Rabbi Yehudah said, etc.: Rabbi Yitzchak, this is certainly so, and He created man above all, because he includes and completes all the details of creation, and this is what is said: "I made the earth and the man upon it I created", "I made the earth", this is certain and does not need to be said. But He tells us, what is the reason I made the earth? Because I created man upon it, because he is the sustainer of the world, and that everything should be a single perfection. In other words, that the purpose of the entire world and its perfection is man.
