"Just so. You instead would see him melting things in crucibles or dissolving them in acids. What do such activities have to do with atoms? The answer is that Newton, unable to see atoms with even the finest microscope, has said, ‘If my notion of atoms is correct, then such-and-such ought to happen when I drop a pinch of this into a beaker of that.’ He gives it a go and sees neither success nor failure but some other thing he did not anticipate; then he goes off and broods over it, and re-jiggers his notions of atoms, and devises a new experimentum crucis, and re-iterates. Likewise, if your highness were to visit Massachusetts and see me at work in my Institute, you’d not see any monads lying about on counter-tops. Rather you would see me toiling over machines that are to thinking what beakers, retorts, et cetera, are to atoms: Machines that, like monads, apply simple rules to information that is supplied to them from without."
