  1 - Principiality of Existence and Change in the Logic of Definition

  One of the main concerns of Aristotelian logic is to find a way for defining quiddities in order to attain a conceptual knowledge of them. Aristotle founded his system of logic of definition in harmony with his own worldview. In this system, true definitions were divided into term and description. After Aristotle, the logic of definition was accepted by philosophers and logicians in its same primary form for a long period. Muslim Peripatetics followed almost the same trend until, in the course of the development of philosophy in the Islamic world, Mulla Sadra established the School of the Transcendent Philosophy through explaining and demonstrating the principiality of existence as well as developing some other ontological principles. One of the specific features of the Transcendent Philosophy was to harshly challenge the ontological bases of the logic of definition. Based on the theory of the principiality of existence, quiddities which, according to early philosophers, represent the objective reality of things, are reduced to mental concepts, and existence, which is the objective reality of things, cannot be perceived unless through direct observation. On the other hand, in this system, differentia, which is the basis of each quiddity and is considered to be the whole truth and actuality of each object, is not a quiddative thing and cannot be known through quiddative concepts. In this way, the basis of the five universals as the underlying foundation of the logic of definition became unstable. Following such changes, we expect to witness a fundamental review of Aristotelian logic and, particularly, of the concept of definition therein. The outcome of this overall change would be nothing but attaching more importance to the conceptual definition of truths, which is one of the significant consequences of the theory of the principiality of existence.

  2 - A Study of Mulla Sadra’s Ultimate View of the Meaning of the “Mentally-Positedness of Quiddity”
  Seyyed Shahriyar  Kamali Sabziwari

  In Mulla Sadra’s works, two different meanings are provided for the “mentally-positedness of quiddity”. In the first one, it means the subordinate realization of quiddity through existence. However, in the second one, it means the mental and virtual existence of quiddity in the outside. In this paper, the author suggests three hypotheses as potential strategies in order to attain Mulla Sadra’s ultimate view regarding the meaning of “mentally-positedness of quiddity”. Finally, through the confirmation of the third hypothesis, he concludes that the first meaning of this concept is not acceptable because of its rational defects and argues that only the second meaning can be considered as the one intended in the Transcendent Philosophy.

  3 - Range of the Interpretations of Quiddative Concepts Based on the Principiality of Existence in the View of Contemporary Commentators of Sadrian Wisdom
  Rohollah Adineh Roghayeh Mosavi

  The principiality of existence and mentally-positedness of quiddity are the main bases of Mullā Ṣadrā’s philosophy and his particular theories. On the other hand, he has not provided a clear and accurate picture of these two theories in his philosophical system and has referred to quiddity using different terms. Each of the contemporary commentators of the Transcendent Philosophy have interpreted quiddity and existence in a way based on their own views and theoretical principles and have tried to predicate it on Mullā Ṣadrā’s theory. However, given the fundamental role of quiddity and quiddative concepts in gaining acquired knowledge, disagreement in the interpretation of quiddity will affect the quality of explaining acquired knowledge. Hence, following a descriptive-analytic method, the present study aims to provide a correct interpretation for quiddity from the viewpoint of contemporary commentators of Sadrian philosophy and, then, investigate whether our acquired knowledge of existents, which is attained through quiddative concepts, is positive or negative. Accordingly, the authors have examined and criticized such commentators’ interpretations of quiddity and the way it explains existence. A short answer here is that, apparently, based on the correct view, which belongs to Professor Javadi Amuli, quiddity is the manifestation of determined existence, and quiddative concepts speak of limited existence, which is clearly a positive rather than a negative and purifying statement.

  4 - A Review of Mullā Ṣadrā’s Responses to the Problem of the Necessity of Subsuming One Quiddity into two Categories in the Discussion of Mental Existence
  Mohammad Hadi  Tavakkoli

  Based on the theory of the qualitative nature of knowledge and the identity of mental and objective quiddities, the acceptance of the theory of mental existence poses the problem of the necessity of the inclusion of knowledge in two categories. In his works, Mullā Ṣadrā has tried to solve this problem through distinguishing between common and primary predications, application of two categories to knowledge from two essential and accidental aspects, negation of the subsistence of inherence, and acceptance of the application of two categories to cognitive form due to the mentally-positedness of quiddity, and the possibility of its shadow-like realization in the form of multiple existences. Although a study of his responses indicate their incompleteness in resolving the issue, his principles have paved the ground for accomplishing this task through accepting the “predication of the indicator on the indicated”. According to this view, regardless of what the nature and category of the cognitive form is, the narration of the nature of an external thing is introduced as the ontological attribute of the cognitive form, which has nothing to do with its nature and is, rather, outside the realm of categories. Through this solution, we can both maintain the correspondence between the cognitive form and the nature of the external thing and, while accepting the realization of the cognitive form in the mind, resolve the problem of the necessity of the inclusion of knowledge in two categories.

  5 - A Critical Study of Suhrawardī’s Method of Defining Things
  Mohammad Hosseinzadeh
  20.1001.1.15600874.1401.28.2.5.0

  Suhrawardī has leveled five criticisms in order to demonstrate the inefficiency of the Peripatetic theory of definition and, in return, has suggested another method for defining things. This method, which is known as the “conceptual definition”, is based on a common sense understanding of the meanings of words. According to this method, words are defined through providing their conceptual bases in the view of linguists or the people of language. Here, the author firstly explains Suhrawardī’s method of defining things and then examines it critically. The critical analysis of his view reveals that the logical conclusion of his criticism of the Peripatetic theory of definition is the correction of this theory through employing intuition rather than leaving the definition of things based on their quiddity aside and advocating the theory of conceptual definition. Moreover, Suhrawardī’s theory of definition, as a replacement for its Peripatetic counterpart, suffers from several problems. Therefore, even if Suhrawardī’s objections to the Peripatetics’ theory of definition are accepted, his own method in this regard is not acceptable by itself. At the end of this paper, the author explains and criticizes the views of a contemporary researcher of Suhrawardī’s ideas who believes that the relationship between Ibn Sīnā’s and Suhrawardī’s logic of definition is one of completion rather than difference.

  6 - Problem of Attributing Quiddity to Existence in Seyyed Ṣadr al-Dīn Dashtakī and an Evaluation of Mullā Ṣadrā’s Narration of his Views
  Seyyed Ahmad  Hosseini Sangchal

  Solving the problem of attributing quiddity to existence in Dashtakī’s view is intertwined with the theory of predication, derivative, and the principle of subordination. Through separating existence in the sense of being in existence and existence in the sense of existent and distinguishing accidents by-themselves from mentally-posited accidents, Dashtakī has analyzed the problem of attribution in line with the pre-supposed elements. He agrees with the occurrence of existence to quiddity only in existence in the sense of existent in the mind. Mullā Ṣadrā has usually provided an incomplete narration of Dashtakī’s view of attribution, theory of predication, derivative, and the necessity of demonstrating the source of the predicate for the subject. In fact, he has explained all the related elements in one place. In his analysis of the subordination principle, he is completely influenced by Dashtakī. It seems that, in spite of his great efforts at providing a consistent narration of Dashtakī’s view, Mullā Ṣadrā has failed to present some elements consistently in his own theory. Manuscript profile
