Editors' note: The Earth is a three-brained being. The whole face of the globe is the moving-instinctive brain of the Earth, the North Pole is the intellectual centre and the South Pole the emotional centre. Gurdjieff describes the intellectual brain as Great Nature. The intellectual part of nature is the equalising factor which balances the emotional and moving centres. For example, if the Earth wants more people to exist it increases the population by decreasing wars, famine, earthquakes and disease. If it wants less, the converse applies. The intellectual part of the Earth controls the law of accident pertaining to mankind.
