Edgar Rice Burroughs

Skeleton Men of Jupiter Edgar Rice Burroughs

I am no scientist. I am a fighting man. My most beloved weapon is the sword, and during a long life I have seen no reason to alter my theories as to its proper application to the many problems with which I have been faced. This is not true of the scientists. They are constantly abandoning one theory for another one. The law of gravitation is about the only theory that has held throughout my lifetime--and if the earth should suddenly start rotating seventeen times faster than it now does, even the law of gravitation would fail us and we would all go sailing off into space. Theories come and theories go--scientific theories. I recall that there was once a theory that Time and Space moved forward constantly in a straight line. There was also a theory that neither Time nor Space existed--it was all in your mind's eye. Then came the theory that Time and Space curved in upon themselves.
