Do No Harm

• I will neither give a deadly drug to anybody if asked for it, nor will I make a suggestion to this effect... I will apply, for the benefit of the sick, all measures [that] are required, avoiding those twin traps of over-treatment and therapeutic nihilism... I will not be ashamed to say "I know not,"... In purity and holiness I will guard my life and my art.
