The quote comes from Arthur C. Clarke. He was an assistant editor of Physics Abstracts, and president of the British Interplanetary Society. His book, The Exploration of Space, was used to help convince Kennedy that humans could go to the Moon. As one of the most influential science and science fiction writers of his time, in 2000, he was made a Knight Bachelor by the British Crown for his services to literature. His record of personal intellectual achievement, and work on advancement of science is pretty unimpeachable.
Maybe watch who you call an, "ignorant hole person."
