Traditional Logic,Modern Logic and Natural Language

In a recent paper Johan van Benthem reviews earlier work done by himself and colleagues on ‘natural logic’. His paper makes a number of challenging comments on the relationships between traditional logic, modern logic and natural logic. I respond to his challenge, by drawing what I think are the most significant lines dividing traditional logic from modern. The leading difference is in the way logic is expected to be used for checking arguments. For traditionals the checking is local, i.e. separately for each inference step. Between inference steps, several kinds of paraphrasing are allowed. Today we formalise globally: we choose a symbolisation that works for the entire argument, and thus we eliminate intuitive steps and changes of viewpoint during the argument. Frege and Peano recast the logical rules so as to make this possible. I comment also on the traditional assumption that logical processing takes place at the top syntactic level, and I question Johan’s view that natural logic is ‘natural’.     

Solution-focused Couples Therapy Groups: An Empirical Study

The professional literature contains numerous theoretical and case study articles regarding the development and use of solution-focused therapy. However, as with many models of systems-oriented therapy in use with couples, very little has been subjected to empirical investigation. This project was designed to make a contribution to the empirical literature regarding the effectiveness of solution-focused therapy in use with couples' groups. This study utilized pre-test comparisons of treatment and comparison groups, and examined pre- to post-test changes in the scores of the treatment group couples. Twenty-three treatment group couples participated in a six-week solution-focused couples therapy (SFCT) group. A separate group of thirteen couples served as a comparison group. The Dyadic Adjustment Scale (DAS) was used to assess changes in the couples' relationships. Scores on the Marital Status Inventory (MSI), as a pre-test measure indicating the couples' likelihood of divorce, indicated no significant differences between groups. The remaining analyses revealed significant improvement in DAS scores. Self-reports from the couples involved indicate improvement in a variety of areas after completing the six-week solution-focused couples group therapy process.     

Spirituality and religion in training, practice and personal development

In the midst of a revitalized interest in spirituality and religion in Western societies, there has been reported a resurgence of activity regarding spirituality and religion in the mental health professions, including marriage and family therapy (MFT). Little is known, however, about the beliefs, behaviours, and training experiences of MFT graduate students. Therefore it is important to examine the training (education and supervision) needs in this area. For this initial study, a sample of US MFT graduate students were surveyed regarding their spiritual and religious attitudes and practices in their personal and professional lives. In most areas, graduate students were found to be similar to the previously published reports of practising professionals. In other areas, they report even more investment in spirituality and religion. The results of the survey suggest a need to include systematic attention to these areas in graduate training curricula and in the professional supervision process.     

Dialogue protocols for formal fallacies: A reply to Kacprzak and Yaskorska

This note comments on the paper ‘Dialogue protocols for formal fallacies’ by Kacprzak and Yaskorska (this issue). Points discussed include the use of the notions of ‘claiming’, ‘conceding’ and ‘commitment’, and the role of Lorenzen dialogues as a device for checking whether a proposition is a tautology.
