Free men and women... can think across time, viewing their own lives, inclusive of past, present, and future, as architectural wholes, static in mental space. They can therefore see, as others cannot, the cracks and buttresses of repeated action, the points of stress, the established framework. They are not perfect; but they are less imperfect than we by a full dimension of being.
In a railroad car at nightfall, when the natural light outside has diminished until it is even with the artificial light inside, the passenger facing forward sees in his window two images at once: the dim landscape rushing toward him out of a pit of darkness, and the interior of the car, reflected with its more or less motionless occupants. At this hour most passengers unconsciously give allegiance to one of these two polarities of vision; and the individual momentarily aware of both may be struck by the profound, almost tragic duality between outer and inner worlds, between the rush of experience and the immobility of awareness.
