This raises a pair of interesting system questions. The first is whether or not Fi and Te are adequate stand-ins for one another. That is, if a person is paying close attention to their inner feeling, are they genuinely ignoring outer generalisation or is it automatically included as an unconscious part of the structure of their feeling assessment? According to Jung, it's the latter, and I guess this means you can usually talk to Fi people about universalisability of their decisions *if* you avoid implying that the feeling is misplaced. You can--possibly, maybe--join in with them on assessing non-moral consequences *if* you allow that the feeling is the feeling and it's going to be part of the landscape whether you like it or not.
The second interesting system question is about the compatibility of the two logics. In real people the Ti/Fe and Fi/Te logics seem always to end up in different places. But do they have to? Suppose there were two people, both perfectly conscious, both ideally and fully able to access and operate the two aspects of their different judgment systems. What differences would we see in their final decisions? Would we see any differences?
I think over time the systems may converge.
But I don't know.
