Different aspects of people's interactions with money are best conceptualized using the drug and tool theories. The key question is when these models of money are most likely to guide behavior. We suggest that the Drug Theory characterizes motivationally active uses of money and that the Tool Theory characterizes behavior in motivationally cool situations. (Published Online April 5 2006).
Tests of economic theory often focus on choice outcomes and find significant individual differences in these outcomes. This variability may mask universal psychological processes that lead to different choices because of differences across cultures in the information people have available when making decisions. On this view, decision making research within and across cultures must focus on the processes underlying choice.
This paper is based on Lectures 1, 2 and 4 in the series of ten lectures titled “Algebraic Structures for Logic” that Professor Blok and I presented at the Twenty Third Holiday Mathematics Symposium held at New Mexico State University in Las Cruces, New Mexico, January 8-12, 1999. These three lectures presented a new approach to the algebraization of deductive systems, and after the symposium we made plans to publish a joint paper, to be written by Blok, further (...) developing these ideas. That project was still incomplete when Blok died. In fact, there is no indication that he had prepared a draft of the paper, and we do not know what new material he intended to include. I am therefore not in a position to complete the project as he had envisioned it. So, I have settled for the more limited objective of presenting the material from the three lectures, leaving to others the task of adapting the techniques used there to more general situations.

In the thirties, Martin Heidegger was heavily involved with the work of Ernst Jünger (1895-1998). He says that he is indebted to Jünger for the ‘enduring stimulus’ provided by his descriptions. The question is: what exactly could this enduring stimulus be? Several interpreters have examined this question, but the recent publication of lectures and annotations of the thirties allow us to follow Heidegger’s confrontation with Jünger more precisely. -/- According to Heidegger, the main theme of his philosophical thinking in the (...) thirties was the overcoming of the metaphysics of the will to power. But whereas he seems to be quite revolutionary in heralding ‘another beginning’ of philosophy in the beginning of the thirties, he later on realized that his own revolutionary vocabulary was itself influenced by the will to power. In his later work, one of the main issues is the releasement from the wilful way of philosophical thinking. My hypothesis is that Jünger has this importance for Heidegger in the thirties, because the confrontation with Jünger’s way of thinking showed him that the other beginning of philosophy presupposes the irrevocable releasement of willing and a gelassen or non-willing way of philosophical thinking. -/- In this article, we test this hypothesis in relation to the recently published lectures, annotations and unpublished notes from the thirties. After a brief explanation of Jünger’s diagnosis of modernity (§1), we consider Heidegger’s reception of the work of Jünger in the thirties (§2). He not only sees that Jünger belongs to Nietzsche’s metaphysics of the will to power, but also shows the modern-metaphysical character of Jünger’s way of thinking. In section three, we focus on Heidegger’s confrontation with Jünger in relation to the consummation of modernity. According to Heidegger, Jünger is not only the end of modern metaphysics, but also the perishing (Verendung) of this end, the oblivion of this end in the will to power of representation. In section four, we focus on the real controversy between Jünger and Heidegger: the releasement of willing and the necessity of a radical other beginning of philosophical thinking. -/- . (shrink)
The notion of an algebraic semantics of a deductive system was proposed in [3], and a preliminary study was begun. The focus of [3] was the definition and investigation of algebraizable deductive systems, i.e., the deductive systems that possess an equivalent algebraic semantics. The present paper explores the more general property of possessing an algebraic semantics. While a deductive system can have at most one equivalent algebraic semantics, it may have numerous different algebraic semantics. All of these give rise to (...) an algebraic completeness theorem for the deductive system, but their algebraic properties, unlike those of equivalent algebraic semantics, need not reflect the metalogical properties of the deductive system. Many deductive systems that don't have an equivalent algebraic semantics do possess an algebraic semantics; examples of these phenomena are provided. It is shown that all extensions of a deductive system that possesses an algebraic semantics themselves possess an algebraic semantics. Necessary conditions for the existence of an algebraic semantics are given, and an example of a protoalgebraic deductive system that does not have an algebraic semantics is provided. The mono-unary deductive systems possessing an algebraic semantics are characterized. Finally, weak conditions on a deductive system are formulated that guarantee the existence of an algebraic semantics. These conditions are used to show that various classes of non-algebraizable deductive systems of modal logic, relevance logic and linear logic do possess an algebraic semantics. (shrink)
There exist important deductive systems, such as the non-normal modal logics, that are not proper subjects of classical algebraic logic in the sense that their metatheory cannot be reduced to the equational metatheory of any particular class of algebras. Nevertheless, most of these systems are amenable to the methods of universal algebra when applied to the matrix models of the system. In the present paper we consider a wide class of deductive systems of this kind called protoalgebraic logics. These include (...) almost all (non-pathological) systems of prepositional logic that have occurred in the literature. The relationship between the metatheory of a protoalgebraic logic and its matrix models is studied. The following results are obtained for any finite matrix model U of a filter-distributive protoalgebraic logic : (I) The extension U of is finitely axiomatized (provided has only finitely many inference rules); (II) U has only finitely many extensions.

We agree that supernatural beliefs are pervasive. However, we propose a more general account rooted in how people trace ordinary objects over time. Tracking identity involves attending to the causal history of an object, a process that may implicate hidden mechanisms. We discuss experiments in which participants exhibit the same “supernatural” beliefs when reasoning about the fates of cups and automobiles as those exhibited by Bering's participants when reasoning about spirits.
Let S denote the variety of Sugihara algebras. We prove that the lattice (K) of subquasivarieties of a given quasivariety K S is finite if and only if K is generated by a finite set of finite algebras. This settles a conjecture by Tokarz [6]. We also show that the lattice (S) is not modular.
This contribution discusses the philosophical meaning of the Martin Heidegger’s Rectoral address. First of all, Heidegger’s philosophical basic experience is sketched as the background of his Rectoral address; the being-historical concept of “Anfang”. Then, the philosophical question of the Rectoral address is discussed. It is shown, that Die Selbstbehauptung der deutschen Universität is asking for the identity of human being there (Dasein) in connection with the question about dem Eigenen (the Germans) and dem Fremden (the Greeks). This opposition structuralizes the (...) confrontation with the beginning of philosophical thinking in the Rectoral address. When read against the philosophical background sustaining the Rectoral address, words appearing therein such as “Kampf”, “Macht”, “Volk” and “Marsch” have nothing in common with the same words as used by the Nazis. It is shown that the Rectoral address is an extremely ambiguous text, because it claims a transformation of human being there (Dasein). Although Heidegger’s view on National Socialism is distinguished from Nazis ideology, it is clear that he made a mistake about Hitler. This article makes clear how Heidegger later changed his mind and vocabulary, and in what way this kind of mistakes and changes of mind are inherent to philosophical empiricism. (shrink)
We study modal logics in the setting of varieties of modal algebras. Any variety of modal algebras generated by a finite algebra — such, a variety is called tabular — has only finitely many subvarieties, i.e. is of finite height. The converse does not hold in general. It is shown that the converse does hold in the lattice of varieties of K4-algebras. Hence the lower part of this lattice consists of tabular varieties only. We proceed to show that there is (...) a continuum of pretabular varieties of K4-algebras — those are the non-tabular varieties all of whose proper subvarieties are tabular — in contrast with Maksimova's result that there are only five pretabular varieties of S4-algebras.

Modal logics are studied in their algebraic disguise of varieties of so-called modal algebras. This enables us to apply strong results of a universal algebraic nature, notably those obtained by B. Jonsson. It is shown that the degree of incompleteness with respect to Kripke semantics of any modal logic containing the axiom □ p → p or containing an axiom of the form $\square^mp \leftrightarrow\square^{m + 1}p$ for some natural number m is 2 ℵ 0 . Furthermore, we show that (...) there exists an immediate predecessor of classical logic (axiomatized by $p \leftrightarrow \square p$ ) which is not characterized by any finite algebra. The existence of modal logics having 2 ℵ 0 immediate predecessors is established. In contrast with these results we prove that the lattice of extensions of S4 behaves much better: a logic extending S4 is characterized by a finite algebra iff it has finitely many extensions and any such logic has only finitely many immediate predecessors, all of which are characterized by a finite algebra.

Pothos suggests dispensing with the distinction between rules and similarity, without defining what is meant by either term. We agree that there are problems with the distinction between rules and similarity, but believe these will be solved only by exploring the representations and processes underlying cases purported to involve rules and similarity.
The logic RM and its basic fragments (always with implication) are considered here as entire consequence relations, rather than as sets of theorems. A new observation made here is that the disjunction of RM is definable in terms of its other positive propositional connectives, unlike that of R. The basic fragments of RM therefore fall naturally into two classes, according to whether disjunction is or is not definable. In the equivalent quasivariety semantics of these fragments, which consist of subreducts of (...) Sugihara algebras, this corresponds to a distinction between strong and weak congruence properties. The distinction is explored here. A result of Avron is used to provide a local deduction-detachment theorem for the fragments without disjunction. Together with results of Sobociski, Parks and Meyer (which concern theorems only), this leads to axiomatizations of these entire fragments — not merely their theorems. These axiomatizations then form the basis of a proof that all of the basic fragments of RM with implication are finitely axiomatized consequence relations. (shrink)
The present paper is a study in abstract algebraic logic. We investigate the correspondence between the metalogical Beth property and the algebraic property of surjectivity of epimorphisms. It will be shown that this correspondence holds for the large class of equivalential logics. We apply our characterization theorem to relevance logics and many-valued logics.
Hoop residuation algebras are the {, 1}-subreducts of hoops; they include Hilbert algebras and the {, 1}-reducts of MV-algebras (also known as Wajsberg algebras). The paper investigates the structure and cardinality of finitely generated free algebras in varieties of k-potent hoop residuation algebras. The assumption of k-potency guarantees local finiteness of the varieties considered. It is shown that the free algebra on n generators in any of these varieties can be represented as a union of n subalgebras, each of which (...) is a copy of the {, 1}-reduct of the same finite MV-algebra, i.e., of the same finite product of linearly ordered (simple) algebras. The cardinality of the product can be determined in principle, and an inclusion-exclusion type argument yields the cardinality of the free algebra. The methods are illustrated by applying them to various cases, both known (varieties generated by a finite linearly ordered Hilbert algebra) and new (residuation reducts of MV-algebras and of hoops).

The veiled recession frame has served several times in the literature to provide examples of modal logics failing to have certain desirable properties. Makinson [4] was the first to use it in his presentation of a modal logic without the finite model property. Thomason [5] constructed a (rather complicated) logic whose Kripke frames have an accessibility relation which is reflexive and transitive, but which is satisfied by the (non-transitive) veiled recession frame, and hence incomplete. In Van Benthem [2] the frame (...) was an essential tool to find simple examples of incomplete logics, axiomatized by a formula in two proposition letters of degree 2, or by a formula in one proposition letter of degree 4 (the degree of a modal formula is the maximal number of nested occurrences of the necessity operator in ). In [3] we showed that the modal logic determined by the veiled recession frame is incomplete, and besides that, is an immediate predecessor of classical logic (or, more precisely, the modal logic axiomatized by the formula pp), and hence is a logic, maximal among the incomplete ones. Considering the importance of the modal logic determined by the veiled recession frame, it seems worthwhile to ask for an axiomatization, and in particular, to answer the question if it is finitely axiomatizable. In the present paper we find a finite axiomatization of the logic, and in fact, a rather simple one consisting of formulas in at most two proposition letters and of degree at most three. (shrink)
This contribution discusses the philosophical meaning of Martin Heidegger’s Rectoral address.

The question addressed in this article is to what extent a destructed concept of religion can be said to characterize the philosophical method of Martin Heidegger. In order to approach this question, we first characterize his method as “Vollzug der Fraglichkeit”: philosophy in its deepest sense does not mean to give answers to questions but to ask questions. According to Heidegger, the execution of questioning consists in the “transforming repetition” of the leading question (Leitfrage) of philosophy in order to ask (...) the basic question of philosophy (Grundfrage). In the second part of the article, we reflect on the “religious” character of Heidegger’s method of questioning. The reflection makes use of different etymological derivations of the word ‘Religion’: relegere (to observe carefully), re-eligere (to choose again), religare (to bind back), relinquere (to leave behind). In the third part of the article, we discuss what Heidegger’s “religious” method of philosophy means for present questions concerning religion. To that end, we finish with a confrontation between Heidegger and Derrida with respect to the “religious” method of philosophy. (shrink)
In the work of the Russian symbolist Andrej Belyj (1880-1934) the question concerning the essence of personality [ličnost'] plays an important role throughout his life and is developed in both his literary and philosophical-theoretical writings. Although Belyj wrote no text specifically devoted to this notion, it is nonetheless possible to reconstruct genetically a more or less cohesive theory of personality. In the case of Aleksandr Blok (1880-1921), who left behind relatively few works of a theoretical nature, the situation is (...) different. In these works, moreover, the problems involved in the notion of personality are hardly touched upon and are not philosophically deepened. Nevertheless, a few disparate elements of a notion of personality can be pointed out for Blok. /// Im Schaffen des russischen Symbolisten Andrej Belyj (1880-1934) nimmt die Frage nach dem Wesen von Persönlichkeit [ličnost'] zeit seines Lebens einen wichtigen Raum ein und ist sowohl in seinen literarischen wie philosophisch-theoretischen Schriften entwickelt. Wenngleich Belyj keinen Text verfasst hat, der sich diesem Begriff eigens widmet, können dennoch aus seinem Werk Grundzüge einer Theorie der Persönlichkeit genetisch rekonstruiert werden. Anders sieht dies im Fall von Aleksandr Blok (1880-1921) aus, der verhältnismäßig wenige Arbeiten mit theoretischem Charakter hinterlassen hat. Auch wird in ihnen die Problematik des Persönlichkeitsbegriffs kaum berührt und nicht philosophisch vertieft. Dennoch können vereinzelte Elemente eines Persönlichkeitsbegriffs für Blok aufgezeigt werden. (shrink)
It is sometimes suggested that Collingwood's philosophy of history is decidedly anti-naturalist and argues for a complete separation between history and the natural sciences. The purpose of this paper is to examine this suggestion and to argue that Collingwood's conception of the relationship between history and natural sciences is much more subtle and nuanced than such a view would allow for. In fact, there is little in Collingwood to offend contemporary naturalistic sensibilities reasonably construed. The impression that Collingwood's views are (...) incompatible with naturalism stems, in part, from an overly Kantian interpretation of the idea of rationality, as applied to historical agents, in terms of transcendentally fixed norms. This difficulty, however, does not arise if we opt for a more Hegelian interpretation of rationality in terms of continuity in thought, which Collingwood himself seemed to favor. Examining Collingwood's pronouncements on these topics leads one to the conclusion that, while objecting to the excesses of early naturalism, Collingwood saw no insurmountable obstacles to the reconciliation of science and history and their potential collaboration in some areas.

This article offers a review of Richard Rorty’s attempts to come to terms with the role of religion in our public and intellectual life by tracing the key developments in his position, partially in response to the ubiquitous criticisms of his distinction between private and public projects. Since Rorty rejects the possibility of dismissing religion on purely epistemic grounds, he is determined to treat it, instead, as a matter of politics. My suggestion is that, in this respect, Rorty’s position is (...) best construed as that of a humanist rather than a post-modernist. Ultimately, it appears that, in his view, the positive element of religion—i.e. the idea of religion as a social gospel—has been absorbed and transformed into a utopian striving which humanists associate with the ideal of democracy. Hence, in this regard, religion can be considered obsolete. Yet, without explicitly invoking the usual epistemic grounds, Rorty’s arguments for excluding religion from the public sphere remain rather thin, and an interest in reforming rather than excluding religion would have been more consistent with his general outlook.

This paper offers a critique of Derrida's deconstruction of the promise on the grounds that it does not adequately account for the ethical constitution of the promise in the pragmatic context of face-to-face dialogue. Instead, Derrida focuses on the way in which the promise opens the horizon of interpretation or readability for an indefinite community of readers. Derrida's view is explicated at length, drawing on Limited Inc, Le monolinguisme de l'autre: ou, la prosthèse d'origine, and 'Avances', the Preface to (...) class='Hi'>Serge Margel's Le tombeau du dieu artisan. Paul Ricoeur's interpretation of the promise as an attestation of my availability to the other person is presented as a more justifiable grounding of ethics.

In this first paper dealing with Heraclitus' doctrine as such (as opposed to the texts both of our sources on him and of the surviving fragments of his book), the author examines and discusses two recent controversial articles with the content of which he sympathizes - one by Gábor Betegh (2007) on the cosmological (physical) status of Heraclitus' psychê, and the other by Aryeh Finkelberg (1998) on Heraclitus' cosmogony and the reality of a Heraclitean world conflagration. This (...) examination is aimed, first, at fostering "marginal" opinions which the author believes to be fundamentally correct - and the rejection of which since times immemorial (by Schleiermacher and others) he considers to have greatly harmed and hampered our understanding of the Ephesian philosopher ; second, at introducing some personal corrections and additions to these opinions ; and third, at illustrating the advantages of a deliberately un prejudiced approach towards our sources, an approach based on the presumption of innocence, knowledgeability and intelligence for all our informers and on the rejection of any rejection [this is not a dittography!] of any source on ground of mere suspicion.Among the proposed novelties (or olden oblivitions) the following particularly deserve to be underscored: (1) the defense of the authenticity of "fr. B 76" DK qua three different fragments and (2) the reconstruction of Heraclitus' system of four physical exhalations - both of which are connected with the notion of a world soul; and (3) the interpretation of Plat. Soph. 242 C - 243 A [T 132] as confirming (and not as contradicting) Arist. De cael. 279b12 [T 170] and (4) the cosmogonical interpretation of F 31 - both of which presuppose the reality of a Heraclitean ecpyrosis.Yet, since the author's dogmatism does not extend beyond the requirement of having re course to (methodo)logically sound procedures, he is ready to give up any conclusion of which it can be proven that it is irreconcilably contradicted by a sounder one and supported by none.

While philosophers have, for centuries, pondered upon the relation between mind and brain, neuroscientists have only recently been able to explore the connection analytically — to peer inside the black box. This ability stems from recent advances in technology and emerging neuroimaging modalities. It is now possible not only to produce remarkably detailed images of the brain’s structure (i.e. anatomical imaging) but also to capture images of the physiology associated with mental processes (i.e. functional imaging). We are able to see (...) how specific regions of the brain ‘light up’ when activities such as reading this book are performed, and how our neurons and their elaborate cast of supporting cells organize and coordinate their tasks. As demonstrated in the other chapters of this book, the mapping of the human mind (mostly by measuring regional changes in blood flow, initially by positron emission tomography (PET) and recently by functional magnetic resonance imaging or (fMRI)) has provided insight into the functional neuroanatomy of neuropsychiatric diseases. Amazingly, the idea that regional cerebral blood flow (rCBF) is related intimately to brain function goes back more than a century. As is often the case in science, this idea was initially the result of unexpected observations. The Italian physiologist Angelo Mosso first expressed the idea while studying pulsations of the living human brain that keep pace with the heartbeat (Mosso, 1881). These brain pulsations can be observed on the surface of the fontanelles in newborn children. Mosso believed that they reflected blood flow to the brain. He observed similar pulsations in an adult with a post-traumatic skull defect over the frontal lobes. While studying this subject, a peasant named Bertino, Mosso observed a sudden increase in the magnitude of the ‘brain’s heart-beats’ when the church bells signalled 12 o’clock, the time for a required prayer. The changes in brain pulsations occurred independently of any change in pulsations in the forearm.. (shrink)

Research Ethics Boards (REBs) provide oversight for Canadians that research projects will comply with standards of ethics if the studies are carried out as described in the documents that have been approved. While REBs have traditionally been affiliated with institutions such as universities and hospitals, a number of factors - including the increased volume of research being conducted outside academic centres - have resulted in the establishment of some private or independent REBs. This, in turn, has raised concerns about the (...) credibility of REBs in the private sector and their capacity to handle issues around conflict of interest. This Breakout Session was an opportunity to hear the perspectives of people associated with institutional and private REBs and examine perceived problems with boards in the private sector, scrutinize theoretical and structural differences between types of REBs, and look at whether or not there is room for both institutional and private boards in the Canadian research review landscape.

This paper investigates (modal) extensions of Heyting–Brouwer logic, i.e., the logic which results when the dual of implication (alias coimplication) is added to the language of intuitionistic logic. We first develop matrix as well as Kripke style semantics for those logics. Then, by extending the Gödel-embedding of intuitionistic logic into S4 , it is shown that all (modal) extensions of Heyting–Brouwer logic can be embedded into tense logics (with additional modal operators). An extension of the Blok–Esakia-Theorem is proved for (...) this embedding. (shrink)
Soltis' paper contains little data on the underlying neural substrate of the discussed signal function of early infant crying – probably because there is amazingly little known about it.

An extensions by new axioms and rules of an algebraizable logic in the sense of Blok and Pigozzi is not necessarily algebraizable if it involves new connective symbols, or it may be algebraizable in an essentially different way than the original logic. However, extension whose axioms and rules define implicitly the new connectives are algebraizable, via the same equivalence formulas and defining equations of the original logic, by enriched algebras of its equivalente quasivariety semantics. For certain strongly algebraizable logics, (...) all connectives defined implicitly by axiomatic extensions of the logic are explicitly definable. (shrink)
Although much attention has been given to Jacques Lacan in his rereading of Freud and to French women analysts in their deconstruction of traditional psychoanalysis, little has been available in the US on contemporary male French analysts and their treatment of women.

In this paper we study the relations between the fragment L of classical logic having just conjunction and disjunction and the variety D of distributive lattices, within the context of Algebraic Logic. We prove that these relations cannot be fully expressed either with the tools of Blok and Pigozzi's theory of algebraizable logics or with the use of reduced matrices for L. However, these relations can be naturally formulated when we introduce a new notion of model of a sequent (...) calculus. When applied to a certain natural calculus for L, the resulting models are equivalent to a class of abstract logics (in the sense of Brown and Suszko) which we call distributive. Among other results, we prove that D is exactly the class of the algebraic reducts of the reduced models of L, that there is an embedding of the theories of L into the theories of the equational consequence (in the sense of Blok and Pigozzi) relative to D, and that for any algebra A of type (2,2) there is an isomorphism between the D-congruences of A and the models of L over A. In the second part of this paper (which will be published separately) we will also apply some results to give proofs with a logical flavour for several new or well-known lattice-theoretical properties.
