Prescribing a "sugar pill" (placebo) and deliberately misleading a patient is seen as deceptive. Does honesty necessarily mean simply telling the truth? A more nuanced view would consider authenticity, which means being real rather than merely being truthful. A cartoon showed a nurse cheerfully responding to a little girl in the cancer ward who has just asked, "Will you come and visit me after I leave here?" The nurse responds, "Absolutely not, I hate cemeteries." Manipulation is a part of every relationship, but it can be benevolent, depending upon the question of whose needs are being met, and how. Every relationship involves some degree of trust. Who, besides yourself, do you trust to know what is best for you?
