  • One day the Eccentric was walking along an alleyway when a man fell from a rooftop and landed on him. The other man was unhurt, but the Eccentric was taken to the hospital.

    Later, one of his sons asked him, "Father, you have told us that life itself should be an education, and that a wise man can learn a lesson from any event, but tell me, what can be learned from this occurrence?"

    And the Eccentric answered, "Avoid all theoretical discussion concerning 'cause and effect' and place no faith in the outcome of logical sequence. How can one waste his time speculating on questions such as: 'If a man falls from the roof, will his neck be broken?' The other man fell, but my neck is broken." --"Magnus Machina" by Jan Cox p.130
