 Luis Villoro was a diligent student of the most important philosophical currents of the second half of the 20th century: existentialism, phenomenology, Marxism, analytic philosophy, and multiculturalism. However, in his reflections one can observe a common thread of lasting questions concerning the metaphysical understanding of alterity, the limits and boundaries of reason, the relationship between knowledge and power, community, an ethical reflection of injustice, a defense of and respect for cultural diversity, and a critical examination of the role of philosophy. Some of his books are: Los grandes momentos del indigenismo en México (1950), Creer, saber, conocer (1982), El concepto de ideología (1985), and El poder y el valor (1997).
