Oldenburg did not yet know the magnitude of Isaac's powers. Not that Oldenburg was stupid – he was anything but. But Isaac, unlike, say, Leibniz the indefatigable letter-writer or Hooke the Royal Society stalwart, did not communicate his results, and did not appear to socialize with anyone save daft Alchemists. And so in Oldenburg's mind, Newton was a clever though odd chap who'd written a paper about colors and then got into a fracas over it with Hooke. If Newton would only mingle with the Fellows a bit, Oldenburg seemed to believe, he would soon learn that Hooke had quite put colors out of his mind and moved on to matters such as Universal Gravitation, which of course would not interest young Mr. Newton in the slightest.
