noah speaks

I get a newsletter now and then from these folks. As a longtime employee of the big fish eatin' the little fish in the American healthcare system, I pay attention when they speak. I doubt I'll travel across the globe to save a life, but wouldn't it be nice if it weren't all about making money for the stockholders and the corporate higher ups?
"Declare the past, diagnose the present, foretell the future; practice these acts. As to diseases, make a habit of two things — to help, or at least to do no harm."
Who said it?
