The two sermons edited and translated here for the first time are primary material from the years before the establishment of the Fatimid caliphate in 297/909. The authors have been identified as Abu 'Abd Allah al-Shi'i and Abu'l-'Abbas Muhammad, two brothers who were central to the success of the Ismaili da'wa in North Africa. Da'wa, a term used to describe how Muslims teach others about the beliefs and practices of their Islamic faith, therefore provide a unique view of the nature (...) and development of Islam throughout history. In this case, the primary texts shed light on the development of Islam among the Berbers of the Maghreb. The first text by Abu 'Abd Allah al-Shi'i shows how the arguments for belief in the 'imamate' of the family of the Prophet, that is, the Shi'a belief that all imams should be spiritual descendants of the Prophet Muhammad and his household, were developed and presented to bring new adherents to the cause. The Book of the Keys to Grace by his elder brother Abu'l-'Abbas, too, concerns not only the centrality of the imam in the faith but also sheds light on the hierarchy of the da'wa in this early period and its organisational sophistication. Both texts also reveal the contemporary theology propagated by the Ismaili da'wa, including for instance, the powerful analogy of Moses/Aaron and Muhammad/'Ali, the awareness of a variety of religious traditions and the use of detailed Qur'anic quotations and a wide range of hadith. As such they constitute primary source material of interest not only for Ismaili history but for this early period of Islam in general.". (shrink)

The Ismailis, among whom are the followers of the Aga Khan, rose to prominence during the fourth Islamic/tenth Christian century. They developed a remarkably successful intellectual programme to sustain and support their political activities, promoting demands of Islamic doctrine together with the then newly imported sciences from abroad. The high watermark of this intellectual movement is best illustrated in the writings of the Ismaili theoretician Abu Ya´qub al-Sijistani. Using both published and manuscript writings of al-Sijistani that have hitherto been largely (...) hidden, forgotten or ignored, Dr Paul Walker reveals the scholar's major contribution to the development of philosophical Shiism. He analyses his role in the Ismaili mission of that time and critically assesses the major themes in his combination of philosophy and religious doctrine. (shrink)

The first book-length study of a leading tenth-century Ismaili theoretician Abu Ya'qub al-Sijistani.

This book moves away from the frameworks that have traditionally guided ethical decision-making in the Western clinical setting, towards an inclusive, non-coercive and, reflective dialogic approach to moral decision-making. Inspired in part by Jürgen Habermas's discourse theory of morality and principles of communicative action, the book offers a proportionist approach as a way of balancing out the wisdom in traditional frameworks, set in the actual reality of the clinical situation at hand. Putting this approach into practice requires having a conversation, (...) a dialogue or a discourse, with collaboration amongst all the stakeholders. The aim of the dialogue is to reach consensus in the decision, via mutual understanding of the values held by the patient and others whom they see as significant. This book aims to underscore the moral philosophical foundations for having a meaningful conversation. Life and Death Decision in the Clinical Setting is especially relevant in our contemporary era, characterised medically by an ever-increasing armamentarium of life-sustaining technology, but also by increasing multiculturalism, a multiplicity of faiths, and increasing value pluralism.

The Ikhwan al-Safa (Brethren of Purity), the anonymous adepts of a tenth-century esoteric fraternity based in Basra and Baghdad, hold an eminent position in the history of science and philosophy in Islam due to the wide reception and assimilation of their monumental encyclopaedia, the Rasa'il Ikhwan al-Safa (Epistles of the Brethren of Purity). This compendium contains fifty-two epistles offering synoptic accounts of the classical sciences and philosophies of the age; divided into four classificatory parts, it treats themes in mathematics, logic, (...) natural philosophy, psychology, metaphysics, and theology, in addition to didactic fables. Epistles 32 to 36 comprise the first five treatises in the third division of the Rasa'il, on the sciences of the soul and intellect. Combining Islamic revelation with Hellenistic philosophy, the Ikhwan delineate herein their metaphysical system. Epistles 32 and 33 present adaptations of the Pythagorean doctrines, and of Neo-Platonist leitmotifs, whereby a numerical analogy is applied to the unique and transcendent God, or the One, from whom all existence emanates. Epistle 34 takes up the pervasive theme of the correspondence between microcosm and macrocosm, situating the human being as the central link between the celestial and terrestrial realms. In Epistle 35, we find an explanation of the intellectual faculties of the individual human soul, whose ultimate aim is ascension to the timeless reality of pure intellect. Finally, Epistle 36 presents itself as the astrological epistle par excellence of the Rasa'il; from the coming-to-be of worms, to the emergence of religions and empires, nothing in the sub-lunar sphere escapes the determining influence of the celestial cycles.

The theory of the firm did not exist, in any serious manner, until around 1970. Only then did the current theory of the firm literature begin to emerge, based largely upon the work of Ronald Coase and to a lesser degree Frank Knight. It was work by Armen Alchian, Robert Crawford, Harold Demsetz, Michael Jensen, Benjamin Klein, William Meckling and Oliver Williamson, among others, that drove the upswing in interest in the firm among mainstream economists. This accessible book provides a (...) valuable overview of the prehistory of the firm. Spanning an impressive timeline, it delves into Antiquity, the Medieval era, the pre-classical economics period and the 19th and 20th centuries. Next, the book traces the theoretical contributions from pre-classical, classical and neoclassical economics. It will be illuminating reading for students and researchers of the history of economic thought, industrial organization, microeconomic theory and business history. (shrink)

The Greeks invented the words “city,” “democracy,” “people,” “oligarchy,” “liberty,” “citizen.” It is therefore tempting to suppose that they invented the eternal truth of politics, or of our politics, with only one exception: slavery is the major difference between their democracy and democracy as such. For there must exist an eternal politics about which it is possible to philosophize instead of simply writing history. Therein, across the ages, could be found the central essence of politics; despite their diversity, political regimes (...) would have a functional analogy to one another which could be represented in a variety of ways: establishing justice, making men live in peace with one another, defending the group, exercising a domination of the master class over the forces of production.

Extends the ideas of social constructivism to the philosophy of mathematics, developing a powerful critique of traditional absolutist conceptions of mathematics, and proposing a reconceptualization of the philosophy of mathematics.

Although many agree that all teaching rests on a theory of knowledge, this is an in-depth exploration of the philosophy of mathematics for education, building on the work of Lakatos and Wittgenstein.

The exact sectarian affiliation of Shahrastānī has long been a matter of serious debate. Was he possibly an adherent of the Ismaili cause? Considerable recent scholarship purports to establish a connection. The evidence consists of some off-handed remarks by his own contemporaries; what he himself has to say about the Ismailis in his Kitāb al-Milal wa-l-niḥal; and finally, a set of doctrines or analytical categories he uses in his later writings that were later adopted by Nizari Ismailis. However, an impartial (...) look at the evidence does not support the claim that Shahrastānī was himself in any significant way an Ismaili. (shrink)

Kitcher and Aspray distinguish a mainstream tradition in the philosophy of mathematics concerned with foundationalist epistemology, and a ‘maverick’ or naturalistic tradition, originating with Lakatos. My claim is that if the consequences of Lakatos's contribution are fully worked out, no less than a radical reconceptualization of the philosophy of mathematics is necessitated, including history, methodology and a fallibilist epistemology as central to the field. In the paper an interpretation of Lakatos's philosophy of mathematics is offered, followed by some critical discussion, (...) and an extension to a social constructivist position (which might well have been unacceptable to Lakatos).

A traditional problem of ethics in mathematics is the denial of social responsibility. Pure mathematics is viewed as neutral and value free, and therefore free of ethical responsibility. Applications of mathematics are seen as employing a neutral set of tools which, of themselves, are free from social responsibility. However, mathematicians are convinced they know what constitutes good mathematics. Furthermore many pure mathematicians are committed to purism, the ideology that values purity above applications in mathematics, and some historical reasons for this (...) are discussed. MacIntyre’s virtue ethics accommodates both the good mathematician and the ethics of the social practice of mathematics. It demonstrates that purism is compatible with acknowledging the social responsibility of mathematics. Four aspects of this responsibility are mentioned, two concerning the impact of mathematics via education, and two concerning explicit and implicit applications of mathematics. The last of these opens up the performativity of mathematical and measurement applications in society, which change the very processes they are supposed to measure. Although these applications are not explored in detail, they illustrate the importance of considering the ethics and social responsibility of mathematics in society. MacIntyre’s virtue theory opens a broad approach to the controversial topic of the ethics of mathematics encompassing purism, and absolutist and social constructivist philosophies of mathematics, but still enabling ethical critiques of the impact of mathematics on society.

This book offers an up-to-date overview of the research on philosophy of mathematics education, one of the most important and relevant areas of theory. The contributions analyse, question, challenge, and critique the claims of mathematics education practice, policy, theory and research, offering ways forward for new and better solutions. The book poses basic questions, including: What are our aims of teaching and learning mathematics? What is mathematics anyway? How is mathematics related to society in the 21st century? How do students (...) learn mathematics? What have we learnt about mathematics teaching? Applied philosophy can help to answer these and other fundamental questions, and only through an in-depth analysis can the practice of the teaching and learning of mathematics be improved. The book addresses important themes, such as critical mathematics education, the traditional role of mathematics in schools during the current unprecedented political, social, and environmental crises, and the way in which the teaching and learning of mathematics can better serve social justice and make the world a better place for the future.

Moral psychology studies the features of cognition, judgement, perception and emotion that make human beings capable of moral action. Perspectives from feminist and race theory immensely enrich moral psychology. Writers who take these perspectives ask questions about mind, feeling, and action in contexts of social difference and unequal power and opportunity. These essays by a distinguished international cast of philosophers explore moral psychology as it connects to social life, scientific studies, and literature.

The concept of infinity has a long and troubled history. Thus it is a promising concept with which to explore rejection, disagreement, controversy and acceptance in mathematical practice. This paper briefly considers four cases from the history of infinity, drawing on social constructionism as the background social theory. The unit of analysis of social constructionism is conversation. This is the social mechanism whereby new mathematical claims are proposed, scrutinised and critiqued. Minimally, conversation is based on the two roles of proponent (...) and critic. The proponent puts forward a proposal, which is reacted to and evaluated by those in the role of critic. There is a continuum of contexts in which such conversations take place from inner conversations the mathematician has within themselves, and casual face-to face interactions between mathematicians at the chalkboard, all the way to the formal responses of referees and editors to submitted journal papers. Such responses vary from unconditional acceptance, partial acceptance through to outright rejection. There may be disagreements between proponents and critics, among those in the joint role of critic, and broader, community-wide disagreements and controversies, according to specific mathematical proposal and the critical judgements of it.
