The separation of Avicenna between Essence and Existence influenced logic and Arab and Muslim logicians in the Middle Ages among them Ibn al-Nafīs (1208-1288). Under this influence he contributed to the development of logic and especially the theory of the universal term. By means of the consequences of this analysis:-It has become possible to make a distinction between abstract concepts and formal concepts independent of any sensible reality, and hence the questioning of Aristotelian categories, that is to say the ability (...) to conceive for Ibn al-Nafīs like Avicenna, subjects and predicates which are not necessarily words expressing or belonging to one of the Aristotelian categories.-The analysis of the universal proposition as a conditional proposition, which made easier the distinction between absolute proposition which has no existential implication, and the other which differ from the first by an affirmation of explicit existence.

If all things and events, including human actions, are predetermined by God since pre-eternity, then what space is left for human freedom of will, and hence, for moral responsibility? In the beginning of the 14th century, a non-Muslim scholar, probably of Jewish faith, confronted several Muslim scholars from Damascus and Cairo with precisely this question in versified form. Among them is the well-known Ḥanbalī theologian and jurist Ibn Taymiyya (d. 728/1328), who is said to have responded instantly with a 184-verse (...) poem (of which 125 verses are extant). This article provides an analysis of Ibn Taymiyya’s stance on the question of how it can be said that God is just in predetermining and judging human actions and compares it to that of Faḫr ad-Dīn ar-Rāzī. The article ends with the first full translation of the versified question and Ibn Taymiyya’s response into a European language. Both thinkers depart from similar positions, insofar as both deny human free will. However, while Ibn Taymiyya tries to show that the fact that God will hold human beings accountable for their predetermined actions does not go against our inborn sense of justice, ar-Rāzī adduces that fact as part of his strategy to show that God’s actions cannot be subject to rational moral assessment, as they would otherwise have to be declared as senseless and even harmful.

The passionate and staunch defence of logic of the controversial thinker Ibn Ḥazm, Abū Muḥammad ʿAlī b. Aḥmad b. Saʿīd of Córdoba (384-456/994-1064), had lasting consequences in the Islamic world. Indeed, his book Facilitating the Understanding of the Rules of Logic and Introduction Thereto, with Common Expressions and Juristic Examples (Kitāb al-Taqrīb li-ḥadd al-manṭiq wa-l-mudkhal ilayhi bi-l-alfāẓ al-ʿāmmiyya wa-l-amthila al-fiqhiyya), composed in 1025-1029, was well known and discussed during and after his time; and it paved the way for the studies (...) of his compatriots Ibn Bājjah (d. 1138), Ibn Ṭufayl (1185), and Ibn Rushd (1198), who each gave demonstrative reasoning a privileged place within the methods of attaining knowledge. Unfortunately, as too often in the history of science, Ibn Ḥazm’s innovative perspectives and contributions in logic have been overlooked or considered with an attitude of contempt. On the one hand, his work has been seen, at best, as promulgating the benefits of studying Aristotle’s logic, so that his contribution is assessed as more didactical than conceptual. And on the other hand, those who do examine his innovations often consider them to be mistaken. As indicated by Chejne (1984, p. 2) contempt towards the logical work of Ibn Ḥazm was also present in its reception by the Eastern philosophers who accused him of deviating from Aristotelian logic and of dabbling in things beyond his capability. However, a reassessment of his work on logic has since begun, by delving into the ways the thinker of Córdoba studied the links between deontic and modal qualification of propositions. In this context Lameer’s (2013) paper on the logical sources of Ibn Ḥazm is worth mentioning; the author (p. 417, footnote 1) observes that, although, strictly speaking, it was al-Fārābī who first drew the parallelism between deontic and modal concepts, it was Ibn Ḥazm who developed it and worked it out in a more precise manner. A primary aim of this paper is to help fill some of these gaps by stressing the role of the work of Ibn Ḥazm in developing a notion of deontic necessity deeply rooted in legal normativity, and in explicitly discussing the transference between deontic and modal concepts. According to our view; the basic units of Islamic deontic logic are what we might call, indulging in terminological anachronism, heteronomous imperatives. As it turns out, the heteronomy of imperatives within Islamic legal systems contrasts with those of the purely moral realm, which seem to be closer to an autonomous conception of moral law. There it concurs again with Leibniz’s proposal to define obligatory as “what is necessary for a good person to do”. In the present paper, we will focus on the heteronomous imperatives of legal systems rather than on the imperatives of the purely moral realm. In this context, the work of Ibn Ḥazm extends the parallelism between the necessity of events and that of human actions stressed by his predecessors. According to our understanding, Ibn Ḥazm’s parallelism can be rendered explicit formally by means of a conditional (or hypothetical) structure shared by both deontic and modal propositions. Moreover, this structure makes apparent that this parallelism displays an underlying system of “degrees”. Indeed, while in the domain of events, given some conditions, it makes sense to distinguish between an event that is more likely to happen than another. Ibn Ḥazm speaks of near and distant possibility (such as the higher degree of likelihood of rain, given the condensation of clouds in December, and its lower degree, when the condensation occurs in summer); and, in the domain of actions, the Islamic notion of weighting actions determines degrees of virtue (or of legal and moral value). So whereas the degree of virtue of performing a forbidden act as determined by the distribution of sanction and reward is 0, we obtain the same value by pondering the likelihood of an impossible event to take place. Furthermore, as discussed in section II.3.2, the system of values at work in the parallelism can be seen as opening the way to a more direct correspondence. Thus, while in the realm of nature, likelihood of occurrence of an event is dependent upon the conditions specific to the occurrence of that event; while, in the realm of jurisprudence, likelihood of performing an action is dependent upon the distribution of reward and sanction specific to that action (being that, given the choice to perform or not perform a given action, those that will be rewarded are more likely to be performed than those that are not). According to this perspective, the point of the parallelism is that both deontic and modal qualifications measure the degree of an action or event to become actual; that is – indulging once more in anachronism (but this time from the Leibnizian background) – the degree measures how feasible (facile) an action or event may be. This suggests that Ibn Ḥazm’s perspectives already herald the links to probability and possibility explored by Leibniz six centuries later – see for example Leibniz’s (1671, A VI, I, p. 424-26) use of probability in the context of conditional right. Nevertheless, it also shows a crucial difference to the approach developed in the Elementa Jura Naturalis: whereas Leibniz’s studies seek to define what is to be just or virtuous, the logical system of deontic imperatives within Islamic jurisprudence presupposes that what is to be virtuous has already been settled. Determining what is to be virtuous is not achieved by logical reasoning within the system of legal jurisprudence, but by delving into the higher objectives of the Sharīʿa. While developing our point, we will delve into the logical structure of the heteronomous imperatives. This distinguishes our contribution from the existing literature, such as the papers of Chejne (1984), Lameer (2014), and Guerrero (1997, 2010, 2014), which do not provide a logical analysis of the deontic concepts put into work by Ibn Ḥazm. The true antecedent to the present paper is the work of Farid Zidani (2007, 2015), who, so far as we know, was the first to undertake such a task. Some of our own developments and general epistemological thoughts go beyond Ibn Ḥazm’s framework and motivations; mainly those contained in sections II.3.2 and IV. However, according to our view, these reflections suggest that Ibn Ḥazm’s approach has the substance for a broader and deeper exploration of the logic of norms. The paper is structured as follows:I.Ibn Ḥazm’s Logic of Heteronomous Imperatives. After presenting some extracts of the relevant text, we proceed by providing a formal reconstruction of the five forms of deontic modalities. II. A Landmark in the History of the Logical Analysis of Norms. Duties and Modalities. In this section, we study the transferences from deontic to modal necessity and possibility. We briefly compare the deontic system of Islamic Jurisprudence with that of Leibniz.III. Leibniz and Hypothetical Imperatives in Law.IV. Beyond Ibn Ḥazm: Conclusions and the Work Ahead. We will conclude the paper by discussing briefly some conceptual points that distinguish the logic of heteronomous imperatives from contemporary deontic logic. Our final words will discuss deontic-modal parallelism in the context of Ibn Ḥazm’s rejection of reasoning by conjecture and what we call “the internalization of nature.”. (shrink)

The tradition of Lughz and muʿammā in Arab poetry has an important place. Ibn al-Fāriḍ (d. 632/1235) is a divine love poet that lived in the Ayyubids period. He is an important point in the process of change and transformation of Arabic poetry language. This research aims to carry out a theoretical and anecdotal examination of the Lughzes in Ibn al-Fāriḍ’s Dīwān. The work explains, firstly, the concept of Lughz in terms of conceptual content and theoretical structure and summarizes its (...) own method to be applied in solving and evaluating Lughzes in ten articles. The paper indicates whether the Lughzes in Dīwānhave a theoretical structure or not. In this context, it distinguishes the Lughzes from the number of layers, simple and compound structure maintenance. It examines the theoretical and functional contributions of the tahsīl, takmīl, tashīland tazyīlmethods, the stages of the establishment and the solution of the Lughzes.Abstract: Abū Hafs Sharafuddīn Omar b. Ali al-Hamavī al-Mısrī (d. 632/1235) known as the king of lovers, and called Ibn al-Fārid, is a divine love poet that lived in Egypt during the Ayyubids period (1171-1462). He is an important figure in the process of change and transformation of poetry language in Arabic literature. The lughz and muʿammā (enigma, enigmetic speech, allusion, inversion riddle, poetry puzzle, synecdoche and metaphoric language) means a word pointing to a name or something by symbol and sign. Numerous books have been written about lughzes. These include Arabic poetry, Persian poetry, Classical Turkish poetry, Arabic grammar, Islamic law, hadith, mathematics and inheritance law. The lughz and muʿammā have some linguistic features related to phonetics, statistical linguistics, morphology, lexicology, grammar, syntax, semantics and prosody. This tradition has an important place in Arabic poetry. The research aims to carry out a theoretical and anecdotal examination of the lughzes and muʿammās in Ibn al-Fārız’s Dīwān. The paper explains, firstly, the concept of lughz in terms of conceptual content and theoretical structure. The article summarizes its own method to be applied in analyzing and evaluating lughzes within ten items. The research examines the series of lughzes in Dīwānand divides them into parts according to the original question in the riddles. This work examines the secondary lughzes given in the details of poems in solution parts. The paper indicates whether the lughzes in Dīwānhave a theoretical structure or not. In this context, the research examines lughzes in terms of language and structure, especially in terms of the processes of establishment and solution. This paper categorizes the lughzes according to the number of layers and to whether they have a simple or compound structure. This paper examines the theoretical and functional contributions of the amal al-tahsīlī, amal al-takmīlī, amal al-tashīlī and amal al-tazyīlī methods in the stages of the establishment and the solution of the lughzes. The work applies the theoretical perspectives of these methods to each lughz. The research also examines the contribution of these four methods to the lughzes.There are many lughzes in Ibn al-Fārid’s poems. In Ibn al-Fārid’s Dīwān, in general, fifty-four things are asked. Fifty-one of them are words. Three of them are verbs. One of the verbs is in the order structure and two in the past tense. His lughzes have a theoretical and methodical structure. In terms of organizational structure, lughzes are generally multi-layered, intricate, compound and integrated. Composite lughzes are multi-layered, simple poems are single-layered. Approximately twenty words are asked in the lughzes. These words are always in the first layer of lughz, whether simple or compound. Thirty-seven words in the lughz are secondary lughz with an auxiliary and complementary nature. They are located between the second and sixth layers. Seventeen of the lughzes asked in the auxiliary nature are located in the second layer, thirteen in the third layer, five in the fourth layer, one in the fifth layer and one in the sixth layer. One of the lughzes is six-layered, one of them are five-layered, four of them are four-layered, eight are three-layered, four are double-layered and three are single-layered. According to this, the majority of lughzes in Ibn al-Fārid’s poems are in the unified form and multilayered.The lughzes are formed in terms of word, composition, phrase, grammar and meaning levels. The lughzes have both lexical and semantic characteristics. Ibn al-Fārid uses the configuration (amal al-tahsīlī), completion (amal al-takmīlī), facilitation (amal al-tashīlī) and addition (amal al-tazyīlī) methods to design the lughzes. The structure in the lughzes is shaped by these methods. The words in his lughzes constitute eleven categories, consisting of names, acts and noun verbs. The answers of the questions asked in the poems consist in general of prophet names, surah names, tribal names, administrator’s surnames, letters, cities, animals, food and drink names, attributes and actions. Verbs are in the past time or order form. Some of the lughzes in Ibn al-Fārid’s poems are built in an extraordinary style beyond being interesting. Not all the sentences used in couplets are part of the lughzes. These elements are mentioned in order to complete the lughzes in terms of rhythm and meaning. To be able to solve the lughzes of Ibn al-Fārid, one must be knowledgeable about the language and narrative features of Arabic and Islamic culture, as well as subjects such as the Quran, Sufism, abjad calculation, mathematics, geometry, geography, biology, botany and zoology. His poems contributes to the development and transformation of Arabic poetry. (shrink)
