The first term, "comfort," was developed as a construct in 1967. After recording and exploring my clinical experiential data, a conceptualized response emerged to my question: "Why, as a nurse, am I in the clinical health-nursing situation?" The second term, "clinical," was developed as a construct in 1968. It was a conceptualized response to a dialectical process within myself. I asked, "What is clinical?" I answered, "I am a clinician." I asked, "As a nurse clinician what do I do; what is the condition of my being in the nursing situation?" I answered, "This described would equate to clinical." Consequently I compared and contrasted two nursing experiences similarly labeled to properly grasp the principle of "clinical" for conceptualization. The third term or phrase, "all-at-once," arose intuitively within me as a construct in 1969 and was partially conceptualized. It arose after mulling over other nurses' published clinical data and asking, "What can you tell me of the clinical nursing situation?" "What do you perceive as the nature of nursing?" Therese G. Muller's, Ruth Gilbert's and my thought on the nursing situation merged into a view of these as multifariously loaded with all levels of incomparable data, the "all-at-once." Incommensurables relate to the nature of nursing and its concerns. How can one study unrelated appearances? Muller often used an historical approach while Gilbert emphasized individualization. In humanistic nursing practice theory a descriptive, intersubjective, phenomenological approach is proposed for greater understanding and attestation of the events and process of the nursing situation. The construction of "comfort, clinical, and all-at-once" I would now label as conceptualized phenomenologically. I view them as relevant phenomena to any nurse and this nurse-in-her-nursing-world.
