This paper investigates a limitation of the model of belief and knowledge prevailing in mainstream economics, namely the state-space model. Because of its set-theoretic nature, this model has difficulties in capturing the difference between expressions that designate the same object but have different meanings, i.e., expressions with the same extension but different intensions. This limitation generates puzzling results concerning what individuals believe or know about the world as well as what individuals believe or know about what other individuals believe or (...) know about the world. The paper connects these puzzling results to two issues that are relevant for economic theory beyond the state-space model, namely, framing effects and the distinction between the model-maker and agents that appear in the model. Finally, the paper discusses three possible solutions to the limitations of the state-space model, and concludes that the two alternatives that appear practicable also have significant drawbacks.

The paper reconstructs the connections between the evolution of Patrick Suppes’ measurement theory from 1951 to 1958 and the research in utility analysis he conducted between 1953 and 1957 within the Stanford Value Theory Project. In particular, the paper shows that Suppes’ superseding of the classical understanding of measurement, his endorsement of the representational view of measurement, and his conceiving of an axiomatic version of the latter were prompted by his research in utility analysis.

I examine some behavioural and heuristic models of individual decision-making and argue that the diverse psychological mechanisms these models posit are too demanding to be implemented, either consciously or unconsciously, by actual decision makers. Accordingly, and contrary to what their advocates typically claim, behavioural and heuristic models are best understood as ‘as-if’ models. I then sketch a version of scientific antirealism that justifies the practice of as-if modelling in decision theory but goes beyond traditional instrumentalism. Finally, I relate my account (...) of decision models to the recent controversy about mentalism versus behaviourism, reject both positions, and offer an alternative view. (shrink)

Nash is famous for many inventions, but it is less known that he, simultaneously with Marschak, also was the first to axiomatize expected utility for risk. In particular, these authors were the first to state the independence condition, a condition that should have been but was not stated by von Neumann and Morgenstern. Marschak’s paper resulted from interactions with several people at the Cowles Commission. We document unique letters and personal communications with Nash, Samuelson, Arrow, Dalkey, and others, making plausible (...) that Nash made his discovery independently from the others. (shrink)

The modelling of bounded rationality is currently pursued by approaches that exhibit a wide diversity of methodologies. This special issue collects five contributions that discuss different methodological aspects of these approaches. In our introduction, we map the variety of methodological positions with respect to three questions. First, what kinds of evidence do the respective approaches consider relevant for modelling bounded rationality? Second, what kind of modelling desiderata do the respective approaches focus on? And third, how do the respective approaches justify (...) the normative validity of bounded rationality? To broaden the picture, we not only discusss the five contributions of this issue, but also include relevant positions from the extant literature. (shrink)

In late-nineteenth-century economics, there was an epoch-defining shift from the labour theory of value to the marginal utility theory of value. According to the latter, the economic value of some circumstance (obtaining some good, some service, and so on) is its subjective utility at the margin. Thus, while there is an absolute sense in which I prefer having water to having diamonds, at the present moment I value one more unit of diamonds more than I value one more unit of (...) water. That is why I am willing to pay a higher price for a bowl of diamonds than a bowl of water of the same size, even though water is ‘more valuable’ in a sense. While the marginalists resolved a large array of anomalies that had troubled the labour theory of value, they also believed that utility should be measurable if their theory was to be scientifically respectable. Taking this shift as his starting point, Ivan Moscati has provided a well-written, thorough, and insightful account of the history of utility measurement from 1870 to 1985. (shrink)

Sulla base di una straordinaria analisi dei problemi deontologici riconducibili alla crisi della professione medica, Ivan Cavicchi e un gruppo di lavoro multidisciplinare – promosso e organizzato dall’Ordine dei Medici Chirurghi e Odontoiatri della Provincia Autonoma di Trento, in collaborazione con il programma FBK per la salute della Fondazione Bruno Kessler e il gruppo di Biodiritto del l’Università di Trento – hanno rielaborato le basi concettuali della tradizionale deontologia medica per mettere in condizione gli Ordini dei Medici di riformare (...) il proprio codice deontologico. Si tratta di una vera e propria «rivoluzione» destinata a modificare nei prossimi anni la deontologia nel nostro Paese, a influenzare la redazione dei futuri codici di tutte le professioni medico-sanitarie, ma soprattutto a cambiare radicalmente i rapporti tra medici e cittadini, tra professione e società, tra medicina ed economia. Assumendo il malato come «archè», la proposta di rielaborazione cambia postulati, presupposti, linguaggi, concetti, soluzioni e obiettivi, affrontando problematiche usualmente ignorate dalla deontologia convenzionale. Lo scopo di fondo è definire una nuova figura di medico capace di recuperare il rapporto fiduciario con i malati e con la società e di farsi carico dei problemi di sostenibilità economica che ormai da anni gravano su tutti i sistemi di tutela sanitaria.

We tend to associate Henry David Thoreau with the renunciation of material possessions, projecting onto him our fantasies of a life lived beyond the modern obsession with "things." But Thoreau's practical philosophy held a special place for tools, artworks, Native American artifacts, and a variety of natural phenomena. In Mindprints, Ivan Gaskell focuses on the material items that were important to Thoreau, using them to reveal Thoreau's unique and profound aesthetics of everyday life and the environment. "Mindprint" was Thoreau's (...) term for a material object that has captured the presence of its maker and first user. Thoreau applied the term to ancient stone artifacts and other objects in an effort to capture something of the relationship between material items and humans. For Thoreau, these relationships contribute to the creation of "worlds." By looking at Thoreau's engagement with material worlds through his writings and his practical philosophical experiment at Walden Pond--but also, importantly, via his work as a designer of improved pencils, as a house builder, as a land surveyor, and as a collector--Gaskell reveals the aesthetics at the heart of Thoreau's thinking.

How to Do Things with Myths: A Performative Theory of Myths and How We Got There assembles a radically updated collection of the author's oft-cited publications on myth. Together, they tell how theories of myth have changed and led to a novel "performative" theory of myth.

Et si on appliquait à la philosophie la méthodologie du physicien? L'inexplicable constat des limitations inhérentes à toute réalité expérimentée inciterait à poser en théorie l'hypothèse d'un modèle exempt de ces limitations d'où pourrait procéder la réalité limitée telle que nous la vivons. Et si par déduction on en arrivait à des résultats scientifiquement plausibles, l'aventure à laquelle nous serions alors conviés serait de décoder l'univers comme une anamorphose. Sous la forme d'un dialogue, ce livre met en débat la pensée (...) originale de Pierre Malifaud qui ouvre ensuite à des problématiques plus englobantes. (shrink)

I discuss the role of beauty in physics. Physicists are sometimes described as platonists for their conviction that the fundamental laws are elegant and aesthetic arguments represent an important epistemic tool. After a review of the ideas of Plato and some of the leading figures of modern physics, which suggest that this is indeed the case, I present a list of current aesthetic criteria. I focus on symmetry and unity and demonstrate their increasing relevance in an array of experimentally verified (...) theories. I also deal with an open issue of naturalness as the third criterion. The laws of nature appear increasingly beautiful as we uncover them, and it is important to see if the trend continues in the future. (shrink)

The research deals with the issue of genre hybridization in the novel “Silence – Chronicle of a Killer” written by a contemporary Austrian writer Thomas Raab. An examination of the novel's composition and structure, as a text in motion, has been accomplished in the article. The novel “Silence” is an excellent illustration of how the genre of adventure has been adapted to include elements of science fiction. This novel is a love tale, a rural life saga, a formation narrative, and (...) a psychological thriller all in one. As a fictionalized account of the life of a serial murderer with hypersensitive hearing who became a legend for his mental torment and suffering, it serves both as a biography and a thriller. Novelist Raab uses elements from classic horror novels like Frankenstein, German romantics, in particular, G. Kleist, the tale of Casper Hauser, and detective novels like Friedrich Durrenmatt's "Promise" to tell the story of Casper Hauser's disappearance in his book. A new aesthetic experience may be formed at various degrees of identification ranging from naive perception to higher levels of literary reception. Concentration is required for poetic and philosophical substance. Michel Focalut's nomadism, marginality, and authoritarian power rhetoric have been discussed in this article. The novel's ultimate content has been disclosed as the aphesis torment, emotional sublimation, as the birth of an artwork and, at the same time, death of the author, who exposes discourses, accountable for creating texts that are allocated to him.

When we talk about creation, we use the progressive and verbs of creation as in ‘Mary is building a house’. The modal account of the progressive says that a sentence such as ‘Mary is building a house’ is true just in case Mary eventually builds a house in all worlds in which her house-building proceeds normally. Recently, the modal account has come under fire from those who claim that it over-generates modal entailments and those who think the progressive should be (...) treated as a predicate of events. By properly situating the modal account within a contemporary semantic framework for natural language modals, I argue that it gives the best semantic treatment of the progressive. (shrink)
