Fodor (1998) argues that most lexical concepts have no internal structure. He rejects what he calls Inferential Role Semantics (IRS), the view that primitive concepts are constituted by their inferential relations, on the grounds that this violates the compositionality constraint and leads to an unacceptable form of holism. In rejecting IRS, Fodor must also reject meaning postulates. I argue, contra Fodor, that meaning postulates must be retained, but that when suitably constrained they are not susceptible to (...) his arguments against IRS. This has important implications for the view that certain of our concepts are deferential. A consequence of the arguments I present is that deference is relegated to a relatively minor role in what Sperber (1997) refers to as reflective concepts; deference has no important role to play in the vast majority of our intuitive concepts.

This paper in revised form appears in Facta Philosophica 5:1 (2003) 49­75. It addresses some problems about intensional transitives raised by Moltmann and Zimmerman, corrects some oversights in my paper in The Proceedings of the Aristotelian Society (S.V. for 2002), and adds new material on binary vs. tripartite construals of “relational/notional”, bridge inferences, weakening inferences, and the relevance problem. Its other sections are, like the PASS paper, concerned with the conjunctive force of disjunctive NP complements of intensional transitive verbs: “Smith (...) needs a good lawyer or a friendly judge” on its normal reading implies both “a good lawyer could help him” AND “a friendly judge could help him”. The reading on which “Smith needs a good lawyer or a friendly judge” is implied just by “Smith needs a good lawyer” (and so doesn’t imply a friendly judge could help him) is much less preferred, except when the disjunction is followed by a coda such as “and he doesn’t care which”.

Lasersohn has argued that the use of Russell's analysis of the definite determiner in Montague Grammar, which is responsible for giving the correct prediction in the case of the Temperature Paradox, is also responsible for giving the wrong prediction in the case of the Gupta Syllogism. In this paper I argue against Lasersohn, and show that the problem of the Gupta Syllogism can be solved by making a minor addition to Intensional Montague Grammar. This solution is one that Lasersohn discusses (...) but rejects. I will show that his critique of it is ill-founded. (shrink)

Most philosophers of science nowadays hold a network or postulational view of the meaning of theoretical words. However, there are many nuances to this view, and after explicitly separating them, we show what we take to be wrong with each one. While we reject the postulational view we do not defend its traditional alternatives either; rather we show the pointlessness of insisting on a single source for the meaning of theoretical words. We also point out the shortcomings of (...) Carnap's newest meaning criterion which depends upon a network view. But, again, we suggest not only that this new rendition of the criterion is faulty but also that there is something misguided about any search at all for such a criterion. (shrink)

The standard theory of belief revision was developed to describe how a rational agent should change his beliefs in the presence of new information. Many interesting tools were created, but the concept of rationality was usually assumed to be related to classical logics. In this paper, we explore the fact that the logical tools used can be extended to other sorts of logics, as proved in (Hansson and Wassermann, 2002), to describe models that are closer to the rationality of a (...) real agent.

The aim of interpretation is to capture the past in the future: to capture, not to recapture, first, because the iterative prefix suggests that meaning, which was once manifest, must now be found again. But the postulated author dispenses with this assumption. Literary texts are produced by very complicated actions, while the significance of even our simplest acts is often far from clear. Parts of the meaning of a text may become clear only because of developments occurring long (...) after its composition. And though the fact that an author means something may be equivalent to the fact that a writer could have meant it, this is not to say that the writer did, on whatever level, actually mean it.Alexander Nehamas, professor of philosophy at the University of Pittsburgh, has written articles on ancient Greek philosophy, literary theory, Nietzsche and Thomas Mann.

How did life come into existence on Earth? Although many scientific theories and hypotheses have been drawn, we have not yet been able to provide a detailed answer to this fundamental question. What if intelligent computers would someday be in a condition to postulate their own evolution theory which would explain how they came into the world, how would this theory look like? And how would it stand in comparison to the humans’ theory? Let us suppose that a thousand years (...) from now, intelligent and self-aware computers who, for any reason whatsoever, had lost all contacts with humans, and had continued to self-develop and improve by themselves, slowly began to wonder about how they came into the world? These intelligent computers may eventually develop a coherent theory of evolution, which would seemingly explain their existence. How would their theory stand in comparison to our theory of evolution? Would it be less comprehensive or viable? Taking into consideration the inorganic nature of computers, their relative simplicity compared to the human body, and the closeness of their components to the surrounding inorganic environment, it would not be a surprise if their theory would be more plausible than that of the humans. So, what would this signify and mean to our scientific theories in general? (shrink)

The article aims at organizing multifaceted discourse on the concept of nondirectiveness in the practice of genetic counseling. The analysis of areas where nondirectiveness was invoked and discussed reveals the problematic confusion of different meanings of the term that often leads to false conclusions about the relations between the professional standards and the practice of genetic counseling. The article offers clear and comprehensive description of different approaches to nondirectiveness and various ideas associated with the term. Normative consequences of various meanings (...) attributed to nondirectiveness are explored. The article concludes by presenting important but unsolved problems regarding both theory (the meaning of nondirectiveness and its operational definition) and practice of genetic counseling (the scope and content of the norm of nondirective counseling).

We propose to take issue with a neo-behaviorist upon what might seem to be a minor detail, and about which we are sure that, upon reflection, he would not differ from us. It has to do with the use of the word experience in a basic postulate of behaviorism. Even if by a hair's breadth this implies something categorically different from behavior, then, it seems to us, the essential meaning of behaviorism has been missed.

The keynote of our investigation is suggested by a remark made by Enriques, “the young student of mathematics would indeed look in vain to the classical logic into which he was initiated for an adequate conception of the structure of a deductive science like Geometry let alone for an explanation of the value and meaning of the principles of such a discipline. What are axioms, postulates, definitions? What place do they occupy in the edifice of the theory? What (...) criteria determine their choice and how can we establish whether they are acceptable or not?” These are in general the questions we shall seek to answer in part and then we shall make a special analysis of two of the criteria determining the choice of the axioms.

A proposed measure of voting power should satisfy two conditions to be plausible: first, it must be conceptually justified, capturing the intuitive meaning of what voting power is; second, it must satisfy reasonable postulates. This paper studies a set of postulates, appropriate for a priori voting power, concerning blockers (or vetoers) in a binary voting game. We specify and motivate five such postulates, namely, two subadditivity blocker postulates, two minimum-power blocker postulates, each in weak (...) and strong versions, and the added-blocker postulate. We then test whether three measures of voting power, namely the classic Penrose-Banzhaf measure, the classic Shapley-Shubik index, and the newly proposed Recursive Measure, satisfy these postulates. We find that the first measure fails four of the postulates, the second fails two, while the third alone satisfies all five postulates. This work consequently adds to the plausibility of the Recursive Measure as a reasonable measure of voting power. (shrink)

It is generally recognised that Western civilization is faced with a double threat to its survival, communism from without and disintegration from within. The latter had its beginnings in the Renaissance and the Reformation, both of which had disruptive effects of a size that is now being more or less clearly seen. We also see that there is urgent need to offset the consequences of these movements, and as rapidly as possible. To-day the accent is on co-operation between the diverse (...) elements of Western culture, and a good deal of thought is being given to devising ways and means of bringing the estranged components together, and re-establishing a unity akin to that which formerly existed in Christendom.

In undertaking a discussion of the postulates of empiricism, I am confronted by the necessity of being empirical concerning the very postulates themselves. Were those postulates directly accessible to the average mind it would hardly be necessary to enter upon an analysis the success of which seems but a remote possibility even to one who has spent years in the effort to trace the priceless ingredient of the method of experiment in the cheap madness of scientific success. (...) How these postulates reveal themselves to more than the average mind would, of course, be very difficult for me to surmise, except by an ambitious extrapolation. It would have to be an extrapolation of the kind which telescopes a multitude of small rational steps into one swift unerring instinctive flight to the goal of goals. Yet, though genius with one intuitive glance may perceive the postulates as revelation—why not grant that there may be seers who can contemplate eternal objects unblinkingly?—it would still have to descend to mundane means to inform the average mind of its transcendental perceptions. Must not everyone indeed attend to the demands of the average mind? (shrink)

According to the prevailing opinion of the Kantian scholars, Kants critique of the traditional philosophical theology in the chapter of his Critique of Pure Reason dedicated to the ideal of reason motivated his rejection of transcendental theology in favor of a construction foundeв on postulates of reason. An examination of Kants sistematics of philosophical-theological disciplines reveals nonetheless some changeability of the borderlines of transcendental theology. This means that Kants critical arguments do not necessarily affect all kinds of trancendental theology, (...) and allows us to investigate Kants reflection of the transcendental ideal if reason as a foundation for an alternative version of philosophical ethico-theology which does not need practical postulates. In the first Critique there is no ground for such a construction, because Kant's concept of virtue remains partly naturalistic at that time. The idea of a pure aprioristic ethics of duty as expounded by Kant later furnished the needed conceptual foundation for a concept already prepared in the theory of the ideal, asserting the reality of a transcendental-practical ideal as a prototype of moral will, as humanity in its comprehensively determined moral perfection, as the realm of ethical ends, and lastly, in an anticipation of the prototypical Christology of Kant's late treatise on religion, as the divine human person within us. Compared with this version of transcendental philosophical theology Kants ethico-theology of postulates should be legitimately determined as a form of natural theology. (shrink)

We study whether the probabilistic postulate could be derived from basic principles. Through the analysis of the Strong Law of Large Numbers and its formulation in quantum mechanics, we show, contrary to the claim of the many-worlds interpretation defenders and the arguments of some other authors, the impossibility of obtaining the probabilistic postulate by means of the frequency analysis of an ensemble of infinite copies of a single system. It is shown, though, how the standard form of the probability as (...) the square of the scalar product follows from Gleason's theorem. (shrink)

This book develops an alternative approach to sentence- and word-meaning, which I dub the speech-act theoretic approach, or STA. Instead of employing the syntactic and semantic forms of modern logic–principally, quantification theory–to construct semantic theories, STA employs speech-act structures. The structures it employs are those postulated by a novel theory of speech-acts. STA develops a compositional semantics in which surface grammar is integrated with semantic interpretation in a way not allowed by standard quantification-based theories. It provides a pragmatic theory (...) of truth, a treatment of logically complex discourse as expressive cognitive states, and a background metaphysics in which the world is a totality of logically simple states of affairs. The book also puts forward an account of how intentional states provide the simple, representational foundation for a superstructure of speech-act structures–a system of thoughts–that far outruns the expressive power of the intentional foundation. In short, it provides an account of cognitive foundations of a language and a naturalistic reduction of semantics through an expressive theory of semantic norms. (shrink)

This volume presents a sketch of the Meaning-Text linguistic approach, richly illustrated by examples borrowed mainly, but not exclusively, from English. Chapter 1 expounds the basic idea that underlies this approach—that a natural language must be described as a correspondence between linguistic meanings and linguistic texts—and explains the organization of the book. Chapter 2 introduces the notion of linguistic functional model, the three postulates of the Meaning-Text approach (a language is a particular meaning-text correspondence, a language (...) must be described by a functional model and linguistic utterances must be treated at the level of the sentence and that of the word) and the perspective “from meaning to text” for linguistic descriptions. Chapter 3 contains a characterization of a particular Meaning-Text model: formal linguistic representations on the semantic, the syntactic and the morphological levels and the modules of a linguistic model that link these representations. Chapter 4 covers two central problems of the Meaning-Text approach: semantic decomposition and restricted lexical cooccurrence (≈ lexical functions); particular attention is paid to the correlation between semantic components in the definition of a lexical unit and the values of its lexical functions. Chapter 5 discusses five select issues: 1) the orientation of a linguistic description must be from meaning to text (using as data Spanish semivowels and Russian binominative constructions); 2) a system of notions and terms for linguistics (linguistic sign and the operation of linguistic union; notion of word; case, voice, and ergative construction); 3) formal description of meaning (strict semantic decomposition, standardization of semantemes, the adequacy of decomposition, the maximal block principle); 4) the Explanatory Combinatorial Dictionary (with a sample of complete lexical entries for Russian vocables); 5) dependencies in language, in particular—syntactic dependencies (the criteria for establishing a set of surface-syntactic relations for a language are formulated). Three appendices follow: a phonetic table, an inventory of surface-syntactic relations for English and an overview of all possible combinations of the three types of dependency (semantic, syntactic, and morphological). The book is supplied with a detailed index of notions and terms, which includes a linguistic glossary. (shrink)

The paper attempts to answer a very obstinate fundamental problem—is literary meaning determinable at all? Would it be determinable if it were constructed by the language of the text? Or is this meaning open-ended, constantly deferred or shifted as a result of the very nature of signification? In this paper, I argue that the levels of _dhvani-ṣ Avivakṣitavācya dhvani _ and_ Vivakṣitavācya dhvani_ and their sub-levels are far more comprehensive than the concept of ‘_differance_’, both based on the (...) play of meanings. Ānandvardhana seems to anticipate Derrida in postulating the infinite suggested meaning over and above the expressed literal meaning in the levels of _dhvani_, though the admission of any definite literal meaning itself goes against the deconstructive approach of ‘_differance_’. The paper also deals with the analysing a few literary works with the levels of _dhvani_ and also how meaning of a text is revealed to the _sahrdaya_ (reader). (shrink)

The aim of this paper is to reconstruct and correct one argument in support of the symmetrization postulate in quantum mechanics. I identify the central premise of the argument as a thesis specifying a particular ontic property of quantum superpositions. The precise form of this thesis depends on some underlying assumptions of a metaphysical character. I compare the exchange degeneracy argument with alternative formal arguments for the symmetrization postulate, and I discuss the role and meaning of labels in the (...) symmetric/antisymmetric representations of the states of many particles.

It is widely held that quantum mechanics is the first scientific theory to present scientifically internal, fundamental difficulties for a realistic interpretation (in the philosophical sense). The standard (Copenhagen) interpretation of the quantum theory is often described as the inevitable instrumentalistic response. It is the purpose of the present article to argue that quantum theory doesnot present fundamental new problems to a realistic interpretation. The formalism of quantum theory has the same states—it will be argued—as the formalisms of older physical (...) theories and is capable of the same kinds of philosophical interpretation. This result is reached via an analysis of what it means to give a realistic interpretation to a theory. The main point of difference between quantum mechanics and other theories—as far as the possibilities of interpretation are concerned—is the special treatment given tomeasurement by the “projection postulate.” But it is possible to do without this postulate. Moreover, rejection of the projection postulate does not, in spite of what is often maintained in the literature, automatically lead to the many-worlds interpretation of quantum mechanics. A realistic interpretation is possible in which only the reality ofone (our) world is recognized. It is argued that the Copenhagen interpretation as expounded by Bohr is not in conflict with the here proposed realistic interpretation of quantum theory. (shrink)

In the Critique of Pure Reason, following his elucidation of the ‘postulates’ of possibility, actuality, and necessity, Kant makes a series of puzzling remarks. He seems to deny the somewhat metaphysically intuitive contention that the extension of possibility is greater than that of actuality, which, in turn, is greater than that of necessity. Further, he states that the actual adds nothing to the possible. This leads to the view, fairly common in the literature, that Kant holds that all modal (...) categories, in their empirical applications, are coextensive. I diverge from the common view. First, Kant is not committed to the coextensiveness thesis, understood as above. Instead, he espouses a weaker, epistemological version of the coextensiveness thesis, namely that what we can assert to be really possible is coextensive with what we cognize to be actual. Second, Kant's remarks are not intended to introduce a positive ontological thesis about the extensions of modal categories. Rather, he means to criticize a certain conception of modalities that was prevalent among his rationalist predecessors, i.e., the conception of modalities as various determinations that enter the intensions of concepts of things.

This dissertation contains four independent essays addressing a cluster of related topics in the philosophy of mind. Chapter 1: “Fundamentality Physicalism” argues that physicalism can usefully be conceived of as a thesis about fundamentality. The chapter explores a variety of other potential formulations of physicalism (particularly modal formulations), contrasts fundamentality physicalism with these theses, and offers reasons to prefer fundamentality physicalism over these rivals. Chapter 2:“Modal Rationalism and the Demonstrative Reply to the Master Argument Against Physicalism” introduces the Master Argument (...) Against Physicalism and investigates its crucial premise: the inference from an a priori gap between the physical and consciousness to a lack of necessitation between the two. I argue against the strong form of modal rationalism that underwrites the master argument and offer a more moderate rationalist view. I offer a novel demonstrative reply to the master argument, according to which a connection between conscious experience and demonstratives, not dualism, is the source of the epistemic gap between consciousness and the physical. Chapter 3: “Conceptual Mastery and the Knowledge Argument” argues that Frank Jackson’s famous anti-physicalist knowledge argument featuring Mary, a brilliant neuroscientist raised in a black and white room, founders on a dilemma. Either (i) Mary cannot know the relevant experiential truths because of trivial obstacles that have no bearing on the truth of physicalism or (ii) once the obstacles have been removed, Mary can know the relevant truths. Chapter 4: “Toward a Theory of Conceptual Mastery” investigates the question “Under what conditions does a thinker fully understand, or have mastery of, a concept?” I argue against three views of conceptual mastery, according to which conceptual mastery is a matter of holding certain beliefs, being disposed to make certain inferences, or having certain intuitions. I propose and respond to objections to my own “meaning postulate view” of the conditions under which a thinker has mastery of a concept. (shrink)

The globally generated concepts of environment and sustainability are fast gaining currency in international business discourse. Sustainability concerns are concurrently becoming significant to business planning around corporate social responsibility and integral to organizational strategies toward enhancing shareholder value. The mindset of corporate managers is a key factor in determining company approaches to sustainability. But what do corporate managers understand by sustainability? Our study explores discursive meaning negotiation surrounding the concepts of environment and sustainability within business discourse. The study is (...) based on qualitative interpretive research drawing from symbolic interactionism which postulates that meaning in discourse is an essentially contested domain dependent upon negotiation in the Habermasian tradition of mutually respectful dialogue. Data from semi-structured intensive interviews of a small sample of senior corporate managers was analyzed to examine how corporate elites in India frame their approach to sustainability issues and respond to external pressures for deeper corporate responsibility. The findings point to the existence of a distinctively local narrative with strong potential for the discursive negotiation of personal and collective understanding of ethical and socio-cultural values that may help internalize broader sustainability considerations into corporate decision-making processes.

This paper deals with a foundational aspect of Integrated Information Theory of consciousness: the nature of the relation between the axioms of phenomenology and the postulates of cause-effect power. There has been a lack of clarity in the literature regarding this crucial issue, for which IIT has received much criticism of its axiomatic method and basic tenets. The present contribution elucidates the problem by means of a categorial analysis of the theory’s foundations. Its main results are that: IIT has (...) a set of nine fundamental concepts of reason, called categories, which constitute its categorial lexicon and through which it formulates a system of principles incorporating the axioms, the postulates, and the central identity; and the connection between the axioms and postulates is grounded by their common root in this categorial lexicon, the categories of which find their justification by means of a phenomenological and transcendental deduction. Some further results are the unique origin of axioms and postulates in the categories; the distinction between conceptual and formalized postulates; a clarification of the uniqueness problem of categorial lexica in general; and an IIT account of objectivity by explicating how the physical is defined by means of categories. All of this is put to use against various criticism targeting IIT’s theoretical core. If successful, the proposed interpretation illuminates a central issue in the contemporary study of consciousness and contributes to an environment of mutual understanding between defenders and critics of the theory.

During the past three decades, there has been an ongoing debate on the quality of health care. Defining quality is an important part of it. This paper offers a review of definitions and a conceptual analysis in order to understand and explain the differences between them. The analysis results in a semantic rule, expressing the meaning of quality as an optimal balance between possibilities realised and a framework of norms and values. This rule is postulated as a formal criterion (...) of meaning, e.g. when (correctly) applied people understand each other. The rule suits the abstract nature of the term quality. Quality doesn't exist as such. It is constructed in an interaction between people. This interaction is guided by rules in order to transfer information, e.g. communicate on quality. The rule improves our ability to discuss the debate on quality and to develop a theory grounding actions such as quality assurance or quality improvement. (shrink)

In the present paper, I analyze the complex relationship of tension between Critical Theory and phenomenology from a sociological-theoretical perspective. I start from two theses. The first one is that one of the primary reasons for the antagonism between these two paradigms lies in their ideal-typically opposed assessments of the role of ‘meaning-adequacy’ in social research. The second one is that in recent years, there has been a strong rapprochement of Critical Theory with (social) phenomenology. This shift, fundamentally embodied (...) in Hartmut Rosa’s work, can be understood as the culminating point of a progressive turn towards meaning-adequacy within the Frankfurt School. In order to unfold these two theses, I will proceed in three steps. First (1), I will present the main outlines of the relationship of tension between the two traditions from both a historico-intellectual and a systematic perspective. Second (2), I will focus on the contemporary readings of the Schutzian notion of ‘meaning-adequacy’ and discuss their value for better understanding the historical opposition between the two paradigms, as well as their recent rapprochement. Third (3), I will sketch the key features of Rosa’s sociology of world-relations, understood as a phenomenological Critical Theory that shows a strong commitment to a radicalized version of the meaning-adequacy postulate.

A unified axiomatic theory that embraces both mechanics and thermodynamics is presented in three parts. It is based on four postulates; three are taken from quantum mechanics, and the fourth is the new disclosure of the existence of quantum states that are stable (Part I). For nonequilibrium and equilibrium states, the theory provides general original results, such as the relation between irreducible density operators and the maximum work that can be extracted adiabatically (Part IIa). For stable equilibrium states, it (...) shows for the first time that the canonical and grand canonical distributions are the only stable distributions (Part IIb). The theory discloses the incompleteness of the equation of motion of quantum mechanics not only for irreversible processes but, more significantly, for reversible processes (Part IIb). It establishes the operational meaning of an irreducible density operator and irreducible dispersions associated with any state, and reveals the relationship between such dispersions and the second law (Part III).

In this paper we suggest that Duffley’s sign-based semantics rests on two main claims: a methodological one and an ontological one. The methodological one is the analysis of corpora and the ontological one is the postulate of mental content. By adopting a linguistic enactivist perspective with a Wittgensteinian twist, we endorse Duffley’s methodological claim and suggest that a sign-based semantics doesn’t have to rely on mental content if it takes into account the conception of meaningful material engagement in cognitive archeology (...) and its development into sign-using as an enactive capacity.

This chapter considers the phenomenon of meaning from the perspective of Chomsky’s ‘I-linguistics’ and his empirical postulation of the ‘language faculty’. After a sketch of that model, the question is raised as to how meaning should be incorporated within it. In accord with the use-theoretic perspective of this book, an answer is developed whereby the association of I-sounds with I-meanings is achieved by virtue of the conceptual roles of those I-sounds, i.e., their basic acceptance-properties. It is shown that (...) this picture compares favourably with various alternatives, including those suggested by Fodor’s mentalese, Davidson’s view of compositionality, naturalizations of the reference relation, and by Chomsky-style explicitly-represented definitions.

The received view of Martin Heidegger’s work is that he leaves little room for reason in the practice of philosophy or the conduct of life. Citing his much-scorned remark that reason is the “stiff-necked adversary of thought”, critics argue that Heidegger’s philosophy effectively severs the tie between reason and normativity, leaving anyone who adheres to his position without recourse to justifying reasons for their beliefs and actions. Transcending Reason is a collection of essays by leading Heidegger scholars that challenges this (...) view by exploring new ways to understand Heidegger’s approach to the relationship between reason, normativity, and the philosophical methodology that gives us access to these issues. The volume points to Heidegger’s novel approach to reason understood in terms of what he calls Dasein’s ‘transcendence’—the ability to occupy the world as a space of normatively structured meanings in which we navigate our striving to be. By examining the strengths and weaknesses of this new and innovative take on Heidegger’s philosophy, this collection considers the possibility that he does not sever but rather reconceives the relation between reason and normativity. -/- .

In the following article, the author offers an interpretation of George Canguilhem’s thinly articulated concept “biological meaning.” As a way into the problem, the article begins with the question: how does “biological meaning” differ from other forms of meaning? That is to ask, if we are to hold that the mere physical/chemical mode of being of a stone differs from the biological mode of being of an organism, how do they differ in their meaning? In an (...) effort to supply an answer to this question, our author postulates that, when we consider the lived circumstances of the organism, the existential situation of living beings, their biological facticity, then we intuit a fundamental difference in the mode of being of the motions of billiard balls and those of organisms. Moreover, through the investigation into, on the one hand, the motions that take place in a living milieu and, on the other hand, the form of potentiality inherent in what we might call the motions of adaptation, the author offers a preliminary description of a meaning that might be uniquely biological.

In 1940, Wolfgang Metzger began a profound reflection on the meaning of the phenomenological approach to Gestalt psychology, which had its starting point in the rejection of what he called the “Eleatic” or “Eleatic–Rationalistic Postulate,” that is, the notion that, in his opinion, had dominated Western scientific and philosophical thought of the past centuries, according to which any assertion about the state of things that could lead to self-contradictory conclusions had to be considered unfounded. On the basis of this (...) rejection and with exclusive reference to access to experiential data, Metzger proposed to distinguish five meanings of reality: (1) the physical or experiential world; (2) the intuitive or experienced world; (3) the experienced world (met, Angetroffen) in contrast to the represented world; (4) the something or fullness in contrast to emptiness or nothingness; (5) the real in contrast to the apparent. For Metzger (1950), this concept, although primarily related to perception, has far-reaching implications for our conception of others and of society. We question here the validity of Metzger’s concept, its explanatory significance, and its relation to other phenomenological concepts, such as that of Merleau-Ponty. (shrink)

I trace the development of arguments for the consistency of non-Euclidean geometries and for the independence of the parallel postulate, showing how the arguments become more rigorous as a formal conception of geometry is introduced. I analyze the kinds of arguments offered by Jules Hoüel in 1860-1870 for the unprovability of the parallel postulate and for the existence of non-Euclidean geometries, especially his reaction to the publication of Beltrami’s seminal papers, showing that Beltrami was much more concerned with the existence (...) of non-Euclidean objects than he was with the formal consistency of non-Euclidean geometries. The final step towards rigorous consistency proofs is taken in the 1880s by Henri Poincaré. It is the formal conception of geometry, stripping the geometric primitive terms of their usual meanings, that allows the introduction of a modern fully rigorous consistency proof. (shrink)
