There was a negative theology, but there was also a positive theology. We are out and in at the same time. It is a matter of each of us. That is why the Fall is not final. It is not like a ladder.

To Maimonides, the code of behavior is an introduction to the Pardes. He starts with the Pardes, only then to go on to talk about the Law. The Pardes is integral to the Mishne Torah. Each of us then is his own Messiah, and we don't need another Messiah - as individuals. As a collective, it is another story.
