"Finally, with regard to this time-binding, a man cannot live beyond the grave. Each generation that discovers something from its experience must pass that on, but it must pass that on with a delicate BALANCE of respect and disrespect, so that the [human] race–now that it is aware of the disease to which it is liable–does not inflict its errors too rigidly on its youth, but it does pass on the ACCUMULATED WISDOM, plus the wisdom that it may not be wisdom." (emphasis added)
Richard Feynman doesn't discount 'Expertise'...he counsels continued exploration THROUGH the use of scientific tools, expertise and methods and not blind acceptance of what current science has documented...IMHO...and in regard to our current COVID-19 pandemic, I also believe that this process is being dealt with in a proper scientific manner...which 'weeds out' non-effective offerings, such as Hydroxychloroquine and Ivermectin.
btw, you should get the boxed set of "The Feynman Lectures on Physics", and/or watch many of his YouTube lessons...what a fantastic man.
