An irrefutable law is a law that is impossible to deny or disprove. Gravity is an irrefutable law. We can circumvent this law if we apply power to an airplane. Then the law of lift prevails - until power fails and the law of gravity takes over. With horses, there are certain laws that cannot be argued with. Often horse owners circumvent them as lift overrides gravity. But in the end, luck runs out. In this book, Laws 1 through 4 apply to the physical handling of the horse. Laws 5 through 10 are the psychological laws.
