Kant's viewpoints are Ti and anti-Fi, in that prinicples should be consistent and universal. If you decide something is the right thing to do, you should also be able to see it as the right thing for anyone else to do in the same circumstances. An objective viewpoint. This is against the subjectivity of Fi where the who is just as important as the what, and the sentiments towards and background of that who is taken into account. This is why Fi and favoritism can be so linked together. The difference between Ti and Fi is objective vs subjective (aka external/internal, universal/personal, explicit/implicit) To Fi, Ti can look cold, or heartless, and to Ti, Fi can look biased and hypocritical but it all comes down to objective vs subjective.
Example: Two people commit the same crime, objectively both should be given the same punishment. Subjectively a person might take into account factors other than the crime, their feelings about the person, etc. and give different punishments.
Each person will have a different standard, or different set of principles, whether Ti or Fi. In other words, a Ti person could live by their own set of laws, completely at odds with the rest of the world quite easily (and that'd be an example of ignoring Te in favor of Ti,) but would apply those laws universally, iow holding each person to the same standards and treatment regarding the Ti's own principles.
As for Te vs. Ti, that's externally oriented vs internally oriented thinking. I hate how the definitions of the elements and the words we have to work with make it seem like there's overlap between different concepts when there isn't. Too many of the same words for different ideas. We need a better vocabulary to make discussion easier and distinctions more clear. But anyway, all introverted elements are field, all extroverted ones are object. And so all extroverted elements are looking at the real, objects, what's there, real-world stuff, and the introverted elements are looking at how things fit together/relate to each other. So with Ti vs Te: Ti has this mental construct that explains reality in some way and puts it together, while Te is directly involved in that reality.
In a way, you can say that Te is externally objective, while Ti is internally objective. Makes sense to me, but whether it does to anyone else is another question, lol. Like I already said, we need better, more distinctive vocabulary because I can already see people arguing with the semantics of that statement.Originally Posted by Jung
