the work introduces Unamuno's exploration of the human condition, emphasizing the significance of the individual and the dilemma of existence involving mortality and desire for immortality. He critiques abstract philosophical concepts that disregard the inherent suffering and emotions tied to real life. The author illustrates how various philosophers, while pursuing theoretical knowledge, overlook the vital emotional and existential challenges that define the human experience. Unamuno argues that this "tragic feeling of life" is a universal sentiment that should guide our understanding of philosophy and existence, creating a tension between the individual's rational thoughts and primal emotional needs.
