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 relationship between perceived surface-lightness and perceived illumination

Summary An attempt was made to specify the relationship between perceived surface lightness and perceived illumination under the stimulus conditions where different combinations of albedo and illuminance gave 10 approximately equal-luminance levels of a test field (TF) on three different (black-, gray- and white-appearing) backgrounds. Two types of category judgments for TF-lightness and overall illumination were made on the total of 94 TFs by 5 Ss. The results indicated that under the condition where achromatic surface colors appear, the perceptual scission which produces two different perceptual dimensions (lightness and perceived illumination) from one sort of stimulation (luminance) was clearly observed. The relation between the two judgments was consistent with the lightness-illumination invariance hypothesis: As lightness judgments (A) changed from darker to lighter, illumination judgments (I) shifted form brighter to dimmer, the sum of A and I being kept nearly invariant for a given luminance of the TF; the psychological relationship between lightness and illumination, A+I, changed as a linear function of the photometric combination of albedo and illuminance, log A+log I. It was also found that the albedo of the background was an important factor determining the extent of perceptual scission between lightness and illumination.     

The artist as transgressor in Mandel'štam's poetry

In Mandel'tam's writing, artistic creativity is described as based on the indispensable yet contradictory modes of compliance and deviation. The artist, by his artistic nature, must be an obedient disciple to the tradition that inspires him, and, at the same time, a violator who renders what inspires him in an individual form. Thus, art implies iterability through novelty. In the totalitarian state, this double nature of art acquires a sinister context and brings the artist to an unavoidable conflict with the state. He has a choice between a servile compliance with the state's command and artistic independence. If the artist complies, he loses his ingenuity; if, on the other hand, he has the courage to break away from the established order, his fate is martyrdom. The criteria of truth and falsehood, the issue of loyalty, of compromise and collaboration or resistance become most relevant. Such words as outcast or non-contemporary acquire the meaning of non-collaborationist or enemy of the people. In the totalitarian state a genuine artist is viewed as a law-breaker, and his art leads him to crime. The notions of compliance and deviation cease being merely aesthetic terms and assume in Mandel'tam's poetry complex, subtle and tragic overtones.I would like to express my gratitude to John Barnstead, Thomas Blakeley, James Doull, Elena Glazov-Corrigan, Gregory Glazov, Leonard Kazdan, Peter Kussmaul, Malcolm Ross, Detlev Steffen, and Ieva Vitins for their valuable criticism, suggestions, and revisions of my English.     

Third Men: The Logic of the Sophisms at Arist. SE 22, 178b36–170a10

This article aims at elucidating the logic of Arist. SE 22, 178b36–179a10 and, in particular, of the sophism labelled "Third Man" discussed in it. I suggest that neither the sophistic Walking Man argument, proposed by ancient commentators, nor the Aristotelian Third Man of the , suggested by modern interpreters, can be identified with the fallacious argument Aristotle presents and solves in the passage. I propose an alternative reconstruction of the Third Man sophism and argue that an explanation of the lines regarding the identity of Coriscus and Coriscus the musician (178b39–179a3) is indispensable for its correct understanding, since they hint at another sophism in some important aspects analogous. Finally, I show that two contradictions concerning spotted by scholars in the passage are only apparent and can be dissolved once the assumption that the anti-Platonic Third Man argument is at stake here is discarded, and once the passage is read in the light of its agonistic context.     

A modification of kendall's tau for measuring association in contingency tables

A coefficient of association is described for a contingency table containing data classified into two sets of ordered categories. Within each of the two sets the number of categories or the number of cases in each category need not be the same.=+1 for perfect positive association and has an expectation of 0 for chance association. In many cases also has –1 as a lower limit. The limitations of Kendall's _a and _b and Stuart's _c are discussed, as is the identity of these coefficients to' under certain conditions. Computational procedure for is given.     

Iconic memory — an artifact of perceptual reconstruction processes?

Summary Two experiments, using a partial vs. whole report procedure to isolate iconic from short-term memory loss, are reported. In the first experiment 10 Ss had to judge the difference between two line lengths in a display of three pairs of lines (in rows). Results showed no significant variation in d' with cue delay in spite of a medium overall performance, and in contrast to preliminary partial/whole report experiments. To counter the possibility that the short-term memory load was too small in this experiment, a second experiment was performed with displays containing nine instead of three pairs, i.e., three pairs per row. Equivalence of performance for all conditions was about the same as before. This was true for both hit- and false-alarm rates. The results are interpreted as evidence against the view of iconic memory as a high capacity store containing a lot of information. An alternative reconstructive theory is put forward to explain both conventional iconic loss and our results. According to this account, partial report measures processed material rather than reflecting an iconic store of uninterpreted sensory events. Some consequences of this model are discussed in the context of some weak effects in our data; and suggestions are put forward for further investigation of visual processing.The experiments to be reported here were made possible by grant Schu 421/1–2 of the Deutsche Forschungsgemeinschaft. The main results of Experiment II have already been reported at the European Conference on Visual Perception at Nordwijkerhout, October 1979. I am indebted to Mrs. R. Ledebur, cand. phil, and Dipl.-Psych. G. Gros who collected the data. I also wish to thank Dr. A. Reeves (Dortmund) for helpful comments on an earlier version of this paper. Dr. P. Wolff (Osnabrück) and two anonymous reviewers contributed valuable suggestions concerning the final draft     

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 reduction rule for Peirce formula

A reduction rule is introduced as a transformation of proof figures in implicational classical logic. Proof figures are represented as typed terms in a -calculus with a new constant P ⁽⁽⁾⁾. It is shown that all terms with the same type are equivalent with respect to -reduction augmented by this P-reduction rule. Hence all the proofs of the same implicational formula are equivalent. It is also shown that strong normalization fails for P-reduction. Weak normalization is shown for P-reduction with another reduction rule which simplifies of (( ) ) into an atomic type.This work was partially supported by a Grant-in-Aid for General Scientific Research No. 05680276 of the Ministry of Education, Science and Culture, Japan and by Japan Society for the Promotion of Science.

Vulnerability schemas of individuals in couples relationships: a cognitive perspective

The professional literature has recently given attention to addressing individual schemas in couples relationships, with particular emphasis on the fact that individual vulnerability has a significant impact on couples relationships. This article addresses how this vulnerability can be restructured during the course of couples therapy. Case vignettes are used to illustrate how the model can be applied. Some of the implications of this model are considered in the discussion section.Authors note: Portions of this article were published in Norwegian by the first author and appear in Nordby, T.T. (2002): Kognitiv parterapi. En tilnærming som ivaretar betydningen av den individuelle sårbarheten i samspillet. Reprinted by permission of Fokus på familien 30, 46–60.     

Superintuitionistic Companions of Classical Modal Logics

This paper investigates partitions of lattices of modal logics based on superintuitionistic logics which are defined by forming, for each superintuitionistic logic L and classical modal logic , the set L[] of L-companions of . Here L[] consists of those modal logics whose non-modal fragments coincide with L and which axiomatize if the law of excluded middle p V p is added. Questions addressed are, for instance, whether there exist logics with the disjunction property in L[], whether L[] contains a smallest element, and whether L[] contains lower covers of . Positive solutions as concerns the last question show that there are (uncountably many) superclean modal logics based on intuitionistic logic in the sense of Vakarelov [28]. Thus a number of problems stated in [28] are solved. As a technical tool the paper develops the splitting technique for lattices of modal logics based on superintuitionistic logics and ap plies duality theory from [34].     

The ω-rule

We prove that all proofs in -logic (a first order logic with -rule added) in which -rule is used finitely many times can be turned into proofs in which the -rule is used at most one time. Next, we prove that the word finitely above cannot be changed by the word infinitely.     

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.     

Libertarianism vs. Marxism: Reflections on G. A. Cohen‘s Self-Ownership, Freedom and Equality

Self-Ownership, Freedom and Equality is G.A. Cohens attempt to rescue something of the socialist outlook on society from the challenge of libertarianism, which Cohen identifies with the work of Robert Nozick in his famous book, Anarchy, State, and Utopia. Sympathizing with the leading idea that a person must belong to himself, and thus be unavailable for forced redistribution of his efforts, Cohen is at pains to reconcile the two. This cannot be done – they are flatly contrary. Moreover, equality is a nonsense principle, calling for such things as equal distribution of natural resources. But resources, as goods, are not natural: all require work to utilize. The only thing exchanged on markets is services, and estimates of value received are relevantly made only by those party to the exchanges in question. Imposition from above on voluntary exchange can only be socially counterproductive.

Applying modal logic

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.

Socialism in One Country: A Reassessment

Until 1917 Lenin and Trotsky believed that an isolated revolutionary Russia would have no chance of survival. However, from 1917 to 1923 Lenin's standpoint on this matter underwent a complete reversal. First he came to the conclusion that socialism could be built in an isolated Russia, although it would remain incomplete in the absence of the world revolution. By 1923 he was abandoning that latter qualification too. The standpoint of Stalin and Bukharin in the debate on socialism in one country of 1925–26 was more orthodox-Leninist than the position taken by Trotsky, who had at first also embraced the notion of incomplete socialism, but subsequently returned to the old concept, abandoned by Lenin, that the restoration of capitalism was inevitable in the absence of the world revolution.     

Mathematical modeling of the effects of ‘capability’ and ‘intent’ on the stability of a competitive international system

In international relations theory, there is a long history of Richardson-like modeling of the evolution of military capability. Usually, such models are deterministic and predictive and do not allow for the representation of the transition from competitive peace to shooting war. More recently, models have been developed which attempt to represent the evolution of relationship between nations. The relationship between nations, varying from friendship to hostility, is taken to be synonymous with the intent of nations towards each other, varying from good will to malice. Generally, these relationship models do not include capability though common sense would indicate that capability and mutual intent should profoundly influence each other. A model is presented here which combines these two fundamental attributes of international relations and attempts to represent the outbreak of war in the world system by the onset of deterministic chaos in the extended model.On leave 1994–95 at U.S. Arms Control and Disarmament Agency, Washington, D.C. 20451, U.S.A.     

Utility theory with inexact preferences and degrees of preference

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.     

Early German approaches to experimental reading research: The contributions of Wilhelm Wundt and Ernst Meumann

Summary Wundt looked at the reading process from a predominantly theoretical perspective. He opposed the total shape theory formulated by Erdmann and Dodge and insisted on the occurrence of attention shifts during word recognition. As an alternative to the total shape theory, he formulated a two-stage theory of word recognition. An initial, apperceptive phase of reading is concerned with the active analysis of visually salient local details, and a second, assimilative phase fills in the unanalyzed parts of words on the basis of a passive evocation of earlier experiences with graphemic input. Meumann looked at the reading process from the point of view of an educational psychologist. His review of experimental reading research presents most of the basic issues which are still controversial today. In his recommendations for the teaching of reading, he emphasized the importance of analyzing words into their constituent sounds and of articulatory awareness as a precondition for the firm establishment of connections between graphemes and speech sounds. The review discusses some of the reasons why the experimentally based approach to the psychology of reading failed to evoke the interest of German educators after World War I.
