extravert, n.All

An Extravert (n.) in ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠pure form does not exist — such a man would be in the lunatic asylum; the types are only penchants, points for orientation.

An Extravert (n.) speaks ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠a thin, poor and profuse language — yet when finished has said what he set out to say, whereas an introvert's thought expanded into a book would still not be fully expressed.
