To some extent, you have to be a crank to have the confidence and persistence in opposing the vast majority of established thought long enough to discover something new. "The distance between genius and insanity is measured only by success."

Of course, that doesn't mean that the rest of us are obligated to listen to any of it until that success has been realized.
