Ooo philosophy. I love it. Romantics put so much weight on emotion because emotion and its rose tinted glasses tend to simplify situations and put them in views similar to the art in society. Furthermore, as the saying goes, art imitates life, and this is something romantics take with them everywhere in justifying their mindset, which actually hinders their perception on emotion, keeping its thumbs in the scale between emotion and rationality, though reason is entirely subjective. What emotion can give that rationality does not is mood, which helps construct the context of everything we read and interact with. It is what keeps my conversations from being remembered as what information i provided and what I learned and coats those memories in how I feel about the person. After all, most of our judgement and perception of the people and circumstances surrounding us is built on a foundation of emotion, much like babies in the sensorimotor stage of cognition theorized by Jean Piaget. I hope this helped.
