In this episode of Hunger for Wholeness, Sr. Ilia Delio engages neuroanthropologist Terrence Deacon. Together, they probe the paradox of presence and absence—how constraint, incompleteness, and time shape mind, language, and the emergence of human meaning. From Charles Sanders Peirce to Claude Shannon, Deacon traces a lineage that reframes form not as what’s added, but as what’s held back.

What happens when we privilege what’s present while ignoring the creative force of what’s missing? How does constraint give rise to information, and why might Gödel’s incompleteness illuminate consciousness more than mechanism alone? Moving through Descartes’ split of mind and matter, Deacon proposes that what we call “the mental” is the constraint-aspect of the physical—a shift that dissolves false dualisms and re-roots knowing in embodiment.

Later in the episode, Sr. Ilia and Deacon explore symbolic abstraction, culture, and ecology—how our ungrounded representations both empower and endanger us. They close by examining today’s so-called “artificial intelligence,” arguing it’s better understood as a simulation of intelligence, and asking what a grounded, value-aware future might require of us.

ABOUT TERRENCE DEACON

“Almost everything we do is with respect to something that doesn’t yet exist… All of our actions… are really about that absence. I actually think that this is the essence of what it means for something to be alive.”

Professor Terrence Deacon is Distinguished Professor emeritus at the University of California, Berkeley, and has previously held faculty positions at Harvard University, Harvard Medical School, and Boston University. His research in comparative and developmental neuroanatomy has focused on the human brain, using physiological, quantitative, and cross-species methods. He is the author of The Symbolic Species: The Coevolution of Language and the Brain (1997), which explores how language and the human brain evolved together, and Incomplete Nature: How Mind Emerged from Matter (2012), which examines how thermodynamic, self-organizing, semiotic, and evolutionary processes gave rise to life and mind. He is currently working on a new book, Falling Up: How Inverse Darwinism Catalyzes Evolution, which explores how the relaxation of natural selection and subsequent degenerative processes have paradoxically contributed to the evolution of increasing biological complexity.
