Quote from : Matthew Arnold: The Complete Poems Book

But often, in the world’s most crowded streets, But often, in the din of strife, There rises an unspeakable desire After the knowledge of our buried life; A thirst to spend our fire and restless force In tracking out our true, original course; A longing to inquire Into the mystery of this heart which beats So wild, so deep in us—to know Whence our lives come and where they go.
