Freud proposes that in unconscious processing, logical connections are also (heavily) based upon phonological similarities. Repressed concerns, for example, would also be expressed by way of phonologic ambiguity. In order to investigate a possible unconscious influence of phonological similarity, 31 participants were submitted to a tachistoscopic subliminal priming experiment, with prime and target presented at 1ms. In the experimental condition, the prime and one of the 2 targets were phonological reversed forms of each other, though graphemically dissimilar (e.g., “nice” and (...) “sign”); in the control condition the targets were pseudo-randomly attributed to primes to which they don’t belong. The experimental task was to “blindly” pick the choice most similar to the prime. ERPs were measured with a focus on the N320, which is known to react selectively to phonological mismatch in supraliminal visual word presentations. The N320 amplitude-effects at the electrodes on the midline and at the left of the brain significantly predicted the participants’ net behavioral choices more than half a second later, while their subjective experience is one of arbitrariness. Moreover, the social desirability score (SDS) significantly correlates with both the behavioral and the N320 brain responses of the participants. It is proposed that in participants with low SDS the phonological target induces an expected reduction of N320 and this increases their probability to pick this target. In contrast, high defensive participants have a perplexed brain reaction upon the phonological target, with a negatively peaking N320 as compared to control and this leads them to avoid this target more often. Social desirability, which is understood as reflecting defensiveness, might also manifest itself as a defense against the (energy-consuming) ambiguity of language. The specificity of this study is that all of this is happening totally out of awareness and at the level of very elementary linguistic distinctions. (shrink)

This paper explores allowing truth value assignments to be undetermined or "partial" and overdetermined or "inconsistent", thus returning to an investigation of the four-valued semantics that I initiated in the sixties. I examine some natural consequence relations and show how they are related to existing logics, including ukasiewicz's three-valued logic, Kleene's three-valued logic, Anderson and Belnap's relevant entailments, Priest's "Logic of Paradox", and the first-degree fragment of the Dunn-McCall system "R-mingle". None of these systems have nested implications, and I investigate (...) twelve natural extensions containing nested implications, all of which can be viewed as coming from natural variations on Kripke's semantics for intuitionistic logic. Many of these logics exist antecedently in the literature, in particular Nelson 's "constructible falsity". (shrink)

The release of genetically engineered organisms into the shared environment raises scientific, ethical, and societal issues. Using some form of democratic deliberation to provide the public with a voice on the policies that govern these technologies is important, but there has not been enough attention to how we should connect public deliberation to the existing regulatory process. Drawing on lessons from previous public deliberative efforts by U.S. federal agencies, we identify several practical issues that will need to be addressed if (...) relevant federal agencies are to undertake public deliberative activities to inform decision‐making about gene editing in the wild. We argue that, while agencies may have institutional capacity to undertake public deliberative activities, there may not be sufficient political support for them to do so. Advocates of public deliberation need to make a stronger case to Congress about why federal agencies should be encouraged and supported to conduct public deliberations. (shrink)

Arnon Avron has written: “Dunn-McCall logic RM is by far the best understood and the most well-behaved in the family of logics developed by the school of Anderson and Belnap.” I agree. There is the famous saying: “Do not let the perfect become the enemy of the good.” I might say: “good enough.” In this spirit, I will examine the logic R-Mingle, exploring how it is only a “semi-relevant logic” but still a paraconsistent logic. I shall discuss the history of (...) RM, and compare RM to Anderson and Belnap’s system R of relevant implication and to classical two-valued logic. There is a “consumer’s guide,” evaluating these logics as “tools,” in the light of my recent work on “Humans as Rational Toolmaking Animals.”. (shrink)

Classical sentences that are true in are non-false in . Applications to number theory and type theory (with axiom of infinity) produce finite 3-valued models in which all classically true sentences of these theories are non-false.

Meyer and suggested the present abstract development). (shrink)

If a man born blind were to gain his sight in later life would he be able to identify the objects he saw around him? Would he recognise a cube and a globe on the basis of his earlier tactile experiences alone? This was William Molyneux's famous question to John Locke and it was much discussed by English and French empiricists in the eighteenth century as part of the controversy over innatism and abstract ideas. Dr Morgan examines the whole history (...) of this debate: Locke's own (negative) answer to the question, the contributions of Berkeley, Condillac, Diderot and Voltaire and the factual accounts of early cataract operations and modern laboratory studies. He shows how this debate is involved in the development and eventual separation of philosophy and experimental psychology after the eighteenth century and considers why the original question is effectively still unanswered. This is one problem-area with its intricate cluster of connected conceptual and technical difficulties which suggests the need for some reunion or at least collaboration between the two subjects.

Results of a study investigating the relation between personality traits and ethical-orientation indicate sex is not an good predictor for differences in Machiavellian-, Type A personality- or ethical-orientation. Intelligence is found to be positively associated with Machiavellian- and Type A personality-orientation but negatively associated with ethical-orientation. Machiavellians tend to have Type A personalities, but tend to be less ethically-oriented than Nonmachiavellians. Type A personalities are more ethically-orientated than Type B personalities.

Email: michael.selgelid{at}anu.edu.au ' + u + '@ ' + d + ' '/ /- ->. Home page: http: //www.cappe.edu.au/staff/michael-selgelid.htmThis article advocates the development of a moderate pluralist theory of political philosophy that recognizes that utility, liberty and equality are legitimate, independent social values and that none should have absolute priority over the others. Inter alia, such a theory would provide (...) a principled means for striking a balance, or making trade-offs, between these values in cases of conflict. Recent developments in public health ethics have made progress in thinking about how to make trade-offs between liberty and utility in particular. While public health ethicists often claim that the least restrictive alternative should be used to achieve the public health goal in question, I argue that a plausible but under-recognized idea is that the least restrictive alternative might sometimes involve improvement of global health via redistributive taxation—i.e., rather than coercive social distancing measures. I conclude by demonstrating that the proportionality principle leaves open the question of when exactly utility outweighs liberty or vice versa—and I argue that, rather than speaking about the morality of liberty-infringing public health interventions in categorical/binary terms, it would be more fruitful and realistic to think and speak about the degree to which a liberty-infringing public health intervention is morally appropriate.

Using a pretest-posttest quasi-experimental control group design, a learning environment study was conducted to evaluate the environmental literacy of postsecondary, nonscience majors. Data were collected from 183 students taking an introductory environmental science class—a 41-question Environmental Literacy Instrument (ELI) prompted students for responses across four subscales of environmental literacy: Knowledge, Beliefs, Opinions, and Self-Perceptions. Differences between presurvey and postsurvey scores were compared to determine whether a constructivist-based or traditional learning environment improved students' environmental literacy more. Results showed that the constructivist-based (...) curriculum was not a significant factor of influence, suggesting that regardless of which learning environment they were exposed to, participants experienced similar improvements to their environmental literacy across a 16-week semester. Given that the findings were contrary to expectations, and counterindicated by several other learning environment studies as well, a broader investigation as to why the two learning environments produced similar results is warranted.

In this paper we introduce canonical extensions of partially ordered sets and monotone maps and a corresponding discrete duality. We then use these to give a uniform treatment of completeness of relational semantics for various substructural logics with implication as the residual(s) of fusion.

The rise in the public profile of “alt-right” and “white nationalist” groups in recent years is often described as a rise in “hate groups.” The presumption in this nomenclature is that these sorts of groups are defined essentially in terms of their shared hatred for some or all nonwhite individuals and groups. However, the rhetoric of such groups is couched not as hatred, but rather in terms of “self-love”—they do not hate other groups, they are just looking out for themselves. (...) The author's argument in this article is that, even if we assume the sincerity of white nationalists' claims to be only interested in sustaining and defending whites and whiteness, the kind of “self-love” this exhibits is morally and politically pernicious precisely because it is constitutively linked to a foundational contempt for nonwhites.

While each Form is what it is to be F, some Forms also instantiate F (or “self-instantiate”). Here I consider whether the explanation for a Form’s instantiating F should be the Form’s participating in itself. First, I motivate the need for an explanation of self-instantiation. Second, I consider the advantages and disadvantages of self-participation alongside an alternative explanation—that the Form’s being what it is to be F is a sufficient explanation of its instantiation of F. The result is not a (...) conclusive case for self-participation, but only some initial considerations in favor of it. (shrink)

Neuroimaging offers great potential to clinicians and researchers for a host of mental and physical conditions. The use of imaging has been trumpeted for forensic psychiatric and psychological evaluations to allow greater insight into the relationship between the brain and behavior. The results of imaging certainly can be used to inform clinical diagnoses; however, there continue to be limitations in using neuroimaging for insanity cases due to limited scientific backing for how neuroimaging can inform retrospective evaluations of mental state. In (...) making this case, this paper reviews the history of the insanity defense and explains how the use of neuroimaging is not an effective way of improving the reliability of insanity defense evaluations.

This article describes some potential uses of Bayesian estimation for time-series and panel data models by incorporating information from prior probabilities (i.e., priors) in addition to observed data. Drawing on econometrics and other literatures we illustrate the use of informative “shrinkage” or “small variance” priors (including so-called “Minnesota priors”) while extending prior work on the general cross-lagged panel model (GCLM). Using a panel dataset of national income and subjective well-being (SWB) we describe three key benefits of these priors. First, they (...) shrink parameter estimates toward zero or toward each other for time-varying parameters, which lends additional support for an income → SWB effect that is not supported with maximum likelihood (ML). This is useful because, second, these priors increase model parsimony and the stability of estimates (keeping them within more reasonable bounds) and thus improve out-of-sample predictions and interpretability, which means estimated effect should also be more trustworthy than under ML. Third, these priors allow estimating otherwise under-identified models under ML, allowing higher-order lagged effects and time-varying parameters that are otherwise impossible to estimate using observed data alone. In conclusion we note some of the responsibilities that come with the use of priors which, departing from typical commentaries on their scientific applications, we describe as involving reflection on how best to apply modeling tools to address matters of worldly concern.

In this paper two different formulations of Robinson's arithmetic based on relevant logic are examined. The formulation based on the natural numbers (including zero) is shown to collapse into classical Robinson's arithmetic, whereas the one based on the positive integers (excluding zero) is shown not to similarly collapse. Relations of these two formulations to R. K. Meyer's system R# of relevant Peano arithmetic are examined, and some remarks are made about the role of constant functions (e.g., multiplication by zero) in (...) relevant arithmetic. (shrink)

Prominent philosophers have argued that contradictions contain either too much or too little information to be useful. We dispute this with what we call the “Paradox of the Two Firefighters.” Suppose you are awakened in your hotel room by a fire alarm. You open the door. You see three possible ways out: left, right, straight ahead. You see two firefighters. One says there is exactly one safe route and it is to your left. The other says there is exactly one (...) safe route and it is to your right. While the two firemen are giving you contradictory information, they are also both giving you the perhaps useful information that there is a safe way out and it is not straight ahead. We give two analyses. The first uses the “Opinion Tetrahedron,” introduced by Dunn as a generalization of Audun Jøsang’s “Opinion Triangle.” The Opinion Tetrahedron in effect embeds the values of the “Belnap-Dunn 4-valued Logic” into a context of subjective probability generalized to allow for degrees of belief, disbelief, and two kinds of uncertainty—that in which the reasoner has too little information and that in which the reasoner has too much information. Jøsang had only a single value for uncertainty. We also present an alternative solution, again based on subjective probability but of a more standard type. This solution builds upon “linear opinion pooling.” Kiefer had already developed apparatus for assessing risk using expert opinion, and this influences the second solution. Finally, we discuss how these solutions might apply to “Big Data” and the World Wide Web. (shrink)

Sexual size dimorphism is generally associated with sexual selection via agonistic male competition in nonhuman primates. These primate models play an important role in understanding the origins and evolution of human behavior. Human size dimorphism is often hypothesized to be associated with high rates of male violence and polygyny. This raises the question of whether human dimorphism and patterns of male violence are inherited from a common ancestor with chimpanzees or are uniquely derived. Here I review patterns of, and causal (...) models for, dimorphism in humans and other primates. While dimorphism in primates is associated with agonistic male mate competition, a variety of factors can affect male and female size, and thereby dimorphism. The causes of human sexual size dimorphism are uncertain, and could involve several non-mutually-exclusive mechanisms, such as mate competition, resource competition, intergroup violence, and female choice. A phylogenetic reconstruction of the evolution of dimorphism, including fossil hominins, indicates that the modern human condition is derived. This suggests that at least some behavioral similarities with Pan associated with dimorphism may have arisen independently, and not directly from a common ancestor. (shrink)

We study an application of gaggle theory to unary negative modal operators. First we treat negation as impossibility and get a minimal logic system Ki that has a perp semantics. Dunn 's kite of different negations can be dealt with in the extensions of this basic logic Ki. Next we treat negation as “unnecessity” and use a characteristic semantics for different negations in a kite which is dual to Dunn 's original one. Ku is the minimal logic that has a (...) characteristic semantics. We also show that Shramko's falsification logic FL can be incorporated into some extension of this basic logic Ku. Finally, we unite the two basic logics Ki and Ku together to get a negative modal logic K-, which is dual to the positive modal logic K+ in [7]. Shramko has suggested an extension of Dunn 's kite and also a dual version in [12]. He also suggested combining them into a “united” kite. We give a united semantics for this united kite of negations. (shrink)
