text: You cannot conceive what distinct progress I notice that each day brings to me. And when you say: "Give me also a share in these gifts which you have found so helpful," I reply that I am anxious to heap all these privileges upon you, and that I am glad to learn in order that I may teach. Nothing will ever please me, no matter how excellent or beneficial, if I must retain the knowledge of it to myself. And if wisdom were given me under the express condition that it must be kept hidden and not uttered, I should refuse it. No good thing is pleasant to possess, without friends to share it.
