The evolution of modern human life history has involved substantial changes in the overall length of the subadult period, the introduction of a novel early childhood stage, and many changes in the initiation, termination, and character of the other stages. The fossil record is explored for evidence of this evolutionary process, with a special emphasis on middle childhood, which many argue is equivalent to the juvenile stage of African apes. Although the “juvenile” and “middle childhood” stages appear to be the (...) same from a broad comparative perspective, in that they begin with the eruption of the first molar and the achievement of the majority of adult brain size and end with sexual maturity, the detailed differences in the expression of these two stages, and how they relate to the preceding and following stages, suggest that a distinction should be maintained between them to avoid blurring subtle, but important, differences.

Evidence has accumulated that rod activation under mesopic and scotopic light levels alters visual perception and performance. Here we review the most recent developments in the measurement of rod and cone contributions to mesopic color perception and temporal processing, with a focus on data measured using the four-primary photostimulator method that independently controls rod and cone excitations. We discuss the findings in the context of rod inputs to the three primary retinogeniculate pathways to understand rod contributions to mesopic vision. Additionally, (...) we present evidence that hue perception is possible under scotopic, pure rod-mediated conditions that involves cortical mechanisms. (shrink)

What does it mean to be a peacemaker in a polarized world? It can feel as if the world-and the church-has never been more polarized. But when we feel worn down by the chasms dividing us, we can take hope from the early Christian vision of God uniting all things in Christ, a hope that can lead us to act. Stuck Together explores Bible stories and narratives ancient and modern that inspire us to open hearts and minds to persons with (...) whom we disagree as we gain confidence in our own convictions. Drawing from Scripture, from his own life journey, and from the witness of others, author J. Nelson Kraybill demonstrates how even small steps of reconciliation by confessionally grounded Christians can have big effect and give loving Christian witness in a polarized church and society.

Ushenko's speculative vision opened on the problem of time and its relation to logic. Profoundly concerned about the theme of time--the theme that intrinsically defines romantic irrationalism--he yet endeavored to vindicate within the bounds of temporality the sovereignty of logic so essential to the continuance of classical philosophy. The dual preoccupation with time and logic urged him into the fields of symbolic logic and relativity physics. From the flux of unrepeatable events he disengaged the laws of logic and the propositions (...) of scientific discourse, while at the same time he sought to keep both orders of entity united without injury to either. He ventured into nature as disclosed by contemporary physics and selected the category of event to supplant substance. He undertook to expound a metaphysics of events, grappled with the problem of the unity not only of nature but of the singular events that make up nature, and fixed upon the overarching structure of the space-time of relativity physics to resolve the problem. But this did not suffice. The metaphysical vision at work in these early books glimpsed at moments a principle beyond time, beyond propositions, beyond events--the principle of power. Power and Events: An Essay on Dynamics in Philosophy focused on the principle of power, integrating the other themes in terms of it. As the mature work of a significant and original thinker, Power and Events posed the principle of power as the central idea for the future course of philosophical investigation. In pursuit of its implications Ushenko embarked upon the philosophy of art in his last book Dynamics of Art and in a consistent yet startling fashion advanced the thesis that the substance of art is in effect a dynamic equilibrium of powers.

Some postcolonial theorists argue that the idea of a single system of belief known as "Hinduism" is a creation of nineteenth-century British imperialists. Andrew J. Nicholson introduces another perspective: although a unified Hindu identity is not as ancient as some Hindus claim, it has its roots in innovations within South Asian philosophy from the fourteenth to seventeenth centuries. During this time, thinkers treated the philosophies of Vedanta, Samkhya, and Yoga, along with the worshippers of Visnu, Siva, and Sakti, as (...) belonging to a single system of belief and practice. Instead of seeing such groups as separate and contradictory, they re-envisioned them as separate rivers leading to the ocean of Brahman, the ultimate reality. Drawing on the writings of philosophers from late medieval and early modern traditions, including Vijnanabhiksu, Madhava, and Madhusudana Sarasvati, Nicholson shows how influential thinkers portrayed Vedanta philosophy as the ultimate unifier of diverse belief systems. This project paved the way for the work of later Hindu reformers, such as Vivekananda, Radhakrishnan, and Gandhi, whose teachings promoted the notion that all world religions belong to a single spiritual unity. In his study, Nicholson also critiques the way in which Eurocentric concepts—like monism and dualism, idealism and realism, theism and atheism, and orthodoxy and heterodoxy—have come to dominate modern discourses on Indian philosophy.

The only collection of Mead's writings published during his lifetime, these essays have heretofore been virtually inaccessible. Reck has collected twenty-five essays representing the full range and depth of Mead's thought. This penetrating volume will be of interest to those in philosophy, sociology, and social psychology. "The editor's well-organized introduction supplies an excellent outline of this system in its development. In view of the scattered sources from which these writings are gathered, it is a great service that this volume renders (...) not only to students of Mead, but to historians."—H. W. Schneider, _Journal of the History of Philosophy_. (shrink)

Introduction: Philosophy in Spite of Itself Aristotle defines man as the political and rational animal, but the readings in this book are guided by his ...

Stressing the immediacy of Being, Hegel placed it categorially first in his logic. But the immediacy of Being, its presence no matter which content or lack of content be presented, signals a purity which ironically deprives it of every specific reality. Hence Hegel emphasized that Being, immediate and pure, is vacuous and collapses into Nothing. Extending a philosophical argument derived from Parmenides and Plato, Hegel further inferred Becoming from the dialectic of Being and Nothing, as though with static concepts he (...) could create the concrete flux.

Boodin's theory of knowledge was but a moment in an unfolding metaphysical system. Although Truth and Reality began with a plea for the toleration of different metaphysical interpretations, on the ground that each system is the result of the peculiar perspective afforded by the temperament of the particular philosopher, Boodin nevertheless promised in the "preface" to publish a metaphysics, entitled A Realistic Universe. This book was a bold philosophical adventure, because it claimed nothing less than the application of pragmatic method (...) to the task of constructing a metaphysical system. By this Boodin meant "... that we must judge the nature of reality, in its various grades and complexities, by the consequences to the realization of human purposes, instead of by a priori assumptions". "The only key we have to reality is what reality must be taken as in the progressive realization of the purposes of human nature". The synoptic vision afforded by metaphysics, inextricably linked to a conception of reality as that with which human purposes must cope, is moreover grounded in the procedures and results of the empirical sciences. "Whenever philosophy has been vital," Boodin wrote in the "Introduction" to the first edition of A Realistic Universe, "it has always followed close upon the heels of science and human interest.".

Schneider's History appeared at the right moment in America's cultural history. World War II had just ended; college enrollments were bursting with veterans curious about their heritage and anxious over their destiny; and the patriotic pride of an America emerging victoriously from war to take first place among the nations of the world found a partial outlet in those intellectual pursuits which inspired the introduction of college and university programs in American studies, on American history, American institutions, American literature, and (...) American thought. Above all, Schneider's book became the incomparable guide to the philosophic literature. If the reader was dismayed by Schneider's narrative, which was often too sketchy, sometimes too desultory, to portray the movement in and the depth of American thought, he could at least regale himself with the rich and copious bibliographies. Here, indeed, was food for thought, nurturing further research. (shrink)

_Offers a new perspective on the political significance of the Hegelian dialectical legacy._.

This volume consists of two lecture series given by Heidegger in the 1940s and 1950s. The lectures given in Bremen constitute the first public lectures Heidegger delivered after World War II, when he was officially banned from teaching. Here, Heidegger openly resumes thinking that deeply engaged him with Hölderlin's poetry and themes developed in his earlier works. In the Freiburg lectures Heidegger ponders thought itself and freely engages with the German idealists and Greek thinkers who had provoked him in the (...) past. Andrew J. Mitchell's translation allows English-speaking readers to explore important connections with Heidegger's earlier works on language, logic, and reality. (shrink)

REASON AND REVOLUTION, to which Henry F. May has called attention in his noteworthy book, The Enlightenment in America, mentioned in the first article in the present series, marks the period of American colonial history from 1763 to 1776. The Declaration of Independence, I have maintained, is a consummate expression of these Enlightenment features, influenced by the thought of John Locke and others in philosophy. From cautious moderation the American movement of protest against British rule climaxed in a revolution. The (...) dynamic structure of the epoch unfolded as a kind of sorites, of which the major premises are a general philosophy of rights and a particular theory of the British Empire, the minor premises are numerous allegedly factual violations of these theoretical premises, and the conclusion is a decisive act of separation or independence. Since, however, the Enlightenment mode of revolution rested, to reiterate May's statement, on "the belief in the possibility of constructing a new heaven and earth out of the destruction of the old," the moment in history expressed by the Declaration of Independence logically leads to other moments, one of which is the formation of the American republic as both a federal and national union. This singular moment is crystallized in the Constitution of the United States, a document equal in importance to the Declaration of Independence as a symbol of the Enlightenment. (shrink)

MICHAEL KAMMEN in his book, A Machine That Would Go of Itself, has provided a comprehensive but highly readable history of the role of the Constitution in American culture. He has commented, with notable insight, on the capacity of Americans "to view their Constitution with a vision that was occasionally clouded and frequently bifocal: bifocal in the sense that the Constitution as a cultural symbol, rationalized in various ways, could be seen on a separate plane--or literally through a discrete lens--from (...) the Constitution as a 'practical system.' " While Kammen has devoted much detailed attention to "that discrepancy between the applied Constitution and the symbolic constitution," the bulk of his large book centers on the role of the Constitution as cultural icon. In this paper I shall explore what the Constitution as icon represents, although I shall also attend to some critical facets of the Constitution as a practical system. What the Constitution symbolizes has been a major moral and intellectual strand threading together the fabric of Western civilization from antiquity to the present. (shrink)

REASON, SKEPTICISM, REVOLUTION, AND COMMON SENSE--these are the four characteristics which Henry F. May has found to designate the four categories, or stages, in the development of the Enlightenment in Europe and America. These categories, useful for the classification, description, and analysis of the copious intellectual and cultural materials which comprise the Enlightenment, overlap in the formulation of basic documents--the Declaration of Independence, the Constitution of the United States, and the Bill of Rights, which are fundamental American laws. The interweaving (...) of reason and revolution in the Declaration of Independence and the Constitution of the United States has been examined by direct references to the European philosophers whose ideas were employed, with modifications, and implemented by means of newly invented institutions on the part of the American founders. The ideas of Locke, Montesquieu, Burlamaqui, Hutcheson, Hume, and many other thinkers, became instruments of political change in the hands of the Americans. Revolution, moderated by reason and common sense, led to constitution, in order to secure the gains of revolution. (shrink)

THE ENLIGHTENMENT IS DISTINGUISHED from other periods of history by two major characteristics: 1) the widespread belief that it was superior morally and intellectually to all those periods which preceded it, and 2) the conviction that human faculties, reason or moral sense, are primarily responsible for this achievement. The Enlightenment was marked, furthermore, by radical change in the organization of society and by rapid progress in the applications of scientific technology to the production of goods and services. Since political and (...) ecclesiastical authorities were challenged during the Enlightenment, revolutions, both democratic and industrial, have been its fruit. Inherited traditions and established institutions were often overthrown or overhauled in order to release the human energies, ideas, and values which promoted the erection of new institutions.

Empirical work has lately confirmed what many philosophers have taken to be true: people are ‘biased toward the future’. All else being equal, we usually prefer to have positive experiences in the future, and negative experiences in the past. According to one hypothesis, the temporal metaphysics hypothesis, future-bias is explained either by our beliefs about temporal metaphysics—the temporal belief hypothesis—or alternatively by our temporal phenomenology—the temporal phenomenology hypothesis. We empirically investigate a particular version of the temporal belief hypothesis according to (...) which future-bias is explained by the belief that time robustly passes. Our results do not match the apparent predictions of this hypothesis, and so provide evidence against it. But we also find that people give more future-biased responses when asked to simulate a belief in robust passage. We take this to suggest that the phenomenology that attends simulation of that belief may be partially responsible for future-bias, and we examine the implications of these results for debates about the rationality of future-bias.

There are two kinds of time-bias: near-bias and future-bias. While philosophers typically hold that near-bias is rationally impermissible, many hold that future-bias is rationally permissible. Call this normative hybridism. According to arbitrariness objections, certain patterns of preference are rationally impermissible because they are arbitrary. While arbitrariness objections have been levelled against both near-bias and future-bias, the kind of arbitrariness in question has been different. In this paper we investigate whether there are forms of arbitrariness that are common to both kinds (...) of preferences, and hence whether there are versions of the arbitrariness objection that are objections both to near-bias and future-bias. If there are, then this might go some way towards undermining normative hybridism and to defending a thorough-going time-neutralism. (shrink)

We investigated, experimentally, the contention that the folk view, or naïve theory, of time, amongst the population we investigated is dynamical. We found that amongst that population, ~ 70% have an extant theory of time that is more similar to a dynamical than a non-dynamical theory, and ~ 70% of those who deploy a naïve theory of time deploy a naïve theory that is more similar to a dynamical than a non-dynamical theory. Interestingly, while we found stable results across our (...) two experiments regarding the percentage of participants that have a dynamical or non-dynamical extant theory of time, we did not find such stability regarding which particular dynamical or non-dynamical theory of time they take to be most similar to our world. This suggests that there might be two extant theories in the population—a broadly dynamical one and a broadly non-dynamical one—but that those theories are sufficiently incomplete that participants do not stably choose the same dynamical theory as being most similar to our world. This suggests that while appeals to the ordinary view of time may do some work in the context of adjudicating disputes between dynamists and non-dynamists, they likely cannot do any such work adjudicating disputes between particular brands of dynamism.
