Brentano never published on Bertrand’s paradox but claimed to have a solution. Adrian Maître has recovered from the Franz Brentano Archive Brentano’s remarks on his solution. They do not give us a worked demonstration of his solution but only an incomplete and in places obscure justification of it. Here I attempt to identify his solution, to explain what seem to me the clearly discernible parts of his justification and to discuss the extent to which the justification succeeds in the light (...) of current work on Bertrand’s paradox.

This paper argues that a view of science, expounded and defended elsewhere, solves the problem of induction. The view holds that we need to see science as accepting a hierarchy of metaphysical theses concerning the comprehensibility and knowability of the universe, these theses asserting less and less as we go up the hierarchy. It may seem that this view must suffer from vicious circularity, in so far as accepting physical theories is justified by an appeal to metaphysical theses in turn (...) justified by the success of science. But this is rebutted. A thesis high up in the hierarchy asserts that the universe is such that the element of circularity, just indicated, is legitimate and justified, and not vicious. Acceptance of the thesis is in turn justified without appeal to the success of science. It may seem that the practical problem of induction can only be solved along these lines if there is a justification of the truth of the metaphysical theses in question. It is argued that this demand must be rejected as it stems from an irrational conception of science. (shrink)

This paper considers objections to Popper's views on scientific method. It is argued that criticism of Popper's views, developed by Kuhn, Feyerabend, and Lakatos, are not too damaging, although they do require that Popper's views be modified somewhat. It is argued that a much more serious criticism is that Popper has failed to provide us with any reason for holding that the methodological rules he advocates give us a better hope of realizing the aims of science than any other set (...) of rules. Consequently, Popper cannot adequately explain why we should value scientific theories more than other sorts of theories ; which in turn means that Popper fails to solve adequately his fundamental problem, namely the problem of demarcation. It is suggested that in order to get around this difficulty we need to take the search for explanations as a fundamental aim of science. (shrink)

Philosophy of science is seen by most as a meta-discipline – one that takes science as its subject matter, and seeks to acquire knowledge and understanding about science without in any way affecting, or contributing to, science itself. Karl Popper’s approach is very different. His first love is natural philosophy or, as he would put it, cosmology. This intermingles cosmology and the rest of natural science with epistemology, methodology and metaphysics. Paradoxically, however, one of his best known contributions, his proposed (...) solution to the problem of demarcation, helps to maintain the gulf that separates science from metaphysics, thus fragmenting cosmology into falsifiable science on the one hand, untestable philosophy on the other. This has damaging repercussions for a number of issues Popper tackles, from the problem of induction to simplicity of theory and quantum theory. But his proposed solution to the demarcation problem is untenable. Metaphysical assumptions are an integral part of scientific knowledge, inherent in the persistent acceptance of unified theories against the evidence. Once this is appreciated, it becomes obvious that natural philosophy, a synthesis of science and philosophy, is both more rigorous and of greater intellectual value than the two dissociated components we have today. What Popper sought for could come to full fruition. Problems that Popper tackled, from the problem of induction, to the problem of unity of theory, problems of quantum theory, and problems concerning the scope and limits of physics, all receive more adequate resolution within the new, fully-fledged natural philosophy.

The principle of indifference is supposed to suffice for the rational assignation of probabilities to possibilities. Bertrand advances a probability problem, now known as his paradox, to which the principle is supposed to apply; yet, just because the problem is ill‐posed in a technical sense, applying it leads to a contradiction. Examining an ambiguity in the notion of an ill‐posed problem shows that there are precisely two strategies for resolving the paradox: the distinction strategy and the well‐posing strategy. The main (...) contenders for resolving the paradox, Marinoff and Jaynes, offer solutions which exemplify these two strategies. I show that Marinoff’s attempt at the distinction strategy fails, and I offer a general refutation of this strategy. The situation for the well‐posing strategy is more complex. Careful formulation of the paradox within measure theory shows that one of Bertrand’s original three options can be ruled out but also shows that piecemeal attempts at the well‐posing strategy will not succeed. What is required is an appeal to general principle. I show that Jaynes’s use of such a principle, the symmetry requirement, fails to resolve the paradox; that a notion of metaindifference also fails; and that, while the well‐posing strategy may not be conclusively refutable, there is no reason to think that it can succeed. So the current situation is this. The failure of Marinoff’s and Jaynes’s solutions means that the paradox remains unresolved, and of the only two strategies for resolution, one is refuted and we have no reason to think the other will succeed. Consequently, Bertrand’s paradox continues to stand in refutation of the principle of indifference. (shrink)

We need urgently to bring about a revolution in universities around the world, wherever possible, so that they take their fundamental task to be, not to acquire and apply knowledge, but rather to help humanity learn how to resolve conflicts and problems of living in increasingly cooperatively rational ways, so that we may make progress towards a good, genuinely civilized, wise world. The pursuit of knowledge would be a vital but subsidiary task. I have argued for the urgent need for (...) such an academic revolution for nearly 50 years, ever since the publication of two books: What’s Wrong With Science? Towards a People’s Rational Science of Delight and Compassion, 1976, and From Knowledge to Wisdom: A Revolution for Science and the Humanities, 1984, both available free online. This article, written in preparation for a talk given to Pittsburgh University on the 15th September 2023, gives an outline of my baffled struggles with problems of philosophy, science, literature and life that led up to the discovery of the urgent need for an intellectual and institutional revolution in universities around the world, needed in order to galvanize the social revolution required to enable us to make progress to a world in which peace, justice, democracy, individual freedom, sustainable prosperity, the possibility of a good life, are available to all, insofar as that is attainable.

Hermann Cohen’s 1871 classic, Kants Theorie der Erfahrung, had a formative influence, not only on the Marburg school’s reading of Kant, but on their entire conception of philosophy. This influence was further magnified by the substantially revised and expanded second edition of 1885 and the yet further expanded third edition of 1918. Neo-Kantianism was the dominant philosophical movement in Germany in the late nineteenth and twentieth centuries, which means that a work, ostensibly, of Kant scholarship had an influence on the (...) development of German philosophy that few works of secondary literature can claim.

This paper examines Plato’s conception of shame and the role intoxication plays in cultivating it in the Laws. Ultimately, this paper argues that there are two accounts of shame in the Laws. There is a public sense of shame that is more closely tied to the rational faculties and a private sense of shame that is more closely tied to the non-rational faculties. Understanding this division between public and private shame not only informs our understanding of Plato’s moral psychology, but (...) his political and ethical theory as well. (shrink)

There is substantial textual evidence that Kant held the doctrine of double affection: subjects are causally affected both by things in themselves and by appearances. However, Kant commentators have been loath to attribute this view to him, for the doctrine of double affection is widely thought to face insuperable problems. I begin by explaining what I take to be the most serious problem faced by the doctrine of double affection: appearances cannot cause the very experience in virtue of which they (...) have their empirical properties. My solution consists in distinguishing the sense of ‘experience’ in which empirical objects cause experience from the sense of ‘experience’ in which experience determines empirical objects. I call the latter “universal experience”. I develop my conception of universal experience, and then I explain how it solves the problem of double affection. I conclude by addressing several objections. (shrink)

Some opponents of abortion claim that fetuses are persons from the moment of conception. Following Berg (2017), let us call these individuals “Personhood-At-Conception” (or PAC), opponents of abortion. Berg argues that if fetuses are persons from the moment of conception, then miscarriage kills far more people than abortion. As such, PAC opponents of abortion face the following dilemma: They must “immediately” and “substantially” shift their attention, resources, etc., toward preventing miscarriage or they must admit that they do not actually believe (...) that fetuses are persons from the moment of conception (or, at least, they must recognize that they are not acting in ways that are consistent with this belief). In this essay, I show that Berg’s argument fails at each step. Specifically, after outlining her argument (in section 1), I consider the central claim of Berg’s style of argument: That “miscarriage…is much deadlier than abortion.” In section 2, I argue that this claim is false (when taken literally) and misleading otherwise. In section 3, I show that Berg’s style of argument is identical in structure to a criticism that is sometimes levied against the recent “Black Lives Matter” movement. In the latter context, the argument has been vehemently rejected. I argue that Berg’s style of argument should be rejected for the same reasons. Finally, in section 4, I show that Berg’s suggestion that opponents of abortion should divert “substantial” amounts of money and attention to miscarriage prevention faces two problems. First, these claims are made without any evidence regarding the actual priorities and spending habits of PAC opponents of abortion. If we are told “not enough is being done,” one wonders: What is being done and how much counts as “enough”? Berg gives no answer to either question. Second, even if it is true that opponents of abortion do not pay substantial attention to miscarriage prevention, Berg fails to notice that this may be for good reason. I conclude that PAC opponents of abortion do not face the dilemma that Berg presents. (shrink)

An important suggestion of objective Bayesians is that the maximum entropy principle can replace a principle which is known to get into paradoxical difficulties: the principle of indifference. No one has previously determined whether the maximum entropy principle is better able to solve Bertrand’s chord paradox than the principle of indifference. In this paper I show that it is not. Additionally, the course of the analysis brings to light a new paradox, a revenge paradox of the chords, that is unique (...) to the maximum entropy principle. (shrink)

Dretske proposes a theory of knowledge in terms of a theory of information, but wishes to deny that empirical knowledge settles the large question of scepticism. This leads him to deny the closure of knowledge under known entailment. In a recent paper Jäger argues that Dretske's theory of information entails closure for knowledge, 'at least for the kind of propositions here at issue'. If Jäger is right, Dretske is seriously embarrassed and must give something up. In this paper I show (...) that there are two flaws in Jäger's argument. The principle of informational closure considered by Jäger is incompatible with Dretske's theory of information, and Jäger's argument that Dretske is committed to a certain kind of substitution instance of that principle of informational closure is invalid. I propose adequacy conditions on signalled information and use them to motivate a formulation of a general closure principle for signalled information. I show that Dretske's account of information satisfies the adequacy conditions, but in a way which commits him to an instance of the general closure principle. I argue that Dretske is consequently committed to closure for some cases of knowledge for which he wishes to deny closure. Finally, I sketch how, on the basis of the closure principle to which Dretske is committed, Jäger's broader argument may yet go through. (shrink)

What ought to be the aims of science? How can science best serve humanity? What would an ideal science be like, a science that is sensitively and humanely responsive to the needs, problems and aspirations of people? How ought the institutional enterprise of science to be related to the rest of society? What ought to be the relationship between science and art, thought and feeling, reason and desire, mind and heart? Should the social sciences model themselves on the natural sciences: (...) or ought they to take a different form if they are to serve the interests of humanity objectively, sensitively and rigorously? Might it be possible to get into human life, into art, education, politics, industry, international affairs, and other domains of human activity, the same kind of progressive success that is found so strikingly, on the intellectual level, within science? These are some of the questions tackled by What’s Wrong With Science? But the book is no abstruse treatise on the philosophy of science. Most of it takes the form of a passionate debate between a Scientist and a Philosopher, a debate that is by turns humorous, ironical, bitter, dramatically explosive. Even as the argument explores the relationship between thought and feeling, reason and desire, the two main protagonists find it necessary to examine their own feelings and motivations. (shrink)

Martin Scorsese’s 1976 film Taxi Driver is widely considered a cinematic masterpiece. Existing scholarly deconstructions focus on prevalent themes of masculinity, violence, and exploitation. This work reinterprets the central narrative as a revenge story in three parts, using cinematic context; the occurrences and actions of the protagonist – the eponymous taxi driver Travis Bickle - to answer the question of whether revenge is ever morally justifiable.

In this paper, I examine Kant's famous objection to the ontological argument: existence is not a determination. Previous commentators have not adequately explained what this claim means, how it undermines the ontological argument, or how Kant argues for it. I argue that the claim that existence is not a determination means that it is not possible for there to be non-existent objects; necessarily, there are only existent objects. I argue further that Kant's target is not merely ontological arguments as such (...) but the larger ‘ontotheist’ metaphysics they presuppose: the view that God necessarily exists in virtue of his essence being contained in, or logically entailed by, his essence. I show that the ontotheist explanation of divine necessity requires the assumption that existence is a determination, and I show that Descartes and Leibniz are implicitly committed to this in their published versions of the ontological argument. I consider the philosophical motivations for the claim that existence is a determination and then I examine Kant's arguments in the Critique of Pure Reason against it. (shrink)

While scholars have extensively discussed Kant’s treatment of the Principle of Sufficient Ground in the Antinomies chapter of the Critique of Pure Reason, and, more recently, his relation to German rationalist debates about it, relatively little has been said about the exact notion of ground that figures in the PSG. My aim in this chapter is to explain Kant’s discussion of ground in the lectures and to relate it, where appropriate, to his published discussions of ground.

For three decades I have expounded and defended aim-oriented empiricism, a view of science which, l claim, solves a number of problems in the philosophy of science and has important implications for science itself and, when generalized, for the whole of academic inquiry, and for our capacity to solve our current global problems. Despite these claims, the view has received scant attention from philosophers of science. Recently, however, David Miller has criticized the view. Miller’s criticisms are, however, not valid.

Kant’s distinction between the determining and reflecting power of judgment in the third Critique is not well understood in the literature. A mainstream view unifies these by making determination the telos of all acts of judgment (Longuenesse 1998). On this view, all reflection is primarily in the business of producing empirical concepts for cognition, and thus has what I call a determinative ideal. I argue that this view fails to take seriously the independence and autonomy of the ‘power of judgment’ (...) [Urteilskraft] as a higher cognitive faculty in its own right with its own a priori principle. Instead of seeing merely reflecting judgments as failed or incomplete acts of judgment, I argue that these are in fact paradigmatic of the activity of the power of judgment. More precisely, the reflecting power of judgment just is the power of judgment. Accordingly, reflecting judgment takes precedence over determining judgment; while the former operates according to a law that it gives itself, the latter requires another higher cognitive faculty to provide its principle. On my view, reflecting judgment should be understood as the capacity for purposive subsumption—most clearly seen in the activity of mere reflection. (shrink)

That Kant sees the faculties of imagination and judgment as closely related is not controversial. Yet precisely how they relate to each other, especially across his Critical philosophy, is less clear. In this paper, I consider the relationship between what Kant calls the ‘power of imagination’ [Einbildungskraft] and the ‘power of judgment’ [Urteilskraft]. I argue for the following claim: insofar as the power of judgment is the faculty of thinking particulars under universals, the power of imagination is the faculty of (...) producing and providing particulars for judgment—either to reflect on or to subsume under universals. Such an account reveals that our capacity for imagination is intimately bound up with our capacity to judge. (shrink)

Unlike almost all other philosophers of science, Karl Popper sought to contribute to natural philosophy or cosmology – a synthesis of science and philosophy. I consider his contributions to the philosophy of science and quantum theory in this light. There is, however, a paradox. Popper’s most famous contribution – his principle of demarcation – in driving a wedge between science and metaphysics, serves to undermine the very thing he professes to love: natural philosophy. I argue that Popper’s philosophy of science (...) is, in this respect, defective. Science cannot proceed without making highly problematic metaphysical assumptions concerning the comprehensibility and knowability of the universe. Precisely because these assumptions are problematic, rigour requires that they be subjected to sustained critical scrutiny, as an integral part of science itself. Popper’s principle of demarcation must be rejected. Metaphysics and philosophy of science become a vital part of science. Natural philosophy is reborn. A solution to the problem of what it means to say a theory is unified is proposed, a problem Popper failed to solve. In The Logic of Scientific Discovery, Popper made important contributions to the interpretation of quantum theory, especially in connection with Heisenberg's uncertainty relations. Popper's advocacy of natural philosophy has important implications for education. (shrink)

After a sketch of the optimism and high aspirations of History and Philosophy of Science when I first joined the field in the mid 1960s, I go on to describe the disastrous impact of "the strong programme" and social constructivism in history and sociology of science. Despite Alan Sokal's brilliant spoof article, and the "science wars" that flared up partly as a result, the whole field of Science and Technology Studies is still adversely affected by social constructivist ideas. I then (...) go on to spell out how in my view STS ought to develop. It is, to begin with, vitally important to recognize the profoundly problematic character of the aims of science. There are substantial, influential and highly problematic metaphysical, value and political assumptions built into these aims. Once this is appreciated, it becomes clear that we need a new kind of science which subjects problematic aims - problematic assumptions inherent in these aims - to sustained imaginative and critical scrutiny as an integral part of science itself. This needs to be done in an attempt to improve the aims and methods of science as science proceeds. The upshot is that science, STS, and the relationship between the two, are all transformed. STS becomes an integral part of science itself. And becomes a part of an urgently needed campaign to transform universities so that they become devoted to helping humanity create a wiser world.

In 1984 the author published From Knowledge to Wisdom, a book that argued that a revolution in academia is urgently needed, so that problems of living, including global problems, are put at the heart of the enterprise, and the basic aim becomes to seek and promote wisdom, and not just acquire knowledge. Every discipline and aspect of academia needs to change, and the whole way in which academia is related to the rest of the social world. Universities devoted to the (...) pursuit of knowledge and technological know-how betray reason and, as a result, betray humanity. As a result of becoming more intellectually rigorous, academic inquiry becomes of far greater benefit to humanity. If the revolution argued for all those years ago had been taken up and put into academic practice, we might now live in a much more hopeful world than the one that confronts us. Humanity might have begun to learn how to solve global problems; the Amazon rain forests might not face destruction; we might not be faced with mass extinction of species; Brexit might not have been voted for in the UK in 2016, and Trump might not have been elected President in the USA. An account is given of work published by the author during the years 1972 to 2021 that expounds and develops the argument. The conclusion is that we urgently need to create a high-profile campaign devoted to transforming universities in the way required so that humanity may learn how to make social progress towards a better, wiser, more civilized, enlightened world.

The Heythrop Journal, Volume 63, Issue 1, Page 57-63, January 2022.

In Plato’s Laws, the Athenian Stranger maintains that law should consist of both persuasion (πειθώ) and compulsion (βία) (IV.711c, IV.718b-d, and IV.722b). Persuasion can be achieved by prefacing the laws with preludes (προοίμια), which make the citizens more eager to obey the laws. Although scholars disagree on how to interpret the preludes’ persuasion, they agree that the preludes instill true beliefs and give citizens good reasons for obeying the laws. In this paper I refine this account of the preludes by (...) arguing that the primary purpose of the preludes is to motivate correct action, and that for citizens who lack rational-governance this is achieved via useful false beliefs. That is to say, in many cases, the prelude functions as a “noble lie” (γενναῖον ψεῦδος). (shrink)

In this thesis I provide an account of the faculty of the mind that Kant calls ‘the power of judgment’ [Urteilskraft]. While there is an abundance of literature on various aspects of Kant’s theory of judgment in the Critical philosophy, there has been no sustained treatment of the nature of the faculty that is the subject of the third Critique (1790). I argue that the power of judgment is a fundamentally reflective, affective, and orientational capacity that occupies a central place (...) within Kant’s account of the human mind. To this end, I trace the development of Kant’s thinking on judgment—from the pre-Critical to the Critical period, as well as from the first to the third Critique—to show how it continues to gain prominence within Kant’s taxonomy of the mind.

In my book The Comprehensibility of the Universe (OUP, 1998), I argue for a new conception of science that construes science as adopting a hierarchy of increasingly contentless cosmological assumptions about the comprehensibility and knowability of the universe. This view, I argue, solves outstanding problems about science, such as problems of induction, simplicity and verisimilitude. In his essay review of my book (Philosophy 75, 2000, 296–309) Friedel Weinert criticizes me for defending a number of views about science. But, as I (...) make clear from quotations from the book, I do not defend the views that Weinert attributes to me. (shrink)

This seminal paper, which marks a turning point of the chemical revolution, is presented for the first time in a complete English translation. In this first half Lavoisier undermines phlogiston chemistry by arguing that his French contemporaries had replaced Stahl’s original theory with radically different systems that conceptualised the phlogiston principle in completely incompatible ways. He refutes their claims by showing that these later models were riddled with inconsistencies as to phlogiston’s weight, its ability to penetrate glass and its role (...) as a source of colour and odour in chemical compounds.

Jake Greenblum and Ryan K Hubbard argue that physicians, nurses, clinical ethicists and ethics committee members should not cite religious considerations when helping patients (or their proxies) make medical decisions. They provide two arguments for this position: The Public Reason Argument and the Fiduciary Argument. In this essay, I show that the Public Reason Argument fails. Greenblum and Hubbard may provide good reason to think that physicians should not invoke their own religious commitments as reasons for a particular medical decision. (...) But they fail to show that it is wrong for physicians to cite the patient’s own religious commitments as reasons for a particular decision. As such, if Greenblum and Hubbard’s thesis is to survive, the Fiduciary Argument (or some unmentioned argument) will have to do the bulk of the work. (shrink)

This paper argues against the claim that Frege is committed to an infinite hierarchy of senses. Carnap and Kripke, along with many others, argue the contrary; I expose where all such arguments go astray. Invariably these arguments assume (without citation) that Frege holds that sense and reference are always distinct. This is the fulcrum upon which the hierarchy is hoisted. The counter to this assumption is based on two important but neglected passages. The locution ‘indirect sense’ has no ontological significance (...) for Frege. It was just a ‘short expression’ (his term) to indicate that the customary relation between sign, sense, and reference is suspended in what he called the exception case of indirect context. Once the hierarchy is abandoned, the alleged problem of just what indirect sense is, as well as questions as to why Frege said so little about it and why he did not examine iterative indirect contexts are resolved. Of course, with no hierarchy, Davidson’s “unlearnability argument” turns out to be a non-starter. Some objections to my interpretation are considered and answered. Additionally, comparisons to Dummett’s one-level view of sense, which is similar to mine are made, as well as to some two-level views (Parsons and Skiba). (shrink)

In this paper, I argue that the two versions of divided line create problems that cannot be solved — with or without the hypothesis that the objects belonging to the level of διάνοια on the divided line are intermediates. I also argue that the discussion of arithmetic and calculation does not fit Aristotle’s attribution of intermediates to Plato and provides no support for the claim that Plato had such intermediates in mind when he talked about διάνοια in the Republic. The (...) upshot of my argument is negative: even if Aristotle’s report about Plato and intermediates is correct, there is no evidence for such objects provided in the passages I review from the Republic. If they are to be found in Plato, it will have to be elsewhere that they are found. (shrink)

For four decades it has been argued that we need to adopt a new conception of science called aim-oriented empiricism. This has far-reaching implications and repercussions for science, the philosophy of science, academic inquiry in general, conception of rationality, and how we go about attempting to make progress towards as good a world as possible. Despite these far-reaching repercussions, aim-oriented empiricism has so far received scant attention from philosophers of science. Here, sixteen objections to the validity of the argument for (...) aim-oriented empiricism are subjected to critical scrutiny. (shrink)

One of Bolzano’s objections to Kant’s way of drawing the analytic-synthetic distinction is that it only applies to judgments within a narrow range of syntactic forms, namely, universal affirmative judgments. According to Bolzano, Kant cannot account for judgments of other syntactic forms that, intuitively, are analytic. A recent paper by Ian Proops also attributes to Kant the view that analytic judgments beyond a limited range of syntactic forms are impossible. I argue that, correctly understood, Kant’s conception of analyticity allows for (...) analytic judgments of a wider range of syntactic forms. (shrink)

This issue of Christian Bioethics explores theological, metaphysical, and ethical questions surrounding emerging reproductive technologies. Narratives concerning such technologies are often manipulated via “language games.” Language games involve toying with language to ensure that one’s vision of the good gains or retains political prominence. Such games are common in academic discussions of “artificial womb” technologies. Abortion proponents, for example, are already using language to dehumanize subjects within “artificial wombs.” This is unsurprising. Were relevant subjects considered persons, then abortion access (and (...) other forms of “reproductive autonomy”) might be curtailed. Here, I show that abortion proponents’ language games often depend on dubious metaphysical claims. Second, I argue that Christians should oppose dehumanizing language games, since those games undermine “neighbor-love,” which Christians are commanded to show others. I also highlight how discussions of other technologies—such as medication abortion—are affected by confused (or manipulative) language. Ultimately, the language games I critique aim to preserve and expand the “rights” of the powerful to dehumanize, control, and kill vulnerable human beings. Since neighbor-love commands Christians to provide for “the least of these,” however, Christians must expose these manipulative language games, refute them, and resist the corrupt ideologies from which they flow.

The aim of the Schematism chapter of the Critique of Pure Reason is to solve the problem posed by the “inhomogeneity” of intuitions and categories: the sensible properties of objects represented in intuition are of a different kind than the properties represented by categories. Kant's solution is to introduce what he calls “transcendental schemata,” which mediate the subsumption of objects under categories. I reconstruct Kant's solution in terms of two substantive premises, which I call Subsumption Sufficiency (i.e., that subsuming an (...) object under a transcendental schema is sufficient to subsume it under the corresponding category) and Real Possibility (i.e., that it is really possible to subsume objects under each of the transcendental schemata). These two principles, together with a trivial modal one (the Subsumption-Possibility Link), entail that it is possible to subsume objects under categories; in other words, the argument of the Schematism is valid. The main work of the paper consists in reconstructing Kant's arguments for, and explanations of, these premises. I argue that they hinge on Kant's claim that transcendental schemata are “time-determinations,” which I interpret to mean: rules for reflexively representing the temporal relations among our own representational states. On the basis of this reading, I reconstruct Kant's argument for Subsumption Sufficiency, category by category. I also explain why Real Possibility follows almost immediately. Granting Kant the argument up to this point in the Critique, the argument of the Schematism is sound. (shrink)

For over 30 years I have argued that we need to construe science as accepting a metaphysical proposition concerning the comprehensibility of the universe. In a recent paper, Fred Muller criticizes this argument, and its implication that Bas van Fraassen’s constructive empiricism is untenable. In the present paper I argue that Muller’s criticisms are not valid. The issue is of some importance, for my argument that science accepts a metaphysical proposition is the first step in a broader argument intended to (...) demonstrate that we need to bring about a revolution in science, and ultimately in academic inquiry as a whole so that the basic aim becomes wisdom and not just knowledge.

According to Fumerton in his "How Does Perception Justify Belief?", it is misleading or wrong to say that perception is a source of justification for beliefs about the external world. Moreover, reliability does not have an essential role to play here either. I agree, and I explain why in section 1, using novel considerations about evil demon scenarios in which we are radically deceived. According to Fumerton, when it comes to how sensations or experiences supply justification, they do not do (...) so on their own, and instead only do so only in conjunction with support for background beliefs about how the sensations or experiences are best explained. Here I disagree. In section 2, I first clarify the question of whether sensations or experiences provide justification on their own. I then respond to Fumerton’s arguments that use considerations about concept-possession and about how to close possible gaps between experience and truth. In section 3, I develop my main concern about his positive view, where that concern also brings out some of the merits of the view that experiences do justify beliefs about the external world on their own.

This paper presents a philosophical argument for divine providence by Aquinas. I suggest that upon returning to Aristotle’s Physics and Metaphysics to prepare his commentaries on these texts, Aquinas recognized that his stock argument from natural teleology to divine providence (the fifth way and its versions) needed to be filled out. Arguments from natural teleology can prove that God’s providence extends to what happens for the most part, but they cannot show that God’s providence also includes what happens for the (...) least part. In order to prove the latter, Aquinas claims that one must argue from a higher science, which he then does with all characteristic clarity. This paper presents this argument, discusses what this means for his previous arguments from teleology, and discusses the argument’s relevance to the contemporary discussion about creation and evolution.

A lively topic of debate in decision theory over recent years concerns our understanding of the different risk attitudes exhibited by decision makers. There is ample evidence that risk-averse and risk-seeking behaviours are widespread, and a growing consensus that such behaviour is rationally permissible. In the context of clinical medicine, this matter is complicated by the fact that healthcare professionals must often make choices for the benefit of their patients, but the norms of rational choice are conventionally grounded in a (...) decision maker’s own desires, beliefs and actions. The presence of both doctor and patient raises the question of whose risk attitude matters for the choice at hand and what to do when these diverge. Must doctors make risky choices when treating risk-seeking patients? Ought they to be risk averse in general when choosing on behalf of others? In this paper, I will argue that healthcare professionals ought to adopt a deferential approach, whereby it is the risk attitude of the patient that matters in medical decision making. I will show how familiar arguments for widely held anti-paternalistic views about medicine can be straightforwardly extended to include not only patients’ evaluations of possible health states, but also their attitudes to risk. However, I will also show that this deferential view needs further refinement: patients’ higher-order attitudes towards their risk attitudes must be considered in order to avoid some counterexamples and to accommodate different views about what sort of attitudes risk attitudes actually are.

The other chapters in this volume discuss the important, but neglected, topic of systematicity in metaphysics. In this chapter I begin by taking a step back and asking: why is systematicity important in metaphysics? Assuming that metaphysics should be systematic, why is this the case? I canvas some answers that emerge naturally within contemporary philosophy and argue that none of them adequately explains why metaphysics should be systematic. I then turn to Kant’s account of systematicity for his explanation. I argue (...) that, while Kant’s explanation of the systematicity of metaphysics rests on a host of additional weighty philosophical commitments that many philosophers would rather do without (e.g., transcendental idealism), he is not alone in this. The contemporary answers I earlier found wanting can be transformed into satisfying explanations, I argue, but only at the cost of philosophical commitments at least as weighty as Kant’s. I conclude on a note of agnosticism: it is far from clear whether contemporary philosophy has done, or can do, better than Kant at explaining the role of systematicity in metaphysics. (shrink)

The privation theory of evil (PTE) states that evil is the absence of some good that is supposed to be present. For example, if vision is an intrinsic good, and if human beings are supposed to have vision, then PTE implies that a human being’s lacking vision is an evil, or a bad state of affairs. The mere-difference view of disability (MDD) states that disabilities like blindness are not inherently bad. Therefore, it would seem that lacking sight is not a (...) bad state of affairs. Thus PTE and MDD seem to be in tension. This essay discusses that apparent tension and explains how it might be resolved without doing violence to either view. Given the prominence of PTE in the history of Christian theology, and the wide support for MDD among disability theorists, it is worth finding a way to harmonize these two views. (shrink)

Contemporary debate surrounding the nature of scientific progress has focused upon the precise role played by justification, with two realist accounts having dominated proceedings. Recently, however, a third realist account has been put forward, one which offers no role for justification at all. According to Finnur Dellsén’s (Stud Hist Philos Sci Part A 56:72–83, 2016) noetic account, science progresses when understanding increases, that is, when scientists grasp how to correctly explain or predict more aspects of the world that they could (...) before. In this paper, we argue that the noetic account is severely undermotivated. Dellsén provides three examples intended to show that understanding can increase absent the justification required for true belief to constitute knowledge. However, we demonstrate that a lack of clarity in each case allows for two contrasting interpretations, neither of which serves its intended purpose. On the first, the agent involved lacks both knowledge and understanding; and, on the second, the agent involved successfully gains both knowledge and understanding. While neither interpretation supports Dellsén’s claim that understanding can be prised apart from knowledge, we argue that, in general, agents in such cases ought to be attributed neither knowledge nor understanding. Given that the separability of knowledge and understanding is a necessary component of the noetic account, we conclude that there is little support for the idea that science progresses through increasing understanding rather than the accumulation of knowledge.

In his important recent book Schroeder proposes a Humean theory of reasons that he calls hypotheticalism. His rigourous account of the weight of reasons is crucial to his theory, both as an element of the theory and constituting his defence to powerful standard objections to Humean theories of reasons. In this paper I examine that rigourous account and show it to face problems of vacuity and consonance. There are technical resources that may be brought to bear on the problem of (...) vacuity but implementation is not simple and philosophical motivation a further difficulty. Even supposing vacuity is fixed, the problems of consonance bring to light a different obstruction lying in Schroeder’s path. There is a difference between the general weighing of reasons and the context specificity of the correct placing of weight on them in deliberation and this difference cannot be fixed by the resources in the account. For these reasons we are still waiting for a plausible Humean theory of reasons. (shrink)

Lakatos held that science proceeds by means of competing research programme, each with its own “hard core” or paradigm. He intended this view to reconcile the competing views of Kuhn and Popper. But what Lakatos overlooked is that science needs to be construed to be one gigantic research programme with, as its “hard core”, a metaphysical thesis that asserts that the universe is such that there is an inherent unity in the laws that govern the way physical phenomena occur. The (...) conception of science that emerges from this insight succeeds in doing what Lakatos’s own view fails to do; it has fruitful implications for science itself, and solves the problem of induction.

Opponents of abortion are often described as ‘inconsistent’ (hypocrites) in terms of their beliefs, actions and/or priorities. They are alleged to do too little to combat spontaneous abortion, they should be adopting cryopreserved embryos with greater frequency and so on. These types of arguments—which we call ‘inconsistency arguments’—conform to a common pattern. Each specifies what consistent opponents of abortion would do (or believe), asserts that they fail to act (or believe) accordingly and concludes that they are inconsistent. Here, we show (...) that inconsistency arguments fail en masse. In short, inconsistency arguments typically face four problems. First, they usually fail to account for diversity among opponents of abortion. Second, they rely on inferences about consistency based on isolated beliefs shared by some opponents of abortion (and these inferences often do not survive once we consider other beliefs opponents of abortion tend to hold). Third, inconsistency arguments usually ignore the diverse ways in which opponents of abortion might act on their beliefs. Fourth, inconsistency arguments criticise groups of people without threatening their beliefs (eg, that abortion is immoral). Setting these problems aside, even supposing inconsistency arguments are successful, they hardly matter. In fact, in the two best-case scenarios—where inconsistency arguments succeed—they either encourage millions of people to make the world a (much) worse place (from the critic’s perspective) or promote epistemically and morally irresponsible practices. We conclude that a more valuable discussion would be had by focusing on the arguments made by opponents of abortion rather than opponents themselves. (shrink)

The question of truth is a broadly broached subject in Philosophy as it features along the entire historical and polemical growth of the discipline right from the time of the Ancients down to our Post-Modern era. Yet, the delimiting realization of being unable to register general success in our dogged attempts at truth and knowledge, mostly stares us blankly in the face, for matters on which philosophy endeavours to speculate on, are beyond the reach of definite knowledge.1 Our theories of (...) the universe open up to modifications, refutations, and further propositions, evidencing a historical development in philosophical inquiry. This generally is the growth of our science, of our knowledge. This paper critically seeks to examine Popper’s notion of verisimilitude. It takes us through the scientist’s journey from ignorance to truth, and the difference between probability and verisimilitude. It addresses the relevance of the theory of content in understanding verisimilitude, under its distinctions as quantitative and qualitative. Finally, it discusses corroboration and the criteria for theory-choice. (shrink)

Aristotle’s doctrine of the mean states that each moral virtue stands opposed to two types of vice: one of excess and one of deficiency, respectively. Critics claim that some virtues—like honesty, fair-mindedness, and patience—are counterexamples to Aristotle’s doctrine. Here, I develop a generalizable strategy to defend the doctrine of the mean against such counterexamples. I argue that not only is the doctrine of the mean defensible, but taking it seriously also allows us to gain substantial insight into particular virtues. Failure (...) to take the doctrine seriously, moreover, exposes us to the risk of mistaking certain vices for virtues. (shrink)
