Antonio Millán-Puelles (February 11, 1921 – March 22, 2005) was a Spanish philosopher interested in phenomenology and metaphysics, who published many books and articles. He discovered his vocation to philosophy when he read Husserl’s Logical Investigations and abandoned the medical studies he had just begun.He combined a complete clarity and precision with depth and profound insights. His preferred topics were the relationship between conscience and subjectivity, the value of freedom, the ideal and the unreal being, and the rapport between metaphysics and logic. "The properly and refreshing philosophical attitude of the author is precisely made evident by the fact that he is open to the truth regardless of who stayed it. He is close to the phenomena and data of experience and analyzes them carefully and without a trace of reductionism and constructivism".
