    would have argued otherwise, if we  had found ourselves in the same situation, in
    the same state of  knowledge."
    
    I agree with that completely, and I would even go a little  farther. If we
    were placed back in time 1800 years with our modern sense of  scientific
    methodology and principles intact, we would still reach the same  conclusion. The
    most damning evidence against the motion of the Earth is the  apparent lack of
    stellar parallax. The reply from advocates of a moving Earth  --"well... maybe
    the stars are really far away..."-- would immediately strike us  an ad hoc
    assumption designed to avoid facing up to observational evidence that  clearly
    rules out the theoretical model. That the ad hoc assumption turns out to  be
    entirely correct is one of those things that makes the history of science
    interesting...
