A "living thing" has an inborn intelligence within its body, called Innate Intelligence.
It is the local intelligence which has built a house for itself and keeps that house in repair, and is the intelligence to which the condition of the structure is of supreme importance.
No one will deny that it requires intelligence to build a body. It cannot be denied that it takes intelligence to build even a tissue cell. No scientist, however clever, has been able to do it and never will, for it is the task for The Infinite.
It must be remembered that infinity is in a tissue cell just as much as in stellar space. It cannot be done by man, no matter how efficient his laboratories are.
The cells and the bodies are built according to a plan. It takes an infinitely wise Architect to make those plans.
Though scientists have studied anatomy and histology for centuries, their knowledge of the body leaves as much unexplored as the Darkest Africa before it was explored.
