The Pontifical University of Saint Thomas Aquinas (PUST), also known as the Angelicum in honor of its patron the Doctor Angelicus Thomas Aquinas, is located in the historic center of Rome, Italy.

The Angelicum is administered by the Catholic Order of Preachers, also known as the Dominican Order, and is a central locus of traditional Dominican Thomist theology and philosophy.

The Posterior Analytics is a text from Aristotle's Organon that deals with demonstration, definition, and scientific knowledge. The demonstration is distinguished as a syllogism productive of scientific knowledge, while the definition marked as the statement of a thing's nature, ... a statement of the meaning of the name, or of an equivalent nominal formula.
The Physics is a named text, written in ancient Greek, collated from a collection of surviving manuscripts known as the Corpus Aristotelicum, attributed to the 4th-century BC philosopher, teacher, and mentor of Macedonian rulers, Aristotle. Due to the unique educational methods of the Athenian school founded by Aristotle, the Lyceum, at the period of its greatest success, and the accidental circumstances surrounding the disposition and rediscovery of its library after his death, it is possible to say that without a doubt some of that library descends to the Corpus and that some must be attributed mainly or entirely to Aristotle, but it is not possible to say for sure which works. The two answers excluded by the circumstances are "all" and "none".

Peter John Olivi, also Pierre de Jean Olivi or Petrus Joannis Olivi, was a Franciscan theologian who, although he died professing the faith of the Roman Catholic Church, became a controversial figure in the arguments surrounding poverty at the beginning of the 14th century.

His support of the extreme view of ecclesiastical poverty played a part in the ideology of the groups coming to be known as the Spiritual Franciscans or Fraticelli.
