So the assertion of "'thinking' should, in my view, be confined to the linking up of representations by means of a concept, where, in other words, an act of judgment prevails, whether such act be the product of one’s intentions or not." is just plain wrong.
Thinking is NOT categorized by intentions IMO... at all. Though Thinking is a judging function, it doesn't actually provide motivation. That is F's goal. Insofar as T is a judgement function, it tells what is, not what to do. Yada yada, you can't get an ought from an is.
Next time, just state your opinion and why you dissagree to begin with. There is no need for passive aggression or condescension.
Jung did not say that thinking provides motivation, or that judgement tells what to do. He is saying that thinking, directed by intention, is what he termed as active thinking.
Active Thinking:
[intention] directs [thinking] results in [judgement]
Passive Thinking:
undirected [thinking] results in [judgement]
Jung saying that the term 'thinking' should be confined to the linking up of representations by means of a concept—is like saying that the term 'exercise' should be confined to sustained physical activity, rather than any physical exertion. While any physical exertion is technically exercise, calling it that undermines the value of the term.
My opinion is that all of the cognitive functions are thinking functions, and that neurons perform thinking function.
