 Adolfo Sánchez Vázquez was very young when he arrived in Mexico and he began his philosophical studies in Mexico. He produced a solid body of work dealing with the concepts of Marxist ethics and aesthetics. One contribution to Marxist philosophy was his critical reflection on the concept of praxis, and he was critical of the aesthetic doctrine of Socialist realism. Among his main books we can mention: Las ideas estéticas de Marx (1965), Una filosofía de la praxis (1967), and Ética (1969). Many Mexican Marxist philosophers of subsequent generations studied under him, and there was an important debate between Sánchez Vazquez and Villoro concerning the concept of ideology.
