While searching for the source of a quote, I came across this, which I thought was apropos:
“There are three principal means of acquiring knowledge. . . observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination.”
Denis Diderot
1713 – 1784
(was searching for the source of this quote, which is also his :“Men will never be free until the last king is strangled with the entrails of the last priest”)
