mitochondria are the power plants of the cell, but Martin Picard argues that describing them as batteries misses almost everything. In his energetic view of life, these strange organelles, which carry their own DNA and multiply on their own schedule, sit at the junction where biology becomes experience.
The argument begins with a simple observation: every thought, feeling and movement costs energy, and that energy is produced by mitochondria. When demand outpaces supply, the body does not merely slow down, it adapts, reallocating resources and changing how cells behave. Picard proposes that these energetic negotiations, repeated across trillions of cells, help explain why chronic stress leaves lasting marks on health, and why the boundary between mind and body is far more porous than the language of modern medicine suggests.
Not everyone accepts the full scope of the theory, and the experimental program is young. But it has already produced measurable links between mitochondrial function and psychological states, and it offers a rare framework in which metabolism, behaviour and subjective experience can be studied as parts of a single system.
