Zur Miete bei Frege – Rudolf Hirzel und die Rezeption der stoischen Logik und Semantik in Jena

It has been noted before in the history of logic that some of Frege's logical and semantic views were anticipated in Stoicism. In particular, there seems to be a parallel between Frege's Gedanke (thought) and Stoic lekton; and the distinction between complete and incomplete lekta has an equivalent in Frege's logic. However, nobody has so far claimed that Frege was actually influenced by Stoic logic; and there has until now been no indication of such a causal connection. In this essay, we attempt, for the first time, to provide detailed evidence for the existence of this connection. In the course of our argumentation, further analogies between the positions of Frege and the Stoics will be revealed. The classical philologist Rudolf Hirzel will be brought into play as the one who links Frege with Stoicism. The renowned expert on Stoic philosophy was Frege's tenant and lived in the same house as the logician for many years.

In der Geschichte der Logik ist häufig bemerkt worden, dass einige der logischen und semantischen Auffassungen Freges in der Stoa antizipiert worden sind. Genannt wurden insbesondere die Parallelen zwischen dem Fregeschen Gedanken und dem stoischen Lekton sowie die Unterscheidung zwischen vollständigen und unvollständigen Lekta, die bei Frege ihre Entsprechung hat. Ein Wirkungszusammenhang ist allerdings nicht behauptet worden. Dazu gab es bislang auch keinen Anlass. Der vorliegende Beitrag versucht erstmalig, einen detaillierten Indizienbeweis für das Bestehen eines solchen Zusammenhangs vorzulegen. Dabei werden weitere charakteristische Übereinstimmungen zwischen Frege und der Stoa aufgewiesen. Als Mittelsmann wird der Altphilologe Rudolf Hirzel vorgestellt. Er wohnte lange Jahre als Mieter zusammen mit Frege im selben Haus und war ein anerkannter Experte der stoischen Philosophie.     

Cognitive extension: the parity argument,functionalism, and the mark of the cognitive

During the past decade, the so-called “hypothesis of cognitive extension,” according to which the material vehicles of some cognitive processes are spatially distributed over the brain and the extracranial parts of the body and the world, has received lots of attention, both favourable and unfavourable. The debate has largely focussed on three related issues: (1) the role of parity considerations, (2) the role of functionalism, and (3) the importance of a mark of the cognitive. This paper critically assesses these issues and their interconnections. Section 1 provides a brief introduction. Section 2 argues that some of the most prominent objections against the appeal to parity considerations fail. Section 3 shows that such considerations are nevertheless unsuitable as an argument for cognitive extension. First, the actual argumentative burden is carried by an underlying commitment to functionalism, not by the parity considerations themselves. Second, in the absence of an independently motivated mark of the cognitive, the argument based on parity considerations does not get off the ground, but given such a mark, it is superfluous. Section 4 argues that a similar dilemma arises for the attempt to defend cognitive extension by a general appeal to functionalism. Unless it can be independently settled what it is for a process to be cognitive, functionalism itself will be undermined by the possibility of cognitive extension. Like parity considerations, functionalism is thus either unable to support cognitive extension or superfluous. Hence, nothing short of the specification of an appropriate mark of the cognitive that can be fulfilled not only by intracranial but also by extended processes will do as an argument for cognitive extension.     

The Harmful Influence of Decision Theory on Ethics

In the last half century, decision theory has had a deep influence on moral theory. Its impact has largely been beneficial. However, it has also given rise to some problems, two of which are discussed here. First, issues such as risk-taking and risk imposition have been left out of ethics since they are believed to belong to decision theory, and consequently the ethical aspects of these issues have not been treated in either discipline. Secondly, ethics has adopted the decision-theoretical idea that action-guidance has to be based on cause–effect or means–ends relationships between an individual action and its possible outcomes. This is problematic since the morally relevant connections between an action and future events are not fully covered by such relationships. In response to the first problem it is proposed that moral theory should deal directly and extensively with issues such as risk-taking and risk imposition, thereby intruding unabashedly into the traditional territory of decision theory. As a partial response to the second problem it is proposed that moral theorizing should release itself from the decision-theoretical requirement that the moral status of an action has to be derivable from the consequences (or other properties) that are assignable to that action alone. In particular, the effects that an action can have in combination with other actions by the same or other agents are valid arguments in an action-guiding moral discourse, even if its contribution to these combined consequences cannot be isolated and evaluated separately.     

Culture or anonymity? Differences in proposer behaviour in Korea and Germany

This study explores the proposer behaviour in an ultimatum game (UG) frame under anonymous and non‐anonymous conditions among a Korean and German subject pool (n = 590) in comparison. Whereas the anonymous condition is represented by the standard UG, the non‐anonymous condition integrates an aggregate of the Korean cultural context variables university affiliation, regional origin and seniority. The latter, a classic Confucian context variable, is measured by age differentials. The former two are impactful components of so‐called Yongo networks, a unique Korean informal institution identical to Chinese Guanxi ties. Yongo networks, yet underrepresented in research, are said to be a central context variable to explain Korean social ties and decision‐making behaviour. We observe significant differences between the offer behaviours of Korean and German subjects when exposing selected cultural variables. We argue that the behavioural differences observed are in fact due to culture not anonymity.     

Linking Genes and Political Orientations: Testing the Cognitive Ability as Mediator Hypothesis

Recent research has demonstrated that genetic differences explain a sizeable fraction of the variance in political orientations, but little is known about the pathways through which genes might affect political preferences. In this article, we use a uniquely assembled dataset of almost 1,000 Swedish male twin pairs containing detailed information on cognitive ability and political attitudes in order to further examine the genetic and environmental causes of political orientations. Our study makes three distinct contributions to our understanding of the etiology of political orientations: (1) we report heritability estimates across different dimensions of political ideology; (2) we show that cognitive ability and political orientations are related; and (3) we provide evidence consistent with the hypothesis that cognitive ability mediates part of the genetic influence on political orientations. These findings provide important clues about the nature of the complex pathways from molecular genetic variation to political orientations.     

Late reaction times identify MCI

A group of 172 mild cognitive impairment (MCI) patients and 79 healthy control participants (HC) were tested on simple reaction time (SRT). There was a significant difference between MCI and HC in mean SRT. The test could be partitioned into five segments of 16 trials each, but RT's were not always available for each partition. However, scores from each segment for 166 MCI and 41 of the HC's were available. These data showed that a significant interaction between RT‐partition and diagnostic category was the main source of the difference between groups. The interaction indicated that MCI patients performed at about the same level as HC in the initial three of the five segments of the test, but were significantly impaired during the last two segments of the 80 trials. The results were interpreted as impaired sustained attention among a large part of the MCI group, and the study shows the importance of taking into account all avaliable data resulting from this type of test.     

Rhyme as reason in commercial and social advertising

This study investigated the rhyme‐as‐reason effect on new artificially created advertising slogans. Rhymes and non‐rhymes were in Experiment 1 and 2 compared in a between‐subjects design and in Experiment 3 in a within‐subjects design. The quality of the form and content of the slogans was always evaluated by separate groups. In Experiment 1, we found a strong preference for rhyming slogans as opposed to their non‐rhyming counterparts. Rhymes were rated as more likeable, more original, easier to remember, more suitable for campaigns, more persuasive and more trustworthy. In Experiment 2, social advertising messages were evaluated favorably in both rhyming and non‐rhyming versions. However, when participants directly compared rhymes and non‐rhymes on the same scale (Experiment 3), the difference between commercial and social advertising disappeared and for all slogans rhymes were clearly preferred to non‐rhymes in terms of both form and content. A detailed analysis revealed that the rhymes scoring high on formal aspects were also favored in the questionnaire investigating content aspects.     

Social Learning,Social Disorganization,and Psychological Risk Factors for Criminal Gangs in a British Youth Context

ABSTRACT

Using longitudinal data from a British longitudinal cohort study (ALSPAC), the current study examines “developmental domains” from individual, peer, and community risk factors. Using four logistic regression models, we looked at 10 correlations between children’s experience with risk factors outlined by the literature and criminal gang association. Gang membership was associated with drug use, delinquent peers, and disorganized neighborhoods. Further, early diagnoses of childhood aggression, ADHD, depression, and Oppositional Defiant Disorder, were not associated with later, adolescent youth gang membership. Our results suggest community based programs that stem from social learning policies and collective efficacy militate against gang growth.     

Why Did They Claim Too Much? The Role of Causal Attributions in Explaining Level of Cooperation in Commons and Anticommons Dilemmas

The present study ( N  = 200) investigated participants' attributions for explaining the behavior of noncooperative and cooperative targets in a commons and anticommons dilemma. The attribution dimensions of concern for others, fear, (low levels of) greed, and efficiency were highly related and were interpreted to reflect prosocial orientation. Cooperative targets were judged as more prosocial, but these differences were more pronounced in the commons than in the anticommons dilemma. Crossover interaction effects were obtained for ignorance and fear, revealing higher attribution scores for the noncooperative target in the commons dilemma and the cooperative target in the anticommons dilemma. It is argued that commons and anticommons dilemmas constitute different frames of reference for judging cooperative behavior.     

Group-level self-definition and self-investment: a hierarchical (multicomponent) model of in-group identification

Recent research shows individuals' identification with in-groups to be psychologically important and socially consequential. However, there is little agreement about how identification should be conceptualized or measured. On the basis of previous work, the authors identified 5 specific components of in-group identification and offered a hierarchical 2-dimensional model within which these components are organized. Studies 1 and 2 used confirmatory factor analysis to validate the proposed model of self-definition (individual self-stereotyping, in-group homogeneity) and self-investment (solidarity, satisfaction, and centrality) dimensions, across 3 different group identities. Studies 3 and 4 demonstrated the construct validity of the 5 components by examining their (concurrent) correlations with established measures of in-group identification. Studies 5-7 demonstrated the predictive and discriminant validity of the 5 components by examining their (prospective) prediction of individuals' orientation to, and emotions about, real intergroup relations. Together, these studies illustrate the conceptual and empirical value of a hierarchical multicomponent model of in-group identification.
