In 1920, the Dominican monk Sertillanges wrote "The Intellectual Life: Its Spirit, Conditions, Methods," a masterpiece that proposed to address the Sixteen Precepts of Saint Thomas, but which gained practical substance for preparation during and after study. "The Intellectual Life" goes beyond observations for studies. They are completely perennial and fundamental methods for the development of humans as intelligent beings. Praised by intellectuals, critics, and specialized journalists, the enduring success of "The Intellectual Life" is the greatest proof of its value.
