The Medical Model and the Precautionary Principle

Eric Chivian MD, Center for Health and the Global Environment, Harvard University, with a powerful oration.


  1. It was a great speech, but very academic in tone and presentation, and not recorded loud enough. I don't think it reaches past the choir much, but of its kind very fine.

    Exploring suggested videos I came across this gem from Feynman:

    "The basic principle of knowing about something rather than just knowing its name is something that you have stuck to, isn't it?

    "Yes, of course. We have to learn that these are the kinds of disciplines in the field of science that you have to learn – to know when you know and when you don't know, and what it is you know and what it is you don't know. You've go to be very careful not to confuse yourself."

    Unfortunately, anyone can take this to mean whatever they want, but there's the kernel - that people must learn their discipline before they know what they know and what they don't know. There's the rub.
