Popper's account of refutation is the linchpin of his famous view that the method of science is the method of conjecture and refutation. This thesis critically examines his account of refutation, and in particular the practice he deprecates as avoiding a refutation. I try to explain how he comes to hold the views that he does about these matters; how he seeks to make them plausible; how he has influenced others to accept his mistakes, and how (...) some of the ideas or responses to Popper of such people are thus similarly mistaken. I draw some distinctions necessary to the provision of an adequate account of the so-called practice of avoiding a refutation, and try to rid the debate about this practice of at least one red herring. I analyse one case of 'avoiding' a refutation in detail to show how the rationality of scientific practice eludes both Popper and many of his commentators. Popper's skepticism about contingent knowledge prevents him from providing an acceptable account of contingent refutation, and so his method is really the method of conjecture and conjecture. He cannot do without the concepts of knowledge and refutation, however, if his account of science is to be plausible or persuasive, and so he equivocates between, amongst other things, refutation as disproof and refutation as the weaker notion of discorroboration. I criticise David Stove's account of this matter, in particular to show how he misses this point. An additional advantage Popper would secure from this equivocation is that if refutations were mere discorroborations they would be easier to achieve, and hence more common in science, than is the case. On Popper's weak notion of refutation, it would be possible to refute true theories since corroboration does not entail truth. There are two other related doctrines Popper holds about refutation which, if accepted, make some refutations seem easier to obtain than is the case. I call these doctrines 'Strong Popperian Falsificationism' (SPF) and 'Weak Popperian Falsificationism' (WPF). SPF is the false doctrine that if a prediction from some theory is refuted then that theory is refuted. Popper does not always endorse SPF. In particular, when confronted with a counterexample to it, he retreats to WPF, which is the false doctrine that if a prediction from some theory is refuted then that theory is prima facie refuted. WPF , or even SPF, can seem plausible if one has in mind predictions derived from theories in strong or conclusive tests of those theories, which I suggest Popper characteristically does. v Popper is disposed to describe any such case of predictive failure which does not lead to the refutation of the theory concerned as one in which that refutation has been avoided. To reinforce his portrayal of the refutation, or the attempted refutation, of major scientific theories as the rational core of scientific practice, Popper treats the so-called practice of avoiding a refutation as untypical of science, and much so-called avoidance he dismisses as unscientific or pseudo-scientific. I argue that his notion of avoiding a refutation is incoherent. Popper is further driven to believe that such avoidance is possible, however, because he conflates sentences with propositions and propositions with propositional beliefs. Also, he wishes to avoid being saddled with the relativisim that is a consequence of his weak account of refutation as discorroboration. Popper believes that ad hoc hypotheses are the most important of the unscientific means of avoiding a refutation. I argue that his account of such hypotheses is also incoherent, and that several hypotheses thought to be ad hoc in his sense are not. Such hypotheses appear to be so largely because of Popper's use of rhetoric and partly because these hypotheses are unacceptable for other reasons. I conclude that to know that a hypothesis is ad hoc in Popper's sense does not illuminate scientific practice. Popper has also attempted to explicate ad hocness in terms of some undesirable, or allegedly undesirable, properties of hypotheses or the explanations they would provide. The first such property is circularity, which is undesirable; the second such property is reduction in empirical content, which is not. In the former case I argue that non-circularity is clearly preferable to non-ad hocness as a criterion for a satisfactory explanation or explanans, as the case may be, and in the latter case that Popper is barking up the wrong tree. Some cases of so-called avoidance are obviously not unscientific. The discovery of Neptune from a prediction based on the reasonable belief that there were residual perturbations in the motion of Uranus is an important case in point, and one that is much discussed in the literature. The manifest failure of astronomers to account for Uranus's motion did not lead to the refutation of Newton's law of gravitiation, yet significant scientific progress obviously did result. Retreating to WPF, Popper claims that Newton's law was prima facie refuted. In general, astronomers have never shared this view, and they are correct in not doing so. I argue that the law of gravitation would have been prima facie refuted only if there had been good reason at the time to believe as false what is true, namely, that an unknown trans-Uranian planet was the cause of those Uranian residuals. Knowledge of the trans-Uranian region was then so slight that it was merely a convenient assumption, one which there was little reason to believe was false, that the known influences on Uranus's motion were the only such influences. I conclude that in believing vi or supposing that it was this assumption that was false, rather than the law of gravitation, Leverrier and Adams, the co-predictors of Neptune, were acting rationally and intelligently. Popper's commentators offer a variety of accounts of the alleged practice of avoiding a refutation, and of this case in particular. I analyse a sample of their accounts to show how common is the acceptance of some of Popper's basic mistakes, even amongst those who claim to reject his falsificationism, and to display the effects on their accounts of this acceptance of his mistakes. Many commentators recognize that anomalies are typically dealt with by changes in the boundary conditions or in other of the auxiliary propositions employed. Where many still go wrong, however, is in retaining the presupposition of WPF which encouraged Popper to hold the contradictory view about anomalies in the first place. Thus Imre Lakatos and others, for example, have developed a 'siege mentality' about major scientific theories; they see them as under continual threat of refutation from anomalies, and so come to believe that dogmatism is essential in science if such theories are to survive as they do. I examine various such doomed attempts to reconcile Popper with the history of science. It is a common failure in this literature to conflate or to fail to see the need to distinguish a belief from a supposition, and an epistemic reason from a pragmatic reason. I argue that only if one does draw these distinctions can one give an adequate account of how anomalies are rationally dealt with in science. The other important strand in Popper's thinking about 'avoidance' of refutation which has seriously misled some of his commentators is his unfounded belief in the dangers of ad hoc hypotheses. I examine the accounts that a sample of such commentators provide of the trans-Uranian planet hypotheses of Leverrier and Adams. These commentators imply or assert what Popper only hints at, namely, that there is something fishy about this hypothesis. I provide a further defence of the rationality of entertaining this hypothesis at the time. I conclude with a few remarks about Popper's dilemma in respect of scientific practice and his long standing emphasis on refutations. (shrink)

Recently, John Fischer has applied Frankfurt’s well-known counter-example to the principle of alternate possibilities to refute the traditional libertarian position which holds that a necessary condition for an agent’s decision (choice) to be free in the sense of freedom required for moral responsibility is that the decision not be causally determined, and that the agent could have avoided making it. Fischer’s argument has consequently led various philosophers to develop libertarian accounts of freedom which try to dispense with the avoidability constraint (...) on freedom. My purpose in this article is to show that Fischer’s attack on traditional libertarianism fails, and, therefore, it is premature to abandon that position. (shrink)

Interpreters of Kant’s Refutation of Idealism face a dilemma: it seems to either beg the question against the Cartesian sceptic or else offer a disappointingly Berkeleyan conclusion. In this article I offer an interpretation of the Refutation on which it does not beg the question against the Cartesian sceptic. After defending a principle about question-begging, I identify four premises concerning our representations that there are textual reasons to think Kant might be implicitly assuming. Using those assumptions, I offer (...) a reconstruction of Kant’s Refutation that avoids the interpretative dilemma, though difficult questions about the argument remain. (shrink)

Plato argues, at Theaetetus 170e-171c, that Protagoras’ relativism is self-refuting. This argument, known as the ‘exquisite argument’, and its merits have been the subject of much controversy over the past few decades. Burnyeat (1976b) has argued in defense of Plato’s argument, but his reconstruction of the argument has been criticized as question-begging. After offering an interpretation of Protagoras’ relativism, I argue that the exquisite argument is successful, for reasons that Burnyeat hints at but fails to develop sufficiently. I consider Protagorean (...) relativism under both of the two possible readings with respect to its scope: global relativism, according to which all truths are only relatively true, and qualified relativism, according to which the relativistic thesis itself is excepted. Taking into consideration some contemporary work on relativism and self-refutation, I show that Plato’s argument succeeds on both of these readings. Given that Protagoras could avoid self-contradiction simply by denying that an enduring subject exists, I argue that the exquisite argument is best understood as confronting Protagoras with a dilemma between self-contradiction and self-defeat of various sorts, all of which lead to the same result, that Protagoras violates the requirements of rational discourse in such a way that he becomes an absurd figure who has nothing to say to us.

What constitutes a good life? A hedonist’s answer to this question is rather simple— more pleasure, less pain. While hedonism was previously a widely accepted belief, it now suffers from several crucial objections. A challenge particularly vexing to hedonists is the Philosophy of Swine: could it be possible that our lives may be less than that of a theoretical swine? In this essay, I argue that lifetime hedonism, the view of hedonism concerned with one’s total lifelong well-being, does not survive (...) this objection. In particular, I will refute the counterarguments that modern-day hedonist, Ben Bramble, presents against the Philosophy of Swine objection. -/- . (shrink)

From my ongoing "Metalogical Plato" project. The aim of the diagram is to make reasonably intuitive how the Socratic elenchos (the logic of refutation applied to candidate formulations of virtues or ruling knowledges) looks and works as a whole structure. This is my starting point in the project, in part because of its great familiarity and arguable claim to being the inauguration of western philosophy; getting this point less wrong would have broad and deep consequences, including for philosophy’s self-understanding. (...) -/- (i.) is the first pass at elenchos in which the Socratic interlocutor does not reflect on knowledge being the crux of the problem. (ii.) is the second, rarer, reflective pass in which they are, making the investigation explicitly about knowledge. Its centrality in the Charmides makes that neglected dialogue of superlative importance. This structure is also the gateway through which the discussion/dialectic crosses into the Agathology (discussion of the form of the good) at Republic 505. -/- The problem of elenchos, then, grasped as a whole structure, is that it seems that knowledge can neither satisfactorily be included in nor excluded from its own scope. The development of the ti esti (“what is ---?”) question leads to the introduction of knowledge into its own scope (i. implicitly, as goodness contrasted with blind rule-following ii. explicitly qua knowledge) while the development of the dual peri tinos (“----about what?) question leads to K’s elimination from its own scope. The introductions are motivated to avoid contradiction, but produce regress; the eliminations are motivated to avoid regress, but produce contradiction. In scholarship, and in the history of philosophy, the ti esti question is universally recognized, to the point of being identified with philosophy’s origin and essence; the peri tinos question is neglected textually and never recognized as the equal dual to the ti esti. This, I claim, has blocked the development of a nontrivial logical appreciation of what Plato's Socrates is up to. (One rather disastrous effect of this neglect is taking Aristotle as the beginning of the development of logic, rather than, correctly, for the beginning of logic’s fatal separation from mathematics and dialectic.) -/- Further, because of this monopticism of the ti esti, the function of consistency in the elenchos has not been understood, even with respect to the ti esti. The ti esti is actually in search of completeness, given a norm of consistency; the peri tinos is in search of consistency, given a norm of completeness. Only appreciating the two questions as dual allows space in the structure to clarify these different orientations relative to consistency. (And, dually, to completeness, whose function in the elenchos is generally entirely missed by scholars and relegated to discussions of eros; it's not out of place there, of course, but its significance is secured here.) Recognizing the duality of the ti esti and peri tinos questions is thus the royal road, in the Socratic-Platonic context, to catching sight of what we post-Cantorians can recognize as the metalogical duality of consistency and completeness. (The salutary disruptive effects of this Plato-Cantor proximity have, of course, been traced in complementary ways by Badiou.) -/- Note that the diagram is supposed to provide a relatively accessible orientation, not to stand on its own, and certainly not to be the last word on any subject. An important qualification (telegraphed in the previous paragraph) is that what elenchos shows is not finally circular or paradoxical, though the problem first presents as such (stubbornly, obdurately, as "difficult" Plato's Socrates always says with characteristic understatement). What is depicted here is meant, at a first pass, to be the shape of that first presentation, the form of the problem of elenchos, rather than of its solution. It's not an accident that this problem strongly resembles "Russell's paradox" (not Russell's not a paradox.) Problem is to solution as RP is to the diagonal theorems. (shrink)

In the debates regarding the ethics of human enhancement, proponents have found it difficult to refute the concern, voiced by certain bioconservatives, that cognitive enhancement violates the autonomy of the enhanced. However, G. Owen Schaefer, Guy Kahane and Julian Savulescu have attempted not only to avoid autonomy-based bioconservative objections, but to argue that cognition-enhancing biomedical interventions can actually enhance autonomy. In response, this paper has two aims: firstly, to explore the limits of their argument; secondly, and more importantly, to develop (...) a more complete understanding of autonomy and its relation to cognitive enhancement. By drawing a distinction between the capacity for autonomy and the exercise and achievement of autonomy and by exploring the possible effects of cognitive enhancement on both competence and authenticity conditions for autonomy, the paper identifies and explains which dimensions of autonomy can and cannot, in principle, be enhanced via direct cognitive interventions. This allows us to draw conclusions regarding the limits of cognitive enhancement as a means for enhancing autonomy. (shrink)

Amartya Sen argues that for the advancement of justice identification of ‘perfect’ justice is neither necessary nor sufficient. He replaces ‘perfect’ justice with comparative justice. Comparative justice limits itself to comparing social states with respect to degrees of justice. Sen’s central thesis is that identifying ‘perfect’ justice and comparing imperfect social states are ‘analytically disjoined’. This essay refutes Sen’s thesis by demonstrating that to be able to make adequate comparisons we need to identify and integrate criteria of comparison. This is (...) precisely the aim of a theory of justice (such as John Rawls’s theory): identifying, integrating and ordering relevant principles of justice. The same integrated criteria that determine ‘perfect’ justice are needed to be able to adequately compare imperfect social states. Sen’s alternative approach, which is based on social choice theory, is incapable of avoiding contrary, indeterminate or incoherent directives where plural principles of justice conflict. (shrink)

German Lutheran scholar Johann Friedrich Weitenkampf (d.1758) sets out to explain and refute the Turkish concept of fate, dividing his dissertation into two sections: the first outlining the Turkish-Muslim view of fate; and the second seeking to prove the invalidity of the Muslim concept of fate with philosophical argumentation. He begins with some brief notes on the historical origin of the Turks, turning then to the backstory of the Qur’an, which he claims can be divided into six sections or topics, (...) the last of which concerns its teachings on fate. According to Weitenkampf, in mainstream Islamic thought, fate is predetermined and immutable. Weitenkampf categorizes most Turks as Jabrites who believe that God is the source of all evil and that men do not have free will. Therefore, men are compelled to do evil or good through God’s omnipotence. He offers examples of how this belief is manifested in the actions and values of the Turks. According to Weitenkampf, since Turks believe in predestination, they do not flee plague-ridden cities or shun contact with those infected. They do not fear death. If they suffer, they believe fate decreed it. In battle, this makes them brave to the point of foolhardy. Weitenkampf also paraphrases an exhortation from the Qur’an in which Muslims are told not to avoid danger, as God has already determined their fate. . . . Weitenkampf’s dissertatio is a symptom of the struggle between the weakened Lutheran orthodoxy and the rise of Pietism and rationalism in the wake of the Enlightenment in the eighteenth century. Unlike other Lutheran authors, he analyzes Islamic thought through systematic philosophical argumentation, deeply influenced by his logic and metaphysics teacher Knutzen, who tried to combine Wolffan Enlightenment rationalism with pietistic spirituality.

A standard problem with the objectivity of social scientific theory in particular is that it is either self-referential, in which case it seems to undermine itself as ideology, or self-excepting, which seem pragmatically self-refuting. Using the example of Marx and his theory of ideology, I show how self-referential theories that include themselves in their scope of explanation can be objective. Ideology may be roughly defined as belief distorted by class interest. I show how Marx thought that natural science was informed (...) by class interest but not therefore necessarily ideology. Capitalists have an interest in understanding the natural world (to a point) so that they can manipulate it for profit. Their survival in the marketplace often depends on their competitive success in doing so. The fact that their interventions into nature, driven by class interest, often succeed, is evidence of the reliability and truth of their natural scientific theories. -/- With social science, capitalists have a partial interest in understanding the world, so that they may maintain their class power, ideological hegemony, and a reasonably stable and self-reproducing economy. Some bourgeois social science, Marx thinks, is therefore vindicated the same way that natural science is, because of, not despite, its success in promoting the class interests that cause it. But the capitalist class, Marx thinks, also has an interest in obfuscating the truth about the social world. It would undermine the stability of capitalism, for example, for the bourgeoisie to adopt what Marx thinks to be the correct social theory, Marxism, and proclaim to the world that capitalism is exploitative and unstable. Capitalism creates a a need for ideological social theories that, driven by class interest, represent capitalism as just, natural, inevitable, and unalterable. If Marxism is correct, while these theories may further capitalist interests, they will not withstand the test of time as capitalist exploitation and instability engenders countersystemic political action. -/- How, then can we know, according to Marx, that Marxism is correct, as applied to itself? In part it is whether it succeeds in further the class interests that cause it. If workers adopt bourgeois theories and Marxism is right, they will find themselves frustrated in pursuit of goals that they have, such as improving their well-being, and if Marxism is wrong, then those theories will help them further their own goals. Similarly with Marxism: if it is right, then workers who adopt it should in the long run have more success in furthering their own goals, and if not, then not. But it is question begging to say that our confidence in the reliability of Marxism is enhanced by its successful promotion of goals that capitalists do not have but (according to Marxism) workers do. To avoid this problem it is necessary to compare the relative success of each sort of theory in promoting the interests and needs that the respective classes have independently of the theory, as well as by the usual criteria of scientific theory choice. -/- Thus the Soviet variant of Marxism was fairly decisively refuted by its failure to generate the support of its own designated constituency necessary to grow and survive. Whether the same is true of other varieties of Marxism or of capitalist social theory, it is, as Zhou En Lai said when asked whether the French Revolution had succeeded, too soon to tell, at least in any definitive way. However, and this is the point of the paper, an objective test of Marxism is possible even though Marxism says that all theory is informed by class interest. The question is whether the interests are in discovering or obfuscating the truth. The point is not limited to Marx, but applies to any self-referential social scientific theory that includes itself in its scope. -/- Keywords: ideology, self-referential theory, self-reference, reliabilism, objectivity, Marx, Marxism, sociology of science, class interest, classes, capitalism, bourgeoisie, workers, working class, social theory of knowledge, confirmation of scientific theory.

According to the principle of epistemic closure, knowledge is closed under known implication. The principle is intuitive but it is problematic in some cases. Suppose you know you have hands and you know that ‘I have hands’ implies ‘I am not a brain-in-a-vat’. Does it follow that you know you are not a brain-in-a-vat? It seems not; it should not be so easy to refute skepticism. In this and similar cases, we are confronted with a puzzle: epistemic closure is an (...) intuitive principle, but at times, it does not seem that we know by implication. In response to this puzzle, the literature has been mostly polarized between those who are willing to do away with epistemic closure and those who think we cannot live without it. But there is a third way. Here I formulate a restricted version of the principle of epistemic closure. In the standard version, the principle can range over any proposition; in the restricted version, it can only range over those propositions that are within the limits of a given epistemic inquiry and that do not constitute the underlying assumptions of the inquiry. If we adopt the restricted version, I argue, we can preserve the advantages associated with closure, while at the same time avoiding the puzzle I’ve described. My discussion also yields an insight into the nature of knowledge. I argue that knowledge is best understood as a topic-restricted notion, and that such a conception is a natural one given our limited cognitive resources. (shrink)

Abū Ishāq al-Ṣaffār was one of scholars of the Western Qarakhānids’ period who followed the Kalām thought of al-Māturīdī (d. 333/944). His theological works Talkhīs al-adilla and Risāla fī al-kalām, his method in kalām, and frequent reference to his works by Ottoman and Arab scholars indicate that al-Ṣaffār is a respected and authorative Māturīdī theologian. The article focuses on his defense of the kalām. By adding a long introduction to Talkhīs about the naming, importance, and religious legitimacy of the science (...) of kalām, Saffār asserted that the kalām should be learned. When systematical vindication of the science of kalām is examined, it is understood that al-Ṣaffār is the first theologian who reserved a private and voluminous part for defensing the kalām among Ḥanafī-Māturīdīs. Even though he does not state its systematic, it can be understood that vindication of kalām in al-Ṣaffār divides into three parts as of explanation, demonstration and refutation. Al-Ṣaffār’s defending the science of kalām shows that there were opposite thoughts against kalām in the 4th/10th and 5th/11th centuries throughout in Transoxania. In this period Aṣḥāb al-Ḥadīth and Ikhwān al-Ṣafāʾ were the opposite fronts of kalām. In addition, he was trying to go beyond the oppositions of Ḥanafī jurists. His vindication is consistent and has scholarly depth because it is able to be against a strong opposition. -/- SUMMARY: Abū Ishāq Ibrahīm b. Ismāil Zāhid al-Ṣaffār al-Bukhārī is a scholar belonging to the Ḥanafī theological tradition which was improved by the contribution of Ḥanafī theologians who used thinking system of Abū Ḥanīfa (d. 150/767) as base and adopted Abū Manṣūr al-Māturīdī (d. 333/944) and his thoughts in historical process. The contents of his theological works Talkhīs al-adilla li-qawāʿid al-tawḥīd and Risāla fī al-Kalām, the method that he used, and references to his works made by Ottoman and Arab scholars indicate that he is an important Māturīdī theologian. The article focuses on his defense of the science of Kalām. -/- In Talkhīs al-adilla, there are two sections including the subject of naming, and importance and necessity of Kalām discipline. Here, the necessity of learning Kalām and its value are defended in detail. -/- Besides, rumors “Abū Ḥanīfa turned away from the science of Kalām in his doomsdays” and that “He prohibited to make occupation with Kalām completely” are evaluated. -/- When systematical vindication of the science of Kalām is examined, it is understood that al-Ṣaffār is the first theologian who reserved a private and voluminous part for defensing the Kalām among Ḥanafī Māturīdīs. Even if Abū Manṣūr al-Māturīdī, Abū al-Yusr al-Bazdawī (d. 493/1100) and Abū Muʿīn al-Nasafī (d. 508/1115) defend that the science of Kalām is not wrong for religion; yet, the vindication of Kalām does not take a place under a separate title and in a detailed manner in any of Māturīdī theologians works. -/- The method that al-Ṣaffār used when he is defending the science of Kalām, differs from strategy of Abū Ḥanīfa. While Abū Ḥanīfa has mentioned that there is a need for the science of Kalām under these new circumstances, al-Ṣaffār has defended theologians who were charged with being Ahl al-Bidaʿ, by trying to prove that the prophets especially the Prophet Ibrāhīm, even the Companions of the Prophet Muḥammad (Ṣaḥāba) and the Successors of the Companions (Tābiʿūn) scholars use their minds and make arguments in religious matters. In this respect, he emphasizes that the Qurʾān orders to think and discuss gently, not to be stay in silence: “And dispute with them, using what is best” (16.125-126). Therefore, he states that this discipline which took a mission to explain and defend the creed of Islam (ʿaqīda), cannot be characterized as an innovation (bidʿah) or illicit. -/- His vindication method can be defined as a more developed type of method that Abu’l-Ḥasan al-Ash’arī’s (d. 324/935) used in Risāla fī istiḥsān al-khawḍ fī ʿilm al-kalām. Even though he does not state its systematic, it can be understood that vindication of Kalām in al-Ṣaffār divides into three parts as of explanation, demonstration and refutation: -/- a) Explanation: Explaining the necessity and importance of the science of Kalām by giving information about its definition, names, value and place among other principles. -/- b) Demonstration: Revealing the religious basics of the science of Kalām from the Qurʾān, the Sunna of the Prophet Muḥammad, the Companions of the Prophet, and the Successors of the Companions thus specifying that it is legitimate for religion. -/- c) Refutation: Replying the claims having aim to weaken the value of Kalām principle and its religious legality. -/- Al-Ṣaffār describes ‘the science of Kalām’ as ‘Knowing the Real with the evidences which help to reach the absolute information’. By allocating the concept of 'Ḥaqq', he repeats the definition of Kalām as “it is to know God with certain evidences” in a part of his work, and “it is to know the principles of religion (uṣūl al-dīn) with certain evidences” in another part. He describes Kalām as “Knowing ḥaqq / God / uṣūl al-dīn by depending on evidence”, and tries to prove that it is wrong to consider a science which performs the stated duty, as illicit and abominable and thus turn away from it. -/- Al-Ṣaffār thinks that it is right to call this principle as ‘Kalām’ because of the certain evidences leading to the truth that this science has used. This thought was defended by other theologians as well. -/- For example, according to Saʿd al-Dīn Masʿūd al-Taftazānī (d. 792/1310) it seems like to say “This is the word (kalām), not the other knowings” by the way of the power of evidences used in Kalām.Thus, it is appropriate to give name Kalām for this science which based on certain evidences. -/- Al-Ṣaffār’s explanations revealed in scope of vindication of the Kalām are adopted by some of following scholars. Ḥusām al-Dīn al-Sighnāqī (d. 714/1314) in his book called al-Tasdīd sharḥ al-Tamhīd fī qawāʿid al-tawḥīd quotes Saffâr’s explanations as the same. -/- Al-Ṣaffār indicates that the method told in the Qurʾān is to reply questions about religion, beliefs and rejection instead of remaining in silence. The duty taken on by Kalām is this vindication activity performed by the prophets whose examples are described in the Qurʾān and which is legal and demanded. His way of thinking and vindication of the Kalām resembles that of Abū Manṣūr al-Māturīdī. Al-Māturīdī says, “Prophets and we were ordered to invite infidels to Islam. When this invitation happens, the respondents will ask for evidence and explanation, and discussion will be inevitable. Therefore, discussing and talking about subjects of Kalām is not objectionable”. -/- Thoughts of al-Māturīdī and al-Ṣaffār regarding the vindication of the Kalām were repeated by Nūr al-Dīn al-Ṣābūnī (d. 580/1184), and Fakhr al-Dīn al-Rāzī (d. 606/1210) later. According to al-Ṣābūnī, the evidences put against deniers and especially the discussion made by the Prophet Ibrāhīm to defend his own belief, prove the legality of Kalām discipline. Likewise, according to al-Rāzī, the duty of Kalām is just an activity performed already in the Qurʾān and ordered to the prophets. At this point of view, since the prophets were leading to Kalām, banning this activity is nonsense. -/- According to al-Ṣaffār, the reason for why Abu Hanifa avoids his son Hammād from these discussions is that Abu Hanifa does not like discussions based on obstinate. Otherwise, it cannot be that Abū Ḥanīfa prohibits to learn Kalām and make discussion about Kalām. According to him, this behavior of Abū Ḥanīfa results from that people discussing with him are ignorant about the subject of Kalām, discussion turns to an obstinate, and coming to an end of discussion seems impossible. This comment of al-Ṣaffār is quoted in Miftāḥ al-saʿāda wa-miṣbāḥ al-siyāda by ʿIṣām al-Dīn Aḥmed b. Muṣṭafā Tashköprüzāde (d. 968/1561) and in Minaḥ al-rawḍ al-azhar fī sharḥ al-Fiqh al-akbar by ʿAlī b. Sulṭān Muḥammad al-Qārī (d. 1014/1606) as same as his words. -/- Al-Ṣaffār’s defending the science of Kalām shows that there were opposite thoughts against Kalām in the 4th/10th and 5th/11th centuries throughout in Transoxania.In this period Aṣḥāb al-Ḥadīth and Ikhwān al-Ṣafāʾ were the opposite fronts of Kalām. In addition, he was trying to go beyond the oppositions of Ḥanafī jurists (fuqahāʾ). Because some of the Ḥanafī jurists thought that Abū Ḥanīfa forsook occupation with the science of Kalām and even he prohibited his son to have interest in this discipline. But some of Ḥanafī theologians such as al-Māturīdī, al-Nasafī and al-Ṣaffār protested this thought which describes Abū Ḥanīfa as a banner for Kalām. -/- His vindication is consistent and has scholarly depth because it is able to be against a strong opposition. -/- His book Talkhīs al-adilla li-qawāʿid al-tawḥīd is a unique source in terms of containing vindication of the Kalām in detail and also influencing the approaches of the next period scholars.

Branden Thornhill-Miller and Peter Millican as well as Janusz Salomon put forward versions of supernaturalism that avoid the existence of a religion which alone provides the true revelation and the only way to salvation and which teaches that God acted in this world. Their rejection of revealed, exclusive religion is based on an argument from religious diversity and an argument from natural explana- tions of religious phenomena. These two together form the ‘common-core/diversity dilemma’. In this article I refute these two (...) arguments by arguing that explaining the origin of belief in supernatural agents does not provide a reason for not believing in the existence of supernatural agents.

This project investigates naturalized metaphysics as a recent trend in analytic metaphysics originating in the naturalist attitude of James Ladyman and Don Ross in their seminal work Everything must Go: Metaphysics Naturalized (2007). The primary focus, however, will be the more recent article “Neo-Positivist Metaphysics” (2012) by Alyssa Ney that originates in this tradition. The project will conclude that naturalized metaphysics is an unsuccessful attempt at an answer to the question ’how is metaphysics possible’. More precisely, the project will establish (...) that any answer to this question must instruct how to succeed at attempts at assertions about the Kantian thing in itself. This requirement is the result of an argument that no other conception of ’reality’ is robust enough to accommodate an ambitious metaphysics. Subsequently, it will be argued that naturalized metaphysics is conceived by its proponents as an attempt at such an answer, but that naturalized metaphysics does not provide the required instruction. This problem occurs because of Carnap’s challenge to metaphysics. Carnap observes that no assertion can be made outside a linguistic framework which has the consequence that metaphysical assertions must be about the conceptual conventions of the linguistic framework rather than the thing in itself. It is the view of Ney and the other proponents of naturalized metaphysics that metaphysics is possible as a naturalized metaphysics; a metaphysics that appropriately defers or yields to the findings of science. The project argues that this requirement does nothing to ensure that Carnap’s challenge is avoided. The challenge is equally significant to naturalized and non-naturalized metaphysics, so long as both require that successful attempts at metaphysics must be assertions about the thing in itself. -/- The project concludes that until or unless Carnap’s challenge is refuted, naturalized metaphysics remain impossible, just like the metaphysics it is supposed to replace.

Lester‘s reply to the review by Gordon and Modugno of Escape from Leviathan was due to appear in a later edition of the same periodical, but it was eventually dropped without notice or a reason being given. Subsequently, their review has occasionally been cited in isolation as a refutation of that book‘s theory of liberty, the compatibility of such liberty with welfare maximisation, and the use of "Popperian views" as though a complete reply did not exist and were not (...) freely available and easily found online. To make it harder to avoid the reply, whether by accident or design, it is reproduced here (but with sundry small emendations for greater clarity). (shrink)

In the first stage of his thinking Karl Marx founded his revolutionary politics on philosophical speculation, while in the second (mature) stage he relied on economics and the theory of exploitation based on his theory of surplus value. Marxism, however, developed in the opposite direction. After Marx's economic doctrine became vulnerable to powerful objections, Marxists tried to find a refuge in his early philosophical writings and in this way avoid refutation. Ultimately this attempt proved unsuccessful too.

The aim of the paper is to critically assess the idea that reasons for action are provided by desires (the Model). I start from the claim that the most often employed meta-ethical background for the Model is ethical naturalism; I then argue against the Model through its naturalist background. For the latter purpose I make use of two objections that are both intended to refute naturalism per se. One is G.E. Moore’s Open Question Argument (OQA), the other is Derek Parfit’s (...) Triviality Objection (TO). I show that naturalists might be able to avoid both objections if they can vindicate the reduction proposed. This, however, leads to further conditions whose fulfillment is necessary for the success of the vindication. I deal with one such condition, which I borrow from Peter Railton and Mark Schroeder:the demand that naturalist reductions must be tolerably revisionist. In the remainder of the paper I argue that the most influential versions of the Model are intolerably revisionist. The first problem concerns the picture of reasons that many recent formulations of the Model advocate. By using an objection from Michael Bedke, I show that on this interpretation obvious reasons won’t be accounted for by the Model. The second problem concerns the idealization that is also often part of the Model. Invoking an argument of Connie Rosati’s, I show that the best form of idealization, the ideal advisor account, is inadequate. Hence, though not the knock down arguments they were intended to be, OQA and TO do pose a serious threat to the Model. (shrink)

The two principal models of design in methodological circles in architecture—analysis/synthesis and conjecture/analysis—have their roots in philosophy of science, in different conceptions of scientific method. This paper explores the philosophical origins of these models and the reasons for rejecting analysis/synthesis in favour of conjecture/analysis, the latter being derived from Karl Popper’s view of scientific method. I discuss a fundamental problem with Popper’s view, however, and indicate a framework for conjecture/analysis to avoid this problem.

This chapter constructs the argument that corporate and political policies known to accelerate anthropogenic global warming, and subsequent climate change, constitute crimes against humanity—predicated on failures to avoid reasonably foreseeable threats to sustained human existence. Given the moral gravity of crimes against humanity it follows that financial divestment is ethically obligatory for institutions wishing to avoid moral association. The moral case for fossil fuel divestment, in the wake of such crimes, derives from (a) the ethical implications of negative responsibility, or (...) what constitutes culpability by omission; (b) institutional collaboration based upon immediate financial interests tied to climate inaction; and (c) institutional complicity derived from financial support of corporate behaviors that hasten global warming. Possible objections are examined and refuted. (shrink)

This article aims to refute the “incompatibility thesis” that nationalism is incompatible with transnational feminist solidarity, as it fosters exclusionary practices, xenophobia, and racism among feminists with conflicting nationalist aspirations. I examine the plausibility of the incompatibility thesis by focusing on the controversy regarding just reparation for Second World War “comfort women,” which is still unresolved. The Korean Council at the center of this controversy, which advocates for the rights of Korean former comfort women, has been criticized for its strident (...) nationalism and held responsible for the stalemate. Consequently, the case of comfort women has been thought to exemplify the incompatibility thesis. I argue against this common feminist perception in three ways: first, those who subscribe to the incompatibility thesis have misinterpreted facts surrounding the issue; second, the Korean Council's nationalism is a version of “polycentric nationalism,” which avoids the problems of essentialist nationalism at the center of feminist concerns; and, third, transnational feminist solidarity is predicated on the idea of oppressed/marginalized women's epistemic privilege and enjoins that feminists respect oppressed/marginalized women's epistemic privilege. To the extent that oppressed/marginalized women's voices are expressed in nationalist terms, I argue that feminists committed to transnational feminist solidarity must accommodate their nationalism.

Primarily using philosophy, but also some social science, Escape from Leviathan (EfL) explains and defends what it calls an extreme version of the implicit ‘classical liberal compatibility thesis’: liberty, welfare, and anarchy are overwhelmingly complementary in normal practice (rationality is added for its intimate theoretical connections to these categories). This is done using theories, not definitions, of each concept. This important thesis is entirely positive. Therefore, somewhat unusually, all normative issues are avoided as irrelevant distractions in this context. In addition, (...) the epistemology used is also unorthodox. A justificationist, or foundationalist, approach would be literally illogical: the self-refuting trilemma faced by ‘supporting justifications’ (as regards arguments and evidence) is of entailing infinite regresses, dogmatic starting points, or circularities. Consequently, critical rationalism is assumed: conjecture and criticism are all that is possible. Thus all aspects of the conjectured thesis are explained and defended from criticism as thoroughly as the book can encompass. It is concluded that the thesis has not been refuted and so may be critically preferred. (However, this could all still be viewed as a ‘justification’ by those thus inclined.) All of this is made clear enough in the short introductory chapter and repeated where relevant throughout. Yet some reviews do not have a firm grasp of the specific project and so reject it with unsound criticisms. We now turn to one such example. (shrink)

What is paradoxical about the Socratic paradoxes is that they are not paradoxical at all. Socrates famously argued that knowledge is sufficient for virtue and that no one errs willingly. Both doctrines are discussed in the Protagoras between Socrates and the Abderian sophist, however the argumentative line that Socrates chooses to follow in order to refute ‘the many’ has raised a serious degree of controversy among scholars. Is Socrates upholding the hedonistic view? Or, is he only trying to show the (...) bankruptcy of the explanation of akrasia as ‘being overcome by pleasure’ which ‘the many’ advocate? Socrates intends to do the latter, showing that this hedonistic explanation of akrasia leads to absurdity. Plato’s and Socrates’ identification of goodness with pleasure would mark a sudden and unexplained departure from their moral theories, and would render the Socratic denial of akrasia an argument with limited range –only for those assuming hedonism. If we are correct to hold that Socrates does not intend to identify the good with the pleasant, then we are immediately put against a new and much more difficult challenge; that is, to suggest how the Socratic denial of akrasia could regain its catholic plausibility against the commonsensical stance to akrasia, namely that people act against their best judgment due to their impotence to resist to motivational forces such as pleasure, pain, fear, passion and love. Socrates does not offer any other explicit account –apart from the hedonistic one- of how his doctrine could be catholically defended; hence the task of decoding the Socratic line of thought is far from an easy one. The key move in order to decode the puzzling Socratic doctrine is to understand how Socrates treats the notion of ‘knowledge’. For Socrates, moral knowledge is distinguished from mere belief; in this sense, only knowledge has the commanding power which enables one to sustain his best evaluative judgment against other motivational forces and only knowledge is sufficient for the virtuous conduct. By contrast, as mere belief is susceptible to other motivational forces like pleasure, pain, fear, etc. its possessor will, in turn, be susceptible to the revision of his intentions which derive from his best value judgment. In the Protagoras, Socrates implies that intentions grounded on belief can be ‘dragged around’ by desire; and according to my view in this paper, this Socratic stance allows a non-epistemic interpretation of his thesis. According to the traditional epistemic interpretation of the Socratic denial of akrasia, one’s wrongdoing is always a miscalculation that takes place on his practical syllogism. However, my understanding of the Socratic denial of akrasia allows cases of one even going against his best judgment, when his judgment is based on belief. In that sense, a judgment grounded on belief has insufficient power to guarantee that the chosen action will follow, whereas only judgments grounded on knowledge have a commanding and lordly power. For Socrates, everyone always goes for the good but only those with knowledge can infallibly discover and act on the good. Those with mere belief can only reach an apparent good, which may be good or bad. The motivation for the good is not unshakeable for those with mere belief since the grounding of their belief is scarcely strong enough to hold on the correct intention. Socrates therefore holds that the grounding of knowledge influences the motivational state of the moral agent. Thereupon, my interpretation differs from others in suggesting that for Socrates not all the cases of akrasia are cognitive mistakes in their judgment. Rather I hold, in opposition to the received stance on akrasia, that Socrates allows that one could act against his best judgment, when the latter is grounded on mere belief. (shrink)

There are at least three interpretations that attempt to read from the Sense-Certainty Chapter a Hegelian theory of indexicals. First, the Impossibility of Singular Reference Reading understands Hegel as excluding in principle the possibility of any linguistic cognition of individuals. Second, the Theory of Reference Reading criticizes the first reading and interprets from Hegel the classical idea of direct reference theory. Third, Brandom’s Anaphoric Theory Reading suggests an alternative explanation while still defending the possibility of knowledge of individuals in Hegel. (...) I criticize the first two readings and argue that the third is the most exegetically and philosophically adequate interpretation. The first interpretation attempts to ascribe to Hegel a sort of skepticism, but this can be at most in a very restricted sense successful and the skepticism constructed in such a way is too trivial to refute Hegel’s position. The second reading is more adequate in that it does not fall into the error that the first one committed, but is still flawed because it introduces a subject-object or mind-world dualism that Hegel denies. The third reading has great advantages compared to the first two readings in terms that it provides a suitable account of indexical knowledge on individuals while avoiding skepticism and dualism which arise in the former readings.

This chapter analyzes two short texts in which Peirce sketches out an anti-skeptical argument inspired by Kant’s refutation of idealism. The chapter will first consider why Peirce found Kant’s argument interesting and promising, given that it is often regarded as problematic and unsuccessful. It will then briefly reconstruct Kant’s refutation, highlighting its most problematic passages. Moreover, since Peirce’s own version of the argument relies on Kant’s views regarding the temporal structure of consciousness, the chapter will explain how Peirce (...) tackles this issue in “The Law of Mind.” Finally, the chapter considers Peirce’s own anti-skeptical argument and examines whether and how it can be seen as appropriating Kant’s strategy.

The paper deals with an argument reported by Razi (d. 1210) that was used to attempt to refute the immateriality of human nature. This argument is based on an epistemic asymmetry between our self-knowledge and our knowledge of immaterial things. After some preliminary remarks, the paper analyzes the structure of the argument in four steps. From a methodological point of view, the argument is similar to a family of epistemological arguments (notably, the Cartesian argument from doubt) and is vulnerable to (...) the same objection that can be raised against that form of reasoning. The last section points out that the argument can be used indirectly to highlight the weakness in some arguments for the claim that there is something immaterial in human beings. (shrink)

The Doctrine of Double Effect [DDE] states roughly that it is harder to justify causing or allowing harm as a means to an end than it is to justify conduct that results in harm as a side effect. This chapter argues that a theory of deontological constraints on harming needs something like the DDE in order to avoid the charge that it reflects a narcissistic obsession with the cleanliness of our own hands. Unfortunately, the DDE is often interpreted as maintaining (...) that we must avoid acting with certain intentions, which, this chapter contends, embodies an equally narcissistic obsession with the purity of our own hearts. The chapter argues that the DDE is better interpreted as a denial of the Machiavellian idea that beneficial ends justify harmful means. On this view, the objective fact that our conduct will secure benefits for some individuals at the expense of other individuals weakens the extent to which those benefits count as reasons to engage in that conduct. The chapter argues that this version of the DDE provides a plausible, non-narcissistic foundation for deontological constraints. (shrink)

In this paper I will develop a lambda-term calculus, lambda-2Int, for a bi-intuitionistic logic and discuss its implications for the notions of sense and denotation of derivations in a bilateralist setting. Thus, I will use the Curry-Howard correspondence, which has been well-established between the simply typed lambda-calculus and natural deduction systems for intuitionistic logic, and apply it to a bilateralist proof system displaying two derivability relations, one for proving and one for refuting. The basis will be the natural deduction system (...) of Wansing's bi-intuitionistic logic 2Int, which I will turn into a term-annotated form. Therefore, we need a type theory that extends to a two-sorted typed lambda-calculus. I will present such a term-annotated proof system for 2Int and prove a Dualization Theorem relating proofs and refutations in this system. On the basis of these formal results I will argue that this gives us interesting insights into questions about sense and denotation as well as synonymy and identity of proofs from a bilateralist point of view.

RésuméJe me penche sur un aspect de la philosophie sociale de Popper, à savoir les principes d'évaluation des interprétations historiques. Ma thèse globale est que suivant la perspective poppèrienne, notre choix parmi des interprétations historiques doit user d'au moins deux des critères qu'applique Popper au choix parmi diverses théories scientifiques : une interprétation devrait logiquement se prêter à une réfutation et elle devrait être consistante. Afin de montrer la pertinence et la fécondité de cette approche, je me concentre sur l'interprétation (...) historique des causes de la montée du nazisme que propose Erich Fromm, en particulier dansEscape from Freedom.Je montrerai que l'application de notions psychanalytiques dans le cadre de son interprétation historique a une valeur explicative faible, voire nulle. Son échec à expliquer certaines questions sociales tient à plusieurs raisons. Premièrement, l'auteur ne fournit pas, quoi qu'il en dise, d'explication causale convaincante. Ensuite, les concepts et les multiples hypotheèsesad hocauxquels il a recours tendent è rendre son interprétation irréfutable. Enfin, Fromm s'appuie sur des assomptions théoriques contradictoires. Mon analyse est basée sur la notion fondamentale de Popper voulant que la connaissance scientifique empirique exige au strict minimum une ouverture des interprétations historiques à la critique intersubjective. C'est cette exigence qui permet de les critiquer — c'est-à-dire les accepter, les réfuter et les corriger — sur une base rationnelle. (shrink)

One guide to an argument's significance is the number and variety of refutations it attracts. By this measure, the Dutch book argument has considerable importance.2 Of course this measure alone is not a sure guide to locating arguments deserving of our attention—if a decisive refutation has really been given, we are better off pursuing other topics. But the presence of many and varied counterarguments at least suggests that either the refutations are controversial, or that their target admits of more (...) than one interpretation, or both. The main point of this paper is to focus on a way of understanding the Dutch Book argument (DBA) that avoids many of the well-known criticisms, and to consider how it fares against an important criticism that still remains: the objection that the DBA presupposes value-independence of bets.

In the ‘Refutation of Idealism’ chapter of the first Critique, Kant argues that the conditions required for having certain kinds of mental episodes are sufficient to guarantee that there are ‘objects in space’ outside us. A perennially influential way of reading this compressed argument is as a kind of causal inference: in order for us to make justified judgements about the order of our inner states, those states must be caused by the successive states of objects in space outside (...) us. Here I consider the best recent versions of this reading, and argue that each suffers from apparently fatal flaws. -/- . (shrink)

Causal refutations of external-world scepticism start from our ability to make justified judgements about the order of our own experiences, and end with the claim that there must be perceptible external objects, some of whose states can be causally correlated with that order. In a recent paper, I made a series of objections to this broadly Kantian anti-sceptical strategy. Georges Dicker has provided substantive replies on behalf of a version of the causal refutation of idealism. Here I offer a (...) few final remarks about issues at the heart of our disagreement. -/- . (shrink)

Socrates’ refutations of Thrasymachus in Republic I are unsatisfactory on a number of levels which need to be carefully distinguished. At the same time several of his arguments are more powerful than they initially appear. Of particular interest are those which turn on the idea of a craft, which represents a shared norm of practical rationality here contested by Socrates and Thrasymachus.

It is argued that although George Bealer's influential ‘Self-Consciousness argument’ refutes standard versions of reductive functionalism (RF), it fails to generalize in the way Bealer supposes. To wit, he presupposes that any version of RF must take the content of ‘pain’ to be the property of being in pain (and so on), which is expressly rejected in independently motivated versions of conceptual role semantics (CRS). Accordingly, there are independently motivated versions of RF, incorporating CRS, which avoid Bealer's main type of (...) refutation. I focus particularly on one such theory, which takes concepts to be event types that are individuated by their psychological roles, which has the resources of responding to each of the more specific worries Bealer expresses.

My purpose is to refute the intentionalist approach to perception. Drawing from mainstream literature, I identify a principle on which any version of intentional theory relies. My paper is a detailed attack on the truth of the principle. In the first section I will introduce terminology and will taxonomize various statements of the intentional view. In the second section I will briefly outline a sketch of the skeletal intentionalist theory that develops from the assumption of the principle alone. Then, in (...) the third section, I will advance my reasons against this theory. In the fourth section, I will set forth anintuitive and definitive counterexample to the adequacy of the principle of intentionalism to accounting for ordinary perception. Moving from this, in the fifth section, I will provide some reasons explaining why intentionalism is condemned at being unsuccessful. Finally, in the last section of the paper, I will give my conclusions. (shrink)

Both the pessimistic inductions over scientific theories and over scientists are built upon what I call proportional pessimism: as theories are discarded, the inductive rationale for concluding that the next theories will be discarded grows stronger. I argue that proportional pessimism clashes with the fact that present theories are more successful than past theories, and with the implications of the assumptions that there are finitely and infinitely many unconceived alternatives. Therefore, the two pessimistic inductions collapse along with proportional pessimism.

This paper claims that Socrates’ refutation of Gorgias in the eponymous dialogue is designed not to find out the truth about the nature of the art of rhetoric itself but to refute the master of rhetoric himself. I try to justify this claim by displaying some major contradictions between the conclusions reached at with Gorgias and those reached at with Polus. When these contradictions are taken into account, the discussion with Polus is to be seen as reflecting the genuine (...) Socratic position about rhetoric, whereas the discussion with Gorgias seems only to be devised as a dexterity in refutation. (shrink)

The aim of this paper has been to present a new reconstruction of Kant’s Refutation of Idealism. I have considered several different targets of the Refutation, five of them mentioned by Kant himself. I believe that I have shown that the Refutation of Idealism is best considered only as a sound argument against Mendelssohnian subjectivist idealism, against Mendelssohnian immaterialism, and against Mendelssohnian realist idealism. First, Kant’s Refutation is a sound argument in favor of the claim that (...) the outer things represented in our minds are real rather than ideal; that is, they exist mind-independently as noumena. And second, Kant’s refutation is a sound argument for a fundamental ontology of noumena: the ultimate nature of reality and of our minds is neither material nor mental but made up of things in themselves.

The first article in this issue attempts to refute the concept of Altruism and calls it akin to Selfishness. The arguments are logically set in the way like that of Spinoza’s method of demonstration, with Axioms, Definitions, Propositions and Notes: so as to make them exact and precise. Interestingly, the writer introduces a new concept of Credit and through various other original propositions and examples rebuts the altruistic nature which is generally ascribed to humans.

This paper questions the veracity of Ferdinand de Saussure's theory of the genitive absolute in Sanskrit as giving rise to his erroneous theories of language. The paper begins by reviewing the received opinions about the arbitrary relationship between a sign and what is signifies. Then engaging with the works of St. Augustine and Tantric texts and reading the works of Saussure, the paper shows how higher academia has bought into Saussure's polemics which have nearly destroyed authentic philosophizing. The first title (...) chosen for this essay was The Refutation of Saussure's the 'Genitive Absolute' as a Foundation for Interreligious Dialogue. This title was discarded because though this essay closely reads Saussure's monograph on the genitive absolute in Sanskrit, most readers would be more familiar with his General Course. But without reading his comments on the genitive absolute in Sanskrit, one cannot understand the gravity of his errors. (shrink)

I’m to push back on Hill’s (2022) criticism in four ways. First: we need some context for the debate that occurred in the pages of the Social Epistemology Review and Reply Collective that so concerns Hill.

Third: I address Hill’s claim there is no evidence George W. Bush or Tony Blair accused their critics, during the build-up (...) the invasion of Iraq in 2003ACE, as being “conspiracy theorists.” Fourth (and finally): I will gently suggest that Hill has succumbed to a stereotypical view of work in Philosophy on conspiracy theories.

Research ethics committees must sometimes deliberate about objects that do not fit nicely into any existing category. This is currently the case with the “gastruloid,” which is a self-assembling blob of cells that resembles a human embryo. The resemblance makes it tempting to group it with other members of that kind, and thus to ask whether gastruloids really are embryos. But fitting an ambiguous object into an existing category with well-worn pathways in research ethics, like the embryo, is only a (...) temporary fix. The bigger problem is that we no longer know what an embryo is. We haven’t had a non-absurd definition of ‘embryo’ for several decades and without a well-defined comparison class, asking whether gastruloids belong to the morally relevant class of things we call embryos is to ask a question without an answer. What’s the alternative? A better approach needs to avoid what I’ll refer to as “the potentiality trap” and, instead, rely on the emergence of morally salient facts about gastruloids and other synthetic embryos. (shrink)

In Languages of Art, Nelson Goodman presents a general theory of symbolic notation. However, I show that his theory could not adequately explain possible cases of natural language notational uses, and argue that this outcome undermines, not only Goodman's own theory, but any broadly type versus token based account of notational structure.Given this failure, an alternative representational theory is proposed, in which different visual or perceptual aspects of a given physical inscription each represent a different letter, word, or other notational (...) item. Such a view is strongly supported by the completely conventional relation between inscriptions and notation, as shown by encryption techniques etc. (shrink)

Descartes argues that, apart from the existence of a veracious God, we can have no reason to believe that we possess reliable cognitive faculties, with the result that, if atheism is true, not even our seemingly most certain beliefs can count as knowledge for us. Since the atheist denies the existence of God, he or she will be precisely in this position. I argue that Descartes' argument is sound, and that atheism is therefore self-refuting.

Dirac’s relativistic theory of electron generally results in two possible solutions, one with positive energy and other with negative energy. Although positive energy solutions accurately represented particles such as electrons, interpretation of negative energy solution became very much controversial in the last century. By assuming the vacuum to be completely filled with a sea of negative energy electrons, Dirac tried to avoid natural transition of electron from positive to negative energy state using Pauli’s exclusion principle. However, many scientists like Bohr (...) objected to the idea of sea of electrons as it indicates infinite density of charge and electric field and consequently infinite energy. In addition, till date, there is no experimental evidence of a particle whose total energy (kinetic plus rest) is negative. In an alternative approach, Feynman, in quantum field theory, proposed that particles with negative energy are actually positive energy particles running backwards in time. This was mathematically consistent since quantum mechanical energy operator contains time in denominator and the negative sign of energy can be absorbed in it. However, concept of negative time is logically inconsistent since in this case, effect happens before the cause. To avoid above contradictions, in this paper, we try to reformulate the Dirac’s theory of electron so that neither energy needs to be negative nor the time is required to be negative. Still, in this new formulation, two different possible solutions exist for particles and antiparticles (electrons and positrons). (shrink)

According to standard trope nominalism, there are simple tropes that do not have parts or multiply distinct aspects. Douglas Ehring’s reductio ad absurdum against this standard view concludes that there are no simple tropes. In this paper, we provide a response to Ehring defending the standard view. Ehring’s argument may be refuted by (1) distinguishing the ontological form of tropes from their contribution to the ontological content of the world, and (2) construing tropes as having primitive identity. At the same (...) time, standard trope nominalism is elaborated on by distinguishing between ontological form and content, for which there are also independent reasons. (shrink)

The standard philosophical analysis of counterfactual conditionals—the Lewis-Stalnaker analysis—analyzes the truth-conditions of counterfactuals in terms of nearby possible worlds. This paper demonstrates that this analysis is false. §1 shows that it is a serious epistemic and metaphysical possibility that our “world” is a massive computer simulation, and that if the Lewis-Stalnaker analysis of counterfactuals is correct, then it should extend seamlessly to the case that our world is a computer simulation, in the form of a possible-simulation semantics. §2 then shows, (...) however, that a Lewis-Stalnaker-style possible-simulation semantics clearly fails as an analysis of the truth-conditions of counterfactuals in two types of simulated worlds: Humean Simulations and Necessitarian simulations. §3 then considers and answers several objections to the argument. Finally, §4 draws several skeptical, but compelling lessons about counterfactuals from the argument. (shrink)

This paper assesses the role of the Refutation of Idealism within the Critique of Pure Reason, as well as its relation to the treatment of idealism in the First Edition and to transcendental idealism more generally. It is argued that the Refutation is consistent with the Fourth Paralogism and that it can be considered as an extension of the Transcendental Deduction. While the Deduction, considered on its own, constitutes a 'regressive argument', the Refutation allows us to turn (...) the Transcendental Analytic into a 'progressive argument' that proceeds by the synthetic method.
