Introduction:

The work by Lucas Prieto Sánchez La conservación del universo según santo Tomás de Aquino responds perfectly to what its title indicates, and constitutes an important and up-to-date contribution on this subject in the extensive bibliography on the Angelic doctor. It is an issue that has not always been given sufficient attention, as it has been hidden behind others, which has sometimes contributed to its disfigurement. The present study, some of whose contributions have already been published in the form of articles, allows us to enter into the depth of this subject. We present below the main contents of the book under review, which corresponds to the author’s doctoral thesis, supervised by Fr Bonino op, at the Angelicum.
