where every conscious act is directed by the tendency to follow introversion for introverts and extraversion for extraverts. Jung's definition of the general attitude was not limiting the individual from experiencing the opposing attitude, but offers the "decisive determination". The primary, or most developed, differentiated, and conscious function, is entirely positioned in the service of the conscious attitude of introversion or extraversion, but even if all other functions can be conscious and made to follow the general attitude, they are of less differentiation and are hence strongly affected by the opposing attitude of the unconscious. Later in the book, Jung describes the auxiliary function as being capable of some significant development or differentiation, if it remains less differentiated of that of the primary. His views on the primary and auxiliary functions both being of enough differentiation to be considered conscious and set aside with the primary as opposed to the most inferior two functions can be noted as early as Psychological Types. The four basic psychological functions, thinking, feeling, sensation, and intuition are "basic functions" that can be briefly defined as follows. Thinking According to Jung, thinking is "that psychological function which, in accordance with its own laws, brings given presentations into conceptual connection." Jung said that the thinking function should be delegated solely to 'active thinking' in contrast to 'passive thinking'. According to him, active thinking uses concepts to connect information, being considered judgement as a result. He writes that passive thinking "lacks any sense of direction", since it is not in accordance with an aim. He refers to it as 'intuitive thinking' instead. Later, some interpreted Jung's extraverted thinking and introverted thinking to mean other than the function of thought as represented in extraverts and introverts respectively. In Adler and Hull's translation of Jung's Psychological Types, Jung states: "Apart from the qualities I have mentioned, the undeveloped functions possess the further peculiarity that, when the conscious attitude is introverted, they are extraverted and vice versa. One could therefore expect to find extraverted feelings in an introverted intellectual..." Extraverted thinking Extraverted thinking is the thinking function that is objective (being extraverted). Extraverted thinking often places information such as facts in high order; it is a process that is concerned with organisation and hierarchy of phenomena. "In accordance with his definition, we must picture a, man whose constant aim -- in so far, of course, as he is a [p.
