My point is that logic may or may not be Ti's guiding star. "Logic" is an Occidental intellectual bias. Ti will still exist in cultures where logic is not put on a pedestal. That internal basis may for example be meditation as a way of finding truth. The quest for intellectual truth is
internally determined, that's all that matters here! All else is stereotyping.
My point is that Robin Williams poured his self into his roles. His values, his emotions, his sense of every feeling in the rainbow. He poured that into his characters. I do not doubt for a second that an ENTP could be an excellent actor or comedian
...or that an ENTP can't pour him or herself into a character...
- certainly there are many - but the way Robin Williams poured his self into his characters is so Fi. He claimed the voice of the Genie as his own intellectual property - him claiming his self-expression and creativity as his own. His humor had a cringing, self-aware element that is so Fi. He was self-referential. Obama said this - "He arrived in our lives as an alien – but he ended up touching every element of the human spirit." Human spirit and universal connection. That is NeFi at its purest.
Robin Williams was also a cultural critic, a skeptical Ti. For example, 'Some people say Jesus wasn't Jewish. Of course he was Jewish! Thirty years old, single, lives with his parents, come on. He works in his father's business, his mom thought he was God's gift, he's Jewish. Give it up." Never mind, ENFPs can be that way too!
I remember Robin Williams well. His behavior per se doesn't matter, it's the hyper-intensity of the behavior. He was busting out with extroversion, in the right settings, completely unregulated out-of-control stream-of-thought extroversion strewn here and there with "why?" moments.
He was always asking "why?" He was an NT who wanted to know the reasons. He didn't ask his audience, he asked nobody in particular and everybody in general, or perhaps he was just talking out loud, expressing something of his internal world in between the bouts of intense stream-of-thought.
