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)

Chapter The Need for a Theory of Argument Structure. THE STANDARD APPROACH The approach to argument diagramming which we call standard was originated, ...

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.

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.

Premise acceptability is conceptually connected to presumption. To say that a premise is acceptable just when there is a presumption in its favor is to give a first approximation to this connection. A number of popular principles of presumption suggest that whether there is a presumption for a premise, belief, or claim depends on the sources which vouch for it. Sources consist of internal belief-generating mechanisms and external testimony. Alvin Plantinga's notion of warrant lays down four conditions upon a source (...) for the belief which it generates to be warranted. We argue that there is a presumption for a premise, belief, or claim if and only if there is a presumption of warrant for that premise,belief or claim. This amounts to the thesis that there is a presumption for a belief from a challenger's point of view if and only if there is a presumption from that person's point of view that her cognitive faculties which have generated the belief have been functioning properly, in an appropriate cognitive environment, in accord with a segment of her design plan aimed at the truth, and that these faculties are reliable. In light of our argument for this thesis, we may legitimately claim that one way to determine that there is a presumption for a belief is to determine that there is a presumption of warrant for that belief, and thus that in determining whether there is a presumption for a belief or premise, we may consider the source.

FRANCISCO SUÁREZ, THE GREAT JESUIT PHILOSOPHER AND THEOLOGIAN, has long been recognized as a pivotal figure in the development of Western philosophy. His thought is heavily indebted to the medieval philosophical tradition but also bears striking intimations of key themes in modern thought. In this paper I address one of the most controversial questions related to the thought of Suárez, namely, his relationship to the nominalist tradition. However, I shall do so rather indirectly by focusing not on explicit metaphysical questions (...) but rather on his account of our acquisition of universal concepts and its foundation in reality. By placing questions about the knowledge of singular and universal at the center of the discussion, I hope to shed new light on his account of the objectivity that we can have in our knowledge.

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)

Medieval philosophy is the collective name given to the philosophies of thinkers who lived between the end of the Roman Empire, c. 400, and the beginning of the modern era, c. 1490. The philosophers profiled in DLB Volume 115 were involved in education, public life and ecclesiastical administration, and thus represent the various schools of thought that existed throughout this vast period. This volume offers much new information on these scholars, and fills the gap in available literature. The entries, containing (...) biographies, bibliographies and beliefs of the philosophers, reflect the most recent developments in the field. (shrink)

Because the mind is the significance of the brain and God is the significance of the mind, the concept “mind” bridges how the brain works and traditional patterns of belief. The left mind, which utilizes rational vigilance and the imperative instructions of proclamation, names and analyzes the urgently right. The right mind, which discloses the relational responsiveness of numinous presence and natural symbolism, is immersed in and integrates the ultimately real. Together they provide a typology of mind‐states with which to (...) assess regressive, functional, and creative patterns. Hand dominance, gender differences, and cultural bias qualify the use of the metaphor. (shrink)

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.

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)

As human beings we inevitably try to explain our experience. In philosophical language, we deal with transcendent assertions and aspirations. The issue, then, is: how can we talk about what matters, given the structures inherent in language and basic to the way we are made? Instead of the philosophical category of Being, I advance a case for giving the human brain privileged status as an analogical expression of God, the symbol‐concept of what matters most, and then suggest the illumination which (...) can come with using that analogical expression, especially as that analogy connects us with the environment at the limbic level and constructs our world at the cerebral level.

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)

. The human brain combines empathy and imagination via the old brain which sets our destiny in the evolutionary scheme of things. This new understanding of cognition is an emergent phenomenon—basically an expressive ordering of reality as part of “a single natural system.” The holographic and subsymbolic paradigms suggest that we live in a contextual universe, one which we create and yet one in which we are required to adapt. The inadequacy of the new brain—specially the left hemisphere's rational view (...) of destiny—is replaced by a view of a new relatedness in reality in which human destiny comes from and depends upon the mutual interchange between the new brain and the old brain for the survival of what is significant to the whole systemic context in which we live.

This study examined how sales managers react to ethical and unethical acts by their salespeople. Deontological considerations and, to a much lesser extent, teleological considerations predicted sales managers' ethical judgments. Sales managers' intentions to reward or discipline ethical or unethical sales force behavior were primarily determined by their ethical judgments. An organization's perceived ethical work climate was not a significant predictor of sales managers' intentions to intervene when ethical and unethical sales force behavior was encountered.

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)

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)

This article examines the occurrence of the phrase dharmaparyāyo hastagato, “having the enumeration of the teaching in one’s hand,” in a select number of texts classified as Mahāyāna sūtras and theorizes its occurrence in relation to the use of the book in the religious cultures of middle period Indian Mahāyāna Buddhism. In recent scholarly discourse, the “cult of the book” in Mahāyāna Buddhist formations has been hypothesized to occur in relation to shrines or not even to have occurred at all. (...) This article suggests an alternative hypothesis. The paper first analyzes the syntax and composition of the terms dharmaparyāya and the participle hastagata as well as their occurrences within Indian Buddhist literature in Indic languages and in Tibetan and Chinese translations. The paper then identifies the occurrence of the phrase dharmaparyāyo hastagato in a select number of Mahāyāna sūtras and relates this phrase to an observable gradual process of bibliofication, a process where texts increasingly reference themselves as protective objects, that is detectable in the layers of accretion found within the comparative analysis of extant manuscripts. Based on this analysis, the paper concludes that the “cult of the book,” rather than being a stable or local cult phenomena, was comprised of highly mobile and translocal textual communities who carried their object of veneration with them.

From beginning to end, the poem is literally made up of relations…[that] constitute a method of contemplation and criticism, a way of inviting the reader to think in terms of one thing in terms of another. Consider, for example, Odysseus' trip to Chryse in book 1, a passage I never read without surprise: in this tense and heavily charged world, in which everything seems to have been put into potentially violent contention, why are we given this slow and deliberate journey, (...) so heavily formulaic in texture? The answer is that this is a ritual of reconciliation, a kind of healing, which will receive its most ample performance at the great movement in book 24 when Achilles and Priam share their sorrows. A movement begins here that will run throughout the poem.It is by such an art of arrangement, by placing one thing against another, that Homer criticizes the world of book 1 with which he began; not, as we expect of a writer today, by elaborating competitive languages of motives and value but by ordering his materials into patterns of experience that teach the reader something different from anything the material itself seems to say.1 In a way the poem, as a whole thus has the form of argument; not, of course, argument in the ratiocinative sense of a thesis supported by propositions, from which it can be said to proceed by the rules of logic or the laws of probability, but argument as an activity of critical engagement, a definition of resources and a testing of limits, that results in the creation of a new position taken by the writer and offered to the reader. An argument goes on in the text, but its method is closer to that of music than debate.· 1. Cf. Cedric H.

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.

The human experience of meaning‐making lies at the roots of consciousness, creativity, and religious faith. It arises from the basic experience of separation from a loved object, suffered by all mammals, and, in general terms, from the experienced gap between ourselves and our environment. We fill the gap with transitional objects and symbols that reassure us of basic continuity in ourselves and in the world. These objects and symbols also serve the neurognostic function of demonstrating what the world is like. (...) Thus, humanity lives by faith, as manifested in its pattern‐making capacity, and not by literal sight. (shrink)

In advocating that we extend our experiment in political democracy in America to include economic democracy as well, the Bishops' Letter assumes the basic social nature of man. This leaves an enormous gap between the values and attitudes they recommend and the private and individualistic view of man that undergirds our traditional economic thinking. This essay attempts to bridge that gap in terms of a theory of practice, individual in emphasis, but bringing out the enabling conditions of any and all (...) practice without which practice would not be possible. It is suggested that these presuppositions of practice function normatively in all practice, economic as well as other types, and ought to be of interest to the practice of any adequately self-interested individual. They constitute a large part of what we used to call the "public interest". (shrink)

In a priori analogies, the analogue is constructed in imagination, sharing certain properties with the primary subject. The analogue has some further property clearly consequent on those shared properties. Ceteris paribus the primary subject has that property also. The warrant involves non-empirical, e.g., moral intuition but is also defeasible. The argument is thus neither deductive nor inductive, but an additional type. In an inductive analogy, the analogues back the warrant from below. Distinguishing these two types of arguments by analogy gives (...) epistemic evaluative factors primacy over resemblance factors in classifying arguments—a prescient insight on Govier’s part.

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.

Logical Form, Probability Interpretations, and the Inductive/Deductive Distinction.

Many in the informal logic tradition distinguish convergent from linked argument structure. The pragma-dialectical tradition distinguishes multiple from co-ordinatively compound argumentation. Although these two distinctions may appear to coincide, constituting only a terminological difference, we argue that they are distinct, indeed expressing different disciplinary perspectives on argumentation. From a logical point of view, where the primary evaluative issue concerns sufficient strength of support, the unit of analysis is the individual argument, the particular premises put forward to support a given conclusion. (...) Structure is internal to this unit. From a dialectical point of view, where the focus concerns how well a critical discussion comes to a reasoned conclusion of some disputed question, the argumentation need not constitute a single unit of argument. The unit of dialectical analysis will be the entire argumentation made up of these several arguments. The multiple/co-ordinatively compound distinction is dialectical, while the linked/convergent distinction is logical. Keeping these two pairs of distinctions separate allows us to see certain attempts to characterize convergent versus linked arguments as rather characterizing multiple versus co-ordinatively compound arguments, in particular attempts of Thomas, Nolt, and Yanal, and to resolve straightforwardly conflicts, tensions, or anomalies in their accounts. Walton's preferred Suspension/Insufficient Proof test to identify linked argument structure correctly identifies co-ordinatively compound structure. His objection to using the concept of relevance to explicate the distinction between linked and convergent structure within co-ordinatively compound argumentation can be met through explicating relevance in terms of inference licenses. His counterexample to the Suspension/No Support test for identifying linked structure which this approach supports can itself be straightforwardly dealt with when the test is explicated through inference licenses.

Building on the work of Sproule, Fahnestock and Secor, and Kruger, we present a specific typology of statements. In particular, we distinguish broadly logically determinate statements, descriptions, interpretations, and evaluations. We generate this typology through a series of dichotomous divisions of statements. We divide statements first into the broadly logically determinate versus contingent, the contingent into the evaluational versus natural, and the natural into the extensional versus intensional. We show that the rationales for these distinctions are well motivated and philosophically (...) important. In particular, we argue that identifying the type of a statement is relevant to showing whether or not the sources vouching for it render the statement epistemically acceptable. (shrink)

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)

The development of vertebrate and invertebrate nervous systems requires the production of thousands to millions of uniquely specified neurons from progenitor neural stem cells. A central question focuses on the elucidation of the developmental mechanisms that function within neural stem cell lineages to impart unique identities to neurons. A recent report(1) details the roles that two genes, pdm‐1 and pdm‐2, play within an identified neural stem cell lineage in the Drosophila embryonic central nervous system. The results show that pdm‐1 and (...) pdm‐2 are coexpressed in an identified neural precursor and function redundantly to specify the fate of this cell. As such this report offers an initial view of the genetic programs that create neural diversity. (shrink)
