The "Men without Chests" — Symbol of Moral Emptiness (Personal and Philosophical Symbol)
Lewis's most striking image, "Men without Chests," represents individuals whose moral and emotional faculties have been hollowed out by flawed education. Drawing inspiration from Plato’s tripartite model of the soul, Lewis identifies:
-
The Head as the seat of reason,
-
The Belly as the source of primal desires, and
-
The Chest as the mediator of right emotion and conscience.
When education dismisses moral sentiment as subjective, it effectively removes the "chest." The result is an intelligent yet emotionally sterile generation—capable of reasoning but devoid of virtue. These "men" are vulnerable to manipulation, as their intellect operates without moral restraint.
The Tao — Symbol of Universal Moral Law (Metaphysical Symbol)
The Tao, a term borrowed from Chinese philosophy meaning "The Way," becomes Lewis's symbol for the eternal moral order underpinning all human civilizations. For Lewis, the Tao is not bound to any single religion or culture; it is the collective moral compass evident in traditions from ancient Greece to Hinduism.
Rejecting the Tao, therefore, means rejecting the very foundation of value judgment. Any attempt to create new ethics outside its framework collapses into arbitrariness and moral confusion. The Tao thus symbolizes the unchanging moral truth that safeguards humanity’s spiritual coherence.
The Green Book — Symbol of Corrupt Pedagogy (Cultural and Educational Symbol)
Lewis introduces The Green Book, an anonymous school textbook, as a representation of the distorted educational ideologies of modernity. The book teaches that evaluative statements—such as calling a waterfall "sublime"—reflect only personal feelings rather than objective truths.
By teaching children that emotions are merely subjective, such education erodes the capacity for genuine moral response. The Green Book, therefore, stands as a symbol of intellectual conditioning that breeds skepticism toward virtue and prepares the ground for moral relativism.
The "Conquest of Nature" — Allegory of Misguided Progress (Philosophical Allegory)
Lewis's portrayal of humanity's "conquest of nature" serves as a powerful allegory for the misuse of scientific and technological progress. What appears as mastery over the natural world is, in truth, domination of some humans by others who control the instruments of power.
The irony lies in the fact that every victory over nature reduces man's own freedom, binding him to his own inventions. The allegory ultimately warns that in the quest to control everything—even human nature—mankind risks becoming the very object of his own domination.
The Conditioners — Allegory of Dehumanization (Political and Ethical Allegory)
The Conditioners represent the final stage of moral decay: a class of individuals who wield total psychological control over humanity. Having abandoned the Tao, they possess no objective standard to guide their decisions. Their manipulation of human nature for personal or ideological ends reveals the tragedy of absolute relativism—when power exists without principle, and creators become slaves to their impulses.
The Peril of "Seeing Through" — Motif of Intellectual Skepticism
A recurring motif in Lewis's essay is the modern obsession with "seeing through" everything—questioning every value and exposing every belief. Lewis compares this to looking through a window: if one keeps seeing through, one never sees what is outside.
This motif represents epistemological blindness—a state where excessive skepticism destroys the capacity to perceive truth. Once every value is "seen through," nothing remains to be believed, and vision itself becomes meaningless.
Moral Irony — Motif of Self-Contradiction
Lewis repeatedly employs irony to highlight the absurdity of a culture that destroys virtue yet demands virtuous conduct. His metaphor of "castrating and bidding the geldings be fruitful" captures this contradiction perfectly: society discards moral formation while still expecting integrity, courage, and empathy.
Similarly, the pursuit of power through science without moral grounding becomes self-defeating—power without principle leads not to progress but to moral collapse.
