The Longest Journey by E.M. Forster

The mists that had gathered round Rickie seemed to be breaking. He had found light neither in work for which he was unfitted nor in a woman who had ceased to respect him, and whom he was ceasing to love. Though he called himself fickle and took all the blame of their marriage on his own shoulders, there remained in Agnes certain terrible faults of heart and head, and no self-reproach would diminish them. The glamour of wedlock had faded; indeed, he saw now that it had faded even before wedlock, and that during the final months he had shut his eyes and pretended it was still there. But now the mists were breaking.

That November the supreme event approached. He saw it with Nature's eyes. It dawned on him, as on Ansell, that personal love and marriage only cover one side of the shield, and that on the other is graven the epic of birth. In the midst of lessons he would grow dreamy, as one who spies a new symbol for the universe, a fresh circle within the square. Within the square shall be a circle, within the circle another square, until the visual eye is baffled. Here is meaning of a kind. His mother had forgotten herself in him. He would forget himself in his son.
