Emotion

Emotions are at once felt, bodily, intentional, motivational, evaluative, and socially shaped. Fear may involve arousal, represent a situation as dangerous, focus attention, prepare escape, and feel a distinctive way. No one feature appears in every emotion or suffices by itself. The philosophy of emotion asks which features constitute an emotion, how emotions can be rationally assessed, and how biological regularities interact with cultural concepts and practices.

The main theories treat emotions as feelings, perceptions of bodily change, judgments or appraisals, action tendencies, perceptions of value, or constructed categories. They often describe different components rather than exclusive essences. The challenge is to explain their coordination and their possible dissociation.

What must a theory explain?

Emotions characteristically involve several dimensions:

• phenomenology: what fear, grief, anger, or joy feels like;
• intentionality: what the emotion is about;
• appraisal: how the object is evaluated as dangerous, offensive, lost, or welcome;
• bodily change: arousal, posture, expression, and visceral regulation;
• motivation: tendencies to flee, confront, withdraw, repair, or approach;
• attention: selective salience and memory;
• social norm: when an emotion is fitting, excessive, shameful, or expected.

The dimensions can separate. One can judge danger without fear, feel anxious without a clear object, or remain afraid while believing the threat harmless. Such recalcitrance is a central test for purely judgmental theories.

Feeling theories

Feeling theories identify emotion primarily with its phenomenal character. Fear is a kind of felt disturbance, grief a felt absence, and joy a felt expansion or lightness.

The view respects the first-person importance of emotion. A purely behavioural or cognitive account appears to leave out what makes anxiety burdensome or delight valuable.

It has difficulty individuating emotions. Bodily arousal can feel similar across fear, anger, excitement, and exercise. Emotions also possess objects and correctness conditions: fear can be unfounded, anger misdirected, and grief appropriate. A bare feeling does not explain these intentional and normative features.

James-Lange bodily theories

William James and Carl Lange proposed that emotion is the perception of bodily changes. We do not tremble because we are afraid; fear is, in an important sense, the felt bodily pattern of trembling, heart rate, breathing, and readiness.

The theory explains embodiment and why emotions alter experience globally. It predicts that changing bodily feedback can change emotion and that impaired interoception should affect emotional differentiation.

Objections include similar bodily profiles across emotions, emotion without strong arousal, and the role of context in interpreting one bodily state differently. Modern embodied theories respond that bodily patterns are dynamic, action-oriented, and integrated with appraisal rather than fixed signatures.

Cognitive and judgment theories

Cognitive theories treat emotions as or as dependent on evaluations. Fear appraises something as dangerous; anger appraises an offence; guilt appraises one's action as a wrong for which one is responsible.

This explains intentionality, rational assessment, and differentiation. Two people with similar arousal can experience different emotions because they construe the situation differently.

If emotions are judgments, recalcitrance is puzzling. A person can fear a harmless spider while judging it harmless. Infants and animals also display emotions without the propositional concepts a strong judgment theory may require.

Appraisal theories weaken the intellectualism. An appraisal can be fast, non-conceptual, and embodied: the environment is registered as significant for needs and goals without an explicit proposition.

Perceptual theories

Perceptual theories compare emotion with perception of value. Fear presents danger, anger presents offence, and admiration presents excellence. Emotion makes evaluative features salient and motivates action.

The analogy explains recalcitrance. A visual illusion can persist despite contrary judgment; fear can continue to present danger despite knowledge of safety. Emotions can therefore supply defeasible reasons without being judgments.

The challenge is whether values are literally perceived or projected through appraisal. Different cultures and histories produce different emotional salience. Perceptual theorists can accept learning and conceptual influence, as ordinary perception is also plastic, but need standards for accurate value perception.

Motivational and action-tendency theories

Emotions prepare action. Fear tends toward escape or vigilance, anger toward confrontation, shame toward concealment, and guilt toward repair. The tendency need not produce overt behaviour; social norms and competing goals can inhibit it.

Action-oriented accounts explain why emotions restructure attention and decision rather than merely add a feeling. They fit embodied and enactive cognition: emotion discloses affordances as threatening, inviting, or blocked.

One emotion can support different actions, and one action tendency can arise from different emotions. Grief has no simple goal-directed response. Motivation is therefore a dimension rather than a complete definition.

Constructionism

Psychological constructionist theories build emotions from more basic ingredients such as core affect, arousal, valence, conceptual categorisation, and situational knowledge. An episode counts as anger rather than fear because a bodily-affective state is interpreted through a learned emotion concept.

Constructionism explains cultural variation, fuzzy boundaries, and the absence of one biological signature for each folk category. It treats emotion words as organising heterogeneous episodes.

The view can overstate conceptual dependence. Infants and animals show patterned affect and action before possessing adult concepts. Cross-cultural variation coexists with biological regularities. A layered theory can combine evolved affective systems with culturally learned categorisation.

Basic-emotion theories

Basic-emotion approaches posit a small set of evolved affect programmes, often including fear, anger, disgust, sadness, happiness, and surprise. Characteristic expressions, physiology, action tendencies, and developmental patterns support the proposal.

Critics challenge universality, one-to-one signatures, and forced-choice methods that may inflate agreement. Emotional episodes are context-sensitive and often blend.

"Basic" can mean evolutionarily ancient, neurally distinct, developmentally early, or psychologically primitive. Evidence for one sense does not establish the others.

Intentional objects

Emotions can be directed at particular objects, events, people, or prospects. Fear of a dog differs from free-floating anxiety; grief concerns a loss; shame may concern how one appears to others.

Some emotions have formal objects: danger for fear, offence for anger, loss for grief. The formal object states the evaluative property under which diverse particulars elicit the emotion.

Objectless moods may represent the world globally as threatening or inviting, or may be affective orientations without determinate accuracy conditions. Their existence prevents one simple object-relation theory from covering all affect.

Fittingness and rationality

An emotion is fitting when its object has the evaluative property it presents. Fear is fitting if danger is present; anger if a genuine offence occurred. Fittingness differs from prudence and morality. Fitting anger may be harmful to express; unfitting hope may be beneficial.

Emotions can be assessed for evidence, proportionality, object, and response. Rationality is not absence of feeling but sensitivity to reasons and revision.

Recalcitrant emotion shows that rational appraisal does not control affect directly. Emotional learning and exposure can alter automatic responses where argument alone does not.

Emotion and reason

The traditional opposition between emotion and reason is misleading. Emotions focus attention, encode significance, motivate inquiry, and reveal stakes. A reasoner without affect may struggle to choose because nothing is salient or valuable.

Emotions can also bias evidence, narrow alternatives, and sustain motivated reasoning. Their epistemic role is therefore defeasible. They are neither irrational intrusions nor automatic perceptions of value.

The action chapter explains how desires and evaluations guide behaviour; emotions add embodied salience and action readiness to that structure.

Social emotions

Shame, guilt, pride, resentment, gratitude, and embarrassment depend on social norms, relationships, and perspectives. Their objects cannot be specified through physiology alone.

The reactive attitudes in moral responsibility register perceived quality of will and structure interpersonal accountability. They are treated normatively in Moral Responsibility.

Social construction does not make these emotions unreal. Institutions and norms are real causal structures; the question is how they combine with evolved affect and individual appraisal.

Assessment

Emotion is best treated as coordinated affective appraisal rather than one hidden ingredient. Phenomenology, body, content, motivation, and social interpretation can dissociate, but a full episode often recruits all of them.
