Social networks can influence people’s behaviour and therefore it is assumed that central individuals in social networks, also called “opinion leaders”, play a key role in driving change in agricultural and food systems. I analyse the outcomes of an intervention (that encouraged Sulawesi smallholder farmers to take a specific action toward improving the health of their cocoa trees) to assess the impact of engaging opinion leaders in agricultural programs that aim to change farmers’ practices. The intervention has been implemented through (...) (a) 18 opinion leaders identified by interviews and a social network survey of 1885 cocoa farmers; and (b) 18 randomly selected farmers who were not central in local social networks. The obtained social networks and statistical data were quantitatively analysed and the results were interpreted with input from the field staff. Contrary to expectations, the highly socially central opinion leaders were not more effective in promoting the initiative in their communities. On average, randomly selected low-centrality farmers convinced almost twice as many of their peers to take the recommended action as compared to the identified opinion leaders (17.1 versus 8.6) but the variation within the random group was also significantly higher. Importantly, while the identified opinion leaders were mostly senior men, women performed better in influencing others into taking action even when their centrality in local social networks of agricultural advice was lower. I discuss the implications of the conventional selection of perceived opinion leaders as model farmers for achieving sustainable and equitable change at scale in agriculture and propose practical alternatives.

This paper addresses the ontological status of the body in the context of bodily practices in body-oriented disciplines, such as sport training, dance, and physiotherapy. Following Descartes’, Huss...

Between the zone of certainty beyond all doubt and the zone of incomprehensible uncertainty, the sources of which are nothing but chance, we need to use solid results from a vast interdisciplinarity. We wish to give here a sense of the factors in play and the state of the debate and advance in the territory of how interdisciplinarity may help to solve problems which are common in many areas of knowledge. Chaos and complexity certainly put limits on what we can (...) know. High complexity, asymmetry and/or non-linearity are universal types of imprecision. Can hazard have purpose and direction?The idea is that the more effort we put into project design to cover as many details and possible consequences as possible we can grasp in our in-depth analysis aiming to create the project (in art or science or society), the greater the chances that the random occurrence of the unpredictable event will settle on the project's purpose and direction and not on contrary to them. There is no vicious circle here. This kind of method can explain many good results already obtained in such circumstances. Simplicity, beauty, rationalistic optimism, are features of unshakeable scientific results We may call this feature of scientific theory or art _uniqueness. _Uniqueness is strongly correlated with _essentialization. _Science is working in that sense: to simplify a phenomenon to its essence in order to study it easily without losing anything important in the analysis. That is _essentialization. _Why and how complex systems move to the edge of chaos? And what do they do to stay there? They are in constant struggle to create or keep order in complexity. That is the pattern of self-organization, the specific feature of human nature. That is why our action is meant to build resilience to deal better with unpredictable events and prevent the emergence of a critical threshold. Uncertainty, indeterminacy, randomness, and contradictions appear, not as non-essential substances of debate to be eliminated by explanation, but as everlasting ingredients of our conception of reality. There are compelling reasons to believe that it is impossible to make accurate, nontrivial predictions concerning human behavior. Logic and reason are and remain priority, but unpredictability forces us to imagination and creative thinking. Indeed we are confronted with a new human landscape. The anomalies become the new normal. (shrink)

Large language models (LLMs) represent the currently most relevant incarnation of artificial intelligence with respect to the future fate of democratic governance. Considering their potential, this paper seeks to answer a pressing question: Could LLMs outperform humans as expert advisors to democratic assemblies? While bearing the promise of enhanced expertise availability and accessibility, they also present challenges of hallucinations, misalignment, or value imposition. Weighing LLMs’ benefits and drawbacks compared to their human counterparts, I argue for their careful integration to augment (...) democracy’s ability to address complex policy issues. The paper posits that time-tested democratic procedures like deliberation and aggregation by voting provide safeguards effective against both human and machine advisor imperfections. Additional protective measures include custom LLM training for the advisory role, boosting representatives’ competencies in query formulation, or implementation of adversarial proceedings in which LLM advisors could debate each other and provide dissenting opinions. These could further mitigate the risks that LLMs present in advisory roles and empower human decision-makers toward increased autonomy and quality of their collective choices. My conceptual exploration offers a roadmap for the co-evolution of AI and democratic institutions, setting the stage for an empirical research agenda to finetune the implementation specifics.

Despite their flaws, large language models (LLMs) deserve a fair chance to prove their mettle against human experts, who are often plagued with biases, conflicts of interest, and other frailties. For epistemically unprivileged laypeople struggling to access expert knowledge, the accessibility advantages of LLMs could prove crucial. While complaints about LLMs' inconsistencies and arguments for human superiority are often justified (for now), they distract from the urgent need to prepare for the likely scenario of LLMs' continued ascent. Experimentation with both (...) the capabilities and institutional architecture of LLMs is necessary. Neither tech-bashing nor excessive gatekeeping will suffice. As LLMs are here to stay and they keep improving, it is high time we started thinking about how to navigate the impending wave of their proliferation. (shrink)

Eco-phenomenology is a young branch of contemporary phenomenology and environmental ethics that attempts to put aside all preconceptions burdening the relationship between humans and nature, to describe it purely on the basis of how it appears phenomenologically, and to draw ethical implications that could contribute to solving the ecological crisis. Authors inspired by Levinas’ ethics play an important role in this project, asking whether it could be extended to non-human beings. The article addresses two of them in particular: it shows (...) how Ch. Diehm – who sees the core of Levinas’ ethics in sensitivity to the suffering of the vulnerable body – succeeded in comparison to his predecessor S. Benso and her ethics of things, but also marks the limits of his attempt, thus indicating what remains a challenge for Levinas-inspired eco-phenomenology in the future. (shrink)

People have always tried to make predictions; they are necessary and useful, but very often they commit obvious errors, which have negative consequences on decision-making. Prediction errors are in some cases, not few, unavoidable, because the world itself is unpredictable, subject to chance (or randomness in mathematics). Chance is a property of nature. The causes of random events are physically determined, but so numerous and complex that they (the events) are unpredictable. Science is not about certainty. Human knowledge itself is (...) not certain. We can only have provisional truths. Therefore, we must manage to reach a state of accommodation with uncertainty and unpredictability. The complexity of natural phenomena generates events that we cannot control through theoretical modeling precisely because of the ignorance of the causal mechanisms, which exist in their privacy but have not (yet) been revealed by the data and observations at our disposal. We have, on the one hand, life experience taken over and assimilated and established in society and, on the other hand, experience gained from real life. Norm and chance follow each other rather chaotically. The duration of validity of a norm and the moment of occurrence of the random event are unpredictable. However, norms and events coexist in our consciousness. Order and predictability are born (formed and exist) from rules; chance and unpredictability are born from the lack of rules. The highest truths, recognized as such by society cannot be transposed into the life of society only by the force of reason. It is imperative that they are reinforced and embedded in the social behavior of all citizens. Rules are needed. Without rules there is no freedom. (shrink)

This monograph presents a general theory of weakly implicative logics, a family covering a vast number of non-classical logics studied in the literature, concentrating mainly on the abstract study of the relationship between logics and their algebraic semantics. It can also serve as an introduction to algebraic logic, both propositional and first-order, with special attention paid to the role of implication, lattice and residuated connectives, and generalized disjunctions. Based on their recent work, the authors develop a powerful uniform framework for (...) the study of non-classical logics. In a self-contained and didactic style, starting from very elementary notions, they build a general theory with a substantial number of abstract results. The theory is then applied to obtain numerous results for prominent families of logics and their algebraic counterparts, in particular for superintuitionistic, modal, substructural, fuzzy, and relevant logics. The book may be of interest to a wide audience, especially students and scholars in the fields of mathematics, philosophy, computer science, or related areas, looking for an introduction to a general theory of non-classical logics and their algebraic semantics.

The possibility of performing germline modifications on currently living individuals targets future generations’ health and well-being by reducing the diversity of the human gene pool. This can have two negative repercussions: reduction of heterozygosity, the latter being associated with a health or performance advantage; uniformization of the genes involved in reproductive recombination, which may lead to the health risks involved in asexual reproduction. I argue that germline interventions aimed at modifying the genomes of future people cannot be ethically justifiable if (...) there is no possibility of controlling the intervention either by reversing or altering it, whenever need demands it. This argument is challenged on six different grounds: safety, population versus individual focus, spontaneous mutations, exceptionalism, the intentional pursuit of genetic diversity through germline interventions, and harm reduction potential.

Analyzing different philosophical and theological components of Aquinas’s view regarding the relation between human agency and divine providence, the monograph shows this view to be compatibilist, based on a determinist conception of causation and an aristocratic understanding of goodness.

The article develops a critique of John Deely’s ontological realism, specifically in its relevance for the project of global semiotics. Deely, whose theorizations rely heavily on the pre-modern philosophical systems of Thomas Aquinas and the Latin scholastics, has made the most sustained attempt to give philosophical grounding to Charles Peirce’s famous intuition that “all this universe is perfused with signs, if it is not composed exclusively of signs”. The critique developsalong two main lines. Firstly, I contend that Deely’s account of (...) onto logical relations is unsatisfactory, for it assumes the very fact it promises to demonstrate: the identity between patterns of physical events, on one hand, and patt erns of thought, on the other. As it is never adequately explained what it means for the former to be identical with the latter, the mediating term – “ontological relation” – remains highly problematic. Secondly, I argue that even if this ontological paradigm is allowed to stand as proposed, it still fails to bridge the gap between the so-called “natural” signs and human-specific, language-based signification; for, as it posits a unity between the stipulable and the non-stipulable sign, the argument falls into a performative contradiction.

The article presents a critical semantic analysis of the so-called analytical truths as they were discussed by R. Carnap and building on some new empirical data that are not fully satisfactorily explained by Carnap’s theory. A theoretical reconstruction of Carnap’s theory of analytical truths is proposed. It is demonstrated how his understanding of analytical truths, as statements that are true in all possible worlds and amenable to a quite obvious definition on a par with the concepts of sense (meaning) and (...) synonymy, applies exclusively to artificial languages of logic. Therefore, Carnap’s theory remains unreachable for the well-known criticism of W. Quine, who, in turn, pointed out the difficulties in defining these concepts for natural languages. A theoretical reconstruction of Carnap’s explication of the mentioned concepts in the theory of meaning for natural languages is carried out. The connection of Carnap’s approach with the perspective of contemporary formal semantics is established. Subsequently, problematic cases and the difficulties they pose for Carnap’s concept are examined. An explanation is proposed for analytical truths as containing in their logical form an (unpronounced) quantifier over possible worlds (situations). (shrink)

How can one freely act contrary to one’s better judgement about what is right? Since antiquity, this question has attracted attention of many ethicists and theorists of action as the “problem of akrasia”. On a traditional and still influential view akrasia happens when some irrational tendencies, emotions and desires override the rational part of one’s soul and cause them to act in a way which contradicts their rational beliefs about what is good and desirable. In this paper, we aim to (...) show that the view of akrasia as a matter of practical irrationality doesn’t provide an adequate tool for understanding the complex nature of akrasia, since it obstructs an insight into the rational and social dimension of akrasia. We will argue that akrasia, far from being only an individual phenomenon, concerns also the action of broader social and political entities. We will introduce the notion of socio-political akrasia and demonstrate the seriousness of this phenomenon by analysing the case of (in)action of contemporary governments in the context of the climate crisis. Finally, we will conclude by offering a perspective on how to prevent socio-political akrasia. (shrink)

This edition of The Psychology of Man's Possible Evolution includes a lecture, not previously published, in which Ouspensky givers some details of the "School of the Fourth Way," with which he was connected, and an account of some of its fundamental principles, methods, and rules. The psychology Ouspensky sets forth in this introductory lectures has existed in one form or another for thousands of years and, unlike modern psychology, studies man from the point of view of what he may become. (...) Once a man realizes how little control he has over his reactions to external circumstances and internal stimuli, he may wish to find a way to becomoe free of this mechanical way of living. Ouspensky describes how a man must work simultaneously on his knowledge and his being to find inner unity and why although his development depends on his own efforts, this is very difficult to achieve without guidance from a "School.".

First the Branching Space-time and Branching Continuations mod-els are briefly presented. We compare their properties with the traditional definition of a Flow of Time from physics and we point out the difficulties of it in relativistic time. A solution of a Flow of Time in the given models is then proposed.

Advances in artificial intelligence and robotics stand to change many aspects of our lives, including our values. If trends continue as expected, many industries will undergo automation in the near future, calling into question whether we can still value the sense of identity and security our occupations once provided us with. Likewise, the advent of social robots driven by AI, appears to be shifting the meaning of numerous, long-standing values associated with interpersonal relationships, like friendship. Furthermore, powerful actors’ and institutions’ (...) increasing reliance on AI to make decisions that may affect how people live their lives may have a significant impact on privacy while also raising issues about algorithmic transparency and human control. In this paper, building and expanding on previous works, we will look at how the deployment of Artificial Intelligence technology may lead to changes in identity, security, and other crucial values. We will discuss what challenges we may face in the process, while critically reflecting on whether such changes may be desirable. Finally, drawing on a series of considerations underlying virtue ethics, we will formulate a set of preliminary suggestions, which—we hope—can be used to more carefully guide the future roll out of AI technologies for human flourishing; that is, for social and moral good.

Do people fall for online disinformation, or do they actively utilize it as a tool to accomplish their goals? Currently, the notion of the members of the public as victims of deception and manipulation prevails in the debate. It emphasizes the need to limit people’s exposure to falsehoods and bolster their deficient reasoning faculties. However, the observed epistemic irrationality can also stem from politically motivated reasoning incentivized by digital platforms. In this context, the readily available disinformation facilitates an arms race (...) in loyalty signaling via a public endorsement of fanciful partisan claims. Such a signaling arms race appears capable of derailing democratic decision-making perhaps more effectively than any known reasoning deficiency. Appreciating the role of an instrumentally rational cost-benefit calculus in triggering the disinformation crisis thus appears vital. Examining these themes, the paper contributes to the current debates in political epistemology and democratic theory. (shrink)

Procedural justifications of democracy emphasize inclusiveness and respect and by doing so come into conflict with instrumental justifications that depend on voters’ competence. This conflict raises questions about jury theorems and makes their standing in democratic theory contested. We show that a type of no-regret learning called meta-induction can help to satisfy the competence assumption without excluding voters or diverse opinion leaders on an a priori basis. Meta-induction assigns weights to opinion leaders based on their past predictive performance to determine (...) the level of their inclusion in recommendations for voters. The weighting minimizes the difference between the performance of meta-induction and the best opinion leader in hindsight. The difference represents the regret of meta-induction whose minimization ensures that the recommendations are optimal in supporting voters’ competence. Meta-induction has optimal truth-tracking properties that support voters’ competence even if it is targeted by mis/disinformation and should be considered a tool for supporting democracy in hyper-plurality.

The paper outlines the understanding of emergence in Ontic Structural Realism of James Ladyman (and his co-author Ross). First, the notion of emergence is explored, surveying the various distinctions associated with it (ontological vs. epistemological, diachronic vs. synchronic, weak vs. strong). It turns out that Ross and Ladyman’s notion of emergence is that of weak epistemological emergence compatible with ontic reduction. Particular notions of emergence are associated with the objection embodied in the Generalized Causal Exclusion Argument. The latter is sketched (...) and the solution of Ross and Ladyman is presented: first, in general, the notion of weak emergence is not threatened by this objection. Causal reduction associated with it ensures that there are no competing causal explanations, so no overdetermination arises. Second, there is a peculiar feature of Ross and Ladyman’s theory; namely, there is no causation on the fundamental level, only pattern dynamism. Causation emerges only on higher levels of special sciences. Hence, there is no problem of causal overdetermination. (shrink)

In the last few decades many formal systems of fuzzy logics have been developed. Since the main differences between fuzzy and classical logics lie at the propositional level, the fuzzy predicate logics have developed more slowly (compared to the propositional ones). In this text we aim to promote interest in fuzzy predicate logics by contributing to the model theory of fuzzy predicate logics. First, we generalize the completeness theorem, then we use it to get results on conservative extensions of theories (...) and on witnessed models. (shrink)

This study explores the phenomenon of the so-called “third reading” of propositional attitude reports. This reading, which was originally explored in the dissertation of J. Fodor (1973) and has since become one of the significant problems in the formal semantics of natural languages, differs from the more well-known de re and de dicto readings by being an intermediate case. If the de re interpretation can be referred to as transparent specific, and the de dicto interpretation as opaque non-specific, then the (...) third reading is transparent non-specific. Fodor's standard solution has been the subject of much discussion in the literature and has given rise to a series of widely accepted counterexamples that are thought to demonstrate the limitations of Fodor's solution. At the same time, alternative approaches to the explication of these readings also suffer from formal shortcomings (for example, some of them did not satisfy the requirement of meaning compositionality, which is a basic requirement in formal semantic literature). This study points out that the analysis of all complex cases of the third reading did not fully take into account their syntactic structure. This remained unnoticed due to the ellipsis in many of these cases. It is shown that a restoration of the ellided syntactic structure makes it possible to analyze all hard cases as basic ones using the classical standard analysis proposed by Fodor supplemented by the principles of admissibility of substitution of L-equivalent expressions in intensional contexts (known since G. Frege and R. Carnap). In the final part of the work, it is demonstrated how exactly the main complex cases of the “third reading” are explicated in terms of the standard approach. (shrink)

Can one extend crisp Peano arithmetic PA by a possibly many-valued predicate Tr(x) saying “xis true” and satisfying the “dequotation schema”for all sentences φ? This problem is investigated in the frame of Łukasiewicz infinitely valued logic.

The paper proposes a synthesis between human scientists and artificial representation learning models as a way of augmenting epistemic warrants of realist theories against various anti-realist attempts. Towards this end, the paper fleshes out unconceived alternatives not as a critique of scientific realism but rather a reinforcement, as it rejects the retrospective interpretations of scientific progress, which brought about the problem of alternatives in the first place. By utilising adversarial machine learning, the synthesis explores possibility spaces of available evidence for (...) unconceived alternatives providing modal knowledge of what is possible therein. As a result, the epistemic warrant of synthesised realist theories should emerge bolstered as the underdetermination by available evidence gets reduced. While shifting the realist commitment away from theoretical artefacts towards modalities of the possibility spaces, the synthesis comes out as a kind of perspectival modelling. (shrink)
