Vom Geist der Gesetze
In "The Spirit of the Laws", Montesquieu outlined the view that man and societies are influenced by climate. He believed that hotter climates create hot-tempered people and colder climates aloof people, whereas the mild climate of France is ideal for political systems. Considered as one of the founders of French geopolitics, Élisée Reclus, is the author of a book considered as a reference in modern geography (Nouvelle Géographie universelle). Alike Ratzel, he considers geography through a global vision. However, in complete opposition to Ratzel's vision, Reclus considers geography not to be unchanging; it is supposed to evolve commensurately to the development of human society. His marginal political views resulted in his rejection by academia.
