In every work of genius we recognize our own rejected thoughts; they come back to us with a certain alienated majesty
This assertion of Emerson's must be accurate; else, how would the poet write such emotive langugage to which readers respond? If there is no emotional connection--if readers and listeners had not first thought about their own emotions in some other context--the poet's language could not touch the readers so.
Truly, as readers, people bring to a text much of what they themselves have already experienced and thought. However, few record their thoughts or even can formulate them into something worthwhile. Thus, the genius of these thoughts are cast aside until such time that they view them in a work of art created by another.
