Abstract

This article is devoted to the study of the nature of copula and the ways to recognize it. It also aims to provide an answer to the question of whether there is anything in this world which is free from any kind of relation and belonging.Those who have a realistic view of this world reply that what is exposed to man's thought inevitably enjoys some kind of relation. The reason is that if we can conceive of an existent free from any kind of relation, that existent undoubtedly becomes a part of our knowledge and requires a kind of relation between the knower and the known.Islamic philosophers have divided existence into two types: copula and dependent, and the issue of the relation between the subject and the predicate has raised a great number of discussions among researchers.In Mulla Sadra's Transcendent philosophy all the existents of the possible world, from the sovereignty to the dominion, are the same as relation and have absolute dependence upon the Truth.The existence of a relation could be dependent on both sides or it could be dependent on one side. It should be taken into consideration that the relation, while being a reality, is not capable of having an independent existence. In Mulla Sadra's opionion, the world of possibles has a kind of illuminative correlation with the absolute being of the Truth.
