Rethinking Reason: How Neuroscience Upends Our Enlightenment-Era Understanding of Human Thought
{by Dr. George Lakoff, author of "Metaphors We Live By"}
A groundbreaking perspective emerging from cognitive science and neuroscience is challenging the very foundation of Western philosophy: the Enlightenment model of reason. This new paradigm argues that human rationality is not the conscious, logical, and disembodied process it was long believed to be. Instead, research reveals that our thought is fundamentally embodied, unconscious, and metaphorical.
The evidence for this shift is robust. Neuroimaging studies show that the same brain regions activate when performing an action, imagining it, or seeing it performed, a discovery attributed to mirror neuron systems. This provides a biological basis for empathy and learning through simulation. Furthermore, clinical cases demonstrate that patients with emotional impairments cannot make rational decisions, proving that emotion is not opposed to reason but essential to it.
Our understanding is structured by "frames," mental models that give context to concepts. Every word is defined within a frame, and negating a frame, ironically, reinforces it. We also rely on "conceptual metaphors," unconsciously mapping physical experiences (e.g., warmth, journeys) onto abstract ideas (e.g., affection, life). Empirical studies in embodied cognition confirm this link; holding a warm drink literally makes us judge others as warmer and more friendly.
The implications are vast. This explains why mere facts rarely change deeply held beliefs—if information doesn't fit an existing frame, it is rejected. This neural reality influences everything from political discourse and effective communication to marketing and artificial intelligence, urging a reevaluation of what it truly means to think.
If you're interested in diving deeper, his most famous books on this topic are:
- Metaphors We Live By (with Mark Johnson) - The classic introduction to conceptual metaphor.
- Women, Fire, and Dangerous Things - A deeper dive into categorization and cognition.
- The Political Mind - Applies these concepts directly to politics.
- Where Mathematics Comes From (with Rafael Núñez) - Applies embodied cognition to the seemingly abstract world of math.
