Nowadays, we are nothing but our brains. Whereas we used to be composed of the intangible and unknowable secrets of mental or spiritual life, now we insist on the mechanistic materiality of the physical brain as the site of human being. This is the argument of Jan De Vos in his book Metamorphoses of the Brain, who describes the ongoing process of “neurologization” in which the brain has become the scientific and cultural obsession of our times. We celebrate the brain as the seat of humanity’s supposed intellectual superiority: a bio-chemical marvel of invention, imagination, and memory.
