We investigate agents that have incomplete information and make decisions based on their beliefs expressed as situation calculus bounded action theories. Such theories have an infinite object domain, but the number of objects that belong to fluents at each time point is bounded by a given constant. Recently, it has been shown that verifying temporal properties over such theories is decidable. We take a first-person view and use the theory to capture what the agent believes about the domain of interest (...) and the actions affecting it. In this paper, we study verification of temporal properties over online executions. These are executions resulting from agents performing only actions that are feasible according to their beliefs. To do so, we first examine progression, which captures belief state update resulting from actions in the situation calculus. We show that, for bounded action theories, progression, and hence belief states, can always be represented as a bounded first-order logic theory. Then, based on this result, we prove decidability of temporal verification over online executions for bounded action theories. (shrink)

It is common practice in formal semantics to assume that the context specifies an assignment of values to variables and that the same variables that receive contextually salient values when they occur free may also be bound by quantifiers and λs. These assumptions are at work to provide a unified account of free and bound uses of third person pronouns, namely one by which the same lexical item is involved in both uses. One way to pursue this account is to (...) treat quantifiers and λs as monsters in Kaplan’s sense. We argue that this move should be avoided and explore an alternative route based on the idea that there is a variable assignment coordinate in the context and a variable assignment coordinate in the circumstance of evaluation, with the definition of truth in context identifying them. One fundamental challenge that arises in pursuing a unified account is to explain the difference in the way the gender presuppositions of bound and free pronouns project. The proposal that emerges from the attempt to meet this challenge is a non-indexical account of free third person pronouns and a new conception of the role and structure of assignment functions.

This article proposes a cost-benefit analysis of argumentation, with the aim of highlighting the strategic considerations that govern the agent's decision to argue or not. In spite of its paramount importance, the topic of argumentative decision-making has not received substantial attention in argumentation theories so far. We offer an explanation for this lack of consideration and propose a tripartite taxonomy and detailed description of the strategic reasons considered by arguers in their decision-making: benefits, costs, and dangers. We insist that the (...) implications of acknowledging the strategic dimension of arguing are far-reaching, including promising insights on how to develop better argumentation technologies. (shrink)

En este breve comentario discuto algunos aspectos de la interpretación de la epistemología de Davidson que sugiere Willian Duica en su reciente libro. Luego de una presentación somera del libro me centro en tres asuntos centrales de la interpretación de Duica. En primer lugar, argumento que su lectura de la crítica de Davidson al dualismo esquema/contenido es muy restrictiva y deja abierta la posibilidad de un realismo directo empirista. En segundo lugar, argumento que en su lectura el propio Duica se (...) compromete inadvertidamente con un empirismo de este tipo y, de este modo, su interpretación entra en tensión con el coherentismo de Davidson. Finalmente, discuto algunos aspectos de la interpretación que hace Duica de la tesis davidsoniana de la triangulación. In this short comment I discuss some aspects of William Duica's interpretation of Davidson's epistemology in a recent book. After a brief review of the book, I focus on three central issues of Duica's interpretation. First, I argue that his reading of Davidson's criticism of the scheme/content dualism is too restrictive and leaves open the possibility of an empiricist direct realism. Second, I argue in his reading Duica inadvertently commits himself to an empiricism of this sort and, as a result, his interpretation is in tension with Davidson's own coherentism. Finally, I discuss some aspects of Duica's interpretation of Davidsonian triangulation. (shrink)

The present article aims to utilize some insights from behavioral and happiness economics to discuss the consequences that the introduction of an unconditional basic income to cope with technological unemployment may hold for well-being. The impact of 21st-century technological progress on employment has only just begun to make itself felt and it will take time to realize its full extent. However, the main innovation is already common knowledge: robots are finding their way into the production process. According to several recent (...) contributions, the phenomenon is radically different from past technological revolutions and could generate high levels of unemployment, calling for innovative redistributive public policies. The present article, building on Keynes’ short essay and referring to some of the principles and models of behavioral and happiness economics, focuses on the best-known of these policies, namely provision of an unconditional basic income. A series of factors – loss aversion and hedonic adaptation, the impossibility of escalating to higher-grade consumption behaviors, social interaction in the form of active and passive envy, loss of self-esteem and social stigma – are all likely to have a negative impact on well-being if an unconditional basic income that remains unchanging over time is implemented. A policy mix combining a rising basic income with other measures is therefore proposed. (shrink)

We propose a semantic analysis of the particles afinal (European Portuguese) and alla fine (Italian) in terms of the notion of truth unpersistence, which combines both epistemic modality and constraints on discourse structure. We argue that the felicitous use of these modal particles requires that the truth of a proposition p* fail to persist through a temporal succession of epistemic states, where p* is incompatible with the proposition modified by afinal/alla fine, and that the interlocutors share knowledge of a previous (...) epistemic attitude toward p*. We analyze two main cases, that of plan-related propositions and that of propositions without plans. We also discuss the connections between truth unpersistence and evidentiality. (shrink)

This paper provides a semantic analysis of the particles afinal (European Portuguese) and alla fine (Italian) in terms of the notion of truth unpersistence, which can be situated at the intersection of epistemic modality and discourse structure. In the analysis proposed, the particles are propositional operators and require that the truth of a proposition p* fail to persist through a temporal succession of epistemic states, this proposition being incompatible with the prejacent, and that the interlocutors share knowledge of a previous (...) epistemic attitude toward p*. We analyze two main cases (plan-related and non plan-related propositions) and also show that these particles are indexical to one (or more) epistemic agent(s) and allow for shifts in perspective.

This paper analyzes a non-temporal interpretation of the adverb sempre “always” in European Portuguese and Italian, in which the adverb expresses persistence of the truth of a proposition over time and displays specific contextual constraints (TP-sempre). Despite an overlap in the contexts in which TP-sempre may occur in both languages, we provide data showing that its distribution is not exactly the same in European Portuguese and Italian. In view of these data, we propose that TP-sempre is a modal operator of (...) confirmation in both languages, but that it is more restricted in Italian in that it has a plan presupposition only in this language.

Neste artigo pretendemos examinar a profunda e abrangente influência exercida pela obra de Adam Smith sobre o pensamento de Amartya Sen, especialmente no que concerne ao tema da justiça social, que permeia os escritos de ambos os autores. Primeiramente analisaremos a revisão da obra de Smith, promovida por Sen, para refutar a interpretação, ainda prevalecente, que lança mão de determinados excertos de A riqueza das nações como principal referência na defesa da desregulamentação dos mercados e na isenção do pensamento econômico (...) de qualquer consideração por valores morais, demonstrando como Sen recorre às ideias de Smith para explicar o empobrecimento da economia ao afastar-se da ética. Em seguida nos deteremos na contundente influência do pensamento de Smith sobre a crítica de Sen à teoria da escolha racional mediante sua peculiar formulação da teoria da escolha social, cuja importância foi justamente reconhecida ao lhe valer o prêmio Nobel de economia em 1998.

O Sl 63(62) é de singular importância para a liturgia cristã. Evocando o desejo de Deus que faz com que o ser humano se levante antes da aurora para buscá-lo (v.2), este Salmo tornou-se a oração matutina por excelência, tanto para a liturgia bizantina, que o recita no órthros, quanto para a liturgia romana que, depois da reforma litúrgica do Vaticano II, o reservou para as Laudes do Domingo da I Semana do Saltério. O objetivo do presente artigo é analisar (...) o Sl 63 pelo método da Análise Retórica Bíblica Semítica, com o intuito de estabelecer sua estrutura e de se perceber, assim, seus elementos teológicos mais relevantes. Para cumprir tal finalidade, o artigo divide-se em três partes: tradução do texto; crítica da forma e estabelecimento da estrutura segundo o método da Análise Retórica Bíblica Semítica e, por último, o comentário teológico. O artigo leva conduz o leitor à percepção de que o Salmo possui uma estrutura tripartida. As duas primeiras partes se articulam no âmbito diurno (vv.2-6) e noturno (vv.7-9), onde o salmista manifesta seu desejo por Deus, recorda sua experiência passada e manifesta sua confiança no Senhor. A última parte do Salmo é a imprecação, que evoca um misterioso “eles” (v.10a), conectando-se, assim, com o “tu” evocando no início da oração (v.2a). Ao “eles” amorfo do inimigo, corresponde o manifesto “tu” divino, em quem o salmista confia e cujo “amor” reconhece como sendo melhor que a própria existência (4a). (shrink)

This article explores the ways in which suspects attempt to make putative victims/complainants at least partially responsible for the incidents for which they are investigated, transforming themselves into the victim and the other into the perpetrator. Drawing upon conversation analysis, I examine audio-recorded police interviews for low-level crimes in England and in which suspects have constructed what I refer as counter-denunciations. I argue that suspects accomplish these counter-denunciations through discursive practices that involve, for example (a) contrasting the complainant’s actions with (...) their own innocent conduct; (b) historicizing the event being investigated; and (c) discrediting the complainant’s character—stigmatizing. These practices have in common the suspects’ reliance on the relational and contextual character of the categories ‘offender’ and ‘victim’. (shrink)

Each contribution touches on Teddy’s seminal contributions to the field of imprecise probability, and gives an up-to-date state of the field that cannot be found elsewhere. The title, “a reflection on the foundations of probability and statistics”, calls back to Teddy’s seminal book, “Rethinking the Foundations of Probability and Statistics”, bookends to a career that has made fundamental contributions to (...) the foundations of probability and statistics, and shaped the field of imprecise probability. It is aimed at scholars engaged in probability and statistics. (shrink)

In this sixth issue of Speculations, a serial imprint created to explore post-continental philosophy and speculative realism, a wide range of contemporary philosophical issues pertaining to the contemporary philosophical scene is touched upon, from the continental realism of Tristan Garcia, Graham Harman and Quentin Meillassoux to the 'new realism' of Maurizio Ferraris, from Lacanian and Laurellian speculations to the synthetic philosophy of Fernando Zalamea's mathematics.

O presente artigo tem por objetivo mostrar, desde a psicanálise freudiana, um caminho possível que a leva ao encontro da filosofia de orientação fenomenológica. Em O eu e o isso, de 1923, Sigmund Freud emprega uma nova noção pouco explorada na literatura psicanalítica: o eu-corpo. O escopo de nossa análise delimita-se à interpretação e à explicitação da noção de eu-corpo tal como esta foi apresentada por Freud, confrontando-a com a fenomenologia em Merleau-Ponty e Michel Henry. Para tanto, propomos uma análise (...) em quatro tempos. Inicialmente, evidenciaremos o entendimento de Freud sobre o modelo de psicologia originada em Brentano que tem como um de seus desdobramentos a fenomenologia. Depois, mostraremos como a concepção do isso, segundo o próprio texto de Freud, foi determinante para que ele formulasse uma revisão da primeira tópica e a incorporasse em uma segunda tópica. Por fim, nas últimas duas partes, examinaremos o tratamento dado por Merleau-Ponty e Michel Henry à questão do corpo. Concluímos que é possível o encontro entre a psicanálise e a fenomenologia via a noção de eu-corpo freudiano; contudo, tal condução implicará reformulações em teses centrais da psicanálise. (shrink)

In language learning, learners engage with their environment, incorporating cues from different sources. However, in lab‐based experiments, using artificial languages, many of the cues and features that are part of real‐world language learning are stripped away. In three experiments, we investigated the role of positive, negative, and mixed feedback on the gradual learning of language‐like statistical regularities within an active guessing game paradigm. In Experiment 1, participants received deterministic feedback (100%), whereas probabilistic feedback (i.e., 75% or 50%) was introduced in (...) Experiment 2. Finally, Experiment 3 explored the impact of mixed probabilistic feedback (33% positive, 33% negative, 33% no feedback). The results showed that cross‐situational learning of words was observed without feedback, but participants were able to learn structural regularities of the miniature language only when feedback was provided. Interestingly, the presence of positive feedback was particularly helpful for the learner, promoting more in‐depth learning of the artificial language. (shrink)

In Brazil, the normative landscape around advertising is complex, not the least because of limitations inherent to dispute resolution mechanisms.

Desde los remotos tiempos de la tragedia Ática en Grecia, el teatro es y ha sido siempre movimiento, siendo este una característica esencial de los seres orgánicos, es decir, de los dotados de vida. No obstante, se corre el riesgo de reemplazar su mecánica natural con metafísica, cuando ello no es coherente ni siquiera en hipótesis. Cabe demostrar las disimilitudes del teatro con las doctrinas escolásticas, idealistas, o hinduistas, y su compatibilidad con los átomos, electrones y las leyes de la (...) física, sometiendo sus conceptos al rigor epistemológico. La creación artística nace del psiquismo humano, aun no siendo material en primera instancia, pero ya luego cobra su forma cualitativa definitiva. Para ello atraviesa por varios tipos de censura, tanto física como psicológica, buscando expresarse mediante el lenguaje en que se comunican los distintos géneros dramáticos, dando a conocer su situación de crisis sin retorno, esa que se debate entre crueldad y violencia. Antonin Artaud intrinca al teatro las ideas cabalísticas y no busca contrastarlas con argumentación lógica. La evidencia demuestra que, si es que hay una unidad, esa es la del teatro con lo físico. Lo físico es su verdadero “doble”. Un sucinto pero conciso repaso histórico, bien prodigado de documentación y basado en los preceptos erigidos por el materialismo dialectico, nos dará la certeza de que el teatro pertenece exclusivamente al mundo físico, no solo en la práctica, sino también en esencia, y esta es la materia, siendo solo la metafísica un estadio improbable dentro de ella.

The purpose of this article is to reinforce the alert that the German philosopher Hans Jonas makes in his work Principle responsibility for the imminent possibility of a tragic end of history for humanity if the unpredictable effects arising from the form of action of the liberal political-economic system and the inconsequential advance of the technology that follows are considered. In this intention, we chose as a strategy, to weaken and oppose the Hegelian idea, opposed to Jonah's view, that there (...) would be no cause for alarm because history, in its development, is guided by an immanent and well-intentioned reason that inevitably leads humanity towards the realm of freedom and the absolute spirit. More recently, the American philosopher, economist and political scientist Francis Fukuyama, seeking support in Hegelian thought decreed that history had come to an end with the culmination of the sociocultural evolution of humanity. In this context, we initially seek to present an interpretative analysis of the ideas of Hegel and Fukuyama, and then to make a critique a of this way of thinking, in the light of Hans Jonas' arguments. Finally, it is concluded, through the Jonasian lens, that the story, in addition to not having reached its end, as Fukuyama stated, may also have a quite different ending from that imagined by Hegel. Therefore, one should not disregard the occurrence of the hypothesis of an essential death followed by a physical death of the human race, well before the Hegelian project of freedom has a chance to take place. In doubt, it is better for man to be wary of the existence and of the intention and of the capacity of an imminent reason and to retake in time the reins of his own destiny, through the adoption of a new ethical principle: that of responsibility.

This paper has its roots in qualitative analysis of accounts produced by an Italian serial killer. Theoretical references are related to symbolic interactionism and its developments in the field of psychology and criminology. The whole contribution is aimed to twofold purposes: A) to provide a set of criteria specifically addressed to study deviant action as system of meanings into two related contexts: the single action itself and the whole life history. According this point, paper introduces the concept of “deviant career” (...) and it explains its development and steps; it also provides some psychological social points of views and contributions that scientific works offers. B) to think about potentialities of accounting interviews as powerful tools in clinical practice and empirical research too.Specifically, we discuss narrative about behaviour and life story as a resource in order to take suggestions about meanings, goals and rules of action. It also suggests something about functions that crime discharges in the whole pathway of one's life. Juridical case analysis, run by means of the software ATLAS.ti, is aimed to demonstrate theoretical reasoning proposed. (shrink)

Fábio Alves dos Santos (1954-2013) cursou Pedagogia, Ciências Sociais e Teologia, era Especialista em Filosofia da Religião (PUC Minas), Advogado (PUC Minas) e Mestre em Direito Constitucional (UFMG). Lecionou na PUC Minas como professor de Cultura Religiosa e depois como professor no Curso de Direito, atuando principalmente no Serviço de Assistência Judiciária – SAJ, especialmente cuidado de causas populares como as da ASMARE (Associação dos Catadores de Papel, Papelão e Material Reaproveitável de Belo Horizonte), da Pastoral de Rua, da Pastoral (...) Carcerária, de movimentos de “Sem Casa”, de ocupações e tantos outros grupos. Fábio sofria de grave problema de visão há mais de 15 anos. Quase ficou cego depois de diversas cirurgias de miopia. Isso, porém, não o impedia de seguir seu constante compromisso com as lutas populares. Na última entrevista que concedeu, menos de um mês antes de sua morte (19 de outubro de 2013), depois de duro sofrimento de quase dois anos, no tratamento de um câncer no pâncreas, conta um pouco de sua vida, sua luta e sua percepção de várias realidades, especialmente da Igreja e da pastoral. Militante formado na Teologia da Libertação, de profunda espiritualidade, marcada por traços da religiosidade popular nordestina e comprometida com a libertação, Fábio Alves também buscou em sua vida abrir-se à teologia do pluralismo religioso, especialmente com o Santo Daime, em cuja tradição religiosa chegou a ser “fardado”, mantendo uma profunda atitude espiritual aberta ao diálogo inter-religioso. Sua primeira publicação foi “Começo de mundo novo: sofrimento, luta e vitória dos posseiros de Santana dos Frades”, Sergipe, numa versão popular em 1981 e outra pela Editora Vozes (1990). Fruto de sua dissertação de mestrado, publicou o livro “Direito Agrário: política fundiária no Brasil (1995). Em 2001 saiu seu último livro, uma coletânea de artigos publicados em diversos jornais: “Em defesa da vida”. Num artigo em Horizonte (2004), juntamente com o advogado, amigo e colega Prof. Cristiano de Melo Bastos, discutiu “A prática jurídica na missão da PUC Minas”.

A critical review of the main themes arising out of recent literature on the semantics of ordinary event talk. The material is organized in four sections: (i) the nature of events, with emphasis on the opposition between events as particulars and events as universals; (ii) identity and indeterminacy, with emphasis on the unifier/multiplier controversy; (iii) events and logical form, with emphasis on Davidson’s treatment of the form of action sentences; (iv) linguistic applications, with emphasis on issues concerning aspectual phenomena, the (...) telicity/atelicity distinction, the treatment of statives, and temporal quantification.

We are used to regarding actions and other events, such as Brutus’ stabbing of Caesar or the sinking of the Titanic, as occupying intervals of some underlying linearly ordered temporal dimension. This attitude is so natural and compelling that one is tempted to disregard the obvious difference between time periods and actual happenings in favor of the former: events become mere “intervals cum description”.1 On the other hand, in ordinary circumstances the point of talking about time is to talk about (...) what actually happens or might happen at some time or another. We talk about ‘now’ and ‘then’ in an effort to put some order in our description of what goes on. And since different events seem to overlap in so many different ways, a full account of their temporal relations seems to run afoul of a reductionist strategy. This raises two philosophical questions. The first is whether we can actually go beyond time, as it were, i.e., whether we can take events as bona fide entities and deal with them directly, just as we can deal with spatial entities such as physical bodies or masses without confining ourselves to their spatial representations. This is a controversial issue (though probably not as controversial as it used to be), and ties in with a number of unsettled problems concerning, e.g., the structure of causality or the definition of adequate identity and individuation criteria for events. 2 The second question is whether we can perhaps do without time, i.e., whether we can dispense with time points or intervals as an independent ontological category and focus only on actual or potential happenings, in opposition to the form of reductionism mentioned above—in short, whether we can account for the temporal dimension in terms of suitable relations among events. This is also a highly controversial issue, and relates to the classical dispute concerning relational vs. absolutist conceptions of (space and) time.3 It is this second question that we intend to focus on here..

Focused on city-scale automation, and using self-driving cars (SDCs) as a case study, this article reflects on the role of AI—and in particular, computer vision systems used for mapping and navigation—as a catalyst for urban transformation. Urban research commonly presents AI and cities as having a one-way cause-and-effect relationship, giving undue weight to AI’s impact on cities and overlooking the role of cities in shaping AI. Working at the intersection of data science and social research, this paper aims to counter (...) this trend by exploring the reverse perspective: how do cities affect the development, and expose the present limits, of SDCs? The contribution of this paper is threefold. First, by comparing urban and nonurban environments and thoroughly examining the relationship between computer vision and city-specific sociality and form, it defines machine autonomy/automation as a function of the sociotechnical milieu in which an AI system operates. Second, and related, the paper problematizes the notion of SDCs as autonomous technologies and the role it plays in envisioning contending policy arrangements and technical solutions for achieving full driving automation. Finally, the article offers insight into a materialist and spatialized understanding of AI—namely, not as an abstract quality susceptible to replication within discrete machines, but rather as a distributed property emerging through embodied interactions among a multiplicity of agents (human, non-human, and technological) within/with their environments.

This article, Piaget’s theory of moral development in play behaviour is critically reviewed and framed within the philosophical debate on morality. On this basis, an alternative socio-cognitive model for describing normative evolution in play development is proposed. Special attention is paid to the transition from children’s play to adult games, for the purpose of demonstrating that some relevant features of morality stagnate, rather than progress, during such transition. Finally, some speculations are offered on the connection between moral involution in play (...) and ethical behaviour in life, with reference to contemporary Western societies. (shrink)

Solidarity can be conceived in multiple ways. This article probes possible underlying ontological and normative assumptions of solidarity. In order to conceptually clarify the notion of solidarity, we distinguish between five types of solidarity. We suggest that solidarity is either grounded in the Enlightenment ideas of liberty, or a category of loyalty and allegiance. If the former is the case, solidarity can be justified on rational grounds. If the latter is the case, it is contingent on narratives of historical continuity (...) and a non-rational sense of belonging. Moreover, we show that different types of solidarity can be derived from Anglo-Saxon and continental thought, which hints at different conceptions of community. (shrink)

Populism is widely thought to be in tension with liberal democracy. This article clarifies what exactly is problematic about populism from a liberal–democratic point of view and goes on to develop normative standards that allow us to distinguish between more and less legitimate forms of populism. The point of this exercise is not to dismiss populism in toto; the article strives for a more subtle result, namely, to show that liberal democracy can accommodate populism provided that the latter conforms to (...) particular discursive norms. What the article calls a ‘liberal ethics of populism’ turns out to be closely bound up with a broader ethics of peoplehood, understood as a way of articulating who ‘the people’ are in a way that is compatible with liberal–democratic principles of political justification. Such an ethics, concludes the article, inevitably has a much wider audience than populist political actors: its addressees are all those who seek legitimately to exercise power in the name of the people.

In this essay I will try to demonstrate that the principle of self-determination is based on a formal and individualistic view of liberty rights. I also propose a different perspective that takes into account the relationships rather than the individual. I will show how this result can only be achieved through a different ascription of rights to individuals: in particular, I will try to demonstrate 1) that any social practices express specific values, 2) that these values are the result of (...) historical and cultural circumstances, 3) that they are subject to an ongoing public debate, and finally 4) that only if the individual praxis is consistent with these values can it lead to recognition of rights.

TGiulio Preti, born in Pavia (Italy) in 1911 and dead in Djerba (Tunisia) in 1972, represents one of the most subtle Italian thinkers of the latter half of the twentieth century. After graduating in 1933 discussing a thesis about The Husserl’s historical significance, he connected more and more to the Antonio Banfi’s lesson of critical rationalism and he elected him as his master. Starting from Banfi’s The principles of a reason theory (1927), Preti studied in depth the program of historization (...) of the Kantian transcendental both in books such as Idealism and positivism (1942), and in Praxis and empiricism (1957), in Rhetoric and logic (1968), and then in his numerous essay studies, later collected in fundamental posthumous volumes, Philosophical essays (1976, 2 vol.). Preti’s decisive problem is the following question: how is it possible to historicize human knowledge without a relativization? According to Preti, in order to answer this question, it is necessary to acknowledge the objectivity of scientific knowledge. The objective knowledge mustn’t be confused with an absolute knowledge or, least of all, with a subjective, or toutcourt relative, knowledge. Therefore it is necessary to avoid either opposite poles, but specular, in which the different epistemologicaltraditions of the last century are, on the contrary, stopped. In Preti’s opinion, the objectivity of knowledge arises from the eidetic, linguistic and operative structures, within the limits of which develops a determinate form of human scientific knowledge. In other words: every scientific knowledge, structured into a particularscientific theory and relating to a particular technological heritage, consists of a precise theoretical-practical horizon, that determines, with Husserl’s words, a specific “ontological region”, or, with Bachelard’s words, a specific “ontogenesis”. So Preti recovers the heuristic rule of the Kant’s transcendental reason. Nevertheless, unlike Kant, Preti believes the aprioristic structures of our ideas always have a conventional and historical foundation. In this way, the Kantian a priori changes into an historical and relativistic a priori. Certainly in Kant’s opinion an historical and relativistic a priori would have looked like a “round-square”, an authentic contradiction, a pure logical impossibility. According to Preti, on the contrary, this paradoxical aspect is the true distinctive feature of scientificknowledge objectivity, which has no more any eternal or absolute value, but is always built by men born to die and is always bound to determinate historical forms of civilization. Starting from these assumptions, Preti builds, in this way, a research programme on the possibility to individualize a form of “critic ontologism”, which hasn’t any more connection with the claims and the traditional metaphysical structures of the “Being qua Being”. On the contrary, Preti thinks the only “being” we can rationally talk about is the one constituted within the different cognitive ambits. Philosophy then must be able to develop a “meta-reflection” on different knowledge elaborated by single sciences. According to Preti, in fact, philosophy is the formality of human culture, it is, in other words, a form of self-reflection by the human culture about itself. Therefore philosophy has no more any privileged subject, but it must be always able to reflect, with great theoretical humility, on the different cognitive forms, in order to study languages, structures, methods, extension and limits of the human knowledge. In this way Preti’s “critic ontologism” is a kind of historical-objective transcendentalism, able to study the different configurations of the technical-scientific heritage produced by mankind during his history.
