Two qualities Pope Benedict XVI is known for are his intellect and his writing talents. He has been quite prolific. The Ratzinger Fan Club has a listing of many of his writings that can be accessed online.
Here is a listing of some of my favorites:
*** "Europe's Crisis of Culture," given at Subiaco the day before Pope John Paul the Great passed away and a talk where Ratzinger stressed the need for another Benedict (hmmm) ***
*** Funeral Homily for Msgr. Luigi Giussani, where Ratzinger received enthusiastic applause after the homily ***
*** "The Theology of Kneeling" from The Spirit of the Liturgy. ***
"Interreligious Dialogue and Jewish-Christian Relations"in Many Religions, One Covenant.
The Question of Suffering, the Response of the Cross, from God and the World: A Conversation with Peter Seewald.

*** Truth and Freedom *** Highly recommended.
