One hundred years ago, in 1913, Miguel de Unamuno published a book called The Tragic Sense of Life. It was considered - in his time - to be a masterpiece, an influential work of early existentialist philosophy. But The Tragic Sense of Life is more (or you might say less) than a work of philosophy. It is a deeply personal account of one man's anguish in the night. (TheSmartSet.com) Miguel de Unamuno is to-day the greatest literary figure of Spain. Baroja may surpass him in variety of external experience, Azorín in delicate art, Ortega y Gasset in philosophical subtlety, Ayala in intellectual elegance, Valle Inclán in rhythmical grace. Even in vitality he may have to yield the first place to that over-whelming athlete of literature, Blasco Ibáñez. But Unamuno is head and shoulders above them all in the highness of his purpose and in the earnestness and loyalty with which, Quixote-like, he has served all through his life his unattainable Dulcinea.
