Recently, Quyn et al. demonstrated that cells within the stem cell zone of human and mouse intestinal crypts tend to align their mitotic spindles perpendicular to the basal membrane of the crypt. This is associated with asymmetric division, whereby particular proteins and individual chromatids are preferentially segregated to one daughter cell. In colonic mucosa containing a heterozygous adenomatous polyposis coli gene (APC) mutation the asymmetry is lost. Here, we discuss asymmetric stem cell division as an anti‐tumourigenic mechanism. We describe how (...) hierarchical tissue structures suppress somatic evolution, and discuss the relative merits of template strand retention to limit the accumulation of DNA replication errors. We suggest experiments to determine whether somatic mutations resulting in loss of spindle alignment confer an advantage within the stem cell niche. Finally, we discuss whether lack of spindle alignment constitutes an oncogenic event per se, with particular reference to studies in model organisms, and the timing of chromosomal instability in human cancers.

RésuméEst-il possible d'inventer une science qui définit les règles d'un débat éthique, logique et efficace? Shams al-Dīn al-Samarqandī, un logicien et juriste Ḥanafite, a jugé une telle entreprise possible. Il a assumé la tâche de développer une théorie générale de la discussion scientifique qui a eu un énorme succès dans les cercles d’études dans le monde musulman. Il a appelé la nouvelle discipline Ādāb al-baḥth wa-al-munāẓara, un ensemble de principes éthiques et logiques, empruntés à la logique aristotélicienne et à la (...) dialectique juridique musulmane. Son traité majeur, Risālat Ādāb al-baḥth, a initié une nouvelle discipline dans laquelle des douzaines de traités et de commentaires ont été rédigés. Dans cet article, il s'agit de mettre en lumière cette science négligée, de décrire sa structure, d'exposer ses fonctions et de souligner son importance pour le développement des débats et des dialogues intellectuels dans l'Islam médiéval tardif.

This article presents an analysis of a short treatise entitled Ādāb al-Baḥth wa al-Munāẓarah (The art of discussion and disputation) by the celebrated Ottoman scholar Abu al-Khayr ‘Iṣām al-Dīn Aḥmad ibn Muṣṭafā ibn Khalīl Ṭāshkubrīzādah or Ṭaşköprüzade (d. 968 AH/ 1561 CE). An overview of the nomenclature and a brief introduction about the author and his work will be presented along with an annotated English translation of the text in order to highlight Ṭaşköprüzade’s contribution to this nearly forgotten discipline.

This article places the textual production of classical Islamic law in its proper historical context. It does so by examining a transcript of an eleventh-century oral debate, or disputation, between the Shafiʿi and Hanafi jurists Abū al-Ṭayyib al-Ṭabarī and Abū al-Ḥasan al-Ṭāliqānī on the subject of the pre-emptive expiation for broken oaths. The comparison between the disputation transcript and al-Ṭabarī’s lengthy legal manual al-Taʿlīqa al-kubrā reveals that the complexity and argumentative detail of disputations far exceeded jurists’ writings. Even the lengthiest (...) legal manuals of the time are shown to be highly summarized accounts of juristic thought. The article explains how these summaries were essential to the proper training of jurists in the age of ijtihād: jurists were expected to learn these summaries before exploring the law in greater depth through disputations. These disputations were rarely recorded in writing, and few survive. The disparity between the oral and written legal discourse of jurists leads to a disquieting conclusion: much of the thought that produced classical legal opinions is lost to us today. We are therefore left with access to an attenuated version of classical law. (shrink)

Many assumptions believe that classical Islamic theology is no longer relevant in the contemporary era, either because its discussion tends to be theocentric and far from the progress of humanism or because it is considered no longer relevant to answer contemporary issues such as secularism, pluralism, globalization, or neo-atheism. Departing from these problems, efforts have emerged for new readings of classical theology by paying more attention to the context and needs of the times. Among these efforts is the renewal of (...) theology by highlighting its methodological aspects, as was done by a contemporary Moroccan theologian and philosopher, Ṭahā ‘Abdurraḥmān. This study attempts to describe and analyze the style of renewal of theology from the perspective of Ṭahā ‘Abdurraḥmān. This research is a character study using qualitative methods, in which the existing data is analyzed critically. This article shows that Ṭahā ‘Abdurraḥmān’s style of renewal of ‘ilm al-kalām focuses on efforts to reform the methodology of classical kalam by reforming the method of dialogue science (munaẓarah) through contemporary linguistic and logical tools, rearranging analogy patterns (qiyas), and building a logic of kalam based on the principle’s logic and morality as well as the amalgamation of theoretical aspect and practical aspect. The significance of Ṭahā ‘Abdurraḥmān’s renewal in contemporary Islamic theology lies in the theorizing of concepts in classical theology with a contemporary approach as well as the construction of the methodology of contemporary Islamic theology to answer ever-evolving theological issues.

Al-Abharī’s Isagoge is an introductory primer in logic which has received numerous commentaries, each geared towards students of various levels of familiarity with this instrumental science. Al-Fanārī’s advanced commentary on the Isagoge, called al-Fawāʾid al-Fanāriyya, has confounded students of logic for centuries due to its terse and dense style as well as the presumption that the reader knows well the science of disputation along with the subtle interpretive disagreements discussed in other texts and commentaries. Sājaqlīzādah’s primer on disputation entitled al-Waladiyya, (...) written nearly 300 years after al-Fanārī’s commentary, provides useful examples of the possible claims, objections, and defenses available to one making scholarly claims in the form of definitions, classifications, and propositional assents or syllogistic reasoning. In this article, I explore several instances of al-Fanārī’s use of the terms and methods of disputation in order to defend definitions or classifications found al-Abharī’s Isagoge. I aim to identify the specific disputational moves used by al-Fanārī, drawing from those described by Sājaqlīzādah. In doing so, I demonstrate that this important advanced commentary on a popular logic primer is best understood through the lens of disputation. I also argue that Sājaqlīzādah’s suggested methods of making claims, objections, and defenses can be transposed in whole or in part from one category of claim—definitions, classifications, assents—to another, indicating a greater complexity of disputational possibilities than his introductory handbook provides.

This chapter analyzes traditional archetypes of divan literature—‘āşık (lover), ma‘şūk (beloved), and rakīb (opponent)—to show the presence of a dialectical discourse in classical Ottoman divan love poems. In both style and content divan poems display a comprehensive understanding of the postclassical Islamic philosophical conception of dialectic and argumentation theory, known as ādāb al-baḥth wa al-munāẓara. The focus on Ottoman love poetry and argumentation theory in this paper aims to demonstrate how the love poetry that developed in Ottoman culture is more (...) dialectical in form and content than Ottoman literary studies have recognized.

The post-classical (or post-Avicennan, post-Rāzian) genre of the “protocols for dialectical inquiry and disputation” (ādāb al-baḥth wa-l-munāẓara) has its more proximate origins in the famed Risāla of Shams al-Dīn al-Samarqandī (d. 722/1322). The greater part of his conceptions and methodology, however, consists in a streamlining and universalizing of the more strictly juristic dialectic (jadal / khilāf) of his teacher Burhān al-Dīn al-Nasafī (d. 687/1288); and this in turn draws on the highly logicized dialectic of Rukn al-Dīn al-ʿAmīdī (d. 615/1218) and (...) his teacher Raḍī al-Dīn al-Nīsābūrī (d. 617/1220). At the heart of methods in this lineage, and carried forward by al-Samarqandī into the universal ādāb al-baḥth, are three truth-preserving logical relationships critical to the truth-seeking enterprise of dialectic: entailment (talāzum / mulāzama), mutual negation or exclusion (tanāfin / munāfā), and causal concomitance (dawarān). The practical elaboration of these relations reveals a logic in action—a premodern dialogical logic for living disputation praxis. In fact, so critical were these to the dialectical enterprise that al-Samarqandī devoted a specialized treatise entirely to summarizing their defining features and rules, aptly naming it the ʿAyn al-Naẓar, or “Wellspring of Rational Investigation.” In this article, and drawing upon a recently published digital critical edition, I will present an analytical outline of these core logical relations as presented in the ʿAyn al-Naẓar. Then I will address a number of points of interest in this text, grouped under six themes: the potential for cross-disciplinary advancement; notions in discursive development; significant or uniquely contributive formulations; peculiarities of content; signs of an evolving, universalist agenda; and evidence that the ʿAyn al-Naẓar was designed as an aide-mémoire for the active disputant.

For the communication between people to remain effective and lively and for the expressive power to be permanent, the qualities of the words are as important as the quantity of words in a language. From this perspective, Arabic has many linguistic features like other developed languages. Parsing, deriviations, blending, synonymy, contrast, arabization, antithetical polysemy, commutation, ellipsis, polysemy, etc. Language features are intensely found in Arabic. As it is known, polysemy is one of the important issues of the Arabic language that (...) has been taken into consideration since the compilation period. Although there are scholars among Arabic linguists who deny the existence of polysemous words, the vast majority have accepted the issue of polysemy. Among polysemous words, some words indicate several different meanings, as well as words that express many different meanings. In this respect, words that indicate a lot of meanings in the group of polysemous words have attracted the attention of poets. Poets wrote long odes using such words to demonstrate their mastery of the science of the dictionary and to prove their competence in the art of poetry. There are even poets who write different odes in terms of theme, using the same word. One of these poets is Ibn al-Munāṣıf from Cordoba, who lived between 1168 and 1223. The poet, better known as the jurist, wrote his famous ode using the common word "acuz". By ending each couplet with the word ʾujūz, the poet brought together the different meanings of the word ʾujūz in the ode in question. In this study, the issue of polysemy, which is considered an important feature of the Arabic language, will be briefly discussed. In addition, the Qasida of ʾUjūz will be translated and analyzed.

The Dialectical Forge identifies dialectical disputation as a primary formative dynamic in the evolution of pre-modern Islamic legal systems, promoting dialectic from relative obscurity to a more appropriate position at the forefront of Islamic legal studies. The author introduces and develops a dialectics-based analytical method for the study of pre-modern Islamic legal argumentation, examines parallels and divergences between Aristotelian dialectic and early juridical jadal-theory, and proposes a multi-component paradigm—the Dialectical Forge Model—to account for the power of jadal in shaping Islamic (...) law and legal theory.In addition to overviews of current evolutionary narratives for Islamic legal theory and dialectic, and expositions on key texts, this work shines an analytical light upon the considerably sophisticated “proto-system” of juridical dialectical teaching and practice evident in Islam’s second century, several generations before the first “full-system” treatises of legal and dialectical theory were composed. This proto-system is revealed from analyses of dialectical sequences in the 2nd/8th century Kitāb Ikhtilāf al-ʿIrāqiyyīn / ʿIrāqiyyayn through a lens molded from 5th/11th century jadal-theory treatises. Specific features thus uncovered inform the elaboration of a Dialectical Forge Model, whose more general components and functions are explored in closing chapters. (shrink)

Evolutionary approaches to the emotions have traditionally focused on a subset of emotions that are shared with other species, characterized by distinct signals, and designed to solve a few key adaptive problems. By contrast, an evolutionary psychological approach (a) broadens the range of adaptive problems emotions have evolved to solve, (b) includes emotions that lack distinctive signals and are unique to humans, and (c) synthesizes an evolutionary approach with an information-processing perspective. On this view, emotions are superordinate mechanisms that evolved (...) to coordinate the activity of other programs in the solution of adaptive problems. We illustrate the heuristic value of this approach by furnishing novel hypotheses for disgust and sexual arousal and highlighting unexplored areas of research. (shrink)

If an asymmetry in time does not arise from the fundamental dynamical laws of physics, it may be found in special boundary conditions. The argument normally goes that since thermodynamic entropy in the past is lower than in the future according to the Second Law of Thermodynamics, then tracing this back to the time around the Big Bang means the universe must have started off in a state of very low thermodynamic entropy: the Thermodynamic Past Hypothesis. In this paper, we (...) consider another boundary condition that plays a similar role, but for the decoherent arrow of time, i.e. the quantum state of the universe is more mixed in the future than in the past. According to what we call the Entanglement Past Hypothesis, the initial quantum state of the universe had very low entanglement entropy. We clarify the content of the Entanglement Past Hypothesis, compare it with the Thermodynamic Past Hypothesis, and identify some challenges and open questions for future research. (shrink)

The main idea animating the present paper is that the general aim of debates, such as the one involving the notorious case of the Master Argument, is the ponderation of logical principles by confronting them with some set of assertions and other endorsed principles on the meaning explanation of connectives, quantifiers and modality. As suggested by Seel (2017), the point of the specific case of the MA is about examining Aristotle’s notion of possibility – as implemented by the Possibility Principle (...) (i.e., If it is necessary that if A then B, then B is possible if A is) and the Possibility Rule (i.e., If A is possible, and if B follows from the assumption of A, then B is is possible) in the context of a dialectical debate where it has been asserted that a given proposition is possible, even it is neither true now nor it will ever be, and where at the same time the irrevocability of the past has been endorsed. This suggests to study the MA debate in a setting based on Marion’s (2020) reconstruction of Aristotle’s Dialectical Bouts, adapted to propositions affected by modalities. The setting of Dialectical Bouts for the MA proposed includes•Propositions affected by Reichenbach’s (1948, § 5) three-folded temporal reference, namely: the point of speech S, the point of reference R and the point of the event E. This constitutes our take on Vuillemin’s (1977, 1979, 1984, 1996) suggestion of a “double indexation”.•The dialogical meaning explanation for modalities understood as involving hypotheticals. •The dialogical rules that settle the commitments undertaken when endorsing Aristotle’s Possibility Principle. In fact, in relation to the notion of possibility at work in Vuillemin’s (1996) reconstruction we explored different formulations of the Possibility Rule. Still, there remains a dearth of researches confronting the different formulations of the Possibility Rule with the texts studied by Crubellier (2010) and Rosen and Malink (2012). More generally and coming back to my remarks above, one of the most fruitful insights that can be gained from Vuillemin’s writings on the MA, is that such kind of debates provide an instance of a general pattern for reasoning that I shall call Dialectical Bouts of Material Admissibility (BMA). The rationale behind such kind of argumentation-pattern is to examine the incorporation of new (epistemological, ontological or logical) principles against the background of the commitments undertaken by endorsing a specific set of assertions and meaning explanations. They display the kind of abductive procedure stressed by Crubellier’s (2014) study of syllogism. Under this perspective Ebbinghaus’s (1964) casting of the inferential moves that reduce imperfect syllogisms to perfect ones as implementing an admissibility procedure, represents a logical generalization of the material procedures at stake in the Dialectical Bouts of Material Admissibility. Furthermore if, as stressed by Duthil-Novaes (2005) Medieval Obligations represent a development of Aristotelian Bouts aimed at the ludic exercise of consistency maintenance, DMA should be rather linked to the Islamic tradition of dialectical theory [jadal, munāẓara, ādāb al-baḥth], aimed at the epistemological task of what Young (2017) calls the forging of principles, including legal and deontic ones. In a more contemporary setting, DMA can be related to Brandom’s (2000, pp. 66-77) considerations on Non-Conservative Extensions, where the point of dialectical procedures is put under public Socratic scrutiny the discovery and elucidation of concepts. This general point on Dialectical Bouts of Material Admissibility can be seen as underlying Vuillemin’s project of linking the study of the MA with the classification of philosophical systems.The present paper does not contain a fully developed study on such Dialectical Bouts, but it is rather is an invitation to pick up the gauntlet that Jules Vuillemin threw into the ring.
