Book XXXIV: Sands at Seventy - To Get the Final Lilt of Songs

To get the final lilt of songs,
To penetrate the inmost lore of poets—to know the mighty ones,
Job, Homer, Eschylus, Dante, Shakespere, Tennyson, Emerson;
To diagnose the shifting-delicate tints of love and pride and doubt—
        to truly understand,
To encompass these, the last keen faculty and entrance-price,
Old age, and what it brings from all its past experiences.
