Theor of free choice permission

I argue that the conjunctive distribution of permissibility over or, which is a puzzling feature of free-choice permission is just one instance of a more general class of conjunctive occurrences of the word, and that these conjunctive uses are more directly explicable by the consideration that or is a descendant of oper than by reference to the disjunctive occurrences which logicalist prejudices may tempt us to regard as semantically more fundamental. I offer an account of how the disjunctive uses of or may have come about through an intermediate discourse-adverbial use of or, drawing a parallel with but, which, etymologically, is disjunctive rather than conjunctive and whose conjunctive uses seem to represent just such a discourse-adverbial application.     

The relativity of perceptual knowledge

Since the most promising path to a solution to the problem of skepticism regarding perceptual knowledge seems to rest on a sharp distinction between perceiving and inferring, I begin by clarifying and defending that distinction. Next, I discuss the chief obstacle to success by this path, the difficulty in making the required distinction between merely logical possibilities that one is mistaken and the real (Austin) or relevant (Dretske) possibilities which would exclude knowledge. I argue that this distinction cannot be drawn in the ways Austin and Dretske suggest without begging the questions at issue. Finally, I sketch and defend a more radical way of identifying relevant possibilities that is inspired by Austin's controversial suggestion of a parallel between saying I know and saying I promise: a claim of knowledge of some particular matter is relative to a context in which questions about the matter have been raised.     

Toulmin on Ideals of Natural Order

In this paper I criticize Toulmin's concept of Ideals of Natural Order and his account of the role these Ideals play in scientific explanation as given in his book, Foresight and Understanding. I argue that Toulmin's account of Ideals of Natural Order as those theories taken to be self evident by scientists at a given time introduces an undesirable subjectivism into his account of scientific explanation. I argue also that the history of science, especially the recent history of microphysics, does not support Toulmin's contentions about the supposed self-evidence of the basic explanatory theories in science.     

Les “règles de la discussion légitime” dans la logique de Port-Royal

In the XVIIth century the conflict which opposed the jansenists to the jesuits involved the problem of the due process in theological matter. The jesuits heralded the thesis that the infallibility of the Church has to be extended from dogmatics (quaestio iuris) to the historical facts (quaestio facti). On the opposite side Arnauld maintained that such an opinion was monstruous: also in religious matters the fact has to be proved according to the principles of a due process, and not by authority. In this article the thesis pleaded by the jansenists is considered in connection with the model of argumentative procedure offered by the Port-Royal logic.The Logique ou Art de penser (1622) by Antoine Arnauld and Pierre Nicole seems to have rediscovered the classical principles of the theory of argumentation: from the burden of proof to the idea of probable truth. But really a new model of adversary-system has been introduced into the modern mind, which is very different in concept from the topical tradition. The basic metaphor of combat, implying that the truth will prevail in the fight, is compatible with the epistemological premises of the modern logic (as the separation between fact and value). Therefore the problem of the fact-finding seems to be attracted into the area of the logic of information, and not of the theory of argumentation.

     

Was Marx an ethical humanist?

Zusammenfassung Während der letzten zehn Jahre wurde viel über den Humanismus des jungen Marx gesprochen. Osteuropäische Marxisten, die bemüht sind, ihren Anti-Stalinismus durch Berufung auf die Autorität von Marx selbst zu untermauern, gebrauchen den Ausdruck Humanismus in einem ungenauen Sinn, etwa gleichbedeutend mit Anthropozentrismus. Aber wenn man sagt, daß Marx Haltung anthropozentrisch sei, so sind damit die Hauptfragen erst gestellt, nicht schon gelöst.Humanismus mag etwa soviel wie Säkularismus bedeuten — der Mensch, nicht Gott, wird als im Mittelpunkt stehend gedacht. Die anthropozentrische Haltung kann verschiedene Formen annehmen, vor allem die Formen, die man als Humanismus der Ideale und als Humanismus der Prinzipien bezeichnen könnte. Der Humanismus der Ideale ist ausdrücklich an derZukunft orientiert, der Humanismus der Prinzipien aber an derGegenwart. Nur ein Humanismus der Prinzipien, dem es darum geht, den Eigenwert existierender Individuen zu behaupten und zu verteidigen, verdient es, ethischer Humanismus genannt zu werden. Marx, sogar der jüngste Marx, war kein ethischer Humanist in diesem Sinn. Und nur ein Humanismus in diesem strengen Sinn würde einen philosophischen Standort bieten, von dem aus man den Stalinismus oder Neo-Stalinismus angreifen könnte.Marx war ein Säkularist, und er entwarf ein humanistisches Ideal für die Zukunft, aber humanistische Prinzipien für die Gegenwart lehnte er ab. Er betonte, daß nur dem nicht entfremdeten, produktiven Individuum der kommunistischen Zukunft ein eigener Wert zukomme. Bis dahin haben Individuen nur einen geschichtlich instrumentalen Wert: jene, die an der Verwirklichung der kommunistischen Gesellschaft arbeiten, sind zu respektieren; diejenigen, welche dabei Widerstand leisten oder versagen, müssen ausschließlich als Hindernisse auf dem Wege des geschichtlichen Fortschritts behandelt werden.In diesem Sinn ist der Leninismus und sogar der Stalinismus und Neo-Stalinismus in dem zukunftsorientierten Humanismus der Ideale des jungen Marx einbegriffen, oder zumindest davon nicht ausgeschlossen. Selbst der jüngste Marx machte sich den Modeirrtum des 19. Jahrhunderts zu eigen — den Irrtum des aufgeschobenen Wertes oder des zeitlich verstellten Wertes und nahm damit eine mit dem ethischen Humanismus grundsätzlich unvereinbare Position ein.

On some structural aspects of physical problems

Bachelard's concept of the problématique is used in order to classify physical problems and their interrelations. This classification is effectuated along two dimensions. Along the horizontal dimension, physical problems are divided into the kinds that the different modes of physics' development define. These modes are themselves determined by the interplay among the conceptual system, the object and the experimentation transactions specific to physics. Along the vertical dimension, physical problems are classified according to the different stages of maturation they have to undergo before the process of their solution is effectively undertaken. To determine these maturation stages, the Althusserian conception of ideology is used. The interrelations between physical problems are examined through the introduction and elaboration of the notion interdependence network.It is a pleasure to thank Marcello Pera and Kostas Gavroglou for their very helpful comments and criticisms.     

Ideologic Learning Under Conditions of Social Enslavement: The Case of the Soviet Union in the 1930s AND 1940s

A sequence of theoretical models is constructed as an extension to Leszek Nowak's theory of socialist society to explain important characteristics of the violent party purges in Soviet Stalinism. According to these models, purges are a regular and systemic feature of a socialist system during a certain phase of development (modelled as the phase of social enslavement). Contrary to traditional conceptions which interpret the purges essentially as resulting from the actions of an almost omnipotent, and partly irrational, despot, the models presented here provide an explanation which does not need to conceive Stalin as the architect of terror (Robert Conquest), i.e. as the long-term planner of the terror. However, the concepts presented here preserve the vital arguments of the traditional approach, thereby contradicting the revisionist pattern of interpretation. In particular the models seek to provide a theoretical base for an explanation of the moderation of inner-party terror from 1938. This moderation is interpreted as resulting from a modification of the then existing ideology (and corresponding habits of the party's leadership); a modification which in itself had been stimulated by the disastrous effects of the great purge in 1937/38. This modification can be theoretically conceived as a process of ideological learning. The historical fact that the post-war purges (i.e. the Leningrad affair in 1949 and the Mingrelian affair 1951/52) did not reach such an enormous extent as the purges of the late 1930s may thus be attributed to a process of ideological learning.     

The Role of Public Argument in Emerging Democracies: A Case Study of the 12 December 1993 Elections in the Russian Federation

The authors argue that in the 1993 Duma elections it was the Communist Party of the Russian Federation, led by Gennady Zyuganov, that incorporated rhetorical values and audience adaptation into its campaign strategy. Finding its discursive ground limited by history, the CPRF gradually shifted its rhetorical posture and argumentative strategies, redefining itself in the process. This evolution allowed the CPRF to employ the ideographs of democracy, will of the people, citizen, and other key terms of Western-style democracy, while retaining, albeit in transformed meaning, traditional communist ideographs such as justice and spirituality. In addition, the CPRF was able to borrow selectively from the history of the USSR between 1917 and 1989, thereby imbuing their political appeals with historical force and cultural memory.     

Quantum Mechanical Unbounded Operators and Constructive Mathematics – a Rejoinder to Bridges

As argued in Hellman (1993), the theorem of Pour-El and Richards (1983) can be seen by the classicist as limiting constructivist efforts to recover the mathematics for quantum mechanics. Although Bridges (1995) may be right that the constructivist would work with a different definition of closed operator, this does not affect my point that neither the classical unbounded operators standardly recognized in quantum mechanics nor their restrictions to constructive arguments are recognizable as objects by the constructivist. Constructive substitutes that may still be possible necessarily involve additional incompleteness in the mathematical representation of quantum phenomena. Concerning a second line of reasoning in Hellman (1993), its import is that constructivist practice is consistent with a liberal stance but not with a radical, verificationist philosophical position. Whether such a position is actually espoused by certain leading constructivists, they are invited to clarify.     

Natural deduction rules for English

A system of natural deduction rules is proposed for an idealized form of English. The rules presuppose a sharp distinction between proper names and such expressions as the c, a (an) c, some c, any c, and every c, where c represents a common noun. These latter expressions are called quantifiers, and other expressions of the form that c or that c itself, are called quantified terms. Introduction and elimination rules are presented for any, every, some, a (an), and the, and also for any which, every which, and so on, as well as rules for some other concepts. One outcome of these rules is that Every man loves some woman is implied by, but does not imply, Some woman is loved by every man, since the latter is taken to mean the same as Some woman is loved by all men. Also, Jack knows which woman came is implied by Some woman is known by Jack to have come, but not by Jack knows that some woman came.     

Beyond verisimilitude: A linguistically invariant basis for scientific progress

This paper proposes a solution to David Miller's Minnesotan-Arizonan demonstration of the language dependence of truthlikeness (Miller 1974), along with Miller's first-order demonstration of the same (Miller 1978). It is assumed, with Peter Urbach, that the implication of these demonstrations is that the very notion of truthlikeness is intrinsically language dependent and thus non-objective. As such, truthlikeness cannot supply a basis for an objective account of scientific progress. I argue that, while Miller is correct in arguing that the number of true atomic sentences of a false theory is language dependent, the number of known sentences (under certain straightforward assumptions) is conserved by translation; degree of knowledge, unlike truthlikeness, is thus a linguistically invariant notion. It is concluded that the objectivity of scientific progress must be grounded on the fact (noted in Cohen 1980) that knowledge, not mere truth, is the aim of science.For criticism and comments I am indebted to Noretta Koertge, David Miller, and an anonymous Synthese referee.     

Some notes on the nature of methodological indeterminacy

This paper is an attempt to extend the meaning of the concept of indeterminacy for the human sciences. The authors do this by coining the term methodological indeterminacy and arguing that indeterminacy is better understood when linked to specific methodological techniques. Paradoxically, while specific research techniques demonstrate that the issue of indeterminacy is complex, yielding the possibility of types and degrees, it does not eliminate the problem of translation first raised by Quine. However, the authors go on to argue that, from a research perspective, indeterminacy can and must be approached in such a way that it is possible to reduce cases of it, even though never completely eliminating it in the human sciences.     

A notorious affair called exportation

In Quantifiers and Propositional Attitudes, Quine held (a) that the rule of exportation is always admissible, and (b) that there is a significant distinction between a believes-true (Ex)Fx and (Ex) a believes-true F of x. An argument of Hintikka's, also urged by Sleigh, persuaded him that these two intuitions are incompatible; and he consequently repudiated the rule of exportation. Hintikka and Kaplan propose to restrict exportation and quantifying in to favoured contexts — Hintikka to contexts where the believer knows who or what the person or thing in question is; Kaplan to contexts where the believer possesses a vivid name of the person or thing in question. The bulk of this paper is taken up with criticisms of these proposals. Its ultimate purpose, however, is to motivate an alternative approach, which imposes no restrictions on exportation or quantifying in, but repudiates Quine's other intuition: this is the approach taken in my A Logical Form for the Propositional Attitudes.This paper is based on my doctoral dissertation (Rockefeller University, 1977). I wish to thank Susan Haack for her help in turning a draft into the present version.     

Technical flaws in the coherence theory

Conclusion We have argued that Lehrer's definitions of coherence and justification have serious technical defects. As a result, the definition of justification is both too weak and too strong. We have suggested solutions for some of the problems, but others seem irremediable. We would also argue more generally that if coherence is anything like what Lehrer's theory says it is, then coherence is neither necessary nor sufficient for justification. While our current objections are directed at the letter of Lehrer's theory, other criticisms can be aimed at its very spirit. We would argue that coherence is unnecessary for justification because of the existence of basic beliefs, those about self-presenting states (I have a tingling sensation in my leg) or self-evident truths (All men are men). Such beliefs may be justified even though there are no other propositions in the subject's acceptance system that makes them more probable than competitors. Coherence is, moreover, insufficient for justification, because it ignores the inferential structure of the subject's acceptance system, and requires no justification of any kind for the subject's acceptance system itself. But we must develop these more fundamental objections on another occasion.     

Stuffed Cabbage in the Old New School Cafeteria

The purpose of this lecture is to celebrate the memory of Aron Gurwitsch by examining and enlarging the domain of phenomenological clarification of some elements of what Gurwitsch called the logic of reality. Chief among those elements are the nature of the taken-for-grantedness of our existential belief, the difference between presentive and non-presentive indices of reality and the ground for the self-illumination of the world of working.     

The array size function in simple visual search tasks: A comparison between “go-no go” and “yes-no” tasks under conditions of high and low target-noise similarity

Summary In research on visual search within a single eye-fixation a number of different tasks are used and referred to interchangeably. Research with other types of tasks suggests that there are possibly important differences between these tasks. In the present study, two types of search tasks were compared under conditions as equal as possible: the go-no go task and the yes-no task. Conditions of low and high target-noise similarity were used. The results obtained showed: a) a steeper slope of the array size function in yes-no tasks than in go-no go tasks on the first day of practice but not on the second: b) a higher intercept value of the same function for yes-no tasks than for go-no go tasks; and c) a greater proportion of errors with yes-no tasks than with comparable go-no go tasks. A tentative model, describing the main features of the results obtained, is briefly sketched.     

“The story says that” operator in story semantics

In [2] a semantics for implication is offered that makes use of stories — sets of sentences assembled under various constraints. Sentences are evaluated at an actual world and in each member of a set of stories. A sentence B is true in a story s just when B s. A implies B iff for all stories and the actual world, whenever A is true, B is true. In this article the first-order language of [2] is extended by the addition of the operator the story ... says that ..., as in The story Flashman among the Redskins says that Flashman met Sitting Bull. The resulting language is shown to be sound and complete.     

Three views of demonstrative reference

Three views of demonstrative reference are examined: contextual, intentional, and quasi-intentional. According to the first, such reference is determined entirely by certain publicly accessible features of the context. According to the second, speaker intentions are criterial in demonstrative reference. And according to the third, both contextual features and intentions come into play in the determination of demonstrative reference. The first two views (both of which enjoy current popularity) are rejected as implausible; the third (originally proposed by Kaplan in Dthat) is argued to be highly plausible.     

The relevance of Habermas' communicative turn

This paper points out the way in which educational and communicative action (Habermas) are to be related. It is shown that earlier attempts to put Habermas ideas to use have led to a dead end because they do not realize clearly that the new basic notion introduced by Habermas, namely communicative action, is the expression of a communicative turn. It is argued that Habermas' concept expresses a radical new attempt to grasp the intersubjective character of social action. Next implications of this communicative turn for the concept of education as a social praxis are indicated. Education can be conceived of as a praxis responding to the vulnerability of a communicative self.     

Valuational semantics of rule derivability

If a certain semantic relation (which we call local consequence) is allowed to guide expectations about which rules are derivable from other rules, these expectations will not always be fulfilled, as we illustrate. An alternative semantic criterion (based on a relation we call global consequence), suggested by work of J.W. Garson, turns out to provide a much better — indeed a perfectly accurate — guide to derivability.
