What does the part that I've put in bold mean? Is it saying that with Fi demonstrative, your feelings towards a person depend on the situation? And are always changing?as a demonstrative (8th) function (SEI and IEI)
The individual is quite adept at understanding the interactions in personal bonds between two individuals, even in the absence of an obvious external emotional expression; but he is inclined to regard them as of lesser importance, and less interesting, than the broader emotional interactions in the context of a larger group. Moreover, those personal bonds are perceived as situational and dynamic rather than static.
Whereas with Fi base, your feelings towards a person are constant and independent of any external factors?
(just trying to clarify)
