Mind is Matter: Function and Emotion with Paul Thagard
In this episode of See See by Ceci, Paul Thagard, one of the most influential thinkers at the crossroads of philosophy, psychology, and artificial intelligence, takes us on a journey through the architecture of thought, emotion, and coherence that defines the human mind.
A distinguished professor emeritus at the University of Waterloo, Fellow of the Royal Society of Canada, recipient of the Killam and Molson Prizes, and author of eighteen books, Thagard has spent decades asking the hardest questions about intelligence: what it is, where it comes from, and whether machines will ever truly share it with us. His pioneering theory of explanatory coherence reimagines the brain not as a logic machine but as a coherence engine, a system that makes sense of the world by satisfying countless constraints simultaneously, weaving perception, reasoning, and emotion into a single fabric.
In this wide-ranging conversation, Thagard reflects on the difference between intelligence and consciousness; on the devastating role of social media in the spread of misinformation; on the power of analogy as a tool of creativity, from Darwin’s theory of natural selection to the everyday act of reading a stranger’s gesture. And on why computers, despite their cognitive capacities, remain fundamentally psychopathic. “They are highly intelligent,” he says, “but they lack empathy and are therefore incapable of caring.”
That incapacity sits at the heart of the episode’s most urgent theme: the alarming rise of human-AI relationships, and what we risk losing when we mistake imitation for intimacy.
Drawing on his recent book Dreams, Jokes, and Songs: How Brains Build Consciousness and the forthcoming AI Boom or Doom?, Thagard offers a remarkably clear-eyed view of minds both human and artificial, one that is at once scientifically rigorous and deeply humane.
This is an episode about the mind as a coherence engine: hot and cold, rational and emotional, individual and social. About how neurons firing together can produce something as extraordinary as humor, as mysterious as dreams, and as dangerous as political delusion. And about the light, and the peril, that lies ahead as human and artificial intelligence continue to converge.
