Principiality of Reductionist Union and Principiality of Perfection-Based Union between Soul and Body

In the present article, at least, two correlative objectives are searched for. At first, the author will try to present a contemporary reading, as a model, of the main approach adopted by the Peripatetic philosophical tradition concerning the relation between the soul and body; in other words, a reading which is more abstract than Sinean, Thomist, and Aristotelian ones. This model will be discussed under “Principiality of Perfection- Based Union”. The second objective searched for here is a comparison between capacities of this model on the one hand and those of union based on ontological reduction. In this article, the author has tried to show that both reductionist and perfection-based approaches may be classified under the idea of “principiality of union”; concerning questions of the existence of soul, however, reduction and elimination are two sides of the same coin. It seems, however, that the main and common problem with all versions of ontological reductionism- apart from those mentioned in this article under “comparative study”- is that the idea of reduction has been overshadowed by the idea of elimination and, consequently, the union resulted from reduction will be followed by denial of a part of what that intuitionally seems to be real which is a high cost.
