Miguel de Unamuno (1864-1936) is best known in the contemporary world, perhaps, for his book Del sentimiento trágico de la vida en los hombres y en los pueblos (On the Tragic Sentiment of Life in Men and In Societies 1912). It is the distinguishing mark of major thinkers to create categories of thought and concepts which remain uniquely theirs. Sartre's engagé, Eliot's wasteland, Nietzsche's death of God or Kierkegaard's fear and trembling Del sentimiento trágico de la vida stands out.
