Regardless of the feeling that he was somehow experiencing a divine communication, Dick was never fully able to rationalize the events. For the rest of his life, he struggled to comprehend what was occurring, questioning his own sanity and perception of reality. He transcribed what thoughts he could into an eight-thousand-page, one-million-word journal dubbed the "Exegesis". From 1974 until his death in 1982, Dick spent many nights writing in this journal. A recurring theme in "Exegesis" is Dick's hypothesis that history had been stopped in the first century AD, and that "the Empire never ended". He saw Rome as the pinnacle of materialism and despotism, which, after forcing the Gnostics underground, had kept the population of Earth enslaved to worldly possessions. Dick believed that VALIS had communicated with him, and anonymously others, to induce the impeachment of U.S. President Richard Nixon, whom Dick believed to be the current Emperor of Rome incarnate.
