ABSTRACT
Wishing to demonstrate how consciousness functions differently for different individuals in everyday life, Jung formulated a theory of psychological types, a theory that enables us to distinguish between the plural components of consciousness. He observed that while some people might be more interested in the external world, others would be more energised by the internal world. These two opposing traits were termed by Jung as the extraverted and introverted attitudes of consciousness. Yet, in addition to these attitudes towards the world there are, according to Jung, separate functions of the conscious mind. In his system, there are four main functions of consciousness: thinking, feeling, sensation and intuition. Jung assumed that the functions were physiologically based and had a psychic 'element' which is partially controlled by the ego. No one can dispense with any of the four functions; they are inherent to ego-consciousness. However, the use of one particular function may become habitual and exclude the others.
