En este artículo se analizan una serie de ideas filosóficas y de perspectivas interpretativas que el cuyano Damián Hudson utilizó para construir su obra Recuerdos históricos sobre la provincia de Cuyo (1864-1874), la cual se inscribe en los inicios de la historiografía erudita argentina. Se explora su idea de progreso, concepto que Hudson identifica con la providencia, potencia histórica incremental que despliega un desarrollo universal que hace avanzar a la humanidad y la nación hacia el bienestar y (...) el desarrollo. Ese sentido de la historia encarnaría una verdad histórica que es menester develar por quienes estudian el pasado, pero no por vía de la neutralidad valorativa, sino posicionándose de una manera crítica y reflexionando filosóficamente sobre los procesos de desenvolvimiento histórico provincial y nacional. Se concluye con unas reflexiones sobre los cruces interpretativos entre la historia como proceso y la historia escrita como ejercicio intelectual, conceptos que tienden a combinarse en la época objeto de estudio.

The aim of this article is to study the notion of derivability and its semantic counterpart in the context of non-transitive and non-reflexive substructural logics. For this purpose we focus on the study cases of the logics _S__T_ and _T__S_. In this respect, we show that this notion doesn’t coincide, in general, with a nowadays broadly used semantic approach towards metainferential validity: the notion of local validity. Following this, and building on some previous work by Humberstone, we prove that in (...) these systems derivability can be characterized in terms of a notion we call absolute global validity. However, arriving at these results doesn’t lead us to disregard local validity. First, because we discuss the conditions under which local, and also global validity, can be expected to coincide with derivability. Secondly, because we show how taking into account certain families of valuations can be useful to describe derivability for different calculi used to present _S__T_ and _T__S_. (shrink)

Given a three-valued definition of validity, which choice of three-valued truth tables for the connectives can ensure that the resulting logic coincides exactly with classical logic? We give an answer to this question for the five monotonic consequence relations $st$, $ss$, $tt$, $ss\cap tt$, and $ts$, when the connectives are negation, conjunction, and disjunction. For $ts$ and $ss\cap tt$ the answer is trivial (no scheme works), and for $ss$ and $tt$ it is straightforward (they are the collapsible schemes, in which (...) the middle value acts like one of the classical values). For $st$, the schemes in question are the Boolean normal schemes that are either monotonic or collapsible. (shrink)

In this paper we discuss the extent to which conjunction and disjunction can be rightfully regarded as such, in the context of infectious logics. Infectious logics are peculiar many-valued logics whose underlying algebra has an absorbing or infectious element, which is assigned to a compound formula whenever it is assigned to one of its components. To discuss these matters, we review the philosophical motivations for infectious logics due to Bochvar, Halldén, Fitting, Ferguson and Beall, noticing that none of them discusses (...) our main question. This is why we finally turn to the analysis of the truth-conditions for conjunction and disjunction in infectious logics, employing the framework of plurivalent logics, as discussed by Priest. In doing so, we arrive at the interesting conclusion that —in the context of infectious logics— conjunction is conjunction, whereas disjunction is not disjunction. (shrink)

In this paper we explore the connections between ethics and decision theory. In particular, we consider the question of whether decision theory carries with it a bias towards consequentialist ethical theories. We argue that there are plausible versions of the other ethical theories that can be accommodated by “standard” decision theory, but there are also variations of these ethical theories that are less easily accommodated. So while “standard” decision theory is not exclusively consequentialist, it is not necessarily ethically neutral. Moreover, (...) even if our decision-theoretic models get the right answers vis-`a-vis morally correct action, the question remains as to whether the motivation for the non-consequentialist theories and the psychological processes of the agents who subscribe to those ethical theories are lost or poorly represented in the resulting models.

This paper provides a novel reconstruction of Kant’s argument for transcendental idealism in the Transcendental Aesthetic. This reconstruction relies on two main contentions: first, that Kant accepts the then-ubiquitous view that all cognition is either from grounds or consequences, a view he props up by drawing a distinction between logical and real grounds; second, that Kant, like most of his contemporaries, holds that our representations are the most immediate grounds of our cognition. By stressing these elements, the most threatening objection (...) to Kant’s argument can be avoided, namely, the claim that Kant ignores the possibility that our representations of space and time are subjective in origin, but objective as regards their applicability. My reconstruction shows that this so-called neglected alternative objection is based on a conceptual confusion about the nature of a priori cognition. (shrink)

In recent years, the value-freeness of science has come under extensive critique. Early objectors to the notion of value-free science can be found in Rudner and Churchman, later objections occur in Leach and Gaa, and more recent critics are Kitcher, Douglas, and Elliott. The goal of this paper is to examine and critique two arguments opposed to the notion of a value-free science. The first argument, the uncertainty argument, cites the endemic uncertainty of science and concludes that values are needed (...) to give direction to scientific investigation. The second, or moral argument, cites the fact that scientists have moral obligations just like everyone else, and.. (shrink)

This article is concerned with an exploration of a family of systems—called immune logics—that arise from certain dualizations of the well-known family of infectious logics. The distinctive feature of the semantic of infectious logics is the presence of a certain “infectious” semantic value, by which two different though equivalent things are meant. On the one hand, it is meant that these values are zero elements for all the operations in the underlying algebraic structure. On the other hand, it is meant (...) that these values behave in a value-in-value-out fashion for all the operations in the underlying algebraic structure. Thus, in a rather informal manner, we will refer to immune logics as those systems whose underlying semantics count with a certain “immune” semantic value behaving in a way that is somewhat dual to that of the infectious values. In a more formal manner, carrying out this dualization will prove to be not as straightforward as one could imagine, since the two characterizations of infectiousness discussed above lead to two different outcomes when one tries to conduct them. We explore these alternatives and provide technical results regarding them, and the various logical systems defined using such semantics. (shrink)

This article aims to dualize several results concerning various types (including possibly Cut-free and Identity-free systems) of canonical multiple-conclusion sequent calculi, i.e. Gentzen-style deduction systems for sequents, equipped with well-behaved forms of left and right introduction rules for logical expressions. In this opportunity, we focus on a different kind of calculi that we dub cocanonical, that is, Gentzen-style deduction systems for sequents, equipped with well-behaved forms of left and right elimination rules for logical expressions. These systems, simply put, have rules (...) that proceed from sequents featuring complex formulas to sequents featuring their component subformulas. Our main goals are to prove soundness and completeness results for the target systems’ consequence relations in terms of their characteristic 3- or 4-valued non-deterministic matrices. (shrink)

For a free filter F on $$\omega $$ ω, endow the space $$N_F=\omega \cup \{p_F\}$$ N F = ω ∪ { p F }, where $$p_F\not \in \omega $$ p F ∉ ω, with the topology in which every element of $$\omega $$ ω is isolated whereas all open neighborhoods of $$p_F$$ p F are of the form $$A\cup \{p_F\}$$ A ∪ { p F } for $$A\in F$$ A ∈ F. Spaces of the form $$N_F$$ N F constitute the (...) class of the simplest non-discrete Tychonoff spaces. The aim of this paper is to study them in the context of the celebrated Josefson–Nissenzweig theorem from Banach space theory. We prove, e.g., that, for a filter F, the space $$N_F$$ N F carries a sequence $$\langle \mu _n:n\in \omega \rangle $$ ⟨ μ n : n ∈ ω ⟩ of normalized finitely supported signed measures such that $$\mu _n(f)\rightarrow 0$$ μ n ( f ) → 0 for every bounded continuous real-valued function f on $$N_F$$ N F if and only if $$F^*\le _K{\mathcal {Z}}$$ F ∗ ≤ K Z, that is, the dual ideal $$F^*$$ F ∗ is Katětov below the asymptotic density ideal $${\mathcal {Z}}$$ Z. Consequently, we get that if $$F^*\le _K{\mathcal {Z}}$$ F ∗ ≤ K Z, then: (1) if X is a Tychonoff space and $$N_F$$ N F is homeomorphic to a subspace of X, then the space $$C_p^*(X)$$ C p ∗ ( X ) of bounded continuous real-valued functions on X contains a complemented copy of the space $$c_0$$ c 0 endowed with the pointwise topology, (2) if K is a compact Hausdorff space and $$N_F$$ N F is homeomorphic to a subspace of K, then the Banach space C(K) of continuous real-valued functions on K is not a Grothendieck space. The latter result generalizes the well-known fact stating that if a compact Hausdorff space K contains a non-trivial convergent sequence, then the space C(K) is not Grothendieck. (shrink)

In this article, I take on a classic objection to Kant’s arguments in the Antinomy of Pure Reason: that the arguments are question-begging, as they draw illicit inferences from claims about representation to claims about reality. While extant attempts to vindicate Kant try to show that he does not make such inferences, I attempt to vindicate Kant’s arguments in a different way: I show that, given Kant’s philosophical backdrop, the inferences in question are not illicit. This is because the transcendental (...) realists that Kant was arguing against have certain philosophical commitments about the nature of ground which, if true, warrant the inferences that Kant draws. This historical corrective not only allows us to better understand Kant’s own thinking in the Antinomies but it also has important upshots for our understanding of Kant’s transcendental idealism.

In attempting to debunk moral realism through an appeal to evolutionary facts, debunkers face a series of problems, which we label the problems of scope, corrosiveness, and post‐hoc justification. To overcome these problems, debunkers must assume certain metaphysical or epistemological positions, or otherwise pre‐establish them. In doing so, they must assume or pre‐establish the very conclusion they seek in advancing the argument. This means that such debunking arguments either beg the question against the moral realist or are undermined as standalone (...) metaethical arguments. (shrink)

ABSTRACT One of the core issues where interpreters of Kant disagree concerns his alleged Noumenalism—the claim that the objects of our experience, which are in space and time, are underpinned by entities that are not spatio-temporal and that non-spatio-temporally cause our representations of empirical objects. Although there is much textual evidence in favour of Noumenalism, non-Noumenalists have also gathered a significant number of philosophical and exegetical challenges to such a reading of Kant. I present a novel way of understanding the (...) Noumenalist view, which characterises the distinction between appearances and things in themselves as the distinction between referents and truthmakers. I show that, on this interpretation of Kant, the most pressing problems for the Noumenalist reading are primarily based on equivocations between features of reference and features of truthmaking.

Our aim is to provide a sequent calculus whose external consequence relation coincides with the three-valued paracomplete logic `of nonsense' introduced by Dmitry Bochvar and, independently, presented as the weak Kleene logic K3W by Stephen C. Kleene. The main features of this calculus are (i) that it is non-reflexive, i.e., Identity is not included as an explicit rule (although a restricted form of it with premises is derivable); (ii) that it includes rules where no variable-inclusion conditions are attached; and (iii) (...) that it is hybrid, insofar as it includes both left and right operational introduction as well as elimination rules.

Critical thinking is often nominated as a graduate attribute, a learning outcome, and is even offered as a discrete subject in schools and universities. Therefore, it is important to gain clarity about the fundamental goal or purpose of critical thinking education. What should instructors be aiming at when they seek to instil critical thinking in their students? In this paper, we argue that the aim of critical thinking is the achievement and maintenance of intellectual autonomy. In setting out our argument (...) for this conclusion, we investigate the three most plausible candidates for the goal of critical thinking practice. The first such candidate is successful inquiry: inquiry that succeeds in obtaining epistemic goods such as knowledge, true belief, or empirically adequate explanation. The second candidate is epistemically virtuous inquiry, i.e. inquiry that exhibits the full range of epistemic virtues, including the skills and capacities needed to support them. The third candidate is intellectual autonomy. We develop an account of intellectual autonomy as a form of self-respect attached to one’s epistemic and intellectual life and argue that only intellectual autonomy in this sense does full justice to the practice of critical thinking.

In this chapter, my aim is to present an account of Immanuel Kant’s transcendental idealism that centers his view of propositions as mental acts. As I intend to show, Kant’s strategy in the Critique of Pure Reason is only intelligible under the assumption that the fundamental bearers of truth are mental entities.

It is commonly thought that Jean Perrin argued for the reality of atoms in the early twentieth century by using what Wesley Salmon calls a “common cause” argument, also known as robustness reasoning. After citing some concerns with this interpretation of Perrin, I offer a different interpretation of Perrin’s work that more closely depicts the details of Perrin’s reasoning in his relevant published writings. I then offer a historical argument that supports this interpretation and discuss the philosophical merits of Perrin’s (...) style of reasoning as I have presented it. I close by showing how my interpretation is distinct from previous interpretations of Perrin’s work. (shrink)

© 2016 Elsevier LtdJumping spiders are famous for their visually driven behaviors [1]. Here, however, we present behavioral and neurophysiological evidence that these animals also perceive and respond to airborne acoustic stimuli, even when the distance between the animal and the sound source is relatively large and with stimulus amplitudes at the position of the spider of ∼65 dB sound pressure level. Behavioral experiments with the jumping spider Phidippus audax reveal that these animals respond to low-frequency sounds by freezing—a common (...) anti-predatory behavior characteristic of an acoustic startle response. Neurophysiological recordings from auditory-sensitive neural units in the brains of these jumping spiders showed responses to low-frequency tones —recordings that also represent the first record of acoustically responsive neural units in the jumping spider brain. Responses persisted even when the distances between spider and stimulus source exceeded 3 m and under anechoic conditions. Thus, these spiders appear able to detect airborne sound at distances in the acoustic far-field region, beyond the near-field range often thought to bound acoustic perception in arthropods that lack tympanic ears [2]. Furthermore, direct mechanical stimulation of hairs on the patella of the foreleg was sufficient to generate responses in neural units that also responded to airborne acoustic stimuli—evidence that these hairs likely play a role in the detection of acoustic cues. We suggest that these auditory responses enable the detection of predators and facilitate an acoustic startle response. Video. (shrink)

Coach observation studies conducted since the 1970s have sought to determine the quantity and quality of verbal feedback provided by coaches to their athletes. Relatively few studies, however, have sought to determine the knowledge and beliefs of coaches that underpin this provision of feedback. The purpose of the current study was to identify the beliefs and knowledge that elite team sport coaches hold about providing, receiving and evaluating feedback in their training and competition environments. Semi-structured interviews conducted with 8 coaches (...) were inductively analysed, revealing three broad themes: thinking and learning about feedback, providing feedback, and evaluating feedback. Findings revealed a detailed array of knowledge about feedback across a wide range of sub-topics. Coaches saw feedback as a tool to improve performance, build athlete confidence, help athletes to monitor progress, and as a tool to improve their own performance. Novel insights about evaluating an athlete’s reception of feedback, and tailoring feedback for individual athletes, were provided by coaches. The findings also highlight areas in which future coach education offerings can better support coaches to provide effective feedback. (shrink)

We provide a logical matrix semantics and a Gentzen-style sequent calculus for the first-degree entailments valid in W. T. Parry’s logic of Analytic Implication. We achieve the former by introducing a logical matrix closely related to that inducing paracomplete weak Kleene logic, and the latter by presenting a calculus where the initial sequents and the left and right rules for negation are subject to linguistic constraints.

Infectious logics are systems that have a truth-value that is assigned to a compound formula whenever it is assigned to one of its components. This paper studies four-valued infectious logics as the basis of transparent theories of truth. This take is motivated as a way to treat different pathological sentences differently, namely, by allowing some of them to be truth-value gluts and some others to be truth-value gaps and as a way to treat the semantic pathology suffered by at least (...) some of these sentences as infectious. This leads us to consider four distinct four-valued logics: one where truth-value gaps are infectious, but gluts are not; one where truth-value gluts are infectious, but gaps are not; and two logics where both gluts and gaps are infectious, in some sense. Additionally, we focus on the proof theory of these systems, by offering a discussion of two related topics. On the one hand, we prove some limitations regarding the possibility of providing standard Gentzen sequent calculi for these systems, by dualizing and extending some recent results for infectious logics. On the other hand, we provide sound and complete four-sided sequent calculi, arguing that the most important technical and philosophical features taken into account to usually prefer standard calculi are, indeed, enjoyed by the four-sided systems.

Prayer, a repeated practice of paying attention to one's inner mental world, is a core behavior across many faiths and traditions, understudied by cognitive scientists. Previous research suggests that humans pray because prayer changes the way they feel or how they think. This paper makes a novel argument: that prayer changes what they feel that they perceive. Those who pray, we find, are more likely to report sensory and perceptual experiences which they take to be evidence of a god or (...) spirit. Across three studies encompassing data from thousands of participants across five different cultures, we find that the amount of time spent daily in prayer is associated with the frequency of such events—and that prayer is associated with some of these experiences more strongly than others. Time in prayer has the strongest relationship with the frequency of everyday events (like dreams or strong emotion) that are experienced as not generated by the self but by a god or spirit. Prayer is also associated with more anomalous experiences like voices and a sense of presence, but prayer has no association with more dramatic events such as possession, out‐of‐body experiences, and sleep paralysis. Our results not only suggest interesting relationships between practice and experience in a religious domain, but hint at the power of practice to shape experience more broadly. (shrink)

One of the enduring contributions of Descartes to philosophy is Descartes’ response to the challenge of scepticism. In addressing the challenge of scepticism Descartes understood that scepticism was a philosophical challenge which needed to be answered by taking into account its inner logic. It is not surprising therefore that Descartes sought to demonstrate as a counter-point to scepticism that there is at least one truth we can know with certitude, namely, the truth of the self. By fulfilling the demand of (...) indubitability the emergence of the truth of the self, as it were, signals certain victory for Descartes in his fight against scepticism. Yet so far as we cannot say that the truth of the cogito is objective unless God guarantees its objectivity, it remains to be seen whether Descartes’ victory over scepticism is conclusive. Consequently, while the discovery of the cogito represents a key moment in Descartes’ effort to contain scepticism so far as it furnishes him with an indubitable foundation, his effort to reconstruct the edifice of knowledge ends in failure so far as it witnesses a resurgence of scepticism in respect of our knowledge of the external world. The argument of this paper is that Descartes’ appeal to God as the guarantor of the objective certainty of the truth of the cogito grossly undermines the overall success of Descartes’ response to the challenge of scepticism.

In his recent article, Nicolas Rasmussen (2001) is harshly critical of what he terms 'empirical philosophy of science', a philosophy that takes seriously the history of science in advancing philosophical pronouncements about science. He motivates his criticism by reflecting on recent history in microbiology involving the 'discovery' of a new bacterial organelle, the mesosome, during the 1950's and 1960's, and the subsequent retraction of this discovery by experimental microbiologists during the late 1970's and early 1980's. In particular, he argues that (...) there was a lack of constancy in the methods microbiologists used in approaching the issue of the existence of mesosomes, and that in fact a similar sort of 'methodological flux' pervades all experimental work. My goal here is to refute Rasmussen's doctrine of flux, and in turn to re-establish order in our understanding of the methods and strategies of experimenters. My strategy in achieving this goal is to re-visit the same crucial research articles in the history of the mesosome episode that Rasmussen (2001) visits; and what I find upon returning to this literature is not flux, as Rasmussen seems to find, but a constancy of method in experimental reasoning, a constancy codified by what I call 'reliable process reasoning'.

This essay outlines a hierarchical framework of Reality that allows for degrees of Reality. I use Reality (with a capital “R”) to designate reality in a primitive, metaphysical sense. Reality, grounding, and essence are the key elements of the framework presented here. I assume that Reality must have a fundamental level and all fundamental phenomena must be Real. Moreover, I postulate that everything non-fundamental is ultimately grounded in the fundamental Real. But what about the Reality of the non-fundamental? I argue (...) that it is possible for non-fundamental phenomena to be Real, Unreal, or Semi-Real. The framework developed here accommodates these possibilities and illuminates them using the notion of essence. I argue that the essential nature of a phenomenon determines its degree of Reality. The framework does not assume that Reality must have degrees but only that it may have degrees. Its theoretical attractiveness consists in its ability to accommodate many diverse intuitions about grounding, help us better understand and classify theories about grounding, and illuminate Reality and its possible degrees.

ABSTRACT In this article, the first author provides a summary and translation from the Latin of an important early medical lecture on vampires by Nils Retzius. The lecture was delivered in Sweden, at Lund University, in 1737, and was published almost immediately thereafter. This important text has been overlooked by modern scholars of vampires. This article will bring the lecture back into circulation in its first English translation. The second author then offers an analysis of the intellectual background to this (...) rational debunking of vampires. He demonstrates how Retzius’s attempt at a comprehensive rational explanation for vampires, typical of much Enlightenment thinking, nevertheless employs a fusion of Galenic medical thinking with more modern medical and psychosomatic notions of medicine, as well as certain Lutheran notions concerning the devil and the spirit world. His argument scotches the belief in the idea of sympathetic magic affecting the dreams of the living, while emphasising the psychosomatic effects of the imagination on the physical body. (shrink)

I define two metaphysical positions that anti-physicalists can take in response to Jonathan Schaffer’s ground functionalism. Ground functionalism is a version of physicalism where explanatory gaps are everywhere. If ground functionalism is true, arguments against physicalism based on the explanatory gap between the physical and experiential facts fail. In response, first, I argue that some anti-physicalists are already safe from Schaffer’s challenge. These anti-physicalists reject an underlying assumption of ground functionalism: the assumption that macrophysical entities are something over and above (...) the fundamental entities. I call their position “lightweight anti-physicalism.” Second, I go on to argue that even if anti-physicalists accept Schaffer’s underlying assumption, they can still argue that the consciousness explanatory gap is especially mysterious and thus requires a special explanation. I call the resulting position “heavyweight anti-physicalism.” In both cases, the consciousness explanatory gap is a good way to argue against physicalism. (shrink)

In this article we revisit a number of disputes regarding significance logics---i.e., inferential frameworks capable of handling meaningless, although grammatical, sentences---that took place in a series of articles most of which appeared in the Australasian Journal of Philosophy between 1966 and 1978. These debates concern (i) the way in which logical consequence ought to be approached in the context of a significance logic, and (ii) the way in which the logical vocabulary has to be modified (either by restricting some notions, (...) or by adding some vocabulary) to keep as much of Classical Logic as possible. Our aim is to show that the divisions arising from these disputes can be dissolved in the context of a novel and intuitive proposal that we put forward. (shrink)

In this paper, I present an interpretation of Kant’s view that reason’s hypostasis of the idea of a sum-total of reality is dogmatic and illegitimate. In the section on the ‘Transcendental Ideal’, the second section of the Ideal of Pure Reason chapter in the Critique of Pure Reason, Kant starts by describing reason’s procedure from the affirmation of the principle of thoroughgoing determination to the hypostasis in question. According to the interpretation I defend, the argument for hypostasis deployed in this (...) section constitutes an improvement upon an argument defended by the pre-critical Kant himself in his 1673 essay “The Only Possible Argument in Support of a Demonstration of the Existence of God”. By making reference to the concept of omnitudo realitatis, the argument in the ‘Transcendental Ideal’ section presents a much more radical and convincing interpretation of the thesis that ‘possibility presupposes actuality’. Second, I present transcendental idealism and its related distinction between objects of sense and objects in general as the main dissuasive argument of the critical philosopher against hypostasis. Finally, I consider an argument against hypostasis that is independent of transcendental idealism: the threat of set-theoretical paradoxes if we hypostatize the relevant idea, intended as the concept of an absolutely comprehensive totality.

Some recent researches in experimental philosophy have posed a problem for philosophers’ appeal to intuition (hereinafter referred to as PAI); the aim of this paper is to offer an answer to this challenge. The thesis against PAI implies that, given some experimental results, intuition does not seem to be a reliable epistemic source, and —more importantly— given the actual state of knowledge about its operation, we do not have sufficient resources to mitigate its errors and thus establish its reliability. That (...) is why PAI is hopeless. Throughout this paper I will defend my own conception of PAI, which I have called the Deliberative Conception, and consequently, I will defend intersubjective agreement as a means to mitigate PAI errors, offering empirical evidence from recent studies on the Argumentative Theory of Reason that favor the conception I defend here. Finally, I will reply to some objections that might arise against the Deliberative Conception, which will lead me to discuss some metaphilosophical issues that are significantly relevant for the future of the dispute about the appeal to intuition.

The Renaissance sceptic and medical doctor Francisco Sanchez has been rather unduly neglected in scholarly work on Renaissance scepticism. In this paper I discuss his scepticism against the background of the ancient distinction between Academic and Pyrrhonian scepticism. I argue that Sanchez was a Pyrrhonist rather than, as has been claimed in recent years, a mitigated Academic sceptic. In keeping with this I shall also try to show that Sanchez was crucially influenced by the ancient medical school of empiricism, a (...) school closely allied with Pyrrhonism. (shrink)

This article takes stock of the project of ecological democracy, a project that has been central to debates in Environmental Values since the late 1990s. Whilst we can identify quite distinct articulations of eco-democratic thinking emerging out of the fields of green political theory, postcolonial/feminist political ecology and science studies/radical geography, it is argued that these discussions have reached something of an impasse of late following the rise of climate scepticism, authoritarian populisms and technocratic eco-modernisms. Resurgent eco-authoritarian impulses and the (...) hankering for a ‘green leviathan’, a climate Lenin or a ‘dictatorship of the sustainment’ to resolve our climate crisis make it more important than ever to affirm the need for just, rapid and democratic post-carbon transitions. The article goes on to outline how emerging discussions in radical design studies focused on redirective practice in conjunction with a revived eco-socialist focus on labour-focused political ecologies might open up different possibilities for a materialist re-grounding of ecodemocratic discussions. It is suggested that a political ecology of design embedded in public institutions, the workplace and civil society could possibleyreground a more substantive vision of ecological democracy but also allow us to think about the forms of creative labour that could drive the just transition.

Paraconsistent logics are logical systems that reject the classical principle, usually dubbed Explosion, that a contradiction implies everything. However, the received view about paraconsistency focuses only the inferential version of Explosion, which is concerned with formulae, thereby overlooking other possible accounts. In this paper, we propose to focus, additionally, on a meta-inferential version of Explosion, i.e. which is concerned with inferences or sequents. In doing so, we will offer a new characterization of paraconsistency by means of which a logic is (...) paraconsistent if it invalidates either the inferential or the meta-inferential notion of Explosion. We show the non-triviality of this criterion by discussing a number of logics. On the one hand, logics which validate and invalidate both versions of Explosion, such as classical logic and Asenjo–Priest’s 3-valued logic LP. On the other hand, logics which validate one version of Explosion but not the other, such as the substructural logics TS and ST, introduced by Malinowski and Cobreros, Egré, Ripley and van Rooij, which are obtained via Malinowski’s and Frankowski’s q- and p-matrices, respectively.

In Kripke’s classic paper on truth it is argued that by adding a new semantic category different from truth and falsity it is possible to have a language with its own truth predicate. A substantial problem with this approach is that it lacks the expressive resources to characterize those sentences which fall under the new category. The main goal of this paper is to offer a refinement of Kripke’s approach in which this difficulty does not arise. We tackle this characterization (...) problem by letting certain sentences belong to more than one semantic category. We also consider the prospect of generalizing this framework to deal with languages containing vague predicates. (shrink)
