"I swear by Apollo the Physician, by Aesculapius, and by all the gods and goddesses, making them my witnesses, that I will carry out, according to my ability and judgement this oath.
To hold my teacher in this art equal to my own parents; when he is in need of money to share mine with him; to consider his family as my own brothers and to teach them this art, without fee or indenture; to impart precept, oral instruction, and all other instruction to my own sons, the sons of my teacher, and to indentured pupils.
I will use treatment to help the sick according to my ability and my judgement, but never with a view to injury and wrongdoing.
I will not administer a poison to anybody when asked to do so, nor will I give a woman a pessary to cause abortion. But I will keep pure and holy in both my life and my art.
I will not use the knife on sufferers from stone, but I will give place to such as are craftsmen in this art.
Into whatsoever houses I enter I will endeavour to help the sick and I will abstain from all intentional wrongdoing and harm, especially from abusing the bodies of man or woman whether bond or free.
And whatsoever I shall see or hear in the course of my profession, or in my intercourse with men, if it be what should not be published abroad I will never divulge it, holding such things to be as secrets which are holy.
If I carry out this oath and break it not, may I gain forever a good reputation among all men for my life and my art; but if I transgress it, may the opposite be my portion.”
(Oh, so that's why they don't have doctors swear to it anymore.)
