"Some think so," said Leibniz, agreeably enough. "At any rate, it happens that even the Principia Mathematica of Mr. Newton does not even attempt to settle such questions. He avoids these two labyrinths altogether—a wise choice! For in no way does he address the topic of free will versus predestination, other than to make it plain that he believes in the former. And he does not touch on atoms. Indeed, he is reluctant even to divulge his work on infinitesimal mathematics! But do not be misled into believing that he does not have an interest in such things. He does, and toils night and day on them. As do I, and as will Dr. Waterhouse in Massachusetts."
