At best we are creatures of reason, and by using reason we can cure ourselves of emotional excess. Purged of both hope and fear, we find courage in the face of helplessness, insignificance and uncertainty.

Yom Kippur, the Day of Atonement, is the holy of holies of Jewish time. It is that rarest of phenomena, a Jewish festival without food.

But sometimes the sight of someone in one faith wrestling with that faith can empower you to wrestle with another faith.
