        1 - A Critical Study of Seyyed Sharif Jurjani’s Reasoning Regarding the Simplicity of the Derivative
        Seyyed Ahmad  Hosseini Sangchal Mohammad Saeedimehr

        The problem of the simplicity or combination of the derivative is one of the controversial issues which, in spite of its similarity to mentally-posited discussions, has sometimes affected philosophical debates. The present paper reports on the results of a critical study of Jurjani’s reasoning regarding the simplicity of the derivative. In his view, whenever the derivative is assumed to consist of “shayin lahu …”, in case of attaining the concept of “shay”, interference of general accident in differentia occurs. However, in case of attaining the extension of “shay”, the transformation of the possible proposition through the necessary happens. In the first case, the differentia fails to be a differentia, and in the second case the direction of possibility is removed from the world of reality. In order to explain the quality of the transformation, a solution has been presented which analyzes the concept of portion and the role of limitation and determination in the predicate. Here, the writers, in spite of considering this argument to be perfect, clarify that the given reason for demonstrating the simplicity of the derivative is inefficient and is only capable of deriving the concept or referent of “shay” from the truth of the derivative.

        2 - An Analytic Study of Motion in Mulla Sadra and Neo-Sadrian

        The issue of motion in philosophy has been discussed from different angles. One of them is the discussion of the existence and survival of the subject of motion, particularly, in the trans-substantial motion, which was viewed as one of the concomitants of motion and one of the elements of its individuation in pre-Sadrian philosophies. Through presenting his innovative principles, Mulla Sadra transformed the view of motion and its concomitants, including the subject of motion, to a large extent. The problem of motion in the trans-substantial motion has always provoked controversial debates and conflicts in Mulla Sadra’s philosophical school and among neo-Sadrians. In certain cases, Mulla Sadra emphasizes the need of trans-substantial motion for a subject, and in some other cases he overlooks it. The same point has always created some conflicts among the advocates of Sadrian school, including ‘Allamah Tabataba’i and Mutahhari. In this paper, while investigating different views and their strengths and weak points, the writers conclude that the trans-substantial motion does not need a subject; rather, motion in accidents is also needless of its subject. They also maintain that, given the Sadrian principiality of existence, one can support a single fluid existence in the real world which is by itself the same as motion, the mover, and the moved, and that distinguishing them from each other would only be possible through analysis.

        3 - A Study of Ibn Sīnā’s Argument on the Accidental Nature of Unity in Ilāhīyyāt al-Shifā’
        Mihammadhadi Tavakoli
        According to Aristotle, a number of philosophers in ancient Greece theorized that the “one” is an independent substance that performs a causal role in relation to other substances. Through clarifying the predicative nature of the “one” and referring to the false consequ More
        According to Aristotle, a number of philosophers in ancient Greece theorized that the “one” is an independent substance that performs a causal role in relation to other substances. Through clarifying the predicative nature of the “one” and referring to the false consequences of the above theory, he tried to reject it. Ibn Sīnā has extensively investigated the theory of the one’s being a substance and Aristotle’s related criticisms in the ilāhīyyāt section of al-Shifā’. Unlike Aristotle, he has not merely referred to the one’s being a predicate and, rather, through a lengthy and complex argument, has tried to demonstrate that unity, as the source of the derivation of the one, is a necessary accident. Ibn Sīnā’ argument is prone to criticism from different aspects, the most important of which is the confusion of categorical and analytic accidents with each other. Unity is merely an analytic accident, and Ibn Sīnā’s argument is incapable of demonstrating its being a categorical accident. Manuscript profile

        4 - Explaining Horizontal Pluralities in the Vertical Worlds of Existence Based on Sadrian Philosophy
        Ali Sedaghat Hasan Fathzadeh
        Based on the principle of the gradation of existence in Sadrian philosophy, the world of being enjoys a vertical system that extends from the highest point to the lowest levels, and each existent possesses a specific degree of existential intensity and weakness. The acc More
        Based on the principle of the gradation of existence in Sadrian philosophy, the world of being enjoys a vertical system that extends from the highest point to the lowest levels, and each existent possesses a specific degree of existential intensity and weakness. The acceptance of this principle in Sadrian philosophy alongside one’s observations in our surrounding world of horizontal existents with no cause-effect relation, such as a stone and a tree, gave rise to an important question in the post-Sadrian period: How can these two truths come together in one place? The responses to these questions during the last 400 years have resulted in some disagreements among commentators of Mullā Ṣadrā’s works. In this study, the authors aim to demonstrate that the acceptance of the vertical and graded system of existence is not in conflict with accepting horizontal pluralities, and what is accepted in Sadrian graded existence is a differential system among all existence and not merely a cause-effect system. The key to the understanding of horizontal pluralities in Sadrian philosophy must be found in the discussion of archetypes and their additions. In presenting his own system of emanations, Mullā Ṣadrā has been greatly influenced by Suhrawardī’s philosophy and defended the quality of the emanation of archetypes at different occasions. Archetypes are the same horizontal intellects the acceptance of which is equal to resolving the problem of horizontal pluralities in all vertical worlds of existence. Manuscript profile
