It is argued that the distinction between the normative and the descriptive interpretation of norm sentences can be regarded as a distinction between two kinds of utterances. A norm or a directive has as its content a normative proposition. A normative utterance of a normative proposition in appropriate circumstances makes the proposition true, and an assertive utterance has as its truth-maker the norm system to which it refers. This account of norms, norm-contents, and utterances of norm sentences solves Jørgensen's problem: (...) logical relations among norms can be defined in the usual way in terms of the truth-conditions of the normative propositions which form their content. There is no distinction between the logic of norms and the logic of normative propositions; in this respect the present account differs from Carlos Alchourrón and Eugenio Bulygin's account of the logic of normative propositions. Se argumenta que la distinción entre la interpretación normativa y la descriptiva de las oraciones normativas puede ser considerada como una distinción entre dos tipos de emisiones. Una norma o directiva tiene como su contenido una proposición normativa. Una emisión normativa de una proposición normativa en circunstancias apropiadas hace verdadera la proposición y es el sistema de normas al que se refiere una emisión asertiva el que la hace verdadera. Esta concepción de normas, contenidos de normas y emisiones de oraciones normativas resuelve el problema de Jörgensen: las relaciones lógicas entre normas pueden ser definidas de manera usual en términos de las condiciones de verdad de las proposiciones normativas que forman su contenido. No hay diferencia alguna entre la lógica de normas y la lógica de proposiciones normativas; en este aspecto la presente concepción difiere de la concepción de la lógica de proposiciones normativas de Carlos Alchourrón y Eugenio Bulygin.

A distributed neural network model called SPEC for processing sentences with recursive relative clauses is described. The model is based on separating the tasks of segmenting the input word sequence into clauses, forming the case‐role representations, and keeping track of the recursive embeddings into different modules. The system needs to be trained only with the basic sentence constructs, and it generalizes not only to new instances of familiar relative clause structures but to novel structures as well. SPEC exhibits plausible memory (...) degradation as the depth of the center embeddings increases, its memory is primed by earlier constituents, and its performance is aided by semantic constraints between the constituents. The ability to process structure is largely due to a central executive network that monitors and controls the execution of the entire system. This way, in contrast to earlier subsymbolic systems, parsing is modeled as a controlled high‐level process rather than one based on automatic reflex responses. (shrink)

One of the characteristic features of contemporary logic is that it incorporates the Frege‐Russell thesis according to which verbs for being are multiply ambiguous. This thesis was not accepted before the nineteenth century. In Aristotle existence could not serve alone as a predicate term. However, it could be a part of the force of the predicate term, depending on the context. For Kant existence could not even be a part of the force of the predicate term. Hence, after Kant, existence (...) was left homeless. It found a home in the algebra of logic in which the operators corresponding to universal and particular judgments were treated as duals, and universal judgments were taken to be relative to some universe of discourse. Because of the duality, existential quantifier expressions came to express existence. The orphaned notion of existence thus found a new home in the existential quantifier. (shrink)

The present volume is a sequel to Deontic Logic: Introductory and Systematic Readings : its purpose is to offer a view of some of the main directions of research in contemporary deontic logic. Most of the articles included in Introductory and Systematic Readings represent what may be called the standard modal approach to deontic logic, in which de on tic logic is treated as a branch of modal logic, and the normative concepts of obligation, permission and prohibition are regarded as (...) analogous to the "alethic" modalities necessity, possibility and impossibility. As Simo Knuuttila shows in his contribution to the present volume, this approach goes back to late medieval philosophy. Several 14th century philosophers observed the analogies between deontic and alethic modalities and discussed the deontic interpretations of various laws of modal logic. In contemporary deontic logic the modal approach was revived by G. H. von Wright's classic paper 'Deontic Logic'. Certain analogies between deontic and alethic modalities are obvious and uncontroversial, but the standard approach has often been criticized on the ground that it exaggerates the analogies and tends to ignore those features of normative concepts which distinguish them from other modalities.

This chapter begins with a discussion of Herbart's theory of the structures of thought. It then discusses Drobisch's formal philosophy, Hegel's dialectical logic, Trendelenburg's logical investigations, and Herbartian and Hegelian reactions to the criticism.

Recognition and Religion: A Historical and Systematic Study outlines the first intellectual history of religious recognition, stretching from the New Testament to present day. Risto Saarinen connects the history of religion with philosophical approaches, arguing that philosophers owe a considerable historical and conceptual debt to the religious processes of recognition. At the same time, religious recognition has a distinctive profile that differs from philosophy in some important respects. Saarinen undertakes a systematic elaboration of the insights provided by the tradition (...) of religious recognition. He proposes that theology and philosophy can make creative use of the long history of religious recognition. (shrink)

In this paper the author examines the ontology of Byzantine music in its self, its aesthetical ground, the philosophical and cultural principles of creation, its episteme, the epistemological field that produced its forms from the 12th till the 14th century, and why that musical ontology hasn’t change through the centuries. The paper discusses in partucular Ernst Bloch’s view that the only evolutionary expression of the Absolute spirit as far as music is concerned, is Western classical music. The author claims that (...) the Western and the Byzantine music stand for two totally distinct and diverse ontologies of the musical being, something that Bloch seems to overlook; this, according to the author, is mostly due to the different systems of representation that have been used, and especially the representational ideas of the time-space relation. The author supports the view that while Western music is spatially-modeled, Byzantine music is time-modeled. (shrink)

Peirce discusses the nature and structure of propositions in several manuscripts written in the 1890’s and during the first decade of this century. In this paper I shall outline the main features of Peirce’s theory of the proposition, especially his account of what may be called indeterminate indices in propositions.

This volume examines the medieval understanding of Aristotle's "weakness of the will". The medieval views are outlined on the basis of five major commentaries on Aristotle's _Nicomachean Ethics_ between 1250 and 1350.

Many medieval philosophers and logicians regarded modal logic as a model for epistemic, normative and optative concepts on the basis of their apparent similarities to modal concepts. These interpretations of modal logic led to critical studies of the applicability of modal principles to deontic concepts. Some philosophers presented apparent counterexamples to the deontic interpretation of the Consequence Principle, according to which the consequences of what is obligatory (or permitted) are also obligatory (permitted). These examples are variants of Lennart Åqvist's paradox (...) of the Good Samaritan. In this article it is argued that the examples involve a confusion between the compounded and the divided senses of deontic propositions, and are not genuine counterexamples to the Consequence Principle. If the concept of knowledge is analysed as epistemically satisfactory belief, the paradox of epistemic obligation can be solved in a similar way. (shrink)

Many philosophers have used the concept of belief system or some related notion as a basic tool of epistemological discussion and analysis. A belief system is a set of propositions or statements which represents a person’s doxastic state or credal state in a certain situation; it consists of the propositions which the person either explicitly or implicitly accepts in the situation. One of the many concerns of epistemologists is to attempt to formulate general “conditions of rationality” for belief systems. I (...) want to suggest in the present paper that in this endeavour philosophers usually treat belief systems as if they were artifacts or tools made for various epistemic purposes: for providing satisfactory answers to interesting questions, for helping to find answers to new questions, and for providing resources for argumentation and research. Insofar as epistemology and philosophy of science can legitimately be viewed in this way, they may be regarded as “sciences of the artificial” in Herbert Simon’s sense, and not as sciences of the “natural world” or parts of natural science, as some proponents of “naturalised epistemology” have recently suggested.

Many historians and philosophers of logic have claimed that during the modern classical era there was a long period of stagnation or even of decline in the field of logic. The aim of this paper is to convince the audience that this standard evaluation of the development of modern logic during the period from Leibniz to Frege is misdirected and needs to be corrected. Even though it is true that the now usual way of understanding logic merely as the doctrine (...) of syntax and semantics of explicit languages would not have appealed even to most 19th century logicians, it is still not the case that there is nothing worth discussing with regard to the development of logic during the modern classical period. The algebraic period culminated with Schroder's contribution and neither Herbartian formal logic nor Trendelenburg's critical epistemology aroused much interest among the 20th century mathematical logicians and analytic philosophers. Nevertheless, the development of symbolic logic can only be understood properly by relating its emergence to the immediately preceding philosophically-oriented discussion about the reform of logic.

Dust jacket, back cover: In this book, Risto Saarinen studies Martin Luther's understanding of the gift and related issues such as favours and benefits, faith and justification, virtues and merits, ethics and doctrine, law and Christ. He shows that Luther both continues and criticizes the classical discusssions regarding the differences and parallels between gifts and sales.
