This sense of interior stability is consistent with one widely observable truth: the arc to any individual life is uniform over long periods of time. Subjects that draw us in will continue to draw us in. Patterns we respond to we will continue to respond to. We are compelled by forces that, like the ocean current, are so subtle and pervasive we take them utterly for granted. Those odd moments when we notice the sea we swim in leave us as surprised as the discovery by Moliere’s character that he was speaking prose, that indeed he had always spoken prose.
