Your Father’s a Fighter; Your Daughter’s a Vegetable: A Critical Analysis of the Use of Metaphor in Clinical Practice by TYLER TAT E Military metaphors are often thought to be harmful to patients, and some writers have proposed that empirical research could determine whether a metaphor is fit or ill for health care. But the “best” metaphor for a patient encounter can be known only from within the patient-clinician relationship. A conceptual framework can, however, give clinicians preliminary guidance for evaluating metaphors. No word can be judged as to whether it is good or self to be rational and value neutral.5 Trope skepticism bad, correct or incorrect, beautiful or ugly, or anything runs deep in health care. else that matters . . . in isolation.
