THE MODAL ARGUMENT FOR A PRIORI JUSTIFICATION

Kant famously argued that, from experience, we can only learn how something actually is, but not that it must be so. In this paper, I defend an improved version of Kant's argument for the existence of a priori knowledge, the Modal Argument , against recent objections by Casullo and Kitcher. For the sake of the argument, I concede Casullo's claim that we may know certain counterfactuals in an empirical way and thereby gain epistemic access to some nearby, nomologically possible worlds. But I maintain that our beliefs about metaphysical necessities still cannot be justified empirically. Furthermore, I reject Casullo's deflationary thesis about the significance of such justification. Kitcher's most troublesome objection is that we can gain any modal justification whatsoever through testimony , i.e. in an experiential way. This can be countered by distinguishing between productive sources of justification, like perception, and merely reproductive sources, like testimony. Thus, some productive a priori source will always be needed somewhere. ¹     

Temporal Passage and Kant's Second Analogy

In this essay I address the question of the reality of temporal passage through a discussion of some of the implications of Kant's reasoning concerning the necessary conditions of objective judgement. Some theorists have claimed that the attribution of non-relational temporal properties to objects and events represents a conceptual confusion, or 'category mistake'. By means of an examination of Kant's Second Analogy, and a comparison between that argument and Cassam's recent exploration of an argument regarding the necessity of the conceptualisation of ourselves as spatially located, I draw out a consequence of Kant's argument: namely, that the representation of temporal becoming is a necessary condition of objective judgement and an a priori element in the representation of objects of experience. I finish by explaining why this would show that the attribution of temporal becoming to objects and events cannot be described as a category mistake.     

Kant on justification in transcendental philosophy

Kant's claim that the justification of transcendental philosophy is a priori is puzzling because it should be consistent with (1) his general restriction on the justification of knowledge, that intuitions must play a role in the justification of all nondegenerate knowledge, with (2) the implausibility of a priori intuitions being the only ones on which transcendental philosophy is founded, and with (3) his professed view that transcendental philosophy is not analytic. I argue that this puzzle can be solved, that according to Kant transcendental philosophy is justified a priori in the sense that the only empirical information required for its justification can be derived from any possible human experience. Transcendental justification does not rely on any more particular or special observations or experiments. Philip Kitcher's general account of apriority in Kant captures this aspect of a priori knowledge. Nevertheless, I argue that Kitcher's account goes wrong in the link it specifies between apriority and certainty.     

A Virtue-Based Defense of Mathematical Apriorism

Mathematical apriorists usually defend their view by contending that axioms are knowable a priori, and that the rules of inference in mathematics preserve this apriority for derived statements—so that by following the proof of a statement, we can trace the apriority being inherited. The empiricist Philip Kitcher attacked this claim by arguing there is no satisfactory theory that explains how mathematical axioms could be known a priori. I propose that in analyzing Ernest Sosa’s model of intuition as an intellectual virtue, we can construct an “intuition–virtue” that could supply the missing explanation for the apriority of axioms. I first argue that this intuition–virtue qualifies as an a priori warrant according to Kitcher’s account, and then show that it could produce beliefs about mathematical axioms independent of experience. If my argument stands, this paper could provide insight on how virtue epistemology could help defend mathematical apriorism on a larger scale.     

Phenomenal conservatism, classical foundationalism, and internalist justification

In “Compassionate Phenomenal Conservatism” (2007), “Phenomenal Conservatism and the Internalist Intuition” (2006), and Skepticism and the Veil of Perception (2001), Michael Huemer endorses the principle of phenomenal conservatism, according to which appearances or seemings constitute a fundamental source of (defeasible) justification for belief. He claims that those who deny phenomenal conservatism, including classical foundationalists, are in a self-defeating position, for their views cannot be both true and justified; that classical foundationalists have difficulty accommodating false introspective beliefs; and that phenomenal conservatism is most faithful to the central internalist intuition. I argue that Huemer’s self-defeat argument fails, that classical foundationalism is able to accommodate fallible introspective beliefs, and that classical foundationalism has no difficulty accommodating a relatively clear internalist intuition. I also show that the motivation for phenomenal conservatism is less than clear.     

Compassionate Phenomenal Conservatism

I defend the principle of Phenomenal Conservatism, on which appearances of all kinds generate at least some justification for belief. I argue that there is no reason for privileging introspection or intuition over perceptual experience as a source of justified belief; that those who deny Phenomenal Conservatism are in a self-defeating position, in that their view cannot be both true and justified; and that the demand for a metajustification for Phenomenal Conservatism either is an easily met demand, or is an unfair or question-begging one.     

Epistemically self-defeating arguments and skepticism about intuition

An argument is epistemically self-defeating when either the truth of an argument’s conclusion or belief in an argument’s conclusion defeats one’s justification to believe at least one of that argument’s premises. Some extant defenses of the evidentiary value of intuition have invoked considerations of epistemic self-defeat in their defense. I argue that there is one kind of argument against intuition, an unreliability argument, which, even if epistemically self-defeating, can still imply that we are not justified in thinking intuition has evidentiary value.     

Philosophical Intuition Is the Capacity to Recognize one’s Epistemic Position. An Old-Fashion Approach Based on Russell,Carnap, Wittgenstein,and Husserl

Philosophical intuition has become one of the most debated problems in recent years, largely due to the rise of the movement called experimental philosophy which challenged the conviction that philosophers have some special insight into abstract ideas such as being, knowledge, good and evil, intentional action, etc. In response to the challenge, some authors claim that there is a special cognitive faculty called philosophical intuition which delivers justification to philosophical theses, while some others deny it based on experimental results. A relatively smaller group of researchers aim at clarifying what the alleged intuition is. I follow the latter path. In this paper I argue that philosophical intuition is in the first place the capacity enabling one to what I refer to as the recognition of one’s epistemic position. The latter means becoming aware of the seemingly trivial “fact” that the way in which the world manifests itself depends on the cognitive apparatus one has, thereby propelling one to draw a distinction between appearances and reality. The recognition at stake is a very specific capacity to approach the world solely as it is experienced. This capacity, I argue, is the core and the defining feature of philosophical intuition. As part of my argumentation I also distinguish between the intuition in question and its different manifestations; and then introduce a novel notion of erotetic intuition. My argument is called “old-fashion” to emphasize the fact that I draw mostly on four figures who were pivotal in the twentieth- century philosophy and whose influence on the current debate concerning philosophical intuition should be, I believe, stronger than it is; I mean Russell, Carnap, Wittgenstein, and Husserl.

     

Constitutivism and Transcendental Practical Philosophy: How to Pull the Rabbit Out of the Hat

Constitutivism aims to justify substantial normative standards as constitutive of practical reason. In this way, it can defend the constructivist commitment to avoiding realism and anti-realism in normative disciplines. This metaphysical debate is the perspective from which the nature of the constitutivist justification is usually discussed. In this paper, I focus on a related, but distinct, debate. My concern will not be whether the substantial normative claims asserted by the constructivist have some elements, which are not constructed, but real, given independently from us; instead, my concern will be more narrowly epistemic – whether those claims can be derived from premises, which are normatively less substantial than the normative conclusions themselves. I focus on Korsgaard’s transcendental articulation of the constitutivist argument. I conclude that more work would need to be done, in order for this argument to function as intended.     

Hilary Putnam And Immanuel Kant: Two `Internal Realists'?

Since 1976 Hilary Putnam has drawn parallels between his `internal',`pragmatic', `natural' or `common-sense' realism and Kant's transcendentalidealism. Putnam reads Kant as rejecting the then current metaphysicalpicture with its in-built assumptions of a unique, mind-independent world,and truth understood as correspondence between the mind and that ready-madeworld. Putnam reads Kant as overcoming the false dichotomies inherent inthat picture and even finds some glimmerings of conceptual relativity inKant's proposed solution. Furthermore, Putnam reads Kant as overcoming thepernicious scientific realist distinction between primary and secondaryqualities, between things that really exist and their projections, adistinction that haunts modern philosophy. Putnam's revitalisation of Kantis not just of historical interest, but challenges contemporary versions ofscientific realism. Furthermore, Putnam has highlighted themes which havenot received the attention they deserve in Kantian exegesis, namely, theproblematic role of primary and secondary qualities in Kant's empiricalrealism, and the extent of Kant's commitment to conceptual pluralism.However, I argue that Putnam's qualified allegiance to Kant exposes him tosome of the same metaphysical problems that affected Kant, namely, thefamiliar problem of postulating an absolute reality (Ding an sich), while atthe same time disavowing the meaningfulness of so doing. In conclusion Isuggest that Putnam might consider Hegel's attempts to solve this problem inKant as a way of furthering his own natural realism.     

Intuition and The Junctures of Judgment in Decision Procedures for Clinical Ethics

Moral decision procedures such as principlism or casuistry require intuition at certain junctures, as when a principle seems indeterminate, or principles conflict, or we wonder which paradigm case is most relevantly similar to the instant case. However, intuitions are widely thought to lack epistemic justification, and many ethicists urge that such decision procedures dispense with intuition in favor of forms of reasoning that provide discursive justification. I argue that discursive justification does not eliminate or minimize the need for intuition, or constrain our intuitions. However, this is not a problem, for intuitions can be justified in easy or obvious cases, and decision procedures should be understood as heuristic devices for reaching judgments about harder cases that approximate the justified intuitions we would have about cases under ideal conditions, where hard cases become easy. Similarly, the forms of reasoning which provide discursive justification help decision procedures perform this heuristic function not by avoiding intuition, but by making such heuristics more accurate. Nonetheless, it is possible to demand too much justification; many clinical ethicists lack the time and philosophical training to reach the more elaborate levels of discursive justification. We should keep moral decision procedures simple and user-friendly so that they will provide what justification can be achieved under clinical conditions, rather than trying to maximize our epistemic justification out of an overstated concern about intuition.     

Cosmopolitan Pacifism

In this paper I argue that cosmopolitanism prohibits war and requires a global approach to criminal justice. My argument proceeds by drawing out some implications of the core cosmopolitan intuition that every human being has a moral status which constrains how they may be treated. In the first part of this paper, I describe cosmopolitanism. In the second part, Cosmopolitanism and War, I analyse violence, consider the standards cosmopolitanism sets for its justification, and argue that war fails to meet them. In the third part, Cosmopolitanism and Criminal Justice, I argue that cosmopolitanism implies a moral obligation to deal justly with human wrongdoing wherever it occurs. Cosmopolitan pacifism follows: war is prohibited, and a consistent global criminal justice system is required. In the fourth part, Why No Cosmopolitan Pacifists?, I consider why cosmopolitans tend not to identify as pacifists, and in the final part, Objections, I discuss some objections.     

Self-understanding in Kant's Transcendental Deduction

I argue that §§15–20 of the B-Deduction contain two independent arguments for the applicability of a priori concepts, the first an argument from above, the second an argument from below. The core of the first argument is §16's explanation of our consciousness of subject-identity across self-attributions, while the focus of the second is §18's account of universality and necessity in our experience. I conclude that the B-Deduction comprises powerful strategies for establishing its intended conclusion, and that some assistance from empirical psychology might well have produced a completely successful argument.     

Modal rationalism and the demonstrative reply to the scrutability argument against physicalism

According to the scrutability argument against physicalism, an a priori gap between the physical and conscious experience entails a lack of necessitation and the falsity of physicalism. This paper investigates the crucial premise of the scrutability argument: the inference from an a priori gap to a lack of necessitation. This premise gets its support from modal rationalism, according to which there are important, potentially constitutive, connections between a priori justification and metaphysical modality. I argue against the strong form of modal rationalism that underwrites the scrutability argument and suggest a more moderate rationalist view. I offer a novel demonstrative reply to the scrutability argument, according to which demonstratives play a vital role in the generation of meaning for our representations of conscious experience. This connection between conscious experience and demonstratives, rather than a metaphysical gap generated by the truth of dualism, is the source of the epistemic gap between consciousness and the physical.

     

Radical Scepticism,How-Possible Questions and Modest Transcendental Arguments

According to radical scepticism, knowledge of the external world is impossible. Transcendental arguments are supposed to be anti-sceptical, but can they provide a satisfying response to radical scepticism? Especially, when radical scepticism is cast as posing a how-possible question, there is a concern that transcendental arguments are neither sufficient nor necessary for answering such question. In light of this worry, I argue that we can take a modest transcendental argument as a stepping stone for a diagnostic anti-sceptical proposal, and I use a Wittgensteinian modest transcendental argument to illustrate my point.     

ROCK BOTTOM: COHERENTISM'S SOFT SPOT

Often coherentism is taken to be the view that justification is solely a function of the coherence among a person's beliefs. I offer a counterexample to the idea that when so understood coherence is sufficient for justification. I then argue that the counterexample will still work if coherence is understood as coherence among a person's beliefs and experiences. I defend a form of nondoxastic foundationalism that takes sensations and philosophical intuitions as basic and sees nearly all other justification as depending on inference to the best explanation. I take up Wilfrid Sellars's Dilemma, which starts with the idea that the foundations must be either propositional in nature or not. The argument continues: if they are, they stand in need of justification; if they are not, they cannot confer justification. It concludes that there cannot be foundations that confer justification on other beliefs. I deny both horns of this dilemma, arguing that philosophical intuitions are propositional but do not stand in need of justification and that sensations are not propositional but can confer justification on perceptual beliefs.     

Why Should I Respect You? A Critique and a Suggestion for the Justification of Mutual Respect in Contractualism

Contractualism is a normative theory which characterizes principles of right in terms of the idea of mutual respect. In this theory, mutual respect is regarded as having deliberative priority over other values. This essay aims to examine how contractualists can provide a satisfactory justification for prioritizing mutual respect. I will argue that the “value of mutual respect argument,” which is a justification commonly adopted by contractualists, is inadequate because an unconditional priority of mutual respect cannot be grounded on the desirability of a relationship of mutual respect. Then, I will suggest that a “consistency argument” can provide a better justification of why the idea of mutual respect should have priority. Mutual respect is of special importance, not because it is highly desirable, but rather because it is required by an a priori guiding principle of consistency. Individuals become inconsistent if they ask others to respect them as reason-assessing individuals, while at the same time refusing to respect others in the same way.     

Scepticism,defeasible evidence and entitlement

The paper starts by describing and clarifying what Williamson calls the consequence fallacy. I show two ways in which one might commit the fallacy. The first, which is rather trivial, involves overlooking background information; the second way, which is the more philosophically interesting, involves overlooking prior probabilities. In the following section, I describe a powerful form of sceptical argument, which is the main topic of the paper, elaborating on previous work by Huemer. The argument attempts to show the impossibility of defeasible justification, justification based on evidence which does not entail the (allegedly) justified proposition or belief. I then discuss the relation between the consequence fallacy, or some similar enough reasoning, and that form of argument. I argue that one can resist that form of sceptical argument if one gives up the idea that a belief cannot be justified unless it is supported by the totality of the evidence available to the subject—a principle entailed by many prominent epistemological views, most clearly by epistemological evidentialism. The justification, in the relevant cases, should instead derive solely from the prior probability of the proposition. A justification of this sort, that does not rely on evidence, would amount to a form of entitlement, in (something like) Crispin Wright’s sense. I conclude with some discussion of how to understand prior probabilities, and how to develop the notion of entitlement in an externalist epistemological framework.     

Kant on geometry and spatial intuition

I use recent work on Kant and diagrammatic reasoning to develop a reconsideration of central aspects of Kant??s philosophy of geometry and its relation to spatial intuition. In particular, I reconsider in this light the relations between geometrical concepts and their schemata, and the relationship between pure and empirical intuition. I argue that diagrammatic interpretations of Kant??s theory of geometrical intuition can, at best, capture only part of what Kant??s conception involves and that, for example, they cannot explain why Kant takes geometrical constructions in the style of Euclid to provide us with an a priori framework for physical space. I attempt, along the way, to shed new light on the relationship between Kant??s theory of space and the debate between Newton and Leibniz to which he was reacting, and also on the role of geometry and spatial intuition in the transcendental deduction of the categories.
