He stands for the moral law. I Innocence is overlaid by years of less than stellar performance. Ideals become obscure, one learns to prefer waffling to a Laurentian grill, nostalgia for a better time sets in. But there is no actual sin to mar the record of the newborn babe or child.

Somewhere beneath consciousness is a mechanism that makes us do the things we do. Philosophers speak of parts of the soul, which in turn is part of what we are, form to body. Our mental powers include mind and will and imagination. There are mindless desires too, seemingly with a mind of their own, another law in our members. The moral drama consists of bringing these into alignment, becoming mindful, thought directing our desires and not being led around by them, in Plato's phrase.
