‘Procedes Huc’: Voltaire, Newton, and Locke in Lettres Philosophiques

In Lettres philosophiques, Letter XIII is devoted to Locke, as are Letters XIV–XVII to Newton. The ordering of these letters is not adequately explained by comparing the dates of birth or death of the two thinkers. For the Letter on Locke not only precedes but also ‘frames’ those on Newton, in the sense that it provides the reader with a guide through the philosophical intricacies of Letters XIV–XVII. This works in two ways. On the one hand, in order to defend Newton against his detractors Voltaire broadly adopts Locke’s perspective on the relation among words, ideas and things. On the other hand, he subtly and misleadingly grafts Locke’s epistemology onto the Principia, though it differs from Newton’s epistemology in significant respects. For Locke, unlike Newton, holds that we can identify fixed, permanent limits concerning what kind of thing humanity can know of matter and the universe. Voltaire presents Newton’s ideas as though they respected Locke’s limits. However, we can glimpse Voltaire’s own attitude in the final words of Letter XV: ‘Procedes huc, et non ibis amplius’: Voltaire agrees more closely with Locke than Newton concerning the limits of epistemology

Time perception in mild cognitive impairment: interval length and subjective passage of time

Objectives Patients with mild cognitive impairment (MCI) may have difficulties in time perception, which in turn might contribute to some of their symptoms, especially memory deficits. The aim of this study was to evaluate perception of interval length and subjective passage of time in MCI patients as compared to healthy controls. Methods Fifty-five MCI patients and 57 healthy controls underwent an experimental protocol for time perception on interval length, a questionnaire for the subjective passage of time and a neuropsychological evaluation. Results MCI patients presented no changes in the perception of interval length. However, for MCI patients, time seemed to pass more slowly than it did for controls. This experience was significantly correlated with memory deficits but not with performance in executive tests, nor with complaints of depression or anxiety. Conclusions Memory deficits do not affect the perception of interval length, but are associated with alterations in the subjective passage of time

Don't simplify, complexify : from disjunctive to conjunctive theorizing in organization and management studies

In this paper I argue that, rather than theory development aim at simplifying complex organizational phenomena, it should aim at complexifying theories – theoretical complexity is needed to account for organizational complexity. Defining the latter as the capacity for ‘nontrivial’ action, I explore a complex ‘system of picturing’ organizations as objects of study that provides an alternative to the hitherto dominant disjunctive style of thinking. A complex ‘system of picturing’ consists of an open-world ontology, a performative epistemology, and a poetic praxeology. Complex theorizing is conjunctive: it seeks to make connections between diverse elements of human experience through making those analytical distinctions that will enable the joining up of concepts normally used in a compartmentalized manner. Insofar as conjunctive theorizing is driven by the need to preserve the ‘living-forward – understanding backward’ dialectic, it is better suited to grasping the logic of practice and, thus, to doing justice to organizational complexity. We come close to grasping complexity when we restore the past to its own present and make distinctions that overcome dualisms, preserving as much as possible relationality, temporality, situatedness and, interpretive open-endedness. I illustrate the argument with several examples from organizational and management research

Creative processes: From interventions in art to intervallic experiments through Bergson

The recent turn to creativity in geography has led to a proliferation of methodological frameworks that enable us to look at and think about the world differently. For the most part, creativity in geography gets mobilised as an artistic endeavour through empirical research with a particular person or product. One implication of this focus is that creativity gets tied to a foundational subject as the instigator of creative practice. In this paper I want to unpack creativity in geography through a particular theoretical lens, in order to explore a wider array of creative agencies. To this end I turn to Henri Bergson, and his very specific notion of creativity as a process of intuition at the interval. Crucially, Bergson offers a way of processually rethinking the corporeality and materiality of creative practice, enabling us to broaden our engagements with creativity so that they are more open to the diverse ways the material world engages us.<br/

Lavoisier—the Crucial Year: The Background and Origin of His First Experiments on Combustion in 1772

The author explores the origins of the eighteenth-century chemical revolution as it centers on Antoine-Laurent Lavoisier's earliest work on combustion. He shows that the main lines of Lavoisier's theory—including his theory of a heat-fluid, caloric—were elaborated well before his discovery of the role played by oxygen. Contrary to the opinion prevailing at that time, Lavoisier suspected, and demonstrated by experiment, that common air, or some portion of it, combines with substances when they are burned. Professor Guerlac examines critically the theories of other historians of science concerning these first experiments, and tries to unravel the influences which French, German, and British chemists may have had on Lavoisier. He has made use of newly discovered material on this phase of Lavoisier's career, and includes an appendix in which the essential documents are printed together for the first time

Thinking in time: an introduction to Henri Bergson

"In recent years, we have grown accustomed to philosophical language that is intensely self-conscious and rhetorically thick, often tragic in tone. It is enlivening to read Bergson, who exerts so little rhetorical pressure while exacting such a substantial effort of thought. . . . Bergson's texts teach the reader to let go of entrenched intellectual habits and to begin to think differently—to think in time. . . . Too much and too little have been said about Bergson. Too much, because of the various appropriations of his thought. Too little, because the work itself has not been carefully studied in recent decades."—from Thinking in TimeHenri Bergson (1859–1941), whose philosophical works emphasized motion, time, and change, won the Nobel Prize for Literature in 1927. His work remains influential, particularly in the realms of philosophy, cultural studies, and new media studies. In Thinking in Time, Suzanne Guerlac provides readers with the conceptual and contextual tools necessary for informed appreciation of Bergson's work. Guerlac's straightforward philosophical expositions of two Bergson texts, Time and Free Will (1888) and Matter and Memory (1896), focus on the notions of duration and memory—concepts that are central to the philosopher's work. Thinking in Time makes plain that it is well worth learning how to read Bergson effectively: his era and our own share important concerns. Bergson's insistence on the opposition between the automatic and the voluntary and his engagement with the notions of "the living," affect, and embodiment are especially germane to discussions of electronic culture
