In this review, we describe some of the central philosophical issues facing origins-of-life research and provide a targeted history of the developments that have led to the multidisciplinary field of origins-of-life studies. We outline these issues and developments to guide researchers and students from all fields. With respect to philosophy, we provide brief summaries of debates with respect to (1) definitions (or theories) of life, what life is and how research should be conducted in the absence of an accepted theory (...) of life, (2) the distinctions between synthetic, historical, and universal projects in origins-of-life studies, issues with strategies for inferring the origins of life, such as (3) the nature of the first living entities (the “bottom up” approach) and (4) how to infer the nature of the last universal common ancestor (the “top down” approach), and (5) the status of origins of life as a science. Each of these debates influences the others. Although there are clusters of researchers that agree on some answers to these issues, each of these debates is still open. With respect to history, we outline several independent paths that have led to some of the approaches now prevalent in origins-of-life studies. These include one path from early views of life through the scientific revolutions brought about by Linnaeus (von Linn.), Wöhler, Miller, and others. In this approach, new theories, tools, and evidence guide new thoughts about the nature of life and its origin.We also describe another family of paths motivated by a” circularity” approach to life, which is guided by such thinkers as Maturana & Varela, Gánti, Rosen, and others. These views echo ideas developed by Kant and Aristotle, though they do so using modern science in ways that produce exciting avenues of investigation. By exploring the history of these ideas, we can see how many of the issues that currently interest us have been guided by the contexts in which the ideas were developed. The disciplinary backgrounds of each of these scholars has influenced the questions they sought to answer, the experiments they envisioned, and the kinds of data they collected. We conclude by encouraging scientists and scholars in the humanities and social sciences to explore ways in which they can interact to provide a deeper understanding of the conceptual assumptions, structure, and history of origins-of-life research. This may be useful to help frame future research agendas and bring awareness to the multifaceted issues facing this challenging scientific question. (shrink)

The question of the causality exercised by active mind cannot be dismissed as an attempt to go beyond what Aristotle explicitly says. One cannot say that Aristotle proves the existence of active mind but leaves the kind of causality it exercises an open question. Rather, if one accepts that Aristotle proves the existence of active mind, one must have an answer for the kind of causality it exercises. The analysis of De Anima, 3.5 shows that the principle on which the (...) argument for the existence of active mind rests cannot be read as arguing coherently for the existence of active mind as an efficient cause, but that the text is open to an interpretation along the lines of final causality.

Why does one theory "succeed" while another, possibly clearer interpretation, fails? By exploring two observationally equivalent yet conceptually incompatible views of quantum mechanics, James T. Cushing shows how historical contingency can be crucial to determining a theory's construction and its position among competing views. Since the late 1920s, the theory formulated by Niels Bohr and his colleagues at Copenhagen has been the dominant interpretation of quantum mechanics. Yet an alternative interpretation, rooted in the work of Louis de Broglie in (...) the early 1920s and reformulated and extended by David Bohm in the 1950s, equally well explains the observational data. Through a detailed historical and sociological study of the physicists who developed different theories of quantum mechanics, the debates within and between opposing camps, and the receptions given to each theory, Cushing shows that despite the preeminence of the Copenhagen view, the Bohm interpretation cannot be ignored. Cushing contends that the Copenhagen interpretation became widely accepted not because it is a better explanation of subatomic phenomena than is Bohm's, but because it happened to appear first. Focusing on the philosophical, social, and cultural forces that shaped one of the most important developments in modern physics, this provocative book examines the role that timing can play in the establishment of theory and explanation.

From the beginning, the implications of quantum theory for our most general understanding of the world have been a matter of intense debate. Einstein argues that the theory had to be regarded as fundamentally incomplete. Its inability, for example, to predict the exact time of decay of a single radioactive atom had to be due to a failure of the theory and not due to a permanent inability on our part or a fundamental indeterminism in nature itself. In 1964, John (...) Bell derived a theorem which showed that any deterministic theory which preserved locality would have certain consequences for measurements performed at a distance from one another. An experimental check seems to show that these consequences are not, in fact, realized. The correlation between the sets of events is much stronger than any local deterministic theory could allow. What is more, this stronger correlation is precisely that which is predicted by quantum theory. The astonishing result is that local deterministic theories of the classical sort seem to be permanently excluded. Not only can the individual decay not be predicted, but no future theory can ever predict it. The contributors in this volume wrestle with this conclusion. Some welcome it; others leave open a return to at lease some kind of deterministic world, one which must however allow something like action-at-a distance. How much lit it? And how can one avoid violating relativity theory, which excludes action-at-a-distance? How can a clash between the two fundamental theories of modern physics, relativity and quantum theory, be avoided? What are the consequences for the traditional philosophic issue of causality explanation and objectivity? One thing is certain; we can never return to the comfortable Newtonian world where everything that happened was, in principle, predictable and where what happened at one measurement site could not affect another set of measurements being performed light-years away, at a distance that a light-signal could not bridge.

Intellectual history and the history of political thought are siblings, perhaps even twins. They have similar origins and use similar materials. They attract many of the same friends and make some of the same enemies. Yet like most siblings, they have different temperaments and ambitions. This essay explores the family resemblances and draws out the contrasts by examining two major works by one of the most prominent political theorists of the past half-century, Alan Ryan, who has recently published two big (...) books that intellectual historians will find rewarding and provocative.

We are often told that quantum phenomena demand radical revisions of our scientific world view and that no physical theory describing well defined objects, such as particles described by their positions, evolving in a well defined way, let alone deterministically, can account for such phenomena. The great majority of physicists continue to subscribe to this view, despite the fact that just such a deterministic theory, accounting for all of the phe nomena of nonrelativistic quantum mechanics, was proposed by David Bohm (...) more than four decades ago and has arguably been around almost since the inception of quantum mechanics itself. Our purpose in asking colleagues to write the essays for this volume has not been to produce a Festschrift in honor of David Bohm or to gather together a collection of papers simply stating uncritically Bohm's views on quantum mechanics. The central theme around which the essays in this volume are arranged is David Bohm's version of quantum mechanics. It has by now become fairly standard practice to refer to his theory as Bohmian mechanics and to the larger conceptual framework within which this is located as the causal quantum theory program. While it is true that one can have reservations about the appropriateness of these specific labels, both do elicit distinc tive images characteristic of the key concepts of these approaches and such terminology does serve effectively to contrast this class of theories with more standard formulations of quantum theory.

One of the major philosophical problems in physical sciences is what criteria should determine how scientific theories are selected and justified in practice and whether, in describing observable physical phenomena, such theories are effectively constrained to be unique. This book studies the example of a particular theory, the S-matrix theory. The S-matrix program was initiated by Heisenberg to deal with difficulties encountered in quantum field theories in describing particular phenomena. Since then, each theory has at different times been favored as (...) the explanation of observed phenomena. Certainly the S-matrix theory was adequate, feasible and fertile. However, the quantum field theory interpretation is now widely accepted and the study of alternative theories is all but abandoned. By examining the philosophy which influenced the turns in this story, the author explains how an adequate and viable theory fell out of favor and concludes with a critique of different methodologies in the history of science.

The task of visual search is to determine as rapidly as possible whether a target item is present or absent in a display. Rapidly detected items are thought to contain features that correspond to primitive elements in the human visual system. In previous theories, it has been assumed that visual search is based on simple two-dimensional features in the image. However, visual search also has access to another level of representation, one that describes properties in the corresponding three-dimensional scene. Among (...) these properties are three dimensionality and the direction of lighting, but not viewing direction. These findings imply that the parallel processes of early vision are much more sophisticated than previously assumed. (shrink)

This book examines a selection of philosophical issues in the context of specific episodes in the development of physical theories. Advances in science are presented against the historical and philosophical backgrounds in which they occurred. A major aim is to impress upon the reader the essential role that philosophical considerations have played in the actual practice of science. The book begins with some necessary introduction to the history of ancient and early modern science, with major emphasis being given to the (...) two great watersheds of twentieth-century physics: relativity and, especially, quantum mechanics. At times the term 'construction' may seem more appropriate than 'discovery' for the way theories have developed and, especially in the later chapters, the question of the influence of historical, philosophical and even social factors on the very form and content of scientific theories is discussed.

This article investigates the key aspects of the Confucian virtue ethics such as the "chun- tzu" (Superior Person), the Five Relationships of society, the particular Confucian virtues of "jen" (benevolence) and "li" (propriety), the moral vision of the "tao" (Way), and the understanding of the "t'ien- ming" (Mandate of Heaven). The thesis of the article is that the moral matrix provided by the web of social relationships allows the Confucian ethics of virtue to function well, and that a consideration of (...) this Confucian moral matrix may illuminate the Western debate on the ethics of virtue vs the ethics of duty.

Previous theories of early vision have assumed that visual search is based on simple two-dimensional aspects of an image, such as the orientation of edges and lines. It is shown here that search can also be based on three-dimensional orientation of objects in the corresponding scene, provided that these objects are simple convex blocks. Direct comparison shows that image-based and scene-based orientation are similar in their ability to facilitate search. These findings support the hypothesis that scene-based properties are represented at (...) preattentive levels in early vision. (shrink)

Empirical adequacy, formal explanation and understanding are distinct goals of science. While no a priori criterion for understanding should be laid down, there may be inherent limitations on the way we are able to understand explanations of physical phenomena. I examine several recent contributions to the exercise of fashioning an explanatory discourse to mold the formal explanation provided by quantum mechanics to our modes of understanding. The question is whether we are capable of truly understanding (or comprehending) quantum phenomena, as (...) opposed to simply accepting the formalism and certain irreducible quantum correlations. The central issue is that of understanding versus merely redefining terms to paper over our ignorance. (shrink)

A case study of the development of quantum field theory and of S-matrix theory, from their inceptions to the present, is presented. The descriptions of science given by Kuhn and by Lakatos are compared and contrasted as they apply to this case study. The episodes of the developments of these theories are then considered as candidates for competing research programs in Lakatos' methodology of scientific research programs. Lakatos' scheme provides a reasonable overall description and a plausible assessment of the relative (...) value of these two programs in terms of progressive and degenerating problem shifts. Also discussed are the roles of various types of models as they have been used in these areas of theoretical high-energy physics. (shrink)

It has generally been assumed that rapid visual search is based on simple features and that spatial relations between features are irrelevant for this task. Seven experiments involving search for line drawings contradict this assumption; a major determinant of search is the presence of line junctions. Arrow- and Y-junctions were detected rapidly in isolation and when they were embedded in drawings of rectangular polyhedra. Search for T-junctions was considerably slower. Drawings containing T-junctions often gave rise to very slow search even (...) when distinguishing arrow- or Y-junctions were present. This sensitivity to line relations suggests that preattentive processes can extract 3-dimensional orientation from line drawings. A computational model is outlined for how this may be accomplished in early human vision. (shrink)

An exploration of the moral and ethical implications of new biotechnologies Many of the ethical issues raised by new technologies have not been widely examined, discussed, or indeed settled. For example, robotics technology challenges the notion of personhood. Should a robot, capable of making what humans would call ethical decisions, be held responsible for those decisions and the resultant actions? Should society reward and punish robots in the same way that it does humans? Likewise, issues of safety, environmental concerns, and (...) distributive justice arise with the increasing acceptance of genetically modified organisms in food production nanotechnology in engineering and medicine, and human gene therapy and enhancement. The problem of dual-use—when a technology can be used both to benefit and to harm—exists with virtually all new technologies but is central in the context of emerging 21st century technologies ranging from artificial intelligence and robotics to human gene-editing and brain-computer interfacing. In Re-Creating Nature: Science, Technology, and Human Values in the Twenty-First Century, James T. Bradley addresses emerging biotechnologies with prodigious potential to benefit humankind but that are also fraught with ethical consequences. Some actually possess the power to directly alter the evolution of life on earth including human. Specifically, these topics include stem cells, synthetic biology, GMOs in agriculture, nanotechnology, bioterrorism, CRISPR gene-editing technology, three-parent babies, robotics and roboethics, artificial intelligence, and human brain research and neurotechnologies. Offering clear explanations of these various technologies, a pragmatic presentation of the conundrums involved, and questions that illuminate hypothetical situations, Bradley guides discussions of these and other thorny issues resulting from the development of new biotechnologies. He also highlights the responsibilities of scientists to conduct research in an ethical manner and the responsibilities of nonscientists to become “science literate” in the twenty-first century.

The Handbook of Roman Catholic Moral Terms contains more than 800 moral terms, offering concise definitions, historical context, and illustrations of how these terms are used in the Catholic tradition, including Church teaching and documents. James T. Bretzke, SJ, places Catholic tradition in a contemporary context in order to illuminate the continuities as well as discontinuities of Church teaching and key directions of Catholic thought. The author also provides extensive cross-referencing and bibliographic suggestions for further research. Designed to serve (...) as a vital reference work for libraries, students and scholars of theology, priests and pastoral ministers, as well as all adults interested in theological enrichment or continuing education, the Handbook of Roman Catholic Moral Terms is the most comprehensive post–Vatican II work of its kind available in English.

I don’t think Lynne Rudder Baker’s constitution view can account for personal identity problems of a synchronic or diachronic nature. As such, it cannot accommodate the Christian’s claim of eschatological bodily resurrection-a principle reason for which she gives this account. In light of this, I press objections against her constitution view in the following ways: First, I critique an analogy she draws between Aristotle’s “accidental sameness” and constitution. Second, I address three problems for Baker’s constitution view [‘Constitution Problems’ ], each (...) more problematic than the next: CP1: Her definition of constitution lacks explanatory power; CP2: If there is a plausible definition of constitution, constitution implies either too many persons or no human persons at all; CP3: Constitution yields no essential distinction between human and divine persons. If my argument go through, her constitution view has neither an explanation for diachronic personal identity nor personal identity through resurrection. (shrink)

In the philosophy of science, we are to assess critically and on their intrinsic merits various proposals for a consistent interpretation of quantum mechanics, including resolutions of the measurement problem and accounts of the long-range Bell correlations. In this paper I suggest that the terms of debate may have been so severely and unduly constrained by the reigning orthodoxy that we labor unproductively with an unhelpful vocabulary and set of definitions and distinctions. I present an alternative conceptual framework, free of (...) many of the standard conundrums. (shrink)

Christian tradition has largely held three affirmations on the resurrection of the physical body. Firstly, that bodily resurrection is not a superfluous hope of afterlife. Secondly, there is immediate post-mortem existence in Paradise. Finally, there is numerical identity between pre-mortem and post-resurrection human beings. The same tradition also largely adheres to a robust doctrine of The Intermediate State, a paradisiacal disembodied state of existence following the biological death of a human being. This book argues that these positions are in fact (...) internally inconsistent, and so a new metaphysics for life after death is required. (shrink)

In the sixteenth century, Sir Thomas More criticized Martin Luther’s purported denial of a conscious intermediate state between bodily death and bodily resurrection. In the same century, William Tyndale penned a response in defense of Luther’s view. His argument essentially defended the proposition: If the Intermediate State obtains, then bodily resurrection is superfluous for those in the paradisiacal state. In this article, I enter the fray and argue for the truth of this conditional claim. And, like William Tyndale, I use (...) the content and argument of a particular chapter in the Bible, namely, 1 Corinthians 15, to make the point. (shrink)
