Letters 65.15

Either give your opinion, or, as is easier in cases of this kind, declare that the matter is not clear and call for another hearing. But you will reply: “What pleasure do you get from wasting your time on these problems, which relieve you of none of your emotions, rout none of your desires?” So far as I am concerned, I treat and discuss them as matters which contribute greatly toward calming the spirit, and I search myself first, and then the world about me.
