"If we want more than has been found to be present we are no longer tempted to harass the statistician to work miracles... To consult the statistician after an experiment is finished is often merely to ask him to conduct a post mortem examination. He can perhaps say what the experiment died of."

I'm guessing that Fisher didn't have a big teaching load at the Rothamsted Experimental Station.
