Though it did not yet exist as a discrete field of scientific inquiry, biology was at the heart of many of the most important debates in seventeenth-century philosophy. Nowhere is this more apparent than in the work of G. W. Leibniz. This book offers the first in-depth examination of Leibniz's deep and complex engagement with the empirical life sciences of his day, in areas as diverse as medicine, physiology, taxonomy, generation theory, and paleontology. The book shows how these wide-ranging pursuits were not only central to Leibniz's philosophical interests, but often provided the insights that led to some of his best-known philosophical doctrines. Presenting the clearest picture yet of the scope of Leibniz's theoretical interest in the life sciences, the book takes seriously the philosopher's own repeated claims that the world must be understood in fundamentally biological terms. Here it reveals a thinker who was immersed in the sciences of life, and looked to the living world for answers to vexing metaphysical problems. The book casts Leibniz's philosophy in an entirely new light, demonstrating how it radically departed from the prevailing models of mechanical philosophy and had an enduring influence on the history and development of the life sciences. Along the way, the book provides a fascinating glimpse into early modern debates about the nature and origins of organic life, and into how philosophers such as Leibniz engaged with the scientific dilemmas of their era.

This article offers a reading of Jean-Paul Sartre’s phenomenology in light of Jean-Luc Marion’s more recent phenomenology. It may seem odd to compare Sartre to Marion, given that Sartre is well-known for his avowed atheism and his account of intentionality while Marion is primarily known for his work on religious phenomena and counter-intentionality. However, this article shows that there are many ways in which Sartre anticipates Marion’s work on phenomenological reduction and excessive phenomenality. By reading Sartre’s phenomenology in light of Marion’s, and particularly Sartre’s analysis of the viscous slime in Being and Nothingness in relation to Marion’s account of ‘saturated phenomena’, this article presents a fresh interpretation of Sartre as a phenomenologist who has invaluable insights not only on the structures of consciousness and phenomenality, but also for the contemporary theoretical interest in the relationship between human and nonhuman entities.

Abstract Background Recent experimental work has shown that hyper-realistic face masks can pass for real faces during live viewing. However, live viewing embeds the perceptual task (mask detection) in a powerful social context that may influence respondents’ behaviour. To remove this social context, we assessed viewers’ ability to distinguish photos of hyper-realistic masks from photos of real faces in a computerised two-alternative forced choice (2AFC) procedure. Results In experiment 1 (N = 120), we observed an error rate of 33% when viewing time was restricted to 500 ms. In experiment 2 (N = 120), we observed an error rate of 20% when viewing time was unlimited. In both experiments we saw a significant performance cost for other-race comparisons relative to own-race comparisons. Conclusions We conclude that viewers could not reliably distinguish hyper-realistic face masks from real faces in photographic presentations. As well as its theoretical interest, failure to detect synthetic faces has important implications for security and crime prevention, which often rely on facial appearance and personal identity being related.


1. When a straight cylindrical rod is bent into a circle by couples applied at its ends, the resulting state of stress is given, with sufficient accuracy for practical purposes, by the well-known theory of St. Venant. In that theory qunatities of the second and higher orders in therms of strain are neglected, and the resulting solution asserts that the stress is purely longitudinal, so that the rod may be thought of as an assembly of cylindrical fibres, each of which behaves independently of its neighbours. It is evident that this description cannot be exact; for a fibre bent into a circle cannot be kept in tension unless radial forces operate to maintain equilibrium, and in the case considered such forces can come only from actions between adjacent fibres. The apparent paradox is explained by the consideration that those action are of the second order in terms of the curvature, and accordingly are neglected in St. Venant's theory. In connection with a certain problem of elastic instability it was thought desirable to attempt a more accurate description for a particular case, namely, a rod of deep and thin rectangular section. It was found that the equations of equilibrium can be integrated independently of any simplifying assumption, and the stress-distribution determined for curvature of any magnitude. The results have no great practical importance, sice they show that St. Venant's theory gives a close approximation to the facts within that range of strains which actual materials can sustain elastically; but they have some theoretical interest, and accordingly are presented in this paper.

The question about the obliteration of the appendix is of clinical as well as theoretical interest, and it is necessary to find out whether this obliteration is the result of an inflammatory process or physiological involution of the rudimentary organ. In a significant number of the cases described (Trewes-Hartmann), the cause of the obliteration was inflammation of the appendix. The same should be said about the cases of this anomaly that we studied.

Often decay channels that are of theoretical interest cannot be reconstructed exclusively due to missing neutrals (such as neutrinos), or due to single-track vertices. This situation appears both in underground astrophysics experiments as well as in conventional accelerator experiments. A method to “recover” such missing particles from their kinematics and reconstruct “exclusively” the modes would benefit both domains in a number of ways. The main idea is to combine 4-momentum conservations in vertices with available geometric information in the event. The paper gives details of such methods on theBs0→Ds−K+,Ds−→K+K−π−(π0)prototype decay, which also encounters 2-fold ambiguities in its solutions. Such ambiguities can be lifted and the paper shows how, while also addressing the potential the method has in physics analyses and detector studies.

This paper develops the theoretical foundation for computations of spatial displacements from the simple geometric features of points, lines, planes, and their combinations. Using an oriented projective three space with a Clifford Algebra, all these three features are handled in a similar fashion. Furthermore, issues related to uniqueness of computations and minimum number of required features are discussed. It is shown that contrary to the common intuition, specification of a minimum of four points (planes) or three lines are necessary for computation of a unique displacement. Only when the sense of the orientations of these features are specified then the minimum number of required features reduces to three for points and planes and two for lines. The results, in addition to their theoretical interest in computational geometry of motion, have application in robot calibration.

In this paper a model was proposed to calculate the interface potential of a non ideal finite crystal. Most of the research in this issue usually assume ideal conditions to work with infinite perfect crystals. The model includes a perturbative potential to consider an effect associated to finite size crystal and superficial atomic rearrangement. This effect is considered to be in a first order. The model was applied to graphite , as an example, mainly because of its theoretical interest for wastewater electrochemical treatment.

Opening ParagraphIn the past anthropology was concerned with alien, exotic societies such as Indians, Africans, and Pacific Islanders. Today it is in vogue to do the anthropology of modern societies. Abroad this is termed the study of nation-building and development; at home it becomes the study of various sub-cultures with attention towards ethnic minorities and deviant groups rather than upon the more powerful and prominent segments of our society. Anthropologists tend to neglect those groups nearest themselves, and in the scurry to conduct relevant research, a broad area of great theoretical interest has been passed by. Almost no attention was ever paid by anthropologists to the study of colonial groups such as administrators, missionaries, or traders. Today we can read anthropological studies of the impact of such groups upon native populations, but the focus of such work dims with the colour line. Thus, an anthropologist has studied the machinations of the members of a Nigerian emirate but not the tactics of the British Resident and his staff. Another applied potted Weberian bureaucratic theory to Soga local government but neglected to discuss the British district officers in the same chiefdom. Another asked how Christian Tswana behaved, but not about those missionaries who had converted them. Anthropologists may have spoken about studying total societies, but they did not seem to consider their compatriots as subjects for wonder and analysis.* In the studies of Christianity in Africa, consideration was mainly in terms of the relations of the convert to his traditional society, to the process of social change, or sometimes to the development of native separatist churches. It never included the missionaries who had made the conversions or described everyday affairs at the mission station, clinic, or school.
