(2013). Hierarchical Bayesian models as formal models of causal reasoning. Argument & Computation: Vol. 4, Formal Models of Reasoning in Cognitive Psychology, pp. 36-45. doi: 10.1080/19462166.2012.700321.

Hierarchical cognitive mechanisms underlie sophisticated behaviors, including language, music, mathematics, tool-use, and theory of mind. The origins of hierarchical logical reasoning have long been, and continue to be, an important puzzle for cognitive science. Prior approaches to hierarchical logical reasoning have often failed to distinguish between observable hierarchical behavior and unobservable hierarchical cognitive mechanisms. Furthermore, past research has been largely methodologically restricted to passive recognition tasks as compared to active generation tasks that are (...) stronger tests of hierarchical rules. We argue that it is necessary to implement learning studies in humans, non-human species, and machines that are analyzed with formal models comparing the contribution of different cognitive mechanisms implicated in the generation of hierarchical behavior. These studies are critical to advance theories in the domains of recursion, rule-learning, symbolic reasoning, and the potentially uniquely human cognitive origins of hierarchical logical reasoning.

Empirical evidence has demonstrated the validity and reliability of moral development instruments such as the Defining Issues Test (DIT) and Moral Judgment Test (MJT). Rasch item reliability for each was .95. A newer instrument generated using the Model of Hierarchical Complexity had item reliability of .97. Rasch scores of responses to each instruments' items correlated well with the items' measure of hierarchical complexity, r = .286, .372, .557, .767. Test items used to measure moral reasoning were significantly (...) correlated. In general, stage of moral development did not predict political affiliation or voting, supporting Kohlberg's claim that structure, not content, underlies stage. (shrink)

Recent research in cognitive and computational neuroscience portrays the neocortex as a hierarchically structured prediction machine. Several theorists have drawn on this research to challenge the traditional distinction between perception and cognition – specifically, to challenge the very idea that perception and cognition constitute useful kinds from the perspective of cognitive neuroscience. In place of this traditional taxonomy, such theorists advocate a unified inferential hierarchy subject to substantial bi-directional message passing. I outline the nature of this challenge and then raise (...) two objections to the cognitive architecture it proposes as a replacement: first, standard ways of characterising this inferential hierarchy are in tension with the representational reach of conceptual thought; second, there is compelling evidence that commonsense reasoning is structured around highly domain-specific intuitive theories that are difficult to situate within a single hierarchy.

Leader-managers face a myriad of competing values when they engage in ethical decision-making. Few studies help us understand why certain reasons for action are justified, taking precedence over others when people choose to respond to an ethical dilemma. To help address this matter we began with a qualitative approach to disclose leader-managers' moral motives when they decide to address a work-related ethical dilemma. One hundred and nine military officers were asked to provide their reasons for taking action, justifications of their (...) reasons, and to explain these justifications. We used network analysis techniques to identify a hierarchical motive structure. The motive structure is a cognitive map that identifies ethical motives and perceptions of how these ethical motives relate to each other. The motives identified represent classic conceptualizations of moral behavior; namely, virtue theories, consequentialism, and deontological theories, along with another category that expressed the emotional significance of the moral judgment, which we refer to as emotional empiricism.

Metaphysicians, ethical theorists and philosophers of law squabble endlessly about what it is for a person to act — or perhaps even to ‘will’ — more or less freely. A vital issue in this controversy is how we should analyse two obvious but surprisingly problematical contrasts. The first antithesis is between things we do because we are forced, and deeds we perform because we want to — sometimes after having discovered preponderant reasons in their favour. The other polarity is more (...) general. In most situations, if I act on my desire, I act more freely than if I had not had the desire. But what if my attitude is the product of childhood conditioning — or later brainwashing, brain surgery, hypnosis, behaviour modification, alcoholisim, narcotics addiction, neurosis, psychosis or worse? Then isn't my autonomy diminished? What is it about these latter desires, or their origin, that differentiates them from their unthreatening congeners? (shrink)

The debate over whether or not economics is value-free has focused on the fact-value distinction: “is” does not imply “ought.” This paper approaches the role of ethics in economics from a Thomistic perspective, focusing not on the content of economic analysis, but on the actions taken by economic researchers. Positive economics, when it satisfies Aristotle's definition of technique, enjoys a certain autonomy from ethics, an autonomy limited by a technique's dependence for guidance and justification on ethical reflection. The modern isolation (...) of technique from ultimate ends entails the risk of mistaking the proximate ends of economics for ultimate ends, especially when applying economic methods in new ways or to new social phenomena.

The modern view of logical reasoning as modeled by a consequence operator has allowed for huge developments in the study of logic as an abstract discipline. Still, it is unable to explain why it is often the case that the same designation is used, in an ambiguous way, to describe several distinct modes of reasoning over the same logical language. A paradigmatic example of such a situation is ‘modal logic’, a terminology which can encompass reasoning over Kripke (...) frames, but also over Kripke models, and in any case either locally or globally . Herein, we adopt a novel abstract notion of logic presented as a lattice-structured hierarchy of consequence operators, and explore some common proof-theoretic and model-theoretic ways of presenting such hierarchies through a collection of meaningful examples. In order to illustrate the usefulness of the notion of hierarchical consequence operators we address a few questions in the theory of combined logics, where a suitable abstract presentation of the logics being combined is absolutely essential. We show how to define the operation, in general, and we achieve a number of interesting preservation results for fibring within the context of 2-hierarchies. (shrink)

This article discusses the proof theory, semantics and meta-theory of a class of adaptive logics, called hierarchic adaptive logics. Their specific characteristics are illustrated throughout the article with the use of one exemplary logic HKx, an explicans for reasoning with prioritized belief bases. A generic proof theory for these systems is defined, together with a less complex proof theory for a subclass of them. Soundness and a restricted form of completeness are established with respect to a non-redundant semantics. It (...) is shown that all hierarchic adaptive logics are reflexive, have the strong reassurance property and that a subclass of them is a fixed point for a broad class of premise sets. Finally, they are compared to a different yet related class of adaptive logics. (shrink)

There is an apparent dilemma for hierarchical accounts of propositions, raised by Bruno Whittle : either such accounts do not offer adequate treatment of connectives and quantifiers, or they eviscerate the logic. I discuss what a plausible hierarchical conception of propositions might amount to, and show that on that conception, Whittle’s dilemma is not compelling. Thus, there are good reasons why proponents of hierarchical accounts of propositions did not see the difficulty Whittle raises.

We present a completeness proof for Propositional Interval Temporal Logic with finite time which avoids certain difficulties of conventional methods. It is more gradated than previous efforts since we progressively reduce reasoning within the original logic to simpler reasoning in sublogics. Furthermore, our approach benefits from being less constructive since it is able to invoke certain theorems about regular languages over finite words without the need to explicitly describe the associated intricate proofs. A modified version of regular expressions (...) called Fusion Expressions is used as part of an intermediate logic called Fusion Logic. Both have the same expressiveness as PITL but are lower-level notations which play an important role in the hierarchical structure of the overall completeness proof. In particular, showing completeness for PITL is reduced to showing completeness for Fusion Logic. This in turn is shown to hold relative to completeness for conventional linear-time temporal logic with finite time. Logics based on regular languages over finite words and!-words offer a promising but elusive framework for formal specification and verification. A number of such logics and decision procedures have been proposed. In addition, various researchers have obtained complete axiom systems by embedding and expressing the decision procedures directly within the logics. The work described here contributes to this topic by showing how to exploit some interesting links between regular languages and interval-based temporal logics. (shrink)

Given the pervasiveness of gene sharing in evolution and the extent of homology across the tree of life, why is everything not homologous with everything else? The continuity and overlapping genetic contributions to diverse traits across lineages seem to imply that no discrete determination of homology is possible. Although some argue that the widespread overlap in parts and processes should be acknowledged as “partial” homology, this threatens a broad base of presumed comparative morphological knowledge accepted by most biologists. Following a (...) long scientific tradition, we advocate a strategy of “theoretical articulation” that introduces further distinctions to existing concepts to produce increased contrastive resolution among the labels used to represent biological phenomena. We pursue this strategy by drawing on successful patterns of reasoning from serial homology at the level of gene sequences to generate an enriched characterization of serial homology as a hierarchical, phylogenetic concept. Specifically, we propose that the concept of serial homology should be applied primarily to repeated but developmentally individualized body parts, such as cell types, differentiated body segments, or epidermal appendages. For these characters, a phylogenetic history can be reconstructed, similar to families of paralogous genes, endowing the notion of serial homology with a hierarchical, phylogenetic interpretation. On this basis, we propose a five-fold theoretical classification that permits a more fine-grained mapping of diverse trait-types. This facilitates answering the question of why everything is not homologous with everything else, as well as how novelty is possible given that any new character possesses evolutionary precursors. We illustrate the fecundity of our account by reference to debates over insect wing serial homologs and vertebrate paired appendages. (shrink)

Two controversies exist regarding the appropriate characterization of hierarchical and adaptive evolution in natural populations. In biology, there is the Wright-Fisher controversy over the relative roles of random genetic drift, natural selection, population structure, and interdemic selection in adaptive evolution begun by Sewall Wright and Ronald Aylmer Fisher. There is also the Units of Selection debate, spanning both the biological and the philosophical literature and including the impassioned group-selection debate. Why do these two discourses exist separately, and interact relatively (...) little? We postulate that the reason for this schism can be found in the differing focus of each controversy, a deep difference itself determined by distinct general styles of scientific research guiding each discourse. That is, the Wright-Fisher debate focuses on adaptive process, and tends to be instructed by the mathematical modeling style, while the focus of the Units of Selection controversy is adaptive product, and is typically guided by the function style. The differences between the two discourses can be usefully tracked by examining their interpretations of two contested strategies for theorizing hierarchical selection: horizontal and vertical averaging.

Certain recurring themes have emerged from research on intelligent behavior from literatures as diverse as developmental psychology, artificial intelligence, human reasoning and problem solving, and primatology. These themes include the importance of sensitivity to goal structure rather than action sequences in intelligent learning, the capacity to construct and manipulate hierarchically embedded mental representations, and a troubling domain specificity in the manifestation of each.

The question of freedom in the modern German tradition is not just a metaphysical question. It concerns the status of a free life as a value, indeed, as they took to saying, the “absolute” value. A free life is of unconditional and incomparable and inestimable value, and it is the basis of the unique, and again, absolute, unqualifiable respect owed to any human person just as such. This certainly increases the pressure on anyone who espouses such a view to tell (...) us what a free life consists in. Kant’s famous answer is “autonomy,” where this means first or minimally freedom from external constraint, coercion and intimidation (“thinking for yourself”), but even more importantly, being in a certain specific sort of self-relation. I can only be said truly to be “ruling myself” when the considerations that determine what I do are reasons. But if, finally, in exercising reason I am merely rationally responsive to inclinations and desires and aversions, I am letting such contingent impulses “rule” my life, however strategically rational or hierarchically ordered my plans for satisfaction turn out to be. So, Kant concludes, I am only truly autonomous, self-ruling, when the one consideration of importance (that is, normatively authoritative) in what I do is, as he says so frequently if still mysteriously, the “ form of rationality” as such. The more familiar name for such a necessary condition of autonomy is the Categorical Imperative. To make clear that this subjection to the “form” of rationality counts as autonomy, Kant also insists that this moral law be understood as “self-legislated,” that we must be able to regard ourselves as its “author,” and that we are bound to such a law because we bind ourselves to it.

Archaeologists have proposed that behavioral knowledge of a tool can be conceptualized as a “recipe”—a unit of cultural transmission that combines the preparation of raw materials, construction, and use of the tool, and contingency plans for repair and maintenance. This parallels theories in cognitive psychology that behavioral knowledge is hierarchically structured—sequences of actions are divided into higher level, partially independent subunits. Here we use an agent-based simulation model to explore the costs and benefits of hierarchical learning relative to holistic (...) learning, where entire behavioral sequences are learned in an all-or-nothing fashion, and diffusionist learning, where actions are completely independent. Hierarchical learning is favored under the reasonable assumptions that learning is associated with some degree of both error and cost, and that behavior can be grouped into subunits that repeat in one or more tool recipes. These general predictions can be tested in the archaeological and ethnographic record. Recent advances in evolutionary developmental biology have revealed a number of parallels between the hierarchically structured, recipe-like organization of behavioral knowledge that we examine here and the manner in which biological organisms develop.

At least two distinct modeling frameworks contribute to the view that mind and brain are Bayesian: Bayesian Rational Analysis (BRA) and Hierarchical Predictive Coding (HPC). What is the relative contribution of each, and how exactly do they relate? In order to answer this question, we compare the way in which these two modeling frameworks address different levels of analysis within Marr’s tripartite conception of explanation in cognitive science. Whereas BRA answers questions at the computational level only, many HPC-theorists answer (...) questions at the computational, algorithmic, and implementational levels simultaneously. Given that all three levels of analysis need to be addressed in order to explain a behavioral or cognitive phenomenon, HPC seems to deliver more complete explanations. Nevertheless, BRA is well-suited for providing a solution to the dark room problem, a major theoretical obstacle for HPC. A combination of the two approaches also combines the benefits of an embodied-externalistic approach to resolving the dark room problem with the idea of a persisting evidentiary border beyond which matters are out of cognitive reach. For this reason, the development of explanations spanning all three Marrian levels within the general Bayesian approach may require combining the BRA and HPC modeling frameworks. (shrink)

For principled and substantially philosophical reasons, based largely on his reform of natural history by inverting the Paleyan notion of overarching and purposeful beneficence in the construction of organisms, Darwin built his theory of selection at the single causal level of individual bodies engaged in unconscious struggle for their own reproductive success. But the central logic of the theory allows selection to work effectively on entities at several levels of a genealogical hierarchy, provided that they embody a set of requisite (...) features for defining evolutionary individuality. Genes, cell lineages, demes, species, and clades-as well as Darwin’s favoured organisms-embody these requisite features in enough cases to form important levels of selection in the history of life. R. A. Fisher explicitly recognized the unassailable logic of species selection, but denied that thsi real process could be important in evolution because, compared with the production of new organisms within a species, the origin of new species is so rare, and the number of species within most clades so low. I review this and other classical arguments against higher-level selection, and conclude that they are invalid in practice for interdemic selection, and false in principle for species selection. Punctuated equilibrium defines the individuality of species and refutes Fisher’s classical argument based on cycle time. In the second part of the paper, I argue that we have failed to appreciate the range and power of selection at levels above and below the organismic because we falsely extrapolate the defining properties of organisms to these other levels, and then regard the other levels as impotent because their effective individuals differ so much from organisms. We would better appreciate the power and generality of hierarchical models of selection if we grasped two key principles: first, that levels can interact in all modes, and not only in the negative style that, for heuristic and operational reasons, has received almost exclusive attention in the existing literature; and second, that each hierarchical level differs from all others in substantial and interesting ways, both in the style and frequency of patterns in change and causal modes.

The introduction of computer simulation to paleobiology ushered in a new, experimental style of reasoning. Rather than starting with observed fossil patterns and hypothesizing causal processes that may have produced them, it became possible to start with a process model, and from it to simulate a range of possible patterns. ;The MBL Model is a stochastic model of phylogenetic evolution . Computer simulations conducted with the MBL Model served as thought experiments in stochastic evolution. In the MBL work, similarities (...) between empirical and stochastically simulated clades mounted a visual argument that stochastic processes potentially explained large fluctuations in diversity. Stanley and others countered that the similarities were an artifact of scaling. The scaling problem may have been obscured by visual bias: measures of clade shape are scale-invariant, but diversification itself is highly scale-dependent. ;Null and neutral models are frequently conflated. Null models generate hypothetical data distributions under conditions that exclude some process of interest to test whether patterns in an actual data distribution provide statistical evidence for that process. A neutral model assumes selective equivalence among all units at a specified hierarchical level in the evolving system. Neutral models are often inappropriate as null models. Pattern recognition presupposes a null model, but tacit null models are subject to persistent cognitive biases, necessitating explicit formulation of null models. Nonetheless, failure to reject the null model should not preclude further investigation of a pattern. ;Often, models are not candidates for falsification, but serve to simulate data for testing concepts or methods. Sepkoski and Kendrick , and Robeck, Maley, and Donoghue used the MBL Model to test whether mass extinction periodicity is an artifact of paraphyly in taxonomic data. Such numerical experiments, which make all assumptions explicit, can serve as templates for localizing points of disagreement. Models may fall into lineages, each generation providing lessons for the next, but often sharing operational assumptions. Artifacts of shared operational assumptions are often a threat to the validity of inferences. Results holding across models should not be accepted unless they withstand rigorous robustness analysis.

Tagba is a tone language that presents tonal patterns that appear quite regular at first glance. However, these are difficult to model under standard autosegmental hierarchical assumptions regarding the placement of skeleton, segments and tones. In this paper, we will present Tagba tonology and demonstrate that it can be accounted for by readjusting the tiers of hierarchization. From this, we reason that the proposed hierarchy is parametric and language specific.

Expert reasoning combines voluminous domain‐specific knowledge with more general factual and strategic knowledge. Whereas expert system builders have recognized the need for specificity and problem‐solving researchers the need for generality, few attempts have been made to develop expert reasoning engines combining different kinds of knowledge at different levels of generality. This paper reports on the FERMI project, a computer‐implemented expert reasoner in the natural sciences that encodes factual and strategic knowledge in separate semantic hierarchies. The principled decomposition of (...) knowledge according to type and level of specificity yields both power and cross‐doman generality, as demonstrated in FERMI's ability to apply the same principles of invariance and decomposition to solve problems in fluid statics, DC‐circuits, and centroid location. Hierarchical knowledge representation and problem‐solving principles are discussed, and illustrative problem‐solving traces are presented. (shrink)

Individuals who disagree that organizational interests legitimately supersede those of the wider society may experience conflict between their personal standards of ethics and those demanded by an employing organization, a conflict that is well documented. An additional question is whether or not individuals capable of complex moral reasoning experience greater conflict than those reasoning at a less developed level. This question was first positioned in a theoretical framework and then investigated using 115 survey responses from a student sample. (...) Correlational analysis and hierarchical regression indicated that individuals scoring high on the Defining Issues Test measure of Kohlberg's stages of moral development experienced significantly greater workplace ethical conflict than low scorers. The finding that complex moral reasoners perceive greater conflict between their personal standards and typical organizational demands raises the issue of what reasoning orientation is rewarded in organizations. Individuals capable of complex moral reasoning may be likely to leave traditional organizations due to high conflict but more ethically friendly organizations for complex reasoners seem unlikely unless these people occupy influential positions.

Previous work suggests that moral intensity and the perceived importance of an ethical issue can influence individual ethical decision making. However, prior research has not explored how the various dimensions of moral intensity might differentially affect PIE, or how moral intensity might function together with (or in the presence of) PIE to influence ethical decision making. In addition, prior work has also not adequately investigated how the operational context of an organization, which may embody conditions or practices that create barriers (...) to ethical decision making, may differ from other functional areas of an organization. Consequently, this study investigated the relationships among moral intensity, perceived ethical issue importance, and three stages of the ethical reasoning process: recognition of an ethical issue, ethical judgment, and ethical intention. Using an internet-based, self-report survey containing two operations management scenarios and various ethics measures, information was collected from business professionals working for a Midwestern financial services organization. The hierarchical regression results indicated that some dimensions of moral intensity were positively related to PIE, ethical issue recognition, and ethical judgment, and that PIE was associated with increased ethical issue recognition and ethical judgment. The steps of ethical reasoning were also positively interrelated. (shrink)

The immediate purpose of this paper is to expound C. S. Peirce's conception of reasoning as he refined it in his mature reflection on the normative sciences and their hierarchical relations (the dependence of logic on ethics and, in turn, that of ethics on esthetics). In order to clarify adequately Peirce's position, however, it is helpful to consider his rejection of Christoph Sigwart's attempt to ground logical soundness in subjective feeling. What is at stake in this debate is (...) nothing less than Peirce's endeavor to articulate a thoroughly pragmatic understanding of truth, not simply his commitment to argue against subjective approaches to logical questions. Accordingly, the ultimate purpose of this paper is to shed light on the problem of objectivity. From a pragmatist perspective, there is an essential relation between an affectively involved agent and a deliberately conducted, successful inquiry. This alone secures the possibility of objectivity in the only form in which finite, fallible agents can hope to attain or, at least, approximate this ideal. (shrink)

Intuitively, the more powerful a theory is, the greater the variety and quantity of ideas can be expressed through its formal language. Therefore, when comparing two theories concerning the same subject, it seems only reasonable to compare the expressive powers of their formal languages. On condition that the quantum mechanical description is universal and so can be applied to macroscopic systems, quantum theory is required to be more powerful than classical mechanics. This implies that the formal language of Hilbert space (...) theory must be more expressive than that of Zermelo-Fraenkel set theory. However, as shown in the paper, such a requirement cannot be met. As a result, classical and quantum formalisms cannot be in a hierarchical relation, that is, include one another. This fact puts in doubt the quantum-classical correspondence and undermines the reductionist approach to the physical world. (shrink)

In Kant scholarship, the concept of maxims is discussed, for the most part, from the perspective of the universalization procedure of the Categorical Imperative. In fact, however, it has a much wider relevance. As is shown in this contribution, maxims are fundamental to Kant’s theory of action and value. Since the agent expresses her pro-attitudes, i.e., interests, preferences, and life-plans based on maxims, they figure as constitutive elements of her practical identity. After some general and historical considerations on Kant’s concept (...) of maxims, it is shown that their function in the theory of the ‘practical syllogism’ implies that maxims play an important role in considerations on the agent’s ends, goals, and purposes. Additionally, I will discuss the function of maxims in Kant’s action theory. I will defend an interpretation of the Kantian idea according to which practical deliberation can be understood based on a hierarchical order of maxims. Finally, the problem of higher-order maxims and the issue of the unity and inner consistency of maxims is debated. (shrink)

The chapter provides illustrations of the link between Hegel's work and Vygotsky's and shows how the argument that Vygotsky employed an abstract decontextualised form of reason, is groundless. Kant sets out to resolve the dualism of world and mind by positing the categories of understanding. Although Kant's later work moved towards overcoming the rigid separation of concept and intuition and of spontaneity from receptivity, dualism remained. Hegel dealt with dualism from a radically different standpoint, and this transformed the terms in (...) which it can be posed. In contrast to Kant, he rejected the categorical separation of subject and object, thereby opening a philosophical space within which the antinomies of dualism could be transcended. Most reactions to Hegel after Marx were intermingled with reactions to Marx. Misinterpretation of Hegel is communicated to readings of Vygotsky, where the influence of Hegel is read as evidence of hierarchical conceptions of abstract reason. (shrink)

reality is a complex affair. It comprises a huge variety of different elements. Importantly, though, reality is not a mere aggregate of its elements but rather a structured whole or system whose building blocks are not all on the same level. Instead, they form hierarchical networks ordered by relations of priority. In such networks, derivative aspects of reality obtain in virtue of their grounds, that is, in virtue of more fundamental aspects of reality that are prior to them.This picture (...) of reality as a structured whole is currently enjoying a renaissance in the works of philosophers such as Kit Fine, Jonathan Schaffer, and many others.

In the context of feminist and postmodern thought, traditional conceptions of masculinity and what it means to be a “Real Man” have been critiqued. In Genevieve Lloyd's The Man of Reason, this critique takes the form of exposing the effect that the distinctive masculinity of the “man of reason” has had on the history of philosophy. One major feature of the masculine-feminine dichotomy will emerge as a key notion for understanding the rest of the paper: the dichotomy of reason-feeling, a (...) parallel and a foundational aspect to the dichotomy of masculinity and femininity. In exploring the history of symbolic conceptions of masculinity in ancient Greece, the Renaissance, and the present, one finds that the oppression of women is integrally linked to the traditional tie between masculinity and reason. There have been many efforts in recent feminist philosophy to rewrite or redefine “Woman” in such a way as to alleviate the oppression of women. I argue that the effectiveness of rewriting Woman for this purpose is problematic, primarily because any rewriting of this type must occur in the current historical context of hierarchical dualisms, like Man-Woman, masculine-feminine, male-female. These binary oppositions arguably find their roots in Pythagorean philosophy and can be traced through the Renaissance to our current historical context. It is these dualisms that have traditionally valued the masculine side of the Man-Woman dichotomy more than the feminine. Further, it will be argued that the hierarchical dualism of Man and Woman is so pervasive that if we rewrite or redefine the inferior, deprivileged side of that dualism, we cannot correct its devalued status. Instead, we redefine that which is undervalued but retain its devalued status. This particular aspect of attempts to critique hierarchical dualisms like reason and feeling has been reflected in the writings of many feminists, male and female. This paper will show that in cases where women attempt to redefine the dichotomy by revaluing the traditionally feminine (like feelings and emotions) over the traditionally masculine (like reason) their work is often mistakenly criticized for being purely political; conversely, when men attempt to redefine the same dichotomy in an attempt to allow men to “get back in touch with their feelings,” to be nurturers, their work is described in terms of providing a better epistemology. The current literature on masculinity explores alternatives to rewriting or redefining Woman that try to avoid the problem of status remaining with redefinition. This alternative is rewriting or redefining Man. Through redefining Man, one may be able to reconceptualize the privileged side of the hierarchical dualism in such a way that it is no longer privileged. Deprivileging, as well as redefining Man, is argued by theorists of masculinity to be possible because while the devalued status of the inferior side of a hierarchical dualism tends to keep the same status when redefined, it may be possible to redefine the privileged side of the dualism in such a way that it loses its privileged status. Unfortunately, many of these attempts to rewrite or redefine masculinity have detrimental faults of their own. Finally, this paper will discuss more promising possibilities for new definitions of Man, as well as a vision for better interaction between the work of women and men in general. (shrink)

Previous work suggests that gender attitudes are associated with different individual and organizational factors. At the same time, ethics research suggests that many of these same variables can influence ethical reasoning in companies. In this study, we sought to combine these streams of research to investigate whether individual skepticism of women's employment is related to ethical reasoning in a gender-based ethical situation. The results of the hierarchical regression analysis indicated that skepticism of women's employment was negatively related (...) to the recognition that the gender-based dilemma involved an ethical problem, and that skepticism was also negatively related to judgments that the situation was unethical. These findings imply that companies should advance policies that increase tolerance for women's employment, such as diversity training codes of conduct, and ethics training. (shrink)

The ancient puzzle of the Liar was shown by Tarski to be a genuine paradox or antinomy. I show, analogously, that certain puzzles of contemporary game theory are genuinely paradoxical, i.e., certain very plausible principles of rationality, which are in fact presupposed by game theorists, are inconsistent as naively formulated. ;I use Godel theory to construct three versions of this new paradox, in which the role of 'true' in the Liar paradox is played, respectively, by 'provable', 'self-evident', and 'justifiable'. I (...) also construct in modal operator logic a paradox involving reflexive empirical reasoning. Unlike the paradox of the Liar, the paradox of reflexive reasoning does not depend on self-reference. ;I consider various solutions to the Liar paradox and evaluate how well these solutions cope with the paradox of reflexive reasoning. I then formalize the solution to the paradoxes which I favor: the indexical-hierarchical approach, first sketched out by Charles Parsons and Tyler Burge. In this solution, occurrences of the predicate 'true' in sentence-tokens are contextually relativized to levels of a hierarchy. Drawing also on some brief remarks of Bertrand Russell and Charles Parsons, I develop an account of the kind of schematic generality needed for this theory to be statable. ;Finally, I demonstrate that the principles shown to be paradoxical are in fact presupposed by contemporary game theorists in their reliance on the notion of common knowledge or, more precisely, mutual belief. I create novel analyses of and corresponding solutions to several recalcitrant puzzles within game theory, including the "chain-store paradox". (shrink)

In Roman Catholic moral theology there is an ongoing debate between the proportionalist or revisionist school and the traditionalist school that has developed what is referred to as the ‘New Natural Law Theory’ or ‘Basic Goods Theory’ . The stakes in this debate have been raised with Pope John Paul II's encyclical Veritatis Splendor on fundamental moral theology that condemned ‘proportionalism’ or ‘teleologism’ as an ethical theory while utilizing many of the ideas, concepts, and terminology of the BGT, thereby implicitly (...) endorsing that ethical theory. While absolute norms and intrinsically evil acts have frequently been the focus of debate between these two schools, what is it that divides them fundamentally, on the level of ethical method? It is the role and function of reason and experience as two sources of moral knowledge, in part, that distinguish these two versions of natural law on the most basic level. While the BGT has a strict hierarchy of the sources of moral knowledge that posits the hierarchical magisterium as the definitive interpreter of reason and experience, revisionists posit a more dialogical relationship between reason, experience, and the magisterium. On certain ethical issues , the experience of the faithful as well as the rational arguments developed by revisionist Catholic moral theologians challenge some of the normative claims of the magisterium. This paper investigates the methodological use of reason and experience in each theory's interpretation of natural law and how and why these two sources of moral knowledge lead to fundamentally divergent normative claims on particular ethical issues.

In this thesis, I develop and investigate various novel semantic frameworks for deontic logic. Deontic logic concerns the logical aspects of normative reasoning. In particular, it concerns reasoning about what is required, allowed and forbidden. I focus on two main issues: free-choice reasoning and the role of norms in deontic logic. -/- Free-choice reasoning concerns permissions and obligations that offer choices between different actions. Such permissions and obligations are typically expressed by a disjunctive clause in the (...) scope of a deontic operator. For instance, the sentence "Jane may take an apple or a pear" intuitively offers Jane a choice between two permitted courses of action: she may take an apple, and she may take a pear. In the first part of the thesis, I develop semantic frameworks for deontic logic that account for free-choice reasoning. I show that the resulting logics avoid problems that arise for other logical accounts of free-choice reasoning. The main technical contributions are completeness results for axiomatizations of the different logics. -/- Semantic frameworks for deontic logic typically only talk about norms implicitly. In the second part of the thesis, I clarify the role of norms in deontic logic. I develop a formal model of normative systems where norms are represented explicitly. The model takes into account both the hierarchical structure of normative systems, and the function of norms to regulate agent behavior. I show how the model can be used to clarify issues in the study of normative systems. I also develop a norm-based semantics for deontic action logic based on the model. (shrink)

This paper provides a new compatibilist definition of free will, which is an elaboration of the classic compatibilist view of free will as absence of restriction, with the help of the causal theory of action and some special categories. This new definition enables us to neutralize a very wide range of counterexamples in a systematic and compelling way, including those left unanswered by hierarchical definitions.1.

These two small works are a good supplement to Rescher’s recent trilogy. Whereas the systems-theoretic approach is employed in Methodological Pragmatism in dealing with the problem of the legitimation of claims to factual knowledge or cognitive rationality, Dialectics deals with the argumentation aspect of thesis-introduction rather than the logical aspect of thesis-derivation. Although some key notions such as the idea of burden of proof and presumption have been stated in the former work, what is offered here is a systematic discussion (...) of a disputational model of inquiry. The principal aims are "to exhibit the sociocommunal roots of the foundations of rationality, to provide an instrument for the critique of scepticism implicit in the cognitive solipsism of the Cartesian approach, and to illuminate the communal and controversy-oriented aspects of rational argumentation and inquiry—scientific inquiry in particular." Again, Rescher limits his discussion to "the probative mechanism in the factual domain." This book, if it were not for its price, should be a good supplement to a course in "informal" logic which focuses on argumentation rather than on mere evaluation of arguments. Plausible Reasoning provides the mechanism for evaluation of plausibility claims as distinct from probabilistic ones. The basic differences between these two types of claims are clearly discussed. "Plausibility is essentially a classificatory concept which ranks theses in terms of the standing and solidity of their cognitive basis. Plausibility grades theses by an external or extrinsic standard of the hierarchical nature of their supporting bases. It classifies propositions by the status of the evidential sources or validating principles that vouch for them. Probability weighs alternatives and evaluates theses by this relative contentual weight of the supporting considerations."—A.S.C. (shrink)

Previous work suggests that gender attitudes are associated with different individual and organizational factors. At the same time, ethics research suggests that many of these same variables can influence ethical reasoning in companies. In this study, we sought to combine these streams of research to investigate whether individual skepticism of women’s employment is related to ethical reasoning in a gender-based ethical situation. The results of the hierarchical regression analysis indicated that skepticism of women’s employment was negatively related (...) to the recognition that the gender-based dilemma involved an ethical problem, and that skepticism was also negatively related to judgments that the situation was unethical. These findings imply that companies should advance policies that increase tolerance for women’s employment, such as diversity training codes of conduct, and ethics training. (shrink)

The capacity to generate recursive sequences is a marker of rich, algorithmic cognition, and perhaps unique to humans. Yet, the precise processes driving recursive sequence generation remain mysterious. We investigated three potential cognitive mechanisms underlying recursive pattern processing: hierarchical reasoning, ordinal reasoning, and associative chaining. We developed a Bayesian mixture model to quantify the extent to which these three cognitive mechanisms contribute to adult humans’ performance in a sequence generation task. We further tested whether recursive rule discovery (...) depends upon relational information, either perceptual or semantic. We found that the presence of relational information facilitates hierarchical reasoning and drives the generation of recursive sequences across novel depths of center embedding. In the absence of relational information, the use of ordinal reasoning predominates. Our results suggest that hierarchical reasoning is an important cognitive mechanism underlying recursive pattern processing and can be deployed across embedding depths and relational domains.

As Kant claimed in the Groundwork, and as the idea has been developed by Korsgaard 1997, Bratman 1987, and Broome 2002. This formulation is agnostic on whether reasons for ends derive from our desiring those ends, or from the relation of those ends to things of independent value. However, desire-based theorists may deny, against Hubin 1999, that their theory is a combination of a principle of instrumental transmission and the principle that reasons for ends are provided by desires. Instead, they (...) may say, there is just one principle, a principle of, if you will, instrumental transmutation: if one desires the end, then one has reason to take the means. See the discussion of General Production, in section 8, for a doubt about this. (shrink)
