A limited defense of moral perception

One popular reason for rejecting moral realism is the lack of a plausible epistemology that explains how we come to know moral facts. Recently, a number of philosophers have insisted that it is possible to have moral knowledge in a very straightforward way—by perception. However, there is a significant objection to the possibility of moral perception: it does not seem that we could have a perceptual experience that represents a moral property, but a necessary condition for coming to know that X is F by perception is the ability to have a perceptual experience that represents something as being F. Call this the ‘Representation Objection’ to moral perception. In this paper I argue that the Representation Objection to moral perception fails. Thus I offer a limited defense of moral perception.     

The Contents of Perception and the Contents of Emotion

Several philosophers think there are important analogies between emotions and perceptual states. Furthermore, considerations about the rational assessibility of emotions have led philosophers—in some cases, the very same philosophers—to think that the content of emotions must be propositional content. If one finds it plausible that perceptual states have propositional contents, then there is no obvious tension between these views. However, this view of perception has recently been attacked by philosophers who hold that the content of perception is object‐like. I shall argue for a view about the content of emotions and perceptual states which will enable us to hold both that emotional content is analogous to perceptual content and that both emotions and perceptual states can have propositional contents. This will involve arguing for a pluralist view of perceptual content, on which perceptual states can have both contents which are proposition‐like and contents which are object‐like. I shall also address two significant objections to the claim that emotions can have proposition‐like contents. Meeting one of these objections will involve taking on a further commitment: the pluralist account of perceptual content will have to be one on which the contents of perception can be non‐conceptual.     

A Posteriori Ethical Intuitionism and the Problem of Cognitive Penetrability

According to a posteriori ethical intuitionism (AEI), perceptual experiences can provide non‐inferential justification for at least some moral beliefs. Moral epistemology, for the defender of AEI, is less like the epistemology of math and more like the epistemology of tables and chairs. One serious threat to AEI comes from the phenomenon of cognitive penetration. The worry is that even if evaluative properties could figure in the contents of experience, they would only be able to do so if prior cognitive states influence perceptual experience. Such influences would undermine the non‐inferential, foundationalist credentials of AEI. In this paper, I defend AEI against this objection. Rather than deny that cognitive penetration exists, I argue that some types of cognitive penetrability are actually compatible with AEI's foundationalist structure. This involves teasing apart the question of whether some particular perceptual process has justification‐conferring features from the question of how it came to have those features in the first place. Once this distinction is made, it becomes clear that some kinds of cognitive penetration are compatible with the non‐inferential status of moral perceptual experiences as the proponent of AEI claims.     

Normatively Enriched Moral Meta‐Semantics

In order to defend the Cornell variety of naturalistic moral realism from Horgan and Timmons’ Moral Twin Earth objection, several philosophers have proposed what I call Normatively Enriched Moral Meta‐Semantics (NEMMS). According to NEMMS, the natural properties that serve as the contents of moral predicates are fixed (at least in part) by non‐moral normative facts. In this paper, I elucidate two versions of NEMMS: one proposed by David Brink, and the other proposed by Mark van Roojen. I show what these meta‐semantics have in common, and how each one promises the Cornell realist a response to the Moral Twin Earth objection. I then argue that Cornell realists ought to be wary of adopting NEMMS. A naturalist realist who adopts this meta‐semantics confronts a trilemma. The proponent of NEMMS owes a meta‐ethical account of the relevant content‐fixing normative facts. Such facts are either reducible to recognizably natural facts or they are not. If they are not reducible, then NEMMS entails the denial of ethical naturalism (and so, the denial of Cornell realism). If such facts are taken to be reducible to facts about agents’ actual or hypothetical attitudes, then (among other problems) the account renders moral facts stance‐dependent. Consequently, moral realism is false. Alternatively, one might propose that the content‐fixing normative facts are reducible to attitude‐independent natural facts. However, such a proposal is refuted by its own Twin Earth objection.     

Action and Variation in Perception

In her paper, ‘Action and Self‐location in Perception’, Susanna Schellenberg argues that perceptual experience of an object's intrinsic spatial properties, such as its size and shape, requires a capacity to act. More specifically, Schellenberg argues that, to have a perceptual experience of an object's intrinsic spatial properties, a subject needs to have a certain practical conception of space, or a spatial know‐how. That, in turn, requires self‐locating representations, which locate the subject, relative to the perceptual object, as a perceiver and an agent, viz., someone who has a capacity for actions. She also makes two objections, viz., the unification objection and the sentient statue objection, to Alva Noë's sensorimotor view, a different account of how perceptual experience depends on actions. I will argue that her objections jointly render problematic not only Noë's but also her own view.     

Organic Unities

I defend the view that there are organic unities mainly by presenting examples of organic unities. I also defend the view against two objections. The first objection appeals to the notion of an evaluatively incomplete state of affairs. The second objection holds that the intrinsic value of a state of affairs can be different in different contexts. I argue that neither objection provides a compelling reason for rejecting these examples.     

MORAL PERCEPTION AND THE CAUSAL OBJECTION

One of the primary motivations behind moral anti‐realism is a deep‐rooted scepticism about moral knowledge. Moral realists attempt counter this worry by sketching a plausible moral epistemology. One of the most radical proposals in the recent literature is that we know moral facts by perception – we can literally see that an action is wrong, etc. A serious objection to moral perception is the causal objection. It is widely conceded that perception requires a causal connection between the perceived and the perceiver. But, the objection continues, we are not in appropriate causal contact with moral properties. Therefore, we cannot perceive moral properties. This papers demonstrates that the causal objection is unsound whether moral properties turn out to be secondary, natural properties; non‐secondary, natural properties; or non‐natural properties. 1     

Sentimental perceptualism and the challenge from cognitive bases

According to a historically popular view, emotions are normative experiences that ground moral knowledge much as perceptual experiences ground empirical knowledge. Given the analogy it draws between emotion and perception, sentimental perceptualism constitutes a promising, naturalist-friendly alternative to classical rationalist accounts of moral knowledge. In this paper, we consider an important but underappreciated objection to the view, namely that in contrast with perception, emotions depend for their occurrence on prior representational states, with the result that emotions cannot give perceptual-like access to normative properties. We argue that underlying this objection are several specific problems, rooted in the different types of mental states to which emotions may respond, that the sentimental perceptualist must tackle for her view to be successful. We argue, moreover, that the problems can be answered by filling out the theory with several independently motivated yet highly controversial commitments, which we carefully catalogue. The plausibility of sentimental perceptualism, as a result, hinges on further claims sentimental perceptualists should not ignore.

     

Taking the Perceptual Analogy Seriously

This paper offers a qualified defense of a historically popular view that I call sentimental perceptualism. At a first pass, sentimental perceptualism says that emotions play a role in grounding evaluative knowledge analogous to the role perceptions play in grounding empirical knowledge. Recently, András Szigeti and Michael Brady have independently developed an important set of objections to this theory. The objections have a common structure: they begin by conceding that emotions have some important epistemic role to play, but then go on to argue that understanding how emotions play that role means that there must be some alternative, emotion-independent route to obtaining knowledge of value. If there has to be such an emotion-independent route, then the perceptual analogy breaks down in a significant way. In this paper, I argue that the right ways for sentimental perceptualists to respond to each of these objections are revealed by thinking through how analogous objections applied to perception and the empirical domain would be answered. Although Szigeti's and Brady's objections should not persuade sentimental perceptualists to give up their view, the objections do put important constraints on what a form of the view has to be like in order to do exciting metaethical work.     

Common sense and Berkeley's perception by suggestion

Abstract

Significant attention has been paid to Berkeley's account of perception; however, the interpretations of Berkeley's account of perception by suggestion are either incomplete or mistaken. In this paper I begin by examining a common interpretation of suggestion, the ‘Propositional Account’. I argue that the Propositional Account is inadequate and defend an alternative, non‐propositional, account. I then address George Pitcher's objection that Berkeley's view of sense perception forces him to adopt a ‘non‐conciliatory’ attitude towards common sense. I argue that Pitcher's charge is no longer plausible once we recognize that Berkeley endorses the non‐propositional sense of mediate perception. I close by urging that the non‐propositional interpretation of Berkeley's account of mediate perception affords a greater appreciation of Berkeley's attempt to bring a philosophical account of sense perception in line with some key principles of common sense. While Berkeley's account of perception and physical objects permits physical objects to be immediately perceived by some of the senses, they are, most often, mediately perceived. But for Berkeley this is not a challenge to common sense since common sense requires only that we perceive objects by our senses and that they are, more or less, as we perceive them. Mediate perception by suggestion is, for Berkeley, as genuine a form of perception as immediate perception, and both are compatible with Berkeley's understanding of the demands of common sense.     

Knowledge as a Non‐Normative Relation

According to a view I’ll call Epistemic Normativism (EN), knowledge is normative in the same sense in which paradigmatically normative properties like justification are normative. This paper argues against EN in two stages and defends a positive non‐normativist alternative. After clarifying the target in §1, I consider in §2 some arguments for EN from the premise that knowledge entails justification (the “Entailment Thesis”). I first raise some worries about inferring constitution from entailment. I then rehearse the reasons why some epistemologists reject the Entailment Thesis and argue that a non‐normativist picture provides the best explanation of all the intuitions surrounding this thesis, favorable and unfavorable. On this picture, human knowledge is a structured non‐normative complex that has as one of its parts a justification‐making property, analogous in role to good‐making properties like pleasurableness. After giving three arguments against EN in §3 and answering an objection in §4, I turn in §5 to further develop the positive view sketched in §2. In §6, I take stock and conclude.     

NON‐CONCEPTUAL KNOWLEDGE

The paper is an investigation into the prospects of an epistemology of non‐conceptual knowledge. According to the orthodox view, knowledge requires concepts and belief. I present several arguments to the effect that there is non‐conceptual, non‐doxastic knowledge, the obvious candidate for such knowledge being non‐conceptual perception. Non‐conceptual perception seems to be allowed for by cognitive scientists and it exhibits the central role features of knowledge—it plays the knowledge role: it respects an anti‐luck condition, it is an achievement, it enables one to act for a reason, and it provides justification. Furthermore, it makes a straightforward and elegant explanation of (doxastic) perceptual knowledge possible: doxastic perceptual knowledge builds on non‐conceptual perception as non‐conceptual knowledge. Three objections that might naturally arise will be discussed and answered. Thus, the prospects of an epistemology without belief seem to be much better than the orthodoxy wants to have it. We can extend knowledge into the non‐conceptual realm.     

Moral Enhancement

abstract   Opponents of biomedical enhancement often claim that, even if such enhancement would benefit the enhanced, it would harm others. But this objection looks unpersuasive when the enhancement in question is a moral enhancement — an enhancement that will expectably leave the enhanced person with morally better motives than she had previously. In this article I (1) describe one type of psychological alteration that would plausibly qualify as a moral enhancement, (2) argue that we will, in the medium-term future, probably be able to induce such alterations via biomedical intervention, and (3) defend future engagement in such moral enhancements against possible objections. My aim is to present this kind of moral enhancement as a counter-example to the view that biomedical enhancement is always morally impermissible.     

V—Naive Realism and Experiential Evidence

I describe a naive realist conception of perceptual knowledge, which faces a challenge from the idea that normal perceivers and brains-in-vats have equally justified perceptual beliefs. I defend the naive realist position from Nicholas Silins's recent version of this challenge. I argue that Silins's main objection fails, and that the naive realist understanding of perceptual knowledge can be reconciled with the idea that brains-in-vats have justified perceptual beliefs.     

A Defence of the Indispensability of Metaphor

I argue for the possibility of the thesis that metaphors are indispensable for grasping and expressing certain propositions. I defend this possibility against the objection that, if metaphors express propositions, once these propositions are identified they should be specifiable by non‐metaphorical means. I argue that this objection loses its strength if one adopts a Wittgensteinian, particularist view of thought, according to which grasping a propositional thought requires the ongoing exercise of a suitable skill often not characterizable by algorithmic rules. Within this particularist framework, thus, it becomes possible that metaphorical skills have an indispensable role in cognition and communication.     

Sellars and Nonconceptual Content

In this paper I take up the question of whether Wilfrid Sellars has a notion of non‐conceptual perceptual content. The question is controversial, being one of the fault lines along which so‐called left and right Sellarsians diverge. In the paper I try to make clear what it is in Sellars' thought that leads interpreters to such disparate conclusions. My account depends on highlighting the importance of Sellars' little discussed thesis that perception involves a systematic form of mis‐categorization, one where perceivers mistake their sensory states to be properties of physical objects. I argue that the counterpart color and shape attributes of these states, which become ‘point of viewish’ when organized by the productive imagination, provides perceptual experience with its non‐conceptual representational content. I then argue that this content is not a form of the mythical Given because one can only have a non‐conceptual point of view on an object when an object is introduced into one's perceptual experience through the conceptual mis‐taking of one's sensory states. So, while Sellars has a notion of non‐conceptual representational content, it can only be salient in the context of a perceptual act that is conceptual overall.     

Moral Hedging and Responding to Reasons

In this paper, I argue that the fetishism objection to moral hedging fails. The objection rests on a reasons‐responsiveness account of moral worth, according to which an action has moral worth only if the agent is responsive to moral reasons. However, by adopting a plausible theory of non‐ideal moral reasons, one can endorse a reasons‐responsiveness account of moral worth while maintaining that moral hedging is sometimes an appropriate response to moral uncertainty. Thus, the theory of moral worth upon which the fetishism objection relies does not, in fact, support that objection.     

THE VISUAL EXPERIENCE OF CAUSATION

The thesis that we can visually perceive causal relations is distinct from the thesis that visual experiences can represent causal relations. I defend the latter thesis about visual experience, and argue that although they are suggestive, the data provided by Albert Michotte's experiments on perceptual causality do not establish this thesis. Turning to the perception of causality, I defend the claim that we can perceive causation against the objection that its arcane features are unlikely to be represented in experience.     

Demarcating depression

How to draw the line between depression‐as‐disorder and non‐pathological depressive symptoms continues to be a contested issue in psychiatry. Relatively few philosophers have waded into this debate, but the tools of philosophical analysis are quite relevant to it. In this paper, I defend a particular answer to this question, the Contextual approach. On this view, depression is a disorder if and only if it is a disproportionate response to a justifying cause or else is unconnected to any justifying cause. I present four objections to this approach and then defend it from them. Along the way, I explain why it matters whether we get this question right.     

Perceptual Content Defended

Recently, the thesis that experience is fundamentally a matter of representing the world as being a certain way has been questioned by austere relationalists. I defend this thesis by developing a view of perceptual content that avoids their objections. I will argue that on a relational understanding of perceptual content, the fundamental insights of austere relationalism do not compete with perceptual experience being representational. As it will show that most objections to the thesis that experience has content apply only to accounts of perceptual content on which perceptual relations to the world play no explanatory role. With austere relationalists, I will argue that perceptual experience is fundamentally relational. But against austere relationalists, I will argue that it is fundamentally both relational and representational.
