13. What more is there to say about worlds of atonements that you don't already know, since you have only to look at the one in which you live? The great number of superior intelligences amongst your inhabitants indicates that the Earth is not a primitive world, destined to receive beings who have recently left the hand of the Creator. The innate qualities which they bring with them constitute a proof of their having already lived and achieved a certain degree of progress. But the number of vices to which they are subject also shows their great moral imperfections. This is why God has placed them in an ungrateful world, in which they can make atonement through heavy work and the suffering of the miseries of life, until they deserve to ascend to happier planets.
