Deleuze's Use of Kant's Argument from Incongruent Counterparts

The aim of this paper is to explore Deleuze's use of Kant's argument from incongruent counterparts, which Kant uses to show the existence of what he calls an “internal difference” within things. I want to explore how Deleuze draws out an important distinction between the concept and the Idea, and provides an incisive account of his relationship to both the Kantian and Leibnizian projects. First, I look at Kant's use of the argument to provide a refutation of the Leibnizian account of space, before showing how this criticism in fact rests on the question of the conceptual determination of object. Second, I show how Deleuze develops a taxonomy of difference on the basis of his reading of Kant's argument. Finally, I look at what Deleuze sees as the limitations in Kant's understanding of this concept and Deleuze's attempt to overcome these limitations through the introduction of the notion of the Idea, which will provide a genetic and nonconceptual account of the object. In doing so, I show why Deleuze takes the formulation of an adequate account of difference to be one of the central aims of his own metaphysics.     

What Incongruent Counterparts Show

Abstract: In a recent paper, Robert Hanna argues that Kant's incongruent counterparts example can be mobilized to show that some mental representations, which represent complex states of affairs as complex, do so entirely non‐conceptually. I will argue that Hanna is right to see that Kant uses incongruent counterparts to show that there must be a non‐conceptual component to cognition, but goes too far in concluding that there must be entirely non‐conceptual representations that represent objects as existing in space and time. Kant is deeply committed to the thesis that no representation of a complex state of affairs as complex can be entirely non‐conceptual. For Kant, all representations of complex states of affairs as complex (including those of incongruent counterparts) are conceptually structured. I present an interpretation of the Transcendental Aesthetic according to which Kant not only aims at Leibnizian and Newtonian accounts of space and time, but also Hume's. Hume's account fails to make representations of complex states of affairs sufficiently determinate. Kant offers an account later in the Critique that is meant to correct this failing by requiring that all representations of complex states of affairs as complex be conceptually (inferentially) structured.     

Temporal Vacua

I show to be unsuccessful several attempts to demonstrate the possibility of time without change. Consideration of the most prominent of these arguments (by Sydney Shoemaker) then leads to the formulation of a general argument: evidence which justifies a claim that a certain amount of time has elapsed also justifies a claim that continuous change has occurred during the period. Hence there is a sound basis for the relationist claim that there is no time without events.     

Tracing and heavenly freedom

A new version of the ontological argument for the existence of God is outlined and examined. After giving a brief account of some traditional ontological arguments for the existence of God, where their defects are identified, it is explained how this new argument is built upon their foundations and surmounts their defects. In particular, this version uses the resources of impossible worlds to plug the common escape route from standard modal versions of the ontological argument. After outlining the nature of impossible worlds, and motivating the need for positing them, the new argument is delineated and its premises justified. It is taken for granted that the argument cannot be sound, since it would prove too much. However, its premises are all plausible, and their denial promises to have significant ramifications. Several intuitive lines of objections are then explored in order to illuminate their shortcomings. The puzzle that the argument poses is therefore not whether the argument is sound, for it clearly cannot be. Rather, it is to place pressure on its plausible premises, so some plausible account of how the argument fails can be identified, and that the devising of such an account promises to be insightful. In the process, we should gain an improved understanding of how such ontological arguments work.     

Reddish Green: A Challenge for Modal Claims About Phenomenal Structure1

We discuss two modal claims about the phenomenal structure of color experiences: (i) violet experiences are necessarily experiences of a color that is for the subject on that occasion phenomenally composed of red and blue (the modal claim about violet) and (ii) no subject can possibly have an experience of a color that is for it then phenomenally composed of red and green (the modal claim about reddish green). The modal claim about reddish green is undermined by empirical results. We discuss whether these empirical results cast doubt on the other modal claims as well. We argue that this not the case. Our argument is based on the thesis that the best argument for the modal claim about violet is quite different from the best argument for the modal claim about reddish green. To argue for this disanalogy we propose a reconstruction of the best available justification for both claims.     

A PUZZLE ABOUT INCONGRUENT COUNTERPARTS AND THE CRITIQUE OF PURE REASON

Abstract:   Kant uses incongruent counterparts in his work before and after 1781, but not in the first Critique . Given the relevance that incongruent counterparts had for his thought on space, and their persistence in his work during the 1780s, it is plausible to think that he had a reason for leaving them out of both editions of the Critique . Two implausible conjectures for their absence are here considered and rejected. A more plausible alternative is put forth, which explains that textual absence as a result of the synthetic method of presentation intended for the Critique .     

Van Inwagen’s modal skepticism

In this paper, the author defends Peter van Inwagen’s modal skepticism. Van Inwagen accepts that we have much basic, everyday modal knowledge, but denies that we have the capacity to justify philosophically interesting modal claims that are far removed from this basic knowledge. The author also defends the argument by means of which van Inwagen supports his modal skepticism, offering a rebuttal to an objection along the lines of that proposed by Geirrson. Van Inwagen argues that Stephen Yablo’s recent and influential account of the relationship between conceivability and possibility supports his skeptical claims. The author’s defence involves a creative interpretation and development of Yablo’s account, which results in a recursive account of modal epistemology, what the author calls the “safe explanation” theory of modal epistemology.     

Finean essence,local necessity,and pure logical properties

Since Kit Fine published his famous counter-examples to the modal account of essence, numerous modalists have proposed to avoid the counter-examples by revising the modal account. A sophisticated revision has been put forward by Fabrice Correia. Drawing on themes from Prior’s modality, Correia has introduced a nonstandard conception of metaphysical modality and has proposed to analyze essence in its terms. He has claimed that the analysis is immune to Fine’s counter-examples. In this paper, I argue that there are counter-examples supported by the very intuition underlying Fine’s counter-examples, which are not accommodated by Correia’s account. If my argument is sound, then Correia has not been successful in his defense of modalism. An important corollary of my argument will be that Fine’s consequential conception of essence needs to be modified if it is to capture his own intuitive notion of essence.     

Vagueness as a Modality

I present a modal conception of vagueness and vague objects, according to which a vague object is a transworld object which coincides with one precise object in one world and with another precise object in another world. Such worlds are called precisifications; they are modal, worldly counterparts of the precisifications postulated in supervaluationism. I criticize Evans' argument against vague objects, admitting the validity of the argument, but rejecting its basic assumption that if there are vague objects, certain identity statements must be indefinite in truth value. I distinguish identity from coincidence, and claim that if there are vague objects, some statements of coincidence will be indefinite in truth-value, not statements of identity. To establish this point, I compare vagueness with temporal modality.     

Illusions of Optimal Motion,Relationism, and Perceptual Content

Austere relationism rejects the orthodox analysis of hallucinations and illusions as incorrect perceptual representations. In this article, I argue that illusions of optimal motion (IOMs) present a serious challenge for this view. First, I submit that austere‐relationist accounts of misleading experiences cannot be adapted to account for IOMs. Second, I show that any attempt at elucidating IOMs within an austere‐relationist framework undermines the claim that perceptual experiences fundamentally involve relations to mind‐independent objects. Third, I develop a representationalist model of IOMs. The proposed analysis combines two ideas: Evans' dynamic modes of presentation and Fine's relational semantics for identity.     

Do incompatible arguments cause extensive processing in the evaluation of arguments? The role of congruence between argument compatibility and argument quality

Previous studies have demonstrated that arguments incompatible with prior beliefs are subjected to more extensive refutational processing, scrutinized longer, and judged to be weaker than arguments compatible with prior beliefs. However, this study suggests whether extensive processing is implemented when evaluating arguments is not decided by argument compatibility, but by congruence between two evaluating tendencies elicited by both argument compatibility and argument quality. Consistent with this perspective, the results of two experiments show that relative to congruent arguments, participants judged arguments eliciting incongruent evaluating tendencies as less extreme in strength, spent more time, and felt more hesitant generating strength judgments for them. The results also show that it is mainly incongruent arguments, not congruent arguments, whose strength ratings were more closely associated with the perceived personal importance of the issue, which intensified the tendency to evaluate arguments depending on argument compatibility. These results suggest that it is the incongruity between argument compatibility and argument quality, and not simply the argument compatibility, that plays a more important role in activating an extensive processing in the evaluation of arguments.     

Hegel's Essentialism. Natural Kinds and the Metaphysics of Explanation in Hegel's Theory of ‘the Concept’

Several recent interpretations see Hegel's theory of the Concept as a form of conceptual realism, according to which finite reality is articulated by objectively existing concepts. More precisely, this theory has been interpreted as a version of natural kind essentialism, and it has been proposed that its function is to account for the possibility of genuine explanations. This suggests a promising way to reconstruct the argument that Hegel's theory of objective concepts is based on—an argument that shows that the possibility of explanation rests on metaphysical preconditions and that natural kind essentialism gives the only adequate account of those preconditions. But in order for such a reconstruction to be successful, one needs to spell out the metaphysical features in virtue of which Hegelian natural kinds can account for the possibility of explanation. The article takes up this challenge. It offers the first detailed analysis of the modal fine‐structure of Hegel's natural kind essentialism and shows how Hegel's position, thus understood, provides the details needed to complete the explanation‐based argument.     

Conceivability,Imagination and Modal Knowledge*

The notion of conceivability has traditionally been regarded as crucial to an account of modal knowledge. Despite its importance to modal epistemology, there is no received explication of conceivability. One purpose of this paper is to argue that the notion is not fruitfully explicated in terms of the imagination. The most natural way of presenting a notion of conceivability qua imaginability is open to cogent criticism. In order to avoid such criticism, an advocate of the modal insightfulness of the imagination must broaden the idea of what it is to be imaginable. I argue that this required broadening renders the imagination idle (in this context). Consequently, I distinguish two different accounts of the evidential basis of modal knowledge and present a more general argument that concludes that the very notion of conceivability should be eschewed in modal epistemology.     

Kagan on Speciesism and Modal Personism

Shelly Kagan argues in his ‘What's Wrong with Speciesism?’ for four provocative claims: 1. speciesism is not necessarily a mere prejudice; 2. most people are not speciesists; 3. ‘modal personism’ more closely reflects what most people believe, and 4. modal personism might be true. In this article, I object to Kagan's account of what constitutes a ‘mere prejudice’, and I object to the sort of argument he uses to show that most people are not speciesist. I then attempt to motivate, and defend what I take to be the best version of modal personism; answer several problems for the view; and raise other problems that I think are harder to answer.     

On behalf of the consequence argument: time, modality, and the nature of free action

The consequence argument for the incompatibility of free action and determinism has long been under attack, but two important objections have only recently emerged: Warfield’s modal fallacy objection and Campbell’s no past objection. In this paper, I explain the significance of these objections and defend the consequence argument against them. First, I present a novel formulation of the argument that withstands their force. Next, I argue for the one controversial claim on which this formulation relies: the trans-temporality thesis. This thesis implies that an agent acts freely only if there is one time at which she is able to perform an action and a distinct time at which she actually performs it. I then point out that determinism, too, is a thesis about trans-temporal relations. I conclude that it is precisely because my formulation of the consequence argument emphasizes trans-temporality that it prevails against the modal fallacy and no past objections.     

THE TROUBLE WITH MARY

Abstract: Two arguments are famously held to support the conclusion that consciousness cannot be explained in purely physical or functional terms – hence, that physicalism is false: the modal argument and the knowledge argument. While anti‐physicalists appeal to both arguments, this paper argues there is a methodological incoherence in jointly maintaining them: the modal argument supports the possibility of zombies; but the possibility of zombies undercuts the knowledge argument. At best, this leaves anti‐physicalists in a considerably weakened rhetorical position. At worst, it shows that commonsense intuitions on which anti‐physicalists rely mislead us about the true nature of conscious experience.     

Skepticism and Epistemic Logic

This essay attempts to implement epistemic logic through a non-classical inference relation. Given that relation, an account of '(the individual) a knows that A' is constructed as an unfamiliar non-normal modal logic. One advantage to this approach is a new analysis of the skeptical argument.     

Temporally Incongruent Counterparts

Despite its first page this paper is not yet another piece on Kant! Rather, the paper is a contribution to the literature on incongruent counterparts. Specifically, it concerns the question of whether we can construct a temporal version of the puzzle of incongruent counterparts—a question which (as far as 1 can tell) has been thoroughly neglected. I maintain that we can construct such a version of the puzzle, and that this temporal variant on the phenomenon has something to teach us about popular arguments for the possibility (or even actuality) of four-dimensional space.
