I have two aims in this paper. First, I argue that, in Aristotle’s theory of the four causes, there is a basic and common feature by which all causes are causes: they all work in a triadic framework in which they explain why a given attribute holds of a given underlying thing. Secondly, I argue against a version of “compatibilism” according to which each kind of cause is complete in its own domain and does not compete with any other kind. (...) I claim that there are priority relations according to which some kinds of cause are subordinated to others, even if these relations do not hold in every cases. (shrink)

I discuss Aristotle's treatment of essence and definition in Metaphysics VII.4. I argue that it is coherent and perfectly in accord with its broader context. His discussion in VII.4 offers, on the one hand, minimal criteria for what counts as definition and essence for whatever kind of object, but also, on the other hand, stronger criteria for a primary sort of definition and essence—and thereby it serves the interest of book VII in pointing to the explanatory power of the essence (...) of composite substances.

I review recent work on Phenomenal Conservatism, the position introduced by Michael Huemer according to which if it seems that P to a subject S, in the absence of defeaters S has thereby some degree of justification for believing P.

The controversy that between 1908 and 1912 saw Benedetto Croce and Giovanni Gentile opposed, on one side, and Federigo Enriques, on the other, did not actually have a conclusive episode, but its end was perceived, for its results on culture, on society and teaching in Italy, as a "defeat" of Enriques. A more careful examination of the events and of the historical context in which it took place seems, however, to clearly demonstrate that we can speak not of a personal (...) defeat of the great mathematician from Livorno, but rather of a defeat of the commendable attempts at cultural and social modernization of Italy in an international perspective, of which Enriques was not the only actor but certainly the most exposed. Such intentions were crushed by the myopic provincial conservatism of the Italian neo-idealism, favored by the fascist regime, concerned only with affirming in the world an alleged autarkic national cultural superiority, based on the traditional literary-humanistic culture, ignoring the progress of the new technical-scientific thought, placed in an international context. Sunto_ La polemica che dal 1908 al 1912 vide contrapposti da una parte Benedetto Croce e Giovanni Gentile e dall’altra Federigo Enriques non ebbe, in realtà, un episodio conclusivo, ma la sua fine è stata percepita, per i suoi esiti sulla cultura, sulla società e sull’insegnamento in Italia, come una “sconfitta” dell’Enriques. Un esame più attento delle vicende e del contesto storico nel quale si svolse sembra, invece, dimostrare chiaramente di poter parlare non di una sconfitta personale del grande matematico livornese, quanto piuttosto di una sconfitta dei lodevoli tentativi di ammodernamento culturale e sociale dell’Italia in una prospettiva internazionale, di cui Enriques non fu l’unico attore ma sicuramente quello più esposto. Tali propositi furono schiacciati dal miope conservatorismo provinciale del neoidealismo italiano, favorito dal regime fascista, preoccupato unicamente di affermare nel mondo una pretesa superiorità culturale nazionale autarchica, basata sulla tradizionale cultura letterario-umanistica, ignorando il progresso del nuovo pensiero tecnico-scientifico, per sua natura, invece, inserito in un contesto internazionale.

This chapter discusses the structure of our temporally extended agency. We do not have the power to act directly at a distance, so any of our temporally extended projects must be sustained over its temporal unfolding by momentary actions. We need both the capacity to organize these momentary steps in light of a synoptic overview of the extended activity as a whole and to sustain our motivation to continue to pursue the extended activity. Hence, the distinctive mode in which we (...) act over time is that of ’planning agency,’ which requires a form of temporal identification that goes beyond mere psychological continuity. I then discuss the differences in internal structure between merely continuous and integrated activities, and between telic and atelic ones. I provide a taxonomy of the different kinds of temporal goods and values and how these structures might bear on the risk of crisis of meaning in our temporal existence. I then touch briefly on the issue of how our mortality might make a difference to the structure of what we find valuable and how it relates to the temporal features of our agency. In the closing section, I discuss the effects of the moving temporal location of the agent (with her local executive powers) relative to her extended pursuits, including the asymmetries generated by the distinction between past and future stages of the activity and the moving horizon of what the agent can anticipate and (indirectly) control.

In this contribution I will retrace the main stages of my research on the objectification problem in quantum mechanics by highlighting some personal memories of my supervisor, the theoretical physicist Giovanni Morchio. The central aim of my MSc thesis was to ask whether the hypothesis of objectification, which is currently added to the formalism, is not, at least in one case, deducible from it and in particular from the dynamics of the temporal evolution. The case study we were looking for (...) had to: 1) represent a situation similar to that in which a macroscopic system such as a measurement apparatus, following interaction with a system, assumes a well-defined state (which or for example represents the fact that the result of a measurement is a particular value), i.e becomes objective 2) represent a fact in nature in which it is not clear whether its explanation can be derived from the formalism of quantum mechanics or whether a hypothesis of objectification is necessary for its explanation. Proving that such a fact can be deduced from the time evolution of quantum mechanics allowed us to conclude that there are cases in which the hypothesis of objectification is superfluous or, in other words, obtainable from the formalism.

In this paper, I discuss whether there are genuinely *diachronic* constraints of practical rationality, that is, pressures on combinations of practical attitudes over time, which are not reducible to mere synchronic rational pressures. Michael Bratman has recently argued that there is at least one such diachronic rational constraint that governs the stability of intentions over time. *Pace* Bratman, I argue that there are no genuinely diachronic constraints on intentions that meet the stringent desiderata set by him. But I show that (...) there are at least two synchronic rational constraints with distinctive and important, although only indirect, diachronic dimensions. Neither of them, however, supports the practical conservatism in the face of normative underdetermination that, according to Bratman, is part and parcel of the diachronic rationality of intention stability.

This chapter discusses the first part of Aristotle's Posterior Analytics A-33, 88b30-89a10. I claim that Aristotle is not concerned with an epistemological distinction between knowledge and belief in general. He is rather making a contrast between scientific knowledge (which is equivalent to explanation by the primarily appropriate cause) and some explanatory beliefs that falls short of capturing the primarily appropriate cause.

Paul Feyerabend, one of the most original and nonconformist epistemologists of the 20th century, is known for describing science as an essentially anarchic enterprise characterized by different, sometimes contradictory, methods, approaches and ways of reasoning. But it was through his reflections on art and myth that he developed an even more radical view: there are different forms of human thought, each characterized by a different rationality and reality, and science is only one of them. And in intellectual history there is (...) only change, but not progress. (shrink)

The combination of panpsychism and priority monism leads to priority cosmopsychism, the view that the consciousness of individual sentient creatures is derivative of an underlying cosmic consciousness. It has been suggested that contemporary priority cosmopsychism parallels central ideas in the Advaita Vedānta tradition. The paper offers a critical evaluation of this claim. It argues that the Advaitic account of consciousness cannot be characterized as an instance of priority cosmopsychism, points out the differences between the two views, and suggests an alternative (...) positioning of the Advaitic canon within the contemporary debate on monism and panpsychism.

I discuss the issue whether Aristotle's philosophy of science allows the use of mathematical premises or mathematical tools in general for explanaing phenomena in the natural sciences. I thereby discuss the concept of "metabasis eis allo genos" as it appears in Posterior Analytics I.7.

Many readers of Kant’s ethical writings take him to be primarily concerned with offering guidelines for action. At the least, they write about Kant as if this were the purpose of his ethical writings. For example, Christine Korsgaard, in her influential article Kant’s Analysis of Obligation: The Argument of Groundwork I, writes that, ‘‘the argument of Groundwork I is an attempt to give what I call a ‘motivational analysis’ of the concept of a right action, in order to discover what (...) that concept applies to, that is, which actions are right.’’ Similar comments are not hard to find in the secondary literature. This, however, is a fundamentally misguided way of reading Kant, since he repeatedly asserts that we do not need to do moral philosophy in order to discover which actions are right. We already know how to behave morally and do not need philosophers to tell us this. ‘‘Common human reason,’’ Kant argues, ‘‘knows very well how to distinguish in every case that comes up what is good and what is evil, what is in conformity to duty or contrary to duty.’’ Because people with pre-philosophical understanding know how to act morally, the purpose of moral philosophy cannot be to provide us with a set of rules for correct behavior. If we take Kant’s claims about common human reason seriously, then his aim in the Groundwork of the Metaphysics of Morals cannot be to discover which actions are right. (shrink)

There are two standard conceptions of the functioning of and rationale for the diachronic will, i.e., for an agent's capacity to settle on her future conduct in advance. According to the pragmatic-instrumentalist view, the diachronic will benefits us by increasing the long-term satisfaction of our rational preferences. According to the cognitive view, it benefits us by satisfying our standing desire for self-knowledge and self-understanding. Contrary to these views, I argue for a constitutive view of the diachronic will: the rationale for (...) it is that it makes possible to engage in activities with a radically novel temporal structure, activities that are not merely continuous over time, but temporally integrated and unified. These activities are essential to our form of life and to our existence as temporally unified agents. The instrumental and cognitive benefits, if any, are merely secondary to the ontological ones.

We present epistemic multilateral logic, a general logical framework for reasoning involving epistemic modality. Standard bilateral systems use propositional formulae marked with signs for assertion and rejection. Epistemic multilateral logic extends standard bilateral systems with a sign for the speech act of weak assertion (Incurvati and Schlöder 2019) and an operator for epistemic modality. We prove that epistemic multilateral logic is sound and complete with respect to the modal logic S5 modulo an appropriate translation. The logical framework developed provides the (...) basis for a novel, proof-theoretic approach to the study of epistemic modality. To demonstrate the fruitfulness of the approach, we show how the framework allows us to reconcile classical logic with the contradictoriness of so-called Yalcin sentences and to distinguish between various inference patterns on the basis of the epistemic properties they preserve.

Experiences like pains, pleasures, and emotions have affective phenomenal character: they feel pleasant or unpleasant. Imperativism proposes to explain affective phenomenal character by appeal to imperative content, a kind of intentional content that directs rather than describes. We argue that imperativism is on the right track, but has been developed in the wrong way. There are two varieties of imperativism on the market: first-order and higher-order. We show that neither is successful, and offer in their place a new theory: reflexive (...) imperativism. Our proposal is that an experience P feels pleasant in virtue of being constituted by a Command with reflexive imperative content, while an experience U feels unpleasant in virtue of being constituted by a Command with reflexive imperative content : More of P!Less of U! If you need a slogan: experiences have affective phenomenal character in virtue of commanding us Get more of me! Get less of me! (shrink)

ABSTRACTLinguistic evidence supports the claim that certain, weak rejections are less specific than assertions. On the basis of this evidence, it has been argued that rejected sentences cannot be premisses and conclusions in inferences. We give examples of inferences with weakly rejected sentences as premisses and conclusions. We then propose a logic of weak rejection which accounts for the relevant phenomena and is motivated by principles of coherence in dialogue. We give a semantics for which this logic is sound and (...) complete, show that it axiomatizes the modal logic KD45 and prove that it still derives classical logic on its asserted fragment. Finally, we defend previous logics of strong rejection as being about the linguistically preferred interpretations of weak rejections. (shrink)

According to the perceptual view of language comprehension, listeners typically recover high-level linguistic properties such as utterance meaning without inferential work. The perceptual view is subject to the Objection from Context: since utterance meaning is massively context-sensitive, and context-sensitivity requires cognitive inference, the perceptual view is false. In recent work, Berit Brogaard provides a challenging reply to this objection. She argues that in language comprehension context-sensitivity is typically exercised not through inferences, but rather through top-down perceptual modulations or perceptual learning. (...) This paper provides a complete formulation of the Objection from Context and evaluates Brogaards reply to it. Drawing on conceptual considerations and empirical examples, we argue that the exercise of context-sensitivity in language comprehension does, in fact, typically involve inference. (shrink)

In this chapter, I shall consider a number of connections between various ideas of the theory of styles of reasoning and the issue of the contingency and inevitability of science. By ‘contingency issue’ it is meant the question as to whether the history of a particular branch of our science could have taken a different route and provided results incompatible with those of our actual science. Apart from Hacking’s recent comments, the discussions on the contingency issue have not involved the (...) notion of style of reasoning. I will fill this gap in the literature by drawing some important implications for the issue of contingency from the theory of styles of reasoning that I have developed so far. I shall address four fundamental questions. First of all, in the next section I shall discuss to which extent the emergence of styles of reasoning at a certain point of history is a contingent circumstance. In the following section I shall ask whether the endurance of styles of reasoning was inevitable by tackling the connected question as to why the styles are long lasting. Afterwards, I shall focus on the growth of knowledge by dealing with questions such as: if a certain style of reasoning continues to be employed and if Q is a ‘live question’, is science bound to converge on a single answer to Q? Finally, on the basis of my previous reflections I shall look into the question of the convergence of science in the long run. The answers to these questions will rely on some basic assumptions of the theory of style of reasoning and imply a picture of the evolution of sciences in which both contingency and inevitability play a key role.

In this paper we argue that Michael Huemer’s phenomenal conservatism—the internalist view according to which our beliefs are prima facie justified if based on how things seems or appears to us to be—doesn’t fall afoul of Michael Bergmann’s dilemma for epistemological internalism. We start by showing that the thought experiment that Bergmann adduces to conclude that is vulnerable to his dilemma misses its target. After that, we distinguish between two ways in which a mental state can contribute to the justification (...) of a belief: the direct way and the indirect way. We identify a straightforward reason for claiming that the justification contributed indirectly is subject to Bergmann’s dilemma. Then we show that the same reason doesn’t extend to the claim that the justification contributed directly is subject to Bergmann’s dilemma. As is the view that seemings or appearances contribute justification directly, we infer that Bergmann’s contention that his dilemma applies to is unmotivated. In the final part, we suggest that our line of response to Bergmann can be used to shield other types of internalist justification from Bergmann’s objection. We also propose that seeming-grounded justification can be combined with justification of one of these types to form the basis of a promising version of internalist foundationalism. (shrink)

I discuss in this paper the six requirements Aristotle advances at Posterior Analytics A-2, 71b20-33, for the premisses of a scientific demonstration. I argue that the six requirements give no support for an intepretation in terms of “axiomatization”. Quite on the contrary, the six requirements can be consistently understood in a very different picture, according to which the most basic feature of a scientific demonstration is to explain a given proposition by its appropriate cause.

In this paper we focus on transmission and failure of transmission of warrant. We identify three individually necessary and jointly sufficient conditions for transmission of warrant, and we show that their satisfaction grounds a number of interesting epistemic phenomena that have not been sufficiently appreciated in the literature. We then scrutinise Wright’s analysis of transmission failure and improve on extant readings of it. Nonetheless, we present a Bayesian counterexample that shows that Wright’s analysis is partially incoherent with our analysis of (...) warrant transmission and prima facie defective. We conclude exploring three alternative lines of reply: developing a more satisfactory account of transmission failure, which we outline; dismissing the Bayesian counterexample by rejecting some of its assumptions; reinterpreting Wright’s analysis to make it immune to the counterexample.

We discuss a well-known puzzle about the lexicalization of logical operators in natural language, in particular connectives and quantifiers. Of the many logically possible operators, only few appear in the lexicon of natural languages: the connectives in English, for example, are conjunction _and_, disjunction _or_, and negated disjunction _nor_; the lexical quantifiers are _all, some_ and _no_. The logically possible nand (negated conjunction) and Nall (negated universal) are not expressed by lexical entries in English, nor in any natural language. Moreover, (...) the lexicalized operators are all upward or downward monotone, an observation known as the Monotonicity Universal. We propose a logical explanation of lexical gaps and of the Monotonicity Universal, based on the dynamic behaviour of connectives and quantifiers. We define update potentials for logical operators as procedures to modify the context, under the assumption that an update by \( \phi \) depends on the logical form of \( \phi \) and on the speech act performed: assertion or rejection. We conjecture that the adequacy of update potentials determines the limits of lexicalizability for logical operators in natural language. Finally, we show that on this framework the Monotonicity Universal follows from the logical properties of the updates that correspond to each operator. (shrink)

In this paper, we develop an impure somatic theory of emotion, according to which emotions are constituted by the integration of bodily perceptions with representations of external objects, events, or states of affairs. We put forward our theory by contrasting it with Prinz's pure somatic theory, according to which emotions are entirely constituted by bodily perceptions. After illustrating Prinz's theory and discussing the evidence in its favor, we show that it is beset by serious problems—i.e., it gets the neural correlates (...) of emotion wrong, it isn't able to distinguish emotions from bodily perceptions that aren't emotions, it cannot account for emotions being directed towards particular objects, and it mischaracterizes emotion phenomenology. We argue that our theory accounts for the empirical evidence considered by Prinz and solves the problems faced by his theory. In particular, we maintain that our theory gives a unified and principled account of the relation between emotions and bodily perceptions, the intentionality of emotions, and emotion phenomenology.

A pressing and difficult practical problem concerns the general issue of the right social response to offenders classified as having antisocial personality disorder. This paper approaches this general problem by focusing, from a philosophical perspective, on the still relevant but more approachable question whether psychopathic offenders are morally responsible. In particular, I investigate whether psychopaths possess moral understanding. A plausible way to approach the last question requires a satisfactory philosophical interpretation of the empirical evidence that appears to show that psychopaths (...) fail to draw the distinction between conventional and moral norms. Specifically, I will consider a recent philosophical debate polarized between supporters of rationalist and sentimentalist accounts of moral understanding. These opponents have discussed whether the case of psychopathy offers empirical support for their account and undermine the rival view. I will argue that the available empirical data leave the outcome of this discussion indeterminate. However, this implies that both these principal theories of moral understanding, if independently motivated, would imply that psychopaths have certain deficits that might affect their moral understanding and, consequently, their moral responsibility.

We present an inferentialist account of the epistemic modal operator might. Our starting point is the bilateralist programme. A bilateralist explains the operator not in terms of the speech act of rejection ; we explain the operator might in terms of weak assertion, a speech act whose existence we argue for on the basis of linguistic evidence. We show that our account of might provides a solution to certain well-known puzzles about the semantics of modal vocabulary whilst retaining classical logic. (...) This demonstrates that an inferentialist approach to meaning can be successfully extended beyond the core logical constants. (shrink)

Pictures are created objects that have the function of generating a perceptual experience. In this sense, they are “experiential artifacts” (Terrone forthcoming). The experience elicited by pictures – usually visual (but for non-visual pictorial experience see e.g. Lopes 1997) – is a composite perceptual experience, in which the “perception” of the depicted scene (which is not in front of us) is generated by and experienced along the perception of the marked surface (the object that is actually in front of us). (...) This experience is usually called a “pictorial experience”. A philosophical analysis of such an experience amounts to answering the following questions: How should we describe the phenomenology of pictorial experience? What is it like to experience pictures? How should the “perception” of the depicted scene be characterized? Is it really a form of perception? How does it relate to the perception of the marked surface? (shrink)

According to Jim Pryor’s dogmatism, when you have an experience with content p, you often have prima facie justification for believing p that doesn’t rest on your independent justification for believing any proposition. Although dogmatism has an intuitive appeal and seems to have an antisceptical bite, it has been targeted by various objections. This paper principally aims to answer the objections by Roger White according to which dogmatism is inconsistent with the Bayesian account of how evidence affects our rational credences. (...) If this were true, the rational acceptability of dogmatism would be seriously questionable. I respond that these objections don’t get off the ground because they assume that our experiences and our introspective beliefs that we have experiences have the same evidential force, whereas the dogmatist is uncommitted to this assumption. I also consider the question whether dogmatism has an antisceptical bite. I suggest that the answer turns on whether or not the Bayesian can determine the priors of hypotheses and conjectures on the grounds of their extra-empirical virtues. If the Bayesian can do so, the thesis that dogmatism has an antisceptical bite is probably false. (shrink)

In my paper, I shall provide a reading of Diogenes of Apollonia such that his understanding of the metaphysics of differentiation and of individual ensoulment may constitute an ingenious answer to the problems of his time. To this extent, I will argue that Diogenes' worldview solves the difficulties of Anaxagoras' metaphysics and successfully integrates mentality in a causally closed conception of nature. Finally, I will suggest that a Diogenes-inspired approach might be relevant to treat some pressing concerns in the contemporary (...) philosophy of mind – thus demonstrating how his production might offer some interesting solutions for the problems of our time too.

This is an introductory handbook for some of the main themes around the notion of predication in Aristotle. It does not aim at being exhaustive, but only sketches some important lines about the subject; it contains an introductory essay, besides the translation (into Portuguese) and commentary of basic texts (such as Posterior Analytics I-22, Categories 1-5, Interpretation 1-6 etc.).

There are three ways to control our future conduct: by causing it, by manipulating our future selves, or by taking future-directed decisions. I show that the standard accounts of future-directed decisions fail to do justice to their distinctive contribution in intentional diachronic agency. The standard accounts can be divided in two categories: First, those that conflate the operation of decisions with that of devices for either physical constraint or manipulative self-management. Second, accounts that, although they acknowledge the non-manipulative nature of (...) decisions, offer too restrictive a view of source of their effectiveness over time. I argue that a comprehensive view of decisions must acknowledge that there is a variety of ways in which they can be effective, which range from the exercise of rational authority to the reliance on sub-agential psychological propensities. What keeps all of these mechanisms together as possible explanations of the role of decisions in supporting diachronic intentional agency is that these mechanisms operate under a common regulative ideal of diachronic agency: the agent’s reliance on the continuous sense of the stability of the choiceworthiness of the action, regardless of her prior decision to perform it. In light of this regulative ideal, the contribution of effective decisions to diachronic agency is thus in principle dispensable although usually necessary for limited beings like us. (shrink)

O problema deste paper constitui-se a partir da seguinte pergunta: seria Platão um plagiador dos pitagóricos? A suspeita nasce de uma tradição já antiga pela qual Platão é acusado de ter plagiado uma suposta obra atualmente perdida de Filolau de Crotona. Tomou-se, então, como objeto de análise, a obra Timeu, a fim de verificar a existência de trechos que poderiam sugerir um plágio por parte de Platão. Para tanto, realizou-se um levantamento das principais teorias “pitagóricas” identificáveis no Timeu, a partir (...) de uma revisão da história da crítica. Concluiu-se que, inegavelmente, há referência implícita ao pitagorismo na obra, a qual, entretanto, não configura propriamente um plágio, mas, sim, pode ser melhor considerada como uma influência pitagórica. Efetivamente, Platão acaba por transpor diversas teorias “pitagóricas” – bem como de outros filósofos pré-socráticos – para seus próprios interesses filosóficos. (shrink)

We develop a novel solution to the negation version of the Frege-Geach problem by taking up recent insights from the bilateral programme in logic. Bilateralists derive the meaning of negation from a primitive *B-type* inconsistency involving the attitudes of assent and dissent. Some may demand an explanation of this inconsistency in simpler terms, but we argue that bilateralism’s assumptions are no less explanatory than those of *A-type* semantics that only require a single primitive attitude, but must stipulate inconsistency elsewhere. Based (...) on these insights, we develop a version of B-type expressivism called *inferential expressivism*. This is a novel semantic framework that characterises meanings by inferential roles that define which *attitudes* one can *infer* from the use of terms. We apply this framework to normative vocabulary, thereby solving the Frege-Geach problem generally and comprehensively. Our account moreover includes a semantics for epistemic modals, thereby also explaining normative terms under epistemic modals. (shrink)

According to some currents of modern historiography, Galilei's propensity for circular motion would have led him to consider this and not rectilinear motion as “natural motion”; therefore the principle of inertia could not be fully attributed to Galileo, which he would never have formulated. The question of the authorship of the principle of inertia certainly weighs on both nationalistic elements and returns of antigaleleism, while the question of its not explicit formulation as a principle is due to ignorance of the (...) type of organization that Galileo intended to give to the exposition of his physics. The author, after having hinted at possible prodromes of the principle of inertia and having reported the adverse opinions of illustrious historians of science (A. Koyré, I. B. Cohen, P. M. Duhem, P. Rossi, G. Holton), through a careful analysis of the Galilean writings, conducted on the digital versions with the help of text analysis programs, firmly reaffirms Galileo's authorship of the principle of inertia and the consequent principle of classical relativity.

This book discusses Aristotle’s notions of essence and substance as they are developed in Metaphysics ZH. I examine Aristotle's argument at length and defends an unorthodox interpretation according to which his motivation is to provide an answer against a conflation between criteria for existential priority (delivering substances as primary beings) and criteria for explanatory priority (delivering essences as primary principles).

Plant ethics is a field of philosophy that discusses the moral value of plants, and individual responsibilities toward them. As anthropogenic climate change is likely to have devastating effects on plants, a plant ethics analysis of climate change is crucial to fully understand the extent of people’s responsibilities toward plants. However, surprisingly little has been written on this topic. This chapter aims to provide an overview of the main positions in plant ethics as well as an initial exploration of the (...) following three salient questions concerning plant ethics and climate change. First, how stringent are people’s responsibilities to preserve plants? Second, do people have responsibilities to plant trees? Third, do people have responsibilities to help plant migration? Plant ethics theories struggle to different extent with each of these questions. On all theories, people have great responsibilities to preserve, if not individual plants, at least large forests, and on most theories people have some responsibility to help plant migration. On whether there are responsibilities to plant trees, different plant ethics theories deliver widely different results, from there being no responsibility to plant any tree to there being responsibility to plant as many trees as possible. All three questions are venues for future research in plant ethics. (shrink)

Paul Horwich (1990) once suggested restricting the T-Schema to the maximally consistent set of its instances. But Vann McGee (1992) proved that there are multiple incompatible such sets, none of which, given minimal assumptions, is recursively axiomatizable. The analogous view for set theory---that Naïve Comprehension should be restricted according to consistency maxims---has recently been defended by Laurence Goldstein (2006; 2013). It can be traced back to W.V.O. Quine(1951), who held that Naïve Comprehension embodies the only really intuitive conception of set (...) and should be restricted as little as possible. The view might even have been held by Ernst Zermelo (1908), who,according to Penelope Maddy (1988), subscribed to a ‘one step back from disaster’ rule of thumb: if a natural principle leads to contra-diction, the principle should be weakened just enough to block the contradiction. We prove a generalization of McGee’s Theorem, anduse it to show that the situation for set theory is the same as that for truth: there are multiple incompatible sets of instances of Naïve Comprehension, none of which, given minimal assumptions, is recursively axiomatizable. This shows that the view adumbrated by Goldstein, Quine and perhaps Zermelo is untenable. (shrink)

In this paper, I argue against the popular philosophical thesis---aka the ‘own action condition’---that an agent can only intend one’s own actions. I argue that the own action condition does not hold for any executive attitude, intentions included. The proper object of intentions is propositional rather than agential (‘I intend that so-and-so be the case’ rather than ‘I intend to do such-and-such’). I show that, although there are some essential de se components in intending, they do not restrict the content (...) of intentions to one’s own actions. I then discuss the special way in which one’s own actions can figure in the content of one’s intentions, which shows that the distinction between intending and acting is less stark than it appears at first. This is a conclusion that many defenders of the own action condition might find appealing but which, I argue, is better supported by rejecting the own action condition. (shrink)

As systems based on opaque Artificial Intelligence (AI) continue to flourish in diverse real-world applications, understanding these black box models has become paramount. In response, Explainable AI (XAI) has emerged as a field of research with practical and ethical benefits across various domains. This paper not only highlights the advancements in XAI and its application in real-world scenarios but also addresses the ongoing challenges within XAI, emphasizing the need for broader perspectives and collaborative efforts. We bring together experts from diverse (...) fields to identify open problems, striving to synchronize research agendas and accelerate XAI in practical applications. By fostering collaborative discussion and interdisciplinary cooperation, we aim to propel XAI forward, contributing to its continued success. Our goal is to put forward a comprehensive proposal for advancing XAI. To achieve this goal, we present a manifesto of 27 open problems categorized into nine categories. These challenges encapsulate the complexities and nuances of XAI and offer a road map for future research. For each problem, we provide promising research directions in the hope of harnessing the collective intelligence of interested stakeholders. (shrink)

ABSTRACT (ITA) Un’idea emerge, si sviluppa, guadagna consenso, muta, talvolta scompare per poi risorgere. Questo è anche stato il destino dell’idea di evoluzione, il cui lungo cammino viene ricostruito in questo saggio, dai Greci fino ai nostri giorni. A partire dal diciassettesimo secolo questa nozione assume sempre più rilevanza nello studio della natura. In ciascun pensatore l’idea di un’evoluzione delle specie viventi è stata accompagnata da una teoria volta a spiegare le cause e il meccanismo del mutamento. Questo saggio racconta (...) non soltanto la genesi e lo sviluppo dell’idea tout court che la natura in qualche modo si trasformi, ma anche la storia delle teorie che, assumendo come reale questa trasformazione, ne postulano una spiegazione. Particolare attenzione viene data ad alcuni aspetti spesso trascurati che hanno reso possibile il concetto di evoluzione del mondo vivente come la conosciamo adesso, di cui se ne mostra la rilevanza, già a partire dal pensiero greco. -/- ABSTRACT (ENG) An idea emerges, develops, gains consensus, evolves, sometimes disappears and then rises again. This was also the fate of the idea of evolution, whose long journey is reconstructed in this essay, from the Greeks to the present day. Since the seventeenth century, this idea has become more and more relevant in the study of nature. In each thinker the idea of an evolution of living species has been accompanied by a theory aimed at explaining the causes and the mechanism of change. This essay tells not only the genesis and development of the idea that nature somehow transforms itself, but also the history of the theories which, assuming this transformation as real, postulate an explanation. Particular emphasis is given to some often overlooked aspects that made possible the concept of evolution of the living world as we know it now, whose full relevance is shown, starting from Greek thought. Keywords: evolution, natural selection, Charles Darwin, history of ideas, history of science. (shrink)

In this chapter I draw the conclusions of my investigation into phenomenal conservatism. I argue that phenomenal conservatism isn’t actually plagued by serious problems attributed to it by its opponents, but that it neither possesses all the epistemic merits that its advocates think it has. I suggest that phenomenal conservatism could provide a more satisfactory account of everyday epistemic practices and a more robust response to the sceptic if it were integrated with a theory of inferential justification. I also identify (...) questions and issues relevant to the assessment of phenomenal conservatism to be investigated in further research. (shrink)

Norm theory (Kahneman & Miller, 1986) described a tendency for people to associate stronger regret with a negative outcome when it is a result of an exception (abnormal behavior) compared to when it is a result of routine (normal behavior). In two pre-registered studies, we conducted a replication and extension of three classic experiments on past behavior exception/routine contrasts (N = 684). We successfully replicated Kahneman and Miller’s (1986) experiments with the classic hitchhiker-scenario (Part 1) and car accident-scenario (Part 2). (...) In both cases, participants examined negative outcomes and tended to indicate a protagonist who deviated from own past behavior as more regretful than another who followed routine. Pre-registered extensions also showed effects for ratings of social norms, negative affect, and perceived luck. We did not find support for the Miller and McFarland (1986) experiment robbery scenario (Part 3) using a compensation measure, in that compensation to a victim of a robbery was not significantly different comparing exceptional and routine circumstances. However, a pre-registered extension showed that robbery under exceptional circumstances was regretted more than robbery under routine circumstances. We discuss implications for current and future research. (shrink)

One type of argument to sceptical paradox proceeds by making a case that a certain kind of metaphysically “heavyweight or “cornerstone” proposition is beyond all possible evidence and hence may not be known or justifiably believed. Crispin Wright has argued that we can concede that our acceptance of these propositions is evidentially risky and still remain rationally entitled to those of our ordinary knowledge claims that are seemingly threatened by that concession. A problem for Wright’s proposal is the so-called Leaching (...) worry: if we are merely rationally entitled to accept the cornerstones without evidence, how can we achieve evidence-based knowledge of the multitude of quotidian propositions that we think we know, which require the cornerstones to be true? This paper presents a rigorous, novel explication of this worry within a Bayesian framework, and offers the Entitlement theorist two distinct responses. (shrink)

Translation of Aristotle's Posterior Analytics I into Portuguese, with a few notes, experimental glossary and introduction. The translation, which was made at 2003/4, was preliminary and its publication was intended to provide a didactic tool for courses as well as a provisional resource in research seminars. It needs some revision. I am currently working (slowly...) on the revision of the translation and a new revised one will surely appear at some point.

Coherentism in epistemology has long suffered from lack of formal and quantitative explication of the notion of coherence. One might hope that probabilistic accounts of coherence such as those proposed by Lewis, Shogenji, Olsson, Fitelson, and Bovens and Hartmann will finally help solve this problem. This paper shows, however, that those accounts have a serious common problem: the problem of belief individuation. The coherence degree that each of the accounts assigns to an information set (or the verdict it gives as (...) to whether the set is coherent tout court) depends on how beliefs (or propositions) that represent the set are individuated. Indeed, logically equivalent belief sets that represent the same information set can be given drastically different degrees of coherence. This feature clashes with our natural and reasonable expectation that the coherence degree of a belief set does not change unless the believer adds essentially new information to the set or drops old information from it; or, to put it simply, that the believer cannot raise or lower the degree of coherence by purely logical reasoning. None of the accounts in question can adequately deal with coherence once logical inferences get into the picture. Toward the end of the paper, another notion of coherence that takes into account not only the contents but also the origins (or sources) of the relevant beliefs is considered. It is argued that this notion of coherence is of dubious significance, and that it does not help solve the problem of belief individuation. (shrink)

Translation of Aristotle's Metaphysics IV and VI, with notes. The translation is preliminary and intended as a provisional teaching tool to be also used in seminars and discussions with peers in order to reach a more elaborated version.

In this paper, I will discuss the various ways in which intentions can be said to be conditional, with particular attention to the internal conditions on the intentions’ content. I will first consider what it takes to carry out a conditional intention. I will then discuss how the distinctive norms of intention apply to conditional intentions and whether conditional intentions are a weaker sort of commitments than the unconditional ones. This discussion will lead to the idea of what I call (...) the ‘deep structure’ of intentions. Roughly, this is the idea that the conditional nature of our intentions is only partially made explicit in the expressions we use to communicate our intentions and in the explicit form of our thinking about and reasoning with them. Most conditions that qualify our intentions are part of a deep functional structure that can be evinced by observing the actual psychological functioning of intentions and by considering the rational requirements that they engage. I will argue that the deep structure of intentions is characteristically conditional. Genuinely unconditional intentions are only limiting instances of conditional intentions and their contribution to agency can only be understood in light of this fact. I will conclude by showing that the characteristic conditional structure of intentions is intimately related to distinctive features of human agency, especially to its unity over time. (shrink)

A subject S's belief that Q is well-grounded if and only if it is based on a reason of S that gives S propositional justification for Q. Depending on the nature of S's reason, the process whereby S bases her belief that Q on it can vary. If S's reason is non-doxastic––like an experience that Q or a testimony that Q––S will need to form the belief that Q as a spontaneous and immediate response to that reason. If S's reason (...) is doxastic––like a belief that P––S will need to infer her belief that Q from it. The distinction between these two ways in which S's beliefs can be based on S's reasons is widely presupposed in current epistemology but––we argue in this paper––is not exhaustive. We give examples of quite ordinary situations in which a well-grounded belief of S appears to be based on S's reasons in neither of the ways described above. To accommodate these recalcitrant cases, we introduce the notion of enthymematic inference and defend the thesis that S can base a belief that Q on doxastic reasons P1, P2, …, Pn via inferring enthymematically Q from P1, P2, …, Pn.
