The hippocratic oath and ethics in medicine

For the last number of years, when ethical problems were discussed in Germany in public, the hippocratic oath was quoted as the valid norm for medical ethics. Although no physician swears this oath in Germany, it is necessary to know its contents, its origin and its role in the history of medicine. And it is necessary to ask some questions: What are the ethical claims of the hippocratic oath? Does it really originate from Hippocrates? How and why did the hippocratic oath become the 'Magna Carta' of behaviour for physicians? Do specific medical ethics exist over time? Do specific medical ethics exist in general? And if it exists, can it be normative ethics? A short survey of the multiple dependences of medical situations shows that ethics in medicine must undertake a new beginning. It cannot be normative ethics, it cannot be situation ethics, it must be differential ethics. It has to respect rules and declarations, but it has also to compare the benefits and risks. In the center of such ethics stands the responsibility of the physician. To assume this responsibility, the physician needs knowledge, the ability to make decisions and a conscience.
