I remember Jung said he was Introverted Thinking, or I remember reading someone say that Jung said so, and I assume you've probably read either myself say so, or the person who I read it from say so, correct?
However, I know he is often seen as an INTJ, and "anti-Fe".
I personally do associate his personality with INTJ, yes. Probably INTJ-Te, as it is a more "strong" form, whereas some other INTJs can be more... eh, withdrawn?
However, he could really be INTP or ISTP for all I know... I'm not too good at this. I've noticed that Jung in one photo looked a bit like Nietzsche.
I personally really enjoy reading Nietzsche. The poetic and/or aphoristic nature of his writing is really cool, since I find long passages can be hard to digest, and there is usually more insight in a single Nietzsche aphorism than what I see in a whole page of other philosophers that I've looked at.
It's also nice that he's not simply re-iterating Plato. He is a very opinionated writer, but that's honestly a nice thing to say, even if I find his judgements to be a bit too harsh at times.
