I assess the power of a will by how much resistance, pain, torture it endures and knows how to turn to its advantage.

To blaspheme the earth is now the most dreadful sin, and to rate the heart of the unknowable higher than the meaning of the earth!

You who hate the Jews so, why did you adopt their religion?
