Quiddity


In scholastic philosophy, "quiddity" was another term for the essence of an object, literally its "whatness" or "what it is".

Etymology

The term "quiddity" derives from the Latin word quidditas, which was used by the medieval scholastics as a literal translation of the equivalent term in Aristotle's Greek to ti en einai or "the what it was to be ".

Overview

Quiddity describes properties that a particular substance shares with others of its kind. The question "what is it?" asks for a general description by way of commonality. This is quiddity or "whatness". Quiddity was often contrasted by the scholastic philosophers with the haecceity or "thisness" of an item, which was supposed to be a positive characteristic of an individual that caused them to be this individual, and no other. It is used in this sense in British poet George Herbert's poem, "Quiddity".
