a life. Material and Methods: The present review study examined bioethics from the perspective of Thomas Aquinas in a descriptive manner. In order to achieve this goal, articles related to research keywords from Thomson Information Institute, Science Direct and Pub Med were examined and books related to the views of Thomas Aquinas were studied. Conclusion: The results of this study show that according to Thomas Aquinas's view on man, becoming like God and realizing God's image in material life and seeing God in the hereafter is the moral goal and eternal happiness of man. Also, Thomas Aquinas believes in the moral rationality of such a life from both perspectives - having a reason to live morally and the usefulness of such a life.

Aristotle considers metaphysics a science that discusses being qua being (or "being insofar as it is being") and its essential attributes. Alongside "being qua being," he also speaks of absolute being. The multiple meanings of "being" in Aristotle's thought have led interpreters to diverse understandings of what Aristotle truly meant by "being qua being? "They would have disagreements. A disagreement that starts from ontology and impacts their theology. Among Muslim philosophers, Avicenna and Averroes (Ibn Rushd), and among Christian philosophers, Albert the Great(Albertus Magnus) and his student Thomas Aquinas, have commented on this matter. In Avicenna's view, what is meant by 'being qua being' is a universal concept that applies to all beings, including the Necessary Existent per se. Consequently, the Necessary Existent is part of the subject matter of philosophy. However, Averroes introduced the highest substance to explain "being qua being" and considered God the subject of philosophy. Consequently, he regarded the proof of God as part of the problems of natural science. In Albert the Great's view, "being qua being" is the simple existence as the first creation of God, and this simple existence is the subject of philosophy. In Thomas Aquinas's perspective, "being qua being," although the subject of philosophy, applies only to contingent beings, and God is the cause of this "being qua being." A comparative study of these disagreements and the reasons behind them forms the framework of this article.
