As a Renaissance figure, Dr. osler's speeches and works are allusions, rich in content, beautiful in rhetoric, full of wisdom and thought-provoking. He has answered many medical questions that puzzle us today. Is medical practice a combination of science, trade, industry, specialty or something? Osler said in The Golden Rule of Medical Practice: "Medical practice is an art based on science. It is a profession, not a transaction; It is a mission, not an industry; In essence, medicine is a mission, a social mission, an expression of human nature and emotion. This task requires you to use your heart as your brain. " This sentence has been quoted a lot on different occasions. Indeed, from the day we choose to be a doctor, we should realize that doctors are more than just a profession. We are here to save people, which gives this profession a kind of "divinity". We are not dealing with machinery or cold stones. Facing the life with boiling blood, we are required to think about how to treat it with our brains, but also to feel, help and comfort with our hearts. Osler insisted that patients should be treated humanely, not as an "interesting case". He said: "You are about to face a person who lives in depression. You live much happier than he does. When he meets you, he will be unreasonable and will inevitably disturb your inner peace. " This man's future is uncertain, not only because of our technology, but also because he is a man of flesh and blood, hope and fear like us. "The contradiction between doctors and patients has been like this 100 years. As osler said, the only way is to keep innocent peace. It is calm in a storm, sober judgment in a major crisis, mountain-like immobility and inner peace. With this quality, when the patient's condition changes rapidly, he can concentrate on professional considerations without being affected; Only when the patient is unreasonable can he calmly tolerate people in pain.
