Within the depth-psychology and phenomenological corpus, 'gesture' occupies a contested intersection of motor theory, communicative theory, and embodied cognition. Gallagher's sustained analysis — drawing on Ian Waterman's neuropathy and McNeill's gesture-speech synchrony research — establishes gesture as an 'expressive movement' irreducible to either pure body-schema motor control or disembodied linguistics, positioning it instead as a prenoetic performance where cognitive, semantic, and pragmatic factors govern timing and morphokinesis. Merleau-Ponty grounds this lineage earlier, insisting that gesture does not signify anger but simply is anger, collapsing the sign-referent gap and making gesture a direct disclosure of lived intentionality. Nietzsche pushes further still, contrasting gesture — which he regards as bound to the phenomenal world and the genius of species — with musical sound, which dissolves phenomenal limits into Dionysian will. McGilchrist reads gesture neurologically, noting that its metaphoric character originates in the right hemisphere and must be routed for execution to the left, a finding borne out in split-brain patients. Levine locates gesture at the most conscious, voluntary end of a behavioral spectrum that descends into visceral and archetypal registers, warning of the pseudo-feeling quality of volitional gesture deployed without somatic authenticity. Infant-research perspectives in Lanius complicate any simple lateralization account, finding gestural development independent of the linguistic system. Across these positions, the central tension is whether gesture is primarily motor, primarily communicative, or a genuinely hybrid expressive category that reshapes how we understand embodiment, language, and intersubjectivity.
I do not see anger or a threatening attitude as a psychic fact hidden behind the gesture, I read anger into it. The gesture does not make me think of anger, it is anger itself.
Merleau-Ponty argues that gesture is not a sign pointing to a concealed psychic state but is the direct, immediate presence of that state, collapsing the distinction between expression and meaning.

gesture and language are one system. Gestures are movements that occur only during speech, are synchronized with linguistic units, are parallel in semantic and pragmatic functions to the synchronized linguistic units.
Gallagher, citing McNeill, advances the communicative theory that gesture is not a motor supplement to speech but forms with speech a single psychological and semantic structure.

Gesture, as it is activated in the communicative setting, is an expressive movement that is not consciously thought out beforehand... Gesture and language work in a prenoetic manner.
Gallagher categorizes gesture as expressive movement distinct from reflex, locomotive, and instrumental movement, arguing that it shapes cognition prenoetically rather than through conscious control.

the self-organizing intentionality of language remains intact, and gesture, temporarily disrupted by Ian's illness, re-establishes itself to a higher degree than his capacity for instrumental or locomotive movement.
Gallagher uses the case of Ian Waterman to demonstrate that gesture is organized by linguistic-communicative intentionality rather than by the body-schema system that governs ordinary motor action.
, How the Body Shapes the Mind, 2005thesis
Gesture and language shape cognition in a prenoetic manner... gesture is not something that transcends the body in any complete sense. It is inevitably constrained by the requirements of motor control.
Gallagher argues for a dual constraint on gesture: cognitively-communicative factors govern its form and timing, yet motor feedback remains indispensable for sustained gestural performance.

the metaphoric nature of gesture language, in fact, comes from the right hemisphere, and has to be routed across to the left hemisphere for execution.
McGilchrist locates the metaphoric, global-synthetic dimension of gesture in the right hemisphere, identifying a neurological division of labour that is disrupted in split-brain patients.

Gesture helps speakers retrieve words from memory. Gesture reduces cognitive burden, thereby freeing up effort that can be allocated to other tasks.
Drawing on Goldin-Meadow's research, Gallagher demonstrates that gesture serves intra-subjective cognitive functions — reducing memory load and providing access to new thoughts — not only interpersonal communication.

the knitting of the brows intended, according to Darwin, to protect the eye from the sun... become component parts of the human act of meditation, and convey this to an observer.
Merleau-Ponty traces how physiological movements are reorganized under new intentional laws to become culturally meaningful gestures, illustrating the body's capacity to invest movement with figurative significance.

gesture is in a different class of actions than instrumental or locomotive actions... gesture, as a movement concerned with the construction of significance rather than with doing something, is organized primarily by the linguistic-communicative context.
Gallagher distinguishes gesture categorically from instrumental action on the grounds that its organizing principle is significance-construction rather than world-directed doing.

in his gestures he speaks as a satyr... in the intensified language of gesture, in the gestures of dance... When he uses gesture man remains within the limits of the species, which is to say, within the limits of the phenomenal world.
Nietzsche positions gesture as the expressive register of the species-will and the phenomenal world, contrasting it with music as the more primordial vehicle of Dionysian will that dissolves phenomenal limits.
, The Birth of Tragedy, 1872thesis
Language is a modality of the human body. It is generated out of movement. As Merleau-Ponty expressed it, 'the body converts a certain motor essence into vocal form'.
Gallagher frames the chapter's inquiry into gesture by asserting that language, including gesture, is ontogenetically rooted in bodily movement and raises the question of how body schema participates in linguistic generation.
, How the Body Shapes the Mind, 2005supporting
gesture involves a development of successive stages... this is due to the fact that it involves movement and not just semantics... Like movement, gesture is a prenoetic performance.
Gallagher, following McNeill's microgenesis model, argues that gesture is simultaneously a temporal-motoric and a semantic event, its prenoetic character distinguishing it from consciously constructed utterance.

The most conscious behaviors are the voluntary ones: that is, the overt gestures that people generally make with their hands and arms when they are trying to communicate. These movements are the most superficial level of behavior.
Levine places voluntary communicative gesture at the most conscious and superficial end of a behavioral continuum, warning that volitional gestures can convey 'pseudo-feeling' disconnected from genuine somatic states.

When Ian lost control of his movement at the onset of his neuropathy he also lost the ability to gesture... On this view, gestures could be re-established only under conscious control.
Gallagher introduces Ian Waterman's neuropathic loss of gesture as the empirical pivot for testing motor versus communicative theories of gestural control.

Ian, an exceptional case with respect to sensory-motor control, would have consciously to monitor his speech and his gesticulation to keep them in synchrony.
Gallagher presents the motor theory's prediction — that Ian must consciously co-ordinate gesture with speech — as a hypothesis to be weighed against communicative-theory evidence.

my gestures are not reducible to body-schematic processes that are purely instrumental, but are generated in the service of communicative or cognitive processes.
Gallagher summarizes his integrative position: gesture, like body-schematic posture, exceeds purely neurophysiological motor explanation because it is generated in service of pragmatic, communicative, and cognitive ends.

Ian did not gesture at all; his hands remained clasped in his lap... When we assured him that it was safe to move his hands... Ian did gesture.
Gallagher's blind experiment with Ian Waterman demonstrates that gesture depends on proprioceptive feedback for topokinetic precision but retains its morphokinetic and timing properties under communicative motivation.

Animal communication is gestural. It is well known that primates are very sensitive to perceived posture in others... They read meaning into posture and movement; the movement of others, for them, is expressive.
Gallagher extends the analysis of expressive gesture phylogenetically, linking primate sensitivity to posture and movement to the mirror-neuron substrates of shared neural representations.

the gestural system for conveying meaning is an independent meaning-making system... the present research demonstrates the need to consider gestures when evaluating regulatory and interactive behavior.
The Lanius volume presents developmental evidence that infant gesture constitutes an autonomous meaning-making system independent of the linguistic system, with implications for lateralization and early relational regulation.

expressive and regulatory gestures (i.e., other-directed gestures) are asymmetrically organized to the left side of the brain.
Trevarthen's lateralization research, reviewed in Lanius, proposes hemispheric asymmetry in expressive versus regulatory gesture, though the observed variability complicates a clean lateralization hypothesis.

studies on imitation in infants conducted by Meltzoff and Moore (1977, 1983) show that invisible imitation does occur in newborns... newborn infants less than an hour old can indeed imitate facial gestures.
Gallagher invokes neonatal facial gesture imitation to challenge motor-schema accounts of imitation, suggesting that gestural mirroring precedes the formation of explicit body-schema or body-image structures.

Self-directed gestures significantly increased from play episode to still-face and decreased from still-face to the reunion episode... Other-directed gestures significantly decreased from play to still-face.
Infant still-face paradigm data reveal that self-directed and other-directed gestures shift reciprocally in response to relational rupture, situating gesture within early regulatory and attachment dynamics.
