This paper emphasizes the crucial role of variation, at several different levels, for a detailed historical understanding of the development of the biomedical sciences. Going beyond valuable recent studies that focus on model organisms, experimental systems and instruments, we argue that all of these categories can be accommodated within our approach, which pays special attention to organismal and cultural variation. Our empirical examples are drawn in particular from recent historical studies of nineteenth- and early twentieth-century genetics and physiology. Based on (...) the quasi-paradoxical conclusion that biological and cultural variation both constrains and enables innovation in the biomedical sciences, we argue that more attention should be paid to variation as an analytical category in the historiography of the life sciences.

A theory is presented to explain how accurate, single-joint movements are controlled. The theory applies to movements across different distances, with different inertial loads, toward targets of different widths over a wide range of experimentally manipulated velocities. The theory is based on three propositions. (1) Movements are planned according to “strategies” of which there are at least two: a speed-insensitive (SI) and a speed-sensitive (SS) one. (2) These strategies can be equated with sets of rules for performing diverse movement tasks. (...) The choice between SI and SS depends on whether movement speed and/or movement time (and hence appropriate muscle forces) must be constrained to meet task requirements. (3) The electromyogram can be interpreted as a low-pass filtered version of the controlling signal to the motoneuron pools. This controlling signal can be modelled as a rectangular excitation pulse in which modulation occurs in either pulse amplitude or pulse width. Movements to different distances and with loads are controlled by the SI strategy, which modulates pulse width. Movements in which speed must be explicitly regulated are controlled by the SS strategy, which modulates pulse amplitude. The distinction between the two movement strategies reconciles many apparent conflicts in the motor control literature. (shrink)

This article presents six ideas about the construction of emotion: (a) Emotions are more readily distinguished by the situations they signify than by patterns of bodily responses; (b) emotions emerge from, rather than cause, emotional thoughts, feelings, and expressions; (c) the impact of emotions is constrained by the nature of the situations they represent; (d) in the OCC account (the model proposed by Ortony, Clore, and Collins in 1988), appraisals are psychological aspects of situations that distinguish one emotion from another, (...) rather than triggers that elicit emotions; (e) analyses of the affective lexicon indicate that emotion words refer to internal mental states focused on affect; (f) the modularity of emotion, long sought in biology and behavior, exists as mental schemas for interpreting human experience in story, song, drama, and conversation.

In this article, we examine how affect influences judgment and thought, but also how thought transforms affect. The general thesis is that the nature and impact of affective reactions depends largely on their objects. We view affect as a representation of value, and its consequences as dependent on its object or what it is about. Within a review of relevant literature and a discussion of the nature of emotion, we focus on the role of the object of affect in governing (...) both the nature of emotional reactions and the impact of affect and emotion on cognition and action. Although emotion is always about the here and now, the capacity for abstract thought means that the human here and now includes imagination as well as perception. Indeed, the hopes and fears that dominate human lives often involve things only imagined. (shrink)

This book concerns the relationship between language and poetry in Heidegger's later writings. Gerald L. Bruns illuminates these difficult and strange writings by analyzing his style and form and by reflecting on the philosopher's insights.

Sharon Street’s 2006 article “A Darwinian Dilemma for Realist Theories of Value” challenges the epistemological pretensions of the moral realist, of the nonnaturalist in particular. Given that “Evolutionary forces have played a tremendous role in shaping the content of human evaluative attitudes” – why should one suppose such attitudes and concomitant beliefs would track an independent moral reality? Especially since, on a nonnaturalist view, moral truth is causally inert. I abstract a logical skeleton of Street’s argument and, with its aid, (...) focus on problematic assumptions regarding the (a)causality of moral truth. It emerges that there are acquired causal powers that compensate for the intrinsic impotence of moral truth, as well as two distinct levels at which truth-tracking might occur. I argue that while evolution’s selective forces do not track moral truth, that does not imply individual organisms could not have evolved that capability. -/- . (shrink)

Some 1600 years separate our world from the world of the Desert Fathers and Mothers, a world that might seem strange to us. There is much in it that does in fact seem disturbing and bizarre, especially the strict asceticism that drove these unusual saints into the wilderness. Their worldview becomes more accessible and relevant, however, if we grasp the underlying psychology of the movement, especially as it was explored and explained by one of the great theologians of the movement, (...) Evagrius Ponticus. His description of the human soul and the eight deadly “thoughts” manifest a psychology that shows why the Desert Fathers and Mothers withdrew into the desert to fight the devil, seek for God, and practice the ascetic disciplines with such ferocity. The “Sayings” of the tradition show how it is possible to overcome these deadly thoughts. It is obvious that grace is needed, an appropriate setting, and spiritual discipline, which includes asceticism, to be sure, but also a calm attentiveness to God and genuine love. (shrink)

Over the past two centuries historians of Christianity have offered various theories concerning why and how the early Christian movement took root and flourished in the Greco-Roman world, which was surprising considering its modest beginning, its small size, its lack of cultural resources, and its bad reputation among the elites. This article argues that the formation of the early Christian catechumenate enabled the church not only to reach pagans but to transition them to the very different world of Christianity and (...) to keep them in that world. The catechumenate was necessary because the difference between paganism and Christianity was great enough to require that some kind of bridge be built between the two worlds if Christians hoped to win new converts to the faith and then establish them securely in that faith, and it was effective because it struck just the right balance between making Christianity attractive and accessible and yet setting high standards for membership, which in the long run made the church leaner and stronger.

Thomas Kuhn's thesis concerning the structure of scientific change was critically examined in relation to the historical problems of social science. The use and interpretation of Kuhn's ideas by psychologists was reviewed and found to center around the proliferation of theoretical views as paradigms, the viewing of theoretical differences as paradigm clashes, and efforts to affirm particular conceptions of psychology's past or future. Such use was seen as curbing discussion of fundamental issues, and to reflect a continuing neglect of the (...) foundational problems peculiar to social science. The relevance of Kuhn's work was seen to rest on a more critical view of his idea of “mature” science, better understanding of the type of social psychology upon which his thesis rests, and greater appreciation of his hermeneutic approach to social-historical analysis.

Thus it would not be the content or meaning of a written Torah that Jeremiah would attack; rather it would be the Deuteronomic “claim to final and exclusive authority by means of writing” . Jeremiah’s problem is political rather than theological. He knows that writing is more powerful than prophecy and that he will not be able to withstand it—and he knows that the Deuteronomists know no less. As Blenkinsopp says, “Deuteronomy produced a situation in which prophecy could not continue (...) to exist without undergoing profound transformations” —that is, without ceasing to be “free prophecy,” or prophecy unbound by any text, including its own. “It might be considered misleading or flippant to say that for [Deuteronomy], as for rabbinic orthodoxy, the only good prophet is a dead prophet. But in point of fact the Deuteronomic scribes, despite their evident debt to and respect for the prophets, contributed decisively to the eclipse of the kind of historically oriented prophecy represented by Jeremiah and the emergence in due course of quite different forms of scribal prophecy” .It is at this point that we reach a sort of outer limit of biblical criticism—a threshold that scholars, with their foundations in literary criticism, their analytical attitude toward texts, and their theological concerns, are not inclined to cross. In any case, it is no accident that the political meaning of the conflict of prophecy and canon has received its most serious attention not from a biblical scholar but from a radical historian, Ellis Rivkin. In The Shaping of Jewish History, a brilliant and tendentious book, Rivkin proposes to treat the question of canon-formation and the promulgation of canonical texts of the Scriptures, not according to literary criteria but according to power criteria. For Rivkin, the production of the Hebrew Scriptures “was not primarily the work of scribes, scholars, or editors who sought out neglected traditions about wilderness experience, but of a class struggling to gain power.”23 23.

Models of central control variables (CVs) that are expressed in positional reference frames and rely on proprioception as the dominant specifier of muscle activation patterns have not yet been shown to be adequate for the description of fast, voluntary movement, even of single joints. An alternative model with illustrative data is proposed.
