“Most of what you burned anyway was twaddle. You’ll see none of it here. Yet here I am infinitely closer to the Grand Magisterium.”
“I know you have torn Alchemy down to its foundations, and built it back up, and are recording it in a book called Praxis, which will be to Alchemy what Principia Mathematica was to physics. And perhaps ’tis hoped that in combination with some new reading of scriptures from Fatio, here, and new philosophy from Locke, there, and a reworking of Christianity on Arian principles from your disciples scattered round England, it shall all come together in some grand unifying discourse, a kind of scientific apocalypse in which the whole universe, and all history, shall be made clear as distilled water.”
“You mock us, by making it simple.”
“It is not simple, then? ’Twill not all happen at once, in a flash?”
“It is not for us to say in advance the manner of how it might happen.”
“Yet you have been awake five nights tending some work that you’ll not entrust to any assistant. You suffer obvious ill effects of quicksilver poisoning. You will not admit it is the Great Work, but what else could it be? And I cannot read your mind, Isaac, or ask you to divulge secrets, but I can see plainly enough that it failed. And if it was meant to combine with Fatio’s theory of gravity, then that has failed as well.”
“Before you mock our work, sir, prithee tell us in what way Leibniz’s has succeeded,” Fatio demanded.
“His differs from yours in that it does not need to succeed—only not to fail. And I take that to be a more sound way of doing science than your approach, which is all-or-nothing. For as I grow older and see new men coming into the Royal Society I perceive that though Natural Philosophy may have begun with our generation, it need not end with us. Nor am I alone in thinking so.” Daniel now lifted up a sheet he had taken from Locke’s study, and read: “It is of great use to the sailor to know the length of his line, though he cannot with it fathom all the depths of the ocean. It is well he knows that it is long enough to reach the bottom, at such places as are necessary to direct his voyage, and caution him against running upon shoals that may ruin him.”
“What sniveling fool penned that nonsense?” Fatio demanded.
“Mr. John Locke. And the ink is still damp on it,” Daniel replied.
“I am quite sure he did not mean it to apply to Isaac Newton!” Fatio returned, jarred, but recovering quickly.
“I believe what you really mean to say is, ‘Newton and Fatio,’ ” Daniel said.
Newton and Fatio looked at each other, and Daniel looked at them. Fatio had a kind of tender, insinuating look on his face, and Daniel got the idea it was very far from the first time he had shown that sort of face to Newton, and that Fatio was used to seeing a tender and loving face looking back his way. But not today. Newton was staring at Fatio not with love, but with avid curiosity, as if suddenly perceiving what had escaped his notice before. Daniel had no love for Fatio, but this made him so uneasy that he lost the courage he’d maintained up until now.
“I wish to tell you a story about Robert Hooke,” he announced.
This was one of the few things that could get Isaac’s attention away from his minute, penetrating study of Nicolas Fatio de Duillier. He turned his eyes toward Daniel, who went on: “Before I came up to Woolsthorpe, Isaac, I did an experiment with him. We set up a scale above a well, and weighed the same object at the level of the ground, and again three hundred feet below it, to see if there was a difference. For you see, Hooke had an inkling of the inverse-square law.”
Isaac did a little calculation in his head and said, “There was no observable difference.”
“Just so. Hooke was let down, of course, but as we drove home he conceived a refinement of the experiment, which has never been carried out. But the point of the story is that our colloquium at Epsom succeeded at much, but failed in that, its most ambitious effort. Did it mean the end of Natural Philosophy? No. The end of Hooke’s career, or Wilkins’s, or mine? By no means. On the contrary, it led straight on to a flourishing of all those things. Which has led me to mistrust apocalyptic readings of Science or of Society. I have not been quick to learn that lesson, either. For example, I phant’sied that the Glorious Revolution would change all, but now I see that Cavaliers and Roundheads have only been replaced by Tories and Whigs, and the war goes on.”
