It seemed to Jack that if an ordinary human being, his own son, no one particular, could have this purity of mind, then perhaps the isolated deeds of virtue at which people marveled in later life were not really isolated at all; perhaps they were the natural continuation of the innocent goodness that all people brought into the world at their birth. If this was true, then his fellow-human beings were not the rough, flawed creatures that most of them supposed. Their failings were not innate, but were the result of where they had gone wrong or been coarsened by their experiences; in their hearts they remained perfectible.
