Abstract

The analysis of conditional propositions is one of the most important logical issues. It seems that the linguistic analysis of the propositions, regardless of the facts that the propositions they indicate to, is not a complete analysis. By relying on the knowledge of the realities of the universe and their categorization makes the way easy for understanding the propositions which are indicated from them. The late Khaje Nasir by drawing a chart in Asas al-Eghtebas book has calculated aspects of connection and has shown what each of the four quantified propositions, whether essentiality, accidental, or presumption of a present fact, is used to express what kind of connection it is and from this chart, negative connective conditional proposition application cases has been known. The image provided by this chart appears to have some drawbacks in the available versions which in this paper, while explaining the types of connections between the two objects and how they are illustrated by conditional propositions, a correct picture of the chart is presented.
