In the early years of Mendelism, 1900-1910, William Bateson established a productive research group consisting of women and men studying biology at Cambridge. The empirical evidence they provided through investigating the patterns of hereditary in many different species helped confirm the validity of the Mendelian laws of heredity. What has not previously been well recognized is that owing to the lack of sufficient institutional support, the group primarily relied on domestic resources to carry out their work. Members of the group (...) formed a kind of extended family unit, centered on the Batesons' home in Grantchester and the grounds of Newnham College. This case illustrates the continuing role that domestic environments played in supporting scientific research in the early 20th century. (shrink)

The marriage of Sally Peris Hughes (1895–1984) and Franz Schrader (1891–1962) in November 1920 launched a highly successful scientific collaboration that lasted over four decades. The Schraders were avid naturalists, adroit experimentalists, and keen theoreticians, and both had long, productive, and fruitful careers in zoology. They offer an extraordinarily rich case study that provides an insightful view of the work carried out in several areas of the life sciences from the 1920s to the 1960s—fieldwork, cytology, cytogenetics, and entomology—as well as (...) critical aspects of the social world of contemporary science. By focusing on the fieldwork the couple carried out in Mexico and Central America in the late 1920s and early 1930s, this paper seeks to illuminate how this collaborative scientific marriage embodies a collective, complex, and integrated personal and social arrangement that served to enhance both knowledge production and disciplinary development in several areas of science. It also reveals ways in which marriage could serve as a means to help both parties navigate and negotiate restrictive sociocultural norms and institutional arrangements in science involving gender, power, and authority in the early twentieth century.

With historical hindsight, it can be little questioned that the view of protozoa as unicellular organisms was important for the development of the discipline of protozoology. In the early years of this century, the assumption of unicellularity provided a sound justification for the study of protists: it linked them to the metazoa and supported the claim that the study of these “simple” unicellular organisms could shed light on the organization of the metazoan cell. This prospect was significant, given the state (...) of cytology circa 1910. In the wake of the major gains made in understanding nuclear division in the last two decades of the nineteenth century, cytology was suddenly confronted with many, seemingly less penetrable, problems. Several aspects of nuclear organization still remained unexplained, and recent research had revealed the presence in the cytoplasm of structures whose functions in cell life were unknown. Classical methods of cytology, relying on descriptive, morphological analysis, seemed ill equipped to resolve these questions.Hertwig's program for protozoology, grounded in the assumption of the fundamental unity of organization in protozoa and metazoa, offered a potential means for investigating these and other problems of cell theory. Linked to mainstream cytology, protozoology was advocated as a means of experimentally investigating key biolobical processes — reproduction, metabolism, and organelle morphology and physiology — less accessible in higher organisms. Protozoa were hailed as prime experimental organisms, in which cell structure and function could be more easily studied. Unlike the metazoan cell, they could be subjected to controlled experiments in which the external environment was modified and the effects monitored. Protozoa offered, in other words, a promising experimental means by which to investigate the cell — its structures and its processes.The success of this program within Germany was soon apparent. In contrast to the rather neglected state of the discipline in 1900, protozoology began to be recognized as more than a somewhat obscure area of study for specialists. In practical terms, this translated into greater numbers of students attracted to the field, increased institutional support for the discipline, and its elevation in status within the biological sciences as new developments, particularly in connection with medical applications, began to draw attention to the field.64The unicellular hypothesis also promoted the internal development of the science. It provided a rationale for introducing the various techniques used in cytology, embryology, physiology, and the new field of biochemistry as suitable research tools for protozoology as well. This vastly extended the research possibilities and facilitated the understanding of, among other things, protozoan organization, modes of reproduction, and evolutionary relationships. The new experimental grounding of the discipline in turn fitted in well with developments in biology at large: in contrast to the descriptive methodology that had predominated in the nineteenth century, this new experimental program placed protozoology at the forefront of the early twentieth-century movement to make biology an experimental science comparable to physics and chemistry.Yet the criticism of the unicellular hypothesis can also be seen as having served a valuable function within the development of the discipline. It focused attention on the study of protists as organisms in their own right, not simply as models for metazoan cells. More generally, it helped to remind biologists of the particular evolutionary assumptions that supported this conception. Dobell and other British critics pointed out, among other things, the association between the theory of recapitulation and the interpretation of protozoa as unicellular organisms. At the time when the recapitulation theory and the germ-layer doctrine were in decline, it was important to stress how these evolutionary ideas also entered into the contemporary concepts of subsidiary specialties. This was as true for protozoology as it was for cell theory itself. The chromidial theory, in its various guises, and the binuclearity hypothesis did in fact contain elements of recapitulationist reasoning, and they were open to criticism for the same kind of overly speculative theorizing that characterized this evolution theory. Dobell's critique forced protozoologists and cell theorists alike to review the theoretical postulates guiding their investigations.In the absence of further historical studies, it is hard to evaluate the consequences of this debate in later years. The issue was not whether protozoa were the precursors of metazoa — both sides accepted this. They disagreed over which particular protozoon had served as the ancestral form, and this, in turn, influenced their stance on the question of unicellularity. The situation is little changed today. Because the former question is still an open one, the latter remains so too. Both of the models for the origin of multicellular organisms — colonies of ciliates versus multinucleate protists — are still presented as possible mechanisms in modern textbooks of evolution. Unable to judge the dispute in terms of the ultimate validity of the competing conceptions, the historian requires other criteria. It perhaps becomes more important to evaluate the issues in the context of the internal and external stimulus they provided the discipline.65 In these terms, and from the present historical vantage point, Hertwig's research program for protozoology, based upon the unicellular hypothesis, appears to have been a successful one.

Muriel Wheldale, a distinguished graduate of Newnham College, Cambridge, was a member of William Bateson's school of genetics at Cambridge University from 1903. Her investigation of flower color inheritance in snapdragons (Antirrhinum), a topic of particular interest to botanists, contributed to establishing Mendelism as a powerful new tool in studying heredity. Her understanding of the genetics of pigment formation led her to do cutting-edge work in biochemistry, culminating in the publication of her landmark work, The Anthocyanin Pigments of Plants (1916). (...) In 1915, she joined Frederick Gowland Hopkin's Department of Biochemistry as assistant and in 1926 became one of the first women to be appointed university lecturer. In 1919 she married the biochemist Huia Onslow, with whom she collaborated until his death in 1922. This paper examines Wheldale's work in genetics and especially focuses on the early linkage of Mendelian methdology with new techniques in biochemistry that eventually led to the founding of biochemical genetics. It highlights significant issues in the early history of women in genetics, including the critical role of mentors, funding opportunities, and career strategies. (shrink)

In 1853, the young Thomas Henry Huxley published a long review of German cell theory in which he roundly criticized the basic tenets of the Schleiden-Schwann model of the cell. Although historians of cytology have dismissed Huxley's criticism as based on an erroneous interpretation of cell physiology, the review is better understood as a contribution to embryology. "The Cell-theory" presents Huxley's "epigenetic" interpretation of histological organization emerging from changes in the protoplasm to replace the "preformationist" cell theory of Schleiden and (...) Schwann (as modified by Albert von Kölliker), which posited the nucleus as the seat of organic vitality. Huxley's views influenced a number of British biologists, who continued to oppose German cell theory well into the twentieth century. Yet Huxley was pivotal in introducing the new German program of "scientific zoology" to Britain in the early 1850s, championing its empiricist methodology as a means to enact broad disciplinary and institutional reforms in British natural history.

The history of science within the Ibero-American context has not received significant attention from historians of science. In the case of historical studies of science in Spain and Latin America, research has primarily been carried out under the umbrella of “centers and peripheries,” indicating that despite their historiographical and epistemological importance, narratives on science within certain national contexts have analytical limitations. Recent research has indicated a need to reconstruct transnational stories that account for how knowledge produced in developing countries forms (...) part of the circulation of international knowledge via international networks of collaboration.

This article offers an overview of the various formulations of "jihad" during the first six Islamic centuries (7th-13th CE), showing them to be embedded in particular socio-historical contexts. If the essential significance of "jihad" as righteous cause (i.e., action for the sake of a moral order) is shown to have been variously altered according to the needs and conditions of the Muslim community, significant possibilities arise for a contemporary understanding of "jihad" that is relevant to the needs and circumstances of (...) the Muslim community today. Some features of the "jihad" tradition, although specific to a particular period and with little relevance today, continue to inform the current discussion on "jihad." Discussion of the "jihad" tradition, then, should take care to distinguish the historically incidental features of the tradition from those with an enduring relevancy. By doing so, the "jihad" tradition will be able to contribute to discussions on the relation of religion to the public order and political organization, even those not limited to Islam. (shrink)

Sufism - spiritual practice, intellectual discipline, literary tradition, and social institutionhas played an integral role in the moral formation of Muslim society. Its aspiration toward a universal kindness to all creatures beyond the requirements of Islamic law has added a distinctly hypernomian dimension to the moral vision of Islam, as evidenced in a wide range of Sufi literature. The universal perspective of Sufism, fully rooted in Islamic revelation, yields a lived (and not just studied) ethics with the potential to view (...) and embrace all creatures through a single ethical vision, regardless of religious or other affiliation. This side of Islam, both acknowledging and surpassing the outlook of the legal heritage, offers important insight into understanding the nature of Muslim society as both Islamic and metaIslamic in religious orientation. Sufism, still significant in today's Islamic world, thus offers important material for locating Islam as part of an international order with principles and standards that resonate deeply with the moral vision of Islam itself.

Individuals with major depressive disorder (MDD) often ruminate about past experiences, especially those with negative content. These repetitive thoughts may interfere with cognitive processes related to attention and conflict monitoring. However, the temporal nature of these processes as reflected in event-related potentials (ERPs) has not been well-described. We examined behavioral and ERP indices of conflict monitoring during a modified flanker task and the allocation of attention during an attentional blink (AB) task in 33 individuals with MDD and 36 healthy controls, (...) and whether their behavioral performance and ERPs varied with level of rumination. N2 amplitude elicited by the flanker task was significantly reduced in participants with MDD compared to healthy controls. Level of self-reported rumination was also correlated with N2 amplitude. In contrast, P3 amplitude during the AB task was not significantly different between groups, nor was it correlated with rumination. No significant differences were found in behavioral task performance measures between groups or by rumination levels. These findings suggest that rumination in MDD is associated with select deficits in cognitive control, particularly related to conflict monitoring. (shrink)

: Skepticism as doubts about religious knowledge played a significant role in the intellectual reflection of the fourth and fifth Islamic centuries, a period of considerable plurality within Islam on many levels. Such skepticism was directed at revealed knowledge that spelled out the customs and norms particular to the Islamic way of life. Doubts were pushed by theologians who, themselves caught within a web of "parity of evidence" between the various schools of Islam, saw little hope of verifying the superiority (...) of Muslim ways over those of other communities, and Muslim intellectuals who viewed the particular religio-moral practices of Islam as shamefully atavistic and primitive, seeking instead to table "visible" religion for an esoterically conceived one. Against such detractors, a significant scholar of the period, Abū l-Hasan al-'Āmirī, constructed a philosophical defense of exoteric Islam, arguing in Aristotelian terms for the superiority of religio-moral knowledge over philosophical knowledge in light of the greater benefit of the former to the welfare of society and the superiority of Islamic religio-moral knowledge, since, he claims, it squares with logic more than any other communal way of life. The argument, one of many seeking to come to terms with the intellectual vagaries of the day, demonstrates how skepticism pushed scholars to explore more profoundly the nature of religion. In al-'Āmirī's case, his argument, metaphysically based with mystical inclinations, set the stage for later articulations of Islamic religiosity that integrated the human mind into the arena of Islam's revealed way of life.

The first major treatment of skepticism in Islam, this book explores the critical role of skeptical thinking in the development of theology in Islam. It examines the way key thinkers in classical Islam faced perplexing questions about the nature of God and his relation to the world, all the while walking a fine line between belief in God's message as revealed in the Qur'an, and the power of the mind to discover truths on its own. Skepticism in Classical Islam reveals (...) how doubt was actually an integral part of scholarly life at this time. Skepticism is by no means synonymous with atheism. It is, rather, the admission that one cannot convincingly demonstrate a truth claim with certainty, and Islam's scholars, like their counterparts elsewhere, acknowledged such impasses, only to be inspired to find new ways to resolve the conundrums they faced. Whilst their conundrums were unique, their admission of the limits of knowledge shares much with other scholarly traditions. Seeking to put Islam on the map of the broader study of the history of scepticism, this book will be of interest to scholars and students of Religion, History and Philosophy. (shrink)

In this pioneering book, noted international scholars explore the limits and definitions of knowing, thinking, and communicating meaning as we move into the 21st century. Coming from disciplines as diverse as anthropology, philosophy, literature, aesthetics, and art practice, together they work towards reconceiving the boundaries between entrenched domains of knowledge to great effect.

According to the classical Muslim scholar Māwardī, rule is to bring about just order in society in accordance with God’s intentions. The state thus has a role in bringing about divine purposes, and yet Māwardī recognizes the flawed condition of humanity, the ruler included, making it vital that rule be based not solely on the divinely endowed agency of the ruler but more precisely on a set of rules meant to purge the soul of disordered inclinations. In that sense, there (...) are grounds for drawing comparisons between Māwardī and Augustine. (shrink)
