Consider a pair of hypotheses: first, that one major strand of Jewish mysticism supports both the study and the practice of computer science, which I take to include both the formal mathematical and scientific study of the informational and the engineering of informational systems. Second, that our current technical understanding of computation helps clarify a key aspect of the Jewish mystical tradition. Begin with a digression on the role of computer science in showing scientifically that the world itself is more than just material, turn to an examination of one aspect of the Kabbalah, and then look at the practice of computer science as a modern realization of this aspect of the Kabbalah.
