The paper offers a solution to the semantic paradoxes, one in which (1) we keep the unrestricted truth schema True(A)A, and (2) the object language can include its own metalanguage. Because of the first feature, classical logic must be restricted, but full classical reasoning applies in ordinary contexts, including standard set theory. The more general logic that replaces classical logic includes a principle of substitutivity of equivalents, which with the truth schema leads to the general intersubstitutivity of True(A) with A within the language.The logic is also shown to have the resources required to represent the way in which sentences (like the Liar sentence and the Curry sentence) that lead to paradox in classical logic are defective. We can in fact define a hierarchy of defectiveness predicates within the language. Contrary to claims that any solution to the paradoxes just breeds further paradoxes (revenge problems) involving defectiveness predicates, there is a general consistency/conservativeness proof that shows that talk of truth and the various levels of defectiveness can all be made coherent together within a single object language.  相似文献

The main purpose of the paper is to introduce philosophers and philosophical logicians to dynamic logic, a subject which promises to be of interest also to philosophy. A new completeness result involving both after — and during — operators is announced.The work on this paper was supported in part by an Academy of Finland fellowship för längre hunna vetenskapsidkare during the former half of 1979. The paper itself was read as an invited address at the Conference on Practical and Philosophical Motivations of Non-classical Logics held at Toru, August 15–19, 1979.  相似文献

The dialogical games introduced in Jaakko Hintikka, Information-Seeking Dialogues: A Model, (Erkenntnis, vol. 14, 1979) are studied here to answer the question as to what the natural logic or the logic of natural language is. In a natural language certain epistemic elements are not explicitly indicated, but they determine which inference rules are valid. By means of dialogical games, the question is answered: all classical first-order rules have to be modified in the same way in which some of them are modified in the transition to intuitionistic logic. (Furthermore, in some cases quantificational rules have to be modified further.) The rules that are left unmodified by intuitionists are applicable only to the output of certain game rules, but not to others. In. this sense, neither classical nor yet intuitionistic logic is the logic of natural language. We need a new type of nonclassical logic, justified by our information-seeking dialogues.  相似文献

Separate factor analyses of the value rankings of 53 male and 77 female college students yielded three factors for each gender. Interpretation suggested Creative Self-Determination versus Submissive Dependency, Personal Gratification versus Sociopolitical Consciousness, and Existential Responsibility versus Traditionalism as core concepts for the female respondents; while males' axiological dimensions were labeled Communal Idealism versus Entrepreneural Pragmatism, Hedonism versus Egalitarianism, and Sybaritic Bohemianism versus Traditional Sobriety. Each pole of the female factors was interpreted as reflecting a major ideological referent component of the Women's Liberation Movement, while male factors were construed as constituting perspectives for interpreting varieties of response to feminist ideology. Techniques for increasing individuals' levels of self-actualization by direct intervention in axiological organization were discussed.  相似文献

In an effort to explore how group therapists can apply psychoanalytic theory in the group modality to advantage, two major developments in analytic theory are examined. 1) Kernberg stresses the neutral interpretive stance and utilizes concepts of protective identification and splitting in dealing with borderline pathology. This paper illustrates concretely how such theory can be used by the group therapist to encourage working through in the group situation. 2) Kohut's work stresses the empathic, nurturant analytic stance and focuses upon idealization, the grandiose self and the self-object. An understanding of these concepts helps the group therapist avoid obstacles in the treatment of narcissistic patients and can enrich the therapeutic work. The paper concludes that treatment of the difficult patient may be enhanced by the group situation in combination with specific psychoanalytic concepts.  相似文献

The semantical structures called T×W frames were introduced in (Thomason, 1984) for the Ockhamist temporal-modal language, O, which consists of the usual propositional language augmented with the Priorean operators P and F and with a possibility operator . However, these structures are also suitable for interpreting an extended language, SO, containing a further possibility operator s which expresses synchronism among possibly incompatible histories and which can thus be thought of as a cross-history simultaneity operator. In the present paper we provide an infinite set of axioms in SO, which is shown to be strongly complete forT ×W-validity. Von Kutschera (1997) contains a finite axiomatization of T×W-validity which however makes use of the Gabbay Irreflexivity Rule (Gabbay, 1981). In order to avoid using this rule, the proof presented here develops a new technique to deal with reflexive maximal consistent sets in Henkin-style constructions.  相似文献

a–b* c–d is taken to mean that your degree of preference for a over b is less than your degree of preference for c over d. Various properties of the strength-of-preference comparison relation * are examined along with properties of simple preferences defined from *. The investigation recognizes an individual's limited ability to make precise judgments. Several utility theorems relating a–b * c–d to u(a)–u(b) are included.  相似文献

Let g E(m, n)=o mean that n is the Gödel-number of the shortest derivation from E of an equation of the form (m)=k. Hao Wang suggests that the condition for general recursiveness mn(g E(m, n)=o) can be proved constructively if one can find a speedfunction s s, with s(m) bounding the number of steps for getting a value of (m), such that mn s(m) s.t. g E(m, n)=o. This idea, he thinks, yields a constructivist notion of an effectively computable function, one that doesn't get us into a vicious circle since we intuitively know, to begin with, that certain proofs are constructive and certain functions effectively computable. This paper gives a broad possibility proof for the existence of such classes of effectively computable functions, with Wang's idea of effective computability generalized along a number of dimensions.We are grateful to an anonymous referee for Studia Logica for valuable advice leading to substantial improvements in the presentation of the main definitions and theorem.  相似文献

This article explores the cross-cultural implications of the Western notion of boundaries and the Asian matrix of relationality for pastoral care ministry. Theorists of codependence (relationship addiction) show that American awareness of boundaries produces phobic attitudes toward the interwoven interplay of human relationships. Noting the underlying American cultural ideal (i.e., individual autonomy), evidences that boundaries are culturally defined are reviewed. Drawing upon the social-psychological concept of interdependence (Asian construal of self), the author proposes that there is a need for a different understanding of boundaries, since some Asian people have strikingly different construals of the self, of others, and of the interdependence of the two. Boundaries and relationality need to be in dialogue with each other so as to create relational boundaries that empower mutual relations within which we may come to experience the power of the relational, triune God.  相似文献

Sigmund Freud's concept of the Uncanny can serve as a means by which we can more fully comprehend the depth of our individual and collective reactions to the tragic eventsof September 11th. Through the interplay of the familiar and the unfamiliar, life and death, as well as through the concepts of the twin, repetition, and the evil but powerful figure, Freud helps us to understand how deeply this day in our history made signficant inroads into our psyche. The person of faith, in turn, can utilize these concepts to help with the hermeneutical process of making sense of what otherwise cannot be fathomed.  相似文献

The aim of this note is to show (Theorem 1.6) that in each of the cases: = {, }, or {, , }, or {, , } there are uncountably many -intermediate logics which are not finitely approximable. This result together with the results known in literature allow us to conclude (Theorem 2.2) that for each : either all -intermediate logics are finitely approximate or there are uncountably many of them which lack the property.  相似文献

The therapist's work in a public outpatient clinic is a unique combination as an individual and as a team member. Although the therapist may enjoy working within a team framework, sharing common goals and providing support and supervision, when he feels this environment failing to help or becoming critical, he may begin to experience loneliness. Individual psychotherapy occasionally evinces feelings of loneliness. The therapist has to contend with his patient's powerful feelings and try to contain them. We examined issues of loneliness, teamwork, and burnout during open meetings with the staff of three outpatient clinics. In addition, 50 questionnaires were sent to the therapists. Thirty-one were answered anonymously. Most of the therapists (80%) reported interest and enjoyment in their work with only 15% reporting tension and feelings of burnout. In the Pearson statistic correlation, there was a significant relationship between satisfaction at work and the lack of loneliness (p < 0.01). There was an inverse statistical correlation between satisfaction and burnout (p < 0.01) and a connection between staff meetings and not feeling lonely (p < 0.05). We found that the therapist in the outpatient clinic does not feel lonely. The staff meetings and consultations support him as a team member. A disparity was found between feelings felt at the open meetings and those in the questionnaires. Although the therapist is satisfied with his work, problems of overload and the danger of burnout are always present. It should be noted that clinic administrators should pay close attention to the entire picture.  相似文献

This essay considers the recuperation of beauty as a productive critical strategy in discussions of African American dance. I argue that black performance in general, and African American concert dance in particular, seeks to create aesthetic sites that allow black Americans to participate in discourses of recognition and appreciation to include concepts of beauty. In this, I suggest that beauty may indeed produce social change for its attendant audiences. I also propose that interrogating the notion of beauty may allow for social change among audiences that include dance theorists and philosophers. Through a case-study consideration of work by three African American choreographers, Donald Byrd (b. 1949), Ulysses Dove (1947 – 1996), and Abdel Salaam (b. 1949), I ultimately hope to suggest critical possibilities aligning dance performance with particular aesthetic theory relevant to its documentation and interpretation.  相似文献

Guttman's index of indeterminacy (22 – 1) measures the potential amount of uncertainty in picking the right alternative interpretation for a factor. When alternative solutions for a factor are equally likely to be correct, then the squared multiple correlation 2 for predicting the factor from the observed variables is the average correlation AB between independently selected alternative solutionsA andB, while var ( AB )=(1 – 2)2/s, wheres is the dimensionality of the space in which unpredicted components of alternative solutions are to be found. When alternative solutions for the factor are not equally likely to be chosen, 2 is the lower bound for E( AB ); however, E( AB ) need not be a modal value in the distribution of AB . Guttman's index and E( AB ) measure different aspects of the same indeterminacy problem.  相似文献

This paper addresses the importance of the concept of ideology in community work. The implications of a Marxist approach to ideology in community practice are analyzed in terms of the concepts of problematization (P. Freire, 1979) and consciousness-raising (J. Barreiro, 1976), illustrating the point with some examples. The traditional Marxist perspective is also examined in relation to the perspectives of social constructionism (I. Ibáñez, 1996), cultural studies (A. McRobbie, 1992), post-Marxism (E. Laclau & C. Mouffe, 1985), and feminism (D. Haraway, 1991). It is argued that the concepts of hegemony and habitus (P. Bourdieu, 1985) can be useful to community social psychology theory and practice. A situated perspective—in which it is possible to dialogue from different subject positions, and articulate transformation and political action—is argued. The implications of this shifting in the concept of ideology by means of theoretical developments outside social community psychology can help to define the external (outside) agent's position in community practice.  相似文献

In this article we show how the universe of HST, Hrbaek set theory (a nonstandard set theory of external type, which includes, in particular, the ZFC Replacement and Separation schemata for all formulas in the language containing the membership and standardness predicates, and Saturation for standard size families of internal sets, but does not include the Power set axiom) admits a system of subuniverses which keep the Replacement, model Power set and Choice (in fact all of ZFC, with the exception of the Regularity axiom, which indeed is replaced by the Regularity over the internal subuniverse), and also keep as much of Saturation as it is necessary.This gives sufficient tools to develop the most complicated topics in nonstandard analysis, such as Loeb measures.Partially supported by AMS grants in 1993 – 1995 and DFG grants in 1994 – 1995.

This study examined the comprehension by children of the concepts of order, duration, and simultaneity as reflected in certain linguistic structures. The children in the study were 3, 5, and 7 years old. Temporal order was examined through children's comprehension of two-clause sentences containing the conjunctions after, before, since, and until. Temporal duration was examined through children's understanding of one-clause sentences containing the progressive aspect and two-clause sentences containing the conjunctions since and until. These two conjunctions signal duration in the main clause when they conjoin two clauses. Simultaneity was studied through children's comprehension of two-clause sentences containing while. The results revealed that the order sentence structures (before and after) were generally comprehended by the children before the duration or simultaneous sentence structures, although at 7 years of age children were still not performing above chance on the order relation in since and until sentences. The duration sentence structures were comprehended by the children before the simultaneous sentence structures. The results support the literature in cognitive psychology and in philosophy which argues that order is simpler than duration is simpler than simultaneity.This report is based on a dissertation submitted to the University of Michigan in partial fulfillment of the requirement for the Ph.D.  相似文献

Conclusion In conclusion, I have tried to show that if there are any rights at all, legal, moral and political, there are at least the sorts of human rights cited in the Universal Declaration, rights which extend beyond the slender base provided by Hart's right to be free and which include the right to an adequate human life for everyone, rights shared by all, rights that, as rights, imply correlative duties. Even though the duties thus implied are admittedly imperfect, as rights, they confer upon right-holders, the authority to obligate others.I have argued for the most part against regarding any rights, even some human, rights (interchangable here with manifesto rights, welfare rights, rights of recipience, social and economic rights, programme rights, Fawcett calls them, positive in rem rights) as claims to rights or proposals for adoption as rights. I have argued that to have a right of any kind, including especially a human right, one shared by and held equally by all human beings,while not unconditional or unalterable, is fundamentally important, - to return once again to Feinberg's definition at the opening of this paper. A human right is fundamentally important, however, only if it, too, implies an obligation on the part of other people, one in which other people are obligated to use their power and resources to make things happen. To havea right is to be in a position to impose corresponding obligations on others. As Kant pointed out, a right of any kind gives a right holder a title to compel.

This study investigated managerial stress in Taiwan and UK using the Occupational Stress Indicator-2 (OSI-2) and the Work Locus of Control (WLCS) scale. Results showed that the reliability and validity of the measures used were acceptable and comparable in the two samples. There were similarities as well as differences in managerial stress in the two countries. Recognition and Managerial role were important predictors of strain for the Chinese managers, whereas Relationships, Organizational climate, and Personal responsibility were important predictors of strain for UK managers. There were consistent moderating (vulnerability) effects of internal control for the Taiwanese managers. Results corroborated some previous studies conducted in the West. However, caution was also suggested for generalizing Western-originated concepts and theories across cultural boundaries.  相似文献

Both Nietzsche and Merleau-Ponty repudiate the mirror view of perception and embrace what Nietzsche refers to as solar love or creative perception. I argue that Merleau-Ponty thinks of this type of perception primarily in terms of convergence and Nietzsche in terms of divergence. I then show how, contrary to their own emphases, Merleau-Ponty's notion of flesh and Nietzsche's idea of chaos suggest that convergence and divergence are abstractions from an ontologically prior realm of hybrid perceptions. In this realm, each perception is shot through with the others, simultaneously inside and outside one another. The creative tension among these perceptions continually produces new perspectives or voices, that is, a realm whose very being is metamorphosis. Moreover, this realm of hybrid perceptions suggests a political principle that might prove attractive for communities in an age of diversity and cultural hybridity.  相似文献
