"The sages did not treat those already ill, but treated those not yet ill, they did not put in order what was already in disorder, but put in order what was not yet in disorder, ... when drugs are employed for therapy only after a disease has become fully developed, when restoring order are initiated only after disorder has fully developed, this is as if a well were dug when one is thirsty, and if weapons were cast when the fight is on. Would this not to be too late, too?"
(Unschuld & Tessenow, 2011)
