The purpose of this communication is to go beyond the logic of growth and depletion, already anticipated by the Physiocrats and Quesnay’s thinking (1765). For him, differing from economic thinking of the time, value can only be created by the land. Consequently, agriculture must not be crushed by taxation. Ahead of his times, Quesnay understood the fundamental role of agriculture and crop rotation. His writings should have inspired the advocates of the tertiarisation of the economy which do not include cycles, the saturation of markets, and are very far from the vision of geographers that necessitates to found some real "social and individual morality". In this particular case, the economy is only the result of the sum of individual behaviours.
