“Then she understood that what she needed was the motion to a purpose, no matter how small or in what form, the sense of an activity going step by step to some chosen end across a span of time. The work of cooking a meal was like a closed circle, completed and gone, leading nowhere. But the work of building a path was a living sum, so that no day was left to die behind her, but each day contained all those that preceded it, each day acquired its immortality on every succeeding tomorrow. A circle, she thought, is the movement proper to physical nature, they say that there s nothing but circular motion in the inanimate universe around us, but the straight line is the badge of man, the straight line of a geometrical abstraction that makes roads, rails and bridges, the straight line that cuts the curving aimlessness of nature by a purposeful motion from a start to an end. The cooking of meals, she thought, is like the feeding of coal to an engine for the sake of a great run, but what would be the imbecile torture of coaling an engine that had no run to make? It is not proper for man s life to be a circle, she thought, or a string of circles dropping off like zeros behind him–man s life must be a straight line of motion from goal to farther goal, each leading to the next and to a single growing sum, like a journey down the track of a railroad, from station to station to–oh, stop it!”
