Should emotion terms refer to feelings or to motive states?

Raised by Scarantino (2018), a commentary on LeDoux (2012) in a themed issue LeDoux himself co-edited.

Why this is worth a page rather than a footnote

The wiki’s other emotion debates are about the world: do categories map to circuits (locationist-vs-constructionist-brain-emotion), where are feelings constituted (where-are-feelings-constituted), can we know what animals feel (can-we-know-animal-feelings). This one is about the vocabulary — and its interest lies in Scarantino’s demonstration that a dispute which looks like the other three is almost entirely this one.

Set the two frameworks side by side on defense, as his figure does:

subcortical motive mechanismfelt state
LeDouxdefense survival circuitfear
Scarantinobasic fearfeeling of fear
Mobbsreactive fearcognitive fear

The box-and-arrow flow underneath is identical — threat → sensory system → subcortical defensive circuit → (reflex-like responses ∥ cognitive circuit) → instrumental defensive behaviour. Only the labels differ. Scarantino prints them in red to make the point unmissable.

The agreement is the finding

Before the disagreement, the shared ground, which is extensive and which the wiki should not lose sight of:

  • Adaptive behaviour and feelings are implemented by different circuits. Both reject Panksepp here. This is the load-bearing premise: without it there are not two things to name.
  • A global motive state is reflexively generated, instantiated in preparatory physiology and brain arousal — LeDoux’s defensive organismic state, Scarantino’s activated basic fear, Mobbs’ activated reactive fear.
  • That state need not be felt.
  • A general-purpose cognitive system regulates it into instrumental rather than merely reactive behaviour — Gallistel’s (1980) two-level control structure. Cortical regulation is what makes the circuit adaptive.
  • Feelings arise via higher-order representation in cortical networks. See higher-order-theory-of-consciousness.

Scarantino’s title question — are survival circuits basic emotions under a different name? — gets the answer nearly. The residue is real but small, and he flags it precisely: “LeDoux is more tentative than I am in granting the defensive organismic state causal powers over behavior.” That is the one substantive disagreement visible in the paper, and neither author develops it. If this debate has an empirical discriminator, that is where it lives — does the global motive state cause behaviour, or merely accompany it? Nothing in the wiki’s current sources tests it.

The real disagreement: what is emotion science for?

Beneath the labels, a difference about the explanandum:

  • LeDoux: the central task is explaining how feelings come about.
  • Scarantino: the central task is explaining how emotions motivate behaviour.

Each then reserves the good word — “fear” — for his own explanandum. Read this way, the terminological fight is a proxy for a disciplinary priority claim, and neither author argues directly for his priority.

Historical note recorded on both study pages: LeDoux used to hold both tasks, distinguishing implicit emotions (motive states) from explicit emotions (states of consciousness) in The Emotional Brain (1996) and Synaptic Self (2002). He abandoned the distinction not because it was incoherent but because it did not survive contact with readers. Scarantino’s whole commentary can be read as an attempt to talk him out of that surrender.

Does common sense get a vote?

The sharpest exchange, and the most portable beyond emotion science.

LeDoux’s argument is sociological: the gravitational pull of common sense is strong enough that a technical usage of “fear” for a nonconscious motive state will be misread, and was misread — his own amygdala work got reported as showing where feelings of fear come from. Given that, the scientifically responsible move is to stop fighting the tide.

Scarantino’s rebuttal has three parts, of uneven strength:

  1. Common sense is not univocal. Folk psychology explains behaviour by emotions — “Maria slapped Lucas because she was angry,” “Tom shot the bear because he was afraid” — where emotions are latent causes, not experiences. So LeDoux’s premise (common sense identifies emotions with feelings) overstates a mixed record. Offered without usage data.
  2. Common sense shouldn’t legislate. Quine: there are no conceptual truths in science; even the Euclidean assumption that parallels never meet was abandoned for a better physics. “Why should the affective sciences be the exception to this rule, and allow common sense to make the identification of emotions with feelings true by definition?” The Pluto analogy: lay confusion at the 2006 demotion is no argument against the astronomers’ definition. The one reply that is actually argued, and the strongest.
  3. The pragmatic argument may run backwards. If the field has already moved away from identifying emotions with feelings, then LeDoux’s convention is the more misleading one — a reader who takes “fear” to mean the feeling will read LeDoux’s cortical results and “mistakenly conclude that LeDoux has shown that the motivational system which evolved to deal with dangers is cortically implemented.” Supported by the Ekman/Damasio/Scherer/Russell survey above, which is the paper’s strongest evidence-like contribution.

Note what reply (2) costs him: if common sense has no authority, it cannot ground his own preference either — and Scarantino says so. “My own account presupposes that there are good arguments for assimilating emotions with motive states exclusively. My point is that none of such arguments should rely on common sense.” The debate is thereby handed to fruitfulness: which conceptual scheme yields better science? Neither author demonstrates his scheme wins on that criterion, which is why this stays open.

The unanswered objection

Recorded because the paper does not confront it. If the problem is that readers cannot hear “fear” without hearing the feeling, then “basic fear” inherits the problem — the word fear is still in it. Scarantino’s implicit reply is that explication makes the qualifier do the work, as it did for short-term memory. But whether readers honour the qualifier is exactly the empirical claim LeDoux is making, and Scarantino answers it with an analogy rather than evidence.

Against that, LeDoux’s neologisms have their own cost, which Scarantino does not press but which the wiki can note: defense survival circuit is unambiguous but severs the construct from a century of literature indexed under “fear,” including the autonomic-specificity-of-emotion and basic-emotions material this wiki already holds.

Status: open

Open, and possibly dissolvable rather than resolvable — a candidate for status: dissolved if a future source shows the two frameworks make no divergent predictions. Two things block that verdict for now:

  1. The causal-powers asymmetry above (does the motive state drive behaviour?) is a genuine empirical difference, unnoticed by both authors as such.
  2. Scarantino and LeDoux disagree about what a good scientific category is, not just what to call it — HPC kinds with no essences (homeostatic-property-cluster-kinds) versus circuits individuated by evolved function (survival-circuits). Those are different metaphysics, and they could come apart on cases even where they agree on defense.

Flagged for a human: this is the wiki’s clearest instance of a dispute where the neuroscience is shared and the fight is over words — worth deciding whether the wiki adopts a house convention. Every existing page uses LeDoux’s vocabulary, because the LeDoux ingest came first.
