Justifying inference to the best explanation as a practical meta-syllogism on dialectical structures

This article discusses how inference to the best explanation (IBE) can be justified as a practical meta-argument. It is, firstly, justified as a practical argument insofar as accepting the best explanation as true can be shown to further a specific aim. And because this aim is a discursive one which proponents can rationally pursue in—and relative to—a complex controversy, namely maximising the robustness of one’s position, IBE can be conceived, secondly, as a meta-argument. My analysis thus bears a certain analogy to Sellars’ well-known justification of inductive reasoning (Sellars, In: Essays in honour of Carl G. Hempel, 1969); it is based on recently developed theories of complex argumentation (Betz, In: Theorie dialektischer Strukturen, 2010a).     

Petitio principii and circular argumentation as seen from a theory of dialectical structures

This paper investigates in how far a theory of dialectical structures sheds new light on the old problem of giving a satisfying account of the fallacy of petitio principii, or begging the question. It defends that (i) circular argumentation on the one hand and petitio principii on the other hand are two distinct features of complex argumentation, and that (ii) it is impossible to make general statements about the defectiveness of an argumentation that exhibits these features. Such an argumentation, in contrast, has to be evaluated on a case-by-case basis. “Petitio principii”, this paper thence suggests, is one name for, in fact, a multitude of different and quite complex dialectical situations which require specific analysis and evaluation.     

Patients’ Perceptions of Risky Developments During Psychotherapy

Research on risks and unwanted effects is largely missing in psychotherapy. Using exploratory factor analysis six dimensions of personal therapy situation were identified in a preliminary study, three of them were associated with risky developments during the psychotherapeutic process: (1) (poor) quality of therapeutic relationship, (2) burden caused by psychotherapy, and (3) dependency/isolation. Based on the finding of this study an online survey was performed to examine these three dimensions. Aside from these three factors another variable was associated with risky therapy developments: the online questionnaire also asked for premature terminations of psychotherapy as a consequence of risky conditions for the therapeutic development. Risky conditions were found to be associated with the following variables: (1) the combination of female patient–male therapist, (2) the therapeutic orientation (particularly with the psychodynamic approaches) and (3) the duration of therapy. Fewer humanistic and systemic psychotherapies were found among the high risk-prone group of patients who were at risk in at least three of the four variables which were associated with risky developments. Differences in the findings of the study regarding the four therapeutic orientations stress the importance of an extensive differential indication and a cooperative partnership between patient and therapist, in order to facilitate a positive patient participation towards the choice of therapy method and subsequent successful participation throughout the course of treatment. Further studies should also focus on female patient and male therapist psychotherapies.     

Recognition of facial affect in Borderline Personality Disorder

Patients with Borderline Personality Disorder (BPD) have been described as emotionally hyperresponsive, especially to anger and fear in social contexts. The aim was to investigate whether BPD patients are more sensitive but less accurate in terms of basic emotion recognition, and show a bias towards perceiving anger and fear when evaluating ambiguous facial expressions. Twenty-five women with BPD were compared with healthy controls on two different facial emotion recognition tasks. The first task allowed the assessment of the subjective detection threshold as well as the number of evaluation errors on six basic emotions. The second task assessed a response bias to blends of basic emotions. BPD patients showed no general deficit on the affect recognition task, but did show enhanced learning over the course of the experiment. For ambiguous emotional stimuli, we found a bias towards the perception of anger in the BPD patients but not towards fear. BPD patients are accurate in perceiving facial emotions, and are probably more sensitive to familiar facial expressions. They show a bias towards perceiving anger, when socio-affective cues are ambiguous. Interpersonal training should focus on the differentiation of ambiguous emotion in order to reduce a biased appraisal of others.
