 The last twelve years of Vives’ life were his most productive, and it was in this period that he published several of the works for which he is best known today. These include De concordia et discordia in humano genere (On Concord and Discord in Humankind, 1529), a piece of social criticism emphasizing the value of peace and the absurdity of war; De disciplinis (On the Disciplines, 1531), an encyclopedic treatise providing an extensive critique of the foundations of contemporary education, as well as a program for its renewal; and De anima et vita (On the Soul and Life, 1538), a study of the soul and its interaction with the body, which also contains a penetrating analysis of the emotions. De veritate fidei Christianae (On the Truth of the Christian Faith), the most thorough discussion of his religious views, was published posthumously in 1543. He died in Bruges on May 6, 1540.
