When, if ever, is one justified in accepting the premises of an argument? What is the proper criterion of premise acceptability? Can the criterion be theoretically or philosophically justified? This is the first book to provide a comprehensive theory of premise acceptability and it answers the questions above from an epistemological approach that the author calls common sense foundationalism. It will be eagerly sought out not just by specialists in informal logic, critical thinking, and argumentation theory but also by a (...) broader range of philosophers and those teaching rhetoric.

Among the more significant developments of the twentieth century, the widespread attention given to 'rights issues' must surely justify ranking it somewhere near the top. Never before has the issue of rights attracted such a wide audience or stirred so much controversy. Until very recently 'rights' were traditionally recognized as attributable only to humans. Today, we increasingly are hearing a call to extend 'rights' to the nonhuman animal and, on occasion, to the environment. In this book, James B. Reichmann, (...) S.J., undertakes an investigation of the metaethical grounds of 'rights' theory, with special focus on the controversial issue of whether creatures other than humans can and should be considered true subjects of 'rights.' He contends that before assigning rights to this or that individual or group, whether human or not, we need to be very clear about what it is we are assigning, to whom, and why. The book argues forcefully that the various recent efforts to build a case supporting animal and environmental 'rights' fail in their quest, and that any such effort resting on a Darwinian evolutionary base is likewise condemned to fail. In furtherance of this claim the author first investigates life phenomena, followed by a detailed comparative study of knowing, communicating and doing, as these are observed in the human and the nonhuman animal. This in turn is followed by an overview of diverse views advanced by contemporary environmental ethicists and animal 'rights' advocates, including Peter Singer, Tom Regan, J. Baird Callicott, Laura Westra, and Don E. Marietta, Jr. Representative though doubtless provocative conclusions drawn from this study include the claims that: (1) Classic Darwinian theory provides no admissable premise from which to derive a theory of inherent, inalienable rights. (2) No satisfactory explanation of the origin of rights and obligation can derive save from within the context of natural law theory. (3) The human person alone unqualifiedly possesses rights. (4) The view that vegetarianism is an ethical mandate is neither compatible with the Christian world view, nor philosophically sound. ABOUT THE AUTHOR: James B. Reichmann, S.J., is professor emeritus of philosophy at Seattle University where he continues to teach. (shrink)

We perceive relevance by virtue of inference habits, which may be expressed as Pierce's leading principles or as Toulmin's warrants. Hence relevance in a descriptive sense is a ternary relation between two statements and a set of inference rules. For a normative sense, the warrants must be properly backed. Different types of warrant to empirical generalizations, we introduce L.J. Cohen's notion of inductive support. A to empirical generalizations, we introduce L.J. Cohen's notion of inductive support. A generalization H is supported (...) by evidence E to degree i/in iff E indicates that H passes canonical test i, where there are n canonical tests. In a canonical test, one or more relevant variables, factors which may falsify H, are varied. H passes a test if it is not falsified. The tests are cumulative. Degree of support is relative to the canonical test, and may be modeled as relative to a point in a dialectical situation. A value of a variable at which H is falsified is a rebutting value. A is normatively relevant to B with respect to W iff sup[associated generalization(W), E] = i/n and for j > i, there is a presumption that the values of j are non-rebuting. (shrink)

Relevance of premises to conclusion can be explicated through Toulmin’s notion of warrant, understood as an inference rule, albeit not necessarily formal. A normative notion of relevance requires the warrant to be reliable. To determine reliability, we propose a fourfold classification of warrants into a priori, empirical, institutional, and evaluative, with further subdivisions possible. This classification has its ancestry in classical rhetoric and recent epistemology. Distinctive to each type of warrant is the mode by which such connections are intuitively discovered (...) and the grounds on which we ultimately justify them. The classification of warrants is thus epistemic. We illustrate the difference by contrasting empirical physical with institutional intuition, and argue for the advantages of this approach over Toulmin’s conception of field dependence. (shrink)

In this paper I argue that selective abortion for disability often involves inadequate counselling on the part of reproductive medicine professionals who advise prospective parents. I claim that prenatal disability clinicians often fail in intellectual duty—they are culpably ignorant about intellectual disability. First, I explain why a standard motivation for selective abortion is flawed. Second, I summarize recent research on parent experience with prenatal professionals. Third, I outline the notions of epistemic excellence and deficiency. Fourth, I defend culpable ignorance as (...) the best explanation of inadequate disability counselling. Fifth, I rebut alternative explanations. My focus is pregnancies diagnosed with mild or moderate intellectual disability. (shrink)

Our typology is based on two ground adequacy factors, one logical and one epistemic. Logically, the step from premises to conclusion may be conclusive or only ceteris paribus. Epistemically, warrants may be backed a priori or a posteriori. Hence there are four types of arguments: conclusive a priori, defeasible a priori, defeasible a posteriori, and prima facie conclusive a posteriori. We shall give an example of each and compare our scheme with other typologies.

The most striking observable feature of our indeterministic quantum universe is the wide range of time, place, and scale on which the deterministic laws of classical physics hold to an excellent approximation. This essay describes how this domain of classical predictability of every day experience emerges from a quantum theory of the universe’s state and dynamics.

A key question in disability studies, philosophy, and bioethics concerns the relationship between disability and well-being. The mere difference view, endorsed by Elizabeth Barnes, claims that physical and sensory disabilities by themselves do not make a person worse off overall—any negative impacts on welfare are due to social injustice. This article argues that Barnes’s Value Neutral Model does not extend to intellectual disability. Intellectual disability is (1) intrinsically bad—by itself it makes a person worse off, apart from a non-accommodating environment; (...) (2) universally bad—it lowers quality of life for every intellectually disabled person; and (3) globally bad—it reduces a person’s overall well-being. While people with intellectual disabilities are functionally disadvantaged, this does not imply that they are morally inferior—lower quality of life does not mean lesser moral status. No clinical implications concerning disability-based selective abortion, denial of life-saving treatment, or rationing of scarce resources follow from the claim that intellectual disability is bad difference.

The Covid-19 pandemic provides a real-world context for evaluating the fairness of disability-based rationing of scarce medical resources. I discuss three situations clinicians may face: rationing based on disability itself; rationing based on inevitable disability-related comorbidities; and rationing based on preventable disability-related comorbidities. I defend three conclusions. First, in a just distribution, extraneous factors do not influence a person’s share. This rules out rationing based on disability alone, where no comorbidities decrease a person’s capacity to benefit from treatment. Second, in (...) a just distribution, undeserved luck does not influence a person’s share. This rules out rationing for biologically caused comorbidities that decrease capacity to benefit. Third, in a just distribution, social injustice does not influence a person’s share. This rules out rationing for socially caused comorbidities that decrease capacity to benefit. (shrink)

In describing his seven and a half years as a prisoner of war in North Vietnam, the late Vice Admiral James B. Stockdale has said: "In that atmosphere of death and hopelessness, stripped of the niceties, the amenities of civilization, my ideas on life and leadership crystallized." Despite torture, intimidation, and isolation, Stockdale fulfilled his duties as senior officer among the prisoners with intelligence and courage, defining rules of conduct and maintaining morale. He often described the intense pressures of (...) that situation as a "melting" experience, in which preconceived feelings, fears, and bias melt as one comes to realize that, under the gun, you must grow or fail—or, in some cases, grow or die. This collection of his essays and speeches from the 1980s and 1990s reinforces how that experience formed a lifelong basis for his philosophical thought on issues of character, leadership, integrity, personal and public virtue, and ethics. The selections in this volume all reflect, in one way or another, a central theme: how man can rise with dignity to prevail in the face of adversity. (shrink)

This paper draws from the turnover and emotions literatures to explore how job embeddedness, in the context of abusive supervision, can impact job frustration, citizenship withdrawal, and employee deviance. Results indicate that employees with abusive supervisors were more likely to be frustrated with their jobs and engage in more deviance behaviors. And yet, the relationship between abusive supervision and job frustration was moderated by job embeddedness such that the relationship was weaker and negative for those higher in job embeddedness and (...) stronger and positive for those lower in job embeddedness. In other words, contrary to our original predictions, individuals who were more embedded in their jobs with an abusive supervisor were actually less likely to experience job frustration or engage deviance behaviors. Important implications for management research and practice are discussed. (shrink)

In this article, we explore the tension between truth telling and the demands of civic life, with an emphasis on the tension between serving one's country and reporting the truth as completely and independently as possible. We argue that the principle of truth telling in journalism takes priority over the promotion of civic values, including a narrow patriotism. Even in times of war, responsible journalism must not allow a narrow patriotism to undermine its commitment to truth telling. Journalists best fulfill (...) their civic role by adopting the perspective of a democratic patriotism. We conclude that if news organizations accept the primacy of truth telling and democratic patriotism, they should not embed reporters with military units, or if they do, they have an ethical obligation to implement special editorial precautions.

This paper takes up an underdeveloped argument of Charles Taylor that linguisticality is constitutive of moral agency. Taylor’s position is part of a set of contemporary arguments that language, especially as dialogue or discourse, is the normative framework which grounds or validates fundamental norms or values. Taylor’s contribution to this “dialogical turn” is substantial and innovative, but it is not without weakness. Rather than deal with all the issues involved in this dialogical turn, I argue just that language does ground (...) morality as a distinctively human way of creating meaning, that is, as Taylor argues, constitutive of the self and self-understanding. Self-understanding, or the appropriation of moral self-consciousness, is what is meant by the authenticity and autonomy which constitute moral authority. I argue in essence that language provides a necessary and constitutive link between private and public spheres of meaning in a way that renders moral discourse meaningful and constitutively human.

As a concept, affordance is integral to scholarly analysis across multiple fields—including media studies, science and technology studies, communication studies, ecological psychology, and design studies among others. Critics, however, rightly point to the following shortcomings: definitional confusion, a false binary in which artifacts either afford or do not, and failure to account for diverse subject-artifact relations. Addressing these critiques, this article demarcates the mechanisms of affordance—as artifacts request, demand, allow, encourage, discourage, and refuse—which take shape through interrelated conditions: perception, dexterity, (...) and cultural and institutional legitimacy. Together, the mechanisms and conditions constitute a dynamic and structurally situated model that addresses how artifacts afford, for whom and under what circumstances. (shrink)

Where Men Hide is a spirited tour of the dark and often dirty places men go to find comfort, camaraderie, relaxation, and escape. Ken Ross's striking photographs and James B. Twitchell's lively analysis trace the evolution of these virtual caves, and question why they are rapidly disappearing. They find that for centuries men have met with each other in underground lairs and clubhouses to conduct business or to bond and indulge in shady entertainments. In these secret dens, certain rules (...) are abandoned while others are obeyed. Twitchell connects the places men hide with figures like Hemingway and Huck Finn, Frederick Jackson Turner's theory of the American frontier, and the mythological interpretations of Joseph Campbell and Robert Bly. Documenting both traditional and contemporary male haunts, Twitchell and Ross examine the provenance, purpose, and appeal of this little-discussed and controversial phenomenon. (shrink)

The specification of specific and often unique fates to individual cells as a function of their position within a developing organism is a fundamental process during the development of multicellular organisms. The development of the Drosophila embryonic central nervous system serves as an excellent model system in which to clarify the developmental mechanisms that link pattern formation to cell-type specification. The Drosophila embryonic central nervous system develops from a set of neural stem cells termed neuroblasts. Neuroblasts arise from the ectoderm (...) in an invariant pattern, and each neuroblast acquires a unique fate based on its position within this pattern. Two groups of genes recently have been demonstrated to govern the individual fate specification of neuroblasts. One group, the segment polarity genes, enables neuroblasts that develop in different anteroposterior positions to acquire different fates. The second group, referred to as the columnar genes, ensures that neuroblasts that develop in different dorsoventral domains assume different fates. When integrated, the activities of the segment polarity and columnar genes create a Cartesian coordinate system that bestows unique fates to individual neuroblasts as a function of their position of formation within the ectoderm.

College courses are often disconnected both from other disciplines and from student’s lives. When classes are taught in isolation from each other students experience them as unrelated fragments. In addition, college courses often lack personal meaning and relevance. Interdisciplinary learning communities—classes in which the subject matters of two or more fields are integrated—can help overcome these two problems by providing an education that is holistic and coherent. In this paper I report on how philosophy courses can be blended with English (...) classes and how theoretical perspectives can be connected to student’s personal lives. (shrink)

Is truth a condition of premise adequacy? We may distinguish objective and subjective argument correctness. Objective correctness means true premises rendering the conclusion true or probable. Subjective correctness means acceptable pr emises rendering the conclusion acceptable. Acceptability depends on evidence available and so is internalist. Objective and subjective correctness of the premises is ordinarily distinct. For connection adequacy, objective rightness and subjective righ tness coincide. We recognize entailment or rendering probably a priori. Logic is thus internalist. Logic needs an internalist (...) notion of acceptability for premise evaluation to fall within its purview, although it need not deny the objective sens e of rightness. (shrink)

This study examined whether scaffolded lesson study might contribute to the emergence of a shared professional teaching knowledge culture among 4th grade social studies teachers. The study reports findings from a three-year lesson study professional development project that sought to develop professional teaching knowledge for problem-based historical inquiry among participating teachers. Participants included six 4th grade State History teachers from three different schools and three different school systems. Using qualitative data collected during three yearlong lesson study cycles, we present evidence (...) that suggests that lesson study can be used to develop a shared professional teaching knowledge culture among 4th grade social studies teachers. We suggest, however, that a combination of factors might contribute to variations in teachers' participation in that shared professional teaching knowledge culture including the degree to which the teachers embraced the public nature of lesson study. These factors include the teachers' idiosyncratic views of teaching and learning, the teachers' individual tolerance for socially constructing curricula, and the degree to which teachers acceded to cultural obstacles within elementary schooling.
