[Buds of May]

Enigmatically, the Introverted Judgment tends to be utilized for external purpose by the ENTP, as the type in itself is most properly classified as Extroverted.

Yes, enigmatically.
What I'm trying to get a sense of is how Ti primarily plays a supporting role to Ne. Primarily as in overall, not as a director toward its own end, not necessarily leading back to itself. It reads like: Judge in order to Perceive. Thought in the service of Observation. Which seems, well, counterintuitive. But you propose the Ne with its own agenda. Which is ... informed by judgment but not judgment's agenda? ... unconsciously motivated?

Examples help in the sense of being worth a thousand words. "As Extroverts, ENTPs are doers, therefore they see imagination and logic as means to the end of achieving an external goal." External goal -- is this like a Te function thing? "Extroverted Intuition alone allows for the ENTP to assess the general ambience of the situation and present whatever façade is necessary to achieve a goal, yet the Extroverted Feeling promotes such an endeavor by establishing a clear-cut external agenda." Fe? Examples can wrap around functional nuances that are complex to describe through analysis.

Unlike the INTs, the ENTP does not need to retreat into himself to process or analyze ideas, as he simply can volley them as he goes.

What might be an ENTP's perception of his own Ti?

However, ENTPs who have developed their introverted judgment and have come in tune with the higher purpose will liberate themselves from the tyranny of the external agenda and only then will be able to come to terms with their inner being and view themselves as true individuals as opposed to mere agents of the network they are environed in. There they will be able to see a sharp distinction between the things they do to humor their outer environment and what is a true a manifestation of their inner being.

How might an ENTP conceive of "inner being"? How is having this Ti experience different for him than just having an INTP experience?

“It goes without saying that such a type is uncommonly important both economically and culturally. If his intentions are good, i.e, if his attitude is not too egocentric, he can render exceptional service as the initiator or promoter of new enterprises. He is the natural champion of all minorities with a future. Because he is able, when oriented more to people than things, to make an intuitive diagnosis of their abilities and potentialities, he can also “make” men. His capacity to inspire courage or to kindle enthusiasm for anything new is unrivalled..”

Where are you getting these quotes? Can you go into detail on the capability mentioned above?
