For further clarification of its distinctive qualities the phenomenon may be related to and distinguished from other similar phenomena. For example, empathy is similar to and also different from identification, projection, compassion, sympathy, love, and encounter.
By considering what it has in common with other phenomena, the phenomenon being described may be classified as being subsumed in a broader category. Thus, empathy is a human response, a coalescent movement, a form of relating.
The phenomenon may be described by selecting its central or decisive characteristics and abstracting its accidentals. For instance, interpersonal empathy always involves movement into another's perspective and as a form of movement it has directions, dimensions, and degrees. It can occur between persons of difference age, education, experience, sex; these latter characteristics are accidental.
Some descriptions make use of negation. A phenomenon cannot be described completely by negation but it may be clarified to some extent by saying what it is not. For instance, empathy is not sympathy; it is not projection; it is not identification.
Analogy may be used to promote analytic examination and description. This involves a comparison based on partial similarity between like features of two things. For example, the movement of empathy is like the currents in the sea; the heart is like a pump. The advantage of using analogy is that the comparison raises questions about the nature of the phenomenon under consideration. However, since the similarity between the analogues is always partial, one must guard against overextending the comparison to unwarranted conclusions. The description must always be consonant with the phenomenon as it occurs in reality.
The use of a metaphor also may enhance description and analysis. A metaphor suggests comparison of the phenomenon with another by the nonliteral application of a word. For example, "the between is a secret place." The use of metaphor may be criticized in regard to its lack of precision. On the other hand, there are some (for example, Marcel, Buber) who hold that the intersubjective realm can be described only metaphorically because it is {84} beyond the level of objectivity. And to attempt to describe intersubjective phenomena in precise terms related to the physical world would tend to distort rather than clarify. Many of the nursing phenomena requiring description occur within the intersubjective realm. Metaphors could cast some light on these.
CONCLUSION
As a theory of practice, humanistic nursing is derived from individual nurses' actual experiences in their uniquely perceived but commonly shared nursing world. Its development, therefore, depends on the articulation of their angular views and also on the truly collaborative effort of a genuine community of nurses struggling together to describe humanistic nursing practice.
Since the description of nursing phenomena is recognized as a basic and essential step in theory development, this chapter presented an approach and detailed some techniques used by nurses to describe phenomena. It is hoped that these would be viewed critically and creatively; that they would be used, varied, combined adapted, and lead to new methods suited to the description of nursing phenomena. And if they are developed, it is hoped that they will be shared for the growth of humanistic nursing depends not only on using and sharing what we learn but also on describing how we come to know. Then humanistic nursing theory will grow in dialogue.
