Abstract. For the past two decades, I have been developing an integrative Christian marriage theory, based in part on a grounding concept of natural law and an overarching theory of covenant. The natural law part of this theory starts with an account of the natural facts, conditions, interests, needs, and qualities of human life, interaction, and generation—what I call the “premoral” goods or realities of life. It then identifies the natural inclinations of humans to form enduring and exclusive monogamous marriages (...) and to preserve these units as the central site for intimacy, procreation, and nurture of children. In this paper, I first summarize this natural law theory of marriage and then compare it to the formulations of other modern Christian thinkers. I also defend this theory against various modern critics of natural law—in part by reinterpreting some traditional natural law teachings that in my view have been misunderstood, in part by looking at the interesting convergences between the insights into sex, marriage, and family life offered by contemporary Christian theological ethicists and by evolutionary biologists and biological anthropologists.

That the rationality of individual people is ‘bounded’ – that is, finite in scope and representational reach, and constrained by the opportunity cost of time – cannot reasonably be controversial as an empirical matter. In this context, the paper addresses the question as to why, if economics is an empirical science, economists introduce bounds on the rationality of agents in their models only grudgingly and partially. The answer defended in the paper is that most economists are interested primarily in markets (...) and only secondarily in the dynamics of individual decisions – specifically, they are interested in these dynamics mainly insofar as they might systematically influence the most useful approaches to modeling interesting markets. In market contexts, bounds on rationality are typically generated by institutional and informational properties specific to the market in question, which arise and are sustained by structural dynamics that do not originate in or reduce to individuals' decisions or psychologic..

ABSTRACT: A popular response to proponents of embryonic stem cell research and advocates of abortion rights alike-summarized by claims such as “you came from an embryo!” or “you were a fetus once!”-enjoys a rich philosophical pedigree in the arguments of Hare, Marquis, and others. According to such arguments from potentiality, the prenatal human organism is morally valuable because every person’s biological history depends on having completed embryonic and fetal stages. In this article I set out the steps of the underlying (...) argument in light of how it has been cast in the philosophical literature and uncover an intriguingly illicit inference.RÉSUMÉ: On répond souvent aux avocats de la recherche sur les cellules souches et à ceux du droit a l’avortement par une argumentation qui se résume à des affirmations comme : «vous provenez d’un embryon!» ou «vous avez déjà été un fœtus!» -- ce genre de réponse appartient à une riche lignée philosophique qui inclut les arguments de Hare, Marquis et d’autres encore. Selon ces arguments fondés sur la potentialité, l’organisme humain prénatal possède une valeur morale parce que l’histoire biologique de chaque personne dépend de l’accomplissement des états embryonnaire et fœtal. Je présente ici les étapes du raisonnement qui se trouve au fondement de cette argumentation telle qu’elle est formulée dans la littérature philosophique. J’y découvre une inférence curieusement invalide. (shrink)

This paper suggests that the flaw in the enthymeme approach to argument analysis is in the requirement, as I come to formulate it, that an argument be restated as a premises-and-conclusion sequence. The paper begins by investigating how logicians show that there are problems with the enthymeme approach. That investigation reveals a failure on the part of logicians to appreciate the importance of the rhetorical context of an argument. This failure, it is argued, is a consequence of what I refer (...) to as the Premise-Conclusion Requirement. (shrink)

This paper investigates an important aspect of mathematical practice: that proof is required for a finished piece of mathematics. If follows that non-deductive arguments — however convincing — are never sufficient. I explore four aspects of mathematical research that have facilitated the impressive success of the discipline. These I call the Practical Virtues: Permanence, Reliability, Autonomy, and Consensus. I then argue that permitting results to become established on the basis of non-deductive evidence alone would lead to their deterioration. This furnishes (...) us with a partial rational justification for mathematicians strict insistence on proof. (shrink)

This paper objects to treating begging the question as circular reasoning. It argues that what is at issue in the argument is not to be confused with the claim or position that the arguer is adopting, and that logicians from Aristotle on give the wrong definition and have difficulty making sense of the fallacy because they try to define it in terms of how an argument is defined by logical theory - as a sequence consisting of premises followed by a (...) conclusion. That the problematic about begging the question depends on treating an argument as a context-less sequence of statements seems to be anticipated by the pragma-dialectical approach. The paper offers a critique of this dialogical approach, as exemplified by Douglas Walton in his recent book on begging the question, on the grounds that it raises more problems than it solves. It concludes with the suggestion that what is really at issue in discussions of begging the question is the need for a theory of fallacy. (shrink)

This volume contributes to postphenomenological research into human-technology relations with essays reflecting on methodological issues through empirical studies of education, digital media, biohacking, health, robotics, and skateboarding. This work provides new perspectives that call for a comprehensive postphenomenological research methodology.

We address the need for a model by considering two competing theories regarding the origin of life: (i) the Metabolism First theory, and (ii) the RNA World theory. We discuss two interrelated points, namely: (i) Models are valuable tools for understanding both the processes and intricacies of origin-of-life issues, and (ii) Insights from models also help us to evaluate the core objection to origin-of-life theories, called “the inefficiency objection”, which is commonly raised by proponents of both the Metabolism First theory (...) and the RNA World theory against each other. We use Simpson’s Paradox (SP) as a tool for challenging this objection. We will use models in various senses, ranging from taking them as representations of reality to treating them as theories/accounts that provide heuristics for probing reality. In this paper, we will frequently use models and theories interchangeably. Additionally, we investigate Conway’s Game of Life and contrast it with our SP-based approach to emergence-of-life issues. Finally, we discuss some of the consequences of our view. A scientific model is testable in three senses: (i) a logical sense, (ii) a nomological sense, and (iii) a current technological sense. The SP-based model is testable in the first two senses but it is not feasible to test it using current technology. (shrink)

“Reply to My Interlocutors” responds to each contributor, not in order in the text, but in order of issues. Each interlocutor deals with important issues and I situate myself in relation to these. Dealing with Husserl from a twenty-first century position has called for a multiple layered time response, since I find much of his philosophy of science highly outdated. The origins of the various chapters take place over several decades of time.

Frank Ebersole's extraordinary investigations of certain key philosophical ideas behind problems in epistemology and metaphysics are the subject of this article-review. I have resisted providing what many readers will expect me to provide, namely, a critical examination of his philosophical methodology. I do question his unwilligness to say why his investigations only yield I negative results, and I do have something to say about classifying him as an ordinary language philosopher. However, my main focus is on trying to engage critically (...) with what he actually does in his work. To this end, I provide a narrative of the investigation he carries out into the possibility of comparing the objects of perception and dreams, and I cite other works of his in support of my understanding of that investigation. Although one of his lengthiest essays seems to be devoted to an anticipation of an objection to his approach, I explain why even there he is not concerned with the question of why he always seems to get negative results. After suggesting why some of his later essays seem to be so hard to read, I conclude by saying something about what I take to be his achievement. (shrink)

Intuitively, rape is seriously morally wrong in a way simple assault is not. Yet philosophical disputes about the features of rape that make it the heinous act it is invite a general account of the difference between (mere) wrong-making characteristics and heinous-making characteristics. In this paper I propose just such an account and use it to refute some accounts of the wrongness of rape and refine others. Given these analyses, I close by developing and defending an account of a particularly (...) important heinous-making characteristic of rape. (shrink)

It is an honor to receive such extensive comments from Louis Loeb, whose work I admire and from whom I have learned much. In particular, his landmark 2002 book, Stability and Justification in Hume’s “Treatise” and his 2010 collection of essays, Reflection and the Stability of Belief: Essays on Descartes, Hume, and Reid are essential reading for anyone who wants to understand early modern epistemology. Some of what I have learned from him is reflected in the book on which he (...) is now commenting which is not, of course, to say that he approves of all of the uses I make of his work, nor that I agree...

The dominant notions of consciousness in the West are anchored in a peculiar matrix of dissociated sensibility held in place by unthematized body practices. It is misleading to evaluate spiritual and philosophical notions of consciousness simply from the point of view of verbal, logical analysis, when they are expressions of these deeply rooted experiential sensibilities, deliberately cultivated over long years of habituation. There is a dramatic difference between how the West thinks of body practices as irrelevant to analyzing states of (...) consciousness and how other cultures make direct links between these practices and the shaping of consciousness. For at least the last 150 years in Europe and the United States a number of teachers have developed body practices in deliberate resistance to the dualistic structurings of mentalities and physicality. They constitute a cultural movement of resistance shaped by the recognition of the mistaken notions embodied in Western dualism. An example is given of the work of Bonnie Bainbridge Cohen, the creator of the School of Body‐Mind Centering. Key Words: Embodiment, Somatics, Cultivation, Practices, Dualism. (shrink)

The ad baculum is not a fallacy in an argument, but is offered instead of an argument to put an end to further argument. This claim is the basis for criticizing Michael Wreen's "neo-traditionalism," which yields misreadings of supposed cases of the ad baculum because of its rejection of any consideration of what the person using the ad baculum, or someone who refers to that use as an "argument," is doing. The paper concludes with reflections on the values that should (...) inform talk of a fallacy in an argument such as the one that Wreen is giving. (shrink)

In 1929, Wittgenstein reconsidered the vexing color-Incompatibility problem: explaining how and why more than one color cannot be at a single time and place. He continued discussing the problem in 1930 and later. He offered solutions in the "tractatus", In 1929 and in 1930. Are the solutions the same? clearly not, Because the 1929 solution differs from his earlier one. However, I argue that the 1930 solution is substantially identical with that of 1929 and that the 1929-30 solution is continuous (...) with the "tractatus" as well as some later doctrines. Therefore 1929-30 marks a period of intellectual ferment rather than massive abandonment of his earlier views. (shrink)

Logic as a subject has existed for a long time. Aristotle and the Stoics identified some of its principles, as did Indian logicians. And this ancient logic underwent an extraordinary mathematical development in the last hundred and fifty years. So logic certainly exists, at least as a branch of mathematics. The question is whether it is anything more than that.

From his earliest work in The Structure of Behavior, Maurice Merleau-Ponty abrogates accounts of organic form that posit the organism as either passively ordered by the environment which precedes it, or as actively constituting its environment. I argue that Merleau-Ponty first develops what I term a genetic concept of form, in which the organism-environment relationship unfolds developmentally. This account of genetic form, however, requires a further concept of generative form to overcome the conceptual distinction between constituting activity and constituted passivity. (...) I contend that rather than pre-existing its own development ideally, in a genetic or developmental blueprint, or environmentally, in given causes, that instead form emerges expressively and dynamically. To develop the concept of generative form I turn to Merleau-Ponty’s lecture courses Institution and Nature, while drawing from examples in animal motorperceptual development and inter-bodily communication. In doing so, I contend that this idea of generativity requires for us to think of organisms as passive, though not as passively constituted by a nature in-itself, but rather as passively instituted by a natural sense that orients the possibilities of organic development without itself existing asan already realized form of life. I argue that the notion of generative form offers an approach to thinking of species differences not as essential differences in kind, but as elaborations of a natural generativity that precedes and grounds individual animate forms.

Review of Avner Baz: When Words Are Called For: A Defense of Ordinary Language Philosophy , Cambridge, Mass.: Harvard University Press, 2012.

Food insecurity and the loss of soil nutrients and productive capacity in Africa are serious problems in light of the rapidly growing African population. In semi-arid central Tanzania currently practiced traditional crop production systems are no longer adaptive. Organic crop production methods alone, while having the capacity to enable food security, are not feasible for these small-scale farmers because of the extra land, skill, resources, and 5–7 years needed to benefit from them—particularly for maize. Maize, grown by 94 % of (...) farmers, has substantial nitrogen needs. The most practical ways of satisfying maize nutrient needs is via integrated soil fertility management, a combination of organic and Green Revolution methods. Maize has been shown in research to outyield the indigenous crops millet and sorghum in nearly all situations including drought. Conservation Agriculture (CA) in Africa has two main categories—organic and herbicide-mediated. The organic version of CA, despite years of promotion, has had a low rate of adoption. Herbicide-mediated zero tillage CA via backpack sprayer can substantially increase conventional maize yields while at the same time nearly eliminating erosion and increasing rainwater capture up to fivefold. Glyphosate herbicide is a non-proprietary product produced in Africa and approved for small farm use. The systemic nature of glyphosate allows the killing of perennial grasses that would otherwise need deep plowing to kill. The rooted weed residues protect the soil from erosion. The risks of glyphosate use are substantially outweighed by the benefits of increased food security and crop system sustainability. (shrink)

The social sciences stand at a strange crossroads. There is a greater need for disciplined inquiry into the issues of policy facing the United States. Yet the incentives in the political system, and in the professional guilds of those performing social research, discourage a close involvement of many prominent social scientists with policy. The political system, fearing an elite imposing its values on society, welcomes the natural scientist who seems to conform to the model of the politically neutral expert who (...) solves problems and addresses “facts”. This model also fits the higher ranks of the civil service, made up of specialists rather than generalist administrators, and the outside advisers serving officials concerned with high policy. Likewise, to protect themselves from changes of partisanship, leading academic social scientists forsake policy concerns for topics within the analytic traditions of Weberian Wertfreiheit. Just as Weber sought to avoid censorship by value neutral scholarship, the modern social scientist disdains the normative concerns of policy in favour of more tractable, morally neutral issues defined as the core of the discipline.The country needs to draw some of the best analytical talent in the social science community into the policy process and advisory roles. Disciplined inquiry cannot be left only to technicians whose professional interests are far removed from political, economic, social and other human sciences. To promote better policy and better social science, we should encourage serious, professionally grounded inquiry into social values, the directions of policy, and the role and proper limits of state power. In the clamour of American politics, there is little danger that policy will be monopolised by an elite group, but considerable danger that debate on policy will be impoverished by the absence of those most knowledgeable about social and economic reality.

Bentley et al. say that economics is the science of their map's northwest quadrant, where choice is individual and transparent. This accepts the picture of the discipline common among behavioral economists who aim to drag economics southward but not eastward. In fact, leading economics journals regularly publish models located in all four quadrants, and the prominence of work from the eastern zone is increasing.

In a 1998 Hume Studies book symposium, Peter Millican provided excellent critical comments on my Cognition and Commitment in Hume’s Philosophy, and I am grateful that he has done the same for Hume. Many of the new or revised interpretations in the latter book result, directly or indirectly, from his extraordinary stimulus, both in his writings and in person, as a philosophical scholar and interlocutor. His comments range over much of the book, but the majority of them concern chapter 2, (...) chapter 3, chapter 4, and chapter 8 (“Morality... (shrink)
