There is also, however -- and now I come to the question of the introverted intellect -- an entirely different kind of thinking, to which the term I "thinking" can hardly be denied: it is a kind that is neither orientated by the immediate objective experience nor is it concerned with general and objectively derived ideas. I reach this other kind of thinking in the following way. When my thoughts are engaged with a concrete object or general idea in such a way that the course of my thinking eventually leads me back again to my object, this intellectual process is not the only psychic proceeding taking place in me at the moment. I will disregard all those possible sensations and feelings which become noticeable as a more or less disturbing accompaniment to my train of thought, merely emphasizing the fact that this very thinking process which proceeds from objective data and strives again towards the object stands also in a constant relation to the subject. This relation is a condition sine qua non, without which no think- [p. 431] ing process whatsoever could take place. Even though my thinking process is directed, as far as possible, towards objective data, nevertheless it is my subjective process, and it can neither escape the subjective admixture nor yet dispense with it. Although I try my utmost to give a completely objective direction to my train of thought, even then I cannot exclude the parallel subjective process with its all-embracing participation, without extinguishing the very spark of life from my thought. This parallel subjective process has a natural tendency, only relatively avoidable, to subjectify objective facts, i.e. to assimilate them to the subject.
