Although it is possible to view a person as an object, persons and things are necessarily different kinds of objects. A thing, as object, is open to a subject's scrutiny, while a person, as object, can make himself knowable or set up barriers to objectification. He can keep his thoughts to himself, remain silent, or deliberately conceal some of his qualities. Through the scientific objective approach, that is, subject-object relating, it is possible to gain certain knowledge about a person; through intersubjective, that is, subject-subject relating, it is possible to know a person in his unique individuality. Thus, both subject-subject and subject-object relationships are essential to the clinical nursing process. Both are integral elements of humanistic nursing. Presence In the nursing world, as in the world at large, human encounters may range from the trivial to the extremely significant. Within a day's work, the nurse may experience many levels of intersubjectivity from the lowest level of being called on as a function or being used as an object, to the other end of the scale of being recognized as a presence or a thou in genuine dialogue. Nursing activities bring a nurse and patient into close physical proximity, but this in itself does not guarantee genuine intersubjectivity in which a man relates to another person as a "presence" rather than an object. A presence cannot be grasped or seized like an object. It cannot be demanded or {28} commanded; it only can be welcomed or rejected. In a sense, it lies beyond comprehension and can only be invoked or evoked. There is a quality of unpredictableness or spontaneity about genuine dialogue. A nurse may be going through her daily activities, functioning effectively, relating humanely, when suddenly she is stopped by something in the patient, perhaps a look of fear, a tug at her sleeve, a moan, a reaching for her hand, a question, emptiness. In a suspenseful pause two persons hover between their private worlds and the realm of intersubjectivity. Two humans stand on the brink of the between for a precious moment filled with promise and fear. With my hand on the doorknob to open myself from within, I hesitate--should I, will I let me out, let him in? Time is suspended, then moves again as I move with resolve to recognize, to give testimony to the other presence.
