The Whole Person Tastes: What Multisensory Science Reveals About Embodied Experience

Two-thirds of diners at a Milan restaurant wept over a bowl of rice pudding. Not because it was extraordinary rice pudding. Charles Spence, professor of experimental psychology at Oxford, has spent years documenting what made that dish work: a particular emotional arc through the meal, sub-audible vibrations that made diners aware of their own bodies, nostalgic sounds from separate speakers, a wafer broken over the bowl by the waiter. Remove the vibrations, and the rate of weeping drops significantly. Remove the context entirely — hand the same dish to a delivery driver in the hallway — and nobody feels a thing.

Spence calls this a gestalt. Flavor is not a report from the tongue. It is a synthesis assembled across every sense the body possesses, shaped by memory, expectation, and environment. His research has shown that a 15% boost in perceived crunchiness follows from amplifying the high frequencies in the sound of a Pringles bite; that red room lighting increases the perceived fruitiness of wine by roughly the same margin; that the texture of a coffee cup shifts the perceived body of the coffee inside it. None of these factors are in the food. All of them change the food.

For Catholic Christian anthropology, this body of work is not merely interesting. It is structurally important.

Sense, synthesis, and the Thomistic account of perception

Aquinas inherited from Aristotle a careful account of how the senses work together before the intellect ever arrives. The external senses each register their proper objects: color, sound, flavor, odor, texture. But perception of a whole thing requires something more. The classic example is a cube of sugar: the sweetness and the whiteness are delivered by different organs, yet a person perceives them as properties of one thing.

That something is what the tradition calls the sensus communis — the root and principle of the external senses, the capacity in which their separate impressions converge into a single perception of a real object.[^3] The synthetic capacity is passive in relation to the real whole it perceives: the object's unity is given, not constructed.[^1]

Spence's findings map directly onto this architecture. When he played seaside sounds while people ate oysters, the sounds participated in the construction of the perceived flavor-whole. Crossmodal correspondences — the near-universal human intuition that sweetness is high-pitched, bitterness is low and brassy, that angular shapes go with sharp flavors — are not idiosyncratic like synesthesia. They are shared, systematic, and learnable. They are, in Thomistic terms, part of how the sensory composite works.

This corrects a persistent dualist assumption: that the 'real' experience of food is chemical, private, and internal, while everything else is decoration. The person doing the tasting was a whole embodied person, not a receptor array.

The distracted meal and the problem of attention

Spence is direct about eating in front of screens: watching television while eating increases consumption by as much as 30%. His explanation is behavioral — the brain relies on sensory accumulation to register satiation, and distraction interrupts that process. But the anthropological reading runs deeper.

Aquinas's account of the cogitative sense positions this faculty as the interface between sensory experience and rational judgment, making particular objects available to the intellect as meaningful, not merely as stimulus. When attention is divided, the cogitative work of meal-time — registering what one is eating, how it tastes, when enough has been had — is partially suspended. The person is physically present at the table and cognitively absent from the act of eating.

The Ignatian and Carmelite traditions would recognize this as a form of inattention that forecloses experience. John of the Cross's concern with the appetites is not that they are bad in themselves but that when they run without conscious direction, they consume without receiving. Eating more while tasting less is a precise secular example of that dynamic.

Memory, emotion, and the body's participation in knowing

The Milan rice pudding experiment brings forward a feature of the Thomistic account that is easy to understate: the body is not merely a vehicle for experience but a participant in knowing. When the sub-audible vibrations made diners aware of their own bodies while they were already in a nostalgic emotional frame, the tears followed. The body's proprioceptive awareness was not incidental to the emotional response; it was constitutive of it.

The passions are not disturbances to be cleared away before clear thinking can begin; they are part of the apparatus through which the person encounters reality. When a wafer is broken over a bowl and placed in someone's hands in a state of relaxed emotional openness, the action carries weight that purely propositional content cannot replicate. Spence himself notes the possible resonance with Eucharistic ritual — a broken wafer, a prepared emotional state, a communal setting, an effect disproportionate to the object's chemical content.

He does not pursue that observation theologically. But it is worth pursuing here. The Eucharist is precisely not a purely chemical event. It is the most radically multisensory act in the Christian life: bread broken, wine poured, words spoken, incense burned, music sung, bodies kneeling. The tradition has never treated these sensory conditions as auxiliary to the real thing. They are the form in which the real thing becomes accessible to embodied persons.

What the embodied person requires

Spence's practical recommendations are modest: eat with attention, consider the sonic environment of your table, think about what the color and texture of your tableware communicate to your nervous system before the fork reaches your mouth.

The human person does not taste with a tongue any more than a person sees with an eye. Tasting is an act of the whole sensory composite, ordered by attention, shaped by memory and emotion, situated in an environment. Distract that composite, fragment its attention, strip its environment of meaning, and the experience degrades — not just aesthetically but morally, in the sense that a person becomes less present to what they are doing and less capable of the gratitude that attentive eating makes possible.

Spence did not set out to argue for mindful eating as a spiritual practice. He set out to understand why nobody likes a soggy chip. The answer turned out to implicate the full architecture of embodied human cognition. That architecture, for Catholic Christian anthropology, is not an accidental feature of fallen creatures stumbling toward the digital age. It is the created form of the person — a form meant to be inhabited with attention, governed by prudence, and capable, in the right conditions, of being moved to tears by a bowl of rice pudding.
