Abstract

This study, drawing on Aristotelian essentialism the view that every being possesses an essence with intrinsic properties argues that the development and actualization of the human being, as one being among others in the world, are grounded in his essential nature, namely rationality. This essential nature inclines human beings toward the pursuit of the good, which is recognized as the final cause (telos) of the actualization of their essence. Moreover, human choices are not detached from the beings of the world. Rather, the objects of moral good and evil are the very entities and essences that exist in reality. Moral judgments, therefore, concern these concrete and real beings; they shape human actualization and take part in the causal order of the world. Therefore, since the actualization of beings is inseparable from their essences, the creator of the essences of the world and the legislator of moral laws must be one and the same. In the course of this study, we arrive at the conclusion that every doctrine other than religious moral realism ultimately confronts some form of relativism. Even moral relativism, insofar as it claims to endorse realism, is incapable of providing a foundation for an absolute and objective higher good. Accordingly, through rational inquiry and on the basis of Aristotelian essentialism, the possibility of discovering reality for human beings is established, along with the justification of moral realism and, ultimately, the compatibility of moral realism with the foundations of theistic monotheism.
