چکیده مقاله

Aristotle’s view regarding the emptiness or non-emptiness of the terms of propositions has been interpreted in two ways. In one of them, the terms of propositions always include an existing individual or some existing individuals and are non-empty. Therefore, in negative propositions, the collection of the individuals of the subject is never an empty collection either. Hence, there is no difference between negative and affirmative propositions regarding the necessity of the existence of individuals for their subjects. According to the other interpretation, in any proposition, whether negative or affirmative, its components should be first conceived and come into being through a mental existence. Then, if the proposition is an affirmative one, in addition to this mental concept, there should be an existing or supposedly existing individual to receive an affirmative judgment. However, in case of a negative proposition, except the mental existence of the proposition, which is necessary for passing judgment, there is no need for an existing or supposedly existing individual to receive the predicate attribute. Hence, there is a difference between affirmative and negative propositions in this regard. In his interpretation of negative propositions, Khwajah Nasir Tusi has paid attention to both aspects and considered each of the two interpretations to be correct in its own right. The first interpretation is ruled as a correct one given the propositions which are used in different sciences – and these propositions always depend on external truths. Moreover, the second interpretation is correct due to the absoluteness aspect of negative propositions, and also because a non-existent entity cannot be qualified with any quality, including the predicate attribute, since it is non-existent.
