Relating in "I-Thou" with the other in-his-clinical-world the clinician gives himself and receives back the other and himself in the sphere of "the between." {109} He knows the other and the more of himself in this relating. He is confirmed and confirms the other through the other's presence with him. Thus, he calls forth the other's actualizing of self through the clinical relationship. In accepting the other as he is the clinician imagines and responds to the reality of his potential for becoming, becoming according to his unique capacity for humanness. Relating in "I-It" with his clinical world the clinician noetically transcends himself, objectifies himself, and studies his "I-Thou" knowing. He teases it apart. He classifies and studies it. He asks it questions. He compares and contrasts it to other clinical experiences. He discusses its many aspects in dialogue with his "inward," and possibly "outward" "Thous." He reorders its parts. He shapes, creates, plans from and for its clinical existence. Thus, he ever augments a world of heuristic knowing. This "how" allows the clinical fulfillment of my nursing "why." Comfort is "why" I, as a nurse, am in the health-nursing situation. As conceptualized "comfort" is being able to freely control and plan for one's self, being fully in accord at a particular time, in a particular situation, with one's unique potential. Now, "what" is the nature of the nurse's world, the health-nursing situation? ALL-AT-ONCE: WHAT The term "all-at-once," arose within me as a construct that would metaphorically describe the multifarious multiplicities that exist within nursing situations. Completing my comparison of Gilbert's and Muller's written works to grasp how they viewed the nature of psychiatric mental health nursing I found myself mulling over and fussing.[18] Your question is probably, mulling and fussing over what? While I mulled over and fussed I believe I, too, was perplexed. Why was I unsatisfied? I had compared Gilbert's and Muller's writing styles, their conceptions of man, approaches to nursing, nursing education, supervision, and consultation. Their similarities and differences were noted, and how each presented herself predominantly. Then I cited the nursing communities they sought to influence and those in which they were while writing. Through reviewing their bibliographies and biographies I indicated the sources that had influenced them. Still I mulled over, fussed, and was perplexed. I awakened in the middle of one night in 1969 understanding what had been causing my struggle. The "all-at-once" was my answer.
