It is satisfactory, as showing how transient such impressions are, to remember that the greatest discovery ever made by man, namely, the law of the attraction of gravity, was also attacked by Leibnitz, "as subversive of natural, and inferentially of revealed, religion."
Horrelako inpresioak zein iragankorrak diren frogatzeko nahikoa da gogoratzea Leibnitzek, gizakiak egundo egin duen aurkikunderik handiena, hots, grabitatearen erakarpenaren legea, "erlijio naturalaren, eta, ondorioz, errebelatuaren iraulgarri" zela esanez eraso zuela.
