Which of the fallacies are fallacies of relevance?

This paper looks around among the major traditional fallacies — centering mainly around the so-called gang of eighteen — to discuss which of them should properly be classified as fallacies of relevance. The paper argues that four of these fallacies are fallacies primarily because they are failures of relevance in argumentation, while others are fallacies in a way that is more peripherally related to failures of relevance. Still others have an even more tangential relation to failures of relevance. This paper is part of a larger research project on dialecical relevance in argumentative discourse, currently underway in collaboration with Frans van Eemeren and Rob Grootendorst.     

Why Logic Doesn‘t Matter in the (Philosophical) Study of Argumentation

Philosophically, the study of argumentation is important because it holds out the prospect of an interpretation of rationality. For this we need to identify a transcendent perspective on the argumentative interaction. We need a normative theory of argumentation that provides an answer to the question: should the hearer accept the argument of the speaker. In this article I argue that formal logic implies a notion of transcendence that is not suitable for the study of argumentation, because, from a logical point of view, argumentation disappears from sight. We should therefore not expect formal logic to provide an interesting interpretation of the rationality intrinsic in argument and discussion.     

Towards a Rough Mereology-Based Logic for Approximate Solution Synthesis. Part 1

We are concerned with formal models of reasoning under uncertainty. Many approaches to this problem are known in the literature e.g. Dempster-Shafer theory [29], [42], bayesian-based reasoning [21], [29], belief networks [29], many-valued logics and fuzzy logics [6], non-monotonic logics [29], neural network logics [14]. We propose rough mereology developed by the last two authors [22-25] as a foundation for approximate reasoning about complex objects. Our notion of a complex object includes, among others, proofs understood as schemes constructed in order to support within our knowledge assertions/hypotheses about reality described by our knowledge incompletely.     

Hoisted by their own petards: Philosophical positions that self-destruct

Philosophers have not resisted temptation to transgress against the logic of their own conceptual structures. Self-undermining position-taking is an occupational hazard. Philosophy stands in need of conceptual therapy.The author describes three conceptions of philosophy: the narcissistic, disputatious, and therapeutic. (i) Narcissistic philosophy is hermetic, believing itself to contain all evidence that can possibly be relevant to it. Philosophy undertaken in this spirit has led to defensive, monadically isolated positions. (ii) Disputatious philosophies are fundamentally question-begging, animated by assumptions that philosophical adversaries reject. (iii) The intention of therapeutic philosophy is to study philosophical positions from the standpoint of their internal consistency, or lack of it. In particular, its interest is in positions that either compel assent, because they cannot be rejected without self-referential inconsistency, or self-destruct because self-referential inconsistency cannot be avoided. The article's focus is on the latter. Several examples of self-undermining positions are drawn from the history of philosophy, exemplifying two main varieties of self-referential inconsistency: pragmatical and projective.     

The disputation — a special type of cooperative argumentative dialogue

This article consists of three parts, two introductory, in which the limits and the methods of analysis of dialogues are expounded, and the major part, in which the main features of a philosophical theory of disputation are outlined.

A “new rhetoric” for a “new dialectic”: Prolegomena to a responsible public argument

This essay offers, as a counterpart to pragma-dialectical argument, a “new rhetoric” produced in the situated discourse of a public forum when a community addresses matters of common urgency and undertakes informed action. Such a rhetoric takes the principles of discourse ethics as its informing dialectic by identifying an interlocutor as one who is obligatedboth to argue effectively,and also to hold open, even reinforce, norms of communicative reason. Implications concerning the study of fallacies and theethos obligations of communicative reasoning are discussed.     

From biography to theory: the role of Anna Freud in the emergence of the ‘adolescent process’

Some aspects of Anna Freud’s life reveal the existence of specifically adolescent conflicts, which can be tied to some of her theoretical and clinical discoveries in the field of adolescent psychoanalysis. Her historical input in the gradual construction of a theoretical corpus on adolescence has often been ignored. These links between biography and theory gave rise to a movement of conceptualisation, making it possible to develop a psychoanalytic metapsychology of adolescence: indeed, emerged such notions as asceticism, intellectualisation in relationship with anorexia and the struggle against the genitalisation of the adolescent body. Today, the Annafreudian school of thought has remained the main source of investigation and theoretical transmission of what is now called the adolescent process.     

The Traumatic Grief Inventory Self-Report Version (TGI-SR): Introduction and Preliminary Psychometric Evaluation

Persistent Complex Bereavement Disorder (PCBD) is a disorder of grief newly included in the “Emerging Measures and Models” section of the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; American Psychiatric Association, 2013 American Psychiatric Association. (2013). Diagnostic and statistical manual of mental disorders (5th ed.). Washington, DC: Author. [Google Scholar]). Prolonged Grief Disorder (PGD) is a disorder with similar symptoms, likely to be included in the forthcoming 11th edition of the International Classification of Diseases (ICD-11; World Health Organization, 1992 World Health Organization. (1992). International classification of diseases and related health problems (10th revision). Geneva, Switzerland: World Health Organization. [Google Scholar]). We developed the Traumatic Grief Inventory Self-Report version (TGI-SR), an 18-item measure, for the assessment of symptoms of PCBD and PGD in clinical and research settings. This study was an initial attempt to evaluate psychometric properties of the TGI-SR. To this end, the measure was administered to 327 patients of a mental health institute specialized in the treatment of psychopathology associated with loss and trauma. We found evidence that items of the TGI-SR (all 18 items, as well as the selection of 17 items representing PCBD criteria, and 11 items representing PGD criteria) loaded on one dimension. The TGI-SR demonstrated strong internal consistency. Elevated scores on the TGI-SR were significantly correlated with elevated scores on indices of psychopathology and lower quality of life, attesting to the concurrent validity. Receiver operation characteristic (ROC) analyses of the TGI-SR total score against provisional diagnoses of PCBD and PGD yielded a high area under the curve index suggesting that the TGI-SR total score can be used as an indicator for probable diagnoses of both PCBD and PGD. Results of this study provide initial evidence that PCBD and PGD symptoms may be readily and reliably measured using the TGI-SR.
