Quiddity
From Wikipedia, the free encyclopedia
In philosophy, quiddity is identity or "whatness," i.e., something's "what it is." The term derives from the Latin word "quidditas," which was used by the medieval Scholastics to refer to a concept of substance they encountered while translating the works of Aristotle.
The (Greek equivalent) term was used by Aristotle in reference to an entity's aspects of "matter" and "form."
It describes properties a particular substance (e.g. a person) shares with others of its kind. The question "what (quid) is it?" asks for a general description by way of commonailty. This is quiddity or "whatness" (i.e., its "what it is"). Quiddity is often contrasted with the haecceity or "thisness" of an item, which, in turn, describes the particular properties of an object or substance (e.g. a particular person).
[edit] Other senses
- In law, the term is used to refer to a quibble or academic point. An example can be seen in Hamlet's graveside speech found in Hamlet by William Shakespeare. "Where be his quiddities now, his quillets, his cases, his tenures" says Hamlet referring to a lawyer's quiddities.
- Quiddity is the name for the mystical dream sea in Clive Barker's novel The Great and Secret Show that exists as a higher plane of human existence. It is featured as more of a literal sea in the novel's sequel, Everville and the related short story, On Amen's Shore.
