In the Air
The arguments of Bruce and Shulman suppose that great ideas are precious. It is too much for them to imagine that a discovery as remarkable as the telephone could arise in two places at once. But five people came up with the steamboat, and nine people came up with the telescope, and, if Gray had fallen into the Grand River along with Bell, some Joe Smith somewhere would likely have come up with the telephone instead and Ma Smith would have run the show. Good ideas are out there for anyone with the wit and the will to find them.
