Although I have read a little bit about the role of the shadow functions, this reading has been limited to only insignificantly small blurbs on the internet, as I have actually not yet had the opportunity to get my hands on any professional literature dealing with this subject (such as Lenore Thomson's book).
For those who have had the opportunity to research this, what precisely are the theorized functions of a type's shadow functions? Take INTP for example. What is the specific role that the 5th (Te), 6th (Ni), 7th (Se), and 8th (Fi) functions?
Feel free to explain in great detail.
