Medicine
Medicine is the science and practice of the diagnosis, treatment, and prevention of disease. Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness. Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease, typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.
Therapy
Therapy (often abbreviated tx, Tx, or Tx) is the attempted remediation of a health problem, usually following a diagnosis. In the medical field, it is usually synonymous with treatment (also abbreviated tx or Tx). Among psychologists and other mental health professionals, including psychiatrists, psychiatric nurse practitioners, counselors, and clinical social workers, the term may refer specifically to psychotherapy (sometimes dubbed 'talking therapy'). The English word therapy comes via Latin therapīa from Greek: θεραπεία and literally means "curing" or "healing".
Medicine
The ignorance and general incompetency of the average graduate of the American medical Schools, at the time when he receives the degree which turns him loose upon the community, is something horrible to contemplate.
Charles Eliot, President of Harvard University (1869). In response to this call for reform, Harvard Professor of Surgery Harold Bigelow replied "He actually proposes to have written examinations for the degree of doctor of medicine. I had to tell him that he knew nothing about the quality of Harvard medical students. More than half of them can barely write. Of course they can't pass written examinations...No medical school has thought it proper to risk large existing classes and larger receipts by introducing more rigorous standards".
Therapy
Most therapists do not appear to know how to pinpoint and reverse therapeutic resistance - to head it off at the pass. Instead, they try to persuade the patient to change, or to do the psychotherapy homework, while the patient resists and 'yes-butts' the therapist. The therapist ends up feeling frustrated and resentful, and doing all the work.
