Book Description
This volume provides a unique primary source on the history and philosophy of mathematics and the exact sciences in the mediaeval Arab world. The second of five comprehensive volumes, this book offers a detailed exploration of Arabic mathematics in the eleventh century as embodied in the legacy of the celebrated polymath al-Hasan ibn al-Haytham. Extensive analyses and annotations from the eminent scholar, Roshdi Rashed, support a number of key Arabic texts from Ibn al-Haytham’s treatises in infinitesimal mathematics, translated here into English for the first time. Rashed shows how Ibn al-Haytham’s works demonstrate a remarkable mathematical competence in mathematical subjects like the quadrature of the circle and of lunes, the calculation of the volumes of paraboloids, the problem of isoperimetric plane figures and solid figures with equal surface areas, along with the extraction of square and cubic roots. The present text is complemented by the first volume of A History of Arabic Sciences and Mathematics, which focused on founding figures and commentators in the ninth and tenth centuries Archimedean-Apollonian mathematical ‘School of Baghdad’. This constellation of works illustrates the historical and epistemological development of ‘infinitesimal mathematics’ as it became clearly articulated in the oeuvre of Ibn al-Haytham. Contributing to a more informed and balanced understanding of the internal currents of the history of mathematics and the exact sciences in Islam, and of its adaptive interpretation and assimilation in the European context, this fundamental text will appeal to historians of ideas, epistemologists and mathematicians at the most advanced levels of research.

Classical Mathematics from Al-Khwarizmi to Descartes
Author: Roshdi Rashed
Publisher: Routledge
ISBN: 1317622391
Category : History
Languages : en
Pages : 768
Book Description
This book follows the development of classical mathematics and the relation between work done in the Arab and Islamic worlds and that undertaken by the likes of Descartes and Fermat. ‘Early modern,’ mathematics is a term widely used to refer to the mathematics which developed in the West during the sixteenth and seventeenth century. For many historians and philosophers this is the watershed which marks a radical departure from ‘classical mathematics,’ to more modern mathematics; heralding the arrival of algebra, geometrical algebra, and the mathematics of the continuous. In this book, Roshdi Rashed demonstrates that ‘early modern,’ mathematics is actually far more composite than previously assumed, with each branch having different traceable origins which span the millennium. Going back to the beginning of these parts, the aim of this book is to identify the concepts and practices of key figures in their development, thereby presenting a fuller reality of these mathematics. This book will be of interest to students and scholars specialising in Islamic science and mathematics, as well as to those with an interest in the more general history of science and mathematics and the transmission of ideas and culture.

Ibn al-Haytham's Theory of Conics, Geometrical Constructions and Practical Geometry
Author: Roshdi Rashed
Publisher: Routledge
ISBN: 1135072531
Category : History
Languages : en
Pages : 770
Book Description
Theory of Conics, Geometrical Constructions and Practical Geometry: A History of Arabic Sciences and Mathematics Volume 3, provides a unique primary source on the history and philosophy of mathematics and science from the mediaeval Arab world. The present text is complemented by two preceding volumes of A History of Arabic Sciences and Mathematics, which focused on founding figures and commentators in the ninth and tenth centuries, and the historical and epistemological development of ‘infinitesimal mathematics’ as it became clearly articulated in the oeuvre of Ibn al-Haytham. This volume examines the increasing tendency, after the ninth century, to explain mathematical problems inherited from Greek times using the theory of conics. Roshdi Rashed argues that Ibn al-Haytham completes the transformation of this ‘area of activity,’ into a part of geometry concerned with geometrical constructions, dealing not only with the metrical properties of conic sections but with ways of drawing them and properties of their position and shape. Including extensive commentary from one of world’s foremost authorities on the subject, this book contributes a more informed and balanced understanding of the internal currents of the history of mathematics and the exact sciences in Islam, and of its adaptive interpretation and assimilation in the European context. This fundamental text will appeal to historians of ideas, epistemologists and mathematicians at the most advanced levels of research.

The Philosophers and Mathematics
Author: Hassan Tahiri
Publisher: Springer
ISBN: 3319937332
Category : Mathematics
Languages : en
Pages : 357
Book Description
This book explores the unique relationship between two different approaches to understand the nature of knowledge, reality, and existence. It collects essays that examine the distinctive historical relationship between mathematics and philosophy. Readers learn what key philosophers throughout the ages thought about mathematics. This includes both thinkers who recognized the relevance of mathematics to their own work as well as those who chose to completely ignore its many achievements. The essays offer insight into the role that mathematics played in the formation of each included philosopher’s doctrine as well as the impact its remarkable expansion had on the philosophical systems each erected. Conversely, the authors also highlight the ways that philosophy contributed to the growth and transformation of mathematics. Throughout, significant historical examples help to illustrate these points in a vivid way. Mathematics has often been a favored interlocutor of philosophers and a major source of inspiration. This book is the outcome of an international conference held in honor of Roshdi Rashed, a renowned historian of mathematics. It provides researchers, students, and interested readers with remarkable insights into the history of an important relationship throughout the ages.

Founding Figures and Commentators in Arabic Mathematics
Author: Roshdi Rashed
Publisher: Routledge
ISBN: 1136620001
Category : History
Languages : en
Pages : 814
Book Description
In this unique insight into the history and philosophy of mathematics and science in the mediaeval Arab world, the eminent scholar Roshdi Rashed illuminates the various historical, textual and epistemic threads that underpinned the history of Arabic mathematical and scientific knowledge up to the seventeenth century. The first of five wide-ranging and comprehensive volumes, this book provides a detailed exploration of Arabic mathematics and sciences in the ninth and tenth centuries. Extensive and detailed analyses and annotations support a number of key Arabic texts, which are translated here into English for the first time. In this volume Rashed focuses on the traditions of celebrated polymaths from the ninth and tenth centuries ‘School of Baghdad’ - such as the Banū Mūsā, Thābit ibn Qurra, Ibrāhīm ibn Sinān, Abū Ja ́far al-Khāzin, Abū Sahl Wayjan ibn Rustām al-Qūhī - and eleventh-century Andalusian mathematicians like Abū al-Qāsim ibn al-Samh, and al-Mu’taman ibn Hūd. The Archimedean-Apollonian traditions of these polymaths are thematically explored to illustrate the historical and epistemological development of ‘infinitesimal mathematics’ as it became more clearly articulated in the eleventh-century influential legacy of al-Hasan ibn al-Haytham (‘Alhazen’). Contributing to a more informed and balanced understanding of the internal currents of the history of mathematics and the exact sciences in Islam, and of its adaptive interpretation and assimilation in the European context, this fundamental text will appeal to historians of ideas, epistemologists, mathematicians at the most advanced levels of research.

The Poetics of Ancient and Classical Arabic Literature
Author: Esad Durakovic
Publisher: Routledge
ISBN: 1317520491
Category : Religion
Languages : en
Pages : 296
Book Description
Through analysing ancient and classical Arabic literature, including the Qur'an, from within the Arabic literary tradition, this book provides an original interpretation of poetics, and of other important aspects of Arab culture. Ancient Arabic literature is a realm of poetry; prose literary forms emerged rather late, and even then remained in the shadow of poetic creative efforts. Traditionally, this literature has been viewed through a philologist’s lens and has often been represented as ‘materialistic’ in the sense that its poetry lacked imagination. As a result, Arabic poetry was often evaluated negatively in relation to other poetic traditions. The Poetics of Ancient and Classical Arabic Literature argues that old Arabic literature is remarkably coherent in poetical terms and has its own individuality, and that claims of its materialism arise from a failure to grasp the poetic principles of the Arabic tradition. Analysing the Qur’an, which is known for confronting the poetry of the time, this book reveals that "post Qur’anic" literature came to be defined against it. Thus, the constitution and interpretation of Arabic literature imposed itself as a particular exegesis of the sacred Text. Disputing traditional interpretations by arguing that Arabic literature can only be assessed from within, and not through comparison with other literary traditions, this book is of interest to students and scholars of Islamic Studies, Arabic Studies and Literary Studies.

Ethics in Islam
Author: Nuha Al-Shaar
Publisher: Routledge
ISBN: 1317575849
Category : Philosophy
Languages : en
Pages : 267
Book Description
Offering a new reading of Islamic ethical and political thought in the Būyid period (334-440/946-1048), this book focuses particularly on the philosopher Abū Hayyān al-Tawhīdī who lived in Baghdad and what is now western Iran. Ethics in Islam provides the first major treatment of al-Tawhīdī's ethics, political thought, and social idealism, investigating the complex influences that shaped this thought and especially his concept of friendship, which is analysed in the unique context of Būyid society. Al-Tawhīdī revives the value of friendship in politics. He introduces it as the best way to reform social and political order and as a means to the good life, to restrain passion and self-interest, to bring about cooperation and promote reason, and for action in opposition to religious zeal. Instead of seeing him as alienated from society, supposedly rejecting traditional Muslim beliefs, this book places him in his historical and intellectual contexts, and shows that while he was original in many ways, his outlook was firmly rooted in the Islamic culture in which he was educated. Contributing to modern discussions of Islam and political ethics, this book is of interest to scholars and researchers of political philosophy, comparative ethical thought and Islamic studies.

Eastern Rome and the Rise of Islam
Author: Olof Heilo
Publisher: Routledge
ISBN: 1317326636
Category : History
Languages : en
Pages : 163
Book Description
The emergence of Islam in the seventh century AD still polarises scholars who seek to separate religious truth from the historical reality with which it is associated. However, history and prophecy are not solely defined by positive evidence or apocalyptic truth, but by human subjects, who consider them to convey distinct messages and in turn make these messages meaningful to others. These messages are mutually interdependent, and analysed together provide new insights into history. It is by way of this concept that Olof Heilo presents the decline of the Eastern Roman Empire as a key to understanding the rise of Islam; two historical processes often perceived as distinct from one another. Eastern Rome and the Rise of Islam highlights significant convergences between Early Islam and the Late Ancient world. It suggests that Islam’s rise is a feature of a common process during which tensions between imperial ambitions and apocalyptic beliefs in Europe and the Middle East cut straight across today’s theological and political definitions. The conquests of Islam, the emergence of the caliphate, and the transformation of the Roman and Christian world are approached from both prophetic anticipations in the Ancient and Late Ancient world, and from the Medieval and Modern receptions of history. In the shadow of their narratives it becomes possible to trace the outline of a shared history of Christianity and Islam. The "Dark Ages" thus emerge not merely as a tale of sound and fury, but as an era of openness, diversity and unexpected possibilities. Approaching the rise of Islam as a historical phenomenon, this book opens new perspectives in the study of early religion and philosophy, as well as providing a valuable resource for students and scholars of Islamic Studies.
