Pneuma
The Greek concept of breath, spirit, and vital force — the animating substance that connects body, soul, and cosmos.
The Meaning of Pneuma
Pneuma was breath, and breath was life. When a person died, the pneuma left the body — the last exhalation was the departure of the life force. But pneuma was far more than a metaphor. Stoic physics made it the active principle of the entire cosmos. Pneuma permeated all matter as a continuous, intelligent tension that held things together and gave them their properties. A stone had pneuma that made it hard. A plant had pneuma that made it grow. An animal had pneuma that gave it motion and sensation. A human had pneuma that produced reason. Galen, the great physician, identified three types of pneuma in the body: natural pneuma produced in the liver, vital pneuma produced in the heart, and psychic pneuma produced in the brain. This pneumatic physiology dominated medicine for fifteen centuries. The Stoic idea of cosmic pneuma influenced early Christian theology profoundly — the Holy Spirit is pneuma hagion in Greek, and the early Church Fathers debated how much Stoic physics to incorporate into their theology. The connection between breath, spirit, and life force remains embedded in language itself.
