Host: Dr. Juan Carlos Rey
Episode: Interlude XXVIII - Metaphor as Neural Bridge: How Meaning Crosses from Body to Mind
Date: December 17, 2025
In this thought-provoking interlude, Dr. Juan Carlos Rey explores the fundamental role of metaphor in human cognition. Moving beyond poetic language, he discusses groundbreaking research revealing how metaphors are rooted in bodily experience, not just as a way of speaking but as a way of thinking and being. The episode traverses insights from influential linguists, neuroscientists, and psychologists, challenging listeners to examine how metaphorical language shapes perception, emotion, and identity at a neural level.
Key Discussion Points & Insights
1. Metaphor’s Profound Role in Thought (00:02–03:02)
- Dr. Rey opens by questioning the boundaries between figurative and literal language, asking: "Is metaphor merely decorative language? Or is it the mechanism through which human consciousness organizes meaning?" (00:17)
- Reference to Lakoff & Johnson's "Metaphors We Live By" which claims that “metaphor is not an ornament of thought, it is thought.” (01:04)
- Abstract reasoning consistently recruits bodily experience:
- Time is movement
- Emotion is temperature
- Understanding is grasping
- Morality is vertical orientation
- “These patterns are not poetic coincidence. They are cognitive structure.” (01:35)
- Abstract reasoning consistently recruits bodily experience:
2. Scientific Evidence for Embodied Metaphor (03:03–05:25)
- Raymond Gibbs’s experiments: Participants reading phrases like “grasp the concept” or “push the argument aside” showed activation in their motor regions.
- “The brain did not treat metaphor as symbolic substitution. It treated it as embodied simulation.” (03:48)
- “Language did not describe experience. It attempted to reenact it.” (04:01)
- Jerome Feldman’s computational neuroscience models:
- Abstract reasoning reuses neural circuits evolved for perception and movement.
- “The brain does not invent meaning from nothing. It attempts to recycle wherever possible. Concepts borrow structure from sensation. Reason borrows scaffolding from action. Meaning travels across neural bridges built by the body.” (04:31)
3. Metaphor and Social Connection (05:26–06:31)
- Vittorio Gallese’s work: Shared metaphors synchronize social understanding, aligning us neurologically and linguistically.
- “Empathy, narrative persuasion, and moral resonance all depend on this shared corporeal mapping. We do not merely understand one another through words. We coordinate through felt structure.” (05:56)
- Examples: Political language, religious imagery, therapy, and self-talk all rely on metaphorical “architecture.”
- “If life is framed as battle, the nervous system prepares for conflict. If it is framed as journey, endurance emerges. If it is framed as burden, fatigue will follow.” (06:15)
4. Conscious Use and Dissolution of Metaphor (06:32–07:52)
- Most metaphors are unconscious; rarely do we select them intentionally.
- “The observable unknown is not metaphor itself. It is how rarely we choose it consciously.” (06:32)
- In meditation, ritual, and trance states, metaphor sometimes fades away. Practitioners report “direct sensation without narrative overlay.”
- Neuroimaging shows that in these states, “reduced linguistic mediation and increased sensory coherence” occur (07:09).
- “When metaphor falls silent, perception sharpens. When it returns, meaning condenses. Language becomes much more a lens than a prism.” (07:19)
5. The Transformative Power of Metaphor (07:53–End)
- Changing metaphors = changing neural wiring; it’s not just a cosmetic shift but a “neurological revision.”
- “If metaphor structures thought and thought structures identity, then changing metaphor is not merely cosmetic, it is neurological revision.” (07:54)
- “Human freedom may lie not in abandoning language but in learning how language shapes us from the interior.” (08:03)
- Closing reflection:
- Dr. Rey encourages listeners to notice the metaphors they use internally:
- “What weight do they carry? What motion do they imply? What posture do they ask your nervous system to assume?” (08:18)
- Invitation for listener reflection and contact.
- Dr. Rey encourages listeners to notice the metaphors they use internally:
Notable Quotes & Memorable Moments
- On the true nature of metaphor:
- "Metaphor is not an ornament of thought, it is thought." (01:04, paraphrased from Lakoff & Johnson)
- On experiment results:
- “The brain did not treat metaphor as symbolic substitution. It treated it as embodied simulation.” (03:48)
- On everyday consequences:
- “If life is framed as battle, the nervous system prepares for conflict. If it is framed as journey, endurance emerges. If it is framed as burden, fatigue will follow.” (06:15)
- On identity and metaphor:
- “If metaphor structures thought and thought structures identity, then changing metaphor is not merely cosmetic, it is neurological revision.” (07:54)
- On human freedom:
- “Human freedom may lie not in abandoning language but in learning how language shapes us from the interior.” (08:03)
- On mindfulness of language:
- “Notice the phrases you use to describe your inner life. What weight do they carry? What motion do they imply? What posture do they ask your nervous system to assume?” (08:18)

Concluding Thoughts
Dr. Rey’s interlude offers a powerful lens for understanding how deeply metaphor pervades not just our language but our neural functioning and sense of self. Listeners are left with a call to investigate the metaphors guiding their inner narratives—suggesting that such conscious engagement might open pathways to new forms of freedom, perception, and identity. The episode balances rigorous science with poetic resonance, perfect for those seeking to bridge the gap between the measurable and the mystical.
