Kant’s most prominent formulation of the Categorical Imperative, known as the Formula of Universal Law (FUL), is generally thought to demand that one act only on maxims that one can will as universal laws without this generating a contradiction. Kant's view is standardly summarized as requiring the 'universalizability' of one's maxims and described in terms of the distinction between 'contradictions in conception' and 'contradictions in the will'. Focusing on the underappreciated significance of the simultaneity condition included in the FUL, (...) I argue, by contrast, that the principle is better read as requiring that one be able to will two things simultaneously without self-contradiction, namely, that a maxim be one's own and that it be a universal law. This amounts to a new interpretation of the FUL with significant interpretive and philosophical advantages. (shrink)

Coastal protection is crucial to human development since the ocean has many values associated with the economy, ecosystem, and culture. However, most ocean protecting efforts are currently ineffective due to the burdens of finance, lack of appropriate management, and international cooperation regimes. For aiding bottom-up initiatives for ocean protection support, this study employed the Mindsponge Theory to examine how the public’s perceived economic and cultural values influence their willingness to support actions to protect the ocean. Analyzing the European-Union-Horizon-2020-funded dataset of (...) 709 respondents from 42 countries, we discovered that perceived economic values have negative effects on the tendency of ocean protection supports (i.e., food, transportation, renewable energy, oil and gas, and recreation). In contrast, certain perceived cultural values can help increase the willingness to do so (i.e., mental well-being and sense of identity). However, the effects of perceived cultural values are only moderately reliable. These findings suggest that designing cultural information delivery campaigns can help promote coastal reserve supports, such as fundraisings and preserving the oceans from the community. (shrink)

In this analysis of one of the most difficult and neglected topics in Hegelian studies, Songsuk Susan Hahn tackles the status of contradiction in Hegel's ...

One of the most important difficulties facing Kant’s Formula of Universal Law (FUL) is its apparent inability to show that it is always impermissible to kill others for the sake of convenience. This difficulty has led current Kantian ethicists to de-emphasize the FUL or at least complement it with other Kantian principles when dealing with murder. The difficulty stems from the fact that the maxim of convenience killing fails to generate a ‘contradiction in conception’, producing only a ‘contradiction (...) in the will’ when subjected to the two-fold test associated with the FUL. This result is thought to imply that the FUL allows us sometimes to kill for the sake of convenience. In this essay, I argue that the very diagnosis of the problem rests on a mistake, and that if the maxim of convenience killing generates a contradiction in the will, then acting on it is never permissible.

The purpose of this essay is to shed some light on a certain type of sentence, which I call a borderline contradiction. A borderline contradiction is a sentence of the form F a ∧ ¬F a, for some vague predicate F and some borderline case a of F , or a sentence equivalent to such a sentence. For example, if Jackie is a borderline case of ‘rich’, then ‘Jackie is rich and Jackie isn’t rich’ is a borderline (...) class='Hi'>contradiction. Many theories of vague language have entailments about borderline contradictions; correctly describing the behavior of borderline contradictions is one of the many tasks facing anyone offering a theory of vague language. Here, I first briefly review claims made by various theorists about these borderline contradictions, attempting to draw out some predictions about the behavior of ordinary speakers. Second, I present an experiment intended to gather relevant data about the behavior of ordinary speakers. Finally, I discuss the experimental results in light of several different theories of vagueness, to see what explanations are available. My conclusions are necessarily tentative; I do not attempt to use the present experiment to demonstrate that any single theory is incontrovertibly true. Rather, I try to sketch the auxiliary hypotheses that would need to be conjoined to several extant theories of vague language to predict the present result, and offer some considerations regarding the plausibility of these various hypotheses. In the end, I conclude that two of the theories I consider are better-positioned to account for the observed data than are the others. But the field of logically-informed research on people’s actual responses to vague predicates is young; surely as more data come in we will learn a great deal more about which (if any) of these theories best accounts for the behavior of ordinary speakers.

Heraclitus uses paradoxical language to present the relationship between opposites in his worldview. This mode of expression has generated much controversy. Some take the paradoxes as evidence of a contradictory identity of opposites (Barnes), while others propose a dynamic union through transformation without identity that avoids the contradiction (Graham). By examining B88 and B62, I seek to identify the stronger and weaker points of such readings. The contradictory identity reading thwarts the transformation between opposites. The dynamic reading offers a (...) plausible alternative. However, it skips a characterization of how Heraclitus conceives of the transformation between opposites in physical terms. To fill this gap, I consider Heraclitus’ use of what I call the anti-cognate internal object in B62. I argue that ‘living the death and dying the life’ is a case of change as mixture, a popular conception among the early Presocratics. Upon closer examination, the anti-cognate internal object suggests that real contradictions belong to Heraclitus conception of change. The details reveal a philosophically compelling view. (shrink)

Is there a notion of contradiction—let us call it, for dramatic effect, “absolute”—making all contradictions, so understood, unacceptable also for dialetheists? It is argued in this paper that there is, and that spelling it out brings some theoretical benefits. First it gives us a foothold on undisputed ground in the methodologically difficult debate on dialetheism. Second, we can use it to express, without begging questions, the disagreement between dialetheists and their rivals on the nature of truth. Third, dialetheism has (...) an operator allowing it, against the opinion of many critics, to rule things out and manifest disagreement: for unlike other proposed exclusion-expressing-devices (for instance, the entailment of triviality), the operator used to formulate the notion of absolute contradiction appears to be immune both from crippling expressive limitations and from revenge paradoxes—pending a rigorous nontriviality proof for a formal dialetheic theory including it.

In this article, I reply to Jens Timmermann’s critical discussion of my essay “Contradiction and Kant’s Formula of Universal Law”. I first consider Timmermann’s reasons for rejecting my interpretation of the Formula of Universal Law. I argue that the self-contradiction relevant to determining a maxim’s moral status should not be sought in the imagined world in which the maxim is a universal law. I then discuss Timmermann’s suggestion that something like a volitional self-contradiction is found within the (...) will of the immoral agent. I deny this and clarify that the relevant contradiction is diagnosed counterfactually in moral reflection. Finally, I explain the differences between Timmermann’s account, Korsgaard’s Practical Contradiction interpretation, and my own Volitional Self-Contradiction interpretation. (shrink)

At the end of the first hypothesis, Parmenides gets Aristotle to agree that being [οὐσίας] must be in time; that is, that being must partake in at least one of the temporal modes: either to have been in the past, to be in the present, or it will be in the future (140e-142a). If this is true, then “the one does not partake in being” (141e7-8), meaning temporal being—to which Aristotle agrees, saying “Apparently not” (141e9). Parmenides then gets Aristotle to (...) agree that “Therefore, ‘the one’ in no way is” (141e9-10). This, however, contradicts the very first premise that begins Parmenides’ entire gymnastic exercise, “if one is” (137c4). The problem with the previous conclusion—that to be is to be in time—is that in professing his assent to it, Aristotle, in fact, gainsays it. He performatively contradicts the very thing he wants to assert. Aristotle answers Parmenides question, “Therefore could something partake of being in any way other than in one of those ways?” (141e7-8) with a two-word answer in Greek: “οὐκ ἔστιν [It’s not possible].” We can, therefore, ask of the very claim Aristotle is making—that it is impossible for something to be and not be in time—when in time does it hold true? At what time is it “not possible [οὐκ ἔστιν]” for something to not partake of temporal being? Is it not possible only in the present moment, in the past, or in the future? If Aristotle’s assertion is to have any force it must hold always. It has the same tenselessness as mathematical propositions, like ‘1+1=2.’ Forms, like mathematical entities, must necessarily have atemporal existence. Accordingly, in atemporally maintaining that anything that is must be in time, Aristotle undermines his own assertion. He performatively contradicts the very thing that he wants to affirm. (shrink)

A dialectical contradiction can be appropriately described within the framework of classical formal logic. It is in harmony with the law of noncontradiction. According to our definition, two theories make up a dialectical contradiction if each of them is consistent and their union is inconsistent. It can happen that each of these two theories has an intended model. Plenty of examples are to be found in the history of science.

In this paper, I offer a close reading of Wittgenstein's remarks on inconsistency, mostly as they appear in the Lectures on the Foundations of Mathematics. I focus especially on an objection to Wittgenstein's view given by Alan Turing, who attended the lectures, the so-called ‘falling bridges’-objection. Wittgenstein's position is that if contradictions arise in some practice of language, they are not necessarily fatal to that practice nor necessitate a revision of that practice. If we then assume that we have adopted (...) a paraconsistent logic, Wittgenstein's answer to Turing is that if we run into trouble building our bridge, it is either because we have made a calculation mistake or our calculus does not actually describe the phenomenon it is intended to model. The possibility of either kind of error is not particular to contradictions nor inconsistency, and thus contradictions do not have any special status as a thing to be avoided. (shrink)

The goals of this paper are two-fold: I wish to clarify the Aristotelian conception of the law of non-contradiction as a metaphysical rather than a semantic or logical principle, and to defend the truth of the principle in this sense. First I will explain what it in fact means that the law of non-contradiction is a metaphysical principle. The core idea is that the law of non-contradiction is a general principle derived from how things are in the (...) world. For example, there are certain constraints as to what kind of properties an object can have, and especially: some of these properties are mutually exclusive. Given this characterisation, I will advance to examine what kind of challenges the law of non-contradiction faces; the main opponent here is Graham Priest. I will consider these challenges and conclude that they do not threaten the truth of the law of non-contradiction understood as a metaphysical principle. (shrink)

The Law of Non-Contradiction holds that both sides of a contradiction cannot be true. Dialetheism is the view that there are contradictions both sides of which are true. Crucial to the dispute, then, is the central notion of contradiction. My first step here is to work toward clarification of that simple and central notion: Just what is a contradiction?

Wittgenstein's farcical clash with literary critic F. R. Leavis over the analysis of Empson's poem "Legal Fiction" is well known to devotees of Wittgenstein's life (Ludwig Wittgenstein: Personal Recollections (1981), edited by Rush Rhees, Oxford: Basil Blackwell, 80). Less well known is the value of studying Empson's artistic and intellectual achievement as part of the wider cultural background for the appreciation of Wittgenstein's views and influence, early and late. This talk sketches some diverting byways awaiting further exploration. A recurrent theme (...) is contradiction. (shrink)

It is widely believed, among philosophers of literature, that imagining contradictions is as easy as telling or reading a story with contradictory content. Italo Calvino’s The Nonexistent Knight, for instance, concerns a knight who performs many brave deeds, but who does not exist. Anything at all, they argue, can be true in a story, including contradictions and other impossibilia. While most will readily concede that we cannot objectually imagine contradictions, they nevertheless insist that we can propositionally imagine them, and regularly (...) do, simply by entertaining a text which prompts us to do so. I argue that this narrative does not bear scrutiny for two main reasons. First, because propositional imagining is beside the point, where truth in fiction is concerned; evaluating truth in fiction engages the cognitive architecture in ways that prohibit the mobilization of merely propositional imagination to that end. And second, because it is not obvious, given the strategies usually suggested, that we ever propositionally imagine contradictions in the first place—in fact, it seems we go out of our way to avoid directly imagining them.

Here, by introducing a version of “Unexpected hanging paradox” first we try to open a new way and a new explanation for paradoxes, similar to liar paradox. Also, we will show that we have a semantic situation which no syntactical logical system could support it. Finally, we propose a claim in Theory of Computation about the consistency of this Theory. One of the major claim is:Theory of Computation and Classical Logic leads us to a contradiction.

Tong Shijun holds a concept of dialectics which can also be found in Mao’s writings and in classical Chinese philosophy. Tong, however, is ambivalent in his attitude to dialectics in this sense, and for this reason he recommends Chinese philosophy to focus more on formal logic. My point will be that with another concept of dialectics Tong can have dialectics without giving up on logic and epistemology. This argument is given substance by an analysis of texts by Mao, Tong and (...) Hegel. (shrink)

In Metaphysics Γ, Aristotle argues against those who seem to accept contradictions. He distinguishes between the Sophists, who deny the principle of non-contradiction through arguments, and the Natural Philosophers, whose physical investigations lead to the acceptance of objective contradictions. Heraclitus’ name appears throughout the discussion. Usually, he is associated with the discussion against the Sophists. In this paper, I explore how the discussion with the Natural Philosophers may illuminate both the interpretation of Heraclitus by Aristotle and Heraclitus’ own worldview. (...) To refute the Natural Philosophers, Aristotle proposes a general reconstruction of their reasoning. Roughly, relying on sensory evidence (A1), they see that the same thing changes from one opposite to another (A2). Such a change appears to characterize a generation out of non-being, which a Natural Philosopher does not accept (A3). To solve the problem, despite their different worldviews, Natural Philosophers hint at a state in which opposites co-occur, characterizing an objective contradiction (C). Looking at the discussion in Metaphysics Γ and Heraclitus fragments, sections 1–3 show how assumptions A1, A2, and A3 easily apply to Heraclitus. The case of the conclusion is more challenging. In the case of the Pluralists, the co-existence of opposites characterizes a state in which there is no generation. Such a view does not fit Heraclitus’ mobilism. To argue that Aristotle’s argument is general enough to encompass dynamic views, I examine his problematization of accepting the change of change in Metaphysics K and Physics V. There, after re-stating several points that appear in Metaphysics Γ, Aristotle argues that accepting the becoming of another becoming leads to a state of contradiction in which the becoming is perishing. Heraclitus’ B8, cited in Nicomachean Ethics, gives evidence that, for Aristotle, Heraclitus puts a process at the origin of an opposite process. Moreover, after examining the expression ‘living the death/dying the life’ in B62, I argue that Heraclitus was aware that his worldview implied a dynamic objective contradiction. Finally, an analysis of elemental changes in B36 proves that accepting objective contradictions does not make Heraclitus’ worldview less attractive. (shrink)

This article debunks Bruno Latour’s seemingly pro-scientific and well-intentioned posture. I briefly summarize Latour’s constructivist, relativist, hybridist, and mystic philosophy, insisting on his radicalization in his last two books. I show that Latour’s conception is akin to “pseudo-profound bullshit”, inasmuch as he tries to hide his mysticism behind the invocation of scientific facts. I then concentrate on Latour’s politicization of climate science, showing that it is: self-contradictory from an epistemological point of view, since it presupposes scientifically established facts while at (...) the same time undermining their objectivity; counterproductive, and even dangerous, from the political point of view, since it recommends a full politicization of climate science and ignores its harmful effects. I conclude by advocating a distinction between science and politics, and by showing that Latour’s philosophy fosters our current post-truth predicament. (shrink)

This essay argues that we should find Crimmigration, which is the collapsing of immigration law with criminal law, morally problematic for three reasons. First, it denies those who are facing criminal penalties important constitutional protections. Second, it doubly punishes those who have already served their criminal sentence with an added punishment that should be considered cruel and unusual (i.e., indefinite imprisonment or exile). Third, when the tactics aimed at protecting and serving local communities get usurped by the federal government for (...) immigration enforcement purposes, they often undermine these original aims or get used in ways that conflict with the U.S. Constitution. These concerns should prompt us therefore either to reject the government’s plenary power over immigration or require the federal government to be more consistent about maintaining the separation between criminal law and immigration law.

Leibniz was a philosopher of principles: the principles of Contradiction, of Sufficient Reason, of Identity of Indiscernibles, of Plenitude, of the Best, and of Continuity are among the most famous Leibnizian principles. In this article I shall focus on the first three principles; I shall discuss various formulations of the principles (sect. 1), what it means for these theses to have the status of principles or axioms in Leibniz’s philosophy (sect. 2), the fundamental character of the Principles of (...) class='Hi'>Contradiction and Sufficient Reason (sect. 3), some attempts to demonstrate the Principles of Contradiction and Sufficient Reason (sect. 4), and one attempt to demonstrate the Principle of Identity of Indiscernibles (sect. 5).

We show how some model-theoretical devices (local reasoning, modes of presentation, an additional accessibility relation) can be combined in first-order modal logic to formalize the consequence relation that includes de dicto and de re contradictory beliefs. Instead of special ``sense objects'', appearances of objects in an agent's belief are introduced and presented as ordered pairs consisting of an object and an individual constant. A non-classical identity relation is applied. A relation S on the set of possible worlds is introduced, which (...) models possible distortions in an agent's picture of a (real) world. The application of such models in deontic logic is illustrated by a characteristic example. (shrink)

This paper focuses on Aristotle’s discussion of PNC in Metaphysics Gamma and argues that the argument operates at three different levels: ontological, doxastic, and semantic through the invocation of three philosophical personae: the first one can only state what is otherwise unprovable, the second one can only confirm that we should trust PNC, the third one denies PNC and must be silenced. Aristotle cannot prove what is beyond proof. This situation results in a fundamental ambiguity in the figure of the (...) philosopher. The Metaphysics is written from the standpoint of an investigative thinker who admits her puzzlement before a question that will forever remain open and imagines another philosopher who has achieved a god-like insight into the first principles of all things. The path from the first figure to the second one, however, remains an enigmatic leap. (shrink)

The following discourse is a brief yet appealing comparative analysis of two viewpoints on the same subject of Karma Yoga (detached 'witness–consciousness' through action) written separately by two stalwarts of Indian philosophy: Rabindranath Tagore (1915) and Swami Vivekananda (1896).

Special relativity has changed the fundamental view on space and time since Einstein introduced it in 1905. It substitutes four dimensional spacetime for the absolute space and time of Newtonian mechanics. It is believed that the validities of Lorentz invariants are fully confirmed empirically for the last one hundred years and therefore its status are canonical underlying all physical principles. However, spacetime metric is a geometric approach on nature when we interpret the natural phenomenon. A geometric flaw on this will (...) be exhibited and the alternative is suggested. The reasonable geometric model of space and time is a three dimensional space which is translating along the time direction. This model legitimately represents the true characteristic of nature.

In both Metaphysics Γ 4 and 5 Aristotle argues that Protagoras is committed to the view that all contradictions are true. Yet Aristotle’s arguments are not transparent, and later, in Γ 6, he provides Protagoras with a way to escape contradictions. In this paper I try to understand Aristotle’s arguments. After examining a number of possible solutions, I conclude that the best way of explaining them is to (a) recognize that Aristotle is discussing a number of Protagorean opponents, and (b) (...) import another of Protagoras’ views, namely the claim that there are always two logoi opposed to one another.

In his In Contradiction (1987), Priest levelled three powerful arguments against the received Russellian view of change and motion. He argued that his preferred paraconsistent theory of change, the Hegelian account, is immune from these objections. Here I argue that these three arguments are sound, but that the Hegelian account falls pray to them too. I conclude, however, that the Hegelian account is in a better position to tackle these challenges.

This chapter interprets G. E. M. Anscombe’s discussion in §31 of Intention of the relationship between expressions of intention and descriptions of matters of fact. For Anscombe, a statement like “I’m raising my arm” or “I’m going to get up at 7:00”, which expresses an intention by saying what is happening or is going to happen, is contradicted only by an opposing command or the expression of an opposing intention. I first challenge an interpretation of this passage as claiming that (...) the truth of statements like these is somehow independent of whether the action they describe is actually performed. Against this reading, my preferred interpretation highlights the fact that Anscombe is speaking here only of what contradicts expressions of intention, while her position is that statements like these describe the world in ways that will be contrary to, and so truth-functionally incompatible with, any opposing statements of fact.

This article challenges the prevailing interpretations of Hegel's account of the concept "contradiction" in the Science of Logic by arguing that it is concerned with the principle of Hegel's method rather than with the classical law of non-contradiction. I first consider Hegel's Doctrine of Essence in view of Kant's discussion of the concepts of reflection in the first Critique. On this basis, I examine Hegel's account of the logical principles based on the concepts "identity," "opposition," and "contradiction." (...) Finally, I point out how the principle Hegel derives from the concept of contradiction actually informs his own method. (shrink)

In this review I briefly analyse the main elements of each chapter of the book centred in the general areas of logic, epistemology, philosophy and history of science. Most of them are developed around a fine-grained investigation on the principle of non-contradiction and the concept of consistency, inquired mainly into the broad area of paraconsistent logics. The book itself is the result of a work that was initiated on the Studia Logica conference "Trends in Logic XVI: Consistency, Contradiction, (...)

Previously it was found that the Thing is both One Thing and another Thing at the same time. The Understanding rejects such a contradiction but Reason accepts what comes before it and allows the necessity in thought to proceed to its own conclusion. The attempt to maintain distinctions such as essential vs. unessential, singleness vs. universality, etc. may appeal to what is called ‘ordinary common sense,’ but it can now be seen that they are really only abstractions from the (...) actual truth that constitutes the entirety of perceptual consciousness. Those who do not have the presence of mind to rise above the being of the material of sense may proudly assert what they consider to be real and solid, while in truth it is only the play of abstractions that they deal with, so that such boasting is poorest where it fancies itself to be the richest. Rather than apprehending Truth, such an attitude sets itself against the Truth by calling it mere thought, ‘only in the mind’, etc. It is not possible for them to engage in scientific philosophy in which one result proceeds from another by rational necessity because they think that convincing by argument (holding one side against the other) is the natural process for winning Truth. But this is the definition of sophistry, directly the opposite of scientific philosophy in which Truth unveils itself by the rational necessity of its own dialectical development. In fact, Philosophy does also deal with mental entities but at the same time it recognizes thought as the pure essentiality that it is. It is the ignorance of our ‘scientific age’ that we neither appreciate, understand or even know how to comprehend the origin and nature of thought which is so fundamentally essential to human culture. Those who are the most neglectful of such knowledge are at the same time those who most vehemently propound sensuous materialism in the name of realism and seek to annul the place of thought altogether, thus sapping Truth of its own essence. Perceptual understanding holds on to mere abstract fixed essentialities without comprehending their specific determinations, i.e. it apprehends concepts as simple familiarities and therefore does not penetrate into the actual determinateness that constitutes such concepts. In that way it fails to master them; rather such abstract essentialities become the master of this understanding, constraining it to an endless bondage in opposing dualities. By holding on to only one determinateness as truth in opposition to its other and then turning to the opposite one (e.g., as we find in Kant’s antinomies) the ultimate unessentiality of both is established, yet it ignores this fact. What perceptual consciousness should do is accept the unessentiality of both sides and thereby recognize the sublimation of these opposing elements in a higher unity. Instead of doing that, however, it resorts to the in so far as and thus leads itself into abstractions and untruth. (shrink)

Il saggio affronta alcune contraddizioni in cui si trova il complesso mondo delle organizzazioni di volontariato italiane, alle prese con pressioni funzionali che ne modellano la struttura a somiglianza delle organizzazioni politiche e ne orientano l’operato in chiave imprenditoriale.

I explain the charge, and van Inwagen’s response to it, which involves the claim that sentences like ‘There are tables’ shift their truth-conditions (...) between different contexts of utterance. I present an alternative response which involves the negation of that claim, and argue that it is preferable to van Inwagen’s. (shrink)

In this paper, we deal with the issue of contradictory beliefs, particularly with regard to Philosophical Counseling: both voices from the philosophical tradition (with no claim of being exhaustive!) and concepts developed by philosophical practitioners will be considered, in order to make clear what a wide range of resources for dealing with contradictions is available to the philosopher who may wish to engage in Philosophical Counseling. Among the philosophical practitioners, we devote special consideration to Ben Mijuskovic and Gerd Achenbach, and (...) this for two main reasons: first, because the issue of contradiction plays a central role in their concept of Philosophical Counseling and, accordingly, it is given special consideration in their writings; second, because their approaches to Philosophical Counseling are so different that by looking at them one can get an impression of the variety of the positions one can adopt in Philosophical Counseling with respect to the issue of contradiction.

What is it to believe something might be the case? We develop a puzzle that creates difficulties for standard answers to this question. We go on to propose our own solution, which integrates a Bayesian approach to belief with a dynamic semantics for epistemic modals.

There are two ways of understanding the notion of a contradiction: as a conjunction of a statement and its negation, or as a pair of statements one of which is the negation of the other. Correspondingly, there are two ways of understanding the Law of Non-Contradiction (LNC), i.e., the law that says that no contradictions can be true. In this paper I offer some arguments to the effect that on the first (collective) reading LNC is non-negotiable, but on (...) the second (distributive) reading it is perfectly plausible to suppose that LNC may, in some rather special and perhaps undesirable circumstances, fail to hold.

The attitude toward nature in James Thomson’s "The Seasons" has not been duly noted by literary commentators. Instead, the reception of "The Seasons" in modern literary criticism has focused on all sorts of aspects, ranging from visual imagery, to “dislocation, deformity and renewal.” However, when nature as a theme in the poem has been tackled, critics have favored its religious implications—specifically, those pertaining to the historical period in English literature, as well as a number of hypotheses about Thomson’s own relation (...) toward god—over Thomson’s conception of nature on its own terms. Furthermore, none has, in my view, concentrated enough on the most emblematic characteristic of "The Seasons": its unresolved stance toward the natural and its strongly polarized attitude toward it. The aim of this essay is to examine these inconsistencies in order to reveal what they tell us about the period’s changing perspectives, to place "The Seasons"’ reception of the natural in the history of eighteenth-century literature, and to uncover the implications and fertile consequences of Thomson’s view of nature—which spill into para-literary domains.

This article is an inquiry into how the relationship between the principle of non-contradiction and the limits of thought has been understood by thinkers as diverse as Hegel, Heidegger, Levinas, and Graham Priest. While Heidegger and Levinas focus on the question of temporality and Priest takes a formal approach, all these philosophers effectively maintain that the principle of non-contradiction imposes a restriction on thought that disables it from adequately accounting for its own limits and thus what lies beyond (...) those limits, the implication being that the violation of the principle is necessary for such an accounting to take place. However, the ultimate argument here is that, contrary to Priest’s interpretation, Hegel’s philosophy can be convincingly read as supporting the idea that the mind’s ability to go beyond any particular limit of thought can actually be said to involve an adherence to a normative demand to locate and dispel the contradictions that emerge through the very setting of determinative limits. This is a non-formal consistency that evinces a “logic” that is unknowingly followed by the Heideggerian and Levinasian phenomenological philosophies of transcendence. (shrink)

The main task of this work is not to determine the bases for a moral evaluation of the lie; neither is it to describe its negative qualification.

This article explores the force and limitations of Jacques Rancière’s novel attempt to rethink the relationship between aesthetics and politics. In particular, it unravels the paradoxical threads of the fundamental contradiction between two of his steadfast claims: (1) art and politics are consubstantial, and (2) art and politics never truly merge. In taking Rancière to task on this point, the primary objective of this article is to work through the nuances of his project andforeground the problems inherent therein in (...) order to break with the “talisman complex” and the “ontological illusion” of the politics of aesthetics in the name of a new understanding of the social politicity of artistic practices.

The declaration on religious freedom issued by the Second Vatican Council, Dignitatis Humanae claimed: «the human person has a right to religious freedom» (no. 2). Nevertheless, some think the modern declaration of Vatican II contradicts prior Catholic magisterial teaching on religious liberty. I evaluate whether the Magisterium is proposing an inconsistent set of propositions. I argue that a careful reading of the relevant magisterial propositions from classical papal encyclicals, namely, those that apparently opposed religious freedom, reveals they do not contradict (...) any of the propositions concerning religious freedom in the declaration of Vatican II. While proving the absence of a contradiction does not prove that the teaching is true or plausible, there is value in doing so because it allows Catholic theologians to focus on demonstrating that the propositions proposed by the Magisterium are jointly plausible and to propose consistent explanations in which both sets of propositions figure.

Kant’s Formula of Universal Law (FUL) is generally believed to require you to act only on the basis of maxims that you can will without contradiction to become universal laws. In “Contradiction and Kant’s Formula of Universal Law” (2017), I have proposed to read the FUL instead as requiring that, for any maxim on which you act, you can will two things simultaneously, without volitional self-contradiction: (1) willing the maxim as your own action principle and (2) willing (...) that it become a universal law. In the present essay, I reply to comments by Mark Timmons, Michael Walschots, Paola Romero, and Stefano Lo Re. In response to their comments concerning the application of the FUL, I expand the interpretive framework of the Volitional Self-Contradiction Interpretation. I argue that Kant also constructs the diagnostic volitional self-contradiction as a contradiction between (1) willing a tested maxim to become a universal law and (2) willing what humans, qua finite rational beings, necessarily will, namely the means to their actual and possible future ends. I also clarify how the two ways in which Kant specifies the test are related. Furthermore, I clarify the relation between the Volitional Self-Contradiction interpretation and other interpretations of the FUL, in particular the ‘Practical Contradiction’ and ‘Logical Contradiction’ interpretations, as well as its difference from the Golden Rule. I also address the objection that the volitional self-contradiction is superfluous, clarify the relation between the Formula of Universal Law and the Formula of the Law of Nature, and explain why the will of an immoral agent does not contain a volitional self-contradiction of the type at issue.

The question of whether the Pyrrhonist adheres to certain logical principles, criteria of justification, and inference rules is of central importance for the study of Pyrrhonism. Its significance lies in that, whereas the Pyrrhonist describes his philosophical stance and argues against the Dogmatists by means of what may be considered a rational discourse, adherence to any such principles, criteria, and rules does not seem compatible with the radical character of his skepticism. Hence, if the Pyrrhonist does endorse them, one must (...) conclude that he is inconsistent in his outlook. Despite its import, the question under consideration has not received, in the vast literature on Pyrrhonism of the past three decades, all the attention it deserves. In the present paper, I do not propose to provide a full examination of the Pyrrhonist’s attitude towards rationality, but to focus on the question of whether he endorses the law of non-contradiction (LNC). However, I will also briefly tackle the question of the Pyrrhonist’s outlook on both the canons of rational justification at work in the so-called Five Modes of Agrippa and the logical rules of inference. In addition, given that the LNC is deemed a fundamental principle of rationality, determining the Pyrrhonist’s attitude towards it will allow us to understand his general attitude towards rationality.

This essay examine Samuel Beckett's *Trilogy to specify the conditions under which we could make sense of practical necessity. Among other things, I will show how Ajax' must is connected to Mol/oy's attempt to visit his mother and to the need to keep talking that both Molloy and the Unnamable share. I will conclude that their dislocated pursuit of certainty reveal - among other things - how the conditions under which practical necessity can be properly experienced have been extirpated from (...) our social and cultural context. Still, the fact that its vestiges nevertheless subsist provide some reason to regard practical necessity as a constitutive aspect of our agency. This will provide a particular sense in which the Unnamable may coherently claim: "I don't know, I'll never know, in the silence you don't know, you must go on, I can't go on, I will go on.".

Dubilet’s contribution turns to Marx’s “On the Jewish Question” in order to diagnose the collusive interplay between mediation and sovereignty as modes of transcendence that, together, prevent real immanence from irrupting. It does so by recovering the logic of “the general secular contradiction”—the division between the state and civil society that materializes and secularizes the structure of diremption originally articulated in theological form, as the opposition between heaven and earth. In this analysis, the logic of Christianity is shown to (...) be imbricated with the political form of secular modernity itself. Moreover, this account reveals that the modern secular state does not inaugurate the political theology of immanence; rather it constitutes a mechanism of transcendent mediation. The exception that mediates across the two realms renders transcendence livable, but it also reproduces the dirempted life, establishing it as the unsurpassable horizon and foreclosing all operations of dissolution or abolition that could collapse the structure of civil society and the state that governs “the order of the world.” Although immediate transcendence (sovereignty) may be positioned, as it is in the Schmittian paradigm, as radically distinct from its mediational counterpart, in relation to real immanence the two operate as a collusive ensemble.

The contemporary debate centering round the circumference of feminist discourse has of late been very potent in addressing the issues of certain prejudiced notions in our existing patriarchal structure. This paper is an attempt to show the ongoing paradox existing in the world of feminism which has thoroughly critiqued the patriarchal culture and has naturalized sexual identities, thereby glorifying man’s supremacy and dominion. The patriarchal culture lionized the ideals of brevity, courageousness, and intellect and thought of these as the only (...) special possessions of man in society. The qualities of being submissive, kind and caring in nature is considered to be “ideal” and exclusive qualities of a woman. Even though these qualities are “ideal” to women, they are discarded from being considered as universal in nature and are thought of as insignificant in the mainstream societal structure. These qualities are treated as inferior, and exclusively womanly and hence cannot make their stand in the conventional patriarchal social order. For this reason a dilemmatic situation arises here. My effort is to show that this dilemma cannot be exposed in the sense of gender specific human qualities. (shrink)

Abstract. As a general theory of reasoning—and as a general theory of what holds true under every possible circumstance—logic is supposed to be ontologically neutral. It ought to have nothing to do with questions concerning what there is, or whether there is anything at all. It is for this reason that traditional Aristotelian logic, with its tacit existential presuppositions, was eventually deemed inadequate as a canon of pure logic. And it is for this reason that modern quantification theory, too, with (...) its residue of existentially loaded theorems and patterns of inference, has been claimed to suffer from a defect of logical purity. The law of non-contradiction rules out certain circumstances as impossible—circumstances in which a statement is both true and false, or perhaps circumstances where something both is and is not the case. Is this to be regarded as a further ontological bias? (shrink)
