" In heaven, everything is good; in hell, everything bad. In the world, since it lies between the two, you find both. We are placed between two extremes, and so participate in both. Good and bad luck alternate; not all is happy, nor all hostile. This world is a zero: on its own, it's worth nothing; joined to heaven, a great deal. Indifference to its variety constitutes good sense - the wise are never surprised. Our life is arranged like a play, everything will be sorted out in the end. Take care, then, to end it well. "
