In his later years, Vidal gave up writing longer novels, and published two volumes of memoirs, Palimpsest (1995) and Point to Point Navigation (2006). He also published a thoughtful study of the Founding Fathers, Inventing a Nation: Washington, Adams, Jefferson (2003). He continued to publish book-length essays on political topics, such as Dreaming War and Imperial America. Until his final illness, he continued to speak publicly against what he saw as the erosion of constitutional liberty in America. His ability to say what everyone secretly knows and to make it unsettling without worrying about the implications, for himself or his reputation, was a particular gift. This habit won him many admirers and numerous enemies over the years. Gore Vidal died at home in Los Angeles at the age of 86.
