And all the books you've read have been read by other people. And all the songs you've loved have been heard by other people. And that girl that's pretty to you is pretty to other people. and that if you looked at these facts when you were happy, you would feel great because you are describing 'unity.

The speaker reframes a set of seemingly deflating observations—your favorite books, songs, and attractions are shared by countless others—as a consoling insight: individuality is not erased by common experience but connected to it. Read in this light, “unity” names the comfort of belonging to a wider human community of readers, listeners, and lovers. The quote suggests that mood determines meaning: when unhappy, shared tastes can feel like proof of insignificance; when happy, the same facts become evidence of participation in something larger than the self. It is an argument for solidarity through culture and desire, and for choosing an interpretive stance that turns sameness into connection.
