Medicine has insurmountable boundaries, and no matter how well it has evolved, there are diseases that cannot be overcome. before the 19th century, the main diseases that killed humans were bacterial and viral infections, but today, with the overall increase in human longevity, degenerative diseases have become the number one life-threatening killer, i.e., those caused by aging organs, such as cancer and cardiovascular diseases. While the disease spectrum is changing, the doctor-patient relationship is equally challenged and the burden on physicians is heavier. Indeed, the patient’s body needs treatment and the mind needs even more comfort. When a person is sick, he is at his most vulnerable and very sensitive to the doctor’s attitude. If he fails to feel the doctor’s compassion, he will be depressed to the extreme and will feel that the world is ugly and life is pathetic, while on the contrary, he will have faith in the world and life. Therefore doctors should think in a philosophical way and give more compassion and care to their patients. Ancient medicine is philosophy, modern medicine is science, and post-modern medicine should be the unification of philosophy and science. Medical students in medical schools should take philosophy as a compulsory course, and a good doctor should be a philosopher with a wise mind and a rich heart at the same time. We always say that the mission of medicine is to save lives, but I think medicine can help the wounded but not the dead, that is to say, to cure the diseases that can be cured, and to improve the quality of life of the patients by giving life care to the diseases that cannot be cured. This requires defining the boundaries and purposes of medicine according to its limitations, so that doctors and patients can form a consensus. In many of today’s doctor-patient disputes, especially those caused by the death of a patient, a very important reason is the inability of the patient to face death with a calm attitude. Since ancient times, Chinese people have an avoiding attitude toward death. Once there is an incurable disease, they have fear and anxiety because there are not many days left, and they even directly refuse and do not admit that they have a terminal disease, and put all their hopes on medicine, thinking that doctors can cure all diseases. Excluding the part of doctor-patient disputes, it is impossible and unrealistic to rely solely on doctors to channel and solve the patients’ fear of death. In the West, there are basically two ways to face death, one is faith and religion, a person with religious beliefs, he believes that the soul has a place to go, in this scenario will be more calm, will not panic; second is a philosophical approach, a person who sees the truth of life, know that death is a natural thing, will have a better state of mind. And in our country, the latter approach will be simpler and easier to implement, if we can all form such an atmosphere, not only to reduce the burden of doctors, but also to let patients and families in the final stage of the real release from fear.
