I will use treatment to help the sick according to my ability and judgment, but never with a view to injury and wrongdoing. Neither will I administer a poison to anybody when asked to do so, nor will I suggest such a course. Similarly, I will not give to a woman a pessary to cause abortion. I will keep pure and holy both my life and my art.

I have clearly recorded this: for one can learn good lessons also from what has been tried but clearly has not succeeded, when it is clear why it has not succeeded.

Opposites are cures for opposites.

Cure sometimes, treat often, comfort always.

Science begets knowledge; opinion, ignorance.

There are in fact two things, science and opinion. The former begets knowledge, the latter ignorance.
