Within the depth-psychology and neuropsychological corpus, the right hand functions as a nexus where neuroanatomy, symbolic theology, and phenomenology converge. At the neurological level — most fully elaborated in McGilchrist's twin volumes — the right hand is controlled by the left hemisphere and serves as its primary instrument of manipulation, tool-use, and linguistic gesture. The impairment of the right hand following left hemisphere stroke reveals not merely motor deficits but a deeper cognitive loss: the capacity to utilise familiar objects purposively. This connects right-handedness structurally to language, as Broca's area and the gesturing right hand are contiguous neuroanatomically and functionally inseparable. McGilchrist further notes that in split-brain patients, gesture from the right hand becomes abstract and impoverished, exposing the hand's dependency on the left hemisphere's decontextualised, categorical mode of engagement. In a radically different register, Jung's Aion identifies the right hand with divine mercy, redemptive power, and salvific grace in midrashic exegesis, contra the left hand's judicial severity. Jonas likewise locates the right hand in Manichaean cosmology as the rescuing gesture of the Living Spirit. The term thus spans the empirical and the symbolic: as bodily instrument of the grasping intellect on one pole, and as cosmic sign of redemptive power on the other.
God's love and mercy are named his right hand, but his justice and his administration of it are named his left hand… 'When the children of Israel perform God's will, they make the left hand his right hand.'
Jung marshals midrashic sources to establish that the right hand is the theological symbol of divine mercy and salvific grace, while the left hand signifies justice and accusation.

In left hemisphere damage, the two most serious consequences are motor impairments, particularly of the right arm and hand; and language impairments. Let's begin with the right hand.
McGilchrist argues that the right hand and language share a common left-hemisphere substrate, and that damage to that hemisphere reveals the right hand's role as the primary cognitive instrument of purposive tool-use.

most are made by the right hand — since speech and gesture are so closely combined in and near Broca's area — 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 demonstrates that although gesture is physically executed by the right hand under left-hemisphere control, its metaphoric richness originates in the right hemisphere, revealing the hand as a contested site between the two modes of mind.

from the hellish substances by the Living Spirit who descended and extended to him his right hand, and ascending he became a God again.
Jonas identifies the right hand in Manichaean myth as the salvific gesture of the Living Spirit, making the extended right hand the cosmic archetype of redemption and liberation from matter.

Q: Mrs M, point to my student with your right hand. A: [Patient points.] Q: Mrs M, point to my student with your left hand. A: [Patient remains silent.] Q: Mrs M, why are you not pointing? A: Because I didn't want to.
Clinical evidence from Ramachandran's patient illustrates the phenomenological dissociation between right-hand compliance and left-hand alienation following right hemisphere damage, indirectly confirming the right hand's normalised integration with self-awareness.

The metaphor of grasp has its roots deep in the way we talk about thinking in most languages… In German the notion of 'handeln' embraces all meaningful and goal-directed human activities. It characterises unequivocally the total personality of man.
McGilchrist, drawing on Révész, links the right hand's grasping action etymologically and conceptually to the left hemisphere's mode of engaging the world through manipulation, comprehension, and purposive activity.

patients with brain lesions in the right hemisphere find this extremely difficult… the right hand often cannot succeed at all in putting the design together with the blocks. The left hand, in a sense the hand of the gods, has no problem whatever.
Jaynes contrasts the right hand's failure at synthetic spatial tasks with the left hand's facility, and mythologises the left hand as 'the hand of the gods,' implicitly casting the right hand as the instrument of the analytic, verbal, mortal self.

The only way we know that the right hemisphere has this information at all is to ask the right hemisphere to use its left hand to point it out — which it can readily do.
Jaynes uses split-brain data to distinguish right-hand responses (reflecting left-hemisphere verbal knowledge) from left-hand responses (reflecting right-hemisphere tacit knowledge), situating the right hand as the instrument of conscious, linguistic selfhood.

Because it is concerned with the intellect, the spiritual law is represented by the olive tree on the right: it imbues sense-perception with the spiritual principles of created things and makes conduct purposive and intelligent.
In the Philokalic tradition, the right side is aligned with intellect and spiritual law, mirroring the wider symbolic convention in which the right hand represents the higher, purposive, and divine faculty.

I wear a glove on my right hand, which is the hand with which I am going to draw. The task is very simple and I perform it without difficulty on the first three trials.
Gallagher uses the right hand as the default instrument of intentional action in a proprioceptive illusion experiment, treating it phenomenologically as the normative agent-hand whose sense of ownership and agency can be experimentally dissociated.

feeding is guided by use of the right eye, which projects to the left hemisphere. A chick with its right eye covered has difficulty finding food particles to eat on the ground.
Craig's ethological evidence of left-hemisphere dominance for routine feeding behaviour in vertebrates provides an evolutionary context for the right-hand/left-hemisphere coupling central to the broader argument.
