8 Occurrents

The category of occurrents centers around the more intuitive notion of processes. It captures processes themselves and several other categories that can be derived from processes and share the feature of being extended in time (in various ways). Accordingly, processes have special connections to time entities, i.e., to chronoids and their boundaries. Some examples of occurrents include: a rhinitis, seen as a sequence of different states of inflammation; writing a letter; sitting in front of a computer viewed as a state extended in time; a clinical trial; the treatment of a patient; the development of a cancer; a lecture in the sense of an actual event as well as a series of actual events, but opposed to the abstract notion of lecture; an examination.
