 Joaquín Xirau wrote several books on metaphysics, the history of philosophy, and the philosophy of education. After arriving in Mexico, he wrote Amor y mundo (1940), a reflection on love understood as Eros and caritas. His ontology is dialectical, and he claims that being and value, as well as subject and object, are merely abstract ideas if they are considered static realities outside change. His premature death at the age of 50 prevented him from being more influential than he should have been.
