He is considered to be one of the major figures of medieval thought and was at the centre of the major intellectual and political controversies of the 14th century.

Scholasticism was a medieval school of philosophy that employed a critical organic method of philosophical analysis predicated upon the Aristotelian 10 Categories. Christian scholasticism emerged within the monastic schools that translated scholastic Judeo-Islamic philosophies, and thereby "rediscovered" the collected works of Aristotle. Endeavoring to harmonize his metaphysics and its account of a prime mover with the Latin Catholic dogmatic trinitarian theology, these monastic schools became the basis of the earliest European medieval universities, contributing to the development of modern science; scholasticism dominated education in Europe from about 1100 to 1700. The rise of scholasticism was closely associated with these schools that flourished in Italy, France, Portugal, Spain and England.

Peter John Olivi, also Pierre de Jean Olivi or Petrus Joannis Olivi, was a French Franciscan theologian and philosopher who, although he died professing the faith of the Roman Catholic Church, remained a controversial figure in the arguments surrounding poverty at the beginning of the 14th century. In large part, this was due to his view that the Franciscan vow of poverty also entailed usus pauper. While contemporary Franciscans generally agreed that usus pauper was important to the Franciscan way of life, they disagreed that it was part of their vow of poverty. His support of the rigorous view of ecclesiastical poverty played a part in the ideology of the groups coming to be known as the Spiritual Franciscans or Fraticelli.

The principle of individuation is a criterion that individuates or numerically distinguishes the members of the kind for which it is given, that is by which we can supposedly determine, regarding any kind of thing, when we have more than one of them or not. It is also known as a 'criterion of identity' or 'indiscernibility principle'. The history of the consideration of such a principle begins with Aristotle. It was much discussed by the medieval philosopher Duns Scotus with his "haecceity" and later, during Renaissance, by Francisco Suárez (1548–1617), Bonaventure Baron (1610–1696) and Leibniz (1646–1716).
