Possibilities,models, and intuitionistic logic: Ian Rumfitt’s The boundary stones of thought

AIan Rumfitt's new book presents a distinctive and intriguing philosophy of logic, one that ultimately settles on classical logic as the uniquely correct one–or at least rebuts some prominent arguments against classical logic. The purpose of this note is to evaluate Rumfitt's perspective by focusing on some themes that have occupied me for some time: (i) the role and importance of model theory and, in particular, the place of counter-arguments in establishing invalidity, (ii) higher-order logic, and (iii) the logical pluralism/relativism articulated in my own recent *Varieties of logic*.     

Connotative Meaning as a Determinant of Response to Test Item Content

The purpose of this study was to determine if responses of like or dislike to Perceptual Reaction Test (PRT) designs — and thus, its ability to discriminate among criterion groups — were related to the connotative meaning of the designs. Seventy-four Ss were administered the PRT designs to which they responded on the traditional like-dislike alternatives as well as rating each design on a semantic differential. Correlations between the like-dislike dimension of the PRT designs and the semantic differential ratings of those designs indicated that when a S checks like for a design, he is expressing a positive evaluation of that design and probably sees it as less potent than those designs for which he checked dislike. Expression of like or dislike for a design appears to be inconsistently related to the activity dimension of meaning.     

On the Existential Interpretation of the Rorschach Test

This is an analysis of the Rorschachs of two subjects, a boy and a girl, from the longitudinal research programs of the Institute of Human Development, University of California, Berkeley. Rorschachs had been obtained from these subjects prior to their becoming seriously ill, one with a kidney condition, the other with leukemia. On the basis of the thematic content of the Rorschachs, it was postulated that Rorschach responses may, like dreams, be considered endoscopic in that they may reveal the actual functioning or disfunctioning of the organism, particularly at the onset of somatic illness. Data, from anthropological, mythological, and literary sources, as well as research on the body image concept, were utilized to amplify the hypothesis and to suggest directions for further research.

A Note on Change in Creativity by Handedness Over A Maturational Time Period

Thirty left-handed and right-handed Ss (10 each from the second grade, fifth grade, and college) were compared on four subtests of the Torrance creativity test. At each age level, left-handed students had higher creativity scores than right-handers. The greatest differences were found on the Elaboration subtest.     

Measuring Responsiveness in the Therapeutic Relationship: A Patient Perspective

This article reports results from a three-country study of patient perceptions of physician responsiveness. Based on existing research in the medical and social-psychological literatures, we theorized that patients' perceptions of physician responsiveness to their needs would be an important component of the patient–physician relationship and that this construct could be distinguished reliably from more global assessments of patient satisfaction. We then developed a new measure designed to assess these perceptions from the patients' point of view. This measure was administered to large samples of patients in the United States, the United Kingdom, and Canada. Results supported our hypotheses. Patient perception of physician responsiveness significantly predicted both patient satisfaction and subjective health-related problems, over and above effects attributable to general satisfaction. We also noted the absence of significant differences across the three cultures or sex, suggesting that the process we identify has considerable generality. We also describe a short version of our measure that researchers may find useful in a variety of research or clinical settings.     

Remarks on the development of computability

The purpose of this article is to examine aspects of the development of the concept and theory of computability through the theory of recursive functions. Following a brief introduction, Section 2 is devoted to the presuppositions of computability. It focuses on certain concepts, beliefs and theorems necessary for a general property of computability to be formulated and developed into a mathematical theory. The following two sections concern situations in which the presuppositions were realized and the theory of computability was developed. It is suggested in Section 3 that a central item was the problem of generalizing Gödel's incompleteness theorem. It is shown that this involved both the characterization of recursiveness and the attempt to clarify and formulate the notion of an effective process as it relates to the syntax of deductive systems. Section 4 concerns the decision problems which grew from the Hilbert program. Section 5 is devoted to the development of an informal' technique in the theory of computability often called ‘argument by Church's thesis’.     

A Debate About Anderson's Logic

This article is about the history of logic in Australia. Douglas Gasking (1911–1994) undertook to translate the logical terminology of John Anderson (1893–1962) into that of Ludwig Wittgenstein's (1921) Tractatus. At the time Gilbert Ryle (1900–1976), and more recently David Armstrong, recommended the result to students; but it is reasonable to have misgivings about Gasking as a guide to either Anderson or Wittgenstein. The historical interest of the debate Gasking initiated is that it yielded surprisingly little information about Anderson's traditional (syllogistic or Aristotelian) logic and its relation to classical (first-order predicate or Russellian) logic, the ostensible topic; but the materials now exist to interpret Anderson's logic in classical logic, possibly as an algebra of classes. This would be of little interest to contemporary logicians, but it might shed some light on Anderson's philosophy.     

Valedictory

Contingentism, generally contrasted with law necessitarianism, is the view that the laws of nature are contingent. It is often coupled with the claim that their contingency is knowable a priori. This paper considers Bird's [2001 Bird, Alexander 2001. Necessarily, Salt Dissolves In Water, Analysis 61/4: 267–74.[Crossref], [Web of Science ®] , [Google Scholar], 2002 Bird, Alexander 2002. On Whether Some Laws Are Necessary, Analysis 62/3: 257–70.[Crossref], [Web of Science ®] , [Google Scholar], 2005 Bird, Alexander 2005. Unexpected A Posteriori Necessary Laws of Nature, Australasian Journal of Philosophy 83/4: 533–48.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar], 2007 Bird, Alexander 2007. Nature's Metaphysics: Laws and Properties, Oxford: Clarendon Press.[Crossref] , [Google Scholar]] arguments for the thesis that, necessarily, salt dissolves in water; and it defends his view against Beebee's [2001] and Psillos's [2002 Psillos, Stathis 2002. Salt Does Dissolve In Water, But Not Necessarily, Analysis 62/3: 255–7.[Crossref], [Web of Science ®] , [Google Scholar]] contingentist objections. A new contingentist objection is offered and several reasons for scepticism about its success are raised. It is concluded that certain higher-level laws describing the behaviours of molecular compounds may be necessary due to their dependence on underlying physical laws, and that the modal status of laws of nature cannot be determined a priori, as the structural features of the substances and properties they govern must first be investigated.     

Personal goals as predictors of intended classroom goals: Comparing elementary and secondary school pre‐service teachers

Background and Aims. The literature documents fewer classroom mastery goal structures in secondary school compared to elementary. However, little is known about how personal achievement goals may influence classroom goal structures. This is especially true at the level of pre‐service teachers. Our objective was to investigate if pre‐service teachers’ personal goals predicted their intended classroom goal structures. Sample. Participants were 125 elementary and 175 secondary school pre‐service teachers from two Western Canadian universities. Method. Structural equation modelling was used to examine if the structural relationships and latent means of personal and intended classroom goal structures differed for elementary and secondary school pre‐service teachers. Results. The results revealed that personal goals predicted the goal structures that pre‐service teachers intended to establish; however, the relationships and means differed between elementary and secondary school pre‐service teachers. Specifically, personal mastery‐approach goals positively predicted classroom mastery goals much more strongly at the elementary than the secondary level. Furthermore, elementary pre‐service teachers had significantly higher latent mean scores on personal mastery‐approach goals than their secondary counterparts. Conclusions. It seems possible that the currently documented differences between classroom goal structures noted for elementary compared to secondary school may be based on the personal goals endorsed as pre‐service teachers. The results are further discussed in terms of alignment with research on practising teachers’ personal and classroom goals and implications for teacher education.
