Children are by nature, by necessity, irresponsible, and irresponsibility in them, as in puppies or kittens, is part of their charm. Carried into adulthood it becomes a dire practical and ethical failing. Uncontrolled spontaneity wastes itself. Ignorance isn’t wisdom. Innocence is wisdom only of the spirit. We can and do all learn from children, all through our life; but “become as little children” is a spiritual counsel, not an intellectual, practical, or ethical one.
