 This distinction drawn by Ortega between his vitalistic perspective and Cohen’s all-embracing logic suggests that Ortega’s experience at Marburg brought him closer to a critical Neo-Kantianism than to an absolute Neo-Kantianism. The critical approach to philosophical issues became an important factor in influencing Ortega’s thought and in the philosophical training that he received. In his “Reflections on Kant’s Centenary” in 1929, Ortega, in retrospect, referred metaphorically to his struggle with Kant and Neo-Kantian philosophy as having occurred in a “Kantian prison”, (Obras, IV: 25) ; and in his “Prologue for Germans”, he acknowledged his experience at the University of Marburg to have been an important factor in influencing his intellectual development. “In this city”, he reflected, “I passed the equinox of my youth; to it I owe half, at least, of my hopes and almost all my discipline” (Obras, II: 558–59, VIII: 20–21).
