A termite colony is not a society of individuals but a single organism whose organs happen to be physically separate. The queen functions as brain and reproductive center, workers and soldiers as mobile cells, and the mound itself as body and skin. The proper unit of biological analysis is therefore the whole termitary, not the single insect.
Marais drove a steel plate through a termitary, cutting it into two sections with the queen on one side. Workers on both sides repaired their breaches in coordinated, matching structures even though they had no physical contact. When the queen was killed, coordinated work stopped across the whole mound, which he took as evidence that a central influence directed the colony at a distance.
If each termite is treated as a cell rather than an agent, questions about individual intelligence or motive become misframed. A blood cell does not understand healing, yet healing happens. In the same way, purposive behavior such as building, defense and repair belongs to the colony-level organism and not to any single insect.
Marais proposed that the colony has a collective mind, a 'group soul', centered on the queen. It integrates the behavior of blind, scattered workers much as a nervous system integrates the body. Destroying the queen does not just remove one member but kills the organism's coordinating psyche, leaving behind a living but aimless mass.
The termitary's architecture is an organ that serves the whole organism. Its ventilation shafts, sealed walls and fungus gardens regulate temperature, humidity and digestion the way tissues regulate a body. When the mound is breached, the response looks like wound-healing: soldiers guard the gap while workers seal it, restoring the organism's internal environment.
Working alone in the Waterberg, writing in Afrikaans and struggling with morphine addiction, Marais reached the superorganism view independently of, and in parallel with, contemporaneous ant research of around 1911. He did not reach it before that research. Because he published in a minor language and far from scientific centers, his observations were absorbed without adequate credit into a celebrated 1926 French book on termites. Recognition often follows language and network rather than originality.
