COMPUTERS AS CARTOGRAPHIC TOOLS

Abstract

In their exploration of an alternative approach to large historical databases, the authors aim to bridge the gap between the anticipations regarding Web-based collaborative work and the prevailing practices and academic culture in social and economic history. Until now, the collaboratory model has been derived from examples in the natural sciences. Moreover, publications on collaboratories in the social sciences and humanities revolved primarily around the potential of this model and were rarely based on actual research practices. In this article, the authors report on practices, risks, and opportunities of collaboratories in the field of social and economic history. The collaboratory model is a feasible alternative for the creation of large historical databases, but the practical challenges of such an enterprise are greater than generally assumed. In the concluding section, the authors formulate a number of guidelines for scholars interested in setting up collaboratories.     

MIRACLES, HISTORICAL TESTIMONIES, AND PROBABILITIES

The topic and methods of David Hume's “Of Miracles” resemble his historiographical more than his philosophical works. Unfortunately, Hume and his critics and apologists have shared the pre‐scientific, indeed a historical, limitations of Hume's original historical investigations. I demonstrate the advantages of the critical methodological approach to testimonies, developed initially by German biblical critics in the late eighteenth century, to a priori discussions of miracles. Any future discussion of miracles and Hume must use the critical method to improve the quality and relevance of the debate. Hume's definition of miracles as breaking the laws of nature is anachronistic. The concept of immutable laws of nature was introduced only in the seventeenth century, thousands of years after the Hebrews had introduced the concept of miracles. Holder and Earman distinguish the posterior probability of the occurrence of a particular miracle from that of the occurrence of some miracle. I argue that though this distinction is significant, their formulae for evaluating the respective probabilities are not useful. Even if miracle hypotheses have low probabilities, it may still be rational to accept and use them if there is no better explanation for the evidence of miracles. Biblical critics and historians do not examine the probabilities of miracle hypotheses, or any other hypotheses about the past, in isolation, but in comparison with competing hypotheses that attempt to better explain, increase the likelihood of a broader scope of evidence, as well as be more fruitful. The fruitful and simple theories of Hume's later and better contemporaries, the founders of biblical criticism, offer the best explanation of the broadest scope of evidence of miracles. Moreover, they do so by being linguistically sensitive to the ways “miracle” was actually used by those who claimed to have observed them. The lessons of this analysis for historians and philosophers of history—that the acceptance of historical hypotheses is a comparative endeavor, and that the claims of those in the past must be assessed in their own terms—ought to be clear.     

HISTORICAL UNDERSTANDING AND HISTORICAL INTERPRETATION AS CONTEXTUALIZATION

This article discusses the theoretical problems pertaining to the relationship between historical contextualization and historical understanding and interpretation. On the one hand, there is the view that documents need to be understood in relation to their historical context; on the other, it is not clear how a historian can get out of his or her own historical context in order to be able to engage with the conceptual frameworks, beliefs, or ways of reasoning that are radically different from his or her own. The paper proposes a resolution to this dilemma; its upshot is that historical understanding is constituted by contextualization.     

KOSELLECK,ARENDT, AND THE ANTHROPOLOGY OF HISTORICAL EXPERIENCE

This essay is the first attempt to compare Reinhart Koselleck's Historik with Hannah Arendt's political anthropology and her critique of the modern concept of history. Koselleck is well‐known for his work on conceptual history as well as for his theory of historical time(s). It is my contention that these different projects are bound together by Koselleck's Historik, that is, his theory of possible histories. This can be shown through an examination of his writings from Critique and Crisis to his final essays on historical anthropology, most of which have not yet been translated into English. Conversely, Arendt's political theory has in recent years been the subject of numerous interpretations that do not take into account her views about history. By comparing the anthropological categories found in Koselleck's Historik with Arendt's political anthropology, I identify similar intellectual lineages in them (Heidegger, Löwith, Schmitt) as well as shared political sentiments, in particular the anti‐totalitarian impulse of the postwar era. More importantly, Koselleck's theory of the preconditions of possible histories and Arendt's theory of the preconditions of the political, I argue, transcend these lineages and sentiments by providing essential categories for the analysis of historical experience.     

OPACITY AND TRANSPARENCY IN HISTORICAL REPRESENTATIONS

In his latest book Frank Ankersmit develops a comprehensive philosophical perspective on the problem of the truth and reference of historical representations. The approach and the wider perspective of the book largely belong to what could be called the postmodernist paradigm, in spite of some recent attempts to interpret Ankersmit's recent work differently. Since his 1983 Narrative Logic Ankersmit has propounded the view that individual statements that constitute historical representations may have reference, but that representations themselves do not. His most recent book remains faithful to this position and elaborates it further. This essay examines Ankersmit's arguments as well as the assumptions and implications of this view.

HARTOG,KOSELLECK, AND RICOEUR: HISTORICAL ANTHROPOLOGY AND THE CRISIS OF THE PRESENT

I enquire here into whether historical anthropology may serve to orient the critique of modes of temporalization under the conditions specific to what François Hartog designates as the contemporary regime of historicity. To this end, I bring Hartog into conversation with Paul Ricoeur: both arrive at a diagnosis of the crisis of the present on the basis of a parallel interiorization of the metahistorical categories of Reinhart Koselleck. Sharing a common interlocutor, the diagnoses at which they arrive are nevertheless quite different in nature, a result of the way in which these categories are inflected alternatively toward the anthropological perspective of fundamental temporalization and the semantic perspective of articulation at the level of “orders of time.” I suggest that the crisis of the present eludes the grasp of both and, with a view to gaining a more secure critical purchase over this crisis, propose a framework for bringing them into conversation.     

THE ENDURING PUBLIC STRUGGLE TO CONSTRUCT,CONTROL, AND CHALLENGE HISTORICAL MEMORIES

Sumit Guha's History and Collective Memory in South Asia, 1200–2000 develops important arguments about the public significance of historical knowledge and the essential role of historians in public life. All societies need collective memories to sustain their cultural identities, as Guha shows in this wide‐ranging account of how such memories have been constructed in South Asian societies since the thirteenth century. The knowledge of historical experts is increasingly challenged or derided by contemporary social groups and political activists, who circulate their own historical narratives via new networks of communication. Political uses of historical knowledge are not new, however, as Guha shows in detailed accounts of how Hindu, Muslim, and British imperial regimes all used historical narratives to justify their own power. He also explains how other social groups challenged official historical narratives with their own popular stories about the past. This book contributes to recent work in global intellectual history by comparing similarities in the historical practices of premodern Europe and South Asia, discussing the cross‐cultural exchanges in colonial‐era institutions, and describing postcolonial challenges to European ideas. Guha thus offers an insightful analysis of how social and political forces influence and respond to the cloistered institutions that produce historical knowledge and construct collective memories. He concludes that evidence‐based historical narratives must be continually defended amid current public assaults on historical knowledge in both South Asia and the United States. More generally, Guha's book suggests the need for ongoing analysis of how public events, social conflicts, and new communication systems can reshape or discredit the work of historical experts.     

1. AT HOME AND IN THE WORKPLACE: A HISTORICAL INTRODUCTION TO THE “SPATIAL TURN”

This introduction places the forum contributions in the wider context of the “spatial turn” within the humanities and social sciences. Following a survey of the historical trajectories of the field, a review of impulses from different disciplines, and a sketch of general developments over the last few decades, the editors exemplify key approaches, methods, and conceptual advances with reference to gender studies. The focus then turns to the structure, main themes, and specific contents of this collection, which features both case studies and theoretical reflections. In conclusion, the essay underlines the significance and further potential of the “spatial turn.”     

A MICROMECHANICAL INELASTIC MODEL FOR HISTORICAL MASONRY

A micromechanical damage model for the Snite element modelling of historical masonry structures is presented in this article. Masonry is considered as a composite medium made up of a periodic assembly of blocks connected by orthogonal bed and head mortar joints. The constitutive equations, in plane stress, are based on the homogenisation theory and they consider the non linear stress-strain relationship in terms of mean stress and mean strain. Different in-plane damage mechanisms, involving both mortar and blocks, are considered and the damage process is governed by evolution laws based on an energetic approach derived from Fracture Mechanics and on a non-associated Coulomb friction law. The failure domain of the model is analysed both in the equivalent stress and in the principal stress space considering different orientations of the bed joints relative to the loading direction. A comparison with experimental results is provided. A numerical simulation of masonry walls subjected to horizontal forces proportional to their own weight is shown in order to discuss the model's capability of describing the influence of the masonry microstructure on its mechanical behaviour.     

TRUTH AND MEANING IN HISTORICAL INTERPRETATION: A DAVIDSONIAN APPROACH

This essay argues that Donald Davidson's work in philosophy sheds light on debates about truth, meaning, and context in historical interpretation. Drawing on distinctions between Davidson's project and that of his mentor, W. V. O. Quine, I aim to show that certain ambiguities that have arisen in the methodological reflections of Quentin Skinner and Frank Ankersmit, to take representatives of contrastive approaches to intellectual history, are clarified once we reckon with Davidson's ideas. This discussion leads to a case for the broader pertinence of Davidson's work to historical writing, which insists that his focus on the centrality of truth to disagreement bears salutary consequences for thinking about what constitutes compelling historical scholarship.     

THE POETICS OF ANCIENT GREEK MEMORY AND THE HISTORICAL IMPERATIVE

This book examines Greek engagements with the past as articulations of memory formulated against the contingency of chance associated with temporality. Based on a phenomenological understanding of temporality, it identifies four memorializing strategies: continuity (tradition), regularity (exemplarity), development, and acceptance of chance. This framework serves in pursuing a twofold aim: to reconstruct the literary field of memory in fifth‐century bce Greece; and to interpret Greek historiography as a memorializing mode. The key contention advanced by this approach is that acts of memory entailed an “idea of history” that was articulated not only in historiography, but also in epinician poetry, elegy, tragedy, and oratory. The book offers a rich account of poetic conventions and contexts through which each of these genres counterbalanced contingency through the use of exemplary and traditional modes of memory. This fine analysis highlights the grip of the present on the past as a significant feature of both historiographical and nonhistoriographical genres. The essay argues that this work fills a disciplinary gap by extending the reflection on memory to a new period, Greek antiquity. The retrospective positioning of this period at the outset of Western historical thought brings Grethlein's investigation to the center of debates about memory, temporality, and the meaning history. In engaging with the book's argument, the essay suggests that historiographical memory emerged in Greece not as a first‐order encounter with time, but as a second‐order encounter with forgetting. This confrontation marked a certain separation of historiography from other memorializing genres. Whereas poetic and rhetorical memories were posited against contingency, historiography sought to retrieve those aspects of the past that may otherwise have been irretrievably lost and forgotten. In doing so, it formulated the historiographical imperative as a negation of forgetting that problematized the truth‐value of memory and the very act of remembering the past.
