In this paper, I argue that arguments from expert opinion, i.e., inferences from “Expert E says that p” to “p,” where the truth value of p is unknown, are weak arguments. A weak argument is an argument in which the premises, even if true, provide weak support—or no support at all—for the conclusion. Such arguments from expert opinion are weak arguments unless the fact that an expert says that p makes p significantly (...) more likely to be true. However, research on expertise shows that expert opinions are only slightly more accurate than chance and much less accurate than decision procedures. If this is correct, then it follows that arguments from expert opinion are weak arguments. (shrink)

In this paper, I reply to Seidel’s objections against my argument from expert performance to the effect that arguments from expert opinion are weak arguments. I clarify what Seidel takes to be unclear points in my argument and show that it withstands Seidel’s objections.

In this paper it is shown how plausible reasoning of the kind illustrated in the ancient Greek example of the weak and strong man can be analyzed and evaluated using a procedure in which the pro evidence is weighed against the con evidence using formal, computational argumentation tools. It is shown by means of this famous example how plausible reasoning is based on an audience’s recognition of situations of a type they are familiar with as normal and comprehensible in (...) their shared common knowledge. The paper extends previous work on this example by using three new multiagent argumentation schemes closely related to the scheme for argument from negative consequences. (shrink)

Quine's views on indispensability arguments in mathematics are scrutinised. A weak indispensability argument is distinguished from a strong indispensability thesis. The weak argument is the combination of the criterion of ontological commitment, holism and a mild naturalism. It is used to refute nominalism. Quine's strong indispensability thesis claims that one should consider all and only the mathematical entities that are really indispensable. Quine has little support for this thesis. This is even clearer if one takes into account (...) Maddy's critique of Quine's strong indispensability thesis. Maddy's critique does not refute Quine's weak indispensability argument. We are left with a weak and almost unassailable indispensability argument. (shrink)

The design argument for God’s existence was critically assessed when in the growth of modern science the cognitive value of teleological categories was called into question. In recent discussions dealing with anthropic principles there has appeared a new version of the design argument, in which cosmic design is described without the use of teleological terms. The weak anthropic principle (WAP), a most critical version of all these principles, describes the fine-tuning of physical parameters necessary to the genesis of carbon-based (...) life. Consequently, a new version of the philosophical design argument can be developed on the basis of the weak anthropic principle.(edited). (shrink)

The contemporary Platonists in the philosophy of mathematics argue that mathematical objects exist. One of the arguments by which they support this standpoint is the so-called Enhanced Indispensability Argument (EIA). This paper aims at pointing out the difficulties inherent to the EIA. The first is contained in the vague formulation of the Argument, which is the reason why not even an approximate scope of the set objects whose existence is stated by the Argument can be established. The second problem (...) is reflected in the vagueness of the very term indispensability, which is essential to the Argument. The paper will remind of a recent definition of the concept of indispensability of a mathematical object, reveal its deficiency and propose an improvement of this definition. Following this, we will deal with one of the consequences of the arbitrary employment of the concept of indispensability of a mathematical theory. We will propose a definition of this concept as well, in accordance with the common intuition about it. Eventually, on the basis of these two definitions, the paper will describe the relation between these two concepts, in the attempt to clarify the conceptual apparatus of the EIA. (shrink)

This paper proposes a novel relational view of autonomy designed to overcome the inadequacies of procedural and substantive views of autonomy as they relate to physician-assisted suicide requests for individuals with diminished cognitive functioning. Traditional and other relational views of autonomy regard a patient as an “isolated monad,” ignore patients with limited personal autonomy, and overlook the contexts in which decisions like PAS are made. However, these weaknesses become the strengths of a synthesized relational view of autonomy, which enhances the (...) personal autonomy of those with limited personal autonomy so that their PAS requests can be granted.

In the literature, regress arguments often take one of two different forms: either they conclude that a given solution fails to solve any problem of a certain kind (the strong conclusion), or they conclude that a given solution fails to solve all problems of a certain kind (the weaker conclusion). This gives rise to a logical problem: do regresses entail the strong or the weaker conclusion, or none? In this paper I demonstrate that regress arguments can in fact (...) take both forms, and clearly set out the logical difference between them. Throughout the paper, I confine myself to metaphysical examples from the early Russell. Only now that we know they are valid can we start to discuss whether they are sound. (shrink)

Let it be granted that Buddhism has, e.g., in its logical literature, detailed canons and explicit rules of right reason that, amongst other things, ban inconsistency as irrational. This is the normative dimension of how people should think according to many major Buddhist authors. But do important Buddhist writers ever recognize any interesting or substantive role for inconsistency and forms of irrationality in their account of how people actually do think and act? The article takes as its point of departure (...) a recurring theme in the writings of the 8th Century Indian Buddhist thinker, Śāntideva, who subjects his own behaviour and thought to minute scrutiny in argumentation with himself, only to be puzzled at his own seemingly irrational persistence in ways of thinking that he knows to be wrong and actions that he knows to be worse courses. The Buddhist’s situation is profitably comparable to issues of akrasia, weakness of the will, that are taken up by Plato, Aristotle and many modern philosophers, including notably Donald Davidson and David Wiggins.

Hare proposes a view he calls prospectism for making choices in situations in which preferences have a common, but problematic structure. I show that prospectism permits the decision-maker to make a series of choices she knows in advance will lead to a sure loss. I also argue that a theory that permits the decision-maker to make choices she knows in advance will lead to a sure loss should be rejected.

Context: Is non-dualist epistemology, based on the unity of descriptions and objects, logically consistent? Problem: What is the status of the infinite regresses that the non-dualist Josef Mitterer, in his book The Beyond of Philosophy, censures in dualist thought? Their academic discussion is still in its infancy. Method: An attempt to reconstruct and differentiate Mitterer’s infinite regress accusations against dualism (originating from the 1970s) with today’s means and distinctions. Results: A weak and a strong linguistic principle are presented (non-dualism (...) being subsumed under the strong linguistic principle), which are defined as such depending on whether the infinite regresses of dualism are interpreted as benign or as vicious. Implications: Further penetrating investigation of the infinite regresses highlighted by Mitterer is of crucial importance because these regresses have not yet been discussed and classified in relevant current publications on infinite regress arguments by authors such as Rescher or Gratton. Such proper classification is indispensable, however, if the value of the non-dualist alternative to, and its critique of, dualist thought is to be assessed adequately. (shrink)

In 2020, Daniele Molinini published a paper outlining two types of mathematical objectivity. One could say that with this paper Molinini not only separated two mathematical concepts in terms of terminology and content, but also contrasted two mathematical-philosophical contexts, the traditional-idealistic and the modern-practical. Since the first context was the theoretical basis for a large number of analyses that we find in the framework of the philosophy of mathematics, the space was now offered to re-examine such analyses in the second (...) context. More specifically, with respect to the second context, we will analyse the strength of one of the few explicit Platonic arguments that seeks to justify the ontological status of mathematical objects and the central claim of mathematical Platonism about the existence of mathematical objects.

Saunders' recent arguments in favour of the weak discernibility of (certain) quantum particles seem to be grounded in the 'generalist' view that science only provides general descriptions of the worlIn this paper, I introduce the ‘generalist’ perspective and consider its possible justification and philosophical basis; and then look at the notion of weak discernibility. I expand on the criticisms formulated by Hawley (2006) and Dieks and Veerstegh (2008) and explain what I take to be the basic problem: (...) that the properties invoked by Saunders cannot be pointed to as ‘individuators’ of otherwise indiscernible (and thus numerically identical) entities because their ontological status remains underdetermined by the evidence and the established interpretation of the theory. In addition to to this, I suggest that Saunders does not deal adequately with bosons, and cannot do so exactly because he subscribes to PII and the generalist picture. The last part of the paper contains a critical examination of the claim (or at least implicit assumption) that the generalist picture should be regarded as obviously compelling by the modern-day empiricist.

Some authors have argued that, in order to give an account of weakness of the will, we must assume that the mind is divisible into parts. This claim is often referred to as the partitioning claim. There appear to be two main arguments for this claim. While the first is conceptual and claims that the notion of divisibility is entailed by the notion of non-rational mental causation (which is held to be a necessary condition of weakness of the will), (...) the second is explanatory and claims that the notion of divisibility is required for the causal explanation of weak-willed action. In this paper I want to argue that the partitioning claim remains unsupported, no matter how it is interpreted, and that weakness of the will can be made perfectly good sense of without the idea that the mind is divisible into parts. In fact, there are available various explanatory models each of which characterizes different psychological mechanisms that may be involved in weakness of will, none of which depends on any claims about mental division. I describe three familiar mechanisms and argue that weakness of will may occur as the result of any one of them. (shrink)

Can there be a state which is both a belief and a desire? More exactly, a state which is a belief that p and a desire that q, where p and q may be the same proposition or a different one? Such a state would be a ‘besire’. So a first question is the general question whether besires are possible. Normative attitudes would be good candidates for besires. For example, if Sandra has the normative attitude that it would be best (...) for her to leave the country, this seems to be a propositional state of hers which may be both a belief and a desire. Or, for another example, suppose that Michael has the normative attitude that one should not lie without good reason. Then he seems to hold a belief about lying, namely, that lying without good reason is normatively forbidden, and, at the same time, he also seems to have a desire with respect to lying, namely, the desire not to lie without good reason. A second question is whether normative attitudes are besires.1 There are other good candidates for besires. A ‘simple’ state like the state of the young chicken expressed by its cry may be a case in point. Even though the chicken’s state is probably not a full-blooded propositional state, it seems to be ‘Janus-faced’ as well. Does it descriptively represent the chicken’s hunger? Or is it a desire for food? Maybe both – and then it could be a besire, or something like that.2 Ruth Garrett Millikan mentions another candidate, namely, intentions. Intentions clearly have a desire-like nature. And arguably, they.. (shrink)

This study investigated whether perspective-taking reduces belief bias independently of argument strength. Belief bias occurs when individuals evaluate belief-consistent arguments more favourably than belief-inconsistent arguments. Undergraduates read arguments that varied with respect to belief-consistency and strength about the topic of climate change. After participants read each argument, those in the perspective-taking condition rated the argument's strength from a perspective of a climate scientist and then from their own perspectives, whereas those in the no perspective-taking condition only rated (...) the arguments from their own perspectives. Perspective-taking eliminated belief bias for weak arguments, but not for strong arguments. Theoretical and practical implications of the results are discussed, and directions for future research are provided. (shrink)

Some generic sentences seem to be true despite the fact that almost all the members of the relevant kind are exceptions. It’s controversial whether generics of this type express relatively weak generalizations or relatively strong ones. If the latter, then we’re systematically mistaken about their truth, but they make no trouble for our semantic theorizing. In this brief note, I present several arguments for the former: sentences of the relevant type are weak generics.

Strong reciprocity theorists claim that punishment has evolved to promote the good of the group and to deter cheating. By contrast, weak reciprocity suggests that punishment aims to restore justice (i.e., reciprocity) between the criminal and his victim. Experimental evidences as well as field observations suggest that humans punish criminals to restore fairness rather than to support group cooperation.

First aim of this paper is to show that Evidentialism, when paired with a Psychologistic ontology of evidence, is unable to account for ordinary cases of inferential justification. As many epistemologists have maintained, however, when it is paired with a Propositionalist ontology of evidence, Evidentialism is unable to explain in a satisfactory way ordinary cases of perceptual justification. So, the Evidentialist is faced with a dilemma. Second aim of this paper is to give an argument in favour of Propositionalism about (...) evidence, and so to motivate the conclusion that perceptual justification must be accounted for in non-evidentialist terms. By this I do not mean to defend a strongly Non-Evidentialist epistemology, according to which there are doxastic attitudes which are unsupported by any justifier. More modestly, I aim to motivate the weakly Non-Evidentialist epistemology according to which a subject’s perceptual beliefs may be justified by non-evidential justifiers. I conclude the paper by explaining why I believe that Pryor's dogmatism supplies a model for the way in which an internalist who is persuaded by my argument might want to detail her weakly Non-Evidentialist account of perceptual justification.

Very broadly, an argument from collections is an argument that purports to show that our beliefs about sets imply — in some sense — the existence of God. Plantinga (2007) first sketched such an argument in “Two Dozen” and filled it out somewhat in his 2011 monograph Where the Conflict Really Lies: Religion, Science, and Naturalism. In this paper I reconstruct what strikes me as the most plausible version of Plantinga’s argument. While it is a good argument in at least (...) a fairly weak sense, it doesn’t initially appear to have any explanatory advantages over a non-theistic understanding of sets — what I call set theoretic realism. However, I go on to argue that the theist can avoid an important dilemma faced by the realist and, hence, that Plantinga’s argument from collections has explanatory advantages that realism does not have.

Weak links, in the form of inadequacies in both reasoning and supporting evidence, exist at several critical steps in the derivation of an hierarchical concept of evolution from punctuated equilibria. Punctuation itself is predicated on a distorted reading of phyletic change as phyletic gradualism, and of allopatric speciation as the instantaneous formation of unchanging typological taxa. The concept of punctuation is further confounded by the indescriminate employment of the same term to denote both a causal explanation for evolutionary change (...) and an outcome of substantiated evolutionary processes. Even when the intended usage for the term is specified, each denotation of punctuation entails respective drawbacks. As a causal explanation, punctuation clearly belongs to the class of quantum theories with all their attendant impedimenta, including special salsatory non-adaptive mechanisms of evolutionary change. Redefinition of punctuation as a pattern of morphologic change reduces it to one possible outcome of known microevolutioanry processes, thus obviating any need for an hierarchical explanation of macroevolution. While vacillation between usages has preserved the term in the literature, the end result of this obfuscation has been a circle of faulty reasoning in which the pattern of punctuation is invoked as its own proof. Widespread confusion concerning what constitutes an adequate test of punctuation is directly attributable to imprecision in both the original and revised formulations of the concept.The argument for species-level selection is based on the typological and philosphically flawed premise of species as individuals, and further requires the hypothesis of heritable emergent properties, for which empirical evidence is lacking.

Weakly Aggregative Modal Logic (WAML) is a collection of disguised polyadic modal logics with n-ary modalities whose arguments are all the same. WAML has some interesting applications on epistemic logic and logic of games, so we study some basic model theoretical aspects of WAML in this paper. Specifically, we give a van Benthem-Rosen characterization theorem of WAML based on an intuitive notion of bisimulation and show that each basic WAML system Kn lacks Craig Interpolation.

High-quality arguments have strong and lasting persuasive effects, suggesting that people can distinguish high- from low-quality arguments. However, we know little of what norms people employ to make that distinction. Some studies have shown that, in evaluating arguments from consequences, people are more sensitive to differences with respect to the desirability of these consequences than to differences in the likelihood that these consequences will occur. This raises the question of whether people lack the criteria to distinguish high-quality (...) from low-quality arguments in support of such claims. In an experiment, 196 participants without any training in argument theory rated their acceptance of 30 claims about the likelihood that a certain outcome would result from a certain action. These claims were supported by an argument from authority, or from cause to effect, or from example. Arguments were systematically manipulated to violate nine specific criteria. For seven out of the nine criteria violation decreased acceptance of the claim supported. These findings show that people can use argument type specific criteria to distinguish high- from low-quality arguments. (shrink)

Blackshaw and Hendricks have recently developed and defended the impairment argument against abortion, arguing that the immorality of giving a child fetal alcohol syndrome (FAS) provides us with reason to believe that abortion is immoral.

Second, we argue that Blackshaw and Hendricks are fundamentally mistaken about what makes giving a child FAS (...) immoral. Once we acknowledge this, it is clear that our intuitions about giving a child FAS provide no support for the supposed immorality of abortion. (shrink)

Muller and Saunders ([2008]) purport to demonstrate that, surprisingly, bosons and fermions are discernible; this article disputes their arguments, then derives a similar conclusion in a more satisfactory fashion. After briefly explicating their proof and indicating how it escapes earlier indiscernibility results, we note that the observables which Muller and Saunders argue discern particles are (i) non-symmetric in the case of bosons and (ii) trivial multiples of the identity in the case of fermions. Both problems undermine the claim that (...) they have shown particles to be physically discernible. We then prove two results concerning observables that are truly physical: one showing when particles are discernible and one showing when they are not (categorically) discernible.

Kim argues that weak and global supervenience are too weak to guarantee any sort of dependency. Of the three original forms of supervenience, strong, weak, and global, each commonly wielded across all branches of philosophy, two are thus cast aside as uninteresting or useless. His arguments, however, fail to appreciate the strength of weak and global supervenience. I investigate what weak and global supervenience relations are functionally and how they relate to strong supervenience. For (...) a large class of properties, weak and global supervenience are equivalent to strong supervenience. I then offer a series of arguments showing that it is precisely because of their strength, not their weakness, that both weak and global supervenience are useless in characterizing any dependencies of interest to philosophers.

The transformers that drive chatbots and other AI systems constitute large language models (LLMs). These are currently the focus of a lively discussion in both the scientific literature and the popular media. This discussion ranges from hyperbolic claims that attribute general intelligence and sentience to LLMs, to the skeptical view that these devices are no more than “stochastic parrots”. I present an overview of some of the weak arguments that have been presented against LLMs, and I consider several (...) of the more compelling criticisms of these devices. The former significantly underestimate the capacity of transformers to achieve subtle inductive inferences required for high levels of performance on complex, cognitively significant tasks. In some instances, these arguments misconstrue the nature of deep learning. The latter criticisms identify significant limitations in the way in which transformers learn and represent patterns in data. They also point out important differences between the procedures through which deep neural networks and humans acquire knowledge of natural language. It is necessary to look carefully at both sets of arguments in order to achieve a balanced assessment of the potential and the limitations of LLMs. (shrink)

The paper analyzes the philosophical consequences of the recent discovery of direct violations of the time–reversal symmetry of weak interactions. It shows that although we have here an important case of the time asymmetry of one of the fundamental physical forces which could have had a great impact on the form of our world with an excess of matter over antimatter, this asymmetry cannot be treated as the asymmetry of time itself but rather as an asymmetry of some specific (...) physical process in time. The paper also analyzes the consequences of the new discovery for the general problem of the possible connections between direction of time and time-asymmetric laws of nature. These problems are analyzed in the context of Horwich’s Asymmetries in time: problems in the philosophy of science argumentation, trying to show that existence of a time–asymmetric law of nature is a sufficient condition for time to be anisotropic. Instead of Horwich’s sufficient condition for anisotropy of time, it is stressed that for a theory of asymmetry of time to be acceptable it should explain all fundamental time asymmetries: the asymmetry of traces, the asymmetry of causation, and the asymmetry between the fixed past and open future. It is so because the problem of the direction of time has originated from our attempts to understand these asymmetries and every plausible theory of the direction of time should explain them.

This chapter focuses on one of the common fallacies in Western philosophy called ' weak analogy'. As Patrick Hurley writes, the weak analogy fallacy “occurs when the conditions of an argument depend on an analogy (or similarity) that is not strong enough to support the conclusion”. Often, vegetarians and vegans will hear the following argument from analogy in defense of carnivorism: “Animals eat each other in nature, so it's permissible for us to eat them as well”. By focusing (...) on the similarities between animals and humans, and by arguing that these similarities are indeed relevant to the issue at hand, philosopher Peter Singer presents a strong argument from analogy in favor of the conclusion that animals are indeed sentient beings.

Recent work has argued that belief is weak: the level of rational credence required for belief is relatively low. That literature has contrasted belief with assertion, arguing that the latter requires an epistemic state much stronger than (weak) belief---perhaps knowledge or even certainty. We argue that this is wrong: assertion is just as weak as belief. We first present a variety of new arguments for this, and then show that the standard arguments for stronger norms (...) are not convincing. Finally, we sketch an alternative picture on which the fundamental norm of assertion is to say what you believe, but both belief and assertion are weak. To help make sense of this, we propose that both belief and assertion involve navigating a tradeoff between accuracy and informativity, and so it can makes sense to believe/say something you only have weak evidence for, if it is informative enough.

There are well-known quasi-formal arguments that identity is a "strict" relation in at least the following three senses: (1) There is a single identity relation and a single distinctness relation; (2) There are no contingent cases of identity or distinctness; and (3) There are no vague or indeterminate cases of identity or distinctness. However, the situation is less clear cut than it at first may appear. There is a natural formal theory of identity that is very close to the (...) standard classical theory but which does not validate the formal analogues of (1)-(3). The core idea is simple: We weaken the Principle of the Indiscernibility of Identicals from a conditional to an entailment and we adopt a weakly classical logic. This paper investigates this weakly classical theory of identity (and related theories) and discusses its philosophical ramifications. It argues that we can accept a reasonable theory of identity without committing ourselves to the uniqueness, necessity, or determinacy of identity. (shrink)

Transhumanism aims to bring about radical human enhancement. In ‘Truly Human Enhancement’ Agar (2014) provides a strong argument against producing radically enhancing effects in agents. This leaves the transhumanist in a quandary—how to achieve radical enhancement whilst avoiding the problem of radically enhancing effects? This paper aims to show that transhumanism can overcome the worries of radically enhancing effects by instead pursuing radical human enhancement via incremental moderate human enhancements (Weak Transhumanism). In this sense, weak transhumanism is much (...) like traditional transhumanism in its aims, but starkly different in its execution. This version of transhumanism is weaker given the limitations brought about by having to avoid radically enhancing effects. I consider numerous objections to weak transhumanism and conclude that the account survives each one. This paper’s proposal of ‘weak transhumanism’ has the upshot of providing a way out of the ‘problem of radically enhancing effects’ for the transhumanist, but this comes at a cost—the restrictive process involved in applying multiple moderate enhancements in order to achieve radical enhancement will most likely be dissatisfying for the transhumanist, however, it is, I contend, the best option available.

Professional environmental ethics arose directly out of the interest in the environment created by Earth Day in 1970. At that time many environmentalists, primarily because they had read Aldo Leopold’s essay, “The Land Ethic,” were convinced that the foundations of environmental problems were philosophical. Moreover, these environmentalists were dissatisfied with the instrumental arguments based on human use and benefit—which they felt compelled to invoke in defense of nature—because they thought these arguments were part of the problem. Wanting to (...) counter instrumental arguments in some way with non- or even anti-instrumental arguments, and unable to think of anything else to say, they began wistfully suggesting that perhaps nature had or ought to have rights. When professional environmental ethics came into its own in the early 1980s, rights for nature were one of the first subjects to be debated in detail. Unfortunately, however, no one could come up with a theory to support such rights attributions. Nevertheless, because rights had been invoked by environmentalists to challenge the preeminent role of instrumental value arguments, and because the field of environmental ethics developed in support of environmental concerns and arguments, environmental ethicists turned to an examination of noninstrumental or intrinsic value arguments for the preservation of nature.

The article deals with Habermas's intersubjective approach to critical social theory, focusing on his intersubjective accounts of truth, justice and democratic legitimacy. Distinguishing between stronger and weaker versions of an intersubjective account, it draws attention to Habermas's recent move from a strong intersubjective, constructivist, interpretation of truth to a weaker, non-constructivist, one. It then looks at his refusal to make a similar move in the case of justice, arguing that it is not well-founded, even from the point of view of (...) Habermas's overall concerns. It contends, in particular, that a strong intersubjective conception is not necessary in order to maintain the close link between normative validity and argumentation that plays an important role in Habermas's project of a critical social theory and concludes that the advantages of abandoning a strong intersubjective position outweigh the disadvantages. Consequently, it recommends extension of the weaker, non-constructivist, account that Habermas now proposes in the case of truth to justice as well. In the final section, it considers the implications of this recommendation for Habermas's conception of normative validity in the domain of law and politics. (shrink)

After briefly considering Plato’s objections to rhetoric—it disregards the truth, aiming only to persuade, and it manipulates our emotions rather than instructing us—I turn to the historical Gorgias. The ‘Encomium of Helen’ ascribes to logos virtually all-powerful capacities for persuasion, seduction, and even bewitchment. Here Gorgias celebrates the very things Plato rejects. Yet in the ‘Defense of Palamedes’ considerable anxieties about whether logos actually does possess such strength are voiced: the weakness, not the power, of logos comes to occupy center (...) stage. Gorgias’ own views thus are likely more complex than Plato allows. (shrink)

For n<ω, we say that theΠn1-reflection principle holds at κ and write Refln if and only if κ is a Πn1-indescribable cardinal and every Πn1-indescribable subset of κ has a Πn1-indescribable proper initial segment. The Πn1-reflection principle Refln generalizes a certain stationary reflection principle and implies that κ is Πn1-indescribable of order ω. We define a forcing which shows that the converse of this implication can be false in the case n=1; that is, we show that κ being Π11-indescribable of (...) order ω need not imply Refl1. Moreover, we prove that if κ is -weakly compact where α<κ+, then there is a forcing extension in which there is a weakly compact set W⊆κ having no weakly compact proper initial segment, the class of weakly compact cardinals is preserved and κ remains -weakly compact. We also formulate several open problems and highlight places in which standard arguments seem to break down. (shrink)

This paper is my best attempt to confute (Kantian) Modern Philosophy at its very core. This implies, of course, that in my view the principles of Critical Realism are Kantian.

Section 3 on the principle of immanence offers the most important contribution in this undertaking. The arguments of critical realism studied in this paper are (...) the following: 1. The Notion of Experience 2. The Nature of Knowledge: Question and Inquiry 3. The Principle of Immanence 4. The Notion of Relation 5. Judgment as the Position of the Real. (shrink)

The unconditional version of motivational internalism says that if an agent sincerely judges that to φ in circumstances C is the best option available to her, then, as a matter of conceptual necessity, she will be motivated to φ in C. This position faces a powerful counterargument according to which it is possible for various cases of practical irrationality to completely defeat an agent’s moral motivation while, at the same time, leaving her appreciation of her moral reasons intact. In this (...) paper, I will argue that weakness of will, as the paradigmatic case of practical irrationality, and all other cases of practical irrationality that feature in standard formulations of this argument do not represent genuine counterexamples to this version of motivational internalism. In this sense, the main aim of this paper is to show that proponents of this internalist position are well justified in their denial of the claim that there are people who are completely unmotivated by their judgments about what is the best option available to them.

This paper offers the first moral defense of markets in votes in a democratic electoral system based on majority rule where there are no moral restrictions on how votes can be cast. In Part 1 I outline the type of vote buying that I defend in this paper, and defend my methodological assumption. In Part 2 I criticize Freiman’s arguments for legalizing vote buying. In Part 3 I outline and reply to some responses that could be made to my (...) criticisms of Freiman’s arguments. In Part 4 I draw from the flaws in Freiman’s arguments to argue that vote buying is morally permissible and defend these arguments against objections. (shrink)

Adhering to the traditional concept of omniscience lands Gale in the incoherence Grim’s Cantorian arguments reveal in talk of “all propositions.” By constructing variants and extensions of Grim’s arguments, I explain why various ways out of the incoherence are unacceptable, why theists would do better to adopt a certain revisionary concept of omniscience, and why the Cantorian troubles are so deep as to be troubles as well for Gale’s Weak PSR. I conclude with some brief reflections on (...) method, suggesting that we pursue the full implications of Gale’s own revisionary remarks and replace his method of analytic argumentation with non-analytic revisionary theory-construction.
