The term intentionality was introduced by Jeremy Bentham as a principle of utility in his doctrine of consciousness for the purpose of distinguishing acts that are intentional and acts that are not. The term was later used by Edmund Husserl in his doctrine that consciousness is always intentional, a concept that he undertook in connection with theses set forth by Franz Brentano regarding the ontological and psychological status of objects of thought. It has been defined as "aboutness", and according to the Oxford English Dictionary it is "the distinguishing property of mental phenomena of being necessarily directed upon an object, whether real or imaginary". It is in this sense and the usage of Husserl that the term is primarily used in contemporary philosophy. The concept of intentionality has its foundation in scholastic philosophy with the earliest theory being associated with St. Anselm's ontological argument for the existence of God and his tenets distinguishing between objects that exist in the understanding and objects that exist in reality.
