Welcome home to sanity, logic, and listening to your horse. Littauer is not confused about much, and he will correct himself in print if he sees and error in his method. If you have a lot of free time now consider ordering OTHER FS books.
Piero Santini, taught by Caprilli himself, is not as crystal clear as Littauer, but his books are worth reading. As an example I had read “Riding Reflections” when I was 20 or so, at that time I did not get much out of it but 23 years later, when I was finally diagnosed with MS, it was one of his discussions about hands that showed me the way forward.
After pages about hands, and the absolute necessity for a strong, independent seat for good hands, he then writes about and exception he personally knew who Santini wrote had the BEST hands Santini had ever seen. Santini wrote that this person, elderly, weak, and with an atrociously insecure seat, managed to ride horses, including bolters, borers, and other bit evaders, with no problems at all because his hands were so soft and he used his hands well. When I looked at my very weak, shaky and crippled nervous system and body, and I remembered that, I concentrated on making my hands soft, responsive to the horse, and on timing my hand aids correctly. This paid off and lets me ride horses who are not the safest for beginners and cripples.
“Forward Freely” by Michael Kirschner is also a good book. Kirschner has a “purer” FS than Littauer, and he taught equitation at Mary Washington College in Virginia (lucky girls!) Since the college could not afford “good horses” he had to deal with whatever the college could afford. It is interesting how the use of the FS transformed these problem horses into productive citizens.
These books are on Amazon and most of them are under $20.00, in fact there is a copy of Kirschner on Amazon for ninety-seven cents!
