OusiaOusia (ˈuːziə,_ˈuːsiə,_ˈuːʒə,_ˈuːʃə; οὐσία) is a philosophical and theological term, originally used in ancient Greek philosophy, then later in Christian theology. It was used by various ancient Greek philosophers, like Plato and Aristotle, as a primary designation for philosophical concepts of essence or substance. In contemporary philosophy, it is analogous to English concepts of being and ontic. In Christian theology, the concept of θεία ουσία (divine essence) is one of the most important doctrinal concepts, central to the development of trinitarian doctrine.
RoscellinusRoscelin of Compiègne (1050-1125), better known by his Latinized name Roscellinus Compendiensis or Rucelinus, was a French philosopher and theologian, often regarded as the founder of nominalism. Roscellinus was born in Compiègne, France. Little is known of his life, and knowledge of his doctrines is mainly derived from Anselm and Abelard. He studied at Soissons and Reims, was afterwards attached to the cathedral of Chartres and became canon of Compiègne. As a monk of Compiègne, he was teaching as early as 1087.
Event (philosophy)In philosophy, events are objects in time or instantiations of properties in objects. On some views, only changes in the form of acquiring or losing a property can constitute events, like the lawn's becoming dry. According to others, there are also events that involve nothing but the retaining of a property, e.g. the lawn's staying wet. Events are usually defined as particulars that, unlike universals, cannot repeat at different times. Processes are complex events constituted by a sequence of events.
Scotistic realismScotistic realism (also Scotist realism or Scotist formalism) is the Scotist position on the problem of universals. It is a form of moderate realism, which is sometimes referred to as 'scholastic realism'. The position maintains that universals exist both in particular objects and as concepts in the mind. The "problem of universals" was an ancient problem in metaphysics about whether universals exist. For John Duns Scotus, a Franciscan philosopher, theologian and Catholic priest, universals such as "greenness" and "goodness" exist in reality.
