DUELING DUALITIES PT. 2

 Now that I've specified in Part 1 my reasons for taking exception to Jung's characterization of what he termed "perception" and "judging" functions, I want to throw out a speculation as to why that particular duality might have been important to Jung, beyond the reasons cited in his 1912 PSYCHOLOGICAL TYPES-- a speculation pertaining to what I've termed "the two forms of knowledge." In William James' THE PROBLEMS OF PSYCHOLOGY, James stated:                                                                                                                            "There are two kinds of knowledge broadly and practically distinguishable: we may call them respectively knowledge of acquaintance and knowledge-about."                                              

I went into detail as to the history preceding and following this conception in my essay WHITE NOISE, so I won't duplicate that explanation here. What I find interesting, though, is how much the input from what Jung calls the "perceiving functions" resemble the idea of "knowledge by acquaintance," while the "judging functions" resemble the idea of "knowledge-about" (which Bertrand Russell gave the superior term of "knowledge by description.")                         

 Now, I haven't reread PSYCHOLOGICAL TYPES in many years, nor, prior to writing this essay, did I even go over the notes I made from my first reading. I doubt that Jung said anything, directly or indirectly, about the parallel I'm suggesting, for the very good reason that TYPES doesn't concern the nature of knowledge. Jung wrote that book to give his detailed analysis of the two types of people he termed "introverts" and "extroverts," and how such psychological types manifest in reaction to the four functions coded in the overall makeup of human beings. It's one of Jung's great books, but inevitably it was influenced by the intellectual currents surrounding it-- which included James, Jung's senior by thirty years, and whom Jung visited twice just before James' passing in 1910. Jung admired James' 1902 VARITIES OF RELIGIOUS EXPERIENCE. and the psychologist devotes twenty pages of TYPES comparing his concept of two types of people to James' two types of philosophers. So, though I didn't reread TYPES, I did check to see everything Jung wrote about James in that particular book.                                           

 Now, one interesting datum is that though Jung claims to have "limited" knowledge of James' corpus of writings, and almost everything Jung cites in his tome about James' "two types" comes from James' 1907 book PRAGMATISM, Jung has one citation from the 1890 PRINCIPLES OF PSYCHOLOGY-- which, as noted above, is the book from which the "two forms of knowledge" is put forth. I don't know that Jung never commented on the two forms elsewhere in his works, but IMO he was too good a scholar to quote from a book he cited in an appendix. And for that matter, had he never encountered James' 1890 formulation and had never been influenced by James in his "perceiving/judging" categories, Jung also could have got something not dissimilar from Schopenhauer's dichotomy of "percepts and concepts." But James is still the best bet for influence-- and even though Jung didn't agree with everything James wrote, he paid the older man an exceeding compliment by being influenced by him-- just as I've sought to compliment Jung in my own small way.
