José M. Méndez Systems with the converse Ackermann property
abstract | view |  rights & permissions
A system S has the “converse Ackermann property” (C.A.P.) if (A -> B) -> C is unprovable in S whenever C is a propositional variable. In this paper we define the fragments with the C.A.P. of some well-know propositional systems in the spectrum between the minimal and classical logic. In the first part we succesively study the implicative and positive fragments and the full calculi. In the second, we prove by a matrix method that each one of the systems has the C.A.P. Thus, we think the problem proposed in Anderson & Belnap (1975) § 8.12 has been solved.

Ubiratan D’Ambrosio A Methodology for Ethnoscience: the Need for Alternative Epistemologies
abstract | view |  rights & permissions
In this paper it is assumed a broad conceptualization of Science which allows far looking into common practices which are apparently unstructured forms of knowledge. This result from a concept of culture which is the result of an hierarchization of behavior. In this theoretical framewark the concept of ethnoscience is analysed.

José M. Sanchez-Ron Physics and Philosophy: Action at a Distance in 20th Century Physics
abstract | view |  rights & permissions
In this paper I review the different opinions held by scientists and philosophers as regards the status of the action-at-a-distance concept within relativistic physics. It is shown that in spite of the fact that the prevailing opinion has been that special relativity precludes actions at a distance, some important physicists have continued employing that concept throughout the present century. The key to understand that “anomalous” behaviour lies, in fact, in the relationships existent between quantum and classical physics (“inverse” principle of correspondence).

Jerzy Wroblewski Problems of Ontological Complexity of Law
abstract | view |  rights & permissions
There are five basic types of ontology of law identified in relation with the singling out simpIe ontological objects in a strong or weak sense, dualist ontological objects, and complex ontalogical objects in a strong or weak sense. The conceptians of law far mulated in the theories/philosophies/ of law are ascribed to these five types.

Sanchez de Zavala Towards a less simple butsounder(psychological) Pragmatics I
abstract | view |  rights & permissions
Both as regards their compass (non-other-addressed speech and non-informative communication are in effect ignored) and their scarcely empirical nature, there is reason to be dissatisfied with recent developments in Pragmatics. How to find a sounder basis for pragmatic investigation? If a psychological (in this sense: centered on underlying mental processes) appproach is adopted in Pragmatics investigation, a strategic detour through mental processes leading to other kinds of activities is likely to prove methodologically sound and heuristically fruitful. For it allows outlining an abstract model of (mental processes) inception of any kind of activity, keeping so at bay theoretical bias from the particular pragmatic standpoint that the theorist may happen to favor. And filling in the model with the specific features of language use shows promise to provide more specific models of the psychological processes underlying performance of linguistic activities.

Víctor Sanchez de Zavala Towards a less simple but sounder (psychological) Pragmatics II
abstract | view |  rights & permissions
This paper addresses first the appticability of the main notions included in the general notion meant item, meant partial situation (MPST), meant activity (MACT), and implicitly meant background situation (IMBST) -that of meant agent will be only mentioned in an aside-, plus the notion meaning activity (MNGACT). It will be shown that, when coupled to other notions, such as ‘ontological status’ of IMBST relative to the focussed (part of) current situation (FCST), as well as to the matching ‘ontological’ properties of the meant items above, they allow to set up unified and apparently successful methods to explore important and debated pragmatic issues. Then their usefulness for research in the domain traditionally accorded to speech-act theory is put to (a preliminary) test; and finally the general processual sketch of linguistic activity advanced in the last Sections of P.I is carefully gauged as to its prospects regarding actual implementation of more specific processual sketches of both emission and reception linguistic activities.
