Frege-Geach worries about embedding and composition have plagued metaethical theories like emotivism, prescriptivism and expressivism. The sharpened point of such criticism has come to focus on whether negation and inconsistency have to be understood in descriptivist terms. Because they reject descriptivism, these theories must offer a non-standard account of the meanings of ethical and normative sentences as well as related semantic facts, such as why certain sentences are inconsistent with each other. This paper fills out such a solution to the (...) negation problems, following some of the original emotivist ideas about the interplay of interests in conversation. We communicate both to share information and coordinate our actions, and we use distinctively normative language like deontic ‘must’ and ‘may’ to negotiate what people are to do. The kinds of disagreement involved in such negotiation can illuminate the issues with negation and inconsistency. This paper outlines a dynamic semantic system in which these ideas can bear fruit, developing the scorekeeping model of conversation. The result is clarification about what Frege-Geach worries can mean for nondescriptive semantics. (shrink)

Each person has a special relation to his or her own well-being. This rough thought, which can be sharpened in different ways, is supposed to substantially count against objectivist theories on which one can intrinsically benefit from, or be harmed by, factors that are independent of one’s desires, beliefs, and other attitudes. It is often claimed, contra objectivism, that one cannot be _alienated_ from one’s own interests, or that improvements in a person’s well-being must _resonate_ with that person. However, I (...) argue that every theory of well-being must allow that we can be alienated from our own well-being, and that sophisticated objectivists can accept and make use of a resonance constraint against their opponents.

A critical review of Michael Ridge's book Impassioned Belief.

This paper argues that phenomenal consciousness is what makes an entity a welfare subject. I develop a variety of motivations for this view, and then defend it from objections concerning death, non-conscious entities that have interests (such as plants), and conscious entities that necessarily have welfare level zero. I also explain how my theory of welfare subjects relates to experientialist and anti-experientialist theories of welfare goods.

While more species are being identified as cultural on a regular basis, stark differences between human and animal cultures remain. Humans are more richly cultural, with group-specific practices and social norms guiding almost every element of our lives. Furthermore, human culture is seen as cumulative, cooperative, and normative, in contrast to animal cultures. One hypothesis to explain these differences is grounded in the observation that human children across cultures appear to spontaneously over-imitate silly or causally irrelevant behaviors that they observe. (...) The few studies on over-imitation in other species are largely taken as evidence that spontaneous over-imitation is not present in other species. This leads to the over-imitation hypothesis – that the differences between human culture and animal cultures can be traced to the human unique tendency to over-imitate. In this paper, we analyze the current state of the literature on animal over-imitation and challenge the adequacy of the over-imitation hypothesis for the differences between humans and animal cultures. To make this argument, we first argue that the function of human over-imitation is norm-learning and that over-imitation, like skill-learning, should be subject to selective social learning effects. Then we review the empirical evidence against animal over-imitation and argue that these studies do not take into account the relevant variables given the normative and selective nature of over-imitation. We then analyze positive empirical evidence of over-imitation in great apes and canids from the experimental literature and conclude that the current body of evidence suggests that some canids and primates may have the capacity for over-imitation. This paper offers a methodological suggestion for how to study animal over-imitation, and a theoretical suggestion that over-imitation might be much more widely found among species. The larger implication for claims about human uniqueness suggests that if we do find widespread evidence of over-imitation across species, many of the current theories of human uniqueness that focus on human hyper-cooperation or social norms may have only identified a difference of degree, not of kind, between humans and other animals.

I develop and defend a sense-datum theory of perception. My theory follows the spirit of classic sense-datum theories: I argue that what it is to have a perceptual experience is to be acquainted with some sense-data, where sense-data are private particulars that have all the properties they appear to have, that are common to both perception and hallucination, that constitute the phenomenal characters of perceptual experiences, and that may be aptly described as pictures in-side one’s head. But my theory also (...) diverges from conventional sense-datum theories in some key respects: on my view, (1) sense-data are first-person presentations of neural states, (2) the sensational qualities of sense-data differ in kind from the sensible qualities of external objects, and (3) sense-data are the vehicles in virtue of which we perceive, rather than the objects that we perceive. I argue that this package of claims is appropriately labeled ‘sense-datum theory’, and that the resultant view ought to be a live contender in contemporary philosophy of perception. (shrink)

Super-Humeans argue that the most parsimonious ontology of the natural world compatible with our best physical theories consists exclusively of particles and the distance relations between them. This paper argues by contrast that Super-Humean reduction goes insufficiently far, by showing there to be a more parsimonious ontology compatible with physics: Ultimate-Humeanism. This novel view posits an ontology consisting solely of the particles and distance relations required for the existence of a single brain. Super-Humeans impose conditions on what counts as an (...) ontology of the natural world to avoid their view slipping into this kind of ontology, but these conditions are arbitrarily imposed and once this is exposed, Super-Humeans face a dilemma. Either they can embrace Ultimate-Humeanism as the minimal ontology of the natural world compatible with physics, or (more likely) they can rethink the methodology that got them there. Overall, this paper argues that Super-Humeanism currently lacks principled motivation, outlines a framework for naturalistic ontological reductions, and exposes the consequences of unchecked adherence to a simplicity-driven methodology.

While many aspects of cognition have been shown to be shared between humans and non-human animals, there remains controversy regarding whether the capacity to mentally time travel is a uniquely human one. In this paper, we argue that there are four ways of representing when some event happened: four kinds of temporal representation. Distinguishing these four kinds of temporal representation has five benefits. First, it puts us in a position to determine the particular benefits these distinct temporal representations afford an (...) organism. Second, it provides the conceptual resources to foster a discussion about which of these representations is necessary for an organism to count as having the capacity to mentally time travel. Third, it enables us to distinguish stricter from more liberal views of mental time travel that differ regarding which kind(s) of temporal representation is taken to be necessary for mental time travel. Fourth, it allows us to determine the benefits of taking a stricter or more liberal view of mental time travel. Finally, it ensures that disagreement about whether some species can mentally time travel is not merely the product of unrecognised disagreement about which temporal representation is necessary for mental time travel. We argue for a more liberal view, on the grounds that it allows us to view mental time travel as an evolutionarily continuous phenomenon, and to recognise that differences in the ways that organisms mentally time travel might reflect different temporal representations, or combinations thereof, that they employ. Our ultimate aim, however, is to create the conceptual framework for further discussion regarding what sorts of temporal representations are required for mental time travel. (shrink)

Empirical evidence suggests that a majority of people believe that time robustly passes, and that many also report that it seems to them, in experience, as though time robustly passes. Non-dynamists deny that time robustly passes, and many contemporary non-dynamists—deflationists—even deny that it seems to us as though time robustly passes. Non-dynamists, then, face the dual challenge of explaining why people have such beliefs and make such reports about their experiences. Several philosophers have suggested the stable-self explanation, according to which (...) what partly explains one or both of the explananda is that people believe themselves to have a stable persisting self which is imagined either as moving through time, or as being stationary, with time moving around it. This paper empirically investigates this explanation. We found, however, no evidential support for the stable-self explanation, leaving the non-dynamist but also, we will argue, the dynamist, with an extant explanatory challenge. (shrink)

Here I offer a critical evaluation of modalism about essential properties. To that effect, I begin by rehearsing Fine’s now infamous counterexamples to pure modalism. I then consider two recent defenses of it, offered by Livingstone-Banks and Cowling, respectively. I argue that both defenses fail. Next I consider the most plausible variety of impure modalism – sparse modalism – which has recently been defended by Wildman and de Melo. Skiles has argued that sparse modalism fails too. I argue that Skiles’s (...) counterexamples misfire; nonetheless, his conclusion that, like pure modalism, sparse modalism is too broad, is on the right track. And so, I offer an original objection – the sparse modal propria counterexample – to show that this is so. I conclude by considering ways the modalist might once again modify her account to circumvent this new objection and improve the account’s extensional adequacy. (shrink)

It is important to note that certain mental health disorders are classified as rare conditions, and they have their own ‘cultural concepts of distress’ as defined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM 5). Cultural concepts of distress are a recent attempt to understand psychological distress influenced by culture, separate from biomedical diagnoses that require equal attention and support for individuals and their families, both physically and emotionally.

In recent years, the science and the philosophy of consciousness has seen growing interest in structural questions about consciousness. This is the Editorial Introduction for a special volume for Philosophy and the Mind Sciences on “Structuralism in Consciousness Studies.”.

Our reasons for emotions such as sadness, anger, resentment, and guilt often remain long after we cease experiencing these emotions. This is puzzling. If the reasons for these emotions persist, why do the emotions not persist? Does this constitute a failure to properly respond to our reasons? In this paper we provide a solution to this puzzle. Our solution turns on the close connection between the rationality of emotion and the rationality of attention, together with the differing reasons to which (...) attention and emotion are properly responsive.

Philosophers have long noted, and empirical psychology has lately confirmed, that most people are “biased toward the future”: we prefer to have positive experiences in the future, and negative experiences in the past. At least two explanations have been offered for this bias: belief in temporal passage and the practical irrelevance of the past resulting from our inability to influence past events. We set out to test the latter explanation. In a large survey, we find that participants exhibit significantly less (...) future bias when asked to consider scenarios where they can affect their own past experiences. This supports the “practical irrelevance” explanation of future bias. It also suggests that future bias is not an inflexible preference hardwired by evolution, but results from a more general disposition to “accept the things we cannot change”. However, participants still exhibited substantial future bias in scenarios in which they could affect the past, leaving room for complementary explanations. Beyond the main finding, our results also indicate that future bias is stake-sensitive and that participants endorse the normative correctness of their future-biased preferences and choices. In combination, these results shed light on philosophical debates over the rationality of future bias, suggesting that it may be a rational response to empirical realities rather than a brute, arational disposition.

This paper outlines a new pluralistic theory of normative reasons for belief, welfarist pluralism, which aims to explain how there can be basic alethic/epistemic reasons for belief and basic pragmatic/non-alethic reasons for belief that can combine to determine what one ought to believe. The paper shows how this non-derivative first-order pluralism arises from a purely welfarist account of the foundations of theoretical normativity, thereby combining foundational pragmatism with non-derivative pluralism about normative reasons for belief. In addition, this paper outlines how (...) welfarist pluralism provides a new and potentialy attractive account of the value of truth (or its indicators), namely that the value of truth (or its indicators) is its direct contribution to individuals' personal good or wellbeing.

Deflationists hold that it does not seem to us, in experience, as though time robustly passes. There is some recent empirical evidence that appears to support this contention. Equally, empirical evidence suggests that we naïvely represent time as dynamical. Thus deflationists are faced with an explanatory burden. If, as they maintain, the world seems to us in experience as though it is non-dynamical, then why do we represent time as dynamical? This paper takes up the challenge of investigating, on the (...) part of the deflationist, one candidate explanation. We hypothesise that people’s belief that the future is what we call deliberatively open partly explains why they represent time as dynamical. In a series of two experiments we test this hypothesis. We find no evidence that beliefs about deliberative openness explain why people represent time as dynamical. Hence there remains an explanatory burden for the deflationist to discharge. (shrink)

It was presented for a session on productivity, process, and the value of making, organised by the Vienna Contemporary Art Space.

Suppose Molinism is true and God placed Adam in the garden because God knew Adam would freely eat of the fruit. Suppose further that, had it not been true that Adam would freely eat of the fruit, were he placed in the garden, God would have placed someone else there instead. When Adam freely eats of the fruit, is he free to do otherwise? This paper argues that there is a strong case for both a positive and a negative answer. (...) Assuming such cases are possible under Molinism, we are left with a puzzling question: if Molinism is true, what can you do? (shrink)

Most work in Kant’s epistemology focuses on what happens “upstream” from experience, prior to the formation of conscious propositional attitudes. By contrast, this essay focuses on what happens "downstream": the formation of assent (Fuerwahrhalten) in its various modes. The mode of assent that Kant calls "Belief" (Glaube) is the main topic: not only moral Belief but also "pragmatic" and "doctrinal" Belief as well. I argue that Kant’s discussion shows that we should reject standard accounts of the extent to which theoretical (...) reason can provide justified assent about things-in-themselves, in favor of one that is much more liberal. Interpretive benefits are not the only results of the discussion, however. I also hope it will become clear along the way that there is such a thing as Kantian Belief, and that we often have quite a lot of it. -/- . (shrink)

It has widely been assumed, by philosophers, that most people unambiguously have a phenomenology as of time passing, and that this is a datum that philosophical theories must accommodate. Moreover, it has been assumed that the greater the extent to which people have said phenomenology, the more likely they are to endorse a dynamical theory of time. This paper is the first to empirically test these assumptions. Surprisingly, our results do not support either assumption. One experiment instead found the reverse (...) correlation: people were more likely to report having passage phenomenology if they endorsed a non-dynamical theory of time. Given that people do not have an unambiguous phenomenology as of time passing, we conclude that this is suggestive evidence in favor of veridical non-dynamism—the view that our phenomenology is veridical, and that it does not unambiguously represent that time passes. Instead, our phenomenology veridically has some quite different content. (shrink)

In this chapter, we argue that a distinct concept of “aesthetic hope” emerges from the way Kierkegaard’s Aesthete treats hope [Haab] and its relationship to recollection [Erindring] in “The Unhappiest One” and “Rotation of Crops.” We first show that aesthetic hope is distinct from the two other kinds of hope discussed by Kierkegaard: temporal hope and eternal hope. We then consider the suggestion that aesthetic hope is also an expression of despair – an inverse hope against hope, which seeks to (...) avoid disappointment by hoping for things that are in some sense certain. The aesthete’s recommendation that we hope in such a way illuminates Kierkegaard’s view of the “dialectic” of temporal hope and eternal hope. Finally, we explore the treatment of hope in Either/Or as essentially involving a controlled, attentional element that anticipates some contemporary trends in the philosophy of hope. (shrink)

In this paper, I argue that David Lewis’s possible world semantics for counterfactual discourse and for fictional discourse are apparently inconsistent and in need of revision. The problem emerges for Lewis’s account once one considers how to evaluate ambifictional counterfactuals. Since this is likely not a concept familiar to most, and since it does not appear that the problem has been previously recognized in the critical literature, I will begin by rehearsing Lewis’s possible worlds semantics for counterfactuals and fiction. Then (...) I will explicate the distinction between intrafictional, extrafictional, interfictional, and ambifictional propositions. Next, I will state what an ambifictional counterfactual proposition is, and explain why this kind of discourse confounds Lewis’s system. I will conclude, finally, with a brief discussion of how the Lewisian would be best advised to resolve the paradox. (shrink)

In this paper I look at the much-discussed case of disabled parents seeking to conceive disabled children. I argue that the permissibility of selecting for disability does not depend on the precise impact the disability will have on the child’s wellbeing. I then turn to an alternative analysis, which argues that the permissibility of selecting for disability depends on the impact that disability will have on the child’s future opportunities. Nearly all bioethicists who have approached the issue in this way (...) have argued that disabilities like deafness unacceptably constrain a child’s opportunities. I argue, however, that this conclusion is premature for several reasons. Most importantly, we don’t have a good way of comparing opportunity sets. Thus, we can’t conclude that deaf children will grow up to have a constrained set of opportunities relative to hearing children. I conclude by suggesting that bioethicists and philosophers of disability need to spend more time thinking carefully about the relationship between disability and opportunity. (shrink)

In this article I discuss the moral-coherence reading of Kant’s moral argument offered by Allen Wood in his recent book _Kant and Religion_, display some of the challenges that it faces and suggest that a moral-psychological formulation is preferable.

This paper argues that the theory of structured propositions is not undermined by the Russell-Myhill paradox. I develop a theory of structured propositions in which the Russell-Myhill paradox doesn't arise: the theory does not involve ramification or compromises to the underlying logic, but rather rejects common assumptions, encoded in the notation of the $\lambda$-calculus, about what properties and relations can be built. I argue that the structuralist had independent reasons to reject these underlying assumptions. The theory is given both a (...) diagrammatic representation, and a logical representation in a novel language. In the latter half of the paper I turn to some technical questions concerning the treatment of quantification, and demonstrate various equivalences between the diagrammatic and logical representations, and a fragment of the $\lambda$-calculus.

Contemporary philosophical debates surrounding toleration have revolved around three issues: What is toleration? Should we tolerate and, if so, why? What should be tolerated? These questions are of central importance to social and political thought.

In this paper we argue that knowledge is characteristically safe true belief. We argue that an adequate approach to epistemic luck must not be indexed to methods of belief formation, but rather to explanations for belief. This shift is problematic for several prominent approaches to the theory of knowledge, including virtue reliabilism and proper functionalism (as normally conceived). The view that knowledge is characteristically safe true belief is better able to accommodate the shift in question.

People are ‘biased toward the future’: all else being equal, we typically prefer to have positive experiences in the future, and negative experiences in the past. Several explanations have been suggested for this pattern of preferences. Adjudicating among these explanations can, among other things, shed light on the rationality of future-bias: For instance, if our preferences are explained by unjustified beliefs or an illusory phenomenology, we might conclude that they are irrational. This paper investigates one hypothesis, according to which future-bias (...) is explained by our having a phenomenology that we describe, or conceive of, as being as of time robustly passing. We empirically tested this hypothesis and found no evidence in its favour. Our results present a puzzle, however, when compared with the results of an earlier study. We conclude that although robust passage phenomenology on its own probably does not explain future-bias, having this phenomenology and taking it to be veridical may contribute to future-bias.

In his recent book, Bernecker (Memory, 2010) has attacked the following prominent view: (RK) S remembers that p only if S knows that p. An attack on RK is also an attack on Timothy Williamson’s view that knowledge is the most general factive stative attitude. In this paper, I defend RK against Bernecker’s attacks and also advance new arguments in favor of it. In Sect. 2, I provide some background on memory. In Sect 3, I respond to Bernecker’s attacks on (...) RK and develop a new argument for RK. In Sects. 4 and 5, I develop two more new arguments for RK. (shrink)

Is a human more conscious than an octopus? In the science of consciousness, it’s oftentimes assumed that some creatures (or mental states) are more conscious than others. But in recent years, a number of philosophers have argued that the notion of degrees of consciousness is conceptually confused. This paper (1) argues that the most prominent objections to degrees of consciousness are unsustainable, (2) examines the semantics of ‘more conscious than’ expressions, (3) develops an analysis of what it is for a (...) degreed property to count as degrees of consciousness, and (4) applies the analysis to various theories of consciousness. I argue that whether consciousness comes in degrees ultimately depends on which theory of consciousness turns out to be correct. But I also argue that most theories of consciousness entail that consciousness comes in degrees. (shrink)

In this paper, I present counterexamples to the evidence thesis, the thesis that S knows that p at t only if S believes that p on the basis of evidence at t. The outline of my paper is as follows. In section 1, I explain the evidence thesis and make clear what a successful counterexample to the evidence thesis will look like. In section 2, I show that instances of non-occurrent knowledge are counterexamples to the evidence thesis. At the end (...) of section 2, I consider the primary thesis of my paper — that the evidence thesis is false — to be successfully defended. In section 3, I consider three variations of the evidence thesis. The first variation restricts the evidence thesis to occurrent knowledge; the second requires for knowledge that one’s belief could be based on evidence; and the third requires for knowledge that the belief was based on evidence at a suitable prior time. The secondary thesis of this paper is that these variations are also subject to serious objections. (shrink)

Both Philip and Andrew are philosophy students whose interests converge around the philosophy of technology broadly understood.

While the two perspectives might not seem that close, there is certain to be an overlap in Andrew and Philip's shared understanding of how technological phenomena play (...) a crucial role concerning religion and society.

Recent research (Latham, Miller and Norton, forthcoming) reveals that a majority of people represent actual time as dynamical. But do they, as suggested by McTaggart and Gödel, represent time as essentially dynamical? This paper distinguishes three interrelated questions. We ask (a) whether the folk representation of time is sensitive or insensitive: i.e., does what satisfies the folk representation of time in counterfactual worlds depend on what satisfies it actually—sensitive—or does is not depend on what satisfies it actually—insensitive, and (b) do (...) those who represent actual time as dynamical, represent time in all possible worlds as dynamical—what we call insensitive dynamism—or do they represent time in all possible worlds as dynamical only conditional on the actual world in fact being dynamical—what we call sensitive dynamism and (c) do dynamists and non-dynamists deploy two different representations of time, or deploy the same representation, but disagree about what actually satisfies that representation? We found no evidence that the folk representation of time is sensitive, or that the folk representation of time is essentially dynamical in either sense, though we did find evidence of a shared representation, on which dynamical features are sufficient, but not necessary, for time.

Most elpistologists now agree that hope for a specific outcome involves more than just desire plus the presupposition that the outcome is possible. This paper argues that the additional element of hope is a disposition to focus on the desired outcome in a certain way. I first survey the debate about the nature of hope in the recent literature, offer objections to some important competing accounts, and describe and defend the view that hope involves a kind of focus or attention. (...) I then suggest that this account makes sense of the intuitive thought that there are moral and pragmatic norms on hope that go beyond the norms on desires and modal presuppositions. I conclude by considering some key questions. (shrink)

This paper develops a theory of analog representation. We first argue that the mark of the analog is to be found in the nature of a representational system’s interpretation function, rather than in its vehicles or contents alone. We then develop the rulebound structure theory of analog representation, according to which analog systems are those that use interpretive rules to map syntactic structural features onto semantic structural features. The theory involves three degree-theoretic measures that capture three independent ways in which (...) a system can be more or less analog. We explain how our theory improves upon prior accounts of analog representation, provides plausible diagnoses for novel challenge cases, extends to hybrid systems that are partially analog and partially symbolic, and accounts for some of the advantages and disadvantages of representing analogically versus symbolically.

Dasgupta poses a serious challenge to realism about natural properties. He argues that there is no acceptable explanation of why natural properties deserve the value realists assign to them and are consequently absent of value. In response, this paper defines and defends an alternative non-explanatory account of normativity compatible with realism. Unlike Lewis and Sider, who believe it is sufficient to defend realism solely on realist terms, I engage with the challenge on unfriendly grounds by revealing a tu quoque. Dasgupta (...) and anti-realists face a similar challenge to that directed against realism: one that not only undermines the objection to realism by legitimising non-explanatory normativity but leaves them facing a significant dilemma.

The aim of the Analytic of Concepts is to derive and deduce a set of pure concepts of the understanding, the categories, which play a central role in Kant’s explanation of the possibility of synthetic a priori cognition and judgment. This chapter is structured around two questions. First, what is a pure concept of the understanding? Second, what is involved in a deduction of a pure concept of the understanding? In answering the first, we focus on how the categories differ (...) from the pure forms of sensibility and examine whether they are known only to be the pure forms of human thinking or rather the forms of discursive cognition as such. In answering the second, we draw a distinction between the application and the exemplification of the categories and use it to identify different ways of understanding Kant’s project in the Transcendental Deduction of the Categories. These questions connect because the answer to the first determines how we should understand the kind of entitlement which is to be established in the Deduction. (shrink)

An increasing amount of twenty-first century metaphysics is couched in explicitly hyperintensional terms. A prerequisite of hyperintensional metaphysics is that reality itself be hyperintensional: at the metaphysical level, propositions, properties, operators, and other elements of the type hierarchy, must be more fine-grained than functions from possible worlds to extensions. In this paper I develop, in the setting of type theory, a general framework for reasoning about the granularity of propositions and properties. The theory takes as primitive the notion of a (...) substitution on a proposition (property, etc.) and, among other things, uses this idea to elucidate a number of theoretically important distinctions. A class of structures are identified which can be used to model a wide range of positions about the granularity of reality; certain of these structures are seen to receive a natural treatment in the category of M-sets.

Formal logic has often been seen as uniquely placed to analyze mathematical argumentation. While formal logic is certainly necessary for a complete understanding of mathematical practice, it is not sufficient. Important aspects of mathematical reasoning closely resemble patterns of reasoning in nonmathematical domains. Hence the tools developed to understand informal reasoning, collectively known as argumentation theory, are also applicable to much mathematical argumentation. This chapter investigates some of the details of that application. Consideration is given to the many contrasting meanings (...) of the word “argument”; to some of the specific argumentation-theoretic tools that have been applied to mathematics, notably Toulmin layouts and argumentation schemes; to some of the different ways that argumentation is implicated in mathematical practices; and to the social aspects of mathematical argumentation.

Kant’s “primacy of the practical” doctrine says that we can form morally justified commitments regarding what exists, even in the absence of sufficient epistemic grounds. In this paper I critically examine three different varieties of Kant’s “moral proof” that can be found in the critical works. My claim is that the third variety—the “moral-psychological argument” based in the need to sustain moral hope and avoid demoralization—has some intriguing advantages over the other two. It starts with a premise that more clearly (...) coheres with Kant’s mature account of moral motivation, and it invokes plausible empirical-psychological theses to motivate a commitment to the full-blown classical deity—the result Kant clearly wanted. From the point of view of its structure, I think this third variety of moral argument also has the most by way of contemporary interest. (shrink)

This paper develops an interpretation of what is essential to kant's doctrine of the highest good, Which defends it while also explaining why it is often rejected. While it is commonly viewed as a theological ideal in which happiness is proportioned to virtue, The paper gives an account in which neither feature appears. The highest good is best understood as a state of affairs to be achieved through human agency, Containing the moral perfection of all individuals and the satisfaction of (...) their permissible ends-I.E., One in which all act from the moral law and in doing so achieve their intended ends. The paper shows that the texts contain two distinct conceptions not distinguished by kant-Both a theological and a secular (political) notion. The standard objections apply to the theological, But the secular conception is consistent with kant's conception of moral conduct. Moreover, That the highest good is introduced as an end to be constructed out of the moral law indicates that the secular version is the essential notion. (shrink)

An essay on Kant's theory of justification, where by “justification” is meant the evaluative concept that specifies conditions under which a propositional attitude is rationally acceptable with a moderate-to-high degree of confidence. Kant employs both epistemic and non-epistemic concepts of justification: an epistemic concept of justification sets out conditions under which a propositional attitude is rationally acceptable with a moderate-to-high degree of confidence and a candidate (if true and Gettier-immune) for knowledge. A non-epistemic concept of justification, by contrast, sets out (...) conditions under which attitudes are rationally acceptable with a moderate-to-high degree of confidence but not candidates for knowledge (even if true). The latter conditions will typically be “pragmatic” or “practical,” and thus license acceptance from a “practical” point of view. For Kant, only broadly-speaking practical reasons can provide adequate motivation for adopting a positive attitude towards a proposition (rather than suspending judgment) in the absence of sufficient epistemic grounds. -/- .

Kant's speculative theistic proof rests on a distinction between “logical” and “real” modality that he developed very early in the pre-critical period. The only way to explain facts about real possibility, according to Kant, is to appeal to the properties of a unique, necessary, and “most real” being. Here I reconstruct the proof in its historical context, focusing on the role played by the theory of modality both in motivating the argument (in the pre-critical period) and, ultimately, in undoing it (...) as a source of knowledge of God's existence (in the critical period). Along the way I examine Kant's version of the now-popular “actualist” thesis that facts about what is possible must be explained by facts about what is actual. I conclude by discussing why the critical Kant claims both that there are rational grounds for accepting the conclusion of his theistic proof, and that such acceptance can not count as knowledge. This is important, I argue, because the same considerations ultimately motivate his prohibition on knowledge of things-in-themselves generally. -/- . (shrink)
