When grown people speak of the innocence of children, they don’t really know what they mean. Pressed, they will go a step further and say, Well, ignorance then. The child is neither. There is no crime which a boy of eleven had not envisaged long ago. His only innocence is, he may not be old enough to desire the fruits of it, which is not innocence but appetite; his ignorance is, he does not know how to commit it, which is not ignorance but size.
