Taste occupies a surprisingly wide conceptual territory in the depth-psychology corpus, functioning simultaneously as a biological sense modality, a philosophical paradigm for discrimination, a neurological substrate of pleasure, and a spiritual-ethical instrument. Aristotle establishes the foundational ontology: taste is the sense most intimately bound to touch, requiring no intervening medium, actualized through the moistening of the organ by a tastable body. Plato’s Timaeus extends this into a cosmological framework, correlating taste with the element water and situating flavour-perception within a broader account of pleasure and pain as soul-events. The Neoplatonic and patristic traditions, represented by John of Damascus, catalogue taste among the five senses as a vehicle of creaturely discrimination. The depth-psychological literature proper introduces two decisive shifts. First, neuroscientists — Panksepp, Berridge, Craig, and Naqvi — locate gustatory pleasure within neural circuitry that dissociates ‘liking’ from ‘wanting,’ identifying the insula as primary taste cortex while relegating hedonic valuation to downstream amygdalar and orbitofrontal regions. Second, the somatic-psychological tradition (Ogden, Levine, Hillman) reclaims taste as a grounding sense capable of anchoring present-moment awareness, regulating affect after trauma, and — in Hillman’s arresting formulation — intensifying paradoxically even as peripheral acuity wanes in old age. Easwaran imports the Gita’s sattva/rajas/tamas framework to argue that compulsive taste-orientation contracts consciousness into the palate and enslaves the will. McGilchrist adds a hemispheric dimension, noting that basic tastes derive from the tongue while all complex flavours are olfactory, with right-hemisphere dominance for sensory discrimination. The etymological stratum, accessed through Onians, reveals that Latin sapere — to have flavour — is the root of sapientia, wisdom: taste is not merely appetite but the archetype of discernment itself.
Its original meaning was ‘to be flavoured, have flavour’… It was then transferred to the taster so as to mean ‘to have the faculty of taste’ and thence ‘to have discrimination’, ‘to be wise’.
Onians argues that Latin sapere grounds the concept of wisdom etymologically in gustatory flavour, making taste the primordial metaphor for intellectual discernment.

The insula has been identified as the primary taste cortex… It appears that the insula represents stimulus properties, such as the intensity or identity of a taste, as opposed to its hedonic value, which appears to be processed in downstream regions.
Naqvi establishes that the insula encodes the identity and intensity of taste as a sensory fact, while pleasure or aversion is computed separately in the amygdala and orbitofrontal cortex.

We will need to understand the pleasurable nature of certain tastes and the distressful nature of hunger to fully grasp the overall pattern of energy regulatory processes in the brain. At present, we do not know where gustatory pleasure is mediated in the brain.
Panksepp frames gustatory pleasure as an unresolved but central problem for affective neuroscience, implicating septal, amygdalar, and brainstem regions without assigning priority to any.

taste too is of the tastable and the untastable… the tastable is moist, it is necessary that the organ for it be neither moist in actuality nor incapable of becoming moist. For the taste is affected in a way by the tastable insofar as it is tastable.
Aristotle defines taste as the sense actualized by moisture, requiring an organ that is potentially but not actually wet — the foundational account of taste as passive receptivity.

What can be tasted is always something that can be touched, and just for that reason it cannot be perceived through an interposed foreign body, for touch means the absence of any intervening body.
Aristotle demonstrates that taste is structurally identical to touch in requiring direct bodily contact, differentiating it from the mediate senses of sight, hearing, and smell.

Only sattva knows the real taste of food; rajas obliterates the taste with conditioned preference, while tamas renders one insensible to it altogether.
Easwaran uses the Gita’s three-guna framework to argue that the quality of consciousness determines whether taste is experienced as genuine sensation or merely habituated craving.

We can spin out from one wild strawberry a whole northern summer, from one tasty tea cake a vast French novel. The sensuous acuity remains, but has become detached from the senses. It is now more literary and less literal.
Hillman argues that in late life taste as peripheral sensation attenuates while taste as imaginative resonance intensifies, inverting the common assumption about sensory decline.

People who are highly taste-oriented, for example, are extruding their palate farther and farther… they squeeze all their consciousness into their taste buds; they are feeling the world through the palate.
Easwaran argues that exclusive identification with gustatory sensation contracts and destabilizes consciousness, making the control of the palate a primary discipline of inner freedom.

Even newborn babies react distinctly to the four intrinsic gustatory qualities. They pucker their lips and squint their eyes in response to sour flavors… They exhibit a concerned look and pull away from the taste of salt.
Panksepp cites neonatal facial responses to the four basic tastes as evidence that gustatory affect is innate and pre-experiential, preceding cultural conditioning entirely.

Galen suggests that the four other senses correspond to the four simple bodies: sight to fire, hearing to air, taste to water, touch to earth.

the tongue is used both for tasting and for articulating; in that case of the two functions tasting is necessary for the animal’s existence (hence it is found more widely distributed), while articulate speech is a luxury subserving its possessor’s well-being.
Aristotle ranks taste as biologically primary — necessary for survival — while articulate speech is secondary, revealing a hierarchy that aligns with depth-psychology’s interest in somatic primacy.

External sense organs transmute physical stimuli and convert them into nerve impulses registering sight, hearing, touch, taste and smell. Ubiquitous internal sensors monitor a multitude of physiological and visceral processes and sort them into comfortable and uncomfortable.
Levine situates taste among the external senses within a broader interoceptive-exteroceptive schema, arguing that the hedonic sorting of all sensation constitutes the crucible of feeling.
