Hippocrates, born about 460 BC, lived in an era when there were no medical
schools and no medical profession as we now know it.

Although the Oath laid the foundation for the ethical ideals to which medical
practitioners should aspire, its detailed wording, relevant to social conditions
prevailing 2400 years ago, is not appropriate to the practice of modern
medicine.

Consequently few, if any, medical schools require their students to take
the original form of the Oath.

The oaths required by various medical schools vary from none at all, to
edited statements which reveal their historic origins, to modern statements
that bear no resemblance to the original Oath.

An example of a modern statement is provided by the following Declaration,
in use at the Faculty of Medicine, Adelaide University.

• At the time of being admitted as a member of the medical profession
  I solemnly pledge myself to consecrate my life to the service of humanity;
• I will give to my teachers the respect and gratitude which is their
  due;

• I will practice my profession with conscience and dignity;

• The health of my patients will be my first consideration;
• I will respect the secrets which are confided in me, even after a patient
  has died;
• I will maintain by all means in my power the honour and the noble traditions
  of the medical profession;
• I will not use my medical knowledge contrary to the laws of humanity;
• I make these promises solemnly, freely and upon my honour.

With this type of oath the permissability of voluntary euthanasia hinges
on how the doctor's conscience interprets "the laws of humanity". While
demanding the highest ethical standards, such an oath does not rule out
the possibility of circumstances arising in which requested help to a hastened
death may rightly be given.
