Now it seems to me that love of some kind is the only possible explanation of the extraordinary amount of suffering that there is in the world. I cannot conceive of any other explanation. I am convinced that there is no other, and that if the world has indeed, as I have said, been built of sorrow, it has been built by the hands of love, because in no other way could the soul of man, for whom the world was made, reach the full stature of its perfection. Pleasure for the beautiful body, but pain for the beautiful soul.
