In this paper I investigate, within the framework of realistic interpretations of the wave function in nonrelativistic quantum mechanics, the mathematical and physical nature of the wave function. I argue against the view that mathematically the wave function is a two-component scalar field on configuration space. First, I review how this view makes quantum mechanics non- Galilei invariant and yields the wrong classical limit. Moreover, I argue that interpreting the wave function as a ray, in agreement many physicists, Galilei invariance (...) is preserved. In addition, I discuss how the wave function behaves more similarly to a gauge potential than to a field. Finally I show how this favors a nomological rather than an ontological view of the wave function. (shrink)

Much of the discussion surrounding the ethics of abortion has centered around the notion of personhood. This is because many philosophers hold that the morality of abortion is contingent on whether the fetus is a person - though, of course, some famous philosophers have rejected this thesis (e.g. Judith Thomson and Don Marquis). In this article, I construct a novel argument for the immorality of abortion based on the notion of impairment. This argument does not assume that the (...) fetus is a person - indeed, I concede (for the sake of argument) that the fetus is not a person - and hence the morality of abortion is not contingent on whether the fetus is a person. I finish by answering a plethora of objections to my argument, concluding that none of them are successful. (shrink)

Andy Clark and David Chalmers (1998) argue that certain mental states and processes can be partially constituted by objects located beyond one’s brain and body: this is their extended mind thesis (EM). But they maintain that consciousness relies on processing that is too high in speed and bandwidth to be realized outside the body (see Chalmers, 2008, and Clark, 2009). I evaluate Clark’s and Chalmers’ reason for denying that consciousness extends while still supporting unconscious state extension. I argue that their (...) reason is not well grounded and does not hold up against foreseeable advances in technology. I conclude that their current position needs re-evaluation. If their original parity argument works as a defence of EM, they have yet to identify a good reason why it does not also work as a defence of extended consciousness. I end by advancing a parity argument for extended consciousness and consider some possible replies. (shrink)

We offer a critical assessment of the “exclusion argument” against free will, which may be summarized by the slogan: “My brain made me do it, therefore I couldn't have been free”. While the exclusion argument has received much attention in debates about mental causation (“could my mental states ever cause my actions?”), it is seldom discussed in relation to free will. However, the argument informally underlies many neuroscientific discussions of free will, especially the claim that advances in (...) neuroscience seriously challenge our belief in free will. We introduce two distinct versions of the argument, discuss several unsuccessful responses to it, and then present our preferred response. This involves showing that a key premise – the “exclusion principle” – is false under what we take to be the most natural account of causation in the context of agency: the difference-making account. We finally revisit the debate about neuroscience and free will. (shrink)

This paper presents a moral argument in support of the view that the mind is a nonphysical object. It is intuitively obvious that we, the bearers of conscious experiences, have an inherent value that is not reducible to the value of our conscious experiences. It remains intuitively obvious that we have inherent value even when we represent ourselves to have no physical bodies whatsoever. Given certain assumptions about morality and moral intuitions, this implies that the bearers of conscious experiences—the (...) objects possessing inherent value—are not physical objects. This moral evidence is corroborated by introspective evidence. (shrink)

Truthmaker necessitarianism is the view that an object is a truthmaker for a truth-bearer only if it is impossible for the object to exist and the truth-bearer be false. While this thesis is widely regarded as truthmaking "orthodoxy", it is rarely explicitly defended. In this paper I offer an argument in favor of necessitarianism that raises the question of what the truthmakers are for the truths about truthmaking. The supposed advantages of non-necessitarianism dissolve once we take these truths into (...) account. (shrink)

In this paper, I argue that Islamic theism is best explained by the hypothesis of Divine Commission, whereby Muhammad is viewed as being divinely commissioned to serve the overall salvific purposes of God. To this end, I present three observation reports relating to Islamic theism and evaluate HDC against an alternative hypothesis, the hypothesis of Non-Commission whereby Muhammad is not viewed as being divinely commissioned. I argue that the probability of the observation reports is greater on the assumption that HDC (...) is true than on the assumption that NC is true. Accordingly, this gives us reason to prefer HDC as a better explanation of Islamic theism. (shrink)

Konserwatywni przeciwnicy prowadzenia badań naukowych na ludzkich embrionach argumentują, że od momentu poczęcia mają one status moralny równy statusowi ludzi dorosłych: zarodki mają takie samo prawo do życia jak dorośli. W artykule przedstawiam oryginalną argumentację za tym stanowiskiem, której źródła można znaleźć w XVII-wiecznej teologii moralnej i współczesnej teorii decyzji. Argumentacja ta nie odwołuje się do statusu ontologicznego embrionów, ale do pewnego typu rozumowania praktycznego na temat tego, co należy robić w rozmaitych sytuacjach niepewności. Na pierwszy rzut oka wydaje się (...) ona wzmacniać stanowisko konserwatywne, ponieważ nie zależy od kontrowersyjnych metafizycznych założeń na temat statusu zarodków czy kwestii ich potencjalności.

A new formulation of the Fine-Tuning Argument (FTA) for the existence of God is offered, which avoids a number of commonly raised objections. I argue that we can and should focus on the fundamental constants and initial conditions of the universe, and show how physics itself provides the probabilities that are needed by the argument. I explain how this formulation avoids a number of common objections, specifically the possibility of deeper physical laws, the multiverse, normalisability, whether God would (...) fine-tune at all, whether the universe is too fine-tuned, and whether the likelihood of God creating a life-permitting universe is inscrutable.

In my article "Even if the fetus is not a person, abortion is immoral: The impairment argument" (this journal), I defended what I called “The impairment argument” which purports to show that abortion is immoral. Bruce Blackshaw (2019) has argued that my argument fails on three accounts. In this article, I respond to his criticisms.

Derk Pereboom's Four-Case Argument is among the most famous and resilient manipulation arguments against compatibilism. I contend that its resilience is not a function of the argument's soundness but, rather, the ill-gotten gain from an ambiguity in the description of the causal relations found in the argument's foundational case. I expose this crucial ambiguity and suggest that a dilemma faces anyone hoping to resolve it. After a thorough search for an interpretation which avoids both horns of this (...) dilemma, I conclude that none is available. Rather, every metaphysically coherent interpretation invites either a hard- or soft-line reply to Pereboom's argument. I then consider a recharacterization of the dilemma which seems to clear the way for the defence of a revised Four-Case Argument. I address this rejoinder by identifying a still more fundamental problem shared by all viable interpretations of the manipulation cases, showing that each involves a type of manipulation which undermines the victim's agency. Because this diagnosis supports a soft-line reply to every viable interpretation of the argument and can be endorsed by any compatibilist, I consider it the final piece of the Soft-line Solution to the Four-Case Argument. Finally, I suggest a new taxonomy of manipulation arguments, arguing that none that employs the suppressive variety of manipulation found in Pereboom's argument offers a threat to compatibilism.

The compatibility of determinism and the ability to do otherwise has been implicitly assumed by many to be irrelevant to the viability of compatibilist responses to the manipulation argument for incompatibilism. I argue that this assumption is mistaken. The manipulation argument may be unsound. But even so, the manipulation argument, at the very least, undermines classical compatibilism, the view that free will requires the ability to do otherwise, and having that ability is compatible with determinism. This is (...) because classical compatibilism, in conjunction with any type of reply to the manipulation argument, has counterintuitive implications. In order to avoid such implications, we need not hold that determinism is incompatible with moral responsibility. But we must hold that determinism is incompatible with the ability to do otherwise.

In this paper, I critically discuss one of the more influential arguments for mereological universalism, what I will call ‘the Vagueness Argument’. I argue that a premise of the Vagueness Argument is not well supported and that there are at least two good reasons for thinking that the premise in question is false.

This article explores the relationship between epistemic relativism and Pyrrhonian scepticism. It is argued that a fundamental argument for contemporary epistemic relativism derives from the Pyrrhonian problem of the criterion. Pyrrhonian scepticism is compared and contrasted with Cartesian scepticism about the external world and Humean scepticism about induction. Epistemic relativism is characterized as relativism due to the variation of epistemic norms, and is contrasted with other forms of cognitive relativism, such as truth relativism, conceptual relativism and ontological relativism. An (...) argument from the Pyrrhonian problem of the criterion to epistemic relativism is presented, and is contrasted with three other arguments for epistemic relativism. It is argued that the argument from the criterion is the most fundamental argument for epistemic relativism. Finally, it is noted how the argument of the present paper fits with the author’s previous suggestion that a particularist response to the Pyrrhonian sceptic may be combined with a naturalistic view of epistemic warrant to meet the challenge of epistemic relativism.

In this paper I argue that the explanationist argument in favour of moral realism fails. According to this argument, the ability of putative moral properties to feature in good explanations provides strong evidence for, or entails, the metaphysical claims of moral realism. Some have rejected this argument by denying that moral explanations are ever good explanations. My criticism is different. I argue that even if we accept that moral explanations are (sometimes) good explanations the metaphysical claims of (...) realism do not follow. (shrink)

I propose a new reading of Hegel’s discussion of modality in the ‘Actuality’ chapter of the Science of Logic. On this reading, the main purpose of the chapter is a critical engagement with Spinoza’s modal metaphysics. Hegel first reconstructs a rationalist line of thought — corresponding to the cosmological argument for the existence of God — that ultimately leads to Spinozist necessitarianism. He then presents a reductio argument against necessitarianism, contending that as a consequence of necessitarianism, no adequate (...) explanatory accounts of facts about finite reality can be given.

In his Pyrrhonian Outlines , Sextus Empiricus employs an argument based upon the possibility of disagreement in order to show that one should not assent to a Dogmatic claim to which at present one cannot oppose a rival claim. The use of this argument seems to be at variance with the Pyrrhonian stance, both because it does not seem to accord with the definition of Skepticism and because the argument appears to entail that the search for truth (...) is doomed to failure. In the present paper, I examine the passages in which Sextus utilizes the argument from possible disagreement and offer an interpretation that makes the use of this argument compatible with the Pyrrhonian outlook.

This paper offers a short extension of the dialogue between Anselm and the Fool that is contained in "The Ontological Argument Simplified" by Gary Matthews and Lynne Rudder Baker. My extension of the dialogue ends with the Fool proclaiming that "what looks like an argument of elegant simplicity turns out to be no argument at all".

Discussion on whether Hume's treatment of induction is descriptive or normative has usually centred on Hume's negative argument, somewhat neglecting the positive argument. In this paper, I will buck this trend, focusing on the positive argument. First, I argue that Hume's positive and negative arguments should be read as addressing the same issues . I then argue that Hume's positive argument in the Enquiry is normative in nature; drawing on his discussion of scepticism in Section 12 (...) of the Enquiry, I explain a framework by which he provides what I call consequent justification for our inductive practices in his positive argument. Based on this, I argue that his negative argument in the Enquiry should similarly be read as normative in nature. (shrink)

Perszyk has argued that Molinists cannot consistently endorse the consequence argument because of a structurally similar argument for the incompatibility of true Molinist counterfactuals of freedom and the ability to do otherwise. Wierenga has argued that on the proper understanding of CCFs, there is a relevant difference between the consequence argument and the anti-Molinist argument. I argue that, even on Wierenga’s understanding of CCFs, there is in fact no relevant difference between the two arguments. Moreover, I (...) strengthen Perszyk’s challenge by highlighting further relevant similarities between CCFs and facts about the laws. (shrink)

The argument from inductive risk (AIR) states that scientists should consider the consequences of hypotheses and methodological choices in the course of ongoing research. It has played a central role in the widespread retreat from the ideal of value-free science. The argument is motivated, to a significant extent, by the laudable concern to use science to better society. I argue that this concern, when taken seriously, tells against the idea that individual working scientists should consider social consequences. First, (...) I show that the AIR assigns scientists a striking task: to frame social decisions and assess their full spectrum of consequences. Then, I argue that scientists should not be assigned such a task. For one thing, if both scientists and policy makers take social consequences into account, we are liable to end up with skewed and biased decisions. For another, scientists are not well-placed to carry out social decision making. I conclude by indicating a context in which the inductive risk line has more force, and by highlighting the importance, in discussing values in science, of attending to units and levels of analysis.

Many philosophers, psychologists, and medical practitioners believe that killing is no worse than letting die on the basis of James Rachels's Bare-Difference Argument. I show that his argument is unsound. In particular, a premise of the argument is that his examples are as similar as is consistent with one being a case of killing and the other being a case of letting die. However, the subject who lets die has both the ability to kill and the ability (...) to let die while the subject who kills lacks the ability to let die. Modifying the latter example so that the killer has both abilities yields a pair of cases with morally different acts. The hypothesis that killing is worse than letting die is the best explanation of this difference. (shrink)

I respond to John Greco’s argument that all forms of internalism in epistemology are either false or uninteresting. The paper divides into two sections. First, I explain precisely what internalists and externalists in epistemology disagree over. This puts us in a position to assess whether Greco’s argument succeeds. Second, I present Greco’s argument and offer two objections.

In the last decade, analytic epistemologists have engaged in a lively debate about Equal Weight, the claim that you should give the credences of epistemic peers the same consideration as your own credences. In this paper, I explore the implications of the debate about Equal Weight for how we should respond to religious disagreement found in the diversity of models of God. I first claim that one common argument against religious exclusivism and for religious pluralism can be articulated as (...) an Equal Weight argument. I then argue that to avoid this argument, religious exclusivists must reject Equal Weight. Next, I maintain that, while the exclusivist complaint that pluralism is self-undermining is incorrect, exclusivists can rightly object that the pluralist’s Equal Weight argument is self-undermining. Thus both exclusivists and pluralists have an interest in rejecting Equal Weight. My final discussion is speculative: I suggest that the goals of those of pluralist persuasion might be better met by religious permissivism, the view that some forms of both exclusivism and pluralism are rational responses to religious disagreement.

Abstract: There has been an ongoing dispute between defenders of world disclosure (understood here in a loosely Heideggerian sense) and advocates of normative debate. I will take up a recent confrontation between Charles Taylor and Robert Brandom over this question as my point of departure for showing how world disclosure can expand the range of normative argument. I begin by distinguishing pre-reflective disclosure—the already interpreted, structured world in which we find ourselves—from reflective disclosure—the discrete intervention of a particular utterance (...) or text. I discuss Taylor’s notion of social imaginaries as a way of thematizing our pre-reflective background and Talal Asad’s critique of Taylor to show how this background can be one space of argument. I then develop my own understanding of reflective disclosure, of which Taylor gives an indequate account, developing my argument with help of literature, including a close analysis of Susan Glaspell short story “A Jury of Her Peers.” This story illustrates how world disclosure can make normative arguments without confining itself to Brandom’s or Habermas’s idea of the exchange of reasons.

While there has been much work on cosmological arguments, novel objections will be presented against the modern day rendition of the Kalām cosmological argument as standardly articulated by William Lane Craig. The conclusion is reached that this cosmological argument and several of its variants do not lead us to believe that there is inevitably a supernatural cause to the universe. Moreover, a conditional argument for atheism will be presented in light of the Big Bang Theory.

By “epistemic pragmatism” in general I will understand the claim that whether propositions instantiate certain key epistemic properties (such as being known or being justifiably believed) depends not just on factors traditionally recognized as epistemic, but also on pragmatic factors, such as how costly it would be to the subject if the proposition were false. In what follows I consider two varieties of epistemic pragmatism. According to what I shall call moderate epistemic pragmatism, how much evidence we need in favor (...) of a proposition in order to know that the proposition is true depends on our preferences. According to what I shall call extreme epistemic pragmatism, on the other hand, our preferences influence our epistemic position at a more basic level, because they help determine how much justification we actually have in favor of the proposition in question. Simplifying brutally, moderate epistemic pragmatism has it that the more worried we are about a proposition’s being false, the more justification we need in order to know it, whereas extreme epistemic pragmatism has it that the more worried we are about a proposition’s being false, the less justification we have for it. Recently, Fantl and McGrath have presented an interesting argument for moderate epistemic pragmatism, an argument which relies on the principle that (roughly) knowledge is sufficient for action (KA). In this paper I argue that KA, together with a plausible principle about second-order evidence, entails extreme epistemic pragmatism. (shrink)

According to the cognitivist strategy, the desire to bring about P provides reasons for intending to bring about P in a way analogous to how perceiving that P provides reasons for believing that P. However, while perceiving P provides reasons for believing P by representing P as true, desiring to bring about P provides reasons for intending to bring about P by representing P as good. This paper offers an argument against this view. My argument proceeds via an (...) appeal to what I call the non-substitutability of perception, the thesis that, given that there is no independent evidence for P, one cannot substitute something that fails to provide reasons with respect to P for the perceptual experience that P, without altering the rational permissibility of believing that P. By contrast, I argue that it is always possible to substitute something that fails to provide reasons for a desire without altering the rational permissibility of an intention based on said desire. I take this to show that a desire does not provide reasons in a way analogous to perceptual experience. (shrink)

Contemporary proponents of theodicy generally believe that a theodical reply to the evidential argument from evil must involve some appeal to the afterlife. In Richard Swinburne's writings on theodicy, however, we find two arguments that may be offered in opposition to this prevailing view. In this paper, these two arguments - the argument from usefulness and the argument from assumed consent - are explained and evaluated. It is suggested that both of these arguments are rendered ineffective by (...) their failure to distinguish between the different ways in which persons may be of-use in the attainment of some good state of affairs.

Proponents of the public goods argument ('PGA') seek to ground the authority of the state on its putative indispensability as a means of providing public goods. But many of the things we take to be public goods – including many of the goods commonly invoked in support of the PGA – are actually what we might term publicized goods. A publicized good is any whose ‘public’ character results only from a policy decision to make some good freely and universally (...) available. This fact poses complications for the PGA, insofar as the set of possible publicized goods is quite extensive indeed. (shrink)

In this article I reconsider David Benatar's primary argument for anti‐natalism—the asymmetry argument—and outline a three‐step process for rejecting it. I begin in Part 2 by reconstructing the asymmetry argument into three main premises. I then turn in Parts 3–5 to explain how each of these premises is in fact false. Finally, I conclude in Part 6 by considering the relationship between the asymmetry argument and the quality of life argument in Benatar's overall case for (...) anti‐natalism and argue that it is the latter argument that is actually doing the work. In this sense, the asymmetry argument is not only unsuccessful in generating Benatar's anti‐natalist conclusion, it is also unnecessary as well. (shrink)

Dutch Book arguments have been presented for static belief systems and for belief change by conditionalization. An argument is given here that a rule for belief change which under certain conditions violates probability kinematics will leave the agent open to a Dutch Book.

In a recent Analysis article, Quentin Smith argues that classical theism is inconsistent with certain consequences of Stephen Hawking's quantum cosmology.1 Although I am not a theist, it seems to me that Smith's argument fails to establish its conclusion. The purpose of this paper is to show what is wrong with Smith's argument. According to Smith, Hawking's cosmological theory includes what Smith calls "Hawking's wave function law." Hawking's wave function law (hereafter, "HL") apparently has, among its consequences, the (...) following claim. (1) The unconditional probability that a universe like this one - i.e., a universe with the metric hij and matter field Φ - should begin to exist is 95%.2 Smith then argues that the theist who accepts HL must also accept that the following sentence was once true.3..

In this paper I offer a counterexample to the so called vagueness argument against restricted composition. This will be done in the lines of a recent suggestion by Trenton Merricks, namely by challenging the claim that there cannot be a sharp cut-off point in a composition sequence. It will be suggested that causal powers which emerge when composition occurs can serve as an indicator of such sharp cut-off points. The main example will be the case of a heap. It (...) seems that heaps might provide a very plausible counterexample to the vagueness argument if we accept the idea that four grains of sand is the least number required to compose a heap—the case has been supported by W. D. Hart. My purpose here is not to put forward a new theory of composition, I only wish to refute the vagueness argument and point out that we should be wary of arguments of its form. (shrink)

Plausibly, no agent ever performs an action without some desire to perform that action. If so, a regress argument shows that, given incompatibilism, we are only rarely free. The argument sidesteps recent objections to this thesis.

This article deals with the relationship between language and thought, focusing on the question of whether language can be a vehicle of thought, as, for example, Peter Carruthers has claimed. We develop and examine a powerful argument—the "argument from explicitness"—against this cognitive role of language. The premises of the argument are just two: (1) the vehicle of thought has to be explicit, and (2) natural languages are not explicit. We explain what these simple premises mean and why (...) we should believe they are true. Finally, we argue that even though the argument from explicitness shows that natural language cannot be a vehicle of thought, there is a cognitive function for language. (shrink)

The Lazy Argument, as it is preserved in historical testimonies, is not logically conclusive. In this form, it appears to have been proposed in favor of part-time fatalism (including past time fatalism). The argument assumes that free will assumption is unacceptable from the standpoint of the logical fatalist but plausible for some of the nonuniversal or part-time fatalists. There are indications that the layout of argument is not genuine, but taken over from a Megarian source and later (...) transformed. The genuine form of the argument seems to be given in different form and far closer to Megarian logical fatalism and its purpose is not to defend laziness. If the historical argument has to lead to a logically satisfactory solution, some additional assumptions and additional tuning is needed. (shrink)

This article seeks to provide a response to the Aloneness Argument Against Classical Theism proposed by Joseph C. Schmid and Ryan T. Mullins. This response focuses on showing the unsoundness of the argument once the Doctrine of Divine Simplicity is reformulated within the essentialist aspectival framework provided by the Aspectival Account. Formulating a response to this argument will thus also serve the further purpose of providing an extension of the Aspectival Account and a needed revision of the (...) Doctrine of Divine Simplicity, which can aid others in their quest to further clarify the nature of this doctrine. (shrink)

My purpose in this paper is to challenge this account of the nature of ethical judgments, and suggest that the reconciliation of their practicality and objectivity is not a genuine philosophical problem. The real issue is rather how to account for the fact that we consider our moral judgments important, authoritative, expressive of our moral personality and of our moral vision, and in this sense both objective and practical. The argument that supports this proposal is phe- nomenological. It starts (...) with the phenomenological consideration that the agent experiences ethical judg- ments as normative: they are conceived and experienced as authoritative and as such as to inform one’s life in a special way. To take phenomenology at face value is to make the experience of the agent intelligible. My conclusion will be that neither realism nor non- cognitivism in their crudest versions engage in the search for the intelligibility of our moral experience, and for that reason they are not appealing alternatives. In their softer and sophisticated versions, both realism and non-cognitivism purport to explain moral phenom- enology, but employ inadequate explanatory devices that seriously compromise their account. As I will argue, the phenomenological argument leads toward a construc- tivist account of ethical judgments. The conception of constructivism I advance is a form of cognitivist irrealism, thus opposed both to realism and non- cognitivism. Here is how my argument will proceed. In section 1, I characterize the debate on ethical objectivity as exploiting the realist image of discovery and the non- cognitivist image of invention. With Wiggins I argue that these alternative metaphors fail to account for moral phenomenology. In section 2, I examine Simon Blackburn’s non-cognitivist reply that utilizes the image of projection, and argue that while more sophisticated than the previous ones, this solution does not account for the authority of ethical judgments. In section 3, I take into consideration McDowell’s analogy between values and secondary qualities and the metaphor of vision. My claim is that his argument succeeds in ruling out realism and non-cognitivism on phenomenological grounds, but it is insufficient as an account of values. My point is not simply that the analogy with percep- tion is limited and incomplete, but that it is inadequate to account for the normative relations that the agent establishes with her surroundings. In section 4, I argue that the appeal to phenomenology supports construc- tivism about normative relations and expose its features. Finally, in section 5, I show the merits of construction as an explanatory device. (shrink)

In this paper Lucas suggests that many of his critics have not read carefully neither his exposition nor Penrose’s one, so they seek to refute arguments they never proposed. Therefore he offers a brief history of the Gödelian argument put forward by Gödel, Penrose and Lucas itself: Gödel argued indeed that either mathematics is incompletable – that is axioms can never be comprised in a finite rule and so human mind surpasses the power of any finite machine – or (...) there exist absolutely unsolvable diophantine problems, and he suggest that the second disjunct is untenable; on the other side, Penrose proposed an argument similar to Lucas’ one but making use of Turing’s theorem. Finally Lucas exposes again his argument and considers some of the most important objections to it. (shrink)

Scholars have often thought that a monistic reading of Aristotle’s definition of the human good – in particular, one on which “best and most teleios virtue” refers to theoretical wisdom – cannot follow from the premises of the ergon argument. I explain how a monistic reading can follow from the premises, and I argue that this interpretation gives the correct rationale for Aristotle’s definition. I then explain that even though the best and most teleios virtue must be a single (...) virtue, that virtue could in principle be a whole virtue that arises from the combination of all the others. I also clarify that the definition of the human good aims at capturing the nature of human eudaimonia only in its primary case. (shrink)

The paper discusses the structure, applications, and plausibility of the much-used parallel-case argument for workplace democracy. The argument rests on an analogy between firms and states according to which the justification of democracy in the state implies its justification in the workplace. The contribution of the paper is threefold. First, the argument is illustrated by applying it to two usual objections to workplace democracy, namely, that employees lack the expertise required to run a firm and that only (...) capital suppliers should have a say over the governance of the firm. Second, the structure of the argument is unfolded. Third, two salient similarities between firms and states regarding their internal and external effects and the standing of their members are addressed in order to asses the potential and limits of the argument, as well as three relevant differences regarding the voluntariness of their membership, the narrowness of their goals, and the stiffness of the competition they face. After considering these similarities and differences, the paper contends that the the parallel-case argument provides a sound reason in favor of democracy in the workplace—a reason, however, that needs to be importantly qualified and that is only pro tanto.

I present a cumulative case for the thesis that we only know propositions that are certain for us. I argue that this thesis can easily explain the truth of eight plausible claims about knowledge: -/- (1) There is a qualitative difference between knowledge and non-knowledge. (2) Knowledge is valuable in a way that non-knowledge is not. (3) Subjects in Gettier cases do not have knowledge. (4) If S knows that P, P is part of S’s evidence. (5) If S knows (...) that P, ~P is epistemically impossible for S. (6) If S knows that P, S can rationally act as if P. (7) If S knows that P, S can rationally stop inquiring whether P. (8) If S knows each of {P1, P2, … Pn}, and competently deduces Q from these propositions, S knows that Q. -/- I then argue that the skeptical costs of this thesis are outweighed by its explanatory power.

Next SectionI challenge the idea that the argument from potential (AFP) represents a valid moral objection to abortion. I consider the form of AFP that was defended by Hare, which holds that abortion is against the interests of the potential person who is prevented from existing. My reply is that AFP, though not unsound by itself, does not apply to the issue of abortion. The reason is that AFP only works in the cases of so-called same number and same (...) people choices, but it falsely presupposes that abortion is such a kind of choice. This refutation of AFP implies that (1) abortion is not only morally permissible but sometimes even morally mandatory and (2) abortion is morally permissible even when the potential person’s life is foreseen to be worth living.
