Romeo and Juliet, William Shakespeare
Dominant Fi: Romeo doesn’t care what his parents think of his decisions and acts purely based off of what he believes is right for himself. He doesn’t take on the same anger his family feels toward the Capulets and his only contribution to the feud is also based on personal disagreements (he kills Tybalt because he feels that Tybalt has wronged him, not because of his family’s disagreements). His choices don’t really involve logic, but are rather based purely on his feelings.
Auxiliary Ne: Romeo is easily satisfied, moving quickly from loving one girl to loving Juliet, and he falls in love with her rapidly. He likes to try and predict what other people will do, but isn’t always accurate in his guesses. He has a sense of idealism, seeing a big future with Juliet, but whenever his visions are crushed, he falls into fits of hopelessness. He is incredibly impulsive, and makes decisions quickly, often without thinking them through fully.
Tertiary Si: Romeo is extremely distraught about losing his past girlfriend and is only satisfied by a new one (Juliet). He thinks of her often while they are apart and uses his memory of her to help him cope. Romeo has an interest in history, and mentions it at times in talking to Juliet.
Inferior Te: As soon as Romeo decides what he wants, he goes after it rather impulsively. He decides within hours of meeting Juliet that he wants to marry her and acts to employ a friar to marry them. Likewise, he acts quickly to avenge Mercutio and comes up with a plan of escape for himself and Juliet.
