Thus Spoke Zarathustra by Friedrich Nietzsche (Paperback)

Nietzsche's most famous work, told as the journey of a prophet who comes down from the mountain. The Übermensch, eternal recurrence and the call to create your own values, delivered as part poem, part sermon.

Read it if: you want the source of ideas you've seen quoted everywhere, in their original fire.

Third Shelf — a heavyweight. Save it for when your attention is back in shape.
