Over his Atheism? What you mean the guy that nearly didn't write the principia because he was so into his theologjcal research. That is from chapter 3 of Gleik on Newton many more similar references out there. Hell he even has religous discussion in the margins of his copy of the first edition (in rare books @ fisher at usyd - where i study). Newton was nuts, he was odd, he argued against the catholic church and their stubborn arguments for geocentrism but he was a pious man. He was no more athiest than Darwin or Milton.
