Haecceity

Haecceity ( neulat. to Latin haec, " this" ) or this -ness or this-ness refers to a philosophical conception of art that was in scholasticism, starting from John Duns Scotus, in particular from the following it, widespread mindset of Scotists developed. The haecceity refers to the specific of a single object, as opposed to Quidditas, the general properties of an object class. The term belongs to the realm of individuation, ie the separation of the General in One. The original late scholastic name should thus be settled ontology or metaphysics in the context of the philosophical disciplines and in particular to the universals as well as issues of general logic.

In the scholasticism the individual was first of Thomas Aquinas with Aristotle viewed as a special case of the general. The individual himself is not scientifically debatable ( individual est ineffabile ). The core of the doctrine of haecceity is now based on the idea that an individual's existence is not a defect but a perfection. It is a unique and special. On the individual can be seen as something unique point only showing: a "This -Da ". The introduction and use of the term haecceity, which until then secondary classified individuality gets a larger weight. The single thing as a positive being is now conceptually recognizable accorded a higher rank. In addition, the individual, the particular over the general, that which is perfect is. The individual has an independent reality, is a further non- derivable fact.
