Who considered the principle of terrestrial unity as the corner stone of human geography and gave the concept of 'Genre-de-Vie' (life style)?

Question

Accepted Answer

Vidal de La Blache is considered the founder of modern French geography and is renowned for his emphasis on the relationship between humans and their environment. He considered the principle of terrestrial unity (the interconnectedness of all things on Earth) as a cornerstone of human geography. He also introduced the concept of "Genre de Vie" (lifestyle), which refers to the functionally related set of habits, practices, and techniques that characterize a particular group's adaptation to its environment. This concept highlights how human societies shape and are shaped by their surroundings. Therefore, Option 4 is the correct answer.

Now, let's explain why the other options are incorrect:

*   **Option 1: Otto Schluter:** Otto Schluter is known for his work on cultural landscapes and his emphasis on the distinction between natural and cultural landscapes. While important in geography, he did not develop the concept of "Genre de Vie" or place the same emphasis on terrestrial unity as the cornerstone of human geography in the way Vidal de La Blache did.

*   **Option 2: Jean Brunhes:** Jean Brunhes was a student of Vidal de La Blache and further developed some of his ideas. While he contributed significantly to human geography, particularly with his focus on human activities and their impact on the environment, the foundational concept of "Genre de Vie" and the emphasis on terrestrial unity as the cornerstone are primarily attributed to Vidal de La Blache. Brunhes built upon La Blache's work, but La Blache originated these core ideas.

*   **Option 3: Albert Demangeon:** Albert Demangeon was another prominent French geographer who contributed to regional geography and rural studies. While he explored human-environment interactions, his work did not center around the concept of "Genre de Vie" or the principle of terrestrial unity in the same fundamental way as Vidal de La Blache's. His contributions were more focused on specific regional studies and the analysis of rural landscapes.
