Reddit reviews From Image to Likeness: A Jungian Path in the Gospel Journey

Here's a quick rundown:

• He considered introversion/extroversion to be the biggest difference above everything else.
  
  
• He described 8 types of personality, but also said that most normal people would not really fit either type and could only be classified on introversion/extroversion.
  
  He ordered functions like this:
  
  
• First the dominant one in the person's I/E direction.
  
  
• He noted that most people also have a secondary function. He didn't mention the direction of it but we can conclude that it's direction would be the same as the dominant one.
  
  
• In every type description he briefly described a suppressed function that is opposed to the dominant one in every way (For introverted intuitives this was a primitive extroverted sensing)
  
  
• A third function isn't mentioned anywhere, instead he noted unconscious suppressed functions that balance out the dominant one.
  
  We can conclude from this that he viewed personality as if it was in an equilibrum, with people falling to their underdeveloped side when in stress. Since he put so much weight on I/E and didn't mention the direction of functions except the dominant and it's opposite, I believe we can conclude that in is model the second function wasn't opposite to the primary one.
  
  By the way, there are tons of other things that are opposites in MBTI, Jung's theories, modern psychology, and theories of other random people. For example the IEIE or EIEI function stack comes from this book written by a random person in 1983, but somehow has been adopted as THE canon model of personality in "jungian" MBTI circles.
