" I have for many years endeavored to make this vital truth clear; and still people marvel when I tell them that I am happy. They imagine that my limitations weigh heavily upon my spirit, and chain me to the rock of despair. Yet, it seems to me, happiness has very little to do with the senses. If we make up our minds that this is a drab and purposeless universe, it will be that, and nothing else. On the other hand, if we believe that the earth is ours, and that the sun and moon hang in the sky for our delight, there will be joy upon the hills and gladness in the fields because the Artist in our souls glorifies creation. Surely, it gives dignity to life to believe that we are born into this world for noble ends, and that we have a higher destiny than can be accomplished within the narrow limits of this physical life.
