Introduction by Jon Wiener. A how-to book for activists written at one of the darkest moments of the Nixon years, it remains relevant and useful today. The book takes up the question of what we can do, what we should do, about a president who fills us with dread and rage. “What is to be done?” is of course the classic question for leftists facing oppressive regimes and long odds. Walzer’s book is “an invitation to commitment and participation,” to get together in groups, to argue at meetings, and then to go out and talk to people. The book has been republished in 2019 by New York Review Books at the suggestion of some high school students in Los Angeles.
