Hilbert’s choice operators τ and ε, when added to intuitionistic logic, strengthen it. In the presence of certain extensionality axioms they produce classical logic, while in the presence of weaker decidability conditions for terms they produce various superintuitionistic intermediate logics. In this thesis, I argue that there are important philosophical lessons to be learned from these results. To make the case, I begin with a historical discussion situating the development of Hilbert’s operators in relation to his evolving program in the (...) foundations of mathematics and in relation to philosophical motivations leading to the development of intuitionistic logic. This sets the stage for a brief description of the relevant part of Dummett’s program to recast debates in metaphysics, and in particular disputes about realism and anti-realism, as closely intertwined with issues in philosophical logic, with the acceptance of classical logic for a domain reflecting a commitment to realism for that domain. Then I review extant results about what is provable and what is not when one adds epsilon to intuitionistic logic, largely due to Bell and DeVidi, and I give several new proofs of intermediate logics from intuitionistic logic+ε without identity. With all this in hand, I turn to a discussion of the philosophical significance of choice operators. Among the conclusions I defend are that these results provide a finer-grained basis for Dummett’s contention that commitment to classically valid but intuitionistically invalid principles reflect metaphysical commitments by showing those principles to be derivable from certain existence assumptions; that Dummett’s framework is improved by these results as they show that questions of realism and anti-realism are not an “all or nothing” matter, but that there are plausibly metaphysical stances between the poles of anti-realism and realism, because different sorts of ontological assumptions yield intermediate rather than classical logic; and that these intermediate positions between classical and intuitionistic logic link up in interesting ways with our intuitions about issues of objectivity and reality, and do so usefully by linking to questions around intriguing everyday concepts such as “is smart,” which I suggest involve a number of distinct dimensions which might themselves be objective, but because of their multivalent structure are themselves intermediate between being objective and not. Finally, I discuss the implications of these results for ongoing debates about the status of arbitrary and ideal objects in the foundations of logic, showing among other things that much of the discussion is flawed because it does not recognize the degree to which the claims being made depend on the presumption that one is working with a very strong logic.

In this paper, we reconstruct Kant’s notion of the practically conditioned, introduced in the Dialectic of Pure Practical Reason, by drawing on Kant’s general account of the faculty of reason presented in the Transcendental Dialectic of the Critique of Pure Reason. We argue that practical reason’s activity of seeking the practically unconditioned for a given condition generates two different conceptions of the practically unconditioned and identify these as virtue and (the ideal of) happiness. We then account for how and why (...) reason proceeds to combine these two distinct ideas into the composite idea of the highest good. Last, we draw on our discussion to determine more precisely what Kant intends by the ‘supremacy’ of virtue within reason’s idea of the highest good. (shrink)

We discuss the philosophical implications of formal results showing the con- sequences of adding the epsilon operator to intuitionistic predicate logic. These results are related to Diaconescu’s theorem, a result originating in topos theory that, translated to constructive set theory, says that the axiom of choice (an “existence principle”) implies the law of excluded middle (which purports to be a logical principle). As a logical choice principle, epsilon allows us to translate that result to a logical setting, where one can (...) get an analogue of Diaconescu’s result, but also can disentangle the roles of certain other assumptions that are hidden in mathematical presentations. It is our view that these results have not received the attention they deserve: logicians are unlikely to read a discussion because the results considered are “already well known,” while the results are simultaneously unknown to philosophers who do not specialize in what most philosophers will regard as esoteric logics. This is a problem, since these results have important implications for and promise signif i cant illumination of contem- porary debates in metaphysics. The point of this paper is to make the nature of the results clear in a way accessible to philosophers who do not specialize in logic, and in a way that makes clear their implications for contemporary philo- sophical discussions. To make the latter point, we will focus on Dummettian discussions of realism and anti-realism. Keywords: epsilon, axiom of choice, metaphysics, intuitionistic logic, Dummett, realism, antirealism.

Democratic theorists often distinguish between two views of democratic procedures. ‘Outcomes theorists’ emphasize the instrumental nature of these procedures and argue that they are only valuable because they tend to produce good outcomes. In contrast, ‘proceduralists’ emphasize the intrinsic value of democratic procedures, for instance, on the grounds that they are fair. In this paper. I argue that we should reject pure versions of these two theories in favor of an understanding of the democratic ideal that recognizes a commitment to (...) both intrinsically valuable democratic procedures and democratic outcomes. In instances in which there is a conflict between these two commitments, I suggest they must be balanced. This balancing approach offers a justification of judicial review on the grounds that it potentially limits outcomes that undermine democracy. But judicial review is not justifiable in any instance in which a bad democratic outcome results from democratic procedures. When the loss that would result from overturning a democratic procedure is greater than the gain to democracy that would result from ensuring against an undemocratic outcome; judicial review is not justifiable. Loss or gain to democracy is defined by the negative or positive impact of each action on the core democratic values of equality and autonomy, aspects of the democratic ideal. Even when judicial review is justified, the fact that it overturns intrinsically valuable procedures suggests that such review is never ideal from the standpoint of democracy. (shrink)

I argue that the appropriateness of an assertion is sensitive to context—or, really, the “common ground”—in a way that hasn’t previously been emphasized by philosophers. This kind of context-sensitivity explains why some scientific conclusions seem to be appropriately asserted even though they are not known, believed, or justified on the available evidence. I then consider other recent attempts to account for this phenomenon and argue that if they are to be successful, they need to recognize the kind of context-sensitivity that (...) I argue for.

In 1794, Michael Wenzel Voigt, a professor of rhetoric in present-day Czechia, published the first German translation of Aristotle’s De anima. Voigt’s translation was explicitly intended to rescue Aristotle's views on the soul, and the bold strategy he adopts towards this end is to assert a direct connection between Aristotle’s doctrines and Kant’s Critical philosophy. Thus, he contends that Aristotle’s books on the soul can be read as an “appendix” or even as a “propadeutic” to Kant’s Critical works. Despite Voigt’s (...) rather hamfisted attempt to establish this connection, the conjecture at the core of his project—that a number of key Kantian claims about the mind or soul have a largely overlooked Aristotelian provenance—turns out to be correct, or so I argue in this chapter. Even so, we will see that this connection is not direct but is instead mediated by the reception of Aristotle in the late 17th and early 18th century. Moreover, it is not limited to the views Aristotle expresses in his texts on the soul but extends beyond his psychological and even metaphysical works to include views expressed in his logical and ethical thought.

Corey W. Dyck presents a new account of Kant's criticism of the rational investigation of the soul in his monumental Critique of Pure Reason, in light of its eighteenth-century German context. When characterizing the rational psychology that is Kant's target in the Paralogisms of Pure Reason chapter of the Critique commentators typically only refer to an approach to, and an account of, the soul found principally in the thought of Descartes and Leibniz. But Dyck argues that to do so (...) is to overlook the distinctive rational psychology developed by Christian Wolff, which emphasized the empirical foundation of any rational cognition of the soul, and which was widely influential among eighteenth-century German philosophers, including Kant. In this book, Dyck reveals how the received conception of the aim and results of Kant's Paralogisms must be revised in light of a proper understanding of the rational psychology that is the most proximate target of Kant's attack. In particular, he contends that Kant's criticism hinges upon exposing the illusory basis of the rational psychologist's claims inasmuch as he falls prey to the appearance of the soul as being given in inner experience. Moreover, Dyck demonstrates that significant light can be shed on Kant's discussion of the soul's substantiality, simplicity, personality, and existence by considering the Paralogisms in this historical context.Readership: Scholars and advanced students in history of philosophy, especially those working on Kant.

Few of Kant’s doctrines are as difficult to understand as that of self-affection. Its brief career in the published literature consists principally in its unheralded introduction in the Transcendental Aesthetic and unexpected re-appearance at a key moment in the Deduction chapter in the B edition of the first Critique. Kant’s commentators, confronted with the difficulty of this doctrine, have naturally resorted to various strategies of clarification, ranging from distinguishing between empirical and transcendental self-affection, divorcing self-affection from the claims of self-knowledge (...) with which Kant explicitly connects it, and, perhaps least justified of all, ignoring the doctrine altogether. Yet the connection between self-affection and central Critical doctrines (such as the transcendental synthesis of the imagination) marks all of these strategies as last resorts. In this paper, I seek to provide a clearer outline of the constellation of those issues which inform Kant’s discussion of self-affection. More particularly, I intend to explain the crucial role played by self-affection in the account of the transcendental conditions of perception provided late in the B Deduction. (shrink)

Amalia Holst was an important pedagogical theorist and philosopher who was part of the distinctive intellectual milieu of Hamburg in the late 18th and early 19th century. Holst has enjoyed a fair amount of attention from scholars working on the history of feminism, and she has recently come to the attention of historians of philosophy for her incisive critique of (Rousseau-inspired) educational theories, her vocal advocacy for women’s access to higher education, and for apparently radical lines of thinking in her (...) views on history, religion, and morality. While Holst was something of a public figure in Hamburg—she published two controversial treatises in her lifetime, in addition to a lengthy review of a popular novel—there is relatively little known about her life, with most of what we do know owed to only a sparse handful of sources. It is, therefore, a rather significant development for scholars working on Holst that two letters by her should come to light. These letters are replete with new details of Holst’s life, her intellectual network, and they seem to have been wholly unaccounted for by Holst’s biographers. In this article, I will provide a transcription and translation, with annotations, of the two new letters. (shrink)

Climate scientists often apply statistical tools to a set of different estimates generated by an “ensemble” of models. In this paper, I argue that the resulting inferences are justified in the same way as any other statistical inference: what must be demonstrated is that the statistical model that licenses the inferences accurately represents the probabilistic relationship between data and target. This view of statistical practice is appropriately termed “model-based,” and I examine the use of statistics in climate fingerprinting to show (...) how the difficulties that climate scientists encounter in applying statistics to ensemble-generated data are the practical difficulties of normal statistical practice. The upshot is that whether the application of statistics to ensemble-generated data yields trustworthy results should be expected to vary from case to case. (shrink)

In this paper, I consider Baumgarten’s views on the soul in the context of the Pietist critique of Wolff’s rational psychology. My primary aim is to account for the largely unacknowledged differences between Wolff’s and Baumgarten’s rational psychology, though I also hope to show that, in some cases, the Pietists were rather more perceptive in their reading of Wolff than they are typically given credit for as their criticisms frequently succeed in drawing attention to significant omissions in Wolff’s discussion.

In this essay I develop and defend a theory of state punishment within a wider conception of political legitimacy. While many moral theories of punishment focus on what is deserved by criminals, I theorize punishment within the specific context of the state's relationship to its citizens. Central to my account is Rawls's “liberal principle of legitimacy,” which requires that all state coercion be justifiable to all citizens. I extend this idea to the justification of political coercion to criminals qua citizens. (...) I argue that the liberal principle of legitimacy implicitly requires states to respect the basic political rights of those who are guilty of committing crimes, thus prohibiting capital punishment.

Hate groups are often thought to reveal a paradox in liberal thinking. On the one hand, such groups challenge the very foundations of liberal thought, including core values of equality and freedom. On the other hand, these same values underlie the rights such as freedom of expression and association that protect hate groups. Thus a liberal democratic state that extends those protections to such groups in the name of value neutrality and freedom of expression may be thought to be undermining (...) the values on which its legitimacy rests. In this paper, I suggest how this apparent paradox might be resolved. I argue that the state should protect the expression of illiberal beliefs, but that the state (along with its citizens) is also obligated to criticize publicly those beliefs. Distinguishing between two kinds of state action—coercive and expressive—I contend that such criticism should be pursued through the state’s expressive capacities in its roles as speaker, educator, and spender. Here I extend the familiar idea that law, to be legitimate, must be widely publicized; I contend that a proper theory of the freedom of expression obligates the legitimate state to publicize the reasons that underlie rights, in particular reasons that appeal to the entitlement of each citizen subject to coercion to be treated as free and equal. My theory of freedom of expression is thus “expressive” in two senses: it protects the entitlement of citizens to express any political viewpoint, and it emphasizes a role for the state in explaining these free-speech protections and persuading its citizens of the value of the entitlements that underlie them.

Pierre Duhem’s influential argument for holism relies on a view of the role that background theory plays in testing: according to this still common account of “auxiliary hypotheses,” elements of background theory serve as truth-apt premises in arguments for or against a hypothesis. I argue that this view is mistaken. Rather than serving as truth-apt premises in arguments, auxiliary hypotheses are employed as “epistemic tools”: instruments that perform specific tasks in connecting our theoretical questions with the world but that are (...) not premises in arguments. On the resulting picture, the acceptability of an auxiliary hypothesis depends not on its truth but on contextual factors such as the task or purpose it is put to and the other tools employed alongside it.

In this chapter, I consider the largely overlooked influence of E. W. von Tschirnhaus' treatise on method, the Medicina mentis, on Wolff's early philosophical project (in both its conception and execution). As I argue, part of Tschirnhaus' importance for Wolff lies in the use he makes of principles gained from experience as a foundation for the scientific enterprise in the context of his broader philosophical rationalism. I will show that this lesson from Tschirnhaus runs through Wolff's earliest philosophical discussions, and (...) indeed continues to inform his major texts in logic and mathematics just before the publication of the German Metaphysics. In the end, my discussion has the effect of revealing Tschirnhaus to be an exceptionally important influence on Wolff's development, perhaps even as important (or so I suggest) as Leibniz. (shrink)

Legal theorists have characterized physical evidence of brain dysfunction as a double-edged sword, wherein the very quality that reduces the defendant’s responsibility for his transgression could simultaneously increase motivations to punish him by virtue of his apparently increased dangerousness. However, empirical evidence of this pattern has been elusive, perhaps owing to a heavy reliance on singular measures that fail to distinguish between plural, often competing internal motivations for punishment. The present study employed a test of the theorized double-edge pattern using (...) a novel approach designed to separate such motivations. We asked a large sample of participants (N = 330) to render criminal sentencing judgments under varying conditions of the defendant’s mental health status (Healthy, Neurobiological Disorder, Psychological Disorder) and the disorder’s treatability (Treatable, Untreatable). As predicted, neurobiological evidence simultaneously elicited shorter prison sentences (i.e., mitigating) and longer terms of involuntary hospitalization (i.e., aggravating) than equivalent psychological evidence. However, these effects were not well explained by motivations to restore treatable defendants to health or to protect society from dangerous persons but instead by deontological motivations pertaining to the defendant’s level of deservingness and possible obligation to provide medical care. This is the first study of its kind to quantitatively demonstrate the paradoxical effect of neuroscientific trial evidence and raises implications for how such evidence is presented and evaluated.

Considered in light of the reader’s expectation of a thoroughgoing criticism of the pretensions of the rational psychologist, and of the wealth of discussions available in the broader 18th century context, which includes a variety of proofs that do not explicitly turn on the identification of the soul as a simple substance, Kant’s discussion of immortality in the Paralogisms falls lamentably short. However, outside of the Paralogisms (and the published works generally), Kant had much more to say about the arguments (...) for the soul’s immortality as he devoted considerable time to the topic throughout his career in his lectures on metaphysics. In fact, as I show in this paper, the student lecture notes prove to be an indispensable supplement to the treatment in the Paralogisms, not only for illuminating Kant’s criticism of the rational psychologist’s views on the immortality of the soul, but also in reconciling this criticism with Kant’s own positive claims regarding certain theoretical proofs of immortality.

When attempting to capture the concept of enlightenment that underlies and motivates philosophical (and political and scientific) developments in the 18th century, historians of philosophy frequently rely upon a needlessly but intentionally exclusive account. This, namely, is the conception of enlightenment first proposed by Kant in his famous essay of 1784, which takes enlightenment to consist in the “emergence from the self-imposed state of minority” and which is only possible for a “public” to attain as a result of the public (...) use of reason, a privilege enjoyed by citizens and exemplified in the activity of the scholar. That women, among other groups, did not hold the status of citizens and did not enjoy access to the institutions or training that might gain them recognition as scholars is apparently not a concern for Kant, as he notes that the enlightened condition is likely out of reach anyway for “by far the greatest part of humankind (including the entire fair sex)” (AA 8:35). This naturally leads one to wonder what a history of this period could look like when considered from the perspective of a different, more inclusive conception of enlightenment, and in this chapter I propose to conduct an experiment of sorts just along these lines. As opposed to Kant’s exclusionary conception, I will instead take that proposed by his distinguished contemporary, Moses Mendelssohn, as my starting point. In addition to offering a conception of enlightenment distinctive both for its wide scope and progressive character, Mendelssohn’s has the advantage, or so I will show, of bringing the manifold intellectual contributions of a diverse set of women into focus, though it does more than this in that it also reveals these women to actively and critically engage with key aspects of Mendelssohn’s and others’ philosophical views.

Religious freedom is often thought to protect, not only religious practices, but also the underlying religious beliefs of citizens. But what should be said about religious beliefs that oppose religious freedom itself or that deny the concept of equal citizenship? The author argues here that such beliefs, while protected against coercive sanction, are rightly subject to attempts at transformation by the state in its expressive capacities. Transformation is entailed by a commitment to publicizing the reasons and principles that justify the (...) basic rights of citizens. (shrink)

The best and most popular argument for probabilism is the accuracy-dominance argument, which purports to show that alethic considerations alone support the view that an agent’s degrees of belief should always obey the axioms of probability. I argue that extant versions of the accuracy-dominance argument face a problem. In order for the mathematics of the argument to function as advertised, we must assume that every omniscient credence function is classically consistent; there can be no worlds in the set of dominance-relevant (...) worlds that obey some other logic. This restriction cannot be motivated on alethic grounds unless we’re also willing to accept that rationality requires belief in every metaphysical necessity, as the distinction between a priori logical necessities and a posteriori metaphysical ones is not an alethic distinction. To justify the restriction to classically consistent worlds, non-alethic motivation is required. And thus, if there is a version of the accuracy-dominance argument in support of probabilism, it isn’t one that is grounded in alethic considerations alone. (shrink)

While there is good reason to think that Mendelssohn's Morgenstunden targets some of the key claims of Kant’s first Critique, this criticism has yet to be considered in the appropriate context or presented in all of its systematic detail. I show that far from being an isolated assault, Mendelssohn’s attack in the Morgenstunden is a continuation and development of his earlier criticism of Kant’s idealism as presented in the Inaugural Dissertation. I also show that Mendelssohn’s objection was more influential on (...) Kant than has previously been suspected; not only did Kant respond to it in a brief review and a set of remarks published along with a disciple’s examination of Mendelssohn’s text but, as I will suggest, Kant’s Refutation of Idealism is intended (at least in part) to undermine the Cartesian starting-point Mendelssohn had presumed throughout his campaign against Kantian idealism.

In this paper, I argue that there are multiple principles of apperception which jointly constitute the foundation of Kant's argument in the transcendental deduction.

Wilson [Dialectica 63:525–554, 2009], Moore [Int Stud Philos Sci 26:359–380, 2012], and Massin [Br J Philos Sci 68:805–846, 2017] identify an overdetermination problem arising from the principle of composition in Newtonian physics. I argue that the principle of composition is a red herring: what’s really at issue are contrasting metaphysical views about how to interpret the science. One of these views—that real forces are to be tied to physical interactions like pushes and pulls—is a superior guide to real forces than (...) the alternative, which demands that real forces are tied to “realized” accelerations. Not only is the former view employed in the actual construction of Newtonian models, the latter is both unmotivated and inconsistent with the foundations and testing of the science. (shrink)

In this paper, I provide an account of the role of the associative function of the imagination in causal cognition for Kant. I consider, first, Kant’s treatment of the imaginative faculty in the student notes to Kant’s lectures on anthropology in the 1770s, with the aim of working up a more-or-less comprehensive taxonomy of its various sub-faculties. I then turn to Kant’s account of the activity of the imagination, particularly in accordance with the law of association, in the theory of (...) cognition presented in the notes, and show that Kant, apparently in spite of Hume, takes the result of this activity as the basis for causal cognition. I then contend that Kant’s treatment of affinity in the A edition Deduction is animated precisely by his concern to shore up his previous account of causal cognition against Hume’s sceptical challenge.

: Mendelssohn’s Philosophische Gespräche, first published in 1755, represents his first philosophical work in German and rather surprisingly for a debut, in the first two dialogues of that work Mendelssohn attempts nothing less than a defense of the legacy of the most controversial philosopher of his day, Benedict de Spinoza. In this paper, I attempt to enlarge the context, and if possible to raise the stakes, of Mendelssohn’s discussion in order to bring out what I take to be a much (...) more ambitious project on Mendelssohn’s part, namely, not only the rehabilitation of a fellow Jewish thinker but also the rehabilitation of metaphysics as such by means of a thorough accounting of the Spinozan elements in the Wolffian philosophy. As I will show, framing the project of the Gespräche too narrowly is responsible for obscuring much of what I take to be most original and insightful in Mendelssohn’s use and interpretation of Wolff’s thought, as well as his ultimate purpose in resolving what he regarded as an ongoing crisis in metaphysics that is responsible to no small extent for its widespread neglect.

In this paper I consider Tetens' reaction to Kant's Inaugural Dissertation in his two most important philosophical works, the essay “Über die allgemeine speculativische Philosophie” of 1775 and the two-volume Philosophische Versuche of 1777. In particular, I focus on Tetens’ critical discussion of Kant's account of the acquisition of concepts of space and time.

Amalia Holst (1758-1829) has had a rather conflicted reception within the history of feminism. Her Über die Bestimmung des Weibes zur höhern Geistesbildung (On the Vocation of Woman to the Higher Education of the Mind, 1802) is a strident defense of women’s right of access to education; however her case relies on the presuppostion of woman's traditional threefold role as "mother, spouse, and housewife." In this essay, in addition to disclosing new details about Holst's life, I contend that a closer (...) reading of her text reveals a rather more radical project motivating her discussion, and that this helps alleviate concerns about her alleged unoriginality, conservatism, and elitism.

The Thesis of Kant’s Third Antinomy asserts that, because it is “necessary to assume another causality through freedom” in order to derive all the appearances of the world, “causality in accordance with the laws of nature is not the only one” (A444/B472). The argument Kant supplies in support of this, however, has been the subject of interpretative disagreement since at least Schopenhauer, with the most plausible reconstructions being dismissed as question-begging, resting on a conflation relating to the principle of sufficient (...) reason, or attacking a straw-man of the Antithesis position. In this paper, I attempt to provide a novel interpretation of the argument for the Thesis position, one that offers a more compelling case against a charitably interpreted Antithesis position.

The concept of the highest good is an important but hardly uncontroversial piece of Kant’s moral philosophy. In the considerable literature on the topic, challenges are raised concerning its apparently heteronomous role in moral motivation, whether there is a distinct duty to promote it, and more broadly whether it is ultimately to be construed as a theological or merely secular ideal. Yet comparatively little attention has been paid to the context of a doctrine that had enjoyed a place of prominence (...) in the ethical systems of the ancients, where these systems provided a key critical foil for the development of Kant’s own conception of the highest good in terms of “happiness distributed in exact proportion to morality” (cf. 5:110). Indeed, these ethical systems prove important for Kant not only in his initial presentation of his account in the Canon of Pure Reason in the first Critique, where he sought to redress the errors of the Epicurean and Stoic conception in particular, but also and importantly in the course of his development towards the second Critique. As I argue in this paper, Christian Garve’s defense of a revised but recognizably Stoic conception of the highest good in his translation of and commentary on Cicero’s De officiis (On Duties), helps to account for Kant’s renewed attention to that doctrine, and specifically to the errors attending the Stoic version, in the Dialectic of Pure Practical Reason.

Philosophy of science has witnessed substantial recent debate over the existence of a structural analogue of chaos, which is alleged to spell trouble for certain uses of climate models. The debate over the analogy can and should be separated from its alleged epistemic implications: chaos-like behavior is neither necessary nor sufficient for small dynamical misrepresentations to generate erroneous results. The kind of sensitivity that matters in epistemology is one that induces unsafe beliefs, and the existence of a structural analogue to (...) chaos is better seen as an explanation for known safety failures than as providing evidence for unknown ones.

As far as treatments of causation are concerned, the pre-Kantian 18th century German context has long been dismissed as a period of uniform and unrepentant Leibnizian dogmatism. While there is no question that discussions of issues relating to causation in this period inevitably took Leibniz as their point of departure, it is certainly not the case that the resulting positions were in most cases dogmatically, or in some cases even recognizably, Leibnizian. Instead, German theorists explored a range of positions regarding (...) the nature of causal powers, the appropriate systems to explain the observed agreement between the states of substances, and the ground of free actions, or so I will argue in this chapter. Focusing on these three issues, I will here sketch the development of the debates relating to causation and trace the evolution of positions among the philosophers within the so-called Leibnizian-Wolffian philosophy as well as among its many opponents.

A number of theorists have argued that Scanlon's contractualist theory both "gets around" and "solves" the non-identity problem. They argue that it gets around the problem because hypothetical deliberation on general moral principles excludes the considerations that lead to the problem. They argue that it solves the problem because violating a contractualist moral principle in one's treatment of another wrongs that particular other, grounding a person-affecting moral claim. In this paper, I agree with the first claim but note that all (...) it shows is that the act is impersonally wrong. I then dispute the second claim. On Scanlon's contractualist view, one wrongs a particular other if one treats the other in a way that is unjustifiable to that other on reasons she could not reasonably reject. We should think of person-affecting wronging in terms of the reasons had by the actual agent and the actual person affected by the agent's action. In non-identity cases, interpersonal justifiability is therefore shaped both by the reason to reject the treatment provided by the bad suffered and the reason to affirm the treatment provided by the goods had as a result of existing. I argue it would be reasonable for the actual person to find the treatment justifiable, and so I conclude that Scanlon's contractualist metaethics does not provide a narrow person-affecting solution to the non-identity problem on its own terms. I conclude that the two claims represent a tension within Scanlon's contractualist theory itself. (shrink)

Kant's A-Edition objective deduction is naturally (and has traditionally been) divided into two arguments: an " argument from above" and one that proceeds " von unten auf." This would suggest a picture of Kant's procedure in the objective deduction as first descending and ascending the same ladder, the better, perhaps, to test its durability or to thoroughly convince the reader of its soundness. There are obvious obstacles to such a reading, however; and in this chapter I will argue that the (...) arguments from above and below constitute different, albeit importantly inter-related, proofs. Rather than drawing on the differences in their premises, however, I will highlight what I take to be the different concerns addressed and, correspondingly, the distinct conclusions reached by each. In particular, I will show that both arguments can be understood to address distinct specters, with the argument from above addressing an internal concern generated by Kant’s own transcendental idealism, and the argument from below seeking to dispel a more traditional, broadly Humean challenge to the understanding’s role in experience. These distinct concerns also imply that these arguments yield distinct conclusions, though I will show that they are in fact complementary. (shrink)

In this paper, I consider the basis for Kant's praise of Wolff's general logic as "the best we have." I argue that Wolff's logic was highly esteemed by Kant on account of its novel analysis of the three operations of the mind (tres operationes mentis), in the course of which Wolff formulates an argument for the priority of the understanding's activity of judging.

In this paper, I attempt to trace the broader contours of a putative Leibnizian psychology by adopting the rather unusual, and perhaps historically dubious, strategy of outlining the continuities between Leibniz’s discussion of the soul and the much more detailed and systematic psychological writings of his German successor, Christian Wolff.

Despite Marx’s claim that criticism against his views from a religious standpoint are not deserving of serious examination, I try to offer a critical examination of Marx’s epistemology of religion from the viewpoint of Reformed epistemology. Although Marx himself never set forth a systematic epistemology, let alone an epistemology of religion, his writings nonetheless provide an adequate resource to reconstruct his views on the matter. Given this, I set out what I take to be characteristic of Marx’s epistemology of religion (...) and provide the meta-context in which the epistemological issue is framed. In light of Reformed epistemology, I then provide a critique of Marx’s criticism by turning his own argument on its head to the effect that there is significant likelihood that his view is both false and irrational. Finally, I defend against a possible objection. (shrink)

Meier’s Gedancken von dem Zustande der Seele nach dem Tode (Gedancken) deserves a prominent place among treatments of the immortality of the soul in 18th century German philosophy, both within and without the Wolffian tradition of rational psychology. It does not wilt next to Mendelssohn’s Phädon in its quality of expression, and might even be compared with Kant’s discussion in the Paralogisms chapter of his Kritik der reinen Vernunft in terms of the boldness of its argument and its philosophical rigour. (...) The Gedancken contributed greatly to Meier’s growing reputation as an original thinker and helped him emerge from the shadow of his famous colleague in the philosophy faculty at the Friedrichs-Universität in Halle, Christian Wolff; moreover, it provoked detailed responses on the part of its critics and even made Meier himself the subject of official investigation as an accused aider and abettor of freethinkers. Meier’s Gedancken thus stands as a work of central importance within his own philosophical corpus and in the history of 18th century German rational psychology more generally. Accordingly, in this Introductory Essay, I will present the context and argument, as well as the reception, of the Gedancken, and then consider Meier’s subsequent defense of his controversial text.

Early Modern German Philosophy (1690-1750) makes some of the key texts of early German thought available in English, in most cases for the first time. The translations range from texts by the most important figures of the period, including Christian Thomasius, Christian Wolff, Christian August Crusius, and Georg Friedrich Meier, as well as texts by consequential but less familiar thinkers such as Dorothea Christiane Erxleben, Theodor Ludwig Lau, Friedrich Wilhelm Stosch, and Joachim Lange. The topics covered range across a number (...) of areas of theoretical philosophy, including metaphysics (the immortality of the soul, materialism and its refutation, the pre-established harmony), epistemology (the principle of sufficient reason, the limits of reason with respect to matters of faith), and logic (the role of prejudices in cognition and the doctrine of truth).

This article argues that if panpsychism is true, then there are grounds for thinking that digitally-based artificial intelligence may be incapable of having coherent macrophenomenal conscious experiences. Section 1 briefly surveys research indicating that neural function and phenomenal consciousness may be both analog in nature. We show that physical and phenomenal magnitudes—such as rates of neural firing and the phenomenally experienced loudness of sounds—appear to covary monotonically with the physical stimuli they represent, forming the basis for an analog relationship between (...) the three. Section 2 then argues that if this is true and micropsychism—the panpsychist view that phenomenal consciousness or its precursors exist at a microphysical level of reality—is also true, then human brains must somehow manipulate fundamental microphysical-phenomenal magnitudes in an analog manner that renders them phenomenally coherent at a macro level. However, Sect. 3 argues that because digital computation abstracts away from microphysical-phenomenal magnitudes—representing cognitive functions non-monotonically in terms of digits—digital computation may be inherently incapable of realizing coherent macroconscious experience. Thus, if panpsychism is true, digital AI may be incapable of achieving phenomenal coherence. Finally, Sect. 4 briefly examines our argument’s implications for Tononi’s Integrated Information Theory theory of consciousness, which we contend may need to be supplanted by a theory of macroconsciousness as analog microphysical-phenomenal information integration.

This document gathers together, in summary form, objections scattered across many papers and multiple online databases. Nevertheless, it omits some objections, notably complicated ones.

This document briefly summarizes several objections to Thomas Kuhn on science, including by Feyerabend, Davidson, and Fodor.

Imprecise probabilities are often modelled with representors, or sets of probability functions. In the recent literature, two ways of interpreting representors have emerged as especially prominent: vagueness interpretations, according to which each probability function in the set represents how the agent's beliefs would be if any vagueness were precisified away; and comparativist interpretations, according to which the set represents those comparative confidence relations that are common to all probability functions therein. I argue that these interpretations have some important limitations. I (...) also propose an alternative—the functional interpretation—according to which representors are best interpreted by reference to the roles they play in the theories that make use of them.

In this paper, I draw attention to a revolution in the metaphysical commitments of Western astrology. Although I do not wish to promote astrology, I propose a rational route to this revolution. But there is a strong argument, from a Popperian perspective, that my proposal fails to establish rationality. I then consider whether we should say that astrology is either false or unfalsifiable, drawing attention to some surprising findings from schizophrenia research. Also, in a footnote I present “Tompkins’ paradox.”.

In his Edifying Discourses, Soren Kierkegaard published a sermon entitled ‘The Unchangeableness of God’ in which he reiterated the dogma which dominated Catholic, Protestant and even Jewish expressions of classical supernaturalist theology from the first century A.D. until the advent of process theology in the twentieth century. The dogma that as a perfect being, God must be totally unchanging in every conceivable respect was expressed by Kierkegaard in such ways as: He changes all, Himself unchanged. When everything seems stable and (...) in the overturn of all things, He remains equally unchanged; no change touches Him, not even the shadow of a change; in unaltered clearness He, the father of lights, remained eternally unchanged. 1.

Moral naturalists are often said to have trouble making sense of inter-communal moral disagreements. The culprit is typically thought to be the naturalist’s metasemantics and its implications for the sameness of meaning across communities. The most familiar incarnation of this metasemantic challenge is the Moral Twin Earth argument. We address the challenge from the perspective of analytic naturalism and argue that making sense of inter-communal moral disagreement creates no special issues for this view.

Various tribes deny that pregnancy is caused by sexual relations. Is this irrational? I present a puzzle involving testimony which some tribes might once have faced.

The use of brain scanning now dominates the cognitive sciences, but important questions remain to be answered about what, exactly, scanning can tell us. One corner of cognitive science that has been transformed by the use of neuroimaging, and that a scanning enthusiast might point to as proof of scanning's importance, is the study of face perception. Against this view, we argue that the use of scanning has, in fact, told us rather little about the information processing underlying face perception (...) and that it is not likely to tell us much more.
