Abstract
The article analyzes and interprets the feeling of nature in the work of Miguel de Unamuno, within the framework of his poetic philosophy, highlighting his affinity with Rousseau. Selecting and analyzing some of his writings, the feelings of fullness and tranquility that Unamuno experiences in contact with nature are tackled. In his love of nature, personalizing the living, don Miguel found both the joy of living and the peace that it made him recover strength to start new battles. Far from the agonist Unamuno, the analyzed writings reveal the contemplative who enjoys life and experiences its fullness.
