Raised to be a committed Marxist by communist intellectual parents, Horowitz was in on the ground floor of Berkeley activism, and through his work as an editor at Ramparts magazine, he emerged as a key player in the New Left. He went on to become an active supporter of the Black Panthers and something of an intimate of their founder, Huey P. Newton. Yet today he is an outspoken political conservative who has supported many right-wing causes (such as the contras in Nicaragua) and been critical of '60s radicalism in general. It would be easy to conclude that Horowitz went from A to Z this way because he's superficial and unstable. Instead, as this moving, intellectual autobiography shows, his second thoughts about leftism emerged gradually as he experienced various aspects of the "Movement." The catalytic episode came when he discovered that the Panthers had murdered a friend of his, but even then Horowitz was slow to convert, primarily because he was heavily enmeshed in what he now views as the quintessential leftist habit of judging politics by its intentions, not its acts.
