What Le Guin is expressing is a beautiful idea, but it is a false beauty. It feels like truth because it aligns with how narrative engages the human mind, not because it accurately explains what stories are or why they exist. The sense that fiction reveals destiny, inner depth, or essential humanity is an illusion created by evolved cognitive machinery, not evidence of genuine insight.
From an evolutionary and cognitive standpoint, imaginative fiction is not a privileged tool for understanding who we are. It is a byproduct of more basic adaptations. The human brain evolved as a prediction engine optimized for survival in social groups. Its primary function is to anticipate outcomes, model other agents, and reduce uncertainty well enough to reproduce. Narrative arises because the brain naturally organizes experience into causal sequences involving agents, not because stories convey deeper truths about the self.
Fiction works by hijacking the same neural systems used for social reasoning, memory, and planning. When reading a story, the mind runs simulations of social situations. This feels like insight, but feeling insight is not the same as acquiring accurate models of reality. Fantasy and science fiction are not special forms of wisdom. They are simply inputs that exaggerate certain variables, making simulations emotionally vivid rather than epistemically reliable.
Le Guin’s claim that someone without stories would be ignorant of their emotional or spiritual depths is not supported by biology. Emotions are not learned through narrative. They are innate regulatory systems shaped by natural selection. Fear, attachment, anger, desire, and joy exist prior to language and independently of story exposure. Stories can name, frame, or intensify these states, but they do not create or deepen them in any fundamental sense.
The universality of storytelling also does not imply that it is an adaptive route to understanding. Evolution does not favor truth or self knowledge. It favors fitness. Many of the most persistent stories humans tell are systematically false. Myths, religious narratives, romantic ideals, and national legends endure because they exploit cognitive biases like agency detection, pattern completion, and emotional salience. Their spread demonstrates susceptibility, not insight.
Fantasy and science fiction do not teach us to imagine better worlds. They teach us to imagine compelling ones. A narrative can feel profound while being completely disconnected from reality. Inspiration and accuracy are orthogonal. The persuasive power of stories comes from their alignment with evolved psychological vulnerabilities, not from their correspondence with truth.
So the correct technical framing is this. Stories are not tools invented to gain understanding of humanity or destiny. They are artifacts produced by brains shaped for survival under uncertainty. They can be pleasurable, motivating, or culturally stabilizing. They can sometimes illuminate patterns of behavior. But their beauty should not be confused with truth. The feeling of depth they produce is an illusion, not a discovery.
