Henry Ford said, "History is Bunk". Why does this society depend upon history being bunk?

Society views history and religion as dangerous and potentially corrupting. Having a history gives people a sense of time outside of their own lifetimes. This in turn makes people think about progression through time, which is something the society cannot permit without causing social upheaval. Thus Huxley uses the quote from Ford, "History is bunk," to indicate that history is worthless and should not be studied. The Controller describes history in a way that further emphasizes its negative aspects. He also blames Christianity for the inability of past societies to achieve ectogenesis (in this context Huxley means growing babies outside of the human body).
